Rupture disc type flameless pressure relief device

The utility model relates to the technical field of explosion pressure relief equipment, in particular to a rupture disk type flameless pressure relief device which comprises a base and a side plate fixed on one side of the base, baffles are fixedly connected to the front side and the rear side of the base, and an explosion buffering cavity is defined by the base, the side plate and the two baffles. A fire-retardant buffering piece used for sealing the explosion buffering cavity is fixedly connected between the base and the side plate, an explosion venting opening communicated with the explosion buffering cavity is formed in the bottom plate, and a rupture disk is detachably connected to the explosion venting opening. According to the pressure relief device, shock waves and flames generated by explosion are buffered through the explosion buffering cavity, pressure relief and fire retardance are achieved through the fire retardance buffering piece, and the problems that in the prior art, a pressure relief devi
