Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery from dry coke quenching, and particularly discloses a waste heat recovery device for dry coke quenching. Background Art

[0002] CDQ refers to a coke quenching method that uses inert gas to cool down red coke. During the CDQ process, high-temperature red coke is loaded from the top of the CDQ furnace. Low-temperature inert circulating gas is blown into the red coke layer in the cooling section of the CDQ furnace by a circulating fan, absorbing the sensible heat of the red coke. The high-temperature inert gas exiting the CDQ furnace's annular flue flows through the CDQ boiler for heat exchange. The boiler generates steam, and the inert gas is circulated in a closed system.

[0003] Chinese patent CN220110642U discloses a waste heat recovery device for dry quenching coke, comprising a housing, a filter screen, a brush, a first linear bearing, a first guide shaft, a connecting plate, and a first handle. During use, pulling or pushing the first handle causes the connecting plate to reciprocate. Supported by multiple first linear bearings, the multiple first guide shafts can reciprocate synchronously. This in turn drives the multiple brushes to reciprocate synchronously, removing coke dust accumulated on the surfaces of the multiple filter screens. The filter screens can be cleaned without disassembling them, making the operation simple and convenient for cleaning coke dust.

[0004] The above-mentioned document discloses a waste heat recovery device for dry quenching of coke. This device requires the operator to manually push and pull the first handle to clean the filter screen, which is time-consuming and labor-intensive. In addition, the cleaned coke powder needs to be shut down and the box door opened before it can be discharged from the box, which reduces production efficiency. Therefore, a waste heat recovery device for dry quenching of coke is needed to solve this problem. Utility Model Content
