The suction rotor 1 is driven to rotate in the direction of the arrow by a geared motor (not shown) or the like. The suction rotor 1 is divided into a suction zone 2, a regeneration zone 3, and a purge zone 4 in the rotation direction.

る。The indoor air is dried by the adsorption type dehumidifier in this manner. However, the dew point is -20 to -5 as in a lithium battery manufacturing plant.
When air having a very low dew point of 0 ° C. is required, the temperature of the heater 5 is set to a high temperature of 200 to 250 ° C.

いる。That is, from the adsorption principle of the adsorption type dehumidifier, the relative humidity of the air entering the regeneration zone 3 must be lower than that of the air exiting the adsorption zone 2. To lower the dew point of the air exiting the adsorption zone 2, By increasing the temperature of the air entering the regeneration zone 3, the relative humidity is reduced.

全のために断熱する必要があるという問題がある。For this reason, the temperature of the air exiting the regeneration zone 3 becomes as high as about 120 to 160 ° C., and a special heat-resistant blower 7 is required. Also, there is a problem that the duct for guiding the air that has exited the regeneration zone 3 is required to have heat resistance and needs to be insulated for safety.

For this reason, the indoor air is released to the outside by the amount of the regeneration air, and when the airtightness of the room is high, it is necessary to supply the outside air to the room. Therefore, the indoor humidity is affected by the outside air.

The air that has exited the regeneration zone of the first adsorption rotor is passed through the regeneration zone of the second adsorption rotor, and the high-temperature air that has exited the regeneration zone of the first adsorption rotor is the regeneration zone of the second adsorption rotor.

The ventilation area of the second suction rotor 12 is half of the ventilation area of the first suction rotor 8. The ventilation area ratio of the adsorption zone 9, the regeneration zone 10, and the purge zone 11 of the first adsorption rotor 8 is 2: 1: 1.
The ratio of the ventilation area of the adsorption zone 13 to the regeneration zone 14 of the second adsorption rotor 12 is 1: 1. Therefore, the ventilation area of the regeneration zone 10 of the first adsorption rotor 8 is equal to the ventilation area of the regeneration zone 14 of the second adsorption rotor 12.

で、冷却では結露を生じない。The adsorption type dehumidifier of the present invention is constructed as described above, and its operation will be described below by taking as an example a case where the device is used in a drying room having a minus dew point. First, room air is sucked in by the blower 16, and
Cooled at 7. Since indoor air has a dew point of 0 ° C. or less, condensation does not occur in cooling.

以下であった。The cooled room air is blown by the blower 16 into the adsorption zone 9 and the purge zone 1 of the first adsorption rotor 8.
Sent to 1. Since the room air is cooled and the relative humidity rises, it is effectively dehumidified in the adsorption zone 9 and returned to the room as dry air. Dew point is -40 ° C in applicant's experiment
It was below.

吸着ゾーン９での吸着を効果的にする。The air sent to the purge zone 11 exchanges heat with the first adsorption rotor 8, cools the first adsorption rotor 8, raises the temperature and returns the air to the inlet side of the cooler 17. . That is, the first adsorption rotor 8 is cooled to make the adsorption in the adsorption zone 9 effective.

る。On the other hand, the air passes through the adsorption zone 13 of the second adsorption rotor 12 by suction of the blower 18 and becomes dry air. When the dew point is 27 ° C. in a humid atmosphere in summer, the dew point of the air leaving the adsorption zone 13 is about 18 ° C. In addition, the temperature of the air exiting the adsorption zone 13 becomes about 120 ° C. due to the heat of adsorption and the heat brought in from the desorption zone 14.

, Where it is heated to 230 ° C. The high-temperature dry air enters the regeneration zone 10 of the first adsorption rotor 8, and desorbs moisture adsorbed by the first adsorption rotor 8.

この再生ゾーン１０を出た空気は相対湿度が外気より低
く、第２吸着ローター１２の脱着に使用かのうである。The temperature of the high-temperature dry air in the regeneration zone 10 is decreased by the heat of desorption, and the humidity is increased by the moisture desorbed from the adsorbent. That is, the temperature of the air leaving the regeneration zone 10 drops to 160 ° C., and the dew point rises to 32 ° C.
The air leaving the regeneration zone 10 has a lower relative humidity than the outside air, and can be used for desorption of the second adsorption rotor 12.

The air adsorbed by the second adsorption rotor 12 can be desorbed by passing through the air. The temperature of the air exiting the desorption zone 14 of the second adsorption rotor 12 drops to 83 ° C. and is released to the atmosphere.

装置は応用が容易である。As described above, the adsorption type dehumidifier of the present invention is constructed as described above, so that the temperature of the air exiting the desorption zone of the second adsorption rotor is low, and the regeneration is performed while providing the ability to supply air with an extremely low dew point. The temperature of the air leaving the zone can be lowered and the safety can be increased. Since the room air does not have to be used as the air flowing into the regeneration zone of the first adsorption rotor, the room air can be completely shut off from the outside air, and the adsorption type dehumidifier of the present invention can be applied to a clean room or a sterile room. Is easy.

を吸い出す配置が望ましい。Further, since the temperature of the air exiting the regeneration zone is low, it is easy to select a material such as a duct for sending the air and the price is low. Moreover, it is not necessary to use a blower having a high heat resistance for sucking out the air that has exited the regeneration zone.
In this regard, it is conceivable to dispose the blower so as to push the atmosphere into the regeneration zone. However, it is preferable to set the regeneration zone to a negative pressure so that the desorption effect is higher.

することができる。Further, since the adsorption-type dehumidifying apparatus of the present invention has a structure in which the first adsorption rotor is desorbed by the dry air generated by the second adsorption rotor, the first humidity is determined by the relative humidity of the air entering the adsorption zone of the first adsorption rotor. The relative humidity of air entering the regeneration zone of the adsorption rotor can be easily reduced,
The dew point of the air exiting the adsorption zone of the first adsorption rotor can be reduced.

ーターが冷却され、吸着効果が高い。また第１吸着吸ロ

たことも吸着効果を高める。Since a purge zone is provided in the first adsorption / suction rotor and the air that has exited the purge zone is returned to the adsorption zone, the first adsorption / suction rotor is cooled before entering the adsorption zone, and the adsorption effect is reduced. high. In addition, cooling the air before entering the adsorption zone of the first adsorption / suction rotor also enhances the adsorption effect.

い。Since the ventilation areas of the regeneration zone of the first adsorption and absorption rotor and the regeneration zone of the second adsorption rotor were made equal,
Since the flow velocity of the air flow passing through both zones is equal, the increase in air resistance is not so large even after passing through the two zones.
