[Ion exchange equipment]
FIG. 1 is a cross-sectional view illustrating the ion exchange device of the present embodiment.
The ion exchange apparatus 1 shown in FIG. 1 is a substantially cylindrical column as a whole. And an ion exchange means filling unit 10 for filling ion exchange means for subjecting the liquid to be treated to ion treatment, and a collector part 20 as an example of a solid-liquid separation means for separating the ion exchange means and the treatment liquid, A main part is constituted by a liquid collecting part 30 for collecting the processing liquid separated by the collector part 20. The ion exchange means filling unit 10, the collector unit 20, and the liquid collection unit 30 are arranged from the upper direction to the lower direction, respectively. And in the location of the flange part 11 of the ion exchange means filling part 10 and the flange part 33 of the liquid collection part 30, the collector part 20 is connected with the bolt and the nut on both sides of the details plate plate 22 mentioned later in detail.

  The ion exchange means filling unit 10 is filled with ion exchange means, and performs ion exchange treatment of the liquid to be treated. In the present embodiment, the ion exchange means is an ion exchange resin. There is no restriction | limiting in particular in the ion exchange resin used by this Embodiment, Chelate resin, a synthetic adsorbent, etc. can be filled in addition to a general cation exchange resin and an anion exchange resin. As the shape, various shapes such as a granular shape and a cylindrical shape can be filled, and there is no particular limitation. Moreover, as a magnitude | size, it is 0.1 mm-1 mm, for example. The ion exchange resin is filled in the ion exchange means filling unit 10 so as to have, for example, a bulk volume that occupies about 50%.

  Although the to-be-processed liquid which performs an ion exchange process with the ion exchange apparatus 1 of this Embodiment is not restrict | limited in particular, For example, it is industrial water and tap water as raw | natural water used in order to manufacture a pure water. Yes, or a sugar solution used for decolorization or desalting, or salt water used for purification. In any case, it does not prevent the direct introduction into the ion exchange apparatus 1 as the liquid to be treated. However, it is usually preferable to remove solids with a filter or the like. Moreover, it is preferable to perform in advance an activated carbon treatment with an activated carbon treatment apparatus or the like to remove organic substances such as a solvent or heavy metal ions contained in the liquid to be treated.

  Such a liquid to be treated is introduced into the ion exchange means filling unit 10 from the pipe 12 provided at the upper part of the ion exchange means filling unit 10. And a to-be-processed liquid distribute | circulates toward the lower part of the ion exchange means filling part 10, contacting the ion exchange resin with which the ion exchange means filling part 10 was filled. At this time, the liquid to be treated is subjected to ion exchange treatment with an ion exchange resin. In other words, when the ion exchange resin is a cation exchange resin, a cation such as a metal ion contained in the liquid to be treated is exchanged with an ion provided in the cation exchange resin, such as sodium ion or hydrogen ion. As a result, cations in the liquid to be treated are removed. When the ion exchange resin is an anion exchange resin, the anion contained in the liquid to be treated is exchanged with ions provided in the anion exchange resin, for example, hydroxide ions. Anions in the liquid are removed.

  A distributor (not shown) may be connected to the pipe 12 in order to further disperse the liquid to be treated and bring it into contact with the ion exchange resin. The distributor is, for example, a tubular body provided with a large number of small holes. A distributor is provided above the ion exchange resin, and the liquid to be processed can be sprayed more uniformly to the ion exchange resin by spraying the liquid to be processed from the small holes.

  The interior of the ion exchange means filling unit 10 is provided with a lining (not shown). By applying the lining, the material having the strength of carbon steel or the like constituting the ion exchange apparatus 1 but having inferior corrosion resistance may be brought into non-contact with the chemical having corrosive properties used for the regeneration of the liquid to be treated or the ion exchange resin. it can. Thereby, the maintenance frequency of the ion exchange device 1 can be reduced, and the life of the ion exchange device 1 can be extended. The material of the lining can be appropriately selected depending on the type of cation or anion contained in the liquid to be processed, the type of liquid to be processed, the chemical used, and the like. In the present embodiment, for example, a rubber lining made of hard rubber or the like is used.

The collector unit 20 is installed to take out the processing liquid from the ion exchange means filling unit 10.
FIG. 2 is an enlarged view of a part of the collector unit 20.
Hereinafter, the collector unit 20 will be described with reference to FIGS. 1 and 2.
In the present embodiment, the collector unit 20 is provided with a strainer 21 as an example of a separation unit having a gap for separating the ion exchange resin and the processing liquid, and an opening 25 for arranging the strainer 21. An eye plate 22 as an example of a plate part, a lining 23 as an example of a cover part for covering the surface of the eye plate 22 and making the eye plate 22 and the processing liquid non-contact, and an eye plate And an adapter 24 as an example of a fixing portion that is arranged in the opening 25 of the 22 and is joined to the lining 23 and fixes the strainer 21. In FIG. 2, the strainer 21 is illustrated in a separated state for convenience of explanation.

  The strainer 21 includes a head 211 having a function of separating the ion exchange resin and the processing liquid, and an attachment portion 212 for attaching the strainer 21.

The head 211 is provided with a plurality of slits 213 as an example of a gap for separating the ion exchange resin and the processing liquid. The slit 213 is made narrower than the width through which the solid ion exchange resin can pass. In this case, the ion exchange resin cannot pass through the slit 213, but the treatment liquid that is a liquid can pass through the slit 213, so that the ion exchange resin and the treatment liquid can be separated. That is, solid-liquid separation can be performed.
The strainer 21 has a hollow portion inside, and the hollow portion has a discharge port 215 at the lower portion of the attachment portion 212. That is, the processing liquid that has passed through the slit 213 enters the hollow portion inside the strainer 21 and is then discharged from the discharge port 215. At this time, the discharge port 215 is open to the liquid collection unit 30 side. Therefore, by using the strainer 21 having the structure as described above, first, the treatment liquid is separated from the ion exchange resin on the ion exchange means filling unit 10 side, and then the treatment liquid is discharged to the liquid collection unit 30 side. Work can be performed continuously.

A threaded portion 216 is formed on the surface of the attachment portion 212. Although described in detail later, the strainer 21 is fixed by using the threaded portion 216.
The strainer 21 is made of, for example, a material such as a resin having thermoplasticity, and can be manufactured by injection molding or the like. Further, a large number of strainers 21 are attached from the viewpoint that the ion exchange resin and the processing liquid can be separated uniformly and at a higher speed. In the present embodiment, for example, this number can be 160.

The eye plate 22 is a partition that separates the ion exchange means filling unit 10 and the liquid collection unit 30. For this purpose, the eye plate 22 is prepared according to the shape of the horizontal section of the ion exchange device 1. When the horizontal cross section of the ion exchange device 1 is circular, the countersink plate 22 has a disk shape. Further, the countersink plate 22 is required to have a strength that can withstand the pressure of the ion exchange resin filled in the ion exchange means filling unit 10 and the liquid to be treated. Therefore, in this embodiment, a metal plate made of a material such as carbon steel having a predetermined thickness is used.
Further, the eye plate 22 also plays a role of fixing the strainer 21. Therefore, the eye plate 22 has a plurality of openings 25 for arranging the strainer 21. Since the opening 25 is formed through the eye plate 22, when the strainer 21 is disposed at the position of the opening 25, the treatment liquid is passed from the ion exchange means filling unit 10 to the liquid collection unit through the strainer 21. 30 can be moved and discharged.

  The lining 23 is provided to cover the surface of the eye plate 22 so that the eye plate 22 is not in contact with the treatment liquid and the medicine to be used. The lining 23 covers the entire surface of the eye plate 22. That is, not only the surface of the eye plate 22 on the side of the ion exchange means filling unit 10 and the surface of the liquid collection unit 30 but also the inner periphery of the opening 25 of the eye plate 22 is covered. Thereby, in this Embodiment, the location where the eye plate 22 and a process liquid and the chemical | medical agent to be used do not exist. The material for forming the lining 23 is required not to be corroded by the liquid to be treated or the chemical used, and to have good workability so as to cover the eye plate 22 without a gap. From this viewpoint, the lining 23 is preferably a rubber lining made of a rubber composition. More specifically, for example, a hard rubber material cured by vulcanizing natural rubber can be used.

  The adapter 24 fixes the strainer 21 to the countersink plate 22 or the like by inserting the mounting portion 212 of the strainer 21 inside the adapter 24. That is, it is provided between the lining 23 and the strainer 21 and fixes the strainer 21 to the countersink plate 22 or the like. Therefore, as described above, the threaded portion 216 is formed on the surface of the attachment portion 212 of the strainer 21, and the threaded portion 241 is also formed inside the adapter 24 together with the threaded portion 216. Then, by engaging the threaded portion 216 and the threaded portion 241 with each other, the strainer 21 and the adapter 24 can be screwed together, and the strainer 21 can be fixed to the countersink plate 22 or the like. That is, the strainer 21 is fixed to the adapter 24 via the threaded portions 216 and 241. In the case of this embodiment, since the strainer 21 and the adapter 24 are fastened with screws, the strainer 21 is fixed to the adapter 24 in a detachable state. Therefore, even when the strainer 21 is replaced, the strainer 21 can be easily attached and detached. In the present embodiment, the head 211 of the strainer 21 is fixed in close contact with the adapter 24 and the lining 23 without any gap. When the gap is generated, the ion exchange resin may enter the gap and further leak out to the liquid collection unit 30 side. By closely adhering as in the present embodiment, the ion exchange resin and the treatment liquid can be more reliably separated.

  Further, in the present embodiment, the strainer 21 and the adapter 24 are fastened with screws, so that the strainer 21 can be fixed. Therefore, it is necessary to adopt a method of attaching a nut to the attachment portion 212 and fixing it to the countersink plate 22 or the like. There is no. In order to attach and fix the nut to the attachment portion 212, it is necessary for the operator to enter the liquid collecting portion 30 and perform the operation of attaching the nut. For this purpose, it is necessary to make the space of the liquid collection part 30 large enough for an operator to enter. Furthermore, a large-diameter outlet portion is required for an operator to access the liquid collection portion 30. On the other hand, in the present embodiment, it is not necessary to make the space for the liquid collection unit 30 large enough for an operator to enter. And the large diameter exit part for an operator to access in the liquid collection part 30 is unnecessary, and a small diameter may be sufficient. Therefore, the space of the liquid collection part 30 can be reduced. Therefore, it can be suppressed that the treatment liquid is diluted and the purity of the treatment liquid is lowered due to the space of the liquid collection unit 30 being too large. Moreover, it becomes difficult to dilute the chemicals used during the regeneration of the ion exchange resin and the retention of the washing water used during the cleaning of the ion exchange resin, and it is possible to suppress a decrease in the regeneration efficiency and detergency of the ion exchange resin.

  Further, the lining 23 and the adapter 24 are joined in a state where they cannot be attached and detached. Thereby, the adapter 24 can be firmly fixed to the location of the opening 25 of the eye plate 22. In order to realize this, the adapter 24 is preferably made of a material that is firmly bonded to the lining 23, for example, the same rubber composition. Thereby, the lining 23 and the adapter 24 can be joined by a vulcanization process. And since the lining 23 and the adapter 24 which were joined by the vulcanization process are almost integrated, a strong joining can be realized. Note that the adapter 24 is preferably formed of ebonite having higher machining accuracy among rubber compositions. That is, in order to create the threaded portion 241 formed inside the adapter 24, it is necessary to thread the inside of the adapter 24. When the adapter 24 is made of ebonite, threading can be performed with higher accuracy.

In the present embodiment, the strainer 21 can be attached more accurately by arranging the strainer 21 via the lining 23 and the adapter 24 at the position of the opening 25 of the countersink plate 22.
FIGS. 3A and 3B are diagrams illustrating a configuration in which the strainer 21 is attached to the eye plate 22.
Here, FIG. 3A is a view for explaining a case where the threader 21 is directly attached to the lining 23 provided in the opening 25 and the strainer 21 is attached to the eye plate 22 without using the adapter 24. FIG. 3B illustrates the case where the adapter 24 is used, but the adapter 24 is attached without providing the lining 23 on the inner periphery of the opening 25, and the strainer 21 is attached to the eye plate 22. is there.
In the case of FIG. 3A, the threaded portion 221 is formed directly in the opening 25 of the countersink plate 22, and the strainer 21 is attached using this. However, it is difficult to accurately form a large number of openings 25 in the vertical direction with respect to the countersink plate 22. When the opening 25 cannot be formed accurately in the vertical direction, the strainer 21 is attached in an oblique direction which is a direction shifted from the vertical direction as shown in FIG. In this case, since the head 211 of the strainer 21 cannot be attached in close contact, a gap 26 is formed. In this case, leakage of the ion exchange resin as described above tends to occur from the gap 26. In the case of the present embodiment, there are 160 strainers 21 as described above, and it is desirable that none of the strainers 21 be formed obliquely.

Further, the same can be said for the case of FIG. In this case, as for the adapter 24, if the threaded portion 241 is precisely selected and used, the problem described with reference to FIG. 3A does not occur. However, as in the case of FIG. 3A, it is difficult to accurately form all the openings 25 in which the eye plate 22 is formed in the vertical direction. Therefore, when the opening 25 cannot be formed accurately in the vertical direction, the strainer 21 is attached in an oblique direction that is a direction shifted from the vertical direction. Also in this case, the ion exchange resin leaks easily from the gap 26.
That is, in the case of FIGS. 3A to 3B, the mounting accuracy of the strainer 21 is defined by the processing accuracy of the opening 25 formed in the countersink plate 22. However, since it is difficult to accurately form all of the plurality of openings 25 in the vertical direction, it is difficult to avoid all the strainers 21 being attached in an oblique direction. Further, the bondability between ebonite, which is the material of the adapter 24, and carbon steel, which is the material of the eye plate 22, is poor, and the adapter 24 may be detached from the eye plate 22.

  On the other hand, in the present embodiment, the strainer 21 is attached via the lining 23 and the adapter 24. In order to actually arrange the adapter 24, for example, the adapter 24 is disposed on the lining 23 made of a rubber composition or the like, and the lining 23 and the adapter 24 are joined by vulcanization. At this time, at the stage before vulcanization in which the adapter 24 is disposed, the lining 23 is in a state of plasticity, so that the orientation in which the adapter 24 is disposed can be adjusted. Therefore, even if the opening 25 is not formed in the vertical direction with respect to the countersink plate 22, it is easy to arrange the adapter 24 in the vertical direction. As a result, the strainer 21 attached to the adapter 24 is also arranged in the vertical direction with respect to the eye plate 22.

The liquid collection unit 30 is provided to collect the processing liquid separated by the collector unit 20. In the present embodiment, the liquid collection unit 30 includes a cylindrical straight barrel portion 31 and an end plate portion 32 that is positioned below the straight barrel portion 31 and curves in an arc. In FIG. 1, the boundary between the straight body portion 31 and the end plate portion 32 is indicated by a dotted line.
The processing liquid discharged from the discharge port 215 of each strainer 21 of the collector unit 20 flows through the lower part as it is, and moves downward along the inner wall of the end plate part 32. And it collects in the exit part 35 provided in the lower part of the liquid collection part 30. FIG. Then, the processing liquid can be discharged from the ion exchange device 1 through the outlet portion 35.
The inside of the liquid collection unit 30 is also provided with a lining such as a rubber lining (not shown), so that the treatment liquid and the agent to be used are not in contact with the material such as carbon steel forming the liquid collection unit 30.

In addition, the ion exchange apparatus 1 of this Embodiment can also be grasped | ascertained as a solid-liquid separation apparatus.
That is, the ion exchange apparatus 1 of the present embodiment includes a strainer 21 having a slit 213 for separating a solid and a liquid, an eye plate 22 provided with an opening 25 for arranging the strainer 21, A lining 23 that covers the inner periphery of the opening 25 of the plate 22, and an adapter 24 that is disposed in the opening 25 of the eye plate 22 and that joins the lining 23 and fixes the strainer 21. 21 and the adapter 24 are formed with threaded portions 216 and 241 respectively, and the strainer 21 is also considered to be a solid-liquid separator characterized by being fixed to the adapter 24 via the threaded portions 216 and 241.

Further, the portion of the collector unit 20 excluding the strainer 21 can be regarded as a support structure for the strainer 21.
That is, the portion excluding the strainer 21 of the collector unit 20 is a support structure of the strainer 21 used for separating the solid and the liquid, and the eye plate plate provided with the opening 25 for arranging the strainer 21. 22, a lining 23 that covers the inner periphery of the opening 25 of the eye plate 22, and an adapter 24 that is provided between the lining 23 and the strainer 21 and fixes the strainer 21. 24 is considered to be a support structure of the separating portion, which is joined in a non-detachable state, and the strainer 21 is fixed to the adapter 24 in a removable state.

[Production method of collector part]
Next, the manufacturing method of the collector part 20 demonstrated in FIG. 1 and FIG. 2 is demonstrated.
4A to 4F are diagrams illustrating an example of a method for manufacturing the collector unit 20.
First, as shown in FIG. 4A, an opening 25 is formed in the eye plate 22. The opening 25 can be formed by ordinary machining. As described above, the opening 25 is not necessarily formed in the vertical direction with respect to the countersink plate 22.

  Next, as shown in FIG. 4B, a lining 23 is performed on the surface of the countersink plate 22 using a rubber composition. At this time, since the lining 23 is plastic before vulcanization, it has a high degree of freedom for the shape. Therefore, the lining 23 can be formed so as to cover the surface of the countersink plate 22 with a uniform thickness.

  Then, as shown in FIG. 4C, the adapter 24 that has been prepared in advance is inserted into the opening 25 in which the lining 23 is formed. In this embodiment, the adapter 24 can be manufactured by forming a through hole in a cylindrical ebonite and further forming a threaded portion 241 inside the through hole. Further, when the adapter 24 is inserted, since the lining 23 is plastic at this point, it can be positioned freely. Therefore, positioning can be performed in such a direction that the adapter 24 is attached to the eye plate 22 in the vertical direction. Actually, the adapter 24 is inserted so as to be in close contact with the lining 23 using a spatula or the like.

  Further, as shown in FIG. 4 (d), vulcanization is performed, and the lining 23 is solidified. At this time, the lining 23 is joined to the eye plate 22 and to the adapter 24.

  Next, as shown in FIG. 4 (e), the rubber composition around the adapter 24 raised when the adapter 24 is inserted is scraped off. Furthermore, surface processing such as grinding and polishing is performed in order to minimize surface irregularities. Thereby, the lining 23 and the adapter 24 can be made into the continuous plane shape.

  Finally, as shown in FIG. 4F, the strainer 21 is attached to the adapter 24 by screwing. As described above, the adapter 24 is arranged in the vertical direction with respect to the countersink plate 22. Therefore, the strainer 21 can also be attached to the eye plate 22 in the vertical direction. Furthermore, since the lining 23 and the adapter 24 have a continuous flat shape, the head 211 of the strainer 21 can be attached in close contact with the flat surface. The collector part 20 can be manufactured by the series of steps described above.

  EXAMPLES Hereinafter, although this invention is demonstrated in detail using an Example, this invention is not limited by these Examples, unless the summary is exceeded.

Example 1
The collector part 20 described in FIGS. 1 and 2 was manufactured by the method described in FIG. And the ion exchange apparatus 1 using this collector part 20 was manufactured.
Here, the strainer 21 is made of resin, and one that is produced by injection molding is used. The eye plate 22 was made of carbon steel, and the eye plate 22 was covered with a lining 23 made of hard rubber. Further, the adapter 24 is made of ebonite.

The ion exchange device 1 produced in the present embodiment has a diameter of 1500 mm and an overall height of 4000 mm. At this time, the height of the straight body part 31 of the liquid collection part 30 was 200 mm. In this case, when the strainer 21 is fixed with a nut, the height of the straight body 31 as a work space needs to be 700 mm, and thus the height of the straight body 31 can be reduced by 500 mm. The volume of the straight body portion 31 could be 1.6 m ³ to 0.7 m ³ .

Furthermore, the compression test of the collector part 20 was done using the compression tester.
FIG. 5 is a diagram illustrating a compression test of the collector unit 20.
As shown in FIG. 5, the compression test was performed using a sample manufactured for a part of the collector portion 20. In this sample, only one strainer 21 is attached. The compression test was performed by applying a load to the head 211 of the strainer 21. Thereby, the relative intensity | strength of each part which comprises the collector part 20 can be measured.
As a result of this compression test, the head portion 211 of the strainer 21 was crushed and destroyed first. That is, it can be said that the strength of joining of the adapter portion 24 and the lining portion 23 is stronger than the strength of the strainer 21. The strainer 21 is designed to have sufficient strength to support the pressure of the ion exchange resin and the liquid to be processed inside the ion exchange means filling unit 10.
