Description

Technical Field

[0001] This utility model relates to the field of solution dehumidification, and in particular to an energy-saving deep solution dehumidification device. Background Technology

[0002] Single-rotor dehumidifiers achieve continuous dehumidification circulation through the rotation of a rotor. The rotor is made of special ceramic fiber or silicone composite material, featuring a microporous structure, large surface area, and high moisture absorption efficiency. The equipment is divided into a treatment zone and a regeneration zone. Humid air is dehumidified in the treatment zone, and dry air is then introduced into the room. When the rotor rotates to the regeneration zone, high-temperature air restores its moisture absorption capacity, and the cycle repeats. However, single-rotor dehumidifiers suffer from high energy consumption, inefficiency, and environmental unfriendliness. Utility Model Content

[0059] The water tank 1023 is connected to the sprayer 1021 through a circulation pipeline, and a circulation pump is installed on the circulation pipeline;

[0067] In this embodiment, both the regeneration component 202 and the dehumidification component use a mixed salt solution of calcium chloride and lithium chloride, with a configuration ratio of 1:1 to 1:8. The mixed salt solution achieves efficient dehumidification, and the moisture content of the supplied air is kept stable at 1.3 g / Kg, avoiding the phenomenon that crystallization easily occurs in a single lithium chloride solution, which leads to unstable operation of the equipment.

[0068] Since the total air resistance of the dehumidification section is greater than that of the regeneration section, the first-stage dehumidification component in the dehumidification section of this application is designed to be under negative pressure and the second-stage dehumidification component is designed to be under positive pressure; the regeneration component 202 is designed to be under positive pressure. According to this design, the pressure difference between the three solutions can be reduced, the liquid level difference in the solution tank can be kept small during equipment operation, and the equipment can be guaranteed to operate stably.
