Abstract

The invention relates to a cooperative condensation wet-type electric dust precipitator and a working method thereof, and belongs to the field of industrial waste gas purification environment protection and energy. With comprehensive promotion of ultralow emission work of a coal-fired unit, a conventional pollutant index is effectively controlled, but how to solve control on fine particles and condensable particles becomes an essential issue in the current field of coal-fired smoke dust removal. According to the cooperative condensation wet-type electric dust precipitator, through organic combination of a wet-type electric dust precipitator and a smoke condensation device, particles in the smoke are firstly condensed and then charged, so that condensation of the condensable particles and agglomeration of the fine particles in the smoke are promoted; and the dust removing efficiency of the dust precipitator is promoted, and the cooperative removing capability of SO3 and other pollutantsis also improved. The cooperative condensation wet-type electric dust precipitator is simple in process, stable in operation, low in investment and operation cost and high in operability; the cooperative condensation wet-type electric dust precipitator has applicability to newly-built coal-fired units and improvement of current units; and therefore, the cooperative condensation wet-type electricdust precipitator has good environment-protection and economic benefits and wide application prospects.

Description

technical field [0001] The invention relates to a cooperative condensing wet electrostatic precipitator and a working method thereof, which belong to the field of industrial waste gas purification, environmental protection and energy. Background technique [0002] my country's coal-based energy structure will not change for a long time. Therefore, controlling the emission of particulate matter in coal-fired flue gas is an important task for my country's air pollution control. With the comprehensive advancement of the ultra-low emission work of coal-fired units, the conventional pollutant indicators have been effectively controlled, but how to effectively solve the control of fine particles and condensable particles has become an important issue in the field of coal-fired flue gas dust removal. [0003] Patents related to the present invention, such as CN 202398429 U——"A Method for Manufacturing a Wet Electrostatic Precipitator", that is, the currently conventionally used wet...
