Overview
Filter bag is a cylindrical filtration element constructed from high-strength synthetic or natural fibers. It operates via depth filtration and surface cake formation to capture particulate matter. Core manufacturing involves needle-punched felting or woven structures, ensuring structural integrity under continuous airflow.
Application
- Cement production: Baghouse filters in kilns and mills.
- Power generation: Fly ash collection in electrostatic precipitators.
- Metalworking: Dust extraction from welding stations and grinding machines.
- Chemical processing: Powder handling in pneumatic conveying systems.
Precautions
- Temperature range: Typically -20°C to 260°C depending on material.
- Pressure drop: Maintain differential pressure below 2500 Pa for optimal efficiency.
- Maintenance: Regular pulse-jet cleaning cycles required; inspect seams for abrasion monthly.
