Fire prevention methods for bag filter

Bag filter is a modern and efficient dust removal equipment. The dust removal efficiency is as high as 99%, resistant to high temperatures, and highly favored by industrial production. Its emergence is not only beneficial to environmental protection, but also beneficial to human health. However, bag filters often face high temperatures and corresponding measures should be taken to prevent fires from occurring.
During the dust removal process, if high-temperature flue gas is encountered, unburned high-temperature dust and explosive gases often appear, often accompanied by spontaneous combustion and electrification. After entering the dust removal system, static electricity will accumulate due to friction with the dust removal bag, which can easily lead to combustion and explosion accidents, with very serious consequences. Therefore, when using a bag filter, fire and explosion prevention measures should be considered. The specific measures are as follows:

  1. In general, for fire safety, a combustion chamber or spark trap can be installed in front of the bag filter to ignite or capture unburned dust and gas, greatly reducing the occurrence of fires;
  2. The method of grounding conductive parts or burying conductive fibers into dust removal bags to prevent static electricity accumulation and reduce the risk of electrical fires;
  3. Due to the spontaneous combustion of dust, it is necessary to regularly clean the bag filter to prevent dust accumulation and reduce its natural rate.
