摘要:
The disclosure includes a gas analysis system comprising a control system. In some embodiments, the control system comprises a computer monitoring host, an underground coal mine gas circuit control box including an intrinsically safe PLC, a sampling pump electrically coupled to the remote power control, an explosion proof safety power box electrically coupled to the intrinsically safe optical fiber switch, and an intrinsically safe gas chromatograph electrically coupled to the intrinsically safe optical fiber switch and the flameproof and intrinsically safe power box. In some embodiments, the gas analysis system comprises a gas pipeline system having an instrument sequence tube coupled to the carrier gas output pressure sensor, the carrier gas proportional solenoid valve, the carrier gas path pressure sensor, a manual carrier gas pressure reducing valve, and a carrier gas storage.
