Explosion-proof valves and explosion-proof devices for explosion-proof dust collectors

After an ordinary dust collector explodes, not only will the dust collector itself be seriously damaged or even scrapped, but it will also affect the safety of the surrounding environment. In severe cases, the flame will reach the workshop along the pipeline and cause a secondary explosion, causing damage to the factory building and casualties.

In order to prevent the dust collector from exploding, when designing an explosion-proof dust collector , explosion-proof valves and explosion-proof devices are installed on the dust collector body and pipelines to reduce risks. Different types of dust collectors install explosion-proof valves and explosion-proof devices at different locations.

In the bag type explosion-proof dust collector, the explosion-proof device is installed on the side or top of the dust collector, and the explosion-proof valve is installed on the main pipe. When an explosion occurs, the explosion-proof valve is closed under the action of the shock wave. The explosion pressure inside the dust collector continues to rise. When the explosion pressure point of the explosion-proof device is reached, the explosion-proof disc opens and flames are ejected from the explosion-vent. Due to structural reasons, in wet explosion-proof dust collectors, the explosion-proof device and explosion-proof valve are installed on the main pipeline. The explosion-proof device is close to the main body of the dust collector. The explosion-proof valve and explosion-proof device are generally used in combination.
