Electric mote remover

Abstract

The invention provides an electric mote remover, comprising a coagulation area, a diversion area and a film type static dust-removing area which are communicated in sequence. The coagulation area is conducted with a normal electric dust-removing system; a plurality of dust collecting boards are arranged at intervals, so as to form a plurality of mote channels the direction of which are consistent with the mote direction; discharging electrodes which are vertical to the mote direction and are the same in polarity are arranged in the same mote channel; the polarities of discharging electrodes in the adjacent mote channels are reverse, so that motes passing through the area carry different charges; the diversion area is communicated with the coagulation area; a plurality of diversion plates which are vertical with the mote direction are arranged; the side faces of the diversion plates face to the mote direction, so that the motes with the different charges are coagulated in the area; the film type static dust-removing area is communicated with the diversion area and is provided with a plurality of dust collecting films at intervals, so as to form a plurality of charge mote channels in a direction consistent to the mote direction; and a plurality of cathode discharging electrodes are arranged in each charge mote channel, so that the coagulated charge motes are captured by the dust collecting films. The electric mote remover provided by the invention has the advantages of optimal effect and low cost.

Description

technical field [0001] The invention relates to dust removal technology in the thermal power industry, in particular to a fine dust electrostatic precipitator. Background technique [0002] PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 μm in the atmosphere, also known as particulate matter that can enter the lungs. Although it is only a small component in the earth's atmospheric composition, it has an important impact on air quality and visibility. Compared with coarser atmospheric particles, PM2.5 has a small particle size, is rich in a large amount of toxic and harmful substances, and has a long residence time in the atmosphere and a long transportation distance, so it has a greater impact on human health and atmospheric environment quality . [0003] From 2000 to 2007, my country's annual industrial dust emissions exceeded 8 million tons (about 4 million tons in the thermal power industry), including about 4 million tons of fine particles ...
