PPW series air box pulse bag type dust collector combines the advantages of various types of dust collectors such as air blowing and blowing pulse, which overcomes the shortcomings of insufficient kinetic energy when the chamber is back blown, thus expanding the scope of use of the bag filter and improving the collection. Dust efficiency extends the life of the filter bag. He can not only purify general dust-containing gas, but also treat high-concentration gas with an inlet concentration of 1300g/mn3, and become a finished product recycling equipment matched with O-Sepa classifier and vertical mill. Under the new environmental standards (emission concentration, thermal equipment 100mg//mn3, ventilation equipment <50mg//mn3), not only widely used in the cement industry, but also widely used in the power, chemical, metallurgical steel industry.

PPW series air box pulse bag type dust collector consists of four parts: box, bag room, ash bucket, inlet and outlet, and is equipped with pillars, ladders, railings, compressed air piping system, cleaning control mechanism and so on.

The main design feature of PPW series air box pulse bag type dust collector is that there is no venturi tube on the upper part of the filter bag, and there is no blowing pipe. Instead, the pulse valve is used to directly blow compressed air to the clean air chamber to clean the filter bag. . This not only reduces the resistance of the blowing work, but also facilitates the detection and bag change from room to room.

PPW series air box pulse bag type dust collector integrated chamber back-blowing and blowing pulse cleaning all kinds of bag dust collectors, overcomes the shortcomings of insufficient back-washing dust-removing strength, and simultaneous pulse-cleaning phase filtration. Therefore, the application range of the bag dust collector is expanded, and since the structure of the dust collector of this type has its characteristics, the extraction rate extends the service life of the filter bag.

PPW series air box pulse bag type dust collector can be used as crusher, dryer, coal mill, raw material mill, grate cooler, cement mill, packaging machine and dust collection equipment of various warehouses. It can also be used as dust removal equipment for other industries.

PPW series air box pulse bag type dust collector can be widely used in cement factory crushing, packaging, storage top, clinker cooler and various grinding machines and other dust collection systems, such as for coal grinding dust collection, to add explosion-proof explosion-proof Measures, the structure of the dust collector is also changed accordingly, and it is also suitable for dust collection of gas with extremely high dust concentration. For example, the grinding system with O-Sep powder washing machine has a gas dust concentration of up to 1000G/M3 or more. The dust collector collects dust, and the cyclone dust collector is not provided for the first stage dust collection.

PPW series air box pulse bag type dust collector is also used for dust collection of metallurgical, chemical, mechanical and civil boilers in addition to the cement industry. The material of this series of dust collector filter bags is generally made of polyester needle felt, allowing the use temperature. Less than 120 ° C. If the filter bag is made of aramid needle felt, it can be used up to 210 °C. However, the filter material of this material is expensive. If the temperature of the treated exhaust gas is higher than the allowable temperature of the above filter material, the temperature should be taken before the exhaust gas enters the dust collector.

FMQD (PPC, PPW)-III type air box type pulse bag type dust collector works:

When the dust-containing gas enters the dust collector from the air inlet, it first hits the inclined partition in the middle of the air inlet, and the airflow turns into the ash bucket, and the airflow speed becomes slow. Due to the inertia, the coarse dust in the gas directly falls into the dust. The ash hopper plays the role of pre-collecting dust. After entering the airflow of the ash hopper, it folds up and passes through the filter bag with the metal aging frame inside. The dust is trapped on the outer surface of the filter bag, and the purified gas enters the upper part of the filter bag chamber. The clean room is collected into the air duct to discharge the air inlet of the FMQD32 type dust collector and is placed on the ash hopper. After the airflow enters the ash hopper, it first hits the baffle at the end of the air inlet pipe, and its function is the same as the above principle. The casing is divided into a plurality of independent dust collection chambers by means of partitions, and each of the dust collection chambers is cleaned in turn according to a given time interval. Each dust collecting chamber is equipped with a poppet valve, the poppet valve is closed when the dust is cleaned, the filtered air flow passing through the dust collecting chamber is cut off, and then the pulse valve is opened, and high pressure air is sprayed into the filter bag to filter the dust on the outer surface of the bag. . The pulse blowing width and the cleaning cycle of each dust collecting chamber are automatically and continuously performed by a dedicated cleaning program controller.
