Embodiment Construction

[0033] The portable gas monitoring system of the present invention is composed of two parts, hardware and software. The present invention takes the portable monitor applied to coal spontaneous combustion and fire disaster gas in the mine as an example, and further describes the embodiment of the present invention in conjunction with the accompanying drawings.

[0034] 1. Hardware part

[0035] The hardware part of the portable mine gas monitoring system is as follows: figure 1 As shown, it consists of gas sampler, air intake dedusting and drying device, temperature and air pressure monitoring equipment, Fourier transform infrared spectrometer, data transmission line, battery, explosion-proof microcomputer, and for wireless transmission detection device, there is also wireless sending and receiving equipment.

[0036] The gas sampler is an explosion-proof modified air pump powered by a battery, which is connected to the gas chamber of the Fourier infrared spectrometer (also can...

Abstract

The invention discloses a portable multi-component mixed gas monitoring system. The portable multi-component mixed gas monitoring system comprises a gas sampler, a sample gas processing device, a gas pressure and temperature monitoring system, a portable computer, a portable infrared spectrometer and a storage battery. According to the portable multi-component mixed gas monitoring system, a gas to be analyzed is absorbed into the sample gas processing device through the gas sampler by utilizing infrared light absorption characteristics of a plurality of polar molecular gases, and enters a gas tank after being de-dusted and dried; the portable infrared spectrometer is used for analyzing the sample gas in the gas tank in real time, and meanwhile monitoring gas pressure and temperature of the gas in the gas tank to compensate analyzed results, so that monitoring staff can accurately monitor the smoke gas in a monitored environment within the first time after carrying the system into a well, can directly perform corresponding research and judgment according to each indicator gas concentration in the analyzed results, and can perform corresponding pre-warning.

Description

technical field [0001] The invention belongs to the field of detection of multi-component mixed gas, relates to the field of patrol inspection of mine gas and waste gas discharge, and in particular relates to a portable multi-component mixed gas monitoring system. Background technique [0002] Many small enterprises in many developing countries, including my country, illegally discharge polluted waste water and waste gas seriously, and the production environment of some enterprises is seriously substandard, leading to many production safety problems such as explosions. Environmental protection units, safety production supervision units, and hope that safe production The units need to have instruments for patrol inspection. [0003] For example, my country is a country that consumes a lot of energy, and a large part of the energy demand is met by the mining of coal resources in my country. However, accidents occur frequently in the process of coal mining. According to statist...
