Ignition energy variable completely-transparent pipeline gas explosion experiment platform and method

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.), ...

AI Technical Summary

Problems solved by technology

[0003] At present, for gas explosion reactions, the explosion test chambers are mostly spherical, cylindrical, tubular and square; the materials are mostly fully enclosed stainless steel, plexiglass, semi-quartz tubes or small transparent windows, which are not conducive to observing and recording experimental phenomena; The research object is gas, liquid, dust or mixed type (such as: gas + solid); the pressure relief position is top or bottom pressure relief; for the experimental research content, most of the existing experimental equipment is simply to study the explosion limit of combustible gas, or Study the influence of one or two factors such as initial temperature, pressure, ignition energy, inert gas, area and number of obstacles in the pipeline on the explosion limit
