Experimental device for preventing and controlling dust explosion

Abstract

An embodiment of the invention discloses an experimental device for preventing and controlling dust explosion. The device comprises a main explosion tank body, a pressure sensor, a high-voltage discharge module, a flame detector, a first spray nozzle, a first pressure meter, a water storage tank, a first valve, a first group of bolts, a fixed baffle, an explosion venting material, a compressed aircylinder, a second pressure meter, a powder storage tank, a second valve, a second spray nozzle, a control system, a computer, a tank body and guide pipe connecting flange, an explosive-proof valve,an explosion venting guide pipe, a third valve, a vacuum pump, a compressed nitrogen cylinder, a fourth valve, an air hole, a blind flange, a fifth valve, a third pressure meter, an ignition rod, ignition electrodes and a second group of bolts. The device can show the principle of prevention and control core technologies for dust explosion such as explosion venting, explosion separation, explosionsuppression, inerting and the like, also shows the combined work principles of multiple technologies, is small in size, high in safety, low in cost and comprehensive in function, can better serve safety education training in the dust explosion field and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of dust explosion research, in particular to an experimental device for dust explosion prevention and control. Background technique [0002] Dust explosion prevention and control technology, mainly based on explosion venting, explosion isolation, explosion suppression, inertization, etc., is not only a necessary means for accident prevention and control of explosion-related dust enterprises, but also a professional course for undergraduates majoring in safety engineering in colleges and universities and the field of safety production. One of the core contents of various vocational education and training. [0003] At this stage, there are obvious disadvantages in the safety education and training of dust explosion in our country. On the one hand, the teaching of the basic knowledge of dust explosion is relatively common, and the education on related prevention and control technology and application level is ...

AI Technical Summary

Problems solved by technology

On the one hand, the teaching of the basic knowledge of dust explosion is relatively common, and the education on related prevention and control technology and application level is not comprehensive and in-depth; on the other hand, the existing education and training in the field of dust explosion mainly rely on traditional teaching methods such as classroom lectures It is difficult to vividly display the working principles of technical measures such as explosion venting, explosion isolation, explosion suppression, and inerting, which affects the teaching effect

However, limited by the constraints of site, time, safety, cost, etc., it is difficult to carry out targeted experimental teaching of dust explosion prevention and control with the help of large-scale test equipment.
