Introduction and characteristic analysis of bag filter
Dec 02, 2021The body structure of the bag filter is mainly composed of an upper box body, a middle box body, a lower box body (ash bucket), ash cleaning system and ash discharge mechanism. When the dust-laden gas enters the ash hopper from the inlet pipe of the lower part of the dust collector through the deflector, the coarse dust will fall into the ash hopper due to the collision of the deflector and the reduction of gas velocity, and the remaining fine particles will follow. The gas enters the filter bag chamber. Due to the inertia, diffusion, barrier, hooking, static electricity and other effects of the filter material fiber and fabric, the dust is trapped in the filter bag, and the purified gas escapes out of the bag and is discharged through the exhaust pipe. The dust on the filter bag is removed by spraying pulse airflow, so as to achieve the purpose of dust removal. The removed dust falls into the ash hopper and then is discharged by the ash discharge device.
Compared with electrostatic precipitator, the bag filter is cheaper to manufacture, has no requirements on the nature of the dust, and the dust removal efficiency can reach more than 99%.
The bag filter has the following characteristics:
1. The dust removal efficiency is high, up to 99% or more.
2. It has strong adaptability and can handle different types of particulate pollutants.
3. The operation is stable, and the dust concentration of the inlet gas changes greatly, which has little effect on the dust removal efficiency.
4. Simple structure, flexible use, easy to recycle dust.
The bag filter can be used in coal-fired power generation industry, waste incineration industry and cement industry, etc. In the future, the application of bag filter will become more and more extensive, and the filter accuracy and emission standards of bag filter will become more and more stringent. As the filter bag that produces the heart of the bag filter, Yuanchen Technology always follows the footsteps of the times, devotes itself to the research and development of high-efficiency and long-lasting filter bags, and contributes to the beauty of the world's environment and human health.
