PPCS series of air box pulse bag dust collector

PPCS series of air box pulse bag dust collector

Belong to: Smoke and dust control equipment

PPCS type air box pulse bag filter is a new type of high-efficiency bag filter optimised and developed by our company on the basis of the technology of PPC series bag filter of American Fuller Company. The product has the characteristics of overall ash cleaning in the chamber and adopts the form of large-size pulse valve ash cleaning, which has the features of strong ash cleaning ability, long service life of the filter bag, compact structure, small footprint, few mechanical action parts, convenient bag changing, small maintenance workload, stable and reliable operation, etc. It is widely used in building materials, cement, metallurgy and other industries. It is widely used in building materials, cement, metallurgy, machinery, chemical industry, and refractory industry.

 

It integrates the advantages of various types of bag dust collector, overcoming the advantages of chamber blowing and blowing pulse cleaning, and overcoming the shortcomings of insufficient strength of chamber blowing, blowing pulse cleaning and filtration at the same time, thus expanding the scope of application of bag dust collector, due to the structure of this type of dust collector has its own characteristics, so it improves the dust collection efficiency, and prolongs the service life of the filter bag.

It is suitable for dust collection of coal mill, to be added with anti-flame and explosion-proof measures, and the structure of the dust collector should be changed accordingly, and it is also suitable for dust collection of gases with very high dust concentration, such as the milling system of the powder selector. Gas dust concentration up to 1000g/m³ (standard condition) or more, the use of this series of dust collector, can not be set up cyclone dust collector for primary dust collection. In addition to the cement industry, it is also suitable for metallurgy, chemical industry, machinery and civil boilers and other exhaust gas dust collection. The material of the filter bag of this series dust collector is generally made of polyester felt, the permitted continuous use temperature is less than 120℃, if the filter bag is made of aramid needle felt, the permitted use temperature can be up to 210℃, but the price of this kind of filter material is expensive. If the temperature of the exhaust gas is higher than the allowable temperature of the above filter media, cooling measures should be taken before the exhaust gas enters the dust collector.
This series of dust collector is outdoor type, which consists of different number of chambers and different number of bags in each chamber to form a variety of different specifications. The number of bags in each chamber is 32, 64, 96, 128, a total of 33 specifications for the whole series, the diameter of the filter bag is 130mm and the length of the filter bag is 2450mm and 3060mm. This series of dust collector can be operated under negative or positive pressure without any change in the structure of the body, the dust collection efficiency can reach more than 99.9%, and the dust concentration of the purified gas is less than 20mg/m³ (standard condition), the main technical performance of this series of dust collector is shown in the table below. If it is used in cold area, it is necessary to add the heat preservation layer, and the shell of the dust collector should be changed accordingly.
