Research on centrifugal drying of coal tar residue based on different separation factors
The principle of mechanical separation and drying of coal tar residue,the index and test method of separation efficiency of coal tar residue and the main factors affecting separation and drying were introduced.The solid-liquid two-phase separation of coal tar residue was carried out with the centrifuge,so as to realize the harmless treatment of coal tar residue.According to the laboratory experiment,the higher the centrifuge separation factor and the higher the material temperature during the separation,the better the separation efficiency of coal tar residue.In the practical application in the factory,the separation efficiency of coal tar residue was not only related to the separation factor,but also related to the centrifuge selection.If the conical-basket centrifuge was used,it was also necessary to choose the appropriate separation factor and drum cone angle according to the friction coefficient of the material.
