Description

Technical Field

[0001] The utility model relates to the technical field of coking wastewater, in particular to a reaction device for deep desulfurization and decyanation of coking wastewater. Background Art

[0002] Coking wastewater is a typical industrial wastewater, and its source, characteristics and treatment methods all have obvious characteristics. Coking wastewater mainly comes from the primary cooling of coke oven gas, production water and steam condensate wastewater in the coking production process; specifically, these wastewaters are generated in the processes of coal coking, gas purification, chemical product recovery and chemical product refining.

[0003] In view of the above and existing related technologies, the inventor believes that there are often the following defects: special treatment equipment is used in the treatment of coking wastewater. When the treatment is completed, the container cover needs to be opened. Since the traditional treatment equipment lacks a special exhaust mechanism, the residual gas will directly contact the human body when the cover is opened, and it is very likely that there will be problems affecting the human body or the air; therefore, a reaction device for deep desulfurization and decyanation of coking wastewater is proposed for the above problems.
