Description

Technical Field

[0001] The utility model relates to the technical field of coal tar recovery, in particular to a device for recovering coal tar. Background Art

[0002] Coal tar is also called coal paste, coal distillate, and coal tar solution. It is a black or dark brown viscous liquid obtained during the coal coking process. It has a higher specific gravity than water, has a certain solubility and a special odor, is flammable and corrosive. Coal tar is one of the products of crude coal gas generated by the pyrolysis of industrial coal in the coking industry. Coal tar acts on the skin and may cause dermatitis, acne, folliculitis, phototoxic dermatitis and cancer, may cause damage to the nasal septum, and may corrode the skin. Coal tar is harmful to the environment and can pollute the atmosphere. Therefore, it is necessary to effectively recycle and treat coal tar.
