Description
Technical field
The present invention relates to field of gas detection, particularly a kind of Portable detection instrument for multiple gases.
Background technology
China is coal production maximum in the world and country of consumption, is also that a few take coal as one of country of main energy sources in the world.In progress of coal mining, have multiple harmful gas to coexist in coal seam, as CH4, CO, SO2, NH3 etc., latter two gas content is few, and with water-soluble, can process through water spray; But CH4, CO content is many, and is insoluble in water, belongs to flammable explosive gas again, and gas density reaches explosion limits, have enough oxygen and uniform temperature ignite burning things which may cause a fire disaster time, will gas explosion be there is, bring hidden danger to the life security of coal mining person.For protecting the health and lives safety of workman, the gaseous environment performed under mine in strict accordance with safety regulations in coal mine detects, and develops the many gas detecting instruments of a kind of Portable mining particularly important to the gaseous environment detected under mine.
Under mine, gaseous environment detects and mainly contains three classes: inflammable gas detection, toxic gas detection, oxygen detection, this gas detecting instrument can detect the gas that in three class gases, content is higher.Gas is the gas of a large amount of storage in coal seam, has the features such as inflammable and explosive, maximum to coal mining harm.Main harm shows as: the first, gas density is too high, and remarkable impact shows as anoxic, has difficulty in breathing, suffocates; The second, gassy seam blast, blast produces enormous impact ripple and thermal-flame, can destroy all; Three, Gas Outburst in coal; Four, a large amount of gas enters air from ventilation shaft, pollutant atmosphere.The general accounting example more than 90% of methane in gas, therefore the detection of methane CH4 is the main detected parameters of many gas detecting instruments.The gas that toxic gas is as higher in CO, CO2 content, excessive concentration can affect people and breathe, and is easy to cause death by suffocation.Oxygen O2 aloft content is very high, if lower than finite concentration, people can be allowed to breathe confusion, lose consciousness, even dead.
Support the Coal Industrial of one of the energy industry emphasis of China's rapid economic development, more huge to various sensor equipment quantity.China is maximum coal mine safety apparatus equipment state in the world, and be also one of important coal mine safety apparatus producing country, the various sensor equipment quantity in current China's emphasis colliery is in 1,000,000, and various safety monitoring equipment technology is all in improve.China is strengthening coal mining safety guarantee always, normative construction coal mine downhole safety hedging " six Iarge-scale system " in recent years, primary study has been carried out in Coalmine's Monitoring and Controlling System, along with popularizing of coal mine safety monitoring monitoring technique, each parameter detecting instrument application cumulative year after year within coal mines, but these Coal Mine Safety Monitoring Systems still have deficiency.Due to the multiplex carrier catalyst element of national security detection methane transducer, bring the problems such as gas detecting instrument job stability is not high, the life-span is short, adjustment is frequent, seriously govern the normal detection of concentration of mine methane, the replacing amount of methane detector is large.
