Description

TECHNICAL FIELD The present invention relates to an eliminator that removes mist in airflow, and an air cleaning device equipped with the eliminator.

Conventionally, for example, an eliminator described in Patent Document 1 is provided with a plurality of elements, and the elements include a curved surface portion, an extending surface portion extending from the downstream end of the curved surface portion, and a downstream end of the extending surface portion. It is equipped with a gutter section. The gutter portion is made to protrude from the surface of the elongated surface portion so that when the elongated surface portion is extended as it is, the interior of the gutter portion is divided by the virtual extended surface.

Furthermore, in the water droplet separation device described in Patent Document 2, a plurality of water droplet separation plates are arranged in parallel at predetermined intervals, and the outer surface of the windward side slope part and/or the inner surface of the leeward side slope part of the water droplet separation plate is arranged in parallel at predetermined intervals. A plurality of parallel protrusions are provided in each intermediate portion in the width direction, which are continuous in the length direction. The protrusions have a triangular cross section and are arranged at a pitch greater than the width of the bottom surface.

Further, the eliminator device described in Patent Document 3 is provided in a flow path through which airflow flows from the bottom to the top, and includes an eliminator for low wind speeds and an eliminator for high wind speeds provided above the eliminator for low wind speeds. are doing. The eliminator for low wind speeds includes a net-like or cloth-like capture member having a large number of small openings through which airflow passes, and the capture member has a plurality of alternating upward peaks and downward valleys. The eliminator for high wind speeds is made up of multiple bent plates connected at a predetermined pitch, and a curved flow path is formed between the bent plates. In the flow path, particulates contained in the gas are captured by inertial collision. . The eliminator for low wind speeds is sloped so that one end in the longitudinal direction of the peaks and valleys is higher than the other end, and the eliminator for high wind speed is sloped so that one end in the longitudinal direction perpendicular to the pitch direction of the bending plate is inclined to the other end. It is sloped so that it is higher than the end.

As described above, the high wind speed eliminator uses inertial collision, that is, inertial force to cause mist to collide with a wall surface and capture it. Inertial force acts on the mist moving with the airflow, and the higher the airflow speed and the greater the mass of the mist, the greater the inertial force.

When a high-speed airflow flows through the curved flow path of a high-speed eliminator, the mist moving along with the high-speed airflow will move in the inertial direction without following the change in the path of the airflow and separate from the airflow. It comes off, collides with the wall of the eliminator flow path, and is captured.

When a low-speed airflow flows through a curved channel, the mist that moves along with the low-speed airflow does not deviate from the airflow and flows along the curved channel with the airflow. Therefore, when removing mist in low wind speed airflow, place an eliminator for low wind speed across the direction of travel of the airflow. It is captured by inertial collision. The low-speed airflow with weak carrying power will not entrain the mist again. When a high wind speed airflow passes through a low wind speed eliminator, the mist that has inertially collided with the mist is in the airflow, so it is entrained again by the high wind speed airflow with a strong carrying force.

Since the inertial force acting on ultrafine particulate mist, which has a small mass, is weak, it is difficult to remove ultrafine particulate mist contained in high wind speed airflow with an eliminator. It may contain ultrafine mist.

When the humidity in the in-machine environment on the downstream side of the eliminator in the air purifying device is high, the surrounding water vapor gathers around the ultrafine mist as a nucleus, and the particle size of the mist increases and adheres to the wall surface of the in-machine. Ultrafine mist can be prevented from becoming enlarged at a relative humidity of 30% or less, begins to enlarge at a relative humidity of 30 to 40%, and becomes particles with a diameter of about 0.1 mm at a relative humidity of 50 to 60%. In air purifiers, the mist contains chemical components, which can cause rust.

In addition, scale and slime (viscous substances) tend to adhere to the element, which clogs the flow path and impairs the mist removal function of the eliminator, resulting in a shortened product life. For this reason, it is usually necessary to replace the eliminator every six months.

Through analysis, the present inventors determined an eliminator flow path structure that is optimal for removing mist from high-velocity airflow.

FIG. 11 shows the analysis results. (a) shows analysis model 1, which is a pattern in which an eliminator 901 is made up of elements 900 bent in a substantially doglegged shape, and the gap width of the flow path 902 between the elements is set wide. (b) shows analysis model 2, which is a pattern in which an eliminator 901 is made up of elements 900 bent in a substantially doglegged shape, and the gap width of the flow path 902 between the elements is set narrow. (c) shows analysis model 3, which is a pattern in which an eliminator 904 is made up of elements 903 bent in a substantially W-shape, and the gap width of the flow path 90905 between the elements is set wide. (d) shows analysis model 4, which is a pattern in which an eliminator 904 is made up of elements 903 bent in a substantially W-shape, and the gap width of the flow path 905 between the elements is set narrow.

In FIG. 11, the captured mist is stippled in channels 902 and 905. In analytical models 1 and 3 in which the gap width between the channels 902 and 905 is wide, the mist reaches the central region of the channels 902 and 905 between the elements, and the mist flows to the downstream region. Furthermore, the more complicated the curved channels 902 and 905 are, the more complex the curved channels 902 and 905 are. Also, a lot of mist is captured in the upstream area of the flow path 905, and less mist reaches the downstream area.

On the other hand, in analysis models 2 and 4 with narrow channel widths, most of the mist is captured in the upstream areas of the channels 902 and 905 between the elements, and only a small amount of mist reaches the central region of the channels 902 and 905. .

The above analysis shows that the curved shape of the channels 902, 905 and the gap width between the channels 902, 905 are factors that strongly affect mist removal.The more complicated the curved shape of the channels 902, 905, the more It has been found that the narrower the gap width between the channels 902 and 905, the higher the mist removal performance.

However, the more complicated the curved shape of the flow paths 902, 905, the more the gap between the flow paths 902, 905 formed between the thin plate blade-like elements 900, 903 constituting the eliminator. The narrower the width, the higher the flow path resistance against high wind speeds. Further, if the flow path shape is deformed due to deformation of the elements 900, 903, etc., it is difficult to ensure good air permeability.

Conventional eliminators use long elements that are molded and cut into appropriate lengths to match the shape of the target model, and the ends of the elements are left open.

For this reason, the thin plate vane-like elements have low rigidity against airflow, which poses a problem in maintaining the gap width between the elements set based on the analysis results.

An eliminator has multiple elements housed within a frame, but since the open ends of the elements face the inner surface of the frame, the elements may be deformed by contact when inserted into the frame. . Moreover, the mist captured by the element flows out from the open end through the frame and into the inner surface of the air purifier body, instead of passing through the original exhaust path, causing rust.

The present invention solves the above-mentioned problems, and makes it possible to reliably maintain the gap width of the flow path between elements at the set width, facilitate maintenance, and maintain good mist removal performance. The purpose is to provide an eliminator and air purifier that can be kept for a long time.

In order to solve the above problems, the eliminator of the present invention includes a frame body through which airflow flows from one opening to the other opening, and a plurality of thin plate-like elements arranged in the frame body in a direction transverse to the flow of the airflow. , has an air flow path provided between the elements, and the element has a bent part that is bent in a cross section along the element arrangement direction and in the direction from one opening of the frame to the other opening. and a side wall closing both ends of the bent portion facing the inner surface of the frame.

In the eliminator of the present invention, the element has an inner space surrounded by a bent portion and both side walls closing both ends of the bent portion, and an open opening facing the element arrangement direction, and both side walls of the element face the open opening. Adjacent elements are characterized in that the other element enters the inner space of one element through an open opening and overlaps in the element arrangement direction.

In the eliminator of the present invention, the element has a contact part that defines the gap width of the flow path between adjacent elements, and a fitting part that connects the elements, and the contact part has an inner surface formed inside the element. Elements that have an abutment surface and an outer abutment surface formed on the outside of the element and that overlap in the element arrangement direction are in contact with the inner abutment surface of one element and the outer abutment surface of the other element, creating a gap between the elements. The fitting part that forms the flow path consists of a fitting recess formed on the inner abutment surface of the element toward the outside of the element, and a fitting convexity formed on the outer abutment surface of the element toward the outside of the element. , for elements that overlap in the element arrangement direction, the fitting recess of one element and the fitting convex part of the other element fit together to connect the elements, or the fitting part is on the inner abutment surface of the element. Consisting of a fitting protrusion formed towards the inside of the element and a fitting recess formed towards the inside of the element on the outer contact surface of the element, the elements that overlap in the element arrangement direction have a fitting protrusion of one element and a fitting recess formed towards the inside of the element. The fitting recess of the other element fits together to connect the elements.

The air purifying device of the present invention includes a housing having a ventilation path through which an airflow of air to be humidified flows, a spray nozzle that sprays water to the air to be humidified flowing through the ventilation path, and a housing provided on the downstream side of the spray nozzle in the flow direction of the airflow. The present invention is characterized in that it includes an eliminator to be disposed, and the eliminator is any one of the above-mentioned eliminators.

As described above, according to the present invention, the element has a side wall, and the side wall closes both ends of the bent portion facing the inner surface of the frame body, and functions as a structural member that suppresses deformation of the bent portion. By preventing this, the gap width of the flow path between the elements can be maintained reliably, and the mist removal performance of the eliminator can be extended, and by ensuring the rigidity of the element, it is possible to respond to higher airflow speeds.

Further, the side wall prevents the mist captured by the eliminator from flowing out from the element through the inner surface of the frame to the wall surface inside the machine, and can prevent rusting inside the machine, the fan, etc.

Elements are connected to each other by the fitting part without using adhesives, and the structure allows for separation and recombination of elements, so scale and slime (mucus-like substances) that adhere to the elements can be removed. This allows for easy maintenance and extends the life of the eliminator's mist removal function. Further, due to the presence of the abutting portion, the separated element can be easily connected to the gap width of the flow path between the original elements.

The high wind speed eliminator 32 has a plurality of thin plate-like elements 45 arranged at a predetermined pitch P along the direction crossing the airflow of the air 8 to be sterilized inside a frame 46. A flow path 49 is provided between the elements, through which the airflow of the air 8 to be sterilized flows from the opening 47 on one side (lower side) to the opening 48 on the other side (upper side).

There are two types of elements 45, a first element 451 shown in FIG. 1 and a second element 452 shown in FIG. and explain.

The element 45 is bent in a substantially dogleg shape in a cross section along the element arrangement direction, and closes a bent portion 45a having a mountain-like outer shape and both ends of the bent portion 45a facing the inner surface of the frame 46. It has a side wall 45b. The element 45 has an inner space 45c surrounded by a bent portion 45a and both side walls 45b, and an open opening 45d facing the element arrangement direction, and the both side walls 45b of the element 45 are inclined outward toward the open opening 45d. There is. Further, the bent portion 45a is provided with a plurality of parallel grooves 45e that are recessed from the outside of the element toward the inner space 45c. The groove 45e is inclined from the peak 45f of the element 45 toward the opening 45d.

Adjacent elements 45, that is, the first element 451 and the second element 452, are arranged such that, for example, the other second element 452 enters the inner space 45c of one first element 451 through the opening 45d, and the other second element 452 enters the inner space 45c of one first element 451, and overlapping.

The element 45 has a contact part 61 that defines the gap width of the flow path 49 between adjacent elements, and a fitting part 62 that couples the elements 45 together.

Therefore, in the elements 45 that overlap in the element arrangement direction, for example, the inner abutment surface 63 of one first element 451 and the outer abutment surface 64 of the other second element 452 abut, creating a flow path between the elements. is formed, and the width of the flow path 49 is maintained at an optimal value determined by analysis, experiment, etc.

The fitting portion 62 includes a fitting recess 67 formed in an inner contact surface 63 of the element 45 in a concave shape toward the outside of the element, and a fitting recess 67 formed in an outer contact surface 64 of the element 45 in a convex shape toward the outside of the element.

Next, a pan 510 is arranged below the wind tunnel 509 to catch the disinfectant solution descending from the wind tunnel 509, and the eliminator 507, media 506, wind tunnel 509, and pan 510 can be removed from the housing 500 during maintenance. The media 506 is attached and detached from the front side of the wind tunnel 509. Furthermore, by lifting the eliminator 507 during operation, it is possible to check the spray state of the disinfectant solution.

A circulation tank 54 is provided below the pan 510, and the circulation tank 54 receives and stores the disinfectant solution descending from the purification air passage 52 and the disinfectant solution flowing from the pan 510. A relay tank 541 is provided inside the circulation tank 54, and a descending liquid guide plate 542 is provided to cover the relay tank 541.

A circulation system 55 is disposed between the circulation tank 54 and the spray device 53, and the circulation system 55 has a circulation pump 550 to supply the disinfectant solution in the circulation tank 54 to the spray device 53.

In the circulation system 55, a circulation pump 550 that also serves to spray and discharge the disinfectant solution is located below the circulation tank 54, and a three-way switching valve 551 and a check valve 552 are interposed downstream of the circulation pump 550. A drainage system 567 branches from the three-way switching valve 551, and by switching the three-way switching valve 551, one circulation pump 550 can be used to circulate and discharge the disinfectant solution.

The drug supply system 56 that supplies slightly acidic electrolyzed water, which is a undiluted disinfectant solution at the concentration at the time of generation, includes a generation device 561 that generates slightly acidic electrolyzed water, a water supply system 562 that supplies water to the generation device 561, and a water supply system 562. A dilution water supply system 563 that branches off from and supplies dilution water to the circulation tank 54, a relay tank 541, and a dilution water supply system 563 that supplies slightly acidic electrolyzed water from the generator 561 to the circulation tank 54 via the relay tank 541 and the relay tank 541. A preparation supply section 564 that supplies a large flow rate, and a replenishment supply section 566 that is interposed with a relay pump 565 that drips and supplies slightly acidic electrolyzed water from the relay tank 541 to the circulation tank 54 at a small replenishment flow rate. There is.

The bottom surface of the relay tank 541 slopes downward from one side edge 541a corresponding to the opening 564a of the preparation supply section 564 toward the other side edge 541b, and then slopes upward through the bottom portion 541c. . The other side edge 541b is located at a lower position than the one side edge 541a, forms an overflow edge, and a replenishment supply part 566 is connected to the lowest part 541c.

A three-way switching valve 564b is interposed in the dispensing supply section 564, and an external outlet 564c branches off from the three-way switching valve 564b, and a water supply port 564d of the external outlet 564c is provided on the side of the housing 500. be.

Inside the circulation tank 54, a lower limit liquid level gauge 54a, a middle level liquid level gauge 54b, and an upper limit liquid level gauge 54c are provided at positions corresponding to respective set liquid levels. A control device 700 that controls the operation of the air purifying device is provided on the front side of the door body 501.

The control device 700 has a functional circuit responsible for a normal operation mode, a preparation operation mode, and a cleaning operation mode, and repeats batch operation in which one cycle is a normal operation mode and a preparation operation mode, and performs a normal operation mode and a preparation operation mode. The cleaning operation mode is executed after the cycle with the mode is performed multiple times.

The operation of the above configuration will be explained below.

Here, the normal operation mode will be explained. The drug supply device 56 drips and supplies slightly acidic electrolyzed water from the relay tank 541 to the circulation tank 54 via the replenishment supply unit 566 using a relay pump 565 at a small replenishment flow rate, for example, 0.05 L/min. The effective chlorine concentration of the disinfectant solution in the circulation tank 54 is maintained at 0.1-10 mg/L, and the disinfectant solution in the circulation tank 54 is maintained at a diluted concentration suitable for sterilization.

In this state, the circulation pump 550 supplies the disinfectant solution in the circulation tank 54 to the spraying device 53, and the spraying device 53 A disinfectant solution whose concentration has been adjusted in the circulation tank 54 is sprayed from the spray nozzle 531 . The liquid level in the tank is maintained between the intermediate set level of the intermediate level gauge 54b and the high set level of the upper limit level gauge 54a, and is adjusted as necessary to compensate for the amount lost due to spraying. Dilution water is supplied from a dilution water supply system 563. The supply amount is at a ratio of disinfectant solution: water for dilution = 1:9.

By this spraying, foreign substances such as floating bacteria and dust contained in the air 51 to be sterilized collide with the spray water of the sprayed sterilizing agent solution, and are captured and sterilized. Further, the spray water of the disinfectant solution that has reached the media 506 causes floating bacteria and dust attached to the media 506 to flow down, and also takes in foreign substances such as floating bacteria and dust contained in the air 51 to be sterilized, and the water is transferred to the circulation tank 50. flow inside.

In the circulation tank 54, slightly acidic electrolyzed water is dripped at a small flow rate for replenishment, and the effective chlorine concentration of the disinfectant solution in the circulation tank 54 is maintained at a dilution concentration of 0.1-10 mg/L suitable for sterilization. Therefore, bacteria flowing into the circulation tank 54 can be reliably sterilized. Furthermore, by directly spraying the disinfectant solution onto the air 51 to be sterilized with high saturation efficiency, foreign matter such as floating bacteria and dust contained in the air 51 to be sterilized can be incorporated into the disinfectant solution. In addition to sterilization, dust removal can also be achieved.

The sterilized air that has passed through the media 506 passes through the eliminator 507 and is supplied into the room by the fan device 600.

When the airflow of the air 8 to be sterilized flows at a low wind speed, when the airflow passes through the small opening of the capture member 40 of the eliminator 31 for low wind speed, the mist in the airflow is captured by the eliminator 31 for low wind speed. It is captured by inertial collision with the member 40 in the airflow. The low-speed airflow with weak carrying power will not entrain the mist again. The captured mist travels along the capture member 40 to the front of the eliminator 507 and falls into the machine.

When the airflow of the air 8 to be sterilized flows at a high wind speed, an inertial force acts on the mist moving with the airflow, and when the high wind speed airflow passes through the curved flow path 49 of the high wind speed eliminator 32, The mist that moves along with the high speed air current does not follow the change in the path of the air current, but moves in the inertial direction, deviates from the air current, and hits the wall surface of the eliminator flow path, that is, the wall surface of the bent portion 45a of the element 45. The particles collide and are captured, travel along the wall surface of the bent portion 45a, gather, and fall into the low wind speed eliminator 31 through the opening 45d.

In this embodiment, the element 45 of the high wind speed eliminator 32 has the side wall 45b that closes both ends of the bent portion 45a facing the inner surface of the frame 46, so that the side wall 45b suppresses deformation of the bent portion 45a. Functions as a structural material. That is, by connecting both wings in the cross-sectional shape of the bent portion 45a with the side wall 45b, it is possible to prevent the wings from approaching and separating and deforming the element 45, and to set the gap width of the flow path 49 between the adjacent elements 45. The mist removal performance of the high wind speed eliminator 32 can be extended for a long time by reliably maintaining the value, here, at the optimum value determined by analysis, experiment, etc. In this way, by maintaining the gap width of the flow path 49 between the elements 45 of the high wind speed eliminator 32 at an optimum value, even ultrafine particle-like mist having a small mass can be captured. Furthermore, since the plurality of grooves 45e of the bent portion 45a suppress the bending of the bent portion 45a, it is strengthened that the gap width of the flow path 49 between the elements 45 of the high wind speed eliminator 32 is maintained at an optimum value. .

Further, the side wall 45b prevents the mist captured by the high wind speed eliminator 32 from flowing out from the element 45 through the inner surface of the frame body 46 to the interior wall surface of the machine, and can prevent rusting inside the machine and the fan device 600 and the like.

The elements 45 are connected to each other by the fitting part 62 without the use of adhesive, and the elements are structured so that they can be separated and recombined. Therefore, scale (scale) and slime (mucus-like substances) that adhere to the elements are prevented. Maintenance to remove mist can be easily performed, and the eliminator's mist removal function can be used for a long time. Further, since the contact portion 61 defines the gap width of the flow path 49 between adjacent elements 45, the gap width of the flow path 49 can be reliably reproduced even if maintenance is performed to separate the elements 45.

Since the plurality of elements 45 are housed in the frame 46, the high wind speed eliminator 32 can be easily taken in and out of the eliminator case 30. When a plurality of elements 45 are housed in the frame 46, the elements 45 can be easily inserted into the frame 46 by joining the side walls 45b of the elements 45 in a row with tape.
