为降低煤矿空气中的甲烷浓度,基于増溶方式设计新型水基抑爆介质,在单一表面活性剂对甲烷增溶作用效果的基础上,选取单烷基醚磷酸酯钾(MAEPK)、脂肪酸酯聚氧乙烯醚(FMEE)和癸基葡萄糖苷(APG10)为复配原料,研究不同配比下,复配溶液对甲烷的增溶效果,并考察增溶后溶液释放甲烷规律。结果表明:甲烷的表观溶解度与表面活性剂浓度呈线性正相关;MAEPK-APG10和MAEPK-FMEE的最优增溶配比均为1:4;复配使APG10在1 h内甲烷释放率由原来的63.65%降低至50%以下,MAEPK-FMEE复配溶液的甲烷释放率仅为18.2%。
In order to reduce the concentration of methane in the air of coal mine, a new type of water-based suppressor was designed based on the solubilization mode. Based on the effect of single surfactant on the solubilization of methane, MAEPK, Ester polyoxyethylene ether (FMEE) and decyl glucoside (APG10) were used as raw materials to study the solubilization effect of complex solution on methane under different proportions, and the methane release was also investigated. The results showed that there was a linear positive correlation between the apparent solubility of methane and the surfactant concentration. The optimum solubilization ratio of MAEPK-APG10 and MAEPK-FMEE was 1: 4. The methane release rate of APG10 in 1 h was The original 63.65% to 50% below the MAEPK-FMEE complex solution methane release rate was only 18.2%.
