I try to dehumidify.

That is, the moist air supplied from the fluid supply port into the sealed container comes into contact with the moisture adsorbent, and at this time, the water contained in the moist air is adsorbed by the moisture adsorbent and separated from the moist air. As a result, the moist air is dehumidified into dry air, and the dry air is sent to the outside of the sealed container through the fluid discharge port.

A dehumidifying device has been proposed in which the dehumidifier configured as described above is used as a dehumidifying unit to connect a plurality of dehumidifying units to dehumidify a large amount of moist air. As shown in FIG. 5, the fluid discharge member 72 of the dehumidifier 71 is supported by the support legs 73 fixed to both ends of the lower surface thereof. Posts 74 extending upward are fixed to both ends of the upper surface of the fluid discharge member 72. A plurality of dehumidifying units 75 are arranged between both columns 74, and the lower parts of the dehumidifying units 75 are fixed by a plurality of lower bolts 76 screwed from the lower surface of the fluid discharge member 72. A gap having a width of L is formed by the support leg 73 between the installation surface of the dehumidifier 1 and the lower surface of the fluid discharge member 72, and the operator can loosen the lower bolt 76 with a spanner or the like. I am able to

The support columns 74 support the fluid supply member 77, and the lower surface of the fluid supply member 77 contacts the upper ends of the plurality of dehumidifying units 75. An upper bolt 78 is screwed into the upper surface of the fluid supply member 77, and the upper portion of the dehumidifying unit 75 is fixed to the fluid supply member 77 by the bolt 78. That is, each dehumidifying unit 75 is fixed from the upper and lower ends by the lower bolt 76 and the upper bolt 78.

A fluid inlet 79 for introducing wet air into the dehumidifying device 71 is provided on one side of the fluid supply member 77. The fluid inlet 79 communicates with the fluid supply port of each dehumidifying unit 75. There is. In addition, a fluid outlet port 80 is provided on one side of the fluid discharge member 72 for leading out the dehumidified dry air from the dehumidifier 71, and the fluid outlet port 80 is a fluid discharge port of each dehumidifying unit 75.

[0008]

[Problems to be solved by the device]

 However, when removing the dehumidifying unit 75 for replacement or the like, the worker must first loosen the lower bolt 76 with a wrench or the like, and then loosen the upper bolt 78 with a wrench or the like to release the dehumidifying unit 75. . Therefore, in order to remove the dehumidifying unit 75, a very troublesome work must be performed, and there is a problem that the maintainability is poor.

Further, in order to be able to loosen the lower bolt 76, the distance L between the installation surface of the dehumidifier 71 and the lower surface of the fluid discharge member 72 should be set large so that the operator can put his or her hand in. It must be possible to loosen the lower bolt 76 with a wrench or the like. Therefore, there is a problem that a space is wasted below the fluid discharge member 72, and the space saving property of the dehumidifier 1 is deteriorated.

The present invention has been made to solve the above problems, and an object of the present invention is to remove the dehumidifying unit easily, to eliminate wasted space, and to improve space saving. It is to provide a dehumidifying device capable of performing.

 Therefore, in the invention of claim 1, the fluid to be dehumidified is introduced into the introduction port of the dehumidifier through the introduction passage of the fluid supply / discharge member. The fluid to be dehumidified introduced into the introduction port flows through the dehumidification part material from the introduction port side toward the derivation port side. At this time, the water contained in the dehumidified fluid permeates the dehumidifying member itself to be separated from the dehumidified fluid, and the dehumidified fluid is dehumidified. The dehumidified fluid to be dehumidified is sent out to the inlet, and further sent out to the outlet passage of the fluid supply / discharge member communicating with the outlet. The dehumidifier is removably suspended and fixed to the fluid supply / discharge member.

In the invention of claim 2, the fluid to be dehumidified is introduced into the introduction port of the dehumidifier via the introduction passage of the fluid supply / discharge member. The fluid to be dehumidified introduced into the inlet port is circulated from the inlet port side toward the outlet port side in the hollow fiber bundle made of the polymer permeation membrane. At this time, the water contained in the dehumidified fluid permeates the hollow fiber bundle itself to be separated from the dehumidified fluid, and the dehumidified fluid is dehumidified. The dehumidified fluid to be dehumidified is sent out to the inlet, and further sent out to the outlet passage of the fluid supply / discharge member that communicates with the outlet. Further, the dehumidifier is detachably fixed to the fluid supply / discharge member in a suspended manner.

【Example】

 An embodiment embodying the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, struts 2 as support members extending upward are fixed to the left and right ends of the upper surface of the base 1a of the dehumidifier 1 by lower bolts 3. A fluid supply / discharge member 4 is supported by the pair of right and left columns 2, and the fluid supply / discharge member 4 is fixed to the upper end of the column 2 by an upper bolt 5. A dehumidifying unit 6 that constitutes a plurality of dehumidifiers is hung on the lower surface of the fluid supply / drainage member 4, and a distance L is provided between the lower end surface of each dehumidifying unit 6 and the upper surface of the base 1a. A gap having a width is formed. In FIG. 1, the left side of the paper is the left side of the dehumidifier 1, and the right side of the paper is the right side of the dehumidifier 1.

The fluid supply / discharge member 4 is composed of connection blocks 7 a to 7 e, an introduction block 8, and a discharge block 9. The connecting blocks 7a to 7e are formed in a substantially rectangular parallelepiped, and two dehumidifying units 6 are respectively hung on the lower surfaces of the blocks 7a to 7e, as shown in FIG. Note that only the connecting block 7a is shown in FIG.

The connecting blocks 7a to 7e are arranged side by side so that the right and left side surfaces thereof come into contact with each other. Further, an introduction block 8 and a derivation block 9 are provided in parallel with the connection blocks 7a and 7e, respectively, outside the connection blocks 7a and 7e at both ends. The connecting blocks 7a to 7e, the introducing block 8 and the deriving block 9 are connected to each other by a removable connecting tool 10, and by removing the connecting tool 10, the connection can be released.

A fluid intake passage 11 for taking in humid air is formed in the introduction block 8, and the fluid intake passage 11 is branched into four inside the introduction block 8. Then, each fluid intake passage 11 is connected to four fluid introduction passages 12 formed in each of the connection blocks 7a to 7e. In each of the fluid introduction passages 12, one fluid supply port 13 is formed for each of the connection blocks 7a to 7e. Therefore, when wet air is introduced into the fluid intake passage 11, the wet air flows through the fluid introduction passage 12 and is sent out to the dehumidifying unit 6 from the fluid supply ports 13 of the connection blocks 7a to 7e.

A fluid take-out passage 14 for taking out dry air is formed in the lead-out block 9, and the fluid take-out passage 14 is branched into two inside the lead-out block 9. Then, each fluid extraction passage 14 communicates with a fluid discharge passage 15 formed in each of the connection blocks 7a to 7e. In each of the fluid outlet passages 15, one fluid outlet 16 is formed for each of the connecting blocks 7a to 7e. Therefore, the dry air sent out from the dehumidifying unit 6 is sent out to the gas outlet passage 15 via each fluid outlet 16, and further flows through the fluid outlet passage 14 to be led out to the outside of the fluid supply / discharge member 4. It has become.

Next, the dehumidifying unit 6 will be described. Since the connecting blocks 7a to 7e and the dehumidifying units 6 hung on the connecting blocks 7a to 7e have the same configuration, they are hung on the connecting block 7a. Only the dehumidifying unit 6 that has been performed will be described.

As shown in FIG. 3, two recesses 20 are formed on the lower surface of the connecting block 7 a, and the inside of each recess 20 is communicated with the fluid introduction passage 12 through the fluid supply port 13. . The fluid discharge port 16 is formed so as to extend downward from the upper surface of the recess 20.

A cylindrical body 21 constituting the dehumidifying unit 6 is fitted in each recess 20, and a first seal member 22 is provided on the fitting surface on the recess 20 side. A packing 23 is interposed between the upper end surface of the cylindrical body 21 and the upper surface of the recess 20. Further, the fixing bolt 24 screwed from the upper surface of the connecting block 7a is screwed into the upper end surface of the tubular body 21, and the tubular body 21 is attached to the connecting block 7a by the fixing bolt 24.

Therefore, since the dehumidifying unit 6 including the tubular body 21 is attached to the connecting block 7a only with the fixing bolts 24, the dehumidifying unit 6 can be easily removed from the connecting block 7a by loosening the fixing bolts 24. Becomes

A dehumidifying member 25, which is formed by bundling a plurality of hollow fibers made of a polymer permeable membrane into a cylindrical shape, is housed inside the cylindrical body 21, and a communication pipe 26 is provided at the center of the dehumidifying member 25. Has been inserted. One end of the communication pipe 26 is fitted into the fluid discharge port 16, and a second seal member 27 is provided on the fitting surface on the fluid discharge port 16 side. Outer seal members 28 are provided between the upper and lower outer peripheral surfaces of the dehumidifying member 25 and the inner surface of the tubular body 21, respectively, and the upper and lower inner peripheral surfaces of the dehumidifying member 25 and the outer periphery of the communication pipe 26 are disposed. Inner sealing members 29 are respectively arranged between the surfaces. Therefore, by disposing the dehumidifying member 25 in the cylindrical body 21, the fluid introducing chamber 30 is formed inside the recess 20.

Further, due to the gap between the inner peripheral surface of the dehumidifying member 25 and the communication pipe 26, the gap between the outer peripheral surface of the dehumidifying member 25 and the cylindrical body 21, and the gap between the hollow fibers forming the dehumidifying member 25 and the hollow fibers. A purge air passage 25a is formed. The cylindrical body 21 is formed with a purge air outlet portion 21a for communicating the purge air passage 25a with the outside of the dehumidifying unit 6.

Next, an opening of a cap 31 formed in a bottomed cylindrical shape is fitted into the lower end of the cylinder 21, and a third seal member 31a is arranged on the fitting surface on the cylinder 21 side. ing. A fluid outlet chamber 32 is formed inside the cap 31. The cap 31 supports the communication pipe 26, and a communication hole 33 is formed at the lower end of the communication pipe 26 to connect the fluid outlet chamber 32 and the inside of the communication pipe 26. Further, the communication pipe 26 is formed with a purge air inlet portion 26a that connects the communication pipe 26 and the purge air passage 25a.

Therefore, the moist air is supplied from the fluid introduction passage 12 through the fluid supply port 13 to the fluid introduction chamber 30 of the dehumidifying unit 6, and further circulates inside the hollow fibers constituting the dehumidification member 25. It is supposed to do. Then, the moist air is dehumidified inside the hollow fiber to become dry air. The dry air is sent out to the fluid outlet chamber 32, and further sent out to the fluid outlet passage 15 via the communication pipe 26 and the fluid outlet 16.

Further, a part of the dry air passing through the communication pipe 26 is supplied to the purge air passage 25a via the purge air inlet portion 26a. Then, when this dry air passes through the purge air passage 25a, that is, the outside of each hollow fiber constituting the dehumidifying member 25, the action of the permeation membrane dehumidifies the moist air flowing inside each hollow fiber. .

Next, the operation of the dehumidifying device 1 configured as described above will be described. First, when moist air is supplied to the fluid intake passage 11 of the fluid supply / discharge member 4, the moist air flows through the fluid introduction passage 12 and is dehumidified through the fluid supply ports 13 of the connection blocks 7a to 7e. It is introduced into the fluid introduction chamber 30 of the unit 6. The moist air introduced into the fluid introduction chamber 30 circulates inside the hollow fibers constituting the dehumidifying member 25 from the fluid introduction chamber 30 side toward the fluid derivation chamber 32 side.

At this time, the moisture contained in the moist air penetrates into the hollow fiber itself to be separated from the moist air, and as a result, the moist air is dehumidified into dry air. The dry air is sent out to the fluid outlet chamber 32 after passing through the hollow fiber, and the dry air flows through the communication pipe 26. Further, the dry air is sent out to the fluid outlet passage 15 of the fluid supply / discharge member 4 via the fluid outlet 16. The dry air sent to the fluid outlet passage 15 is led to the outside of the fluid supply / discharge member 4 via the fluid outlet passage 14.

Further, a part of the dry air flowing through the communication pipe 26 is sent out to the purge air passage 25a via the purge air inlet portion 26a. The dry air flowing through the purge air passage 25a becomes wet air by taking in the water that has permeated the hollow fibers into the gas, and the wet air is discharged from the purge air outlet 21a.

Next, when removing the dehumidifying unit 6 from the dehumidifying device 1 for replacement or the like, first, the fixing bolt 24 that fixes the dehumidifying unit 6 to the dehumidifying device 1 is loosened. Then, the dehumidifying unit 6 is released from the fixed state and is in a removable state. When the dehumidifying unit 6 is pulled downward in this state, the upper end of the tubular body 21 is disengaged from the recess 20, and the upper end of the communication pipe 26 is disengaged from the fluid discharge port 16, and as shown in FIG. 6 is removed from the dehumidifier 1. Further, since a gap having a width of the distance L is formed between the lower end of the dehumidifying unit 6 and the upper surface of the base 1a, the dehumidifying unit 6 can be easily pulled downward.

Next, in order to fix the dehumidifying unit 6 to the dehumidifying device 1 again, the upper end of the tubular body 21 is fitted into the recess 20, and the upper end of the communication pipe 26 is fitted into the fluid discharge port 16. This fitting is easily performed by the gap provided between the dehumidifying unit 6 and the base 1a. In this state, the upper end surface of the tubular body 21 is brought into contact with the upper surface of the recess 20, and the fixing bolt 24 is screwed into the upper surface of the fluid supply / discharge member 4. Then, the dehumidifying unit 6 is fixed to the dehumidifying device 1 by screwing in the fixed bolt 24.

As described above in detail, in this embodiment, the dehumidifying unit 6 is suspended and fixed to the fluid supply / discharge member 4 only by the fixing bolt 24. Therefore, when removing the dehumidifying unit 6, it is only necessary to loosen the fixing bolts 24, so that the dehumidifying unit 6 can be easily removed and the maintainability of the dehumidifying unit 6 can be improved.

Since the gap formed between the dehumidifying unit 6 and the base 1a is for removing or attaching the dehumidifying unit 6 unlike the conventional case, the width of the gap, that is, the distance L is determined by the operator's hand. It doesn't have to be so large that Therefore, the distance L can be reduced and the space saving property of the dehumidifying device 1 is improved.

In the present embodiment, the connecting blocks 7 a to 7 e of the fluid supply / discharge member 4 to which the dehumidifying unit 6 is suspended and fixed are connected by the connecting tool 10. Therefore, the number of dehumidifying units 6 installed can be freely set according to the flow rate of wet air. That is, when increasing the number of dehumidifying units 6 installed, the number of connecting blocks may be increased, and when decreasing the number of dehumidifying units installed, the number of connecting blocks may be decreased.

The present invention is not limited to the above embodiment, and may be embodied with the following modifications. (1) In the present embodiment, the fluid supply / discharge member 4 is configured by connecting the connection blocks 7a to 7e, the introduction block 8 and the derivation block 9 with the connection tool 10. However, each block 7a to 7e is connected. , 8 and 9 may be integrally formed to configure the fluid supply / discharge member 4. In this case, the connector 10 can be omitted, and the labor for connecting the blocks 7a to 7e, 8, 9 can be omitted when manufacturing the fluid supply / discharge member 4.

(2) In the present embodiment, the dehumidifying unit 6 that dehumidifies the air using the hollow fiber is illustrated, but the present invention is not limited to this. That is, instead of the dehumidifying member 25 composed of a large number of hollow fibers, a dehumidifying unit may be used in which a moisture adsorbent that adsorbs moisture in the air is housed in the cylinder 21 and the moisture adsorbent dehumidifies the moist air.

(3) In this embodiment, the two dehumidifying units 6 are respectively suspended and fixed to the connecting blocks 7a to 7e, but the number of dehumidifying units 6 to be suspended and fixed is not limited to this embodiment. That is, one dehumidifying unit 6 may be suspended and fixed to each of the connection blocks 7a to 7e, or three or more dehumidifying units 6 may be suspended and fixed.

(4) In this embodiment, the fluid supply / discharge member 4 is provided with the five connecting blocks 7a to 7e, but the number of connecting blocks may be changed as appropriate.
