Working principle: the reversing explosion relief device is composed of reversing pipeline and bursting disc. After conveying dust containing gas or inflammable and explosive gas through the reversing explosion relief device, the gas flow direction changes 180 degrees. When the medium in the equipment is deflagration, the reversing pipeline can effectively reduce the impact force of deflagration in the pipeline by changing the flame propagation direction, and achieve an acceptable safety Horizontal, but can not completely cut off the flame and discharge pressure. The release piece shall be opened in time to release the pressure generated by combustion and explosion in the pipeline, so as to reduce the pressure in the vessel and prevent the vessel from explosion due to high pressure.
