Absorption tower

Abstract

The invention relates to absorption towers, in particular to an activated carbon adsorption tower which is provided with heat-exchange tubes and is used for exhaust gas adsorption. A jacket is additionally arranged outside the absorption tower provided by the invention; heat-exchange tube groups are additionally arranged inside the absorption tower; the heat-exchange tube groups are in welded connection with a lower sealing head; the heat-exchange tube groups consist of heat-exchange tubes; the heat-exchange tubes are double-layer structures consisting of inner sleeves and outer sleeves; axial fins are arranged on the inner sleeves; liquid inlets of the heat-exchange tube groups are communicated with the outer sleeves of the heat-exchange tubes; liquid outlets of the heat-exchange tube groups are communicated with the inner sleeves of the heat-exchange tubes; the connection manner among the heat-exchange tubes is that an outer sleeve of one heat-exchange tube is communicated with an inner sleeve of another heat-exchange tube. The absorption tower provided by the invention has high heat-exchange efficiency and a good absorption effect; the space inside the absorption tower can be sufficiently utilized; the volume of the absorption tower is reduced to the maximum; and the requirements of sites for mounting the absorption tower are lowered. The absorption tower provided by the invention can be applied to the production fields, such as polysilicon, fine chemicals or pharmaceuticals.

Description

technical field [0001] The invention relates to an adsorption tower, in particular to an activated carbon adsorption tower provided with a heat exchange tube group. Background technique [0002] The activated carbon adsorption tower can absorb and recover the exhaust gas of organic solvents such as benzene, alcohol, ketone, benzene, ester, gasoline, etc., and is more suitable for the treatment of exhaust gas with small air volume and high concentration. , electronics, leather industry, latex products industry, papermaking and other industries can be used. Activated carbon adsorption equipment mainly uses porous solid adsorbent activated carbon to have adsorption effect, which can effectively remove organic pollutants and color and smell in industrial waste gas. It is widely used in the terminal treatment of industrial organic waste gas purification, and the purification effect is good. After the gas enters the absorption tower through the pipeline, a diffusion process occur...
