摘　　要：泡沫除尘技术有着很好的发展前景,在改善煤矿粉尘污染方面效果显著。泡沫试剂配方是影响泡沫除尘效率的重要影响因素之一,影响试剂配方的主要因素包括:表面活性剂溶液起泡性能、稳泡性能和对粉尘的润湿性能。基于此,本文提出通过改进的Ross-miles法配制一种新型泡沫除尘试剂配方,配方中的试剂能够发挥优良协同效应,稳定提高配方溶液综合性能,并分析配方中复配试剂与原试剂性能参数变化情况,阐述各试剂间的作用机理。首先,测试单一起泡剂溶液起泡性能和稳泡性能,优选出性能参数最高的单一起泡剂溶液对应浓度。其次,向优选出的起泡剂溶液中加入不同种类稳泡剂,测试复配溶液起泡性能和稳泡性能,挑选出配伍性最好的稳泡剂及其添加浓度,得到不同表面活性剂组合的复配溶液。最后向复配溶液中加入润湿剂,提高溶液的润湿性能。最后,找出发挥协同效应最好,综合性能最优的表面活性剂溶液,将其浓度配置组合确定为新型泡沫除尘试剂配方。研究结果显示:浓度0.7%的改性烷基糖苷+浓度0.1%的羧甲基纤维素钠+浓度0.1%的辛葵基葡糖苷配制出的表面活性剂溶液性能参数最优。由此得出,改性烷基糖苷:羧甲基纤维素钠:辛葵基葡糖苷按7∶1∶1的比例制备溶液,作为新型泡沫除尘试剂配方将有效提高泡沫除尘的效率。The foam dust suppression technique demonstrates considerable potential for development and exhibits a significant impact on ameliorating coal mine dust pollution.The foam agent formula serves as a pivotal element in determining the efficiency of foam dust suppression,with key factors influencing the formula encompassing the foaming capability of the surfactant solution,the stability of the foam,and the wetting action towards dust.On this basis,this paper introduces a novel foam dust suppression agent formula prepared by enhancing the Ross-Miles method.The agents within the formula are designed to exert superior synergistic effects,thereby enhancing the comprehensive performance stability of the solution.The manuscript further analyzes the alterations in the efficacy parameters of composite agents relative to the singular agents,delineating the interactive mechanisms underpinning their performance.Initially,the foaming capabilities and stability of the individual foaming agent solution are evaluated,with the concentration of the solution yielding the optimal performance parameters being identified.Subsequently,various stabilizing agents are integrated into the chosen foaming agent solution,and the foaming capabilities and stability of the resulting composite solution are evaluated to determine the optimal stabilizing agent and its precise concentration,aiming to obtain a compound solution with various surfactant combinations.Finally,a wetting agent is introduced into the compound solution to enhance its wetting properties.Eventually,the optimal surfactant solution with the most synergistic effect and comprehensive performance is identified,and the concentration combination is ascertained as the novel formula for foam dust suppression.The experimental findings indicate that the surfactant solution exhibiting optimal performance parameters is obtained through the blending of a modified alkyl glucoside at a concentration of 0.7%,carboxymethyl cellulose at a concentration of 0.1%,and sinkonium glucoside at a concentr
