Plant coke dry quenching furnace and coke dry quenching system

Abstract

The invention discloses a plant coke dry quenching furnace and a coke dry quenching system. Power plant flue gas is adopted as a circulating cooling gas for semi-coke quenching; after being introducedfrom the lower end of a circulating gas cooling chamber, the circulating cooling gas contacts with descending red coke in the circulating gas cooling chamber, and keeps going upward to enter an annular air channel from a chute formed in the circulating gas cooling chamber; the circulating cooling gas entering the annular air channel takes away the heat of the red coke and then is discharged froma circulating gas outlet; the discharged high-temperature circulating cooling gas passes through a heat absorption device; after the heat is absorbed and utilized by the heat absorption device, the temperature of the circulating cooling gas is lowered, and the circulating cooling gas enters from the lower end of the circulating gas cooling chamber to cool the red coke; with such circulation, the sensible heat of the red coke can be recycled while the absorbed heat can be delivered to the heat absorption device for heat recycling, thereby saving the resources; the circulating cooling gas is thepower plant flue gas which is circularly utilized without causing atmospheric pollution.

Description

technical field [0001] The invention belongs to the field of blue coke quenching, and in particular relates to a coke dry quenching oven and a coke dry quenching system in a factory. Background technique [0002] At present, the coke quenching section in my country's semi-coke production mainly adopts wet coke quenching or water mist coke quenching technology, that is, red coke is extinguished with water first, and then the coke is dried. This technology is simple and easy, but it causes waste of resources and air pollution. Pollution. Contents of the invention [0003] Aiming at the prior art, the present invention provides a coke dry quenching system in a factory and a coke dry quenching system. The dry coke oven is used to quench red coke, which can recover the sensible heat of red coke and save resources without producing Air Pollution. [0004] In order to solve the above problems, the present invention is achieved through the following schemes: [0005] A CDQ coke ...
