  • Patent number: 11511250
    Abstract: A method and apparatus for preparing a composite, in which the angle between the apparatus base and the apparatus body is adjusted by the elevator device, the solid raw material is loaded into the reactor by the solid feeding device, the main reaction gas, the auxiliary gas and the carrier gas are introduced from the front gas intake unit into the main reaction zone at a preset ratio, followed by the active material deposited on solid particles, the post-processing reaction gas is introduced from the middle gas intake unit to the post-processing reaction zone to form a functional layer on the active material, the prepared composite powder is separated and collected from the gas-solid mixture in the collection device. The exhaust gas is released from the exhaust manifold into an exhaust gas treatment system after minority powder filtered by the filter.
