THERMAL PLASMA FLUIDIZED BED REACTOR AND METHOD FOR PREPARING POLYSILICON USING THE SAME

摘要

PURPOSE: A heat plasma fluidized-bed reactor for manufacturing silicon and a method for manufacturing the silicon using the same are provided to obtain cost profitability and excellent maintenance of a reaction temperature by raising heat reduction reaction using heat energy obtained from heat plasma and to discharge explosive materials. CONSTITUTION: A heat plasma fluidized-bed reactor(100) for manufacturing silicon comprises: a plasma torch part(110) equipped with an electrode rod(111) generating the heat plasma in internal space; a reactant supply part(120) supplying the reactant to the plasma torch part; a gas supply part(130) supplying reaction gas or carrier gas to the plasma torch part; and fluid bed reactor(140) reacting the reactant and the reaction gas.
