The invention relates to a graphite part purifying device, comprising a cylindric shell with a pedestal, a hermetic door located at one side of the shell, a cavity located in the shell and a support located in the cavity and used for placing of a graphite part, wherein three electrodes with cooling water jackets are uniformly distributed on the shell and connected with a power supply, the upper part of the shell is provided with a tail gas pipe orifice, the bottom of the shell is provided with an air inlet pipe orifice, a heat insulating graphite net is arranged at the joint of the shell and the cavity, three graphite electrodes are arranged between the cavity and the support and are connected with the three electrodes with the cooling water jackets in the manner of one-to-one correspondence, the tail gas pipe orifice is connected with a vacuum pump, and the air inlet pipe orifice is connected with a chlorine tank. The graphite part purifying device can effectively remove impurities in the graphite part, thereby guaranteeing purity of polysilicon.
Description
technical field [0001] The invention relates to a purification device, in particular to a graphite component purification device. Background technique [0002] The graphite parts used in polysilicon electrodes are all high-purity graphite, but graphite parts will be polluted during the process of manufacturing. The surface and interior of graphite parts will be polluted with metal impurities, boron, phosphorus, arsenic, grease, etc. Elements, boron, phosphorus, arsenic, etc. In the polysilicon production process, graphite parts are in direct contact with polysilicon products, and impurities in graphite parts will enter into polysilicon products, affecting the purity of polysilicon products. [0003] At present, the purification technology of graphite components mainly consists of the following two types: [0004] One is to use strong acid (concentrated nitric acid) to soak, then use pure water to wash and dry. This method uses the oxidizing property of strong acid to oxidi...
