Host pulse bag filter dust collector pulse bag host 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, high collection efficiency emission concentration is low, small leakage rate, low energy consumption, low steel consumption, small footprint, reliable, good economic returns. Suitable for recycling metallurgy, building materials, cement, machinery, chemicals, power, light industry, dusty gas purification and materials. As a result of the sub-room to stop the wind pulse cleaning, blowing a thorough cleaning can achieve the purpose, so extend the cleaning cycle, reducing the energy consumption of cleaning, compressed air consumption can be greatly reduced. Maintenance cartridge can change without stopping the system fan, system uptime divided chamber conditions. Cartridge opening up elastic ring, good sealing performance, solid and reliable. Filter keel are polygonal, the bag and the keel reduce friction and prolong the life of the cartridge, and easy unloading bags. Using the upper pumping bag way, when changing the skeleton out of the bag after the dirty bag hopper into the lower part of the box, remove the manhole, improved operating conditions for the core, box with airtight design, sealing, inspection doors excellent sealing materials, production process to kerosene leak, air leakage rate is very low, the inlet and outlet duct layout compact, low airflow resistance. Indoor dust alias structure, indoor dust collector, pulse induced air dust collector, pulse cleaning dust collector and so on. Host pulse bag filter is mainly used for indoor dust host. First, the pulse bag filter which consists of low-energy host 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 spray blowing system. Second, the pulse bag filter works by a host of work produced in the induced draft fan pressure inside and outside the bag, so that the outside of the particulate dust bag henchmen, led by the fan clean air, including dust, gas provided by one or two air inlet filter bag Dust blowing system using pulse cleaning formula, due to pulse controller and solenoid valve. For intermittent injection bag to continuously remove dust bag attached to the surface. Third, the use of pulse bag dust collector host. 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 will remove the filter, dry air in the filter dust collection blowback blowing, cleaning. Host pulse bag filter dust and gas from the inlet into the dust the cabinets, the role of small dust particles due to a variety of effects cartridge, the cartridge wall is entrapment. Purified gas through the exhaust outlet cartridge box. With the use of time of growth, the dust cartridge surface adsorption increased, decreased permeability of the filter cartridge, so that dust resistance increasing. To ensure dust resistance control within a limited range, signaled by the pulse controller, sequential open electromagnetic pulse valve, compressed air within the package by the spray jet to the corresponding hole injection tube venturi tube (called once the wind), and at high air flow through the venturi tube several times in a wind-induced ambient air (called secondary air) into the cartridge, resulting in the rapid expansion of inter-cartridge, due to the impact of the role of reverse pulse flow soon disappeared, and a sharp contraction of the filter cartridge, such that the product dust attached to the outer wall of the cartridge is cleared. Dust fall into the gray base.
