The filter bag of the precipitator is called the heart of the precipitator when it is in use. When the filter bag is used, the selection of the filter bag is very important. When it is used, it will directly affect the dust-removing effect of the equipment, the gas temperature and the humidity of the equipment. And chemical properties; particle size; dust concentration; filtration wind speed;
The burning and pressing treatment of the filter bag of the precipitator will be effective in the use of advanced singeing, calendering, and needle-punching filter material after the tentering and shaping treatment, and the single-sided and double-sided The use of the process has the unparalleled advantages of ordinary singeing and calendering, both in the use of the filter to improve the cleaning performance, but also to meet the collection of fine dust.
Some dust of the filter bag in the state of a certain concentration, in the use of the spark will occur when it is burning, so when used in the flammable and explosive dust should be selected by the anti-static (anti-static) treatment Needle felt filter. Anti-static (anti-static) filter material refers to the mixture of conductive fibers in the filter fiber (including binary conductive fibers, graphite wire conductive fibers and stainless steel conductive fibers), the entire filter material has conductive properties.
The filter bag of the dust collector effectively uses the fluorocarbon resin and the PTFE impregnated oil-proof and waterproof treatment for the thorn felt filter material, especially for the surface of the wet dust-containing gas filter bag, so as to prevent dust from collapsing and to reduce the occurrence of the paste bag phenomenon. .
The filter bag of the dust collector effectively adopts the patented technology to produce the easy-cleaning needle punch felt. The filter material itself is dense and breathable, and has good dust-cleaning performance, and can work for a long time under a high filtration wind speed. When the particle size of the dust is less than 1 micron, or when the dust is very viscous, or the gas contains high humidity, ordinary filter media cannot be effectively filtered. The coated film material made of PTFE (Teflon) has extremely high filtration accuracy, a smooth surface, and does not adhere to dust. It is easy for the dust-free dust to penetrate into the filter media and achieve surface filtration.
