Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a gas exchange device. More specifically, the present invention relates to a gas exchange device for supplying a dry gas and discharging a gas containing water vapor.

[0002]

2. Description of the Related Art A gas exchange device for supplying a dry gas to one end of a moisture absorbent and discharging the wet gas to the other end by using a disk-shaped moisture absorbent having a large number of through holes extending in an axial direction. Has been conventionally developed. The disk-shaped moisture absorber used in this gas exchange device generally has a large number of through holes extending in the axial direction and communicating with both end surfaces of the disk-shaped moisture absorber. The surface of the through hole is configured to adsorb moisture contained in the air passing through the through hole.

That is, in this gas exchange device, the moisture contained in the wet air at the other end is adsorbed on the surface of the hole so that the wet air at the other end of the moisture absorber passes through the through hole. By adsorbing the moisture contained in the humid air on the surface of the through hole, the humid air can be supplied to one end side as dry air. However, when a certain amount or more of water is adsorbed on the surface of the through hole of the moisture absorbent, the through hole that has adsorbed the moisture can no longer newly adsorb moisture.

[0004] Therefore, the gas exchange device allows the dry air on one end side of the moisture absorber to pass through the through hole, absorbs the moisture adsorbed on the surface of the through hole into the dry air, and cleans the surface of the through hole. Have been dried. When the surface of the through-hole is dried, the through-hole can newly absorb moisture. When the surface of the through-hole is dried with such dry air, the dry air absorbs moisture and becomes moist air, so the gas exchange device usually discharges the moist air to the other end. ing.

[0005] In this case, the gas exchange device conventionally introduces air that is moist from the other end surface other than the fan-shaped end surface of the other end surface into the through hole while rotating the disc-shaped moisture absorber. Adsorbs moisture contained in moist air on the surface and supplies dry air to one end, and introduces dry air from a fan-shaped end surface at a predetermined angle from the rotation center of the end surface on one end side of the hygroscopic body into the through hole The through-hole adsorption performance is regenerated. By rotating the disc-shaped hygroscopic body in this way, the gas exchange device can alternately and continuously repeat the adsorption of moisture by the through holes and the regeneration of the adsorption performance of the through holes.

[0006]

As described above, in the conventional gas exchange apparatus, the air at the other end is dehumidified by the through hole to supply dry air to one end, and the dry air at the one end is supplied to the through hole by the dry air. The inside is dried to regenerate the adsorption performance of the through-hole, and the resulting moist air is discharged to the other end.

As a method of improving the dehumidifying ability of such a gas exchange device, there is a method of using an adsorbent having high adsorption performance on the surface of the through-hole. For example, Japanese Patent Application Laid-Open No. 54-19548 discloses a hygroscopic body having a columnar honeycomb structure using a hygroscopic agent containing molecular sieve powder. Japanese Unexamined Patent Publication No. 63-240921 discloses that a moisture absorbent mainly composed of silica gel is used for an introduction side area of a through hole to which a wet gas is introduced, and that a dry gas is introduced to an exit side area of a through hole. A hygroscopic body having a columnar honeycomb structure using a hygroscopic agent whose main component is zeolite is disclosed. These are techniques for improving the dehumidifying ability of the gas exchange device by using a moisture absorbent having a high moisture adsorption performance.

[0008] Further, it is conceivable to improve the dehumidifying ability of the gas exchange device by increasing the amount of the moisture absorbent used on the surface of the through hole.

The method of increasing the amount of the hygroscopic agent and the method of using a hygroscopic agent having a high moisture adsorption performance are certainly effective.

However, the technique of increasing the amount of the moisture absorbent increases the size of the moisture absorbent itself in which the moisture absorbent is used. As a result, the manufacturing cost increases, and the place where the moisture absorbent can be installed is limited. Furthermore, since the disk-shaped moisture absorber is rotated, the energy required for rotating the moisture absorber is increased by increasing the size of the moisture absorber.

The method of using a hygroscopic agent having a high moisture adsorption performance also cannot improve the dehumidifying ability of the gas exchange device unless the hygroscopic agent adsorption performance can be effectively exhibited. Even in the method of increasing the amount of the hygroscopic agent, if the adsorption performance of the hygroscopic agent is not effectively exhibited, no matter how much the amount of the hygroscopic agent is increased, the dehumidifying ability of the gas exchange device cannot be eventually improved.

Accordingly, it is an object of the present invention to provide a gas exchange device capable of efficiently adsorbing moisture.

[0013]

As a result of intensive studies, the present inventor has made a first disk-shaped disk having a large number of through holes extending in the axial direction.
The first moisture absorber, the disc-shaped second moisture absorber having a plurality of axially extending through holes arranged in the axial direction and the first moisture absorber, and the first moisture absorber and the second moisture absorber are mutually connected. A driving means for rotating in the opposite direction, and sending the gas on one end side from a fan-shaped end surface at a predetermined angle from the rotation center on one end side of the first moisture absorber and the second moisture absorber arranged in the axial direction, The present invention has invented a gas exchange device comprising: gas exchange means for sending gas at the other end side from the other end face other than the fan-shaped end face at the other end side of the first moisture absorber and the second moisture absorber.

The gas exchange device introduces gas at one end from a fan-shaped end face at a predetermined angle from the rotation center at one end side of the moisture absorber, thereby drying the through-hole at the fan-shaped end face and drying the through-hole. The adsorption performance is regenerated.
Therefore, the portion where the through hole where the adsorption performance has been reproduced is located is a portion that has passed through a fan-shaped end face having a predetermined angle, and the through hole in this portion can exhibit the adsorption performance most. Further, the through-hole at a portion before reaching the fan-shaped end surface at a predetermined angle is a through-hole which has already adsorbed moisture and lowered the adsorbing performance. Therefore, it is considered that the through-hole in this portion cannot sufficiently exhibit the adsorption performance.

In the conventional gas exchange device, one disk-shaped moisture absorber is rotated, and the adsorption of moisture and the regeneration of the adsorption performance are alternately and continuously repeated. Alternatively, when two disk-shaped moisture absorbers are used, the two moisture absorbers are rotated in the same direction, and the adsorption of moisture and the regeneration of the adsorption performance are alternately and continuously repeated. Therefore, the through hole regenerated by passing through the fan-shaped end face moves to only one side of the fan-shaped end face because the moisture absorber rotates only in one direction.

On the other hand, the gas exchange device of the present invention rotates the disk-shaped first moisture absorber and the disk-shaped second moisture absorber arranged in the axial direction in opposite directions. In this way, the portion of the through-hole where the adsorption performance has been regenerated by passing through the fan-shaped end face moves in the direction opposite to the fan-shaped end face between the first moisture absorber and the second moisture absorber. That is, the portion where the moisture absorption performance of the first moisture absorber is regenerated and the portion where the moisture absorption performance of the second moisture absorber is regenerated move to both sides of the fan-shaped end surface. Therefore, in the gas exchange device of the present invention,
The portion capable of exhibiting the moisture absorbing performance is spread on both sides of the fan-shaped end face. As a result, the gas exchange device of the present invention can dehumidify moisture in the air by efficiently utilizing the adsorption performance of the through holes.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the gas exchange apparatus according to the present invention will be described below.

The gas exchange apparatus of the present invention has a disk-shaped first moisture absorber having a plurality of axially extending through holes, and a plurality of axially extending through holes arranged in the axial direction with the first moisture absorber. A disk-shaped second moisture absorber, driving means for rotating the first moisture absorber and the second moisture absorber in opposite directions, and one end of the first moisture absorber and the second moisture absorber arranged in the axial direction Gas exchange by sending a gas at one end from a fan-shaped end surface at a predetermined angle from the rotation center on the side, and sending a gas at the other end from the other end surface other than the fan-shaped end surface at the other end of the first and second moisture absorbers. Means.

The first disc-shaped moisture absorber and the second disc-shaped moisture absorber are arranged in the axial direction, and each has a large number of through holes extending in the axial direction. This through hole communicates both end surfaces of the moisture absorbent. Here, the term "disk-shaped" includes those in which the axial lengths of the first moisture absorber and the second moisture absorber are long and thus have a shape such as "columnar shape".

The first moisture absorber and the second moisture absorber have a large number of through holes extending in the axial direction. It is preferable that the first moisture absorber and the second moisture absorber are formed of a honeycomb. It is also preferable that the first moisture absorber and the second moisture absorber are formed from a honeycomb-shaped substrate and a moisture absorbent formed on the surface of the substrate.

The diameter of the through hole is determined so that the gas contained in the gas is brought into contact with the surface of the through hole to allow the water contained in the gas to be adsorbed to the through hole or to absorb the moisture adsorbed to the through hole. It can be a suitable diameter. The diameter of the through hole is approximately 0.5 to 10 mm
It can be.

The axial lengths or thicknesses of the first moisture absorber and the second moisture absorber are suitable for absorbing moisture contained in a gas or absorbing moisture absorbed in a through hole. Length. The longer the through hole, the greater the proportion of air that contacts the surface of the through hole. Therefore, the moisture in the air can be adsorbed accordingly. However, if the holes are made longer than necessary, there will be portions of the holes that no longer adsorb moisture. Also, the energy required for the gas exchange means for sending gas to the opposite end face increases. On the other hand, if the length of the through hole is too short, the gas at the other end will be supplied to one end before moisture is adsorbed. The first moisture absorber and the second moisture absorber may each be approximately 15 to 100 mm.

The greater the number of through holes provided in the first and second moisture absorbers, the greater the amount of gas introduced into the moisture absorber. Therefore, a large amount of gas can be dehumidified. Therefore, it is preferable that the first moisture absorber and the second moisture absorber have a configuration having many holes like a honeycomb, that is, a honeycomb. By using a honeycomb, the number of through holes per unit area of the end face increases, and the amount of air introduced into the moisture absorbent can be increased. As a result, more gas can be dehumidified.

The first moisture absorber and the second moisture absorber are ceramic paper kneaded with a hygroscopic agent such as silica or zeolite,
A corrugated plate made of fiber paper or the like and a flat plate can be stacked. It can also be manufactured by sintering a mixture of cordierite or the like and a moisture absorbent. Also, when the first moisture absorber and the second moisture absorber are formed into a honeycomb, they can be manufactured by laminating a corrugated plate and a flat plate, or by sintering. It can also be manufactured by press working, extrusion working, or the like. In these cases, the first moisture absorber and the second moisture absorber can be configured as a base and a hygroscopic agent formed on the surface of the base. That is, the first moisture absorber and the second moisture absorber can be manufactured by forming a base having a large number of through holes extending in the axial direction and a hygroscopic agent on the surface of the base. By forming a moisture absorbent on the surface of the base, moisture in the air that has passed through the through hole and has come into contact with the surface of the through hole can be efficiently adsorbed.

In this case, it is preferable that the first moisture absorber and the second moisture absorber include a honeycomb-shaped base and a hygroscopic agent formed on the surface of the base. By using a honeycomb-shaped substrate, the number of through-holes per unit area of the end face increases, and the amount of air introduced into the moisture absorbent can be increased. As a result, more gas can be dehumidified.

The honeycomb-shaped bases of the first and second moisture absorbers can be formed using a metal plate, for example, a plate of aluminum, stainless steel or the like. Further, it can be configured using ceramic paper or the like. For example, a honeycomb-shaped substrate can be formed by laminating a flat plate and a corrugated plate alternately to form a winding. As a material used for the flat plate and the corrugated plate, a metal plate such as aluminum and stainless steel, a ceramic paper and the like can be used. However, it is not limited to these.

When aluminum, stainless steel or ceramic paper is used as the honeycomb substrate, it is preferable to use a thin plate or foil of aluminum, stainless steel, ceramic paper or the like. The pressure loss can be reduced by using these materials.

As a moisture absorbent formed on the surface of these substrates, zeolite, silica, alumina and the like can be used. Even when the temperature reaches 100 ° C. or higher by the regenerative heater, there is no danger of ignition due to the inorganic material. However, it is not limited to these.

In this case, when forming the moisture absorbent on the substrate surface, a binder can be used together with the moisture absorbent.
For example, binders such as silica sol and alumina sol and mineral binders can be appropriately used according to the type of the moisture absorbent. However, it is not limited to these.

The disc-shaped first moisture absorber and the disc-shaped second moisture absorber can be the same moisture absorber. It is also possible to use different materials of the same shape. For example, moist air is used as a moisture absorber on the side where it is first introduced, that is, a second moisture absorber that can exhibit adsorption performance in the case of high humidity, and is adsorbed even in the case of low humidity as the first moisture absorber. It is also possible to use a moisture absorbent that can exhibit performance. Further, the axial lengths of the first moisture absorber and the second moisture absorber can be set differently. It can be determined appropriately in consideration of the material used.

Further, the gas exchange device of the present invention is provided with a driving means for rotating the first moisture absorber and the second moisture absorber in directions opposite to each other. This driving means can be configured using a motor or the like. That is, the disc-shaped first moisture absorber and the second
A central axis can be provided for each of the moisture absorbers, and the central axis can be rotated by a motor or the like. Further, a belt may be hung on the side wall surface of the disc-shaped first and second moisture absorbers and the rotating shaft of the motor, and the rotation of the motor may be transmitted to the first and second moisture absorbers to rotate them. it can. In this way, while the first moisture absorber and the second moisture absorber are rotated in the opposite directions by the driving means, the gas exchange means described below is used to rotate one end of the first moisture absorber and the second moisture absorber arranged in the axial direction. By sending gas on one end side from the fan-shaped end face at a predetermined angle from the rotation center and sending gas on the other end side from the other end face other than the fan-shaped end face on the other end side of the first and second moisture absorbers, While regenerating the adsorbing performance of the through-hole at the fan-shaped end surface at a predetermined angle from the rotation center on the side, it is continuous that water is adsorbed by the through-hole at the other end surface other than the fan-shaped end surface at the other end. Can be done.

In this case, the disc-shaped first and second moisture absorbers can be rotated in opposite directions at the same cycle. It can also be rotated in different directions at different periods. For example, when the first moisture absorber and the second moisture absorber have different lengths in the axial direction, they are rotated at different periods so as to be proportional to the lengths of the through holes, thereby setting the time at which the fan-shaped end face is located. be able to.

Further, the gas exchange device of the present invention sends the gas on one end side from a fan-shaped end surface at a predetermined angle from the rotation center on one end side of the first and second moisture absorbers arranged in the axial direction. Gas exchange means for sending gas on the other end side from the other end face other than the fan-shaped end face on the other end side of the moisture absorbent and the second moisture absorbent is provided. This gas exchange means can be configured using a blower. That is, the blower is arranged at a position facing the fan-shaped end face at a predetermined angle from the rotation center on one end side of the first moisture absorber and the second moisture absorber, and blows gas on one end side and introduces the gas into the through hole of the fan-shaped end face. can do. Further, a blower is disposed at a position facing the other end face other than the fan-shaped end face on the other end side of the first moisture absorber and the second moisture absorber, and the other end face other than the fan-shaped end face is blown by blowing gas on the other end side. It can be introduced into the through hole.

It is also possible to use a suction device as gas exchange means. To send the gas at one end from the fan-shaped end face at a predetermined angle from the rotation center at one end using a suction machine, install the suction machine at a position facing the fan-shaped end face at a predetermined angle from the rotation center at the other end. Thus, the gas at one end can be sent. In order to send gas on the other end side from the other end face other than the fan-shaped end face on the other end side, a suction device can be installed at a position facing the other end face other than the one-end fan-shaped end face. Further, a blower and a suction device can be used in combination.

When a fan-shaped end face at a predetermined angle from the center of rotation is provided on the first moisture absorbing body side, the other end face other than the fan-shaped end face is provided on the second moisture absorbing body side. Conversely, when a fan-shaped end face is provided on the side of the second moisture absorber, the other end face other than the fan-shaped end face is provided on the side of the first moisture absorber.

In this case, it is preferable that a partition plate for partitioning the fan-shaped end face and the other end face other than the fan-shaped end face be disposed on the end face.

The wind speed at the time of sending the gas can be set to an appropriate wind speed. It can be approximately 0.5 to 10 m / s, preferably 1 to 3 m / s. 10m / s
If it exceeds, gas will blow through. 0.5m / s
If it is less than 1, the effect of dehumidifying the moisture in the air or regenerating the adsorption performance is hardly obtained because the gas transmission speed is low.

Further, it is preferable to use a blower for supplying gas to the fan-shaped end face as the gas exchange means and to use a heating means for heating the gas blown by the blower. When the gas is introduced into the through hole from the fan-shaped end surface and the inside of the through hole is dried to regenerate the moisture adsorption performance, the inside of the through hole is further dried by introducing the heated gas into the inside of the through hole. Thus, the adsorption performance can be regenerated. In this case, a normal heater or the like can be used as the heating means. Therefore, a heater can be arranged between the blower and the fan-shaped end face to supply heated gas to the fan-shaped end face. In this case, the temperature of the heater can be set to an appropriate temperature according to the material used for the moisture absorber. It can be set to approximately 80 to 300 degrees.

The ratio of the area of the fan-shaped end face to the area of the other end face other than the fan-shaped end face can be approximately 1:35 to 1: 1. That is, the angle of the fan-shaped end face can be set to 10 to 180 degrees. If the area of the fan-shaped end face is small, it becomes difficult to regenerate the desiccant, and if the area of the fan-shaped end face is large, the portion that adsorbs moisture is reduced. In this case, the area ratio, that is, the area of the fan-shaped end face: the area of the other end face other than the fan-shaped end face is preferably 1: 2 to 1: 4.

As described above, by dividing the fan-shaped end face and the other end face other than the fan-shaped end face at an appropriate ratio, the adsorption performance of the first moisture absorber and the second moisture absorber is regenerated, and the first moisture absorber and the second moisture absorber are separated.
Adsorption of moisture by the hygroscopic body can be performed in a well-balanced manner.

In the gas exchange apparatus of the present invention thus configured, the first moisture absorber and the second moisture absorber are rotated in the opposite directions by the driving means, and are rotated from the fan-shaped end face at one end by the gas exchange means. The gas on one end side can be sent to the other end side, and the gas on the other end side can be sent to one end side from the other end face other than the fan-shaped end face on the other end side. In this way, the gas on one end side is introduced from the fan-shaped end surface on one end side, the through holes in the fan-shaped end surface portion are dried to regenerate the adsorption performance, and as a result, the gas containing water vapor on the other end side Can be discharged.
In addition, by sending the gas on the other end side to the one end side from the other end face other than the fan-shaped end face on the other end side, the moisture contained in the gas on the other end side is adsorbed to the holes and dried air is dried on one end side. Can be supplied to In the gas exchange device of the present invention, since the first moisture absorber rotates the second moisture absorber, the dehumidification of the moisture and the regeneration of the adsorption performance can be alternately and continuously performed.

Also, in the gas exchange device of the present invention, the first moisture absorber and the second moisture absorber rotate in directions opposite to each other. Each will move in the opposite direction. That is, the areas of the portions that are located on the opposite sides of the fan-shaped end faces and are reproduced accordingly expand to both sides of the fan-shaped end faces. Therefore, moisture contained in the gas can be adsorbed more efficiently.

Disc-shaped first moisture absorber 1 arranged in the axial direction
The 0 and the disc-shaped second moisture absorber 20 are the same disc-shaped moisture absorber, and include a honeycomb-shaped base and a hygroscopic agent formed on the surface of the base. Accordingly, both the first moisture absorber 10 and the second moisture absorber 20 have a diameter of 250 mm and an axial length of 25 mm. FIG. 2 shows a part of the disk-shaped moisture absorber used as the first moisture absorber 10 and the second moisture absorber 20 in a section perpendicular to the axis.

Each of the honeycomb-shaped substrates constituting the first and second moisture absorbers 10 and 20 has a flat plate 40 and a corrugated plate 50 around a core pipe 30 having a diameter of 30 mm and a thickness of 1 mm.
And a honeycomb-shaped substrate formed in a disc-like shape having a diameter of 250 mm by alternately overlapping in a winding pattern. Each of the honeycomb-shaped substrates thus configured has a large number of through-holes 70 extending in the thickness direction, that is, the axial direction, with both end surfaces communicating with each other. In other words, the gap between the flat plate 40 and the corrugated plate 50 that are alternately stacked in a spiral shape is configured as the through hole 70.

Then, by drying the honeycomb-shaped substrate having the slurry attached to the surface thereof at a temperature of 200 ° C., the slurry attached to the surface of the honeycomb-shaped substrate is dried and solidified to form the carrier layer 60. The supporting layer 60 is thus formed on each of the honeycomb-shaped base constituting the first moisture absorber 10 and the honeycomb-shaped base constituting the second moisture absorber 20. The supporting layer 60 of the first moisture absorber 10 and the second moisture absorber 20 formed as described above.

In the present embodiment, the first moisture absorber 10 is set to rotate clockwise when viewed from the left side, and the second moisture absorber 20 is set to rotate in the opposite direction at the same cycle.

The gas exchange device 100 of the present embodiment is configured to remove the air at one end from the fan-shaped end surface 11 at a predetermined angle from the rotation center at one end of the first moisture absorber 10 and the second moisture absorber 20 arranged in the axial direction. There is provided a gas exchange means for sending air from the other end face (not shown) other than the fan-shaped end face on the other end side of the first moisture absorber 10 and the second moisture absorber 20 to the other end side. In this embodiment, a partition plate 80 is provided in front of the left end surface of the first moisture absorber 10 to divide the end surface of the first moisture absorber 10 into a 90-degree fan-shaped end surface 11 about the rotation center. That is, the partition plate 80 divides one end face, that is, the left end face, of the first moisture absorber 10 into a 90-degree fan-shaped end face 11 and another end face other than the fan-shaped end face at an area ratio of 1: 3. Further, a partition plate (not shown) is provided at a position corresponding to the partition plate 80 provided on the right end surface of the second moisture absorber 20 before the left end surface of the first moisture absorber 10, that is, at a position occupying the same phase. .

In this embodiment, the first moisture absorber 1
The heater 90 is located at a position opposite to the fan-shaped end surface 11 occupying 1/4 of the left end surface of the fan 0, that is, on the left side (front side) of the fan-shaped end surface 11.
Is arranged. Further, a blower (not shown) is provided on the left side of the heater 90. The air on the left side of the first moisture absorber 10 from the fan-shaped end face 11 of the first moisture absorber 10 arranged in the axial direction by the blower is moved to the second moisture absorber 20.
Can be sent to the right. In this case, the air sent by the blower is heated by the heater 90, and the heated air is sent from the fan-shaped end surface 11 of the first moisture absorber 10 to the right side of the second moisture absorber 20. The temperature of the heater 90 is set to 120 ° C.

A blower (not shown) is provided on the right side of the second moisture absorber 20. This blower is located at a position where air on the right side of the second moisture absorber 20 can be sent to the left side of the first moisture absorber 10 from the other end surface (not shown) of the right end surface of the second moisture absorber 20 other than the fan-shaped end surface. Is set.
The air on the right side of the second moisture absorber 20 can be sent to the left side of the first moisture absorber 10 from the other end of the right end face of the second moisture absorber 20 other than the fan-shaped end face.

The gas exchange apparatus 100 according to the present embodiment having the above-described structure operates as follows.

The first moisture absorber 10 and the second moisture absorber 20 are rotated in opposite directions by a motor (not shown). In this case, the number of rotations per unit time of the first moisture absorber 10 and the second moisture absorber 20 is set to be the same.

The air on the right side of the second moisture absorbent 20 is blown by a blower (not shown) from the other end face (not shown) of the right end face of the second moisture absorbent 20 other than the fan-shaped end face.
It is introduced into the through-hole of the moisture absorbent 20 and is sent toward the left end face of the first moisture absorbent 10. In this case, the gas exchange device 1 of the present embodiment
00 indicates that the air introduced into the through hole of the second moisture absorbent 20
In the process of passing through the through holes of the moisture absorbent 20 and the first moisture absorbent 10, the carrier layer 6 containing zeolite powder as a moisture absorbent formed on the inner surface of the moisture contained in the air through the pores.
The air can be dehumidified by being adsorbed to zero.

In this way, the moisture contained in the air on the right side of the second moisture absorber 20 is reduced to the carrier layer 60 containing the zeolite powder.
Thus, the air on the right side of the second moisture absorber 20 can be supplied to the left side of the first moisture absorber 10 as dry air. In this case, since the removed moisture is adsorbed on the support layer 60 formed on the inner surface of the through hole through which the air has passed, the adsorption performance of the zeolite powder that has adsorbed the moisture is reduced accordingly.

On the other hand, the dried air on the left side of the first moisture absorber 10 is introduced into the through hole of the first moisture absorber 10 from the fan-shaped end face 11 of the left end face of the first moisture absorber 10 by a blower (not shown). Then, it is sent to the right side of the second moisture absorber 20. In this case, the dried air on the left side of the first moisture absorber 10 is heated by a heater 90 provided in front of the fan-shaped end surface 11 of the left end surface of the first moisture absorber 10 and introduced into the through hole of the fan-shaped end surface 11. Is done. As described above, in the gas exchange device 100 of the present embodiment, the dried and heated air introduced into the through hole of the fan-shaped end face 11 is heated by the first moisture absorber 10 and the second moisture absorber 20.
In the process of passing through the through hole, the support layer 60 containing the zeolite powder formed on the surface of the through hole is heated to dry the moisture adsorbed on the support layer 60 to regenerate the adsorption performance of the zeolite powder. be able to. The moisture adsorbed on the support layer 60 is absorbed by the heated air and can be discharged to the right of the second moisture absorber 20 as air containing moisture.

As described above, the first moisture absorber 10 and the second moisture absorber 10
The moisture absorber 20 is set to rotate in mutually opposite directions by a motor (not shown). Therefore, the dehumidification by the support layer 60 containing the zeolite powder formed inside the through holes of the first moisture absorber 10 and the second moisture absorber 20 and the regeneration of the adsorption performance can be alternately and continuously repeated.

Since the first moisture absorber 10 and the second moisture absorber 20 are set so as to rotate at the same period in the opposite directions to each other, the gas exchange device 100 of this embodiment uses a fan-shaped dry air. The portion where the through-holes are dried by passing through the end face 11 and the adsorption performance is regenerated moves in the clockwise direction of the fan-shaped end face 11 as viewed from the left side in the first moisture absorber 10 and the second moisture absorber 20 will move in the opposite direction. Therefore, the portion where the adsorption performance is regenerated moves to both sides of the fan-shaped end face. Therefore, in the gas exchange device of the present embodiment, the portion capable of exhibiting the moisture absorbing performance is so widened that the dehumidification can be performed efficiently.

(Comparative test) Gas exchange apparatus 1 of the above embodiment
In order to verify the moisture absorption performance of Example 00, a gas exchange device of a comparative example was prepared, and a comparison test with the gas exchange device of the example was performed.

The gas exchange apparatus of the comparative example has a width of 50 m.
Basically the same as the exchange device of the embodiment except that one disk-shaped moisture absorber having a diameter of 250 mm and a width (length in the axial direction) of 50 mm, which is constituted by a flat plate and a corrugated plate of m m, is used. It is. In the gas exchange device of the comparative example, the amount of the zeolite powder adhering to the moisture absorbent was 238 g.

Table 1 shows the conditions of the comparative test.

[0066]

[Table 1]

The adsorption side in Table 1 refers to a portion that adsorbs moisture. That is, it refers to a portion other than the fan-shaped end surface. Also, the regeneration side refers to a portion that regenerates the adsorption performance of the moisture absorbent. That is, it refers to the fan-shaped end face. The predetermined angle forming the fan-shaped end face is 90 degrees in this embodiment, and the area ratio between the suction-side end face and the reproduction-side end face is 3: 1. The same is set in the gas exchange device of the comparative example. The moisture absorber is set to make one rotation in 120 seconds. That is, in the embodiment, both the first moisture absorber and the second moisture absorber are set to make one rotation in the opposite direction in 120 seconds. In the comparative example, one moisture absorber is set to rotate in 120 seconds. Therefore, the time at which an arbitrary point stays on the regeneration side is 30 seconds in both the examples and the comparative examples, and the time at which any point stays on the adsorption side is 90 seconds.

The wind speed of the air sent from the fan-shaped end face and the wind speed of the air sent from the other end face other than the fan-shaped end face are both 2 m.
/ S. Furthermore, the humidity of the air sent to the adsorption side, that is, the air sent from the other end face other than the fan-shaped end face on the other end side has a humidity of 55%.
It is. That is, the humidity of the air sent to the suction side is 55%. And the temperature of this air is 40 ° C. The temperature of the air sent to the regeneration side is 120 ° C.

The dehumidifying performance was compared by measuring the amount of moisture dehumidified per hour by the gas exchange devices of the embodiment and the comparative example under such conditions.

FIG. 3 shows the result. The gas exchanger of the embodiment dehumidifies more than 800 g of water per hour, while the gas exchanger of the comparative example dehumidifies only more than 600 g of moisture per hour. I understand. From this, it can be clearly seen that the gas exchange device of the example has improved dehumidification performance. Therefore, when the entire length of the moisture absorber in the axial direction is equal, the gas exchange device that divides into two moisture absorbers and rotates them in opposite directions is more efficient than the gas exchange device that uses one moisture absorber. It can be seen that moisture can be absorbed and dehumidified.
