Abstract

The invention relates to a combustible gas explosion venting harm effect testing device and an analytical method. The device comprises a harm effect parameter collecting device, an explosion device and a data collecting device. Disadvantages of shortages of existing combustible gas explosion venting harm effect research devices and methods are overcome, the combustible gas explosion venting harm effect testing device is reasonable in design, convenient to operate and capable of measuring corresponding parameters of pressure at any position of an external space of a pressure container and jet flames after explosion venting of combustible gas comprehensively and accurately, and also the harm effect analytical method is built. The device and the method can be widely used in dangerousness analyses such as shock waves and jet flames of petrochemical industry production devices after explosion venting of the combustible gas under an actual working condition, and have remarkable effects on anti-explosion safety design, personnel protection and the like.

Description

technical field [0001] The present invention relates to a safety test device and analysis method, especially a test device and analysis method for the pressure and flame when the combustible gas explosion is vented and propagated outside the pressure vessel, in particular to a combustible gas vent Explosion damage effect test device and analysis method. Background technique [0002] With the rapid development of industrial modernization, the use of flammable gas and dust has become more and more extensive, and its explosion accidents have become more frequent, which has become an important form of industrial explosion accidents. Explosion venting can lead the high-pressure combusted and unburned gas inside industrial devices or pressure vessels to the external space, so that the internal pressure can be reduced rapidly, avoiding the occurrence of explosion accidents and property losses, and thus has become a widely used explosion-proof technical means . During the explosio...
