Complete set of equipment for drying and disposal of tar residue

Overview of tar residue

Coke residue is a viscous solid oil residue produced in the coking production process, which is adsorbed with coal tar.,It is mainly composed of polycyclic aromatic hydrocarbons, benzene, phenols, and coal powder, coke powder, etc.,Coke residue has corrosive adhesion, and has a certain degree of fluidity at a certain temperature. Improper storage will cause serious pollution to the surrounding environment and groundwater resources. In addition, the volatile escape of tar residue gas makes the surrounding air suffer serious pollution, which affects the physical and mental health of enterprise employees. The tar residue is a hazardous solid waste specified by the State Environmental Protection Administration.,Among them, the tar residue in the tar storage facility in the coal tar refining process.(252-005-11),Clarification of tar residue at the bottom of the facility during coking(252-002-11),Coke residue in tar storage facilities during coking and coking by-product recovery(250-004-11),They are included in the National Hazardous Waste List.HWll Class.

Problems in the disposal of tar residue:

(1) Due to its high viscosity, tar residue is prone to reduce the accuracy of coal blending due to poor blanking.,Affect the stability of coke quality;

(24) The tar residue is generally stored in the coal yard. The smell of the tar residue affects the quality of the atmospheric environment in the area, and also affects the environment of the whole conveying channel during the transportation of coking coal, which has a great impact on the health of on-site workers;

(32) Content in tar residue30%-40%About coal tar, coal tar loss caused by combustion after coal blending with coke residue into the furnace,The yield of the coking product is reduced.

(4) In order to further reduce the coal chemical company's coke residue in the process of storage, transportation and disposal can not reach its atmospheric pollutant emission concentration limit, it is necessary to carry out harmless treatment of coke residue.

The process flow diagram is as follows:
