Acrylic filter bags-special for sintering machine gas dust collector
Acrylic dust filter bag has good resistance to organic solvents, oxidants, inorganic acids and organic acids when used at 130 C, is good selection for sintering machine gas dust collector.
A lot of dusty smoke comes out of sintering machine in the process of production, and there are many fine particles of dust smaller than 10 micron in the flue gas. The dust temperature is 130 to 150 degrees under normal conditions, and the dew point temperature of the sintering machine can reach 80 degrees centigrade. This is a difficult problem of using bag filter. But it is proved that the safe operation of bag type dust collector can be ensured by keeping the operating temperature of the bag filter above the dew point temperature above 15~20 degrees C, and adopting the measures of holding the bag type dust collector to keep the heat. The maximum temperature of the flue gas of the sintering machine can reach 200 c. In the past, the lack of high temperature dust collector bag filter material has become an obstacle to the application of bag type dust collector, but there are several kinds of high temperature dusting bag filter material and flue gas cooling device, and the high temperature smoke can not cause any threat to the bag type dust remover. Sintering head flue gas contains SOx and other acidic substances, but compared with other industries, the content of corrosive gas bag filter is much lower than that of other industries. To sum up, if we want to control dust laden flue gas from sintering machine, we must select high temperature resistant and acid resistant filter bag filter cloth.
Acrylic acid and alkali resistant filter bag fiber is a non-thermoplastic fiber.
Acrylic dust filter bag has good resistance to organic solvents, oxidants, inorganic acids and organic acids when used at 130 C.
Acrylic filter bag is not easy to hydrrolyze.
Acrylic filter bag has good heat resistance and corrosion resistance under dry and wet conditions.
Acrylic filter bag can maintain stable performance in hot and sour conditions.
Under the condition of dry and hot working, acrylic fiber filter bag has better performance than natural fiber. Acrylic bag filter material has strong resistance to most inorganic acids and organic acids. Acrylic bag filter material can replace polyester in low temperature and chemical corrosion and wet environment.
For the filter material of acrylic filter bag, the higher the acid gas concentration is, the larger the longitudinal shrinkage of the filter bag filter material is, the shrinkage amplitude of the acrylic filter bag is at the maximum when the acid gas concentration reaches a certain value, and the transverse size shrinkage of the bag is not affected. That is to say, the lateral size of acrylic filter bag can still maintain excellent size under different acid conditions.
But it is worth noting that the filter material of the acrylic filter bag can not be used in the alkaline condition environment. With the increase of the alkaline gas concentration, the performance of the acrylic filter bag will be affected by different degrees. The physical properties of the bag can be greatly damaged, and the dust bag completely loses its utility when the concentration of basic gas reaches a certain value.
After different surface treatment processes, acrylic dust removal filter bags also have the characteristics of water resistance, oil resistance, acid and alkali resistance, oxidation resistance and so on.
Acrylic felt filter bags are widely used not only in the field of sintering machine dust removal, but also widely used in iron and steel, slag and chemical industry. Acrylic filter bag can effectively filter out the fine particles in the smoke and reduce the air pollution caused by fine particles such as PM2.5.
