Furthermore, conventionally, as a cleaning device for cleaning an object to be cleaned, a cleaning device including a rotating brush is known (see, for example, Patent Document 1). In such a cleaning device, a rotating brush contacts the object to be cleaned (such as piping) and cleans the object, thereby removing foreign matter adhering to the object to be cleaned.

JP2018-71831A

The conventional cleaning work as described above requires a great deal of time, effort, and cost, and cannot be said to be an efficient work. In addition, since the cleaning device can only clean the area that the rotating brush comes into contact with, it cannot be said that the area that can be cleaned at the same time is sufficiently wide, so it is not efficient.

The present invention has been made in view of the above, and its purpose is to provide a cleaning device system and a cleaning method that can simultaneously clean a wide range of objects to be cleaned in a simple manner without much effort. That's true.

Thereby, purge cleaning using the fluid injected from the injection port and cleaning using the wire can be performed simultaneously. Therefore, a wide range of objects to be cleaned can be cleaned simultaneously in a simple manner without much effort. Further, since the wire is formed of a string-like body, when the wire comes into contact with the object to be cleaned, the wire can easily deform to follow the shape of the object to be cleaned. In this respect as well, a wide range of objects to be cleaned can be cleaned simultaneously with a simple method without much effort. In addition, the wire can be freely adjusted to fit the shape of the object to be cleaned and wrap around it, and has a high bending effect, so it can scrape away foreign matter adhering to the object to be cleaned.

(Embodiment 1)
Hereinafter, a cleaning device system 20 and a cleaning method according to Embodiment 1 of the present invention will be described with reference to the drawings. In each of the following embodiments, the same or corresponding configurations may be denoted by the same reference numerals and the description thereof may be omitted as appropriate. Further, in the drawings of the present application, XYZ orthogonal coordinates are illustrated for reference. Of these orthogonal coordinates, the Z direction corresponds to the upper direction, and the -Z direction corresponds to the lower direction (the direction in which gravity acts).

FIG. 1 is a diagram for explaining the configuration of a part of an incineration facility 10 in which a cleaning device system 20 according to the present embodiment is used. In the incineration according to this embodiment, a pipe is used as an example of the object to be cleaned. Specifically, the object to be cleaned according to the present embodiment is a pipe (specifically, a heat exchange pipe) of the waste incineration facility 10. The incineration facility 10 shown in FIG. 1 includes a first chamber 11a, a second chamber 11b, and a third chamber 11c as heat exchange chambers for cooling combustion gas (GA) after burning waste etc. . In addition, in FIG. 1, illustration of the internal structure of the first chamber 11a, the second chamber 11b, and the third chamber 11c is omitted. A plurality of pipes through which the refrigerant passes are arranged in each of the first chamber 11a, the second chamber 11b, and the third chamber 11c. Combustion gas generated in an incinerator that burns waste is cooled by exchanging heat with the refrigerant passing through the pipes while passing through the first chamber 11a, second chamber 11b, and third chamber 11c. be done.

FIG. 2 is a diagram showing how cleaning is being performed by the cleaning device system 20. The cleaning device system 20 according to the present embodiment is applied to the third chamber 11c of the incineration facility 10, as an example, and specifically, the cleaning device system 20 is applied to a plurality of pipes (pipes 12-1a to 12-12) in the third chamber 11c. 4c) is used for cleaning. In addition, in FIG. 2, a plurality of piping is shown in cross-sectional view. These pipes each extend in the horizontal direction (in FIG. 2, a direction parallel to the Y-axis).

The pipes 12-1a, 12-2a, 12-3a, 12-4a (these pipes are called the first pipe row) are connected to the pipes 12-1b, 12-2b, 12-3b, 12-4b (these pipes are called the first pipe row). The pipes are arranged on the -X direction side of the pipes (referred to as the second pipe row). The pipes 12-1c, 12-2c, 12-3c, and 12-4c (these pipes are referred to as a third pipe row) are arranged closer to the X direction than the second pipe row. Because the arrangement density of the piping rows in this third chamber 11c is high (in other words, because the distance between adjacent piping rows is narrow), it is difficult for cleaning workers to set up scaffolding when performing cleaning work. It is not easy to secure enough space. However, even in such a place, cleaning work can be easily performed according to the cleaning device system 20 according to the present embodiment, as described later.

Cleaning device system 20 includes at least one cleaning device. That is, the cleaning device system 20 may include only one cleaning device, or may include a plurality of cleaning devices. The cleaning device system 20 according to this embodiment includes, for example, a plurality of cleaning devices. Specifically, the cleaning device system 20 includes, as an example, six cleaning devices (cleaning devices 30-1a, 30-2a, 30-3a, 30-1b, 30-2b, and 30-3b). Since the configuration of each cleaning device is similar, the configuration of the cleaning device will be described using the cleaning device 30-1a as an example.

FIG. 3 is a front view of the cleaning device 30-1a. FIG. 4(A) is a cross-sectional view taken along line A1-A1 in FIG. FIG. 4(B) is an enlarged view of portion B1 in FIG. 4(A). FIG. 5 is a sectional view of the B2 portion in FIG. 3. Specifically, FIG. 5 schematically shows a cross section taken along a plane including the axis of the pipe 31-1a at the B2 portion in FIG.

As shown in FIG. 3, the cleaning device 30-1a includes a pipe 31-1a, a rotating body 32, connecting members 38a, 38b, rotation guides 33a, 33b, and a wire 34.

The pipe 31-1a extends in a direction parallel to the Z-axis. That is, the axial direction of the pipe 31-1a according to this embodiment is the vertical direction (direction perpendicular to the ground). Fluid (FL) pumped from a fluid supply device 150 (shown in FIG. 2) is supplied to the pipe 31-1a. Gas or liquid can be used as this fluid. As the gas, for example, air, inert gas, etc. can be used. As the liquid, for example, water or a cleaning liquid containing a cleaning agent in water can be used. In this embodiment, air is used as an example of the fluid. Further, when air is used as the fluid, an air compressor, an air cylinder, or the like can be used as the fluid supply device 150, for example. When a liquid is used as the fluid, a fluid pump or the like can be used as the fluid supply device 150.

Note that, for example, if a fluid supply device provided in advance in the incineration facility 10 is used as the fluid supply device 150, the cost of separately preparing a fluid supply device can be reduced.

As shown in FIGS. 4(A) and 4(B), the fluid passing through the inside of the pipe 31-1a is injected outward in the radial direction of the pipe 31-1a onto the side wall 31a of the pipe 31-1a. At least one nozzle hole 35 is provided. For example, a plurality of nozzle holes 35 are provided in the pipe 31-1a according to the present embodiment in the circumferential direction of the pipe 31-1a.

As shown in FIGS. 3, 4(A), and 4(B), the rotating body 32 is disposed radially outside the pipe 31-1a. The axis of the rotating body 32 coincides with the axis of the pipe 31-1a. The rotating body 32 is fitted into the pipe 31-1a so as to be rotatable relative to the pipe 31-1a. The rotating body 32 is driven and rotated by fluid injected from the nozzle hole 35 of the pipe 31-1a. The rotating body 32 also includes an injection port 36 (shown in FIG. 4(B)) that injects the fluid that has been subjected to the rotation of the rotating body 32 outward in the radial direction of the rotating body 32. ing. Specifically, the rotating body 32 according to this embodiment has the following configuration.

First, the rotating body 32 according to this embodiment includes a plurality of blades 37. The plurality of blades 37 are arranged to surround the pipe 31-1a. The connecting members 38a and 38b are constituted by annular members. The ends of the plurality of blades 37 in the Z direction are connected by a connecting member 38a, and the ends of the plurality of blades 37 in the -Z direction are connected by a connecting member 38b. Note that the connecting members 38a and 38b rotate together with the rotating body 32 (blade 37) when the rotating body 32 rotates.

The connecting members 38a, 38b are rotatably connected to the pipe 31-1a by rotation guides 33a, 33b with respect to the pipe 31-1a. Specifically, the rotation guides 33a and 33b are fixed to the pipe 31-1a by fitting into the pipe 31-1a. This prevents the rotation guides 33a and 33b from rotating when the rotating body 32 rotates. As shown in FIG. 5, when the rotation guide 33a is fitted into the pipe 31-1a, an annular groove 33a-1 is formed between the rotation guide 33a and the pipe 31-1a. By fitting the connecting member 38a into this groove 33a-1, the connecting member 38a rotates with respect to the pipe 31-1a without being displaced in the axial direction (Z-axis direction) with respect to the pipe 31-1a.

The rotation guide 33b also has the same configuration as the rotation guide 33a. That is, the rotation guide 33b is also configured to form an annular groove between the rotation guide 33b and the pipe 31-1a when the rotation guide 33b is fitted into the pipe 31-1a. By fitting into the groove between the rotation guide 33b and the pipe 31-1a, the connecting member 38b rotates with respect to the pipe 31-1a without being displaced in the axial direction with respect to the pipe 31-1a.

As shown in FIG. 4(B), the rotating body 32 rotates relative to the pipe 31-1a as the blades 37 receive the pressure of the fluid injected from the nozzle hole 35 of the pipe 31-1a. (That is, it is driven and rotated by the fluid injected from the nozzle hole 35). For reference, in FIG. 4(B), the rotation direction of the rotating body 32 is shown as "RT".

Further, a gap 37a is provided between adjacent blades 37 through which the fluid jetted from the nozzle hole 35 can pass. This gap 37a has a function as the injection port 36 described above. Thereby, the fluid after being injected from the nozzle hole 35 is injected outward in the radial direction of the rotating body 32 from this gap 37a (injection port 36). Note that the object to be cleaned is purged and cleaned by the fluid injected from the injection port 36. The rotating body 32 has the above configuration.

As shown in FIGS. 3 and 4(A), the wire 34 according to this embodiment is connected to the rotating body 32. Specifically, the wire 34 according to this embodiment is connected to the outer peripheral surface of the blade 37 of the rotating body 32. Thereby, the wire 34 rotates together with the rotating body 32 when the rotating body 32 rotates.

Moreover, the wire 34 according to the present embodiment has one end connected to the blade 37, and the other end connected to "a different part of the blade 37 to the part to which one end of the wire 34 is connected". As a result, the wire 34 has an overall loop shape. Note that the connection location of the wire 34 is not limited to the rotating body 32, as long as the wire 34 can rotate together with the rotating body 32 when the rotating body 32 rotates. The wire 34 may be connected to a member that rotates together with the rotating body 32 (for example, in this embodiment, the connecting members 38a, 38b, etc.).

Further, the number of wires 34 included in the cleaning device 30-1a according to the present embodiment is, for example, plural. Specifically, the cleaning device 30-1a includes two wires 34. In this embodiment, these two wires 34 are connected to the blades 37 such that the other wire 34 is located on the opposite side of the rotating body 32 from one wire 34 . However, the number of wires 34 is not limited to two, and may be one or three or more.

When the wire 34 rotates together with the rotating body 32, it comes into contact with the object to be cleaned and cleans the object. Specifically, the wire 34 according to the present embodiment is formed of a string-like body (string-like member) having flexibility and flexibility. Since this wire 34 is not self-sustaining, when the rotating body 32 stops rotating, the part that is not connected to the rotating body 32 (referred to as the non-connected part) is -Z due to the action of gravity. hanging in the direction. On the other hand, when the rotating body 32 rotates, the wire 34 is subjected to centrifugal force, and the unconnected portion of the wire 34 is positioned outward in the radial direction of the rotating body 32 (in this embodiment, the unconnected portion of the wire 34 is (The connection will now be located approximately horizontally.) Then, the wire 34 removes foreign matter (soot, dust, etc.) adhering to the surface of the object to be cleaned by stripping off foreign matter (soot, dust, etc.) when at least a part of the unconnected part of the wire 34 comes into contact with the object to be cleaned. Remove. In this way, the wire 34 thoroughly cleans the object to be cleaned.

The "length in the radial direction of the rotating body 32" of the wire 34 may be a length that allows the wire 34 to come into contact with the object to be cleaned when the rotating body 32 rotates, and its specific value is not particularly limited. It's not something you can do. The length of the wire 34 may be appropriately set in consideration of the distance between the object to be cleaned and the rotating body 32, etc.

Further, the specific material of the wire 34 is not particularly limited, and for example, a metal or a non-metal may be used as the material of the wire 34. As the metal, for example, a metal containing iron, copper, aluminum, or the like as a main component may be used. As the nonmetal, for example, a material containing polyamide or the like as a main component may be used.

Note that by using a material for the wire 34 that is less hard than the object to be cleaned (pipes in this embodiment), damage to the object to be cleaned by the wire 34 can be suppressed to a small level.

Further, the surface texture of the wire 34 is not particularly limited, and may be a "smooth surface texture" having no unevenness, or a "non-smooth surface texture" having unevenness. Note that cleaning with the wire 34 can be performed more effectively when the surface of the wire 34 is non-smooth than when it is smooth.

Furthermore, the shape of the wire 34 is not limited to the loop shape as in this embodiment. For example, the wire 34 may have only one end connected to the blade 37 and the other end not connected to the blade 37. Also in this case, the wire 34 can clean the object to be cleaned because the portion of the wire 34 that is not connected to the rotating body 32 comes into contact with the object when the rotating body 32 rotates.

Note that when the wire 34 has a loop shape as in this embodiment, the cleaning range of the object to be cleaned by the wire 34 can be easily expanded compared to when the wire 34 does not have a loop shape. Thereby, cleaning efficiency can be improved.

Referring again to FIG. 2, as described above, the cleaning device system 20 according to the present embodiment includes a plurality of cleaning devices (cleaning devices 30-1a, 30-2a, 30-3a, 30-1b, 30-2b). , 30-3b). The cleaning device system 20 also includes a connecting header pipe 50 and a plurality of joints (joints 60a, 60b, 60c, 60d, 60e, 60f).

The connecting header pipe 50 is constituted by a pipe extending in the horizontal direction. A hose 151 is connected to the connecting header pipe 50. The upstream end of the hose 151 is connected to the fluid supply device 150 described above. The fluid pressure-fed from the fluid supply device 150 is supplied to the connecting header pipe 50 via this hose 151. The connecting header pipe 50 is provided with a discharge port 51a and a discharge port 51b. The discharge port 51a is located closer to the −X direction than the discharge port 51b.

The outlet 51a of the connecting header pipe 50 and the Z-direction end of the pipe 31-1a of the cleaning device 30-1a are connected by a joint 60a. The -Z direction end of the pipe 31-1a of the cleaning device 30-1a and the Z direction end of the pipe 31-2a of the cleaning device 30-2a are connected by a joint 60b. The -Z direction end of the pipe 31-2a of the cleaning device 30-2a and the Z direction end of the pipe 31-3a of the cleaning device 30-3a are connected by a joint 60c. The -Z direction side end of the pipe 31-3a is closed.

The outlet 51b of the connecting header pipe 50 and the Z-direction end of the pipe 31-1b of the cleaning device 30-1b are connected by a joint 60d. The -Z direction end of the pipe 31-1b of the cleaning device 30-1b and the Z direction end of the pipe 31-2b of the cleaning device 30-2b are connected by a joint 60e. The -Z direction end of the pipe 31-2b of the cleaning device 30-2b and the Z direction end of the pipe 31-3b of the cleaning device 30-3b are connected by a joint 60f. The -Z direction side end of the pipe 31-3b is closed.

The specific types of the plurality of joints are not particularly limited, and known joints for connecting two pipes can be used. Note that if detachable joints (for example, one-touch joints, etc.) are used as the plurality of joints, the cleaning device can be easily attached and detached. Therefore, in this embodiment, a detachable joint is used as an example of the plurality of joints.

Further, the cleaning device system 20 moves the cleaning devices (cleaning devices 30-1a to 30-3b) in the extending direction of the object to be cleaned (specifically, in the present embodiment, in the extending direction of the piping). It is equipped with a traveling device 70 for traveling. In this embodiment, the extending direction of the object to be cleaned is a horizontal direction, specifically a direction parallel to the Y-axis. The configuration of this traveling device 70 is as follows.

FIG. 6 is a front view of the traveling device 70. The traveling device 70 according to the present embodiment includes leg portions 71a, 71b, wheels 72a, 72b, a connecting portion 73, and locking plates (locking plates 74-1a, 74-2a, 74-1b, 74-2b). ).

The leg portion 71a is arranged closer to the −X direction than the leg portion 71b. The wheel 72a is arranged at the end of the leg 71a in the −Z direction. The wheel 72b is arranged at the −Z direction side end of the leg portion 71b. The connecting portion 73 connects the Z-direction side end portion of the leg portion 71a and the Z-direction side end portion of the leg portion 71b.

The wheels 72a run on the pipe 12-1a in the direction in which the pipe 12-1a extends. The wheels 72b run on the pipe 12-1c in the direction in which the pipe 12-1c extends.

The locking plates 74-1a and 74-2a are provided on the "surface facing the leg 71b" of the leg 71a. The locking plate 74-1a is located closer to the Z direction than the locking plate 74-2a. The locking plates 74-1b and 74-2b are provided on the "surface facing the leg 71a" of the leg 71b. The locking plate 74-1b is located closer to the Z direction than the locking plate 74-2b. The ground clearances of the locking plate 74-1a and the locking plate 74-1b are set to the same value. The ground clearance of the locking plate 74-2a and the locking plate 74-2b is also set to the same value.

The connecting header pipe 50 of the cleaning device system 20 is placed on the locking plates 74-1a and 74-1b or on the locking plates 74-2a and 74-2b. As an example, the connecting header pipe 50 according to this embodiment is placed on the locking plate 74-1a and the locking plate 74-1b.

In this way, with the connecting header pipe 50 placed on the locking plate 74-1a and the locking plate 74-1b, the traveling device 70 is moved in the extending direction of the object (piping) to be cleaned. , the cleaning device can be easily moved in the extending direction of the object to be cleaned.

In this embodiment, the number of stages of the locking plate is two, but the number of stages of the locking plate is not limited to this. The number of stages of the locking plate may be one, or three or more stages. However, as in this embodiment, the height of the cleaning device can be easily changed by having a plurality of stages of locking plates.

Next, an example of how the cleaning device system 20 according to the present embodiment is used will be described. Referring to FIG. 2 described above, when fluid is supplied from the fluid supply device 150 to the cleaning device system 20 via the hose 151, the fluid passes through the connecting header pipe 50 and then through the discharge ports 51a and 51b, respectively. and flows into each cleaning device. When fluid flows into each cleaning device, the rotating body 32 of the cleaning device rotates as described above with reference to FIGS. 3 and 4. During the rotation of the rotating body 32, fluid is injected outward in the radial direction of the rotating body 32 from the injection port 36 (the gap 37a between adjacent blades 37), and the wire 34 also rotates. As a result, purge cleaning by the fluid injected from the injection port 36 and cleaning by the wire 34 are performed simultaneously. Further, during cleaning, purge cleaning and smearing cleaning may be performed while the cleaning device is traveling in the extending direction of the object to be cleaned using the traveling device 70.

Note that the cleaning method according to the present embodiment is realized by the cleaning device system 20 described above. That is, in the cleaning method according to the present embodiment, the rotating body 32 is rotated relative to the pipe by passing fluid through the pipe of the cleaning device of the cleaning device system 20, and the rotating body 32 is removed from the rotating body 32. In this cleaning method, a rotating wire 34 is brought into contact with the object while jetting fluid outward in the radial direction of the wire 32 to clean the object.

Next, the effects of this embodiment will be explained. First, according to the present embodiment, the object to be cleaned can be cleaned using the wire 34 while jetting fluid outward in the radial direction of the rotating body 32 from the injection port 36 of the rotating body 32 . Thereby, purge cleaning using the fluid injected from the injection port 36 and cleaning using the wire 34 can be performed simultaneously. Therefore, compared to, for example, cases in which only smear cleaning can be performed at one time or only purge cleaning can be performed at a time, a wide range of the object to be cleaned can be simultaneously cleaned with less effort and in a simple manner. Further, since the wire 34 is formed of a string-like body, when the wire 34 comes into contact with the object to be cleaned, the wire 34 can easily deform to follow the shape of the object to be cleaned. In this respect as well, a wide range of objects to be cleaned can be cleaned simultaneously with a simple method without much effort. In addition, the wire 34 can be freely adjusted to fit the shape of the object to be cleaned and wrap around the object, and has a high bending effect, so it can scrape off foreign matter adhering to the object to be cleaned. High ability to remove. Therefore, since the wire 34 is highly effective in removing foreign matter adhering to the object to be cleaned, even foreign matter firmly adhering to the object can be cleaned.

Furthermore, according to the present embodiment, since piping (specifically, a plurality of pipings) is used as the object to be cleaned, purge cleaning and smearing cleaning can be performed simultaneously on a plurality of pipings. This makes it possible to improve the efficiency of the pipe cleaning work. As a result, the work burden on cleaning workers can be reduced. Thereby, the health condition of the cleaning workers can be maintained in good condition.

Further, according to the present embodiment, since the piping as the object to be cleaned is the piping of the incineration facility 10 (that is, the pipe for heat exchange), the cleaning work of the incineration facility 10 can be made more efficient. Thereby, the health condition of the cleaning worker can be maintained in good condition also in that the opportunity for the cleaning worker to be exposed to soot and dust etc. during the cleaning work can be reduced. In addition, this embodiment is specifically preferably applied to the heat exchange tube used for the incinerator, air preheater, etc. of the incineration facility 10.

Further, according to the present embodiment, fluid is used as a driving source for rotating the rotary body 32, and the fluid after being used for rotation of the rotary body 32 is effectively used as a “purge cleaning fluid”. ing. Thereby, the configuration of the cleaning device 30 can be simplified.

Further, according to the present embodiment, since the rotating body 32 is rotated by the fluid, the cleaning device can be self-cleaned by the fluid. Thereby, it is also possible to reduce maintenance costs for the cleaning device. In addition, the fluid can be used to purge and clean the groove 33a-1 and the injection port 36, as well as the inside of the pipe. It is also possible to maintain the purge function.

Further, according to the present embodiment, since the rotating body 32 includes the plurality of blades 37, the blades 37 can effectively receive pressure from the fluid injected from the nozzle hole 35 of the pipe. Thereby, the rotating body 32 can be effectively rotated by the fluid injected from the nozzle hole 35.

Further, according to the present embodiment, since the joints 60a, 60b, 60c, 60d, 60e, and 60f are provided to connect the respective pipes of the plurality of cleaning devices to each other, it is possible to easily connect the plurality of cleaning devices. can. Furthermore, since the cleaning device system 20 includes a plurality of cleaning devices, a wider range of objects to be cleaned can be cleaned compared to a case where the cleaning device system 20 includes only one cleaning device. Specifically, according to the present embodiment, a plurality of pipes (multiple rows and multiple stages of pipes) existing around a plurality of cleaning devices can be purged and cleaned. Therefore, high cleaning efficiency can be obtained.

Moreover, according to this embodiment, since the traveling device 70 is provided, the object to be cleaned can be cleaned while the cleaning device is traveling. Thereby, compared to the case where the traveling device 70 is not provided, a wider range of the object to be cleaned can be cleaned.

Moreover, according to this embodiment, cleaning can be performed without providing a scaffold for cleaning work. As a result, the cleaning device system 20 can be applied to, for example, objects to be cleaned where it is difficult to secure sufficient space for setting up scaffolding due to the high arrangement density of piping rows. A wide area can be cleaned at the same time.

Note that the cleaning work by the cleaning device system 20 described above is basically performed while the incineration facility 10 is stopped (specifically, while the operation of the incinerator of the incinerator 10 is stopped). As described above, according to the cleaning device system 20 according to the present embodiment, a wide range of objects to be cleaned can be cleaned at the same time (that is, the cleaning efficiency is high), so the cleaning frequency is lower than that of the conventional technology. (number of cleanings per unit year) can be easily increased. This makes it easy to maintain good performance of the incineration facility 10.

(Embodiment 2)
Next, a cleaning device system 20A and a cleaning method according to Embodiment 2 of the present invention will be described. The cleaning device system 20A according to this embodiment is used, for example, to clean the water pipe wall in the second chamber 11b of the incineration facility 10 shown in FIG. 1 described above.

FIG. 7 is a perspective view showing a part of the second chamber 11b of the incineration facility 10. The second chamber 11b is provided with a plurality of water tube walls (water tube walls 13a, 13b, 13c, 13d, and 13e). Each water pipe wall is constituted by a collection of a plurality of pipes. That is, in one water pipe wall, a plurality of pipes are arranged in a row. A virtual surface in contact with the surfaces of the plurality of pipes has a wall shape (a wall shape extending in a direction parallel to the Z axis).

In addition, in FIG. 7, the wall surface of the water tube wall 13a is parallel to the YZ plane. The wall surface of the water tube wall 13b is parallel to the XZ plane. The wall surface of the water tube wall 13c faces the wall surface of the water tube wall 13a. The water tube wall 13d and the water tube wall 13e are arranged in a space surrounded by the water tube walls 13a, 13b, and 13c. The ends of the water tube walls 13d and 13e in the −Z direction communicate with the connecting tube 14. A refrigerant passes inside these water tube walls. Furthermore, an inspection port 15a is provided in the water tube wall 13b. An inspection port 15b is also provided on the wall surface of the third chamber 11c adjacent to the second chamber 11b.

Combustion gas (GA) generated in the first chamber 11a passes through the inside of the second chamber 11b from the upper side to the lower side, and then flows into the third chamber 11c. At this time, heat exchange occurs between the combustion gas and the refrigerant on the water tube wall. Incidentally, soot dust (DU) contained in the combustion gas may adhere to such water pipe walls. The cleaning device 30A according to the present embodiment uses the water pipe wall as an object to be cleaned, as an example, and is used to clean and remove soot and dust adhering to the water pipe wall.

FIG. 8 is a perspective view showing a state in which the cleaning device system 20A according to the present embodiment is applied to the incineration facility 10. The cleaning device system 20A according to this embodiment is used by being installed on a scaffold 160, for example. Specifically, this scaffold 160 is a stand for making it easier to install the cleaning device system 20A (this scaffold 160 is not a so-called high-place scaffold). Fluid is supplied to the cleaning device 30A from a fluid supply device 150 via a hose 151. As this fluid, the same fluid as in the first embodiment described above can be used. The fluid supply device 150 according to this embodiment is arranged outside the third chamber 11c, for example. Therefore, the hose 151 according to the present embodiment enters the second chamber 11b after passing through the inspection port 15b and entering the third chamber 11c, and is connected to the -Z direction side end of the pipe 31-1c. .

FIG. 9 is a perspective view of a cleaning device system 20A according to this embodiment. The cleaning device system 20A includes a cleaning device 30A, a fixing table 90, and a vibration suppressing device 100. Details of the cleaning device 30A will be described later.

The fixing base 90 is a member that fixes the pipe of the cleaning device 30A to the scaffold 160. Specifically, the fixing base 90 according to the present embodiment fixes the -Z direction side end of the pipe of the cleaning device 30A to the scaffold 160.

Here, the pipe of the cleaning device 30A according to this embodiment is divided into a plurality of parts. Specifically, the pipe of the cleaning device 30A is divided into, for example, pipes 31-1c, 31-2c, 31-3c, and 31-4c. Pipe 31-2c is arranged on the Z-direction side of pipe 31-1c, pipe 31-3c is arranged on the Z-direction side of pipe 31-2c, and pipe 31-4c is arranged on the Z-direction side of pipe 31-3c. It is located in The fluid that has flowed into the pipe 31-1c via the hose 151 passes through the pipe 31-1c, the pipe 31-2c, the pipe 31-3c, and the pipe 31-4c in this order. The pipes 31-2c and 31-3c are provided with nozzle holes 35, as in the first embodiment described above. A plurality of nozzle holes 35 are provided in the extending direction of the pipe 31. The fluid passing through the pipe 31 is injected toward the outside of the pipe 31 from this nozzle hole 35 .

In this embodiment, the end of the pipe 31-4c in the Z direction is closed to the extent that a large amount of fluid inside the pipe 31-4c can be prevented from leaking to the outside from this end. A hole is provided that is large enough to allow the moving wire 82 of the moving device 80 to be inserted therethrough. Referring again to FIG. 8, a protection tube 152 is provided near the inspection port 15a. A portion of the moving wire 82 passes through the inside of this protection tube 152. This protection tube 152 prevents the moving wire 82 from coming into direct contact with the inspection port 15a.

As shown in FIG. 9, the deflection suppressing device 100 is a device that suppresses the deflection of the pipe of the cleaning device 30A. Specifically, the vibration suppressing device 100 according to the present embodiment includes, as an example, a fitting member 101 fitted to a pipe, and an engaging member that engages the pipe and the object to be cleaned (water pipe wall). (engaging members 102a, 102b, 102c, 102d). By engaging the engaging member with the pipe and the object to be cleaned, swinging of the pipe in the direction toward the object to be cleaned is suppressed.

Specifically, one ends of the engaging members 102a, 102b, 102c, and 102d are connected to the fitting member 101. Furthermore, wheels 103 are provided at the other ends of the engaging members 102a, 102b, 102c, and 102d, respectively, according to this embodiment. The engaging member 102a extends in the -Y direction starting from the end on the pipe 31 side. The engaging member 102b extends in the -X direction starting from the end on the pipe 31 side. The engaging member 102c extends in the Y direction starting from the end on the pipe 31 side. The engagement member 102d extends in the X direction starting from the end on the pipe 31 side. In this way, the engagement members of the shake suppression device 100 according to the present embodiment extend in four directions.

In the case of the example shown in FIG. 8, in the vibration suppressing device 100, the engaging member 102b engages with the water pipe wall 13a and the pipe. Specifically, the engaging member 102b indirectly engages with the water tube wall 13a and the pipe via the wheel 103 and the fitting member 101. Similarly, in the vibration suppressing device 100, the engaging member 102c indirectly engages with the water pipe wall 13b and the pipe. This effectively suppresses the pipe from swinging toward the water pipe wall 13a or the water pipe wall 13b.

Note that the vibration suppressing device 100 can also be configured without the wheels 103. However, since the shake suppressing device 100 includes the wheels 103, it is possible to effectively suppress the engagement member from coming into direct contact with the object to be cleaned. This allows the cleaning worker to easily move the pipe.

Further, the engagement member may have a spring structure that can expand and contract a predetermined length in the longitudinal direction of the engagement member. To give an example of this, for example, a part of the engaging member may be constituted by a spring. According to this configuration, the engaging member can expand and contract by a predetermined length in the longitudinal direction, so even if the distance between the pipe and the object to be cleaned is not uniform, the wheel 103 can be easily attached to the water pipe wall. It can be brought into contact with the Thereby, the shake suppressing effect of the shake suppressing device 100 can be more effectively exerted.

FIG. 10 is a front view of the cleaning device 30A according to this embodiment. FIG. 11 is a sectional view taken along line A2-A2 in FIG. FIG. 12(A) is a sectional view taken along line A3-A3 in FIG. Note that in FIG. 12(A), illustrations of a bearing 39 and a magnetic force generator 81, which will be described later, are omitted. FIG. 12(B) is an enlarged view of portion B3 in FIG. 12(A).

As shown in FIG. 10, the cleaning device 30A according to the present embodiment includes pipes (pipes 31-1c, 31-2c, 31-3c, 31-4c), a rotating body 32, a connecting member 38c, and a wire 34. and a bearing 39.

The rotating body 32 is arranged on the outside in the radial direction of the pipe. The rotating body 32 is fitted into the pipe so as to be rotatable relative to the pipe. Specifically, the rotating body 32 according to this embodiment includes a plurality of blades 37. The configuration of this blade 37 is the same as that of the first embodiment described above, so a description thereof will be omitted. The connecting member 38c connects the −Z direction side ends of the plurality of blades 37. As a result, the blade 37 and the connecting member 38c rotate together. As shown in FIG. 11, in this embodiment, the Z-direction side ends of the plurality of blades 37 are connected to the outer bearing portion 39b of the bearing 39. Thereby, the blade 37 and the outer bearing portion 39b rotate as one.

As shown in FIG. 10, the wire 34 according to this embodiment is different from the first embodiment described above in that the wire 34 is connected to the outer peripheral surface of the buoyancy vane 40. Except for this point, the configuration of the wire 34 is the same as that in Embodiment 1, so a detailed explanation of the wire 34 will be omitted. Although this will be described later, the buoyancy vane 40 rotates together with the rotating body 32. Therefore, similarly to Embodiment 1, the wire 34 according to the present embodiment rotates together with the rotating body 32 when the rotating body 32 rotates and comes into contact with the cleaning target, so that the wire 34 can clean the cleaning target. can.

Note that the wire 34 may be connected to a location where the wire 34 can rotate together with the rotating body 32 when the rotating body 32 rotates, and may be connected to the rotating body 32 or may be connected to the rotating body 32 integrally. It may also be connected to a member that rotates. Note that in this embodiment, the wire 34 is connected to the buoyancy vane 40 (a member that rotates integrally with the rotating body 32), but the wire 34 is not limited to this. To give another example, the wire 34 may be connected to, for example, the blade 37 of the rotating body 32, as in the first embodiment.

As shown in FIG. 11, the bearing 39 is constituted by a rolling bearing. Specifically, the bearing 39 according to this embodiment includes the aforementioned outer bearing portion 39b, as well as an inner bearing portion 39a and rolling elements 39c. The inner bearing portion 39a is fitted into the pipe so as to be movable relative to the pipe in the direction in which the pipe extends. The aforementioned outer bearing portion 39b is arranged radially outward of the inner bearing portion 39a via the rolling elements 39c. The outer bearing portion 39b can rotate relative to the inner bearing portion 39a.

As shown in FIG. 12(B), in this embodiment as well, similarly to Embodiment 1, the rotating body 32 is driven by the fluid (FL) injected from the nozzle hole 35 of the pipe, and rotate relative to each other. Then, the fluid after being injected from the nozzle hole 35 is injected outward in the radial direction of the rotating body 32 from the gap 37a (that is, the injection port 36) between the blades 37. Further, when the rotating body 32 rotates, the wire 34 rotates together with the rotating body 32 and comes into contact with the object to be cleaned. Thereby, the wire 34 cleans the object to be cleaned.

Further, as shown in FIG. 11, the cleaning device system 20A according to the present embodiment includes a moving device 80 that moves the rotating body 32 in the extending direction of the pipe. The moving device 80 according to this embodiment includes a magnetic force generator 81 and a moving wire 82. Furthermore, the moving device 80 according to the present embodiment also includes the buoyancy blades 40 as some of its components.

The magnetic force generator 81 is made of a substance that generates magnetic force. Although the specific type of the magnetic force generator 81 is not particularly limited, in this embodiment, a magnet is used as an example of the magnetic force generator 81. As this magnet, a permanent magnet, an electromagnet, etc. can be used. Moreover, the magnetic force generator 81 according to this embodiment is arranged inside the pipe 31, as an example.

The moving wire 82 is connected to the magnetic force generator 81 . The magnetic force generator 81 is suspended by a moving wire 82. The end of the moving wire 82 on the side opposite to the magnetic force generating body 81 is arranged in a chamber different from the second chamber 11b. With this configuration, the cleaning worker is in a room different from the second room 11b and can remotely control the magnetic force generator 81 in the pipe by winding up and down the moving wire 82. Note that, for example, the moving wire 82 can be wound up and down using a manual or electric reel.

Further, the inner bearing portion 39a of the bearing 39 has the property of being attracted by magnetic force. Specifically, the inner bearing portion 39a according to this embodiment is made of a ferromagnetic material. Thereby, the inner bearing portion 39a can be moved in the extending direction of the pipe by being attracted by the magnetic force of the magnetic force generator 81. By moving the inner bearing portion 39a in this manner, the rotating body 32 can also move in the extending direction of the pipe. As described above, the moving device 80 according to the present embodiment uses the magnetic force generated by the magnetic force generator 81 to move the rotating body 32 in the extending direction of the pipe.

The outer bearing portion 39b and the rolling elements 39c of the bearing 39 may be made of a ferromagnetic material, or may be made of a non-ferromagnetic material (a material that is not attracted by magnetic force). However, if the outer bearing portion 39b and the rolling elements 39c are made of a non-ferromagnetic material, it is possible to prevent the rotation of the outer bearing portion 39b and the rolling elements 39c from being influenced by the magnetic force from the magnetic force generator 81. can.

As shown in FIG. 11, the buoyancy vane 40 is connected to the outer peripheral surface of the outer bearing portion 39b. Thereby, the buoyancy blade 40 rotates together with the blade 37 (rotating body 32). The buoyancy vanes 40 are configured to generate buoyancy when rotated. Thereby, the rotating body 32 can move in the Z direction (upward) using the buoyancy generated by the buoyancy vanes 40. Furthermore, when the rotation of the rotating body 32 slows down, and as a result, the buoyancy generated by the buoyancy blades 40 becomes smaller, the rotating body 32 can also move in the -Z direction (downward). In this way, the moving device 80 according to the present embodiment moves the rotating body 32 by also utilizing the buoyancy generated by the buoyancy blades 40.

Note that the moving device 80 may include only one of the magnetic force generator 81 and the buoyancy blade 40. However, when the moving device 80 includes both the magnetic force generator 81 and the buoyancy blade 40, the rotating body 32 can be moved more easily than when the moving device 80 includes either one of them.

Next, an example of how the cleaning device system 20A according to this embodiment is used will be described. Referring to FIG. 8 described above, when the fluid is supplied from the fluid supply device 150 to the cleaning device system 20A via the hose 151 and the fluid flows into the cleaning device 30A, the rotating body 32 of the cleaning device 30A is rotated. Rotate. During the rotation of the rotating body 32, fluid is injected outward in the radial direction of the rotating body 32 from the injection port 36 (the gap 37a between adjacent blades 37), and the wire 34 also rotates. As a result, purge cleaning by the fluid injected from the injection port 36 and cleaning by the wire 34 are simultaneously performed on the water tube wall.

Further, during cleaning, purge cleaning and smearing cleaning can be performed while moving the rotating body 32 in the extending direction of the pipe using the moving wire 82 of the moving device 80. In this case, during cleaning, the rotary body 32 may be moved from the lower end of the pipe to the upper end while the rotary body 32 is temporarily stopped at a predetermined location in the extending direction of the pipe (for example, stopped for about 30 seconds). good. Moreover, in the case of this embodiment, since the buoyancy blades 40 are provided and buoyancy is generated by the buoyancy blades 40 when the rotating body 32 rotates, the rotating body 32 can be easily moved.

Note that in the embodiment described above, the cleaning device system 20A includes one cleaning device 30A, but the configuration is not limited to this. The cleaning device system 20A may include a plurality of cleaning devices 30A.

Further, the cleaning method according to the present embodiment is realized by the cleaning device system 20A described above. That is, in the cleaning method according to the present embodiment, the rotating body 32 is rotated relative to the pipe by passing fluid through the pipe of the cleaning device system 20A, and the diameter of the rotating body 32 is In this cleaning method, a rotating wire 34 is brought into contact with an object to be cleaned while jetting fluid outward in a direction to clean the object to be cleaned.

Next, the effects of this embodiment will be explained. In this embodiment, as in the first embodiment, the object to be cleaned is cleaned by the wire 34 while jetting fluid outward in the radial direction of the rotating body 32 from the injection port 36 of the rotating body 32. I can do it. As a result, similarly to the first embodiment, a wide range of objects to be cleaned can be simultaneously cleaned using a simple method without much effort.

Furthermore, according to the present embodiment, since the water pipe wall (specifically, a plurality of water pipe walls) is used as the object to be cleaned, purge cleaning and wiping cleaning are simultaneously performed on the plurality of water pipe walls. It can be carried out. This makes it possible to improve the efficiency of cleaning the water pipe wall. As a result, the work burden on cleaning workers can be reduced. This also allows cleaning workers to maintain good health.

Furthermore, according to the present embodiment, since the water pipe wall of the incineration facility 10 (i.e., the pipe for heat exchange) is used as the water pipe wall, it is possible to improve the efficiency of the cleaning work of the incineration facility 10. . Thereby, the health condition of the cleaning worker can be maintained in good condition also in that the opportunity for the cleaning worker to be exposed to soot and dust etc. during the cleaning work can be reduced. In addition, this embodiment is specifically preferably applied to the heat exchange tube used for the incinerator, air preheater, etc. of the incineration facility 10.

Further, in this embodiment as well, fluid is used as a driving source for rotating the rotary body 32, and the fluid after being used for the rotation of the rotary body 32 is effectively used as a "purge cleaning fluid". Therefore, the configuration of the cleaning device 30A can be simplified.

Also in this embodiment, since the rotating body 32 is rotated by fluid, the cleaning device can be self-cleaned by the fluid. Thereby, maintenance costs for the cleaning device can be reduced. Furthermore, in this embodiment as well, the fluid can be used to purge and clean the groove 33a-1 and the injection port 36, as well as the inside of the pipe. It is also possible to maintain the function of purging fluid toward the outside.

Further, according to the present embodiment, since the moving device 80 is provided, the object to be cleaned can be cleaned while moving the rotating body 32 in the extending direction of the pipe. Thereby, compared to the case where the moving device 80 is not provided, a wider range of the object to be cleaned can be cleaned. Moreover, according to this configuration, even if the height of the object to be cleaned is high, the rotating body 32 can be moved from below to above the object to be cleaned. Furthermore, since there is no need for high-altitude scaffolding during cleaning, the cleaning period can be shortened, and the labor of cleaning workers can also be reduced, which is economical. Moreover, since the cleaning period can be shortened, there is no need to stop the incineration facility 10 for a long period of time. Thereby, the number of times of cleaning per year can be increased without impairing economic efficiency (for example, cleaning can be performed more than several times per year). Specifically, the number of times of simple cleaning and periodic cleaning can be increased. Furthermore, since the number of times of cleaning can be increased, high cooling efficiency and heat exchange efficiency can also be maintained.

Further, according to the present embodiment, since the moving device 80 moves the rotating body 32 using the magnetic force generated by the magnetic force generator 81, the rotating body 32 can be moved with a simple configuration.

Further, according to the present embodiment, since the moving device 80 moves the rotating body 32 by also utilizing the buoyancy generated by the buoyancy vanes 40, the rotating body 32 can be easily moved.

Further, according to the present embodiment, since the swing suppressing device 100 is provided, it is possible to effectively suppress the pipe from swinging in the direction toward the object to be cleaned. Thereby, cleaning work can be easily performed.

In addition, in the first and second embodiments described above, if only smear cleaning is performed, the cleaning device may be configured not to eject fluid. That is, in this case, the cleaning device only needs to be configured so that the fluid after rotating the rotary body 32 is not jetted outward in the radial direction of the rotary body 32. In this case, when the rotating body 32 rotates, the cleaning device performs only cleaning using the wire 34 without performing purge cleaning using the fluid. However, as described above, it is preferable for the cleaning device to perform not only smear cleaning but also purge cleaning, since a wide range of the object to be cleaned can be cleaned at the same time.

In addition, in this embodiment, the cleaning device system 20A can also be configured without the scaffold 160. Even in this case, the same effects as described above can be achieved.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to such specific embodiments, and various modifications and variations can be made within the scope of the gist of the present invention as described in the claims. Changes are possible.

For example, in the first and second embodiments, a predetermined part of the incineration facility 10 is used as the object to be cleaned, but the object to be cleaned in the first and second embodiments described above is not limited to the incineration facility 10. A predetermined part of a mechanical device other than the incineration facility 10, a predetermined part of a structure, etc. can be used. Further, when a predetermined portion of the incineration facility 10 is used as the object to be cleaned, the predetermined portion is not limited to those exemplified in Embodiment 1 and Embodiment 2. For example, a refractory wall surface of the incineration facility 10 can also be used as the object to be cleaned.

Further, in the first and second embodiments, the rotary body 32 has a plurality of blades 37, but the rotary body 32 is not limited to this configuration. To give another example, a cylindrical member (cylindrical member) may be used as the rotating body 32 instead of the plurality of blades 37.

A slit or hole serving as an injection port 36 is provided on the outer peripheral surface of this cylindrical member. By adjusting the opening direction of the injection port 36 (for example, by slightly directing the opening direction of the injection port 36 toward the tangential direction of the outer circumferential surface of the cylindrical member), the cylindrical member can be configured such that the fluid is injected from the injection port 36. It is possible to rotate relative to the pipe by utilizing the change in momentum when moving. Further, the fluid that has been subjected to the rotation of the cylindrical member is then injected radially outward from the injection port 36. Even when such a rotating body is used, purge cleaning and cleaning can be performed at the same time.
