Abstract

The invention discloses an oil-gas explosive critical parameter testing device. The oil-gas explosive critical parameter testing device comprises an explosion reaction pipe, an inert gas supply device, a vacuum pump, a gas analyzer and an ignition device. The invention provides the explosive critical parameter testing device with a high-energy ignition source, which is used for simulating an actual volatilization state of oil gas in an oil tank and uses the online gas analyzer to test an explosive critical parameter, aiming at the problems that the conventional explosive testing device is lack of guiding and practical values of detection data and the like. The oil-gas explosive critical parameter testing device uses a sealing pipeline with a cross section which has an area equivalent to an area between primary seal and secondary seal of the conventional oil storage tank with the volume of 100,000 cubic meters as an explosion reaction pipe; the oxygen concentration and an oil gas concentration of mixed gas inside the pipeline can be respectively controlled by introducing nitrogen and oil gas; an electric sparkle firing and igniting test is carried out; and the explosive strength of the mixed gas, and the oxygen concentration value and the oil gas concentration value before explosion can be tested, so that the upper limit and the lower limit of the oil gas explosions under different oxygen concentrations can be found out. Therefore, the safe section of the oil-gas mixed gas can be found out.

Description

technical field [0001] The invention relates to the technical field of explosion testing, in particular to a testing device and a testing method for testing oil gas concentration and oxygen concentration in the critical state of oil gas explosion. Background technique [0002] Oil tank is an important storage device for oil. Due to the flammability and explosiveness of oil and the limited space of oil tanks, oil tank accidents caused by oil and gas explosions have occurred frequently in recent years. The critical parameters of oil and gas explosions have a great impact on oil and gas explosions. Tank safety protection is of great significance. [0003] The basic condition for an oil and gas explosion is the existence of oil, gas and oxygen. Oil and gas refer to the gas generated from the volatilization or escape of oil, mainly gaseous hydrocarbons such as C1-C6. The specific components are related to the type of oil and the ambient temperature. . When the oil gas and air (...
