Application and research progress of deep dehumidification technology in low-humidity industry

Humidity control is of great significance to industrial production. In the industries of lithium battery, pharmaceutical, food and others, low-humidity environment is an important guarantee for the effective development of the industry. Firstly, the dehumidification demands of related low-humidity industries are investigated in this paper. Secondly, the commonly used deep dehumidification technologies to ensure the requirements of low-humidity environments are reviewed, including refrigeration dehumidification, liquid absorption dehumidification, solid adsorption dehumidification, membrane dehumidification, and multi-technology joint dehumidification, and a matching analysis of the low-humidity environment demand and dehumidification technology is conducted. Then, the latest research progress of common deep dehumidification technologies and some new dehumidification technologies are presented, such as electrolyte membrane dehumidification and electrodialysis dehumidification. Finally, the application and research of deep dehumidification technologies are summarized and prospected.
