Overview

When installing a coal powder bag dust collector, since the collected dust is coal powder, there is a possibility of explosion. Therefore, the first consideration is to have an explosion-proof device. The dust bag uses anti-static polyester needle felt, and the fan and unloader should be explosion-proof equipment. The dust removal equipment of the coal conveying system is generally arranged in the operating station at the tail of the belt conveyor, that is, a dust hood and a circulating air duct are arranged on the coal guide groove at the coal point at the tail. There are also dust hoods arranged at multiple points in the coal bunker or the car dumping machine room for dust removal. The coal dust is collected by the dust collector and then falls into the system belt through the secondary recovery coal pipeline.

Product Details

Coal powder bag dust collectorThe explosion-proof device is mainly used to prevent the sudden increase of gas pressure inside the dust collector and avoid the danger of explosion. The following are several common explosion-proof devices and their principles:

1. Explosion proof pulse valve: The pulse valve is one of the important components of the bag filter. Its function is to control the amount of compressed air entering the dust collector by periodically opening and closing, thereby cleaning the dust filter bag. The use of explosion-proof right angle pulse valve or straight through pulse valve can effectively prevent the sudden increase of gas pressure inside the dust collector and avoid the danger of explosion.

2. Explosion proof fan: The fan is the power source of the bag filter, which sucks in gas to send dusty gas into the filter for dust removal. By using explosion-proof fans, the speed of the fan can be effectively reduced in the event of an explosion inside the dust collector, preventing the fan from becoming a source of fire.

3. Installing explosion-proof valves on pipelines: Installing explosion-proof valves on the inlet and outlet pipelines of the dust collector can effectively prevent flames from spreading through the pipeline during explosions, causing larger accidents. The function of the explosion-proof valve is to limit the explosion within a certain range and prevent the explosion from spreading to other parts.

4. Equipment body with explosion vent and explosion-proof plate: Installing explosion vent and explosion-proof plate on the body of the dust collector can release pressure through the explosion vent and explosion-proof plate when an explosion occurs inside the dust collector, avoiding equipment damage and personnel injury. The setting of the explosion vent should ensure pressure relief safety and not cause harm to the surrounding environment.

5. Anti static dust bag: Using a dust bag with anti-static function can effectively prevent the accumulation of static electricity, thereby reducing the risk of explosion. Static electricity accumulates on the surface of the dust removal bag, which may cause discharge and spark, leading to explosion accidents.

In conclusion,Coal powder bag dust collectorThe principle of the explosion-proof device is to reduce the risk of explosion inside the dust collector by controlling the amount of compressed air entering the dust collector, reducing the fan speed, preventing flame propagation, releasing pressure, and avoiding static electricity accumulation, ensuring equipment safety and personnel safety.
