Technical Field

[0002] Coke dry quenching is a quenching process relative to wet quenching, which uses inert gas to cool down the red-hot coke. During the coke dry quenching process, the red coke is loaded from the top of the dry quenching furnace, and the low-temperature inert gas is blown into the red coke layer in the cooling section of the dry 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 quenching furnace.
[0003] The external working environment of the traditional dry quenching coke system is open. The dry quenching coke oven is directly set on the foundation of the dry quenching coke oven. A hoist is set on one side of the dry quenching coke oven to lift the coke can to the top height of the dry quenching coke oven, and then the dry quenching coke can is transported to the top of the dry quenching coke oven through a horizontal running track. However, in this open working environment, the coke can is easily affected by the surrounding environment and weather during the lifting and transportation process, causing the coke can to deviate or tilt during the lifting, and the red coke in the coke can is easy to scatter, resulting in a waste of red coke resources; bad weather conditions can easily cause the coke can to shake during the lifting and transportation process, causing the risk of the coke can being unhooked, and the coke can plus the red coke is heavy, the lifting height is high, and the high-altitude translation distance is long.
