摘　　要：为减少进入煤泥水系统的煤泥量,简化煤泥水处理系统,提高产品发热量,提高企业的经济效益。采用增加末煤干法脱粉工艺的方法对海湾选煤厂进行改造。通过比较分析可知,增加末煤干法脱粉工艺可预先脱除原生煤泥,减少煤泥入水量,降低煤泥处理系统负荷,简化煤泥处理工艺,降低煤泥处理费用,同时旁路煤泥可作为产品掺入末煤产品,企业年销售收入增加829.22万元,具有较高的经济效益。In order to decrease slime content,lower handing capacity of slime treatment system,improve products calorific value and eco-nomic benefits,the original process of Haiwan coal preparation plant was transformed by adding fine coal dry screening process. The results showed that,the newly installed process could remove primary slime in advance,so less slime leaked into circulating water. The slime treat-ment process was simplified and the handing expense was decreased. The slime in the bypass could be mixed in fine coal. The plant in-creased sales revenue by RMB 8. 2922×106 .
