The invention discloses a high-efficiency coupling dust remover applicable to a desulfurization dust-removing absorption tower and a dust removing method thereof. The high-efficiency coupling dust remover comprises an impact dust-removing area, an electric-field dust-removing area and a washing and spraying layer, wherein the impact dust-removing area comprises two or more rows of round pipe layers which are arranged in parallel from top to bottom, and each two adjacent upper and lower rows of round pipe layers are arranged in a staggering manner; the electric-field dust-removing area comprises an anode plate for collecting dust and a cathode line for discharging; the washing and spraying layer is arranged above the electric-field dust-removing area; flue gas flows through the impact dust-removing area, the electric-field dust-removing area and the washing and spraying layer in sequence. The dust removing method comprises the following steps: carrying out impact treatment on flue gas to be treated entering from a flue-gas inlet; carrying out electric-field force adsorption treatment on the flue gas after impact treatment; and carrying out intermittent or continuous spraying cleaning on the anode plate and the cathode line. The high-efficiency coupling dust remover disclosed by the invention has the advantages that high-efficiency and stable operation of the dust remover can be effectively guaranteed, the efficiency of removing fine particles in the flue gas can be improved and thus the requirement on ultraclean emission of particles is met.
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...
