The invention discloses a technology based on cold drum electric capture in coal production, the raw coal gas from the coke oven, tar and ammonia water go to the gas-liquid separator along the gas suction pipeline, and the liquid separated in the gas-liquid separator Separation from the flow into the mechanized ammonia water clarification tank, the separated ammonia water enters the circulating ammonia water tank, and part of it is sent to the coke oven bridge pipe and gas collecting pipe as circulating ammonia water to spray, condense and cool the raw coal gas, and the separated tar enters the tar storage tank after standing and dehydrating Export: The tar residue settled at the bottom of the mechanized ammonia clarification tank is discharged to the tar residue truck. After the gas-liquid separation, the raw coal gas comes out from the upper part of the gas-liquid separator and enters the horizontal tube primary cooler. After the horizontal tube primary cooler is divided into two stages and indirectly cooled by water After entering the electric tar collector to remove the tar mist, it is sent to the desulfurization section by the gas blower. The process can effectively purify the gas, so that the impurity content is low, the obtained gas produces less harmful substances during subsequent combustion, has low pollution to the environment, and improves the competitiveness of the enterprise.
