The present invention relates to system, the system used in a kind of chlorination Rock coal containing alum to include：Ore grinding device, blending bunker, chlorination system, dust-precipitator, condenser system.The invention further relates to the method for chlorination Rock coal containing alum.The characteristics of silicon high for the low vanadium of bone coal high-carbon of the invention, with chlorine carburizing chlorination, and collect product and removal of impurities using condensing means, two kinds of elements of vanadium and silicon therein are reclaimed simultaneously, obtained major product is the chloride of vanadium, vanadium chloride content reaches more than 90%, can significantly reduce the energy consumption of subsequent processing steps, improves economy.Waste water is not produced using chloridising processing Rock coal containing alum, the chlorination rate of vanadium is high, and tail gas can recycle. |
