Mining anti-explosion coal bunker gas automatic emission control device

Abstract

The invention discloses a mining anti-explosion coal bunker gas automatic emission control device and belongs to the technical field of coal bunker gas emission. A bunker gas automatic emission control system with high safety, good energy-saving effect and capability of real-timely adjusting fan ventilation quantity according to gas concentration in a coal bunker is provided. According to the technical scheme, the mining anti-explosion coal bunker gas automatic emission control device comprises a processor unit, a gas concentration collecting unit, a power supply unit, a fan operation state control unit, a fan operation state monitoring unit, a fan control device, a non-intrinsic electric device control unit and a non-intrinsic electric switch unit, signal output ends of the gas concentration collecting unit and the fan operation state monitoring unit are electrically connected with a signal input end of the processor unit, and a signal output end of the processor unit is electrically connected with signal input ends of the fan operation state control unit and the non-intrinsic electric device control unit. The mining anti-explosion coal bunker gas automatic emission control device is applied to the field of coal mines.

Description

technical field [0001] The invention relates to an automatic gas discharge control device for mine explosion-proof coal bunkers, which belongs to the technical field of gas discharge from coal bunkers. Background technique [0002] Generally, due to the strong adhesion of gas to coal, when coal is transported from underground to underground coal bunkers or ground coal bunkers, a large amount of gas will be brought into the coal bunker. After the gas is separated from the coal, it is easy to accumulate in the coal bunker , cause the gas to exceed the limit, and when the concentration is too high, it will cause suffocation or even death, and may cause a gas explosion, which will bring safety hazards to the safe production of the mine and cause serious economic losses. Therefore, gas disasters have become a threat to mine safety. , An important factor restricting the development of mines. [0003] In order to reduce the gas concentration in the coal bunker and solve the proble...
