Abstract: A composite vortex reactor comprises a Rankine cyclone reactor and a Taylor vortex reactor. The Rankine cyclone reactor comprises a reaction chamber, a side wall of the reaction chamber is provided with a first inlet pipe and a second inlet pipe, and fluids entering the reaction chamber through the first inlet pipe and the second inlet pipe can form a gyro-fluid in the reaction chamber, and the middle of the top of the reaction chamber is provided with a gyroscopic outlet pipe. The Taylor vortex reactor comprises an inner cylinder and an outer cylinder which are coaxially provided, the inner cylinder is driven by a rotary driving device to rotate, an annular reaction space is formed between the inner cylinder and the outer cylinder. The upper end of the outer cylinder is provided with a reaction outlet pipe communicating with an upper portion of the annular reaction space.
