Embodiment Construction

[0024] The invention provides a combustible gas explosion test device for testing narrow and long confined spaces under multi-factor conditions, which includes an ignition device, a pressure-resistant airtight container, a combustible gas tank, an air compressor and a PLC control assembly device.

[0025] Both the combustible gas tank and the air compressor are installed at the front end of the pressure-resistant airtight container, and are connected to the pressure-resistant airtight container through a pipeline. An air compressor valve and a combustible gas tank control valve are installed on the pipeline to realize the pressure-resistant airtight container. Gas distribution inside the pipeline in a pressure-tight container.

[0026] The pressure-resistant airtight container is composed of multi-section stainless steel round pipes fixed and sealed with bolts and rubber gaskets.

[0027] The quantity of the stainless steel circular tubes can be increased or decreased as requi...

Abstract

The invention provides a testing apparatus for burning and explosion of combustible gas in narrow, long and restricted space under the condition of multiple factors. The testing apparatus comprises an ignition device, a pressure-resistant enclosed container, a combustible gas tank, an air compressor and a PLC control assembly unit. The testing apparatus researches on the explosion characteristics and reaction process mechanisms of a variety of combustible gases under different conditions through barrier setting, gas distribution, ignition, measurement, acquisition and integration of an analysis system and provides technical reference for pipeline arrangement, explosion suppression design and safety evaluation.

Description

technical field [0001] The invention relates to the technical field of safety science and engineering experiment equipment, in particular to a combustible gas explosion test device in a long and narrow space. Background technique [0002] Under the ground, the urban culverts and oil and gas pipelines are intricately laid, and intersections are inevitable. Once leakage occurs at these intersections, the volatilized oil and gas will mix with the air in the culvert and accumulate in a relatively closed narrow space in the culvert. Rapid deflagration, even detonation, will cause extremely serious damage and cause great loss of personal and property safety. Sinopec's "11.22" oil pipeline leakage explosion was a typical oil and gas explosion accident in a narrow and long space, which caused a bad social impact. It is of great significance to construct a typical explosion test device in a narrow and long confined space to study the characteristics of combustion and explosion of co...
