Explosion proof pulse bag dust collectors for coal grinding system
The coal mill explosion-proof pulse bag dust collectors is an efficient dust removal equipment specifically designed for coal powder preparation systems, with explosion-proof function, which can effectively handle coal powder dust and ensure production safety.
- Equipment Overview
-Purpose: Mainly used for collecting and purifying flammable and explosive dust generated by coal mills (coal powder preparation systems), commonly found in industries such as cement, electricity, metallurgy, etc.
-Core functions: Efficient filtration of coal powder dust (fine particle size), pulse cleaning, explosion-proof design.
- Working principle
-Filtering: The dusty gas enters the dust collector through the air inlet and is filtered through the surface of the anti-static filter bag. The dust is intercepted and the purified gas is discharged.
-Dust removal: Using compressed air pulse blowing technology, the accumulated dust on the filter bag is removed at a fixed time or pressure difference to maintain filtration efficiency.
-Explosion proof mechanism: Measures such as explosion-proof discs, explosion-proof valves, spark free design, and inert gas protection (such as CO ₂ or N ₂) are taken to prevent dust explosions.
- Core Structure and Characteristics
(1) Explosion proof design
-Explosion relief device: Install explosion relief discs or explosion-proof doors in the box to quickly release pressure during an explosion.
-Anti static filter bag: Made of conductive fiber material to prevent static electricity accumulation.
-Spark detection and fire extinguishing system (optional): Real time monitoring and extinguishing of fire sources.
-Explosion proof valve: prevents the spread of explosive flames to downstream equipment.
(2) Efficient filtration
-Filter bag material: Anti static polyester needle punched felt or laminated filter material is usually used, with a filtration efficiency of>99.9%.
-Pulse dust cleaning system: Automatic control of compressed air injection, thorough dust cleaning without damaging the filter bag.
- Advantages
-High safety: Multiple explosion-proof measures reduce the risk of explosion.
-Energy saving and environmental protection: Pulse cleaning has low gas consumption and meets emission standards.
-Automated operation: PLC control, real-time monitoring of parameters such as pressure difference and temperature.
-Long life design: The filter bag replacement cycle is long (usually 2-4 years).
