Compared with the prior art, the device has the advantages of beingreliable in safety, variable in combination of equipment and easy to disassemble and having the performances of gas observation and dust combustion and explosion; therefore, the device is suitable for various simulations, tests and demonstrations of gas and dust combustion and explosion performances.

Description

technical field [0001] The invention relates to a combustion and explosion simulation demonstration device, in particular to a gas or dust combustion and explosion performance test device using a supercapacitor. Background technique [0002] In recent years, gas and dust explosion accidents have occurred frequently, causing heavy casualties and property losses. According to the statistics of the causes of accidents, a large part of the accidents are caused by the hot surface of the motor under the contact condition of gas and dust, which reaches the minimum ignition temperature of gas or dust, resulting in combustion and explosion accidents. Relevant explosion-proof and fire-proof standards require that in explosion and combustion environments, the use of electrical equipment and facilities should be based on the lowest ignition temperature of gas or dust for the selection of explosion-proof motors to prevent excessive surface temperature of the motor from reaching the level...
