Needle Coke Production Line Equipment
Product introduction:
Needle coke is a high-quality variety developed vigorously in carbon materials. Its appearance is silver-gray, metallic lustrous porous solid. Its structure has obvious flow texture, large and few pores and slightly oval shape. The particles have a large aspect ratio, such as fibrous or needle-like texture direction, which has a sense of lubrication, it is the raw material for the production of high-end carbon products such as ultra-high power electrodes, special carbon materials, carbon fibers and their composites. According to the production of different raw materials, needle coke can be divided into oil needle coke and coal needle coke two. The needle coke produced from petroleum residue is oil-based needle coke; the needle coke produced from coal tar pitch and its fractions is coal-based needle coke.
Carbon calcination rotary kiln is one of the key equipment for needle coke production. The structure and operation process of needle coke rotary kiln directly affect the quality and production cost of needle coke products, and the calcination temperature and temperature distribution are important factors affecting the quality of calcination.
The combustion process inside the rotary kiln is actually a very complex turbulent flow and combustion chemical reaction process. Flow is a typical turbulent, gas-solid two-phase multi-component flow; heat transfer includes convection heat transfer, radiation heat transfer and heat conduction three heat transfer methods; combustion involves solid phase particles and gas phase combustion two parts; particle combustion and surface liquid evaporation, particle volatilization, particle oxidation and so on.
