PPS+PTFE treated dust filter bag
In the field of bag filter, the dust bag is usually compared to the heart of the bag filter. The type of dusty flue gas that the bag filter can handle mainly depends on the conditions of the chemical fibers used to manufacture the bag. Under normal flue gas temperature conditions, only the dust removal filter bag needs to be able to withstand temperatures below 150 ℃. In these situations, chemical fibers such as polyester, polypropylene, acrylic, and nylon can be basically competent. For situations where the flue gas temperature is relatively high, such as chemical industry, carbon black (white carbon black) exhaust gas, blast furnace gas in ironworks, shaft kiln exhaust gas in cement plants, kiln exhaust gas in carbide plants, casting, steelmaking plant exhaust gas, asphalt concrete mixing asphalt exhaust gas, refractory brick kiln exhaust gas, coking flue gas, etc., firstly, because these dusty flue gas dust are not suitable for collection by electrostatic precipitators due to specific resistance limitations, and can only be collected by cloth bags or other methods; Secondly, if it is necessary to reduce the temperature of dusty flue gas to below 150 ℃, the investment may be high or limited by the site conditions; Thirdly, due to the presence of sulfur in dusty flue gas, it has an acid 'dew point' and can only be filtered and separated at temperatures above the acid dew point. Therefore, a chemical fiber high-temperature cloth bag that can withstand high temperatures is needed to make dust removal filter materials.
Practice has proven that PPS+PTFE needle punched felt can significantly improve the surface smoothness of high-temperature dust removal bags, making dust cleaning easier and reducing operating resistance. Therefore, the dust removal filter bag has no blockage phenomenon, and the filtration efficiency can reach 99.999%. Moreover, the combination of the two can greatly improve the service life, especially for high concentration and high humidity dust containing gases and high purification requirements. It has excellent performance in thermal power plants, carbon black plants, and steel plants with strict working conditions. Vibrating hammer
