Abstract

The invention relates to a cooling structure for dry method coke quenching, which comprises a body, a gas distribution pipe, a gas collection umbrella and a baiting device, wherein the gas distribution pipe can guide cold smoke gas generated by drying treatment on coal briquettes into the body, and is arranged in the body, the gas collection umbrella can discharge the smoke gas through the heat exchange out of the body, and is arranged under the gas distribution pipe, and the baiting device can be used for carrying pyrolysate products in the body so that the pyrolysate products can be discharged from the cooling structure at the preset speed. The cooling structure for dry method coke quenching of the invention belongs to a semi-coking cooling structure using gas as a carrier, which can realize the dry method coke quenching. The structure realizes the dry method coke quenching by a specific structural method, saves the water sources, and simultaneously reduces the environment pollution.

Description

technical field [0001] The invention relates to a coal dry distillation device, in particular to a cooling structure for dry coke quenching. Background technique [0002] Dry coke quenching is referred to as "dry coke quenching", which is relative to the wet coke quenching in which water extinguishes hot coke. The basic principle is to use cold inert gas to exchange heat with hot coke in the dry quenching furnace to cool the coke. , the inert gas that absorbs the heat of red coke transfers the heat to the CDQ waste heat boiler to generate steam, which can be used to generate electricity through a steam turbine or meet the requirements of the production process, and the cooled inert gas is blown into the CDQ furnace by the circulating fan to cool the red coke . This technology has changed the waste of waste heat resources in the traditional wet coke quenching technology and the serious pollution of the atmospheric environment by the mist containing dust and toxic and harmful...
