洗油是煤焦油的一个馏分,除作捕收作用外,还有起泡和调整的作用。而目前用洗油作煤泥浮选捕收剂在国内外尚未见报道,采用洗油作为煤泥浮选的捕收剂进行实验研究,用洗油对煤泥进行浮选,在最佳完善指标时精煤的产率为77.87%,精煤灰分为12.62%,灰分偏高。通过使用抑制剂、分散剂、分散剂和抑制剂结合使用的方法最终使精煤的灰分降到9.57%,此时精煤产率为67.32%。相对仅使用洗油和起泡剂灰分降低了3.05%,产率下降了10.55%。
Wash oil is a fraction of coal tar, except for catching purposes, there are bubbles and adjust the role. At present, scrub flotation collectors have not been reported at home and abroad. The study of scrubbing flotation using scrubbing oil as flotation agent, Indicators, the yield of refined coal was 77.87%, fine coal ash was 12.62%, high ash content. The combined use of inhibitors, dispersants, dispersants and inhibitors eventually reduced the ash content of the clean coal to 9.57%, at which time the clean coal yield was 67.32%. Relatively using only wash oil and foaming agent ash decreased 3.05%, the yield decreased by 10.55%.
