Abstract

The invention discloses a high-efficiency coupling dust collector and a dust removal method suitable for desulfurization and dust removal absorption towers. The high-efficiency coupling dust collector includes an impact dust removal area, which includes two or more rows of circular tube layers arranged in parallel up and down, and is relatively Two adjacent rows of round tube layers are arranged alternately; the electric field dust removal area includes an anode plate for dust collection and a cathode line for discharge; a flushing spray layer is arranged above the electric field dust removal area; Wherein, the flue gas flows sequentially through the impact dust removal area, the electric field dust removal area and the flushing spray layer. The dedusting method includes: impacting the flue gas to be treated flowing in from the flue gas inlet; performing electric field force adsorption treatment on the impacted flue gas; intermittently or continuously spraying and cleaning the anode plate and the cathode line. The invention can effectively ensure the high-efficiency and stable operation of the dust collector, can improve the removal efficiency of fine particles in flue gas, and meet the requirement of ultra-clean discharge of particles.

Description

technical field [0001] The invention belongs to the technical field of air pollution prevention and control, in particular to a high-efficiency coupling dust collector and a dust removal method suitable for a desulfurization dust removal absorption tower. Background technique [0002] Following the release of the "Notice on Issues Concerning the Implementation of Ultra-Low Emission Power Price Support Policies for Coal-fired Power Plants" in early December 2015, the Ministry of Environmental Protection, the National Development and Reform Commission, and the Energy Bureau issued the "Comprehensive Implementation of Ultra-Low Emission and Energy-Saving Transformation Work Plans for Coal-fired Power Plants" in the same month. ", to clarify the timetable for ultra-low emissions. The comprehensive implementation of ultra-low emission and energy-saving transformation of coal-fired power plants is an important measure to promote the clean utilization of coal, improve the quality o...
