Description

Dust explosion-proof ventilation cavity Technical Field The utility model relates to the technical field of industrial production, in particular to a dust explosion-proof ventilation cavity. Background In industrial production, the explosion risk of combustible dust is always a major safety hazard. When dust concentration reaches explosion limit and there is the ignition source, very easily cause explosion accident, probably lead to equipment damage, casualties and production interruption, at present, dust explosion-proof mainly relies on ventilation system to reduce dust concentration, utilize the inside atomizing subassembly of ventilation cavity to moisten the dust, the dust granule after moisten falls to the collection frame in to combine pressure release device release explosion energy, but traditional ventilation cavity adopts straight-through structure mostly, the dust subsides the effect poor, can't effectively reduce explosion risk, and conventional pressure release mouth adopts disposable burst disk or spring valve, easily produce the metal splash during the explosion, easily cause secondary accident. A dust explosion-proof ventilation cavity is developed to solve the problems. Disclosure of utility model The utility model provides a dust explosion-proof ventilation cavity, which aims to overcome the defects that the traditional ventilation cavity mostly adopts a straight-through structure, the dust sedimentation effect is poor, the explosion risk cannot be effectively reduced, a conventional pressure relief opening adopts a disposable burst disc or a spring valve, metal splashes are easy to generate during explosion, and secondary accidents are easy to cause.
