With the rapid development of human society, coal and other energy sources become increasingly scarce, making large-scale solar energy development and utilization of solar panels so that the raw materials more and more extensive use of polysilicon, increasing consumption in recent In recent years, China's polysilicon industry the development of a situation geometrically. However, as China's production is increasing year by year polysilicon, polysilicon production unit consumption of raw and auxiliary materials indicator of the high-and integrated with the land poor, high energy consumption. Polysilicon used in the production of the world's main methods of silane method (pyrolysis of silane), improved the Siemens method (closed-loop-type hydrogen trichlorosilane reduction). The current more mature production technology of Siemens method is improved, improving Siemens is synthesized by chlorine and hydrogen chloride (or outsourcing hydrogen chloride), hydrogen chloride and industrial silica temperatures in trichlorosilane synthesis, and then trichlorosilane were separated by distillation purification, after purification of trichlorosilane reduction in the hydrogen furnace for hydrogen reduction reaction of high-purity polysilicon production. Reduction process is to determine the maturity of the polysilicon production and product quality of the core Reduction is that the purification and the purification of trichlorosilane and hydrogen reduction furnace mixed access, in the 1100 ℃ ~ 1200 ℃ will be restored by heating polysilicon deposition on silicon core body. Resulting in high purity silicon simple substanceIn this paper, improved production of polysilicon Siemens to restore the section of the reduction furnace and water system, introduced in detailas well as to restore the process to explore the problems encountered, thereby reducing energy consumption, improve product qualityso that thepolysilicon market in China in accounted for the important position of the world
