Embodiment
[0024] as attached figure 1 and image 3 Shown: a visual explosion suppression experimental device of square tube fire, explosives, dust and water mist, including an explosion tank 1 with openings on the front and rear sides, glass windows 2 are placed at the openings of the explosion tank 1, and each glass window 2 The front and rear sides are pressed against the sealing gasket 3 made of silica gel. With the help of the sealing gasket 3, the impact wave of the glass window 2 can be buffered and unloaded during the experiment, prolonging the life of the glass window 2, and also The sealing performance between the glass window 2 and the explosion tank 1 can be improved. The front and rear side walls of the explosion tank 1 are all threadedly connected with a tension bolt, and one end of the tension bolt is connected to a stainless steel pressing sheet 32 outside the two glass windows 2, and the sealing gasket 3 can be pressed against the stainless steel pressing sheet 32 b...

The invention discloses a visual square tube powder and explosive dust water mist explosion suppression experiment device, and particularly relates to the technical field of explosion experiment devices. The visual square tube powder and explosive dust water mist explosion suppression experiment device comprises an explosion tank with openings in the two sides, glass windows are detachably connected to the openings of the explosion tank, the explosion tank is communicated with a water inlet pipe, a water mist nozzle is arranged on the water inlet pipe, a powder spraying mechanism is arranged at the bottom of the explosion tank, and the powder spraying mechanism can spray dust into the explosion tank. A pressure relief ring in a circular truncated cone shape is arranged in the upper side of the explosion tank in a penetrating mode, an explosion disc is arranged in the pressure relief ring, a temperature sensor, a pressure sensor and an electrode are arranged in the explosion tank in a penetrating mode, a vacuumizing pipe is further communicated with the side wall of the explosion tank, a needle valve is installed on the vacuumizing pipe, and a negative pressure meter is further installed on the portion, between the needle valve and the explosion tank, of the vacuumizing pipe. According to the technical scheme, the problem that there is no appropriate water mist explosion suppression experimental device at present is solved, and the device can be used for research of water mist explosion suppression work.
Description
technical field [0001] The invention relates to the technical field of explosion experiment devices, in particular to a visual explosion suppression experiment device of square tube fire, explosive, dust and water mist. Background technique [0002] A large amount of suspended dust will be formed during the process of mixing, belt drying, packaging, etc. These suspended dusts will be more sensitive than the explosives themselves when stimulated by external energy, which is an important reason for the explosion of explosives. Explosion suppression technology can effectively contain such accidents in the initial stage, and can also effectively reduce the intensity of explosion shock waves. Existing explosion suppression technologies include water medium explosion suppression, inert gas explosion suppression and inert dust explosion suppression. However, inert gas and inert dust are not suitable for explosive suppression in principle, and the preferred medium for explosive supp...
