Abstract

The invention discloses a production process of a carbon calcined rotary kiln in the field of carbon production and in particular relates to a method and a device for cooling high-temperature calcined coke of a carbon rotary kiln. The method for the cooling high-temperature calcined coke of the carbon rotary kiln comprises the following steps of: guiding the high-temperature calcined coke into a cooling jacket after passing through a launder at the bottom of a rotary kiln head; and after continuously discharging downwards, guiding the high-temperature calcined coke into discharge equipment for discharging from the cooling jacket. The method and the device solve the problems of poor cooling effect, oxidation of high-temperature materials, waste of cooling water resource, severe operating environment condition, serious water pollution, high cost of a cooling water circulation and processing system and waste of heat carried by the high-temperature calcined coke in the process of calcining petroleum coke.

Description

technical field [0001] The invention relates to a carbon calcining rotary kiln production process in the field of carbon production, in particular to a cooling method and device for high-temperature calcined coke in a carbon rotary kiln. Background technique [0002] Petroleum coke calcination is an important link in the carbon production process. Its function is to calcine the raw material → petroleum coke in the rotary kiln at high temperature to eliminate the volatile matter contained in petroleum coke, increase its true specific gravity, and reduce its specific gravity. Electrical resistance, so that the physical and chemical indicators of the calcined petroleum coke meet the requirements for raw materials in the production of carbon products. [0003] Carbon calcination rotary kiln is currently the main equipment for calcination of petroleum coke, and its calcination temperature is as high as 1350°C. During the production process, when the calcined coke is discharged f...
