A passive mechanical explosion isolation valve is positioned in the inlet ducting downstream from the dust collector. This mechanical barrier is held open by the process air and is slammed shut by the explosion’s pressure force, preventing flames from propagating further upstream through the ducting.
Almost all industrial manufacturing, processing or packaging applications generate dust as a side effect. Many of these dusts are both combustible as well as explosive, and removing them from the work place can significantly reduce the risk of serious accidents. It is estimated that there are approximately 2,000 dust explosions in Europe annually. Most of these are minor but some are very destructive. So by extracting the dust, the risk in the production is reduced, but unless the extraction system is safe the risk is just moved.
