Embodiment Construction

[0026] The following implementations are used to illustrate the present invention, but not to limit the scope of the present invention.

[0027] figure 1 It is a schematic diagram of a variable ignition energy fully transparent pipeline gas explosion experiment platform of the present invention. The variable ignition energy fully transparent pipeline gas explosion experiment platform of the present invention includes a quartz tube 1, a data acquisition instrument 2, an ignition control box 3, a circulation pump 4, a vacuum gauge 5, a pressure gauge 6, a vacuum pump 7, an air valve 8, a pressure relief Valve 9, gas valve 10, two pressure sensors 11 and computer 12. Quartz tube 1 is a fully transparent quartz tube with a length of 1.5 meters, an inner diameter of 100 mm, an outer diameter of 115 mm, and a volume of 11.8 L. The quartz tube 1 is placed vertically, and the top and bottom ends are flange-connected with the fixing device. On the top flange, a pressure relief valve...

Abstract

The invention relates to the field of gas explosion safety engineering and in particular relates to an ignition energy variable completely-transparent pipeline gas explosion experiment platform and method. The experiment platform comprises an experiment pipeline, a vacuum meter, a pressure meter, a vacuum pump, an air valve, a circulation pump, a gas valve, two pressure sensors, an ignition control box, a data acquisition instrument and a computer, wherein the experiment pipeline is a completely transparent quartz pipe. The experiment platform is capable of synchronously triggering acquisition and ignition in the completely transparent quartz pipe under the ignition energy variable condition, accurately measuring explosion pressure and recording the flame propagation condition, and is simple to operate, low in cost, convenient to mount, high in safety performance and easy to popularize.

Description

technical field [0001] The invention relates to the field of gas explosion safety engineering, in particular to a variable ignition energy fully transparent pipeline gas explosion experiment platform and an experiment method thereof. Background technique [0002] Gas explosion (including flammable liquid vapor explosion) is one of the main forms of explosion disasters in industrial production and living fields. With the vigorous development of the petrochemical industry and coal industry, the construction of a large number of gas storage facilities and the mining of major coal mines, the frequent occurrence of gas, oil tank and gas explosion accidents has attracted widespread attention from all over the world. In the past ten years, many experimental studies have been carried out on the explosion limit and explosion characteristics of a single flammable gas. But so far, there are relatively few studies on the explosion limit of mixed gases (such as gas, natural gas, etc.), ...
