Electret material and electrostatic dust collection device

Abstract

The invention provides an electret material and an electrostatic dust collection device. The electret material is formed by mixing polystyrene and polytetrafluoroethylene/polyvinylidene difluoride asraw materials, wherein the grain size of the polytetrafluoroethylene/polyvinylidene difluoride is 1-10 microns. Through an improvement on the electret material, the filtration performance of an electrostatic precipitation filter of a microchannel structure made of the electret material is improved. The electrostatic dust collection device reduces the probability of occurrence of the polarization phenomenon by detecting the environmental particulate matter concentration, designing the structural style of a charged component, controlling emission current, releasing and reestablishing an internalelectric field and reducing the convergence of an internal surface electric field of dust collection microchannels, and then the dust capacity and dust collection efficiency of the electrostatic precipitation filter of the microchannel structure made of the electret material are improved. The cleaning and maintenance period is prolonged while the dust capacity is improved, and the use and maintenance cost is lowered.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to an electret material and an electrostatic dust removal device. Background technique [0002] The traditional electrostatic dust accumulation filter uses a metal parallel plate structure as the dust accumulation part and a corona wire as the charging part. It has a history of nearly 60 years and is widely used in the field of industrial dust removal and ventilation equipment dust accumulation. Due to the ignition of the discharge point between the electrodes, the high concentration of corona ozone, and the safety problems of exposed high-voltage parts, the application of indoor air purification products is limited. [0003] The electrostatic dust accumulation filter with micro-channel structure made of electret material has the characteristics of high dust accumulation efficiency, large dust holding capacity, and can be cleaned and reused, and has been more and more widely us...
