Points Of Polysilicon Reduction Process Design

The polysilicon is important material of the morden communication industry and solar battery industry. At present the producing process of Polysilicon that was applied widely is the improve simens process. The polysilicon aggrading reaction is the pivotal part of improve simens process, the design of process conditions and the equipments and the control project determines the advance of manufacture. And it directly determines the cost and consume of energy in the producing polysilicon,This article analyses the improve simens process, It confirms the design cruces and the most optimizing improve simens process, the control project, the key equipments.By the analyse of the system of reusing energy. This article accounts the amount of reusing energy and designs the system of reusing energy.The analyse of process and the course of design provide the reference for Polysilicon manufactory and polysilicon process design.
