Application | Explosion-proof safety of dust collection devices

There are very many explosion accidents involving dust collection devices. Here are some methods to protect against them.

Due to the high frequency of explosion accidents involving dust collection systems, many dust collector manufacturers install explosion-proof devices. The risk of explosion arises not only from dust generated by other equipment but also from sparks and smoldering. A particular concern is the cleaning of filter elements. Very fine dust can spread uniformly within the dust collector, potentially leading to an explosion when combined with an ignition source. Therefore, indoor dust collectors are equipped with frameless explosion venting devices such as Q-Box and Q-Rohr for venting. Furthermore, in the case of hazardous materials, the use of Q-Bic can also help suppress explosions. Outdoor dust collectors can be protected with explosion vents if they are in a ventable environment. The selection of explosion vents varies depending on the installation conditions of the dust collector. If transportation or traffic routes are near the explosion vent, TARGO-VENT type deflection plates are used to direct the flames and shock waves from an explosion to designated areas.

[Note] Importance of Understanding the Overall Picture The protection of each individual component of the plant is of equal value to the protection of the entire system. Special attention is required for adequate isolation devices and protection against overpressure. By surveying the entire plant and ensuring that all individual protective measures are in place, explosion safety measures become safer and more economical.
