Beam tube monitoring system for gases in coal mine, all in the presence of one it is universal the problem of, that is, equipment is very accurate in laboratory test data,
Colliery actual industrial field application for a period of time after, the data deviation that analytical equipment is analyzed is increasing, when serious even
It can not use, to find out its cause, problem mainly goes out colliery scene dust is high, high humidity and Code in Hazardous Special Locations oxygen content are too low.Wherein
Dust, high humidity are the natural enemies for the equipment that gas-chromatography and all kinds of use optical principles are analyzed, and dust can cause analytical equipment
Pipeline blockage, correlation analysis device is stained, and high humility gas can cause condensed water is hazed and produced inside analytical equipment, and the lighter leads
Analysis result is caused to have different, severe one can cause equipment to be damaged.Dust and high humidity equally influence catalysis burning, electrochemistry alanysis to set
It is standby, the too low main influence catalysis burning alanysis equipment of oxygen content.
Because analysis result caused by beam tube monitoring system for gases in coal mine analytical equipment is untrue, wrong report is gently then produced, is drawn
Rise coal mining enterprise start mutually should emergency preplan, cause the waste in terms of business manpower, material resources, financial resources, it is heavy then have and warn not
Report, can cause security incident, and beam tube monitoring system for gases in coal mine gas pretreatment dress is badly in need of in colliery in order to ensure safety in production
Put, be that coal mining enterprise escorts to improve beam tube monitoring system for gases in coal mine, prevent the generation of fire class accident.
Current beam tube monitoring system for gases in coal mine is increased in beam tube line to the universal processing method of dust and high humidity
Water filter realizes dust-filtering, and high humidity gas natural condensation water is collected, hand-actuated.Increase medicine before analytical equipment to carry out
Dedusting, dehumidifying, need periodic replacement, it is impossible to continuous monitoring.
