Background

Along with the increasing scale of the coal chemical industry devices in the jin-coaling group, the heat recovery of the crude gas gasified by the jin-coaling GS furnace is particularly emphasized, and in the process flow, the crude gas produced from the jin-coaling GS furnace is cooled by a cyclone separator, a medium-pressure waste heat recoverer and a low-pressure waste heat recoverer and then is sent to a downstream process. The temperature of the crude gas produced from the jin coal GS furnace is about 540-650 ℃, the crude gas needs to be cooled to 160-200 ℃ to meet the requirements of downstream processes, and if the crude gas is cooled by adopting measures such as chilling, the crude gas can achieve the effect of cooling, but the energy is not fully utilized, and the waste of water resources is caused.
