Problems solved by technology

Therefore, when the humid air cooled by the heat exchanger is discharged to the outside of the shell B, the dehumidification efficiency is not high
Even if the humid air is not exhausted, but the humid air is sucked in by fan A, the humid air is mixed with the air near the casing B, so the dehumidification efficiency cannot be effectively improved.

Embodiment Construction

[0043] In the air dehumidification method of the present invention, the dehumidification element used is provided in the housing of the dehumidification device which will be described in detail later. At least one face of the dehumidification element has a water-absorbing material. The water-absorbing material can be any known water-absorbing material, and the water-absorbing material includes calcium chloride, lithium chloride, silica gel, molecular sieve and the like. Such water-absorbing materials can be coated or impregnated on the dehumidification element. Furthermore, all dehumidifying elements can be made of this water-absorbing material. The dehumidification element preferably has a number of passages therethrough. In this case, the channel inner wall surface has the above-mentioned water-absorbing material. Preferably, the diameter of the channel may be between 0.5-3 mm, but not limited to this range. Preferably, the dehumidification element can be in the shape of...

Abstract

Disclosed is a method and apparatus for dehumidifying air. The method comprises the steps of (I) contacting a dehumidification element which reversibily absorbs moisture in the air and which is contained in a housing of a dehumidification apparatus, with the air to be dehumidified; (II) discharging air to the outside of the housing, which air was dehumidified by the contact with the dehumidification element; (III) regenerating the dehumidification element by contacting the dehumidification element after absorbing the moisture in the air with heated air for regeneration of the dehumidification element so as to remove the moisture from the dehumidifica- tion element; (IV) reusing the dehumidification element in the setp (I) which was regenerated by the step (III); (V) cooling the air for regeneration of the dehumidification element after removing moisture from the dehumidification element in the step (III) so as to condense the moisture, and removing the generated water from the air for regeneration of the dehumidification element; and (VI) circulating the air for regeneration of the dehumidification element from the step (V) from which the water generated by condensation of moisture was removed, to the step (III); the air for regeneration of the dehumidification element is not substantially mixed with the air to be dehumidified or with the dehumidified air.

Description

technical field [0001] The invention relates to an air dehumidification method and device. Background technique [0002] German Patent Application Publication No. H8-155247 (Kokai) describes a conventional dehumidification device. [0003] Such as figure 1 and 2 As shown, the dehumidification device described in Patent Application Publication No. 6-324015 (Kokai) is used to send a part of the air to be dehumidified that has entered the device housing B through the fan A to the rotor rotatably provided in the housing B. C inside. After dehumidification by the rotor C, the dehumidified air is discharged to the outside of the case B. The other air that enters first flows through the channel F of the heat exchanger E, and then is sent to the dehumidification rotor C through the heater G, so that the dehumidification rotor C is regenerated. After that, the air that has become humid due to the regeneration of the dehumidification rotor C is sent to the channel H of the heat e...
