Detailed Product Description: | An overview of PPW type offline pulse bag filter is the introduction of the United States Fuller's technology based on the absorption German precipitator technology advantages. It combines the advantages of the sub-room cleaning and jet pulse cleaning dust and other various classes, to overcome the shortcomings of the sub-room cleaning dust strong enough, with blowing pulse cleaning and filtering the same time "re-adsorption", the use of clean energy Offline gray mode, with cleaning power, good cleaning effect, low system resistance, long life filter bag, dust efficiency, widely used in cement enterprise-grinding, crushing, packaging, library roof, batching systems, such as dust . It can not only purify the dust and gas in general, can be used directly as a vertical mill, O-SePa finished separator and other process equipment collected. In addition to the cement industry, but it can also be used for food, light industry, mining, power, chemical, metallurgy and other industries dust. This series of dust by a different number of rooms, and a different number of bags per room, composed of a variety of different specifications, the bag has 32,64,96,128 per room are four bags a diameter of 130, bag length features 2450,3060 two kinds. Second, the structure and working principle, structure of the dust from the cabinet, the cabinet, under the cabinet, part of the ash discharge device and pulse cleaning equipment, electrical control systems. (1) the box: Includes openable roof, flower plate, pulse valves, poppet valves, net gas chamber; (2) Case: Includes bag, bag cage and the inlet and outlet; (3) the box and hopper include: columns, ash bucket, access door; (4) the ash discharge device include: screw conveyors, air chute, cinder valve lock wind; (5) the control section: PLC control cabinet. 2, the system works in the role of the main blower, dust and gas from the inlet into the dust, in the role of both flow plate, the steering flow into the hopper. Due to slow the velocity, inertia and its own weight plus the dust, coarse dust particles directly into the hopper, the ash discharge device, other lesser fine dust with the air upwards and is adsorbed on the outer surface of the bag, the bag After filtration, the clean gas enters the box net gas chamber, aggregated to the exhaust duct. PPW32 series precipitator inlet located within the hopper, dust and gas into the hopper after the first encounter baffle inlet pipe ends, and its role in principle the same as above. With the continuous filtration, dust bag on the outer surface of the piled up, the system is running, gradually increasing resistance, to ensure the system is operating normally, the resistance ceiling precipitator maintained within the range 1200-1700Pa when more than this limited range When, PLC control cabinet will set the program (a certain time interval or cleaning cycle) in the tri-state cleaning. The key technology is the use of the pulse filter cleaning compartment offline mode. Its cleaning process is shilling a bag chamber poppet valve closed, cutting off the air flow of the chamber so that it is in a state without flow through, and then open the pulse valve pulse cleaning, dust bag attached to the outer surface of the cake to be sprayed blown down, in full settlement of dust fall into the hopper, the poppet valve is opened, the chamber again into the filter state, followed by the next room offline for cleaning, so the cycle-by-room cleaning, again and again. Such cleaning method is not only a thorough cleaning, and avoid secondary dust produced after injection, good cleaning effect.
