Abstract

PURPOSE:To reduce the dehumidification cost of air by decompressing one part of dehumidified air discharged from one hand of chamber partitioned by a high molecular membrane to ordinary pressure and feeding this to the other chamber and combining pressurization apparatus of air with the apparatus wherein the air to be dehumidified is pressurized and thereby the partial pressure of steam incorporated in the air is increased. CONSTITUTION:The air a5 which is pressurized by a pressurization apparatus increasing the partial pressure of steam incorporated therein and cooled by a cooler and furthermore dust-removed is fed to one hand of chamber 8A of dehumidifier 5 partitioned by a high molecular membrane 8a selectively permeating steam. The steam incorporated in the dust-removed air a5 is transferred to the other chamber 8B through the membrane 8a by means of the partial pressure difference of steam between both chambers 8A, 8B and dehumidified. One part of the dehumidified air a6 is decompressed to ordinary pressure by a pressure reducing valve 9 and fed to the other chamber 8B via a feed path 10. The dehumidified air a6 discharged from the chamber 8A can be maintained in a pressurized state and the post pressurization thereof is unnecessary.

Therefore, the amount of water vapor partial pressure between both chambers can be increased, and dehumidification performance can be improved. Furthermore, when depressurizing a portion of the dehumidified air from one chamber to normal pressure and supplying it to the other chamber, all of the dehumidified air from one chamber is depressurized to normal pressure, and the dehumidified air that has been depressurized is Rather than supplying some to the other chamber,
A portion of the dehumidified air is taken out from one chamber, and the dehumidified air is depressurized and supplied to the other chamber. While adopting a form of dehumidification with superior dehumidification performance, such as supplying air to both chambers, most of the dehumidified air from one chamber can be maintained in a pressurized state. Therefore, the air to be dehumidified is supplied to one chamber at a pressure that takes into account the pressure drop caused by dehumidification in the water vapor permeation device, such as supplying to the other chamber, in addition to the pressure required depending on the application. By doing so, subsequent pressurization of the dehumidified air is not necessary.
