Detailed Description
As shown in fig. 1-2, the utility model discloses a coal sample jar 1, filter jar 2 and gas analyzer, filter jar 2 detachably and install in coal sample jar 1 upper end, be equipped with zinc oxide granule 3 in filtering jar 2, the gas outlet department of filtering jar 2 is equipped with a jar body valve 4, the gas outlet of jar body valve 4 pass through rubber hose 5 with gas analyzer's air inlet 14 is connected, be equipped with manometer 6, stagnant water valve 7, gasbag 8 and ending valve 9 on rubber hose 5's the pipeline in proper order, gasbag 8 is transparent compressible gasbag, and blue litmus test paper 10 has been placed to the bottom in the gasbag 8.
It should be noted that the air bag 8 can be contracted to ensure the balance of air pressure in the pipeline, the blue litmus test paper 10 can detect water flowing back in the gas analyzer, the shape of the blue litmus test paper 10 is matched with the cambered surface at the bottom of the air bag 8, and further, when the water amount in the air bag 8 is small, the blue litmus test paper 10 can also detect the water amount; the manometer 6 is used for monitoring the pressure of the gas that produces in the coal sample jar 1, can master the hydrogen sulfide through the change of observing pressure and by the absorptive condition of zinc oxide granule 3, filter the zinc oxide granule 3 in the jar 2 and can react with hydrogen sulfide, generate the zinc sulfide solid to absorb the hydrogen sulfide in the gas and filter, and then guaranteed the accuracy of gas content survey.
The utility model discloses a during device survey gas content, the desorption of gas adsorbs is a dynamic process, and the coal sample does not have more spaces after the gas desorption is partly when coal sample jar 1 is sealed, consequently on the gas that has desorbed can adsorb the coal sample again, reaches desorption absorbent dynamic balance, and the change that also is manometer 6 is for lasting rising then remain stable. The reaction process of the hydrogen sulfide lags behind the process of gas desorption, but because the relative molecular mass of the hydrogen sulfide is greater than that of the gas, the pressure gauge 6 can be slightly lowered after the hydrogen sulfide reacts with the zinc oxide particles 3, but because the gas is a desorption and adsorption balancing process, the pressure difference generated after the hydrogen sulfide reacts can be filled with the desorbed gas again. In general, the pressure gauge 6 changes to start to assume a rising state, falls back with a small amplitude after stabilization, and then remains unchanged with a small amplitude. When the reading of the pressure gauge 6 is unchanged, the reaction between the hydrogen sulfide in the coal sample and the zinc oxide absorbent is complete, and the influence of the hydrogen sulfide on the gas content measurement result is better eliminated.
