Abstract

The invention discloses a cross-flow type constant-temperature dehumidifying device. Two dehumidifying cores are adopted for alternately carrying out dehumidification and regeneration to obtain an uninterrupted dehumidifying effect. Adsorption heat is recycled, so that the problem that the performance of a dehumidifying agent is reduced due to the fact that the adsorption heat is accumulated in the dehumidifying cores and generates high temperature is avoided; and the adsorption heat generated in the dehumidification process is recovered by adopting air instead of liquid water, and the structure is simple, compact and light. The method for efficiently utilizing the low-grade waste heat is provided and accords with the strategic target of sustainable energy development, wherein the low-grade heat energy can be provided by solar energy, diesel flue gas waste heat, superheated steam exhaust steam and the like, and the application occasions of the adsorption type dehumidification technology are widened.

Description

technical field [0001] The invention relates to the technical field of dehumidification and energy saving, in particular to a cross-flow constant temperature dehumidification device. Background technique [0002] Air dehumidification units are widely used in food, pharmaceutical and other industries, as well as workshops, archives, museums, exhibition halls, laboratories and other places. At present, most dehumidification devices are mainly based on low-temperature condensation, and the system performance coefficient is not high. In contrast, another commonly used dehumidification method is solid adsorption dehumidification, which is in line with the development trend of industrial energy conservation and environmental protection in today's society. At present, the main device for solid adsorption is the dehumidification rotor, which has the advantages of simple structure, low noise, and long life. However, the treatment area of ​​the dehumidification rotor generates a larg...
