Description

Technical Field

[0001] The utility model relates to the technical field of CDQ furnace pipelines, in particular to a pipeline system device for reducing the burning loss of a CDQ furnace. Background Art

[0002] Coke dry quenching is a method of cooling red coke using inert gas. During the coke dry quenching process, 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 chamber of the dry quenching furnace by the circulating fan to absorb the heat of the red coke. The cooled coke is discharged from the bottom of the dry quenching furnace, and the high-temperature inert gas coming out of the annular flue of the dry quenching furnace is heat exchanged through the dry quenching boiler. The boiler generates steam, and the cooled inert gas is re-blown into the dry quenching furnace by the circulating fan for recycling. Coke dry quenching is superior to wet quenching in terms of energy saving, environmental protection and improving coke quality.

[0003] Usually, the heat in the CDQ furnace needs to be discharged from a pipe to reduce the burning loss of the CDQ furnace. However, the existing device usually has a filter at the front end of the pipe to isolate the coke blocks mixed in it when the heat is discharged. However, usually only larger coke blocks can be isolated, and smaller ones cannot be isolated. If the filter holes on the filter are too fine, it will affect the flow of hot air, so the smaller coke blocks will flow into the heat recovery device with the hot air, affecting the operation and service life of the heat recovery device.
