Abstract

The present invention relates to a double-vane air-swirl parallel-combination demister. The demister comprises one or more than two air-swirl demisting units and plugging plates, wherein a central axis of the air-swirl demisting unit is arranged in a vertical direction; and the air-swirl demisting unit comprises an outer barrel, a guide plate, an inner barrel, an outer guide vane, an inner guide vane, a sealing plate, a tapered section, an expanding section and a water drainage section. According to the demister disclosed by the invention, a working flow rate is increase and an ultimate grain size is reduced, so that the ultimate grain size of liquid drops captured by the demister is smaller than 15 microns, and therefore, effect of reducing the concentration of mist drops at an outlet of the demister is achieved, water loss is avoided, and secondary pollution to air is also avoided.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a flue gas demisting device at the outlet of an absorption tower in wet flue gas desulfurization technology and its application, in particular to a double-leaf aerodynamic swirling parallel combined demisting device and its application. Background technique [0002] Among flue gas desulfurization technologies, wet desulfurization technology is the most widely used. Its core equipment is the absorption tower, and the flue gas washed by the absorption tower will contain a large number of liquid droplets, which will be discharged with the flue gas. This not only causes the loss of a large amount of water, but at the same time, the dissolved and suspended particles in the water will also be discharged into the atmosphere together, causing secondary pollution of the air. [0003] In order to reduce the discharge of liquid droplets, the existing technical means is to in...
