Abstract
The utility model particularly relates to an experiment table for natural coupling of gas and coal. The problems that according to an existing experiment device for coupling of the coal and the gas, due to an unreasonable mechanism, the experimental accuracy and safety performance are poor are solved. The experiment table for the natural coupling of the gas and the coal comprises a water storage pressure tank, a program temperature-controlled box, a temperature measurement meter and a gas chromatograph. A horizontally-arranged rope net is arranged inside the water storage pressure tank. A gas bag is arranged below the rope net. A funnel and a pressure meter are arranged above the water storage pressure tank, wherein the funnel is communicated with the water storage pressure tank, and the pressure meter is communicated with the gas bag. A control switch is arranged between the funnel and the water storage pressure tank, and a control switch is arranged between the pressure meter and the gas bag. A preheating tube and a coal sample tank are arranged inside the program temperature-controlled box. The coal sample tank is respectively communicated with the preheating tube, the gas chromatograph and the temperature measurement meter.

According to the experiment table for the natural coupling of the gas and the coal, the spontaneous combustion oxidation rule and the character influence rule of loose coal with different temperatures by the air leakage flow with different gas concentrations can be effectively researched.
Description
Technical field
The utility model relates to the underground mine use experimental provision, is specially a kind of gas and coal spontaneous coupling experiment platform.
Background technology
The coupled relation of gas and spontaneous combustion of coal is one of popular direction of current mine safety research.For the mine that has gas and spontaneous combustion of coal danger simultaneously, experimental study is very important means.
Not only comprise oxygen due in distinguished and admirable under coal mine, also contain methane, therefore containing the distinguished and admirable feature that more meets mine air of gas.In distinguished and admirable containing gas, the situation of change of the gas marker parameter produced after the coal heating, and methane is all unclear on the impact of coal under high temperature, this needs the support of related experiment equipment.
Coal ignitability's oxidation kinetics test macro can be for the research of the low-temperature oxidation process of coal.The method is distinguished and admirable under simulation well, dry air is continued to pass in the coal sample tank tank that coal is housed, and by temperature-controlled box temperature programme heating coal sample tank tank, makes coal body persistently overheating, the mixed gas characteristic parameter while simultaneously utilizing gas chromatograph to measure different coal temperature.Analyze and study the change procedure of these parameters, significant to deep understanding oxidation of coal process and mechanism.
The difficult point of coal and the research of gas coupling experiment is the design of experimental provision at present, and current experimental provision structure is reasonable not, and experimental precision and security performance are poor.
Summary of the invention
The utility model causes the poor problem of experimental precision and security performance in order to solve existing coal and gas coupling experiment device because mechanism is unreasonable, a kind of gas and coal spontaneous coupling experiment platform are provided.
The utility model is to adopt following technical scheme to realize: gas and coal spontaneous combustion coupling experiment platform, comprise the water-storage pressure tank, the temperature programmed control case, temperature measuring gauge and gas chromatograph, be provided with the netting of horizontal positioned in the water-storage pressure tank, the netting below is provided with airbag, water-storage pressure tank top is provided with the funnel communicated with it and the tensimeter be communicated with airbag, and between funnel and water-storage pressure tank, be provided with gauge tap between tensimeter and airbag, be provided with economizer bank and coal sample tank in the temperature programmed control case, the coal sample tank respectively with economizer bank, gas chromatograph and temperature measuring gauge are communicated with, be provided with the flow valve and the flowmeter that are communicated with both between economizer bank and tensimeter.
During operation, regulate the pressure in the water-storage pressure tank by add water in funnel, control the constant outflow of mixed gas in airbag, read force value by tensimeter, regulated and read flow value by flow valve and flowmeter, carry out subsequently preheating, the mixed gas after preheating is by the coal sample tank of different temperatures, the impact of analysis mixed gas on coal spontaneous combustion, overcome existing coal and gas coupling experiment device causes the poor problem of experimental precision and security performance because mechanism is unreasonable.
The utility model reasonable in design is reliable, guaranteeing under safe and reliable prerequisite, effectively studied the stream that leaks out of different gas densities to spontaneous combustion oxidation rule and the properties influence rule thereof of different temperatures loose coal, had advantages of simple in structure, easy to operate and cost is low.
