Title: FLUIDIZED BED REACTOR FOR SYNTHESIZING TRICHLOROSILANE
Abstract:
According to one embodiment of the present invention, a fluidized bed reactor for synthesizing trichlorosilane comprises: a reactor of which the inner space is set such that metal grade silicon reacts with a feed gas by hydrochlorination and direct chlorination so as to produce trichlorosilane gas; a cyclone for collecting fine particles micronized from metal grade silicon and rising in the inner space of the reactor; a bypass line connected to the reactor so as to discharge the fine particles to the outside of the reactor; a bypass valve provided on the bypass line; and a separation and treatment device connected to the bypass valve, and separating the fine particles from a discharge gas to be discharged from the reactor and treating the same.
