A plurality of dehumidifying units 75 are arranged between the four, and the lower part of each dehumidifying unit 75 is fixed by a plurality of lower bolts 76 screwed from the lower surface of the fluid discharge member 72.
Note that a gap having a width of a distance L is formed between the installation surface of the dehumidifier 1 and the lower surface of the fluid discharge member 72 by the support leg 73,
This gap allows the operator to loosen the lower bolt 76 with a spanner or the like.

The two columns 74 support a fluid supply member 77, and the lower surface of the fluid supply member 77 has a plurality of dehumidifying units 75.
Abuts on the upper end of the 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 both upper and lower ends by the lower bolt 76 and the upper bolt 78.

A fluid inlet 79 for introducing humid air to the dehumidifier 71 is provided on one side of the fluid supply member 77, and the fluid inlet 79 communicates with a fluid supply port of each dehumidifying unit 75. I have. A fluid outlet 80 is provided on one side of the fluid discharge member 72 for leading dry air after dehumidification from the dehumidifier 71. The fluid outlet 80 is a fluid outlet of each dehumidifying unit 75. Is in communication with

Therefore, the humid air introduced into the dehumidifier 1 from the fluid inlet 79 is supplied to each dehumidifying unit 75 through the fluid supply port, and is dehumidified by each dehumidifying unit 75 to become dry air. After the dry air is discharged from the dehumidifying unit 75 through the fluid discharge port, the dry air is discharged from the fluid discharge port 80.
From the dehumidifier 1 to the outside.

A purge air passage 25a is formed by a gap between the hollow fibers constituting the dehumidifying member 25. A purge air outlet 21a is formed in the cylinder 21 to communicate the purge air passage 25a with the outside of the dehumidification unit 6.

Next, the lower end of the cylindrical body 21 is fitted with an opening of a cap 31 formed in a cylindrical shape with a bottom.
A third seal member 31a is provided on the fitting surface on one side. 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 a lower end of the communication pipe 26 to communicate the fluid outlet chamber 32 with the inside of the communication pipe 26. Further, the communication pipe 26 is connected to the communication pipe 26 and the purge air passage 25.
and a purge air inlet 26a communicating with the purge air inlet 26a.

Therefore, the humid air is supplied from the fluid introduction passage 12 to the fluid introduction chamber 30 of the dehumidification unit 6 through the fluid supply port 13, and further flows through the hollow fibers constituting the dehumidification member 25. Has become. Then, the humid air is dehumidified inside the hollow fiber to become dry air. This dry air is sent out to the fluid outlet chamber 32, and further, the communication pipe 2
The fluid is sent to the fluid outlet passage 15 through the fluid outlet 6 and the fluid outlet 16.

A part of the dry air passing through the communication pipe 26 is supplied to the purge air passage 25a through the purge air inlet 26a. When the dry air passes through the purge air passage 25a, that is, the outside of each hollow fiber constituting the dehumidifying member 25, the humid air flowing inside each hollow fiber is dehumidified by the action of the permeable membrane.

Next, the dehumidifier 1 configured as described above
The operation of will be described. First, when the humid air is supplied to the fluid intake passage 11 of the fluid supply / discharge member 4, the humid air flows through the fluid introduction passage 12 and passes through the fluid supply ports 13 of the connection blocks 7a to 7e. 6 is introduced into the fluid introduction chamber 30. The moist air introduced into the fluid introduction chamber 30 is
The inside of each hollow fiber constituting the dehumidifying member 25 is connected to the fluid introduction chamber 3
The fluid flows from the zero side toward the fluid outlet chamber 32 side.

At this time, the moisture contained in the humid air penetrates into the hollow fiber itself and is separated from the humid air. As a result, the humid air is dehumidified to become dry air. After passing through the hollow fiber, the dry air is sent to the fluid outlet chamber 32, 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 out to the fluid outlet passage 15 is led out of the fluid supply / discharge member 4 via the fluid outlet passage 14.

A part of the dry air flowing through the communication pipe 26 is sent to a purge air passage 25a through a purge air inlet 26a. The dry air flowing through the purge air passage 25a becomes moist air by taking in the moisture permeating the hollow fiber into the gas, and the moist 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 bolts 24 fixing the dehumidifying unit 6 to the dehumidifying device 1 are loosened. Then, the fixing of the dehumidifying unit 6 is released, and the dehumidifying unit 6 can be removed. When the dehumidifying unit 6 is pulled downward in this state, the upper end of the cylindrical body 21 comes off the concave portion 20, and the upper end of the communication pipe 26 comes off the fluid discharge port 16,
As shown in FIG. 4, the dehumidifying unit 6 is removed from the dehumidifying device 1. Also, the lower end of the dehumidifying unit 6 and the base 1a
Since a gap having a width of the distance L is formed between the dehumidifying unit 6 and the upper surface, 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 cylindrical body 21 is fitted into the concave portion 20 and the upper end of the communication pipe 26 is fitted into the fluid outlet 16. This fitting is easily performed by a gap provided between the dehumidifying unit 6 and the base 1a. In this state, the upper end surface of the cylindrical body 21 contacts the upper surface of the concave portion 20,
A fixing bolt 24 is screwed from the upper surface of the fluid supply / discharge member 4. The dehumidifying unit 6 is fixed to the dehumidifying device 1 by screwing the fixing bolt 24.

As described in detail above, in the present embodiment, the dehumidifying unit 6 is suspended and fixed to the fluid supply / discharge member 4 only by the fixing bolt 24. Accordingly, when the dehumidifying unit 6 is to be removed, it is only necessary to loosen the fixing bolt 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 related art, the width of the gap, that is, the gap, that is,
It is not necessary to make the distance L large enough for the operator to reach. Therefore, the distance L can be reduced, and the space saving of the dehumidifier 1 is improved.

In the present embodiment, the connecting blocks 7a to 7e 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 the dehumidifying units 6 can be freely set according to the flow rate of the humid air. That is, when increasing the number of dehumidifying units 6, the number of connecting blocks may be increased, and when reducing the number of dehumidifying units, the number of connecting blocks may be decreased.

It should be noted that the present invention is not limited to the above embodiment, but may be embodied with the following modifications, for example. (1) In this 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.
The fluid supply / discharge member 4 may be formed by integrally forming a to 7e, 8, and 9. In this case, the connector 10 can be omitted, and when manufacturing the fluid supply / discharge member 4, the labor for connecting the blocks 7 a to 7 e, 8, and 9 can be saved.

(2) In the present embodiment, the dehumidifying unit 6 for dehumidifying air using hollow fibers has been exemplified, 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 that accommodates a moisture adsorbent that adsorbs moisture in the air in the cylindrical body 21 and dehumidifies wet air with the moisture adsorbent may be used.

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

(4) In the present embodiment, 5
Although the two connection blocks 7a to 7e are provided, the number of connection blocks may be appropriately changed.
