Since the explosive used in the case of explosive dust so the operation of such dust on the filter is different from the ordinary, here we introduce in the operation should be explosion-proof bag filter attention to what matters. ① explosion-proof bag filter running, do not open Manhole, cover, poke holes and other materials, if there are explosion-proof dust smoldering fire phenomenon nausea, gas will enter the wall from dust explosion at the holes, causing deflagration and explosion. Process equipment stops running, workers have to be checked when entering the inner dust explosion, explosion-proof should be careful not to blast cooling bag filter, bag filter valve should be closed on the inlet and outlet piping, allowed to cool naturally. ② explosion in the open air baghouse, should be rain measures to prevent rainwater from entering the insulation, the insulation effect and reduce adverse consequences condensed, or clogged dust bag. ③ to the explosion-proof type bag filter blowing inert gas fire, the import and export pipeline valve should be closed, otherwise inert gas will soon be the dilution air, fire would not achieve results. ④ avoid external radiation source, such as from combustion devices should be a certain distance, or additions shrouds. ⑤ dust before stopping to have enough idle time to completely remove dust and conveying system of pulverized coal and other easily combustible dust.
