What are the specific applications of industrial dust removal filter bags in industrial scenarios?

1. Heavy industry and energy fields
The smoke generated by coal-fired power plants contains a large amount of PM2.5 and sulfur oxides. Industrial dust removal filter bags work in an environment of 180-220℃ through high-temperature resistant materials (such as PPS or PTFE coated filter materials) to capture fly ash particles and ensure that the emission concentration is ≤10mg/m³, meeting the low emission standards.
The cement plant generates high-concentration dust (such as limestone powder and clinker powder) throughout the entire process from raw material crushing to finished product packaging. The use of moisture-proof and anti-condensation filter bags (such as glass fiber coated materials) can stably operate in a high temperature and high humidity environment of 200℃ at the head and tail of the kiln, with a filtration efficiency of 99.9%, significantly reducing the PM10 concentration in the workshop to below 5mg/m³, protecting the respiratory health of workers.

2. Chemical industry and special materials manufacturing
Acid mist (such as sulfuric acid mist), catalyst powder and resin particles generated in chemical production need to be intercepted by acid and alkali resistant filter bags (such as P84 fiber material). Chemical plants use bag dust collectors on PVC production lines, which not only remove 99% of dust, but also reduce the chemical adsorption of filter bags and vinyl chloride through surface coating technology to avoid material embrittlement.
Graphite and metal dust generated during the coating and slitting of lithium battery pole pieces have explosion risks. Anti-static filter bags (such as carbon fiber blended materials) conduct static charges through conductive fibers, combined with explosion relief valve design to ensure that dust concentration is less than 30% of the lower explosion limit, ensuring production safety.

3. Mechanical processing and manufacturing industry
Metal welding smoke contains heavy metal oxides (such as manganese and chromium). Pulse bag dust collectors are equipped with flame-retardant filter bags, which can capture 99% of submicron particles at an accuracy of 0.3μm.
The silica sand and metal chips produced by the casting process are filtered through high-wear-resistant filter bags. The filter bags have a lifespan of more than 20,000 hours. The recovered molding sand can be directly reused, reducing raw material consumption by 30%.
