Summary
The back blowing bag filter condenses the advantages of all kinds of bag duster both at home and abroad. It is a new type of dust removal device which combines the mechanism of cyclone dust removal and filter dust removal mechanism, and uses special cleaning methods to remove dust. The direct scour filter bag with high speed dust air flow is avoided and the service life of filter bag is prolonged; the clean air source of the back blowing dust source is introduced from the clean air flow after purification, which reduces the temperature difference between the air flow of the back blowing air and the Dust Collector and reduces the condensation phenomenon to the minimum limit.
Scope of application
The products are widely used in mine, metallurgy, machinery manufacturing, foundry, chemical, papermaking, refractory, cement, asbestos, industrial kiln and other industries, such as material recovery, flue gas dust control.
Working principle
After the dust air flow is cut into the dust collector, the large particle dust is separated and falling into the ash bucket first, and the small dust particles are suspended in the gas through the airflow distribution device, entering the filter chamber evenly, dispersing in the gap between the filter bags and being blocked by the filter bag, and the purification gas flow is discharged by the main fan.
Structure form of bag type dust collector
1. According to the shape of the bag, it can be divided into flat bags (trapezoidal and flat shaped) and round bags (cylindrical).
2. According to the way of entering and leaving the wind, it can be divided into: the downward wind and the upward wind, the wind and the direct current (only the plate-like flat bags).
3, according to the bag filter method is divided into: external filtration and internal filtration. The filter material consists of cotton fiber, wool fiber, synthetic fiber and glass fiber. The filter material made of different fibers has different properties. The commonly used filter material is 208 or 901 terylene flannelette, the use temperature is not more than 120 degrees C, the glass fiber filter bag after the silicone resin treatment, the temperature is generally not more than 250 degrees C, the cotton wool fabric is generally applicable to no corrosion; the temperature is below 80-90 centigrade gas.
Features of bag type dust collector
1, the dust removal efficiency is high, it can trap small particles with a diameter larger than 0.3 microns, and the efficiency of dust removal can reach more than 99%.
2, the use of flexible, handling air volume by hundreds of hours per hour in the room, small square meters of square meters near the machine tool to hundreds of thousands of cubic meters per hour, directly set up as a unit, also can be used as a large dusting room, that is, "bag house".
3, the structure of bag filter is relatively simple, stable operation, less initial investment (compared with ESP), easy maintenance. Therefore, the bag filter is widely used to eliminate dust pollution, improve the environment and recycle materials.
4. The key filter material of bag filter is now in service for more than 2 years, and has achieved 4-6 years' performance.
5. In dry and semi dry desulphurization systems, the role of SO2 in flue gas is further reduced.
