Technical field
The utility model belongs to the technical field that moisture drying is carried out to after-smithing petroleum coke, and in particular to a kind of calcined coke baking
Dry systems.
Background technique
Petroleum coke is that a kind of coke obtained is processed in the delayed coking of residual oil.Essence is a kind of part graphitized carbon element shape
State.Color is black porous, is in packed particle shape, cannot melt.Element composition is mainly carbon, or contain a small amount of hydrogen, nitrogen, sulphur, oxygen
With certain metallic elements, moisture is also had sometimes.
Calcined petroleum coke is mainly for the production of graphite electrode, carbon product, diamond dust, the industry of food-grade phosphorus, metallurgical industry
And calcium carbide etc., wherein widely used is graphite electrode.To make petroleum coke (green coke) to adapt to require, it is necessary to be forged to green coke
It burns.Calcination temperature is generally at 1300 DEG C or so, it is therefore an objective to remove volatile fraction in petroleum coke as far as possible.Petroleum coke can be reduced in this way to make again
The hydrogen content of product improves the degree of graphitization of petroleum coke, to improve the elevated temperature strength and heat resistance of graphite electrode, and changes
It has been apt to the conductivity of graphite electrode.Therefore, either electrolytic aluminium factory, independent charcoal ink factory and oil plant all compare concern petroleum coke
The progress and development of calcining technology.
The process flow of general carbon engineering project is next procedure will to be sent directly into after calcining petroleum coke both at home and abroad, is not necessarily to
It is dry.And calcining process of petroleum cokes (raw material production) is not provided in the process flow of many engineering projects, need strange land to purchase
After-smithing petroleum coke.Since after-smithing petroleum coke can absorb certain moisture during transport and storage, it can not meet carbon engineering
The technique requirement of project next procedure, it is necessary to increase by one of stoving process.
Summary of the invention
The utility model provides a kind of calcined coke drying system that drying effect is good and drying work aiming at the above problem
Skill.
In order to realize the above-mentioned purpose of the utility model, the calcined coke drying system of the utility model, including with combustion air
