Embodiment
[0008] Based on the technology of cold drum electric capture in coal production, the gas indirect pipe-type initial cooling process is adopted, that is, the raw gas from the coke oven, tar and ammonia water are taken to the gas-liquid separator along the gas-suction pipeline, and in the gas-liquid separator The separated liquid flows into the mechanized ammonia water clarification tank for separation. After the separated ammonia water enters the circulating ammonia water tank, part of it is sent to the coke oven bridge pipe and gas collecting pipe to spray and condense the raw gas, and the rest is sent to the ammonia distillation device as residual ammonia water. After treatment, the phenol-cyanide waste water is sent to the sewage treatment station for biochemical treatment and reuse after reaching the standard, and it is not allowed to be discharged directly. The separated tar enters the tar storage tank and is sold after static dehydration (the separated water produced by the...
