Problems solved by technology

Sometimes in the cleaning process, under the impact of high-pressure wind and strong airflow, the bag will also be greatly damaged, resulting in an increase in the concentration of dust in the discharged gas, and when the airflow containing more dust passes through the fan at high speed, it will cause the fan shell and Severe wear of the impeller

Abstract

The invention provides a special filter bag for a biological power plant. The filter bag comprises a filter bag body and a mounting ring, wherein the mounting ring is arranged at the mouth of the filter bag body; the filter bag body comprises base cloth which is needled from polyimide fibers and polytetrafluoroethylene fibers; a dust stopping face knitted from polyimide fibers, polyphenylene sulfide fibers and polytetrafluoroethylene fibers is arranged on the internal surface of the base cloth; a polytetrafluoroethylene fiber bottom layer is arranged on the external surface of the base cloth. The special filter bag for the biological power plant has the advantages of high abrasive resistance, better filtering effect, long service life and the like.

Description

technical field [0001] The invention relates to a filter bag, in particular to a special filter bag for a biological power plant. Background technique [0002] With the rapid development of China's economy, the output of steel, cement and coal ranks first in the world, and its power generation capacity ranks second in the world. These raw materials, energy industry production equipment and technology are relatively backward, resource and energy consumption is large, pollution is serious, and the amount of dust and smoke generated is huge, and the market demand for bag filter is also increasing. The key component of the bag filter is the filter bag, and its dust removal performance determines the quality of the bag filter. [0003] In the field of biological power plants, due to the wear and tear on the surface of the filter bag by the dust, small "acupuncture" holes will appear in the bag over time. Sometimes in the cleaning process, under the impact of high-pressure wind ...
