Description

Technical Field

[0001] This utility model relates to the field of dehumidification device technology, specifically to a dehumidification device for cleanrooms. Background Technology

[0002] A dehumidifier for cleanrooms is a device specifically designed for use in cleanroom environments. It reduces the humidity in the air to meet specific production processes or environmental requirements. The core principle is to reduce air humidity by condensing, adsorbing, or expelling moisture from the air through physical or chemical methods.

[0003] In existing technologies, solution-type dehumidifiers are generally used in cleanrooms. These dehumidifiers can introduce air into a chemical solution, and then use the chemical solution with hygroscopic properties (such as lithium chloride or lithium bromide solution) to absorb the moisture in the air. The dehumidified solution is then regenerated by heating and reused.

[0004] However, during the process of introducing air into the chemical solution, a large number of bubbles can be generated in the chemical solution. These bubbles will rise and return to the workshop environment due to buoyancy. This results in a low contact effect between the gas and the chemical solution, which in turn affects the dehumidification efficiency of the workshop. Utility Model Content
