High-efficiency rotary demister

Abstract

The invention discloses a high-efficiency rotary demister. The high-efficiency rotary demister comprises a plurality of demisting components; each demisting component comprises a gas riser pipe and anouter barrel; the outer barrel is arranged on the outer side of the gas riser pipe and located on the same axis as the gas riser pipe; the inner surface of the outer barrel is provided with spiral fins; the gas riser pipe is axially divided into an upper part and a lower part, the upper part is a gas riser pipe I, the lower part is a gas riser pipe II, the gas riser pipe I and the gas riser pipeII are connected with each other by a bearing, and the gas riser pipe II is fixed on a tray; and a rectifying passage is arranged on the circumference of the gas riser pipe I. The demister of the invention realizes the separation of droplets from gas by rectification, acceleration and scraping effect in the flowing process of fluids. The demister of the invention has the advantages of simple structure, convenient installation and small possibility of scale formation, and can effectively realize gas-liquid separation and reduce entrainment of mist.

Description

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

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.
