Coal dust collector

Coal dust collectorIt belongs to a type of industrial dust removal equipment, mainly used in scenarios such as coal-fired boilers, coal powder preparation systems, and crushing and screening processes. It intercepts coal powder particles through efficient filtration technology and has safety features such as explosion prevention and anti-static.

Core functions

Dust separation: The coal powder particles are intercepted by a filtering device (such as an anti-static cloth bag), and the purified gas meets the emission standards.

Explosion proof design: Adopting explosion-proof structure, pressure relief device and anti-static materials to reduce the risk of dust explosion.

Resource recycling: Some equipment also has the function of recycling coal powder, improving resource utilization efficiency.

Working principle

The gas containing coal powder enters the dust collector under the action of the fan, and the dust is intercepted by the filtering material (such as a bag), and the clean gas is discharged; The filtered dust is removed from the bag and collected through a cleaning system (such as pulse blowing).

Application scenarios

Coal processing process: including coal powder preparation system, crushing and screening, conveying system and other processes that are prone to producing high concentration coal powder.

High risk environment: Suitable for flammable and explosive coal dust environments, such as coal mine screening workshops, coal grinding equipment, etc.

Performance Requirements

Efficiency and safety: The dust removal efficiency needs to reach over 99%, while also meeting safety standards such as explosion prevention and high temperature resistance.

Economy: It is necessary to balance equipment costs, maintenance expenses, and service life.

Through the above design, the coal powder collector plays a key role in controlling pollution and ensuring production safety.

Coal dust collectorMain structural components

1、 Box structure

Clean air chamber: including fans, partition cylinders, valve discs, and maintenance ports, used for discharging purified gas.

Filter room: equipped with anti-static filter bags, pulse valves, spray pipes, flower plates, filter bag skeletons, etc., with the core function of dust interception and separation.

Ash hopper body: located at the bottom of the dust collector, equipped with a screw conveyor and an ash discharge valve, used to collect and discharge settled coal powder.

2、 Filtering device

Filter bag and frame: Made of anti-static material (such as polyester velvet or fiberglass filter bag), suitable for high temperature and explosion-proof requirements.

Flower board: supports the filter bag and ensures even distribution of gas. The material should be pressure resistant and corrosion-resistant.

3、 Ash cleaning system

Pulse blowing device: consisting of a pulse valve, blowing tube, and control instrument, it uses high-pressure gas to instantly blow and remove dust from the filter bag.

Compressed air system: including gas tanks, oil-water separators, and pipelines, providing a stable air source for dust cleaning.

4、 Air intake and exhaust system

Inlet pipe: guides dusty gas into the dust collector, often in conjunction with a cyclone separator for initial filtration of large particulate dust.

Ash discharge device: including ash hopper, ash discharge valve or drawer/ash bin structure, supporting centralized collection and discharge of dust.

5、 Auxiliary components

Explosion proof device: Explosion relief valve, anti-static design, reducing the risk of coal powder explosion.

Control system: Integrated pulse controller, fan start stop and monitoring module to achieve automated operation.

Through modular design, the coal powder collector efficiently integrates functions such as filtration, ash cleaning, and ash discharge, adapting to the dust control needs of mining, power plants, and other scenarios.
