Bag type dust collector for cement industry

In the production process of cement industry produce production is very serious for environmental pollution, was included in the high-polluting industries. For the dust generated in the cement production process, the dust removal methods currently used in the industry are mainly electric precipitator and bag type dust collector. The bag type dust collector filter because of its high efficiency, dust removal effect is widely used in cement industry. Based on different process characteristics, compared with bag-type dust collector, electric precipitator operation and maintenance costs are lower, but the effect is slightly worse. Due to the large amount of dust in the cement industry, the efficiency of electric precipitator is greatly affected by factors such as equipment performance, enterprise management level and production line condition, and the efficiency of dust collection is different, only a few cement enterprises can achieve national emission standards by electric precipitator. Because of this, the bag-type dust collector with relatively few constraints and higher dust removal efficiency has become the first choice of more cement enterprises to reduce dust emission at present. Bag type dust collector as the cement industry widely used energy saving equipment, has large capacity, high dust removal efficiency, good stability, and effectively improve the recovery of cement. Is a key construction projects for the cement industry energy-saving emission reduction With the intensification of pollution, the state has also paid more and more attention to the protection of the environment. Cement kiln dust emission standards dropped to 30mg / Nm3 (cement kilns and other thermal equipment) and 20mg / Nm3 (cement mill and other ventilation equipment). Bag type dust collector is the most effective equipment to control particulates, especially PM2.5 ultrafine particles. Compared with electrostatic precipitators, bag-type dust collector technology has a higher capture efficiency for fine particles, the removal efficiency of fine dust from 0.01μm to 1.0μm can reach 97% ~ 99%, even higher. In recent years, bag-type dust collector has become the development direction of particulate matter capture technology. The key of industry dust collection is to develop the filter with high efficiency, low resistance, long life and functional, especially for PM2.5 fine particles. Bag-type dust collector in the cement, steel, non-ferrous metals, power, chemical, and other industries have gradually replaced the electric precipitator.
