Notes:
- Air consumption: The air consumption listed above is based on centralized air supply in the plant. If a dedicated air compressor is installed, multiply the listed values by 1.3.
- Air volume basis: The air volume is calculated at a filtration velocity of 1.2 m/min. It is intended for direct selection when the dust concentration at the source is below 30 g/Nm³ and the filtration velocity is unknown; otherwise follow the standard selection procedure in this manual.
- Inlet concentration limit: The inlet dust concentration limit applies only to certain process equipment in the cement industry. For other industries, refer to the concentration limits specified for other types of baghouse dust collectors.
- Air slide: Air slide specification 300 mm, air volume required for the permeable layer 2.0 m/min, air pressure 5860 Pa. Fan selection and duct configuration are the responsibility of the buyer.
- Cleaning controller: If the inlet dust concentration is below 700 g/Nm³, a dust collector with a screw conveyor should be selected. Input and output voltage 220 V; the controller is supplied by the manufacturer.
What Is a Pulse-Jet Baghouse Dust Collector?
A pulse-jet baghouse dust collector (also called a bag filter or fabric filter) is an air pollution control device that removes dust and particulate matter from flue gas and process exhaust. Dust-laden gas enters the hopper and rises into the filter chamber, where it passes through the filter bags. Dust is captured on the outer surface of the bags while clean gas is discharged through the top outlet. A pulse-jet system periodically injects high-pressure compressed air into the bags, causing the accumulated dust cake to fall into the hopper for discharge, keeping filtration performance stable over long-term operation.
