Embodiment 1

[0022] The invention provides an experimental device for measuring the impact of gas explosion with initial pressure, such as figure 1 As shown, it includes: a pressure-resistant and airtight wall 1 composed of four stainless steel plates fixed and sealed by bolts and rubber gaskets, a transparent observation window 13 is arranged on the wall near the flame acceleration device 11 and the object 12 to be measured, and the close to the device There is a pressure relief port 2 at the rear of the right side of the wall. Once the pressure is over, the explosion-proof disk on the pressure relief port 2 will automatically rupture to achieve safe pressure relief. There is a pipeline at the end of the container 1 that is connected to the vacuum pump 16 through the stop valve 15. The container 1 A pressure gauge 21 is arranged on the wall of the container to monitor the initial pressure of the combustible gas in the container; the oxygen storage tank 6 is connected to one of the air inle...

Abstract

The invention relates to an experiment apparatus for measuring influence of gas explosion to a structure, and mainly solves the problem that multiple overpressure values cannot be generated in a same container in the prior art. According to the experiment apparatus for measuring influence of gas explosion to the structure, one end of an anti-pressure sealed container (1) is provided with at least two air inlets, an oxygen storage tank (6) is connected with one of the air inlets via an oxygen metering instrument (8) and an oxygen booster pump (20), an explosion gas storage tank (7) is connected with the other air inlet via an explosion gas metering instrument (17) and an explosion gas booster pump (18), and the container (1) is inside successively provided with an ignition device (5), a flame acceleration device (11), a pressure sensor (4), and a to-be measured object (12) fixedly disposed in the container (1) along the gas flowing direction. The above technical scheme relatively well solves the above problems, and the experiment apparatus is applicable to experiment for measuring influence of pressurized-gas explosion to a structure.

Description

technical field [0001] The invention relates to an experimental device for measuring the influence of a gas explosion on a structure. Background technique [0002] Combustion and explosion accidents of pressurized gas in containers of petrochemical enterprises occur frequently, and often cause extremely serious damage to devices, equipment and internal structures. To study and test the damage of pressurized gas explosions to different structures requires corresponding experimental devices. "Combustion Science Technology" magazine (1987, 52, 121-137 pages) has introduced a kind of explosion experiment device that adopts single-row tubular obstacle to increase flame velocity and overpressure, but this device size is too large (30 * 20 * 10m ), it is not suitable to use this device for small-scale experimental testing, and the arrangement space of obstacles is too large to meet the requirements of producing a lower gas explosion overpressure to a higher gas explosion overpressu...
