Langfang pulse dust collector manufacturer of indoor 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 low leakage rate is small, less energy consumption, less 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. Pulse host indoor dust mainly used for indoor dust host. A pulse dust collector which consists of low-power indoor host Fan, barrel, filters, pulse controller, electromagnetic pulse valve, injection system components, cylinders arranged on the barrel body, and arranged a number of pulse valves and injection systems . Second pulse dust collector works by a host of indoor fan cited work produced in the filter and external pressure, so that the outside of the particulate filter dust gang, led by the fan clean air, including dust, gas provided by one or two air intake, filter dust using a pulse counter- blowing blowing system, the role of pulse controller and solenoid valve. Intermittent injection for the filter to continuously remove dust attached to the filter surface.
