采用浓密机洗涤浸出矿浆,一般需要进行多级洗涤才能达到洗涤效果,这样设备费用较高,占地面积亦大,设备结构也比较复杂。因此试验采用流态化洗涤塔代替浓密机进行洗涤和液固分离。由于流态化洗涤塔系运用逆流原理,传质效率高,可以使洗涤过程得到强化。 Thickened machine leaching pulp, the general need for multi-level washing to achieve the washing effect, so that higher equipment costs, covers an area is also large, the structure of the device is also more complicated. Therefore, the test fluidized scrubber instead of thickener washing and liquid-solid separation. As the fluidized scrubber system uses the countercurrent principle, the mass transfer efficiency is high, which can enhance the washing process.
