Abstract

The invention relates to a pneumatic-cyclone parallel-combination demister and application thereof. The demister comprises one or more than two pneumatic-cyclone demisting units and a closing plate, wherein the central axis of each pneumatic-cyclone demisting unit is arranged in the vertical direction, and each pneumatic-cyclone demisting unit comprises a tubular body, a flow guide vane, a sealing plate, flow guiding plates, a tapering section, an expanding section and a drainage section. According to the demister, the one or more than two pneumatic-cyclone demisting units and the closing plate are arranged, so that the working flow rate is increased, and the limit particle size is lowered; and the limit particle size of liquid droplets captured by the demister can be smaller than 15 microns, so that the effect of lowering the concentration of fog droplets of an outlet of the demister is achieved, the loss of water is avoided, and meanwhile, the secondary pollution to air is 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 pneumatic cyclone 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 air pollution. [0003] In order to reduce the discharge of liquid droplets, the existing technical means is to install a mist eliminato...
