Jiangsu YiNeng Environmental Protection Technology Co.,Ltd.as a high starting point, strong technical force of modern environmental protection science and technology entities, pay attention to "science and technology is the first productivity", and design units to cooperate with domestic and foreign research institutes, including the Ministry of science and technology has been the national 863 plan for PM2.5 electrostatic excitation type cloth bag dust remover. Is a kind of electrostatic excitation baghouse preparation method of filter material, including finishing and heat composite stainless steel fiber net plain felt preparation, after the law passed in the upper and lower sides of the symmetric fabric covered with non-woven layer, and through acupuncture and spunlace filter element into the mat, after finishing after heat composite filter surface covered with a layer of 0.01 0.1mm thick stainless steel net layer, resulting in electrostatic excitation baghouse filter material. The filter material prepared by the invention has the advantages of high temperature resistance, corrosion resistance, not only has the bag type dust collection dust, and closed as electrostatic precipitator of the collecting plate can greatly improve dust filtering efficiency and accuracy, reduce the filtration area, reduce the operation cost, are widely used in iron and steel smelting, waste incineration, coal-fired power plants, cement, chemical industry, etc. field of smoke and dust treatment.
