Description

[0001] The utility model relates to the field of chemical industry, in particular to a falling film absorption tower. Background Art

[0002] An absorption tower is a device used for gas absorption, usually used in the fields of chemical industry, environmental protection, etc. Its main function is to use liquid to form a thin film in the tower, absorb certain components in the gas into the liquid, thereby achieving gas purification or separation. A falling film absorption tower is a special absorption tower, and its working principle is to use liquid to form a thin film in the tower, absorb certain components in the gas into the liquid. The characteristics of this absorption tower are that the gas enters from below, the liquid enters from above, the liquid forms a thin film in the tower, and the gas passes through the thin film, thereby achieving gas absorption.

[0003] With the development of industry, the requirements for environmental protection are getting higher and higher. As a high-efficiency gas-liquid mass transfer equipment, the falling film absorber is widely used in chemical, environmental protection, pharmaceutical and other fields. The falling film absorber is prone to foam during operation, which will affect the gas absorption efficiency and the normal operation of the equipment, resulting in certain limitations of the falling film absorber, such as low absorption efficiency, high energy consumption, and complex operation. For this reason, we propose a falling film absorber to solve the above problems. Utility Model Content
