Abstract

The invention discloses a combined type heat / electricity insulation device for a hydrogenation furnace, belonging to the field of insulation devices. The combined heat / electricity insulation device for the hydrogenation furnace comprises a chassis of the hydrogenation furnace, wherein an electrode is arranged on the chassis, a ceramic cup is sleeved outside the electrode, an upper port and a lower port are arranged on the ceramic cup, the electrode penetrates through the upper port of the ceramic cup, the lower port of the ceramic cup is arranged on the chassis, and the lower part of the electrode is covered in the ceramic cup. The combined type heat / electricity insulation device for the hydrogenation furnace has a simple structure, is convenient to machine, and can effectively insulate radiation of heat in the hydrogenation furnace to an insulation sleeve so that the service life of the insulation sleeve is prolonged. Meanwhile, due to the adoption of the combined type heat / electricity insulation device for the hydrogenation furnace, ground fault blowing-out caused by lap joint of the delaminated surface of a heater with the electrode and the chassis can be avoided, production efficiency and equipment utilization rate are increased, and replacement frequency and time of an insulation ring are reduced, and the hydrogenation furnace is ensured to be stably operated for a long time.

Description

technical field [0001] The invention relates to a heat insulation and insulation device, in particular to a heat insulation and insulation device used in a hydrogenation furnace in the production process of polysilicon. Background technique [0002] in SiHCl 3 A large amount of by-product SiCl will be produced in the synthesis process and hydrogen reduction process to prepare polysilicon 4 , if it cannot be recycled effectively, it will not only cause a huge waste of resources, increase production costs, but also cause serious environmental pollution and catastrophic consequences. At present, the best way is to combine SiCl 4 After hydrogenation, it is converted into trichlorosilane, which not only handles the by-product SiCl 4 , also regained the raw material SiHCl for polysilicon production 3 At present, most domestic polysilicon enterprises use the thermal hydrogenation method for SiCl 4 processing. However, the thermal hydrogenation furnace currently used in the t...
