Abstract

The invention discloses a combustible gas explosion testing device in an explosion venting space. The explosion testing device comprises a fuel gas source (1), a pressure sensor (6), a pressure sensor (7), an infrared gas analyzer (17), a high-speed camera (18) and a closed chamber (19). The closed chamber (19) is of a full-scale reinforced concrete structure, and the rear side wall of the closed chamber (19) is of a full-steel plate structure. A front explosion venting hole (5) which is communicated with the outside of a room is formed in the front side wall of the closed chamber (19), and a rear explosion venting hole (10) which is communicated with the outside of the room is formed in the rear side wall of the closed chamber (19). A closed machine box (15) is arranged outside one side wall of the closed chamber (19). An anti-explosion draught fan (14) is arranged inside the closed machine box (15). A detonating fuse head (8) is arranged inside the closed chamber (19). According to the testing device, combustible gas explosion tests in a full-scale building under various working conditions can be achieved smoothly, and combustible gas explosion pressure parameters are provided for scientific computation and engineering application.

Description

technical field [0001] The invention belongs to the technical field of gas explosion mechanics test and research equipment, in particular to a test device capable of performing combustible gas explosions in various working conditions inside a full-scale building. Background technique [0002] The explosion of combustible gas in the explosion-venting space is an important content of the research on the hazard of combustible gas explosion. Due to the danger, destructiveness, high cost, and difficulty of testing in large-scale full-scale gas explosion tests, laboratory-scale small-scale scaled-down gas explosion tests are often carried out in actual research to study the spatiotemporal evolution of combustible gas explosions. As people's demand for life safety becomes more and more urgent, the research on the explosion of combustible gas in the explosion-venting space becomes more and more important. [0003] Due to the long-term needs of production and management safety in th...
