1. A high-efficiency energy-saving white carbon black synthesis process by a gas phase method is characterized in that:

  • continuously and stably inputting a mixture of two silicon halide compounds after preheating treatment, air and hydrogen into a reactor in proportion for mixing, carrying out high-temperature combustion hydrolysis reaction in a synthesis furnace, continuously cooling the synthesis furnace by hot water with pressure of 0.15 +/-0.05 MPa in the reaction process, heating reaction raw materials by using heat released by the reaction, adjusting the mixing molar ratio of the raw materials to silicon halide compounds of 1;

    silicon halide compounds of 2;

    air;

    hydrogen of 1;

    0.8-1.2;

    15-35;

    1-3, controlling the inlet and outlet temperatures of hot water to be 95 +/-5 ℃ and

    110 +/-5 ℃

    respectively, and continuously cleaning the furnace by a cage type furnace cleaning device.
