(EN) Apparatus and process for the production of silicon
(ZH) 硅制造装置和方法
要約
(EN)
An apparatus for the production of silicon which is provided with a tubular reactor (10) for conducting the reaction of zinc with a silicon compound, zinc feed pipes (30, 30') which each bear both a heating section for heating zinc to generate zinc gas and a zinc ejection section for feeding zinc gas by ejection into the reactor, zinc introduction sections (40A, 40B) for introducing zinc into the zinc feed pipes, silicon compound feed pipes (50, 50A, 50B, 50C, 50c, 54, 57, 90) provided with silicon compound ejection sections for feeding a silicon compound gas by ejection into the reactor in such a way that the silicon compound gas flows in the reactor from the bottom to the head, and a heating oven (20) set outside the reactor which forms such a heating zone (alpha) as to cover part of the reactor, the heating sections, and the zinc ejection sections and which heats them in such a way as to give such an inner temperature distribution of the reactor in which zinc gas and the silicon compound gas flow that the temperature on the center axis (C) side is lower than that on the sidewall side.

(ZH)

本发明提供一种硅制造装置,其具有反应管(10)、锌供给管(30、30’)、锌投入部(40A、40B)、硅化合物供给管(50、50A、50B、50C、50c、54、57、90)和加热炉(20);所述反应管用于使锌和硅化合物反应;所述锌供给管具有对锌进行加热、生成锌气体的加热部和向反应管内吐出锌气体而进行锌气体的供给的锌吐出部;所述锌投入部用于将锌投入到锌供给管内;所述硅化合物供给管具有硅化合物吐出部,该硅化合物吐出部用于将硅化合物气体向反应管内吐出而进行硅化合物气体的供给,使得硅化合物气体在反应管内从下方向上方流动;所述加热炉通过被设置在反应管的外方而划分出加热区域(α),将反应管的一部分、加热部和锌吐出部设置在加热区域内进行加热,使得流通锌气体和硅化合物气体的反应管内的温度分布为反应管的中心轴(C)侧比反应管的侧周面侧低。
