Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dehumidifying device for gas, and particularly to a dehumidifying device for compressed air and the like.

Conventionally, in a compressed air dehumidification device, as shown in FIG. It consists of another sill plate 7 provided with a notch 6 for air passage. A heat transfer tube 8 for passing a refrigerant for cooling compressed air is further arranged inside the container 3, and a wire mesh 10 is provided at the bottom of the container 3 to hold water separated from the air and guide it to a drain outlet 9. It is being

Further, a discharge valve 11 is attached to the discharge port 9.

In the conventional dehumidifier as described above, the inlet 1
The humid compressed air introduced into the container 3 from above passes through the through hole 4 of the board 5 in the direction A, and
It collides with the wall plate 7, gives some of the moisture as moisture to the wall surface of the plate 7, is bent in the direction B, and then passes through the gap between the notch 6 and the inner wall of the container 3 in the direction C to the next stage. Reach Yamaita 5. After repeating this process, the compressed air is dehumidified and flows out through the outlet 2. In addition, the water that is cooled by the refrigerant in the heat exchanger tubes 8 and condenses also adheres to the periphery of the heat exchanger tubes 8, the wall surface of the container 3, and the baffle plates 5, 7.
removed from compressed air. These moistures are
It gradually descends and accumulates in the wire mesh 10 at the bottom of the container 3, and is discharged from the outlet 9 on the inlet 1 side as desired. However, since the baffle plate 7 on which the compressed air that has passed through the through-hole 4 collides is configured in a flat plate shape, the contact time with the air baffle plate 7 is short;
Not only is the water separation ability of the barrier board 7 low, but there is also a risk that the water that has already adhered and separated on the flat wall surface of the barrier board 7 may be re-engulfed into the new compressed air flow. In addition, a portion of the compressed air flow that collided with the flat wall plate 7 moves downward, that is, in the D direction, collides with the wire mesh 10, and returns upward.
At this time, there is a risk that the air flow may wind up the separated moisture present in the wire mesh 10 and carry it away in a mist state. When this mist flows out from the outlet, the temperature of the compressed air in the pipe (not shown) increases and the mist is again retained in the compressed air as water vapor.

Therefore, conventional dehumidification devices cannot necessarily be expected to have a sufficient dehumidification effect.

Furthermore, in the conventional dehumidifier, a discharge port 9 for the separated water is provided on the inlet 1 side. However, because the static pressure of the compressed air inside the container 3 on the inlet 1 side is higher than that inside the container 3 on the outlet 2 side, most of the separated water accumulates on the outlet 2 side. . There is a possibility that the water may not necessarily be sufficiently discharged from the discharge port 9.

The present invention was created in view of the above points,
The purpose is to provide a dehumidifying device with a high dehumidifying effect.

The object is to provide a first wall board according to the present invention, which is arranged in a container that communicates an inlet and an outlet of gas, and has a through hole through which the gas passes; a second cutting board disposed in the container downstream in the gas passage direction;
The second dipping board includes a recess opened toward the through hole to accommodate the gas, a draining plate disposed within the recess to allow moisture in the gas to adhere, and the drainer. This is achieved by a dehumidifying device having a liquid discharge passage connected to the recess attached to the plate for discharging the moisture accumulated in the recess.

Next, a preferred embodiment of the present invention will be explained based on the drawings. The same members as in FIG. 1 are designated by the same reference numerals.

In the figure, a wall plate 5 having a through hole 4 inside a container 3
A gas reservoir 1 is located in the lower part of the through hole 4.
2 is provided. A notch 14 is provided in the jiyama board 13 in the same way as in the jiyama board 7.
is provided.

The number and arrangement of the notches 14 are determined as desired, and for example, they are provided at four locations as shown in FIG. Any number of pairs of the jamb board 5, the jamb board 13, and the blank board may be provided as desired.

The gas reservoir portion 12 includes a recess 15 that is formed in the wall plate 13 and opens toward the through hole 4 to accommodate gas that is a compressed air flow, and a drain plate 16 that is fixed to the recess 15 at one end. Become. The recess 15 may be formed into a cylindrical shape with one end closed, for example, and even if it is formed integrally with the second wall board 13 as in this specific example, it may be formed separately from the second wall board 13. It may be formed of the member. The drain plate 16 is formed, for example, into a truncated conical tube. The draining plates 16 may be formed from two or more sheets, and in that case, the two or more draining plates 16 may be integrally formed.

Although the shape of the draining plate 16 is determined as desired, it is formed in such a shape that there are few portions where gas remains in the chamber 17 formed by the recess 15 and the draining plate 16. Further, an opening 18 is provided at a portion of the draining plate 16 facing the through hole 4 in order to reliably introduce the compressed air flow passing through the through hole 4 in the direction A into the chamber 17. Furthermore, the chamber 17 is formed in such a shape that the compressed air flow becomes turbulent within the chamber 17, and the compressed air laden with humidity is transferred to the band area 15.
When the compressed air violently collides with the bottom surface 19, the inner wall surface 20, etc. of the drain plate 16, the compressed air is dehumidified within the gas reservoir 12 by imparting moisture to the bottom surface 19, inner wall surface 20, etc. of the drain plate 16. Note that even if air compression waves such as vibration noise in the compressed air are propagating, the compressed air may
The compression waves are disturbed by violently colliding with the bottom surface 19 and the inner wall surface 20 within the chamber 7, and turbulence is generated, and the compression waves are confined within the chamber 17 for a relatively long time, so that the sound energy is transferred to the bottom surface 19. and absorbed by the inner wall surface 20. Therefore, the gas reservoir can also have a noise-muffling effect.

Since the dehumidified airflow exiting from the opening 18 of the gas reservoir 12 is in a turbulent state, there is almost no flow in the D direction compared to the flow in the E direction.
Therefore, there is little risk that the separated water in the wire mesh portion 10 will be rolled up.

A through hole 21 is provided at the lower end of the draining plate 16, and a groove 23 is provided in a portion 22 of the cutting board 13 below the recess 15. Through hole 2
1 and the groove 23 form a separate water discharge passage. That is, the moisture adhering to and separating from the bottom surface 19 and the wall portion 20 descends, passes through the through holes 21 and the grooves 23, and reaches the wire mesh 10 at the bottom of the container 3.

Instead of forming the recess 15 with the jamb plate 13, it may be formed with a separate member, and the gas reservoir portion 12 is
It may consist only of the wall board 13 having the recess 15, or it may consist only of the flat wall board 13 and a separate member forming the recess, for example, a draining board 16 similar in shape to the one in this specific example. You can leave it there.

Moisture in the compressed air is removed not only by contact with the wall surface etc. in the gas reservoir 12 and cooling by the heat exchanger tubes 8, but also by contact with the perforated plate 24.

The perforated plate 24 has a large number of small-diameter through holes 25 and is disposed in the compressed air passage near the outlet 2 of the container 3, so that no air remains in the compressed air passing through while contacting the inner wall of the through holes 25. Remove moisture.

Moisture adhering to the porous plate 24 also descends and reaches the wire mesh 10. Note that if a large amount of moisture adheres to the through holes of the perforated plate 24, this moisture may be drawn into the air flow again, so it is preferable that the perforated plate 24 be brought into contact with the compressed air flow after most of the dehumidification has been performed. . The perforated plate 24 is therefore arranged downstream in the path of the air flow in the container 3. Furthermore, by arranging the perforated plate 24 near the outlet 2,
The airflow that has become turbulent in the container 3 can be brought closer to a laminar flow, and as a result, the airflow can flow smoothly in the piping extending from the outlet 2. In other words, it becomes possible to increase the dehumidification rate within the container 3.

The drain outlet 26 is provided at the most downstream side within the container 3. On the downstream side, the static pressure of the compressed air is lower than on the upstream side of the container, so water accumulated in the wire mesh 10 at the bottom of the container 3 can be effectively discharged. Above the discharge port 26 is another perforated plate 27.
is installed. The perforated plate 27 prevents moisture in the vicinity of the wire mesh 10 from being rolled up toward the outlet 2 by the compressed air flow, and also prevents moisture from splashing into the compressed air flow when draining from the drain outlet 25. It is prevented.

In the dehumidifying device 28 configured as described above, since the second barrier plate 13 having the recess 15 is provided in the portion facing the through hole 4 of the first barrier plate 5, the recess 15 Since the drain plate 16 is provided in the recess 15, the dehumidification function is improved, and there is no fear that the water separated at the bottom of the container 3 will be rolled up, extending radially from the gas reservoir 12. Since the liquid discharge passages 21 and 23 are provided, the separated moisture can be quickly guided to the bottom of the container, and the porous plate 24 that allows gas to pass through is provided downstream of the gas flow path, further improving the dehumidification function. Furthermore, since another perforated plate 27 is provided at the bottom of the container opposite to the drain outlet 26, there is no fear that the separated water will be blown up again. Since the heat transfer tube 8 through which the refrigerant passes is provided, the dehumidification effect can be further improved.

As described above, in the dehumidifier of the present invention, dehumidification can be performed by the recess that opens toward the through hole of the first board and is provided in the second board. The dehumidification function can be further improved by the drain plate, and there is no fear that the water separated at the bottom of the container will be rolled up by the drain plate. Also,
Since a liquid discharge passage connected to the recess is provided in the second drain plate, the water separated from the gas and deposited on the drain plate and the recess is quickly led to the bottom of the container.

Therefore, the dehumidifier of the present invention can perform efficient dehumidification without fear of re-rolling up the separated moisture.
