A high-efficiency defogging device

Abstract

The invention discloses efficient demisting equipment. The demisting equipment comprises a plurality of demisting assemblies, wherein each demisting assembly comprises a gas lift tube and an outer cylinder, the outer cylinder is arranged on the outer side of the gas lift tube and located in the same axis with the gas lift tube, the gas lift tube is fixed on a column tray, an upper seal cover plateis arranged at the top of the gas lift tube, a lower seal cover plate is arranged at the bottom of the gas lift tube, gas inlet holes are uniformly formed in the circumference of the lower end of thegas lift tube, gas inlet guide plates are arranged in the positions, located at the gas inlet holes, of the inner wall of the gas lift tube, and rectification channels are formed in the circumferenceof the upper end of the gas lift tube. According to the demisting equipment, separation of liquid drops and gas is realized under the rectification, acceleration and scudding effects of fluid in theflowing process. The demisting equipment is simple in structure and convenient to mount, is not prone to scaling, can realize gas-liquid separation effectively and reduce entrainment, and is particularly suitable for occasions with higher gas flow fluctuation.

Description

Technical field [0001] The invention relates to a gas-liquid separation device, in particular to a high-efficiency defogging device. Background technique [0002] A large amount of SO is generated in the production process of electric power, metallurgy, petrochemical and other industries 2 Hazardous substances such as dust and dust have caused serious acid rain hazards and haze weather. They are currently the air pollutants that my country is currently focusing on controlling. At present, in the field of environmental protection, a wet desulfurization process is generally used to remove harmful substances such as sulfur dioxide in the flue gas, that is, spray lye on the flue gas to absorb or adsorb these harmful substances. However, in the wet desulfurization process, the flue gas after desulfurization in the absorption tower contains a large number of small droplets with a particle size of about 10-60 microns. These droplets contain sulfuric acid, sulfate, and SO. 2 It will not ...

AI Technical Summary

Problems solved by technology

During the separation process of the liquid phase and the gas phase of this technology, gas-liquid cross flow can be realized, so the secondary entrainment effect of the gas relative to the liquid droplet is greatly reduced, but the technical structure is very complicated, the processing difficulty is relatively large, and the corresponding processing and production costs are relatively high.
