Negative-pressure environment explosion protection product explosion-proof performance testing device and method

Abstract

The invention discloses a negative-pressure environment explosion protection product explosion-proof performance testing device and method, which relate to the technical field of dust explosion prevention. The negative-pressure environment explosion protection product explosion-proof performance testing device comprises a first pipeline, an explosion-proof flap valve, a second pipeline, an explosion bin, a third pipeline, a dust filtering part and a fan, wherein one end of the first pipeline is connected with an explosion-proof flap valve, the explosion-proof flap valve is connected with an explosion bin through a second pipeline, the explosion bin is connected with one end of a dust filtering part through a third pipeline, the other end of the dust filtering part is connected with a fan,a detection part is arranged at the other end of the first pipeline, and a powder conveyor is arranged at the position, close to the explosion-proof flap valve, of the first pipeline. A two-way explosion-proof valve is arranged on the third pipeline, and an ignition head is arranged in the explosion bin. The dust explosion environment under the negative pressure ventilation and dust removal environment in the actual production condition can be simulated, the explosion-proof performance of an explosion protection product is tested, and the performance detection result of the explosion-proof product is more real and effective.

Description

technical field [0001] The invention relates to the technical field of dust explosion protection, in particular to an explosion-proof performance test device for negative pressure environment explosion protection products, and also relates to an explosion-proof performance test method. Background technique [0002] The research and development of dust explosion prevention and control devices in my country started late, especially the lack of corresponding explosion protection product inspection and testing systems to provide technical support, resulting in the research and development level of my country's explosion protection products being significantly lower than that of developed countries such as Europe and the United States, and dust explosion disasters still occur from time to time . At present, the negative pressure ventilation dust removal and explosion-proof system is widely used in enterprises involving metal dust, wood processing dust, medicinal material dust, ele...

AI Technical Summary

Problems solved by technology

At present, the negative pressure ventilation dust removal and explosion-proof system is widely used in enterprises involving metal dust, wood processing dust, medicinal material dust, electrostatic spraying dust, etc. However, there is no dust explosion protection for typical explosion protection products under negative pressure ventilation conditions at home and abroad. The performance inspection and detection system cannot effectively detect the explosion-proof and disaster-proof performance of explosion protection products, resulting in uneven explosion-proof performance of explosion protection products on the market, so that dust explosion disasters that have a greater impact on society still occur from time to time
