The boiler pulse bag filter

Processing air Filter wind speed high Out dust effect is good Stable performance

thisHGDM series boiler pulse bag filter is a kind of air processing, filter wind speed high, clear grey effect is good, reliable operation of the unit combined-type dust removal equipment, widely used in electric power, metallurgy, building materials, chemical industry and boiler, furnaces, garbage incineration flue gas and dust removal of material recovery.Working principleDust-contained gas pipe into the unit by diverting ash hopper in ash hopper diversion system under the guidance of large particles separated directly into dust ash hopper the rest into the dust in the air filter area, filtered through the purity of gas filter bag, above the body, lifting the, platoon duct eduction. With the filter, when the filter bag dust gathered to surface a certain amount, out dust control device by set according to program close ascension valve and open electromagnetic pulse valve injection, shake off the dust on the filter bag, fall into the gray ash hopper discharge valve eduction.This series has the bypass flue dust, when boiler (or incinerator), when activated, open bypass flue, in order to prevent the ignition pitched oil burning is bad, oil is stuck in the filter bag, fire will burn in the filter bag. When the boiler failure exhaust temperature more than the filter bag allowed temperature, open bypass.This series of filter also has a leak detection device, with multiple probe (every warehouse Zhi 1), 1 turbidity meter component, according to the smoke turbidity judge whether the filter bag leakage, at the same time in the ash hopper equipped with air cannon. Basic structureHGDM series pulse bag filter boiler by the assembly, the filter bag assembly, guiding device, pulse injection system, the grey system, control system and off-line protection system etc.1, body parts from the case on (net wind room), in case (filter room), the lower case (ash hopper), flue gas distributor, flower board, platform, staircase, supporting feet, wind path, the ash, heat preservation, color panel etc.2, the filter bag assembly: the filter bag frame, bags and hanging bags connection design USES lock device since, installation and easy to change, and can prolong the service life of the filter bag. The filter bag for sizes: Φ 130 * 2450 mm, Φ 130 * 6000 mm, Φ 160 * 6000 mm 3 kinds, the PPS acupuncture felt (Japanese PPS/PPCSI7, waterproof and oil processing).3, guiding device: use the international advanced into the wind way, unique design of flue gas distribution device, can not only effectively dust-contained gas distribution, and for large particle separation, avoid dust-contained gas scour the filter bag, and to further improve the dust removal efficiency, improve the service life of the filter bag.4, pulse blowing system: something united box, electromagnetic pulse valve, pressure fittings, nozzle tube, support etc. HGSM-5.6 following specifications for the whole case out dust, the rest of the specification in the filter bag is all on each has a compressed air nozzle tube. Running time, generally every a row of the filter bag set every 10 S pulse blow out dust once, time start-up an electromagnetic valve and will pulse blow compressed air spray into the filter bag out dust within.5, a grey system: the electricity vibrators (air bag), electric heater, grey position indicator composition, electric vibrators (air bag) ensure that dust has good liquidity.6, control system: mainly by pulse injection control meter, the HMC computer controller, thermal resistance thermometers, static pressure point, level indicator and measuring components.7 and off-line protection system: mainly by bypass valve, emergency water spray system, differential pressure device, level meter, the h_2s, pressure detection equipment, impulse control meter, the filter bag leak detection devices, so that the filter bag when damage to the police. Because the big tonnage boiler ignition and low load need fuel spray, will produce the massive oil gas directly into the flue gas emissions bypass piping, thus it can effectively protect the filter bag.
