Embodiment Construction

[0047] Refer to attached Figure 1-11 , The size effect test system of gas explosion characteristics includes gas distribution device, ignition device, explosive device, data acquisition and processing device and high-speed digital camera.

[0048] The gas distribution device includes a combustible gas source, a gas distribution gas source and a gas distribution tank. The input ends of the gas distribution tank are respectively connected to the combustible gas source and the gas distribution gas source, and the other output of the gas distribution tank is connected to the explosive device. The input ports are connected.

[0049] The ignition device includes an igniter installed on the explosive device, and the igniter adopts electric spark to ignite. Depending on the installation position of the igniter, ignition at different positions can be realized; according to the depth of entering the container, two types of ignition can be realized: wall ignition and center ignition of...
