How is the filter bag chosen?
Second, if the protecting temperature degrees must be dropped to below 150 ℃ higher investment or restricted by the site; Three is due to gas containing dust because of containing sulphur ingredient, in protecting gas with acid "" dew point "protecting gas can only be in the form of acid dew point temperature is high above the filter elements such as separation, under so much demand have a chemical fiber can endure high temperature dust removal filter bag filter material used to make dust removal."
About high flue gas temperature compare, such as: chemical, carbon black (white carbon black), and iron blast furnace gas, cement kiln, and factory of calcium carbide kiln tail gas, forging, steel mills, asphalt concrete mixing asphalt smoke, refractory brick kiln gas, coking gas, etc., one is because of these gas containing dust dust because of restricted by resistivity is not suitable for electrical dust collector to collect, can only use dust filter bag or other methods to collect;
Ordinary on the premise of the flue gas temperature, dust removal filter bag can only demand resistance to below 150 ℃, the temperature of these places, polyester, polypropylene, acrylic, nylon and other chemical fiber can be competent at all.
