The invention relates to the technical field of
tar residue treatment, and provides a
tar residue collecting and
drying device which is used for collecting and
drying tar residues in an
ammonia water clarifying tank and comprises a scraper conveyor, a
homogenizer, a centrifugal
machine, a dry residue collecting box, a liquid collecting box and a liquid return pump. An outlet of the scraper conveyor is connected with an inlet of the
homogenizer, an outlet of the
homogenizer is connected with an inlet of the centrifugal
machine, the centrifugal
machine is provided with a
slag outlet and a liquid outlet, the
slag outlet is connected with the dry
slag collecting box, the liquid outlet is connected with the liquid collecting box, the liquid return pump is arranged in the liquid collecting box, and an outlet of the liquid return pump is connected with the
ammonia water clarifying tank. The homogenizer and the centrifugal machine are arranged, the homogenizer pretreats the tar residues, and due to the fact that the
viscosity of the tar residues is large, the
centrifugal separation effect of the centrifugal machine can be improved after the tar residues are pretreated through the homogenizer, tar contained in the separated tar residues is reduced, peculiar smells in the dry residue collecting box are reduced, and follow-up treatment is facilitated.
