The invention discloses a coke oven gas recycling system, which comprises a coke oven. The side wall of the coke oven is communicated with a first gas guide pipe; a turning mechanism rotationally penetrates through the top surface of the coke oven; the gas outlet of the first gas guide pipe is communicated with an evaporation box; a second gas guide pipe is fixedly connected in the evaporation box; the gas inlet of the second gas guide pipe is communicated with the gas outlet of the first gas guide pipe; the gas outlet of the second gas guide pipe penetrates through the side wall of the evaporation box; evaporation liquid is arranged in the evaporation box, a feeding port is formed in the top face of the evaporation box and filled with a sealing plug, a control box is fixedly connected between the coke oven and the evaporation box, a pneumatic control mechanism is arranged on the inner wall of the control box, the pneumatic control mechanism is communicated with the evaporation box, and a rotating mechanism driven by the pneumatic control mechanism is rotatably connected to the bottom of the control box. Coking coal can be turned over conveniently, heating is more uniform, the coking efficiency is improved, in addition, heat in exhaust gas can be recycled, and the utilization rate of energy can be increased.
Description
technical field [0001] The invention relates to the technical field of energy saving and environmental protection in the coking industry, in particular to a coke oven gas recovery and utilization system. Background technique [0002] Coking production in coking plants is actually a typical process of energy reprocessing and heat energy recovery and reuse, and coke and coking gas are its main energy products. During the coke production process, the mixed coal is isolated from the air and heated to dry distillation in the coke oven, and a large amount of raw gas is produced while coke is produced. [0003] The retrieved patent number: CN108728135B discloses a coke oven gas separation and recycling method, which belongs to the technical field of energy saving and environmental protection in the coking industry. A coke side coke oven gas recovery system is installed on the coke side of the coke oven carbonization chamber to recover the raw gas produced in the coke oven carboniz...
