Abstract:
1. A fluidized bed reactor, comprising a reactor shell vertical to the ground, a phase separator at the upper part of the shell, and an inner circulation zone provided under the phase separator, wherein: said inner circulation zone comprises a cylinder, a tapered diffusion section and a guiding structure, wherein said cylinder and said tapered diffusion section at the lower end of the cylinder are both located within the reactor shell, said guiding structure is located on the inner wall of the reactor shell at the lower end of the tapered diffusion section, and said guiding structure is an annular protrusion on the inner wall of the reactor; said phase separator comprises an inner cylinder and an outer cylinder that are concentric with different inner diameters, wherein the upper and lower ends of the inner and outer cylinders are all open, the opening of the upper end of the outer cylinder is higher than the opening of the upper end of the inner cylinder, and the opening of the lower end of the outer cylinder is higher than the opening of the lower end of the inner cylinder; the lower end of the inner cylinder there is a tapered diffusion section, the diameter of the opening of which is less than the inner diameter of the reactor; and the lower end of the outer cylinder there is also a tapered diffusion section, the diameter of the opening of which is also less than the inner diameter of the reactor.
