I produced a dedicated baghouse boiler flue gas temperature is high especially for the characteristics of the design, selection of high quality wear-resistant high temperature PPS needle felt filter bag or fluorine Gomez needle felt material, the working temperature up to 240 ℃, can handle up to a one-time 1000mg / m3 concentration of soot. Dust removal rate of 99% or more, soot treatment applies to various types of oil-fired boiler, coal-fired boiler, oil boiler, chain steam boiler, furnace, cupola, grate, hand burning furnace boiler. So you can easily cope with environmental testing worry. This series dust collector for outdoor type, number of rooms and different by different bag per room, composed of a variety of different specifications. Each room has a number of bags of 32,64,96 and 128 bags of four. Full range of 33 kinds of specifications, bag diameter are 130mm, 2450mm and 3060mm length bag two kinds. This series dust collector can be negative or positive pressure operation, without any change in the basic structure, the collection efficiency of up to 99.9%, purified gas dust concentration is less than 100MG / M3, this series dust collector such as for the cold area, when the outdoor temperature is -25 ℃ when heating is calculated, to additional heating device precipitator housing should be changed accordingly. Second, the structure and working principle: This series dust collector by the portion of the housing, ash bucket, ash equipment, brackets and pulse cleaning system formed. When the dust and gas from the inlet into the dust collector, first met in the middle of the ramp inlet separators, air will flow into the hopper steering, while the air flow slows down, due to inertia, so that the gas directly into the coarse dust hopper, played the role of dust in advance, the airflow into the hopper off and stand up with metal years through internal bag, dust trapped in the outer surface of the bag, gas purification into the bag after the upper chamber clean room, aggregated to the exhaust duct FMQD32 type precipitator inlet located on the hopper, the airflow into the hopper after the first run into the inlet tube end of the bezel, and its role on the same principle as described above. Shell separator into several separate collecting chamber, according to the given time interval, alternating tones for each cleaning dust collection chamber. Each room is equipped with a dust collection poppet valve, poppet valve closed when cleaning, cutting off air flow through the filter of the collecting chamber, then pulse valve is open, the inner bag is injected into the high-pressure air to remove the outer surface of the bag dust. Width and pulse jet dust collection chamber of each cleaning cycle, automatic continuous cleaning procedures carried out by a dedicated controller.
