Introduction to Dry Quenching Process and Equipment

Dry quenching is a method of cooling red coke using inert gas. In the process of dry quenching, red coke is loaded from the top of the dry quenching furnace, and low-temperature inert gas is blown into the red coke layer of 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 from the annular flue of the dry quenching furnace undergoes heat exchange through the dry quenching furnace. The boiler generates steam, and the cooled inert gas is re blown into the dry quenching furnace by the circulating fan for reuse.

The dry quenching process mainly consists of a red coke loading system, a cold coke discharge system, a dry quenching furnace and gas supply device, a gas circulation system, a boiler system, a water treatment system, and other components. The main facilities include a dry quenching furnace, loading device, coke discharge car, elevator, motor car and coke tank trolley, coke tank, primary dust collector, secondary dust collector, dry quenching boiler unit, circulating fan, dust removal ground station, water treatment unit, etc. The main equipment included in the dry quenching system varies depending on the actual engineering design.
