Industrial Filter Bags
Filter Bags for Waste Incineration
Filter bags used in waste incineration are designed to handle the high temperatures and corrosive gases produced during the combustion process. Their main function is to capture fine particulate matter, heavy metals, and other harmful substances from the flue gases emitted by waste incinerators, ensuring compliance with environmental regulations and reducing air pollution. High temperature resistant needle felt filter bags are widely used in waste incineration due to their heat resistance.
Materials
- PPS (Polyphenylene Sulfide) Needle Felt.
- P84 (Polyimide) Needle Felt.
- PTFE (Teflon) Needle Felt.
- Fiberglass Needle Felt.
- Nomex (Aramid) Needle Felt.
- PPS (Ryton) Needle Felt.
产品详细描述
With the acceleration of global urbanization, garbage pollution is serious. Improper garbage disposal may cause serious air, water and soil pollution and occupy a large amount of land. How to solve the garbage problem has attracted great attention from the whole society.
Features of Waste Incineration Filter Bags
- High Temperature Resistance: These bags must withstand continuous exposure to temperatures ranging from 200°C to 260°C, and in some cases even higher.
- Chemical Resistance: Flue gases from waste incineration contain acidic and corrosive substances such as sulfur dioxide (SO₂), hydrochloric acid (HCl), and nitrogen oxides (NOₓ).
- Fine Particle Capture: Filter bags used for waste incineration need to capture ultrafine particulate matter (PM2.5) to prevent harmful pollutants from being released into the environment.
- Durable and Long Life: Due to the harsh conditions of waste incineration, filter bags are designed to have a long service life, reducing the need for frequent replacement and maintenance.
