根据我国高硫煤的赋存特点和目前的技术基础，提出采用微细介质重介旋流器及细泥选择性絮凝组合工艺（简称ＦＨＭＣ－ＳＦ工艺）实现煤炭的深度脱硫降灰。采用ＦＨＭＣ－ＳＦ工艺较采用单一重介旋流器和重介旋流器—微泡浮选联合流程，无机硫脱除率可大幅度提高，分选下限明显降低，是实现煤炭深度脱硫降灰的有效技术途径。 According to the occurrence characteristics of high-sulfur coal in our country and the current technical foundation, the deep desulfurization and ash reduction of coal is proposed by using the combination of fine-medium heavy medium cyclone and selective fine-grained flocculation technology (FHMC-SF). FHMC-SF process using a single heavy medium cyclone and HM cyclone - microbubble flotation joint process, inorganic sulfur removal rate can be greatly improved, the lower limit of separation was significantly reduced, the coal is to achieve the depth of desulfurization ash Effective technical approach.
