Description
Technical Field
The utility model relates to a polycrystalline silicon preparation technical field, in particular to brush plating device.
Background
The inner wall of the existing polycrystalline silicon reduction furnace is usually made of stainless steel, the infrared reflectivity is low, most of near infrared light emitted by silicon cores can be absorbed and converted into heat energy, and then the heat energy is transferred to cooling water of the reduction furnace through the heat conduction effect so as to keep the inner wall of the reduction furnace at a low enough temperature, so that the strength of the reduction furnace can be kept within a safe range.
At present, polysilicon enterprises mostly use the modified siemens method to produce polysilicon. In the conventional modified siemens process, the energy lost in the form of radiant energy accounts for more than 60% of the total energy input to the reduction furnace.
