DEHUMIDIFYING UNIT, LAYERED TEMPERATURE CONTROL DEHUMIDIFYING ELEMENT AND DRYING DEVICE

摘要

A dehumidifying unit, a layered temperature control dehumidifying element and a drying device are provided. The dehumidifying element has a plurality of dehumidifying units. The dehumidifying units are made of a direct heating desorption material and used for dehumidifying air by adsorption and capable of being regenerated by desorption. By performing temperature compensation through a preheater and performing a layered temperature control method on the dehumidifying element, the disclosure achieves a uniform temperature control on the air flow passage of the dehumidifying element so as to improve regeneration performance of the dehumidifying element and reduce energy consumption of the drying device.

主权项

1. A dehumidifying unit, comprising:
an upper frame and a lower frame each having a plurality of rib portions, wherein a gap is formed between any adjacent two of the rib portions; a plurality of upper screw bolts and lower screw bolts fixed to the upper frame and the lower frame respectively; a direct heating desorption material wound around the rib portions of the upper frame and the lower frame alternately to form a passage therebetween, wherein the direct heating desorption material has a metal sheet therein between two desorption sides of the direct heating desorption material; and two conductive plates conductively connected to portions of the metal sheet exposed from the two desorption sides of the direct heating desorption material and fixed to the upper frame to form two electrodes.
