The utility model relates to a physical activation gas blasting device, and belongs to the technical field of engines. According to the utility model, the solid blasting technology is adopted to replace the existing gas blasting technology, and the change reduces the requirement on the sealing performance of the device shell, so that the shell structure can be formed in an integrated welding manner, the risk of leakage is avoided, and the process and the structure of the device are simplified through the change of blasting materials. Meanwhile, due to the fact that the dry ice is instantly vaporized under the action of the catalyst, high-pressure carbon dioxide gas is generated to act outwards, the good blasting effect is achieved, and the blasting power is high. Furthermore, the sealing structure composed of the plug, the sealing ring and the gasket is simple in machining process, meanwhile, the acting force direction of gas generated after blasting can be controlled, and the safety of blasting mining is gre
