Cyclone separation water absorbing device used for flue gas dehydration

Abstract

The invention belongs to the technical field of wet method desulfurized tail gas dehydration, and provides a cyclone separation water absorbing device used for flue gas dehydration. On the basis of anoriginal flue gas dehydration device, cyclone separation water absorbing filling is additionally arranged, is of a hollowed cone frustum structure with a variable diameter, and is fixedly installed in a flue gas dehydrating device body and located on a cyclone separation blade; from a flue gas inlet end to a flue gas outlet end, the diameter of the cyclone separation water absorbing filling gradually becomes smaller; the angle formed by the section of the cyclone separation water absorbing filling and a horizontal plane is determined by the angle where flue gas comes out of the cyclone separation blade, and in other words, the flue gas which comes out of the cyclone separation blade perpendicularly makes contact with the cyclone separation water absorbing filling. In actual work, the water absorbing efficiency of media can be effectively improved, the actual proportion of flue gas with water removal can be increased, and after the media absorb water, secondary carrying of gas can be avoided.

Description

technical field [0001] The invention belongs to the technical field of wet desulfurization tail gas dehydration, in particular to a cyclone water absorption device for flue gas dehydration. Background technique [0002] SO in factory flue gas 2 The emission of sulphur is one of the main causes of air pollution, and the use of wet desulfurization technology is a common technology. However, the moisture content (gaseous and liquid) of the exhaust gas through wet desulfurization technology is as high as 20%, and the flue gas will gather into droplets on the flue pipe wall, which will cause rain, and cause corrosion to the pipe wall and even the fan, resulting in the wet desulfurization system. Outages may even lead to the shutdown of the entire unit. The commonly used solution for flue gas dehydration is corrugated plate mist eliminator, which can achieve 50% efficiency in separating and recovering liquid water. The principle of dehydration in the flue is that the fine dropl...
