摘要
采用静电场研究了添加团聚剂的水相中煤脱除成灰矿物的试验结果, 发现强的静电作用能促进煤中成灰矿物的脱除, 但可燃质收率有所降低; 另外, 添加某些化学药剂可进一步提高脱灰效果. 静电场的影响作用与成灰矿物颗粒本身的电特性有关, 强的静电作用有助于成灰矿物存在于水相中.
The test results of deashing from coal in aqueous phase added with agglome rator is studied by electrostatic field.It was found that the strong electrostatic function can improve the rate of deashing from the coal, but it also decreases the recovery rate of combustible matter. In addition,adding some chemical agents can further raise deashing effect. The affection of electrostatic field relates to the electro property of particle of the mineral, strong electrostatic function helps the minerals exist in aqueous solution steadily.
