Description

Technical Field

[0001] The utility model relates to a dry coke quenching belt conveyor with a belt cooling function, belonging to the technical field of dry coke quenching belt conveyor structure improvement. Background Art

[0002] The dry coke quenching process is widely used in coke production because of its advantages of energy saving, environmental protection and improvement of coke quality. During the dry coke quenching process, red coke is loaded from the top of the dry coke quenching furnace, and the low-temperature inert gas is blown into the red coke layer in the cooling section of the dry coke quenching furnace by the circulating fan to absorb the sensible heat of the red coke. The cooled coke is discharged from the bottom of the dry coke quenching furnace. The coke discharged from the dry coke quenching furnace is transported to the coke screening building by the dry coke quenching belt conveyor. Since the coke temperature is still high at this time, the belt is kept in a high temperature state for a long time, which is easy to cause carbonization of the belt and shorten the service life of the belt; at the same time, the high-temperature coke is not conducive to timely transportation, which affects the timeliness of transportation.
