研究油团含水率、搅拌时间、球团大小、充气量以及分段加油等对大同煤油团聚脱灰工艺的影响。结果表明,在油团聚脱灰过程中充入一定量的空气以及分段加入柴油有利于油团聚脱灰。通过搅拌时间与球团大小以及灰分的关系,球团大小与含水率的关系,可以确定最佳的团聚时间。经过一次油团聚脱除灰分,煤的灰分可以达到1.89%,灰分去除率可以达到88.77%。 The effects of moisture content, mixing time, pellet size, aeration volume and segmented fueling on the delignification process of Datong kerosene were studied. The results show that adding a certain amount of air during the process of deaggregation of the oil and adding the diesel oil in stages can facilitate the oil deaggregation. The optimum agglomeration time can be determined by the relationship between the mixing time and pellet size and ash content, pellet size and moisture content. After an oil agglomeration to remove ash, coal ash can reach 1.89%, ash removal rate can reach 88.77%.
