It can be applied in equipment such as cyclones separator, bag-type dust collector, dust collectors, cartridge filters, pneumatic conveying ball mills, rod mills or ball mills, bucket elevators, dryers and ovens, roller grinding, buildings, etc. The device is mainly composed of a venting panel and a flameless venting device, and installed on the equipment which should be protected. The venting panel is closed during normal operation. Once the dust explosion occurs within the device, the force imposed by explosion overpressure on the explosion venting plate will exceed the opening pressure of the explosion venting plate, then the explosion venting plate will break and crack along the gap, so that explosion pressure will be relived from the gap of fire arrester, and the flame will be quenched by the quenching and cooling action of flame extinguishing layer to prevent explosion pressure and high temperature generated by the flame from harming operators or equipment around it. It is generally composed of a venting panel which is installed with a fire arrester.
