How to choose material for filter bag of dust collector?
two is for the dust temperature is below 150 DEG C or higher investment by site restrictions; three is due to the presence of sulfur components due to dust, dust has "acid dew point" "dust only at higher temperature is above the dew point form filtering separation and other factors, it needs a chemical fiber filter can withstand higher temperatures for To make dedusting filter material. "
And on the flue gas temperature is relatively high places, such as chemical industry, carbon black (silica) exhaust, BF gas, shaft kiln cement plant exhaust, calcium carbide plant, steel plant, forging furnace exhaust gas, asphalt mixing asphalt and refractory brick kiln flue gas furnace flue gas, coking gas smoke, one is because of these dust due to dust specific resistance limit is not suitable for electric dust collection, can only use the dust bag or other methods;
The temperature of flue gas under the premise of ordinary, only dust bag can be resistant to a temperature below 150 DEG C, these places, polyester, polypropylene, acrylic, nylon and other chemical fiber can be competent.
