Straight cylinder-shaped flow baffling type demister

Abstract

The present invention discloses a straight cylinder-shaped flow baffling type demister, which comprises a plurality of demisting assemblies, wherein each demisting assembly comprises a gas rising pipe and a straight cylinder, the straight cylinder is arranged on the outer side of the gas rising pipe and is at the same axis line as the gas rising pipe, the gas rising pipe is fixed on a tower disk, the top portion of the gas rising pipe is provided with a sealing cover plate, the circumference of the gas rising pipe is provided with a plurality of seams, and the gas rising pipe circumference close to each seam is provided with tangential diversion wings. According to the straight cylinder-shaped flow baffling type demister, the separation of the liquid droplet and the gas is achieved through the multiple flow baffling during the fluid flowing process; and the straight cylinder-shaped flow baffling type demister has characteristics of simple structure, easy installation and effective gas-liquid separation achieving, and is suitable for the gas-liquid separation process in the fields of chemical industry, environmental protection, and the like.

Description

technical field [0001] The invention relates to a straight cylindrical baffle type demister, which belongs to the field of gas-liquid separation in chemical engineering and is suitable for the gas-liquid separation process in the fields of chemical engineering, environmental protection and the like. Background technique [0002] SO 2 And dust is an important cause of air pollution in my country, and it is also an air pollutant that is currently under control in our country. At present, wet process is mostly used in the field of environmental protection. In the process of wet process flue gas desulfurization, the absorption tower is easy to generate "fog" with a particle size of 10-60 microns during operation, which not only contains water, but also dissolves sulfuric acid. , sulfate, SO 2 etc., causing pollution to the atmospheric environment, and at the same time causing serious corrosion to the exhaust pipe and heat exchanger. Therefore, in the wet desulfurization proce...

Problems solved by technology

In the process of separating the liquid phase from the gas phase in this technology, gas-liquid cross-flow can be realized, so the secondary entrainment effect of the gas relative to the liquid droplets 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.
