摘　　要：针对东辰公司选煤厂原有压滤机压滤煤泥水分高、掺销影响经济效益等问题,采用超高压压滤机对浓缩机底流进行压滤试验。结果证明:压滤煤泥水分比2023年1-5月降低10.14%,发热量提高2.33 MJ/kg,滤饼破碎后粒度均匀小于10 mm、人工挤压不成团。测算超高压压滤机改造经济效益显著,投资回收期短。In order to solve the problems such as high water content of coal slime filtered by the original filter press in the coal preparation plant ofDongchen Company and the influence of mixing and selling on economic benefits,the filter press test of thickener bottom flow was carried out by using ultra-high pressure filter press.The test results show that the water content of compressed coal slime is reduced by 10.14%,the calorific value is increased by 2.33 MJ/kg,the particle size is less than 10 mm after the filter cake is broken,and the group is not formed by artificial extrusion.It is estimated that the transformation of ultra-high pressure filter press has significant economic benefits and short investment payback period.
