Works produced by the induced draft fan working in the bag and external pressure, so that the outside of the particulate dust bag henchmen, led by the fan clean air, including dust, gas provided by one or both of the air intake, the use of pulse cleaning bag type dust blowing system, because pulse controller and electromagnetic valve. Intermittent injection for the filter to continuously remove dust bag attached to the surface. It outputs a control signal electromagnetic pulse valve, sequential injection of compressed air filter cleaning, so dust resistance remain within the limits set in order to ensure the efficiency of the processing power and dust precipitator. After the cleaning by differential pressure setpoint control device or cleaning time setting automatically shut off valve in a room, according to set procedures to open the electric pulse valve, stop the wind were blowing, blowing with compressed air and instantly make the filter increased internal pressure polyethylene, shake off the dust bag carried on (even fine dust can also stick more thoroughly cleaning) to the ash bucket, ash discharged from the institution. Filter dust which the wind host by low energy fan, barrel, bag, pulse controller, electromagnetic pulse valve, injection system components, cylinders arranged on the barrel body, and arranged a number of pulse valve and injection system. 1, adjust the pulse jet control device, locking pulse interval and pulse width, and complete all the electromagnetic pulse valve drive pulse cycle and cycle interval to ensure dust running resistance within the set range, the timing of the implementation of the ESP dust cleared . 2, every 2-3 months to remove the bag, dry air in the filter dust collection blowback blowing, cleaning. Filter to enhance filtering capabilities. Pulse induced draft ESP features: compartment stop the wind pulse cleaning technology to overcome the shortcomings of conventional pulse warehouse roof and sub-room cleaning dust precipitator, strong cleaning ability, dust, high efficiency, low emission concentration air leakage rate is small, less energy consumption, less steel consumption, small footprint, reliable, good economic returns. Blower pulse dust collector technical parameters: Filter area: 24 square meters filter: 14 exhaust volume:> 1500 m3 / h filtration efficiency of> 99.9% noise standards <75 db pulse cleaning methods to clean up clean-up can work for compression air 4 - 6 bar control board power 220V / 50Hz blowback hours 0.1-0.3 seconds (factory setting 0.1 seconds) Blowback interval 5--90 seconds (factory setting 28 seconds).
