Dust collection polar plate based on particle trap effect, novel polarity form and efficient electrostatic dust collector

The invention relates to a dust collection polar plate based on a particle trap effect, a novel polarity form and an efficient electrostatic dust collector. The dust collection polar plate is bent toform a plurality of convex folded plates and grooves, particle traps are formed at the grooves, a novel polarity form of matching the dust collection polar plate with the multi-angle double-thorn electrode is low in dust accumulation thickness and high in field intensity at the convex parts of the particle traps, and particles at the convex parts easily enter the traps under the action of airflowdrag force or rapping. The thickness of accumulated dust in the grooves is large, but the field intensity in a formed dust layer is low, inter-particle breakdown and interference to discharge are prevented, the operating voltage working interval is increased, and the electrostatic dust collector is formed in cooperation with an intelligent rapping system. According to the invention, reentrainmentdust is reduced, the effective field intensity loss of high-specific-resistance fly ash is reduced, and the specific resistance application range and the working temperature window of the electric precipitator are widened. The dust collection polar plate has the advantages of improving corona current, strengthening fine particle charge, improving dust removal efficiency and the like, can reduce operation cost, and has high industrial applicability and operation reliability.
