Explosion relief devices have the advantages of simple structure, sensitivity, accuracy, no leakage, and strong discharge capacity. It can explode and release pressure under specified temperature and pressure, ensuring the safety of people's lives and national property. Explosion relief discs are widely used in large-scale devices such as dust collectors, pipelines, pressure vessels, etc.
In recent years, accidents caused by dust storms have become increasingly frequent, environmental inspections have become stricter, and industrial safety has also attracted more attention. In the industrial production process, once equipment such as dust collectors explode or overpressure occurs, the explosion relief plate can timely and effectively release the overpressure caused by the superposition of explosion shock waves. When the pressure rises to the static opening pressure of the explosion relief plate, the explosion relief plate opens to release pressure, in order to prevent the explosion pressure from exceeding the structural strength limit of dust collectors and other equipment, protect the safety of equipment and production personnel, and reduce the severity of explosion accidents.

Function of Dust Explosion proof Membrane (Dust Explosion proof Membrane) in Dust Removal Box:
1. Extinguish the burst flame - No burst flame can escape, providing a safe operating environment.
2. Retention and explosion of dust - Capture process materials and eliminate potential harmful substances from entering the environment.
3. Control the bursting pressure - absorb the peak bursting pressure, protect personnel and the surrounding environment from bursting pressure damage.
4. Control the explosion temperature - absorb the explosion fireball and keep the surrounding environment temperature almost unchanged.

There are three main ways to prevent dust explosions: explosion venting, explosion isolation, and explosion suppression
Explosion relief: By using a pressure relief device to release the explosive pressure in advance, the equipment is protected from damage.
Explosion proof: A explosion-proof valve is used to block the explosion and prevent the spread of flames.
Explosion suppression: Firstly, the detection device detects the sparks formed, and then feedback activates the fire extinguishing device to instantly extinguish the fire and prevent the occurrence of explosions.

Explosion relief tablets are widely used in industries such as grain, metallurgy, chemical, power, light industry, pharmaceuticals, tobacco, mechanical processing, and solid waste disposal. The equipment used includes cyclone separators, bag filters, dust collectors, filter cartridges, pneumatic conveying, rod or ball mills, bucket elevators, drying and drying ovens, rolling mills, buildings, etc. Mainly used in working environments with low pressure, room temperature, and large explosion-proof surfaces, such as dust collectors, dust removal pipelines, and elevators.

In the past, we often used to install a venting plate on the dust collector to release the overpressure caused by dust storms. However, installing indoor equipment in this way is not permitted by the safety supervision department, as it can endanger surrounding personnel and equipment. The pressure waves and flames generated by explosive explosions may cause secondary or multiple explosions, posing greater risks. So using explosion-proof plates alone is unreliable for dust collectors. Therefore, we recommend using flameless venting and isolation technology (which is more economical) or explosion suppression and isolation technology to protect production safety.
