Abstract:
1. An apparatus for manufacturing a high purity polycrystalline silicon, comprising: a vaporizer of silicon chloride; a fusing evaporator of zinc; a vertical reactor provided with a heating means on the peripheral face thereof; a silicon chloride gas supply nozzle disposed to connect the vaporizer of silicon chloride and the vertical reactor and for supplying a silicon chloride gas supplied from the vaporizer of silicon chloride into the vertical reactor; a zinc gas supply nozzle disposed to connect the fusing evaporator of zinc and the vertical reactor and for supplying a zinc gas supplied from the fusing evaporator of zinc into the vertical reactor; and an exhaust gas vent pipe connected to the vertical reactor, the fusing evaporator of zinc, further comprising: a zinc evaporator; a main vertical cylinder part connected to the upper part of the zinc evaporator; a solid trapping pipe inserted into the main vertical cylinder part; a zinc introducing pipe connected to the solid trapping pipe at an angle; a seal pot disposed to surround the lower end opening portion of the solid trapping pipe and for configuring the bottom face of solid trapping pipe; an induction heater disposed on the peripheral face of the main vertical cylinder part and capable of controlling a temperature; and a gas vent pipe connected to the side wall of the zinc evaporator.
