Efficient demister

Abstract

The invention discloses an efficient demister. The demister comprises a plurality of demisting assemblies, wherein each demisting assembly comprises a riser and an outer cylinder, the outer cylinder is arranged on the outer side of the riser and located in the same axis with the riser, the riser is axially divided into an upper part and a lower part, the upper part is a riser I, the lower part isa riser II, the riser I and the riser II are connected through a bearing, the riser II is fixed on a tray, and rectifying channels are arranged on the circumference of the riser I. The demister can realize separation of drops from gas through rectification, acceleration and scraping effects of a fluid during flowing. The demister is simple in structure, convenient to mount, not prone to scaling and capable of effectively realizing gas-liquid separation and reducing entrainment.

Description

technical field [0001] The invention relates to a gas-liquid separation device, in particular to a high-efficiency demister. 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 ...

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.
