Abstract

The invention discloses a micro-chromatograph underwater beam tube monitoring system. The system comprises underground equipment and ground equipment. The ground equipment comprises a communication control device, and the underground equipment comprises a detection analysis portion and a beam tube sampling portion and is connected with the ground communication control device through a network. The detection analysis portion comprises a miniature gas chromatograph, a standard gas sample feeding control treatment device, a sample gas feeding and drying control treatment device and a carrier gas supply control device. The beam tube sampling portion comprises an intrinsic safety gating combined control device. The micro-chromatograph underwater beam tube monitoring system has advantages that online automatic high-precision real-time monitoring of gas contents of underground monitoring points is directly realized in an underground environment; unattended long-term reliable operation of the chromatograph is realized; network sharing of monitoring data results is realized; by adoption of an explosion-proof technique, operational reliability and normality in a flammable and combustible environment can be guaranteed, and adaptability to positive-pressure or negative-pressure sample gas collection modes is realized.

Description

technical field [0001] The invention belongs to the field of measurement, and in particular relates to a microchromatographic downhole bundle tube monitoring system directly used for gas component analysis in underground mines. Background technique [0002] At present, the main method of gas analysis in underground coal mines is sampling through manual or bundle pipe system underground, and monitoring and analyzing on the ground above the well. [0003] Manual measurement or sampling is adopted, and the measurement personnel directly measure at the determination site, or send the sample to the ground for analysis. The measurement location is flexible, but the frequency is low, and only normal gas samples can be measured, and hazardous environment measurement points cannot be measured. [0004] Use beam tube sampling, beam tube sampling + chromatographic analysis system (or online infrared analysis system). The location is convenient, the measurement is not affected by the ...
