Abstract
The invention discloses a gas real-time monitoring and absorption device which comprises a gas density detector, a data acquisition unit, a data processor, a signal amplifier, a single-chip microcomputer, a signal transmitter, an electric pump, a nozzle and the like. The input end of the data acquisition unit is connected with the output end of the gas density detector, the input end of the data processor is connected with the output end of the data acquisition unit, the input end of the signal amplifier is connected with the output end of the data processor, the input end of the single-chip microcomputer and the input end of the signal transmitter are respectively connected with the output end of the signal amplifier, the input end of the electric pump is connected with the output end of the single-chip microcomputer, and the input end of the nozzle is connected with the output end of the electric pump. When a gas emission accident occurs in a tunnel, the single-chip microcomputer controls the electric pump to work according to the intensity of signals received from the signal amplifier, a large number of atomized surface active agents are sprayed into the tunnel through the nozzle, and high-density gas in the tunnel is absorbed.
Description
Technical field:
The present invention relates to mine gas and administer field, be specifically related to a kind of gas Real-Time Monitoring and absorption plant.
Background technology:
Gas is one of key factor affecting safety of coal mines all the time, and the particularly serious gas explosion accident that the whole nation occurs especially is in recent years continuous, and the life security to the people and national wealth have caused huge loss.Reduce tunnel and face gas concentration so must adopt an effective measure.At present in coal mining activity, normally adopt the mode that mine is ventilated, gas is discharged outside mine, to dilute the concentration that reduces gas.When but the content of the gas gathering when work plane is higher, only depend on the mode of ventilation to discharge gas, have technically a lot of difficulty, if ventilate not in time, when gas density height is to a certain extent time, be easy to occur gas accident, cause casualties and property loss.
Summary of the invention:
The object of the invention is the defect for prior art, a kind of gas Real-Time Monitoring and absorption plant are provided.
