Una valvola di isolamento meccanico passivo contro le esplosioni è posizionata nel condotto di ingresso a valle del depolveratore. Questa barriera meccanica è tenuta aperta dall'aria di processo e viene chiusa dalla forza di pressione dell'esplosione, impedendo alle fiamme di propagarsi ulteriormente a monte attraverso il condotto.
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.
