Abstract
The invention discloses an underground lifesaving facility for a coal mine and particularly relates to a device for absorbing carbon monoxide and carbon dioxide for an underground lifesaving cabin and a refuge chamber. The device disclosed by the invention comprises an absorption barrel, an air power device and an air outlet, wherein an absorbent and a filter screen are arranged in the absorption barrel; the air power device is a manual and pneumatic device; the absorption barrel is respectively connected with a linkage valve, a manual pump and a pneumatic pump through a tee joint; and a rotameter and a tester are arranged on a connecting pipe of the absorption barrel. The device disclosed by the invention absorbs carbon monoxide and carbon dioxide in a pneumatic mode and a manual mode, purifies the environment in the refuge chamber, and reduces the carbon dioxide content to 0.5% or below and the carbon monoxide content to 24ppm or below, thereby being suitable for the lifesaving of miners and prolonging the life. The device for absorbing carbon monoxide and carbon dioxide plays an important role on the safety protection of the lifesaving cabin and the refuge chamber, thereby laying an important foundation for the field of life safety rescue of underground miners in a coal mine.
Description
One, technical field
The invention belongs to lifesaving appliance under the coal mine, be specifically related to carbon monoxide, absorption unit of dioxide carbon that down-hole lifesaving booth and refuge chamber are used.
Two, background technology
All be provided with lifesaving booth and refuge chamber in the China's coal-mine down-hole, in case the accidents such as gas or dust explosion occur, distress personnel will be kept with lifesaving booth and refuge chamber the existence of certain hour.And distress personnel is realized eupnea at survival processes, must absorb the toxic and harmfuls such as carbon dioxide that (filtration) carbon monoxide and human body respiration discharge, so, all dispose the absorption plant of carbon monoxide and carbon dioxide at down-hole lifesaving booth and refuge chamber.The carbon monoxide that lifesaving booth and refuge chamber are used under the existing well and the absorption plant of carbon dioxide all have power initiation, and many contact point of power source just increase suspicion of danger hidden danger under the coal mine, reduce on the contrary one with regard to how a safety.And in case have an accident, down-hole power is cut off, and makes absorption plant be difficult to start.The laws and regulations in the fields such as the present colliery of China, fire-fighting are quite strict to specification requirement and the safety precaution regulation of rescue rescue, the product that relates to coal mine down-hole body safety is guaranteed should be able to work after the outage, guarantee security performance and the reliability of this series products.When guaranteeing that product is safe and reliable and meet the requirement of relevant criterion clause.
Three, summary of the invention
The purpose of this invention is to provide non-transformer carbon monoxide, absorption unit of dioxide carbon that a kind of down-hole lifesaving booth and refuge chamber are used.
The technical solution used in the present invention is: carbon monoxide, absorption unit of dioxide carbon comprise absorbing barrel, air generation plants and exhaust outlet, absorbent and screen pack are arranged in absorbing barrel, air generation plants of the present invention is pneumatic for manually adding, absorbing barrel connects respectively linked valve, manual pump and air driven pump by threeway, at the tube connector of absorbing barrel spinner flowmeter and tester is arranged.
The present invention absorbs carbon monoxide or carbon dioxide by pneumatic and manual dual mode, purify the environment in the refuge chamber, reduce carbon dioxide below 0.5%, carbon monoxide is below 24ppm, take refuge to adapt to the miner, extending life, this plays significant role to survival capsule and refuge chamber security protection, for having established important foundation in underground coal miners life security rescue rescue field.
Four, description of drawings
Accompanying drawing is structural representation of the present invention.
Five, the specific embodiment
In drier 2, filtration, cooling net 3, absorbent 4, free flow spiral formula passage is arranged, make air contact medicament area large; The net 3 that filters, lowers the temperature adopts wire nettings, and the effect of control temperature is more outstanding.
The present invention both can be used for absorbing carbon monoxide, also can be used for absorbing carbon dioxide, and when absorbing carbon monoxide, absorbent 4 is absorbents of carbon monoxide, comprises manganese dioxide (MnO
2), cupric oxide (CuO) and silver oxide (Ag
2O); Tester 8 is carbon-monoxide analyzer.During work, at first device for opening loam cake 1, open by pneumatic 5kPa and the manual linked valve 9 that consists of of 10N, restart manual pump 10 or air driven pump 17, environmental air begins in the direct access to plant, air-flow absorbs airborne moisture (humidity absorbability 20%RH is following) by drier 2, carry out carbon monoxide by filter, lower the temperature net 3 and manganese dioxide, cupric oxide and silver oxide absorbent 4 again and absorb (filtration), absorbability is below 1%CO, and the net 3 that filters, lowers the temperature plays the effect of regulating resistance and cooling.Spinner flowmeter 7, carbon-monoxide analyzer 8, the carbonomonoxide concentration after having absorbed according to the flow follow-on test of setting is simultaneously with the flow of reverse valve 11, exhaust outlet 14, spinner flowmeter 12 adjusting single unit systems, resistance, temperature etc.
When absorbing carbon dioxide, absorbent 4 is carbon-dioxide absorbent, comprises calcium hydroxide, lithium hydroxide or molecular sieve; Thimble 5 is arranged before screen pack 6, the absorbent packing of thin-film package can be punctured; Tester 8 is the carbon dioxide tester.Device for opening loam cake 1 during use, restart source of the gas, open linked valve 9 and manual pump 10(or air driven pump 17), environmental air begins in the direct access to plant, carry out carbon dioxide absorption (filtration) by absorbents 4 such as drier 2, filtration, cooling net 3, calcium hydroxide, lithium hydroxide or molecular sieves, spinner flowmeter 7,12, carbon dioxide tester 8, gas concentration lwevel after having absorbed according to the flow rate test of setting is simultaneously with the flow of reverse valve 11, exhaust outlet 14, spinner flowmeter 12 adjusting single unit systems, resistance, temperature etc.
Continuous operation of the present invention is stable, changes primary drying agent and absorbent in 6 hours.Absorb (filtration) precision and highly sensitive, 10 years service time of single unit system.
