How to solve the running resistance of the pulse bag filter is high?

(1) cleaning time is short, the cleaning cycle is too long, the dust on the bag could not be cleaned, the dust on the filter into the state, will make the running resistance soon increased. For pulse jet bag filter, the cleaning process takes time (ie, pulse valve injection time) for the cleaning time, adjustable in the range of 0.05 ~ 0.5s. Two cleaning interval of time for the cleaning cycle is generally 0 ~ 30min. Adjustment pulse bag filter cleaning system, appropriate to extend the cleaning time, increasing the amount of compressed air and induced gas injected into bag inside; while reducing the cleaning cycle even continuous cleaning mode, it can make more cleaning bag to completely and effectively reduce the running resistance. (2) when the pulse bag filter processing temperature, high humidity gas, if you run the gas temperature below the dew point, the water vapor will condensate condensation, damp of the bag, a lot of dust adhered to the surface of the bag, the bag clogging porosity, and blowing compressed air can not be cleared, causing the bag paste bag. Produce the paste bag filter cleaning function fails, the resistance is too large, the deterioration of health. To prevent the pulse bag dust condensation paste bag, it must maintain the process gas temperature above the dew point 25 ~ 35 ℃. The filter used to process high temperature, high humidity gas, temperature detection alarm device should be installed at the entrance to monitor the installation of rock wool and other insulation materials insulation in housing. Dust removal system before stopping the run, you must be within the wet gas precipitator completely discharged and put on dry air to prevent condensation, which is stopped in the production of equipment, dust blower should be extended to run for some time after shutdown. (3) pulse jet bag filter typically operates under negative pressure, if the equipment leaks, breathe the outside air and a lot of rain, so the bag damp compaction, increase the running resistance. Thus requiring the precipitator strict sealing, air leakage rate of less than 3%. In the installation process, the welding quality is essential. All welds must be in accordance with the appropriate specifications, standards implementation, after the welding is completed kerosene, phosphor leak check, etc., must be re-weld leak place. Precipitator inspection door must be rubber seal, and regularly check and replace. Carefully check the unloader and the flange, good seal. Reduce the amount of dust collector leak, can effectively protect the bag to avoid the occurrence of paste bag, to ensure the smooth operation of equipment at lower resistance. (4) pulse jet bag filter generally use compressed air injection cleaning, compressed air contains more oil, water, impurities, if not purified directly injected into the bag, it will make the bag contaminated damp cause junction dew. If the filter processing is a high temperature, high humidity gas, once injected into the cold compressed air, such as hot and cold intersection to reach the dew point temperature will cause condensation in the bag surface adhesion lot of dust caused by compaction after. To avoid air impurities cause compaction paste bag, it must develop and implement work system, adhere to open the gas tank every day, triple gas source, pulse valve points the air bag drain valve to exclude oil and water contaminants. And before the pulse valve sub air bag installation freeze dryer and heater, compressed air dehydration and heat up further and then be injected into the bag cleaning.
