Technical field
The utility model relates to a kind of infrared gas analyzer, relates in particular to infrared gas analyzer under a kind of coal mine.
Background technology
The coal in China reserves are abundant, and coal all is the topmost primary energy of China all the time.Yet coal mining often is accompanied by excessive risk, and coal mining accident constantly takes place, and has caused serious casualties, economy and politics loss.How to strengthen the mine disaster preventing and controlling, how correctly to handle the relation of safety and production, safety and benefit, fulfil the coal mine safety monitoring function how accurately, in real time, fast, guarantee the efficient running of rescue and relief work, safety rescue, become the most important thing of coal mine working.Facts have proved that quickly and accurately mine gas being tested and the data that test draws are made analysis and judgement is very important to reducing mine fire and gas explosion.The coal mine gas check and analysis are the essential bases that ensure mine safety, are the fundamental basis of colliery disaster prevention, improvement and disaster relief decision-making.
Lay the place difference according to equipment, mine fire beam tube monitoring system is divided into ground type and down-hole type.The ground type to ground, adopts the Ground analysis instrumental analysis by " beam tube " suction downhole gas sample, carries out continuous monitoring; But because its exhaust pipe is long, it is relatively poor that the gas sample is analyzed real-time, and be easy to the accuracy of factor affecting gas analyses such as because of the pipeline windage excessive or pipeline principal fault, thereby influence monitoring accuracy, and material, construction and maintenance cost are all very high.The down-hole type is by being placed on the monitoring equipment of down-hole, the parameter of required monitoring is carried out field monitoring sampling, analyzing and processing, thereby avoid the monitoring analysis error brought because of exhaust pipe is long as far as possible, improve the real-time and the accuracy of monitoring, all saved cost greatly in each link simultaneously.High-performance, accurate gas analyzer are the colliery mine gas bases of monitoring in real time.Therefore, need infrared gas analyzer under a kind of like this coal mine: as the core component of colliery mine gas monitoring device, to gas sample lasting, the on-line analysis fast in 24 hours of gathering, to realize the real-time monitoring of colliery mine gas.
The utility model content
The purpose of this utility model provides infrared gas analyzer under a kind of coal mine, and its analysis precision and validity are better than the electric chemical formula and the catalytic sensor of traditional supervisory system greatly; The series connection of each analytic unit, but realize single injected sampling just polycomponent analyse; Analyze fast, preserved pipeline data in 1-2 minute, to avoid the deficiency of the several data of traditional analysis method each sampled point every day.
The purpose of this utility model is to be achieved through the following technical solutions:
Infrared gas analyzer under a kind of coal mine comprises the analyser main body, and a side of described analyser main body is provided with air intake opening and gas outlet, and described analyser main body is provided with CO
