Problems solved by technology

[0002] Tar residue is a kind of industrial waste produced in the production process of coking industry. It is a viscous solid waste residue with coal tar adsorbed in the coking production process. It is mainly composed of polycyclic aromatic hydrocarbons, hydrocarbons, phenol and naphthalene, and coal powder. Composed of , coke powder, tar residue is corrosive and adhesive, has a certain fluidity at a certain temperature, and is easy to adhere to the equipment. It is extremely viscous at room temperature and is difficult to use directly.

Abstract

The invention discloses a circulating fluidized bed boiler tar residue blending combustion system and a working method thereof, and belongs to the technical field of harmful solid waste treatment andmetallurgical waste comprehensive utilization. The system comprises a dehydration system, a deoiling system, a pneumatic conveying system, a mixing system, a conveying system and a circulating fluidized bed boiler, wherein the dehydration system is connected with the deoiling system, the deoiling system and a dry pulverized coal feeding device are connected with the mixing system through the pneumatic conveying system, and the mixing system is connected with a feeding port of the circulating fluidized bed boiler through the conveying system. The system is flexible in arrangement and high in automation degree, heat is recovered while harmless treatment of tar residues is achieved, environmental pollution is reduced, and considerable economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of hazardous solid waste treatment and comprehensive utilization of metallurgical waste, and specifically relates to a circulating fluidized bed boiler burning tar residue system and a working method thereof. Background technique [0002] Tar residue is a kind of industrial waste produced in the production process of coking industry. It is a viscous solid waste residue with coal tar adsorbed in the coking production process. It is mainly composed of polycyclic aromatic hydrocarbons, hydrocarbons, phenol and naphthalene, and coal powder. Composed of , coke powder, tar residue is corrosive and adhesive, has a certain fluidity at a certain temperature, and is easy to adhere to the equipment. It is extremely viscous at room temperature and is difficult to use directly. With the continuous increase of my country's total iron and steel production, coke production has also maintained a year-by-year growth trend. Th...
