Concrete mixing station host provider indoor dust mainly used for indoor dust host. An indoor dust host it by low energy 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, indoor dust hosts works by the induced draft fan work produced in the filter and external pressure, so the outer granular dust partisan filter, clean air drawn by the fan, dust containing gas is supplied 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. Third, the use of indoor dust 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. Concrete mixing station host provider indoor dust dusty gas from the inlet into the dust cabinets, small dust particles due to the effect of 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. Suppliers concrete mixing station indoor host 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, high collection efficiency, emissions low concentration, small leakage rate, low energy consumption, low steel consumption, small footprint, reliable, good economic returns. Concrete mixing station host provider indoor dust applicable to the recovery in 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.
