Embodiment 1

[0040] This embodiment provides a gas absorbent for reducing the gas concentration, which is used for spraying on the working face of the mine to absorb the gas whose concentration exceeds the standard. The gas absorbent is formed by mixing castor oil, surfactant and water in a certain proportion In the liquid organic combination solution, each material is calculated by weight percentage, wherein the amount of castor oil is 1-6% by weight percentage, the amount of surfactant is 8-19% by weight percentage, and the rest is water. Wherein, the surfactant includes: sodium lauryl sulfate, sodium oleate, alkylphenol polyoxyethylene ether (Triton x-100), Tween 80, castor oil polyoxyethylene ether (EL-20) of any kind.

[0041] When sodium lauryl sulfate is used as the surfactant in the above absorbent, its consumption is 14-19% by weight.

[0042] When the tensio-active agent in the above-mentioned absorbent adopts any one in alkylphenol polyoxyethylene ether (Triton x-100) or Tween ...

Embodiment 2

[0048] The gas absorbent for reducing the gas concentration provided in this example is specifically made by mixing castor oil, surfactant and water, and after mixing, an organic ordered assembly solution is formed, wherein the amount of castor oil is 3% by weight , Surfactant adopts sodium lauryl sulfate, and its consumption is 17% by weight percentage.

[0049] The gas absorbent in this embodiment, when the amount of castor oil is 3% by weight percentage (when the concentration of castor oil in the absorbent is 3%), and dodecane as surfactant When the consumption of sodium base sulfate is 17% by weight percentage (that is, when the concentration of sodium lauryl sulfate in the absorbent is 17%), the absorption liquid obtained after the absorbent of the composition absorbs methane carries out headspace gas chromatographic analysis , Figure 2-4 It is the gas chromatograms obtained after three headspace extraction gas chromatography analyzes after the absorbent absorbs methan...

Embodiment 3

[0051] The gas absorbent for reducing the gas concentration provided in this example is specifically formed by mixing castor oil, surfactant and water, and after mixing, an organic ordered assembly solution is formed, wherein the amount of castor oil is 2.65% by weight , Surfactant adopts sodium oleate, and its consumption is 8.85% by weight percentage.

[0052] Gas absorbent in the present embodiment, when the consumption of castor oil is 2.65% by weight percentage (when the concentration of castor oil in this absorbent is 2.65%) through testing, and as surfactant sodium oleate When the consumption is 8.85% by weight percent (i.e. when the concentration of sodium oleate in the absorbent is 8.85%), the absorption liquid obtained after the absorbent of the composition absorbs methane carries out headspace gas chromatography analysis, Figure 5-7 It is the gas chromatograms obtained after three headspace extraction gas chromatography analyzes after the absorbent absorbs methane ...

Abstract

The embodiment of the invention provides a gas absorbent for reducing gas concentration. The gas absorbent belongs to harmful gas absorbing materials of mines. The absorbent is liquid organic ordered combination solution which is formed by mixing the following materials by weight percentage: 1-6 percent castor oil, 8-19 percent surfactant and the rest of water. The castor oil in the absorbent increases the solubility in surfactant micelle, thereby increasing the volume of the surfactant micelle and leading a whole liquid system to form the ordered organic combination; the organic ordered combination provides an organic micro-environment, the micro-environment can increase the solubility of methane, lead the methane to be wrapped in the organic micro-environment, and the gas absorbent is sprayed on the working surface of a mine to achieve the purposes of absorbing gas with excessive concentration and eliminating the safety hidden troubles which can cause explosion.

Description

technical field [0001] The invention relates to a harmful gas absorbing material for coal mine safety production guarantee, in particular to a gas absorbing agent capable of effectively absorbing gas and reducing the gas concentration in the air. Background technique [0002] Gas prevention and control research mainly includes gas drainage technology, mine ventilation, gas explosion control and suppression materials, solidification technology to prevent gas outburst, gas hydration technology for gas control, coal seam water injection technology for gas prevention and control, and microbial gas control technology. The above method for preventing and controlling gas can prevent gas accumulation and gas outburst, but it has a certain time delay. When it is monitored that the gas concentration exceeds the standard, the production can only be stopped, and underground ventilation should be strengthened to reduce the gas concentration. Gas-absorbing materials can quickly absorb ga...
