Dust explosion testing device

Abstract

The invention discloses a dust explosion testing device. The dust explosion testing device comprises a quartz tube, a dust producing chamber connected with the top tube orifice of one vertical tube section of the quartz tube, a dust producing fan fixed to the dust producing chamber and provided with blades extending into the dust producing chamber, a sparking electrode jack formed in the quartz tube, a sparking electrode inserted into the sparking electrode jack, a sparking control system connected with the sparking electrode, an automatic bilaterally-opened door arranged between the top tube orifice of the vertical tube section and the dust producing chamber, and an automatic door control system controlling opening and closing of the automatic bilaterally-opened door, wherein the quartz tube is of a U-shaped structure and is composed of two vertical tube sections and a horizontal tube section connected at the bottoms of the two vertical tube sections. The dust explosion testing device is used for testing dust explosion and has the advantages of being better in parallel testing accuracy, convenient to clean, capable of observing the propagation situation of dust explosion pressure waves in a limited pipeline and safe in use.

Description

technical field [0001] The invention relates to a dust explosion test device. Background technique [0002] Under the power provided by the fan, the gas forms a vortex in the confined space. [0003] Dust explosion is a very serious accident with extremely high hazards. The Kunshan 8.2 dust explosion in 14 years has strengthened the urgency of people's research on dust explosion. The research on the minimum ignition energy of combustible dust is a basic research on dust explosion. Content, there are some defects in the existing test system at present, one is that in the parallel test, the consistency of the dust concentration in the ignition part of the ignition electrode cannot be guaranteed each time; the other is that after the test is completed, the dust is difficult to clean up. Research and improvement on this issue. [0004] The dust explosion can be considered to be formed by the following three steps: the first step is that the suspended or raised dust is rapidly ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a dust explosion test device with a new structure in order to solve the problems of poor accuracy, inconvenient cleaning and unsafe use of the dust explosion test device in the prior art, which is used for dust explosion In the test, it has the advantages of good parallel test accuracy, easy cleaning, observation of the propagation of dust explosion pressure waves in the restricted pipeline, and safe use.
