随着人类社会的快速发展,煤炭等能源的日益紧缺,使得绿色能源太阳能的大规模开发和利用,从而太阳能电池板的原料多晶硅的用途越来越广泛,用量也越来越大,近几年来,我国多晶硅产业也呈现几何级数的发展态势.然而,随着我国多晶硅总产量的逐年增多,多晶硅生产的原辅材料单耗指标高、综合同收差、能耗高.目前全球用于生产多晶硅的方法主要有硅烷法（硅烷热分解法）、改良西门子法（闭环式三氯氢硅氢还原法）.当前生产工艺较成熟的是改良西门子法,改良西门子法是用氯气和氢气合成氯化氢（或外购氯化氢）,氯化氢和工业硅粉在一定的温度下合成三氯氢硅,然后对三氯氢硅进行分离精馏提纯,提纯后的三氯氢硅在氢还原炉内进行氢还原反应生产高纯多晶硅.还原工艺的成熟程度是决定多晶硅产量和产品质量的核心所在.还原是将经提纯和净化的三氯氢硅与氢气混合通入还原炉中,在1100℃～1200℃下将还原出来的多晶硅沉积的发热体的硅芯上.从而得到纯度很高的单质硅.本文对改良西门子法生产多晶硅还原工段的还原炉和水系统做了详细介绍以及还原过程中遇到的问题进行探讨,从而降低能耗,提高产品质量,使我国的多晶硅市场能在世界上占重要地位.

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
