Abstract
The invention discloses a dry quenching waste gas recycling system and method, and belongs to the technical field of coking waste heat recovery and smoke purification, the dry quenching waste gas recycling system comprises a dry quenching furnace for producing waste gas, and a smoke outlet of the dry quenching furnace is sequentially connected with a first heat exchanger, a dust removal device, a sulfur removal device, a dehumidification device, a second heat exchanger and an underground combustion chamber through a pipeline; the dry quenching waste gas is subjected to dust removal, sulfur removal, dehumidification and pollution impurity removal, heat value recovery through multiple times of heat exchange and then input into a combustion chamber, and the combustion degree is adjusted through nitrogen while combustibles are recovered. According to the invention, the dry quenching waste gas can be fully and reasonably recycled, so that the waste of resources can be reduced, and the environment-friendly requirement can be met.
