摘　　要：针对临涣选煤厂煤泥浮选起泡剂气味大、对环境污染严重、影响工人健康等问题,结合该选煤厂多煤种,且煤质变化大的实际情况,研发出了一种由戊醇(C_(5)H_(12)O)和仲辛醇(C_(8)H_(18)O)合成的,无刺激性气味、低毒的新型混合醇起泡剂KD-1Q,并进行了KD-1Q两相泡沫性质试验、起泡剂对煤颗粒表面润湿热检测试验以及工业性试验。结果表明:KD-1Q具有一定的起泡能力和稳定性,对临涣选煤厂煤泥具有较强的矿化效果,相对于其他厂家生产的烷基醇酰胺环保起泡剂每小时每吨节约药剂成本0.377元。There were many problems in Linhuan Coal Preparation Plant,including strong smell of slime flotation flother,environmental pollution and impact on workers'health.In addition,coal types and coal quality vary in the plant.Therefore,a new mixed alcohol flother KD-1Q was developed,which was synthesized from amyl alcohol(C_(5)H_(12)O)and octanol(C_(8)H_(18)O),with no pungent smell and low toxicity.The property test of KD-1Q two-phase foam,the wetting and heat test of coal particle surface by the flother,and the industrial test were carried out.The results show that KD-1Q presents foaming ability,stability,and stronger mineralization effect on coal slime.Compared with alkyl alcoholamide flothers produced by other manufacturers,the flother in Linhuan Plant can save the cost by 0.377 yuan/ton per hour.
