Problems solved by technology

[0009] The invention realizes the positive pressure delivery of gas samples through the first pressurization pump and the second pressurization pump, realizes the long-distance fast delivery of gas in the bundle tube monitoring system, and solves the problem of slow gas movement caused by traditional negative pressure pumping Even if there is a slight leakage in some parts of the pipeline, no outside air will be sucked into the pipeline, thus avoiding the mixed pollution of gases and ensuring the monitoring results

Abstract

The invention belongs to the field of beam tube monitoring, and particularly relates to a positive-pressure sampling pump station for a sampling system. The positive-pressure sampling pump station comprises an A-path positive-pressure sampling device, a B-path positive-pressure sampling device and a gas branching switching device. By adopting the positive-pressure sampling pump station, the A-path positive-pressure sampling device and the B-path positive-pressure sampling device can perform independent conveying work respectively, the A-path positive-pressure sampling device and the B-path positive-pressure sampling device can be combined into one path to be used for conveying, and switching between the two conveying ways is mainly completed by the gas branching switching device. The positive-pressure sampling pump station can meet the actual working condition requirement under a coal mine, the conveying ways are configured flexibly, and sampling work of a coal mine safe beam tube monitoring system can be performed conveniently.

Description

Technical field [0001] The invention relates to a positive pressure sampling pump station for a sampling system, belonging to the field of bundle tube monitoring. Background technique [0002] In recent years, coal mine safety beam tube monitoring systems have begun to gain more and more popularity and applications in coal mines. [0003] The mine safety beam tube monitoring system uses the beam tube to extract and summarize the air from all parts of the mine to the designated location, and then analyzes the air samples collected by the beam tube with the aid of a chromatographic monitoring device to realize the detection of CO, CO 2 , CH 4 , C 2 H 4 , C 2 H 6 , O 2 , N 2 For the online monitoring of gas content, the analysis results can be automatically stored in the database while providing data in real-time monitoring reports and analytical daily reports, so as to analyze the change trend of a certain gas content in the future, thus achieving Early prediction of spontaneous comb...
