Solid adsorbent (such as silica gel, in the sub-screen, active gasification aluminum, zeolite, etc.) as a fixed bed, Filling in the chemical dehumidifier tower (cylinder), the use of two towers above the tower, Adsorption of a tower for the air and water regeneration another tower, After a certain period of time will change and alter tower loop so that air and moisture regeneration swap This will have intermittent air dehumidification.

Chemical dehumidifier adsorbent surface of the porous structure, dehumidifiers.com.cn/News/HumidityConcept/" target="_blank">Moisture in the air due to adsorption and capillary effect on the surface, it is hygroscopic role. (Figure 2)

(Characteristics)

(1) the use of chemical dehumidifier solid adsorbent available to low dew point desiccant air.

(2) chemical dehumidifier to a fixed time for a change desiccant regeneration, it is not stable for the desiccant air.

(3) chemical dehumidifier require regular replacement of adsorbents.

(4) chemical dehumidifier device big pressure loss.

(5) chemical dehumidifier regeneration temperature high.

(6) chemical dehumidifier gas flows for the entire loop closed. it can be used for non-air gas dehumidification.
