Problems solved by technology

[0003] At present, domestic and foreign studies on the combustion and explosion characteristics of flammable gas clouds and flammable vapor clouds in confined spaces mainly use pipes of various sizes to simulate. Combustible gas cloud explosion in a confined space, and for a confined space with a small length-to-diameter ratio and large length, width and height dimensions, the results of the simulation study using pipes deviate greatly from the actual

Embodiment Construction

[0018] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0019] Such as Figure 1 to Figure 4 The shown device for simulating combustible cloud and steam cloud explosion in a confined space is the best embodiment of the present invention, including a simulated box, which is a cuboid structure, including a retractable frame, assembled and sealed in The panel section within the retractable frame. The panel portion includes an explosion-proof steel plate 9 arranged at the bottom of the cuboid structure and transparent panels 2 arranged at the other five sides of the cuboid. The explosion-proof steel plate 9 is a type 316 stainless steel plate. The transparent panel 2 is a tempered glass panel or a bulletproof glass ...

Abstract

The invention provides a device for simulating the explosion of combustible cloud and steam cloud in confined spaces. According to the device, a size-variable collapsible frame is designed; combustible gas cloud explosion process model experiments in confined spaces of different structures can be carried out; a liquid atomization module is additionally adopted; combustible vapor cloud explosion process model experiments in confined spaces of different structures can be also carried out; since various test sensors are installed in the installation holes of the device, and the five surfaces of the explosion device are all transparent, the combustion and explosion mechanisms of combustible gas cloud and steam cloud in the confined spaces of different structures can be researched with appropriate optical measurement technologies.

Description

technical field [0001] The invention relates to the technical field of explosion testing devices, in particular to a device for simulating the explosion of combustible clouds and steam clouds in a confined space. Background technique [0002] In industrial production, flammable and explosive gases and flammable liquids are widely used. Inflammable and explosive gases and flammable liquids leak during transportation, storage and use, forming flammable gas clouds and flammable vapor clouds. Especially in confined spaces, explosion accidents are more likely to occur, causing heavy property losses and casualties. The research on the explosion characteristics of combustible gas cloud and combustible vapor cloud in various types of confined spaces is of great significance to the prevention and control of combustible gas cloud and combustible vapor cloud explosion accidents. [0003] At present, domestic and foreign studies on the combustion and explosion characteristics of flamma...
