Demisting equipment

Abstract

The invention discloses demisting equipment. The demisting equipment comprises several parallel demisting components, each demisting component comprises a gas rising pipe and an outer cylinder, and the outer cylinder is arranged outside the gas rising pipe; the gas rising pipe is divided into an upper part and a lower part along an axial direction, the upper part is an gas rising pipe I, the lowerpart is a gas rising pipe II, and the gas rising pipe I and the gas rising pipe II are connected through a bearing; rectification channels are uniformly arranged on circumference of the gas rising pipe I; the gas rising pipe II is fixedly arranged at a tower disk, the bottom of the gas rising pipe II is lower than the tower disk with a certain distance, several air inlets are uniformly arranged at the circumference of a part of the gas rising pipe II below the tower disk, and several air-inlet flow deflectors are arranged on an inner wall of the gas rising pipe II at the air inlet. The demisting equipment realizes separation of liquid drops and gas through rectification, acceleration and scudding effects during a fluid flowing process. The demisting equipment has the advantages of simplestructure, low pressure drop, difficult fouling, and convenient installation, and reduces mist entrainment, and effectively realizes gas-liquid separation.

Description

technical field [0001] The invention relates to a gas-liquid separation device, in particular to a demisting device. Background technique [0002] A large amount of SO is produced in the production process of electric power, metallurgy, petrochemical and other industries 2 Harmful substances such as dust and dust have brought serious acid rain hazards and smog weather, and are currently the key air pollutants controlled in our country. At present, the wet desulfurization process is widely used in the field of environmental protection to remove sulfur dioxide and other harmful substances in the flue gas, that is, to 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 fine droplets with a particle size of about 10-60 microns, and sulfuric acid, sulfate, SO 2 etc., will not only pollute the atmospheric environment, but also cau...

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.
