Patent ID: 8551295

Claim:
A reactive distillation apparatus for multistage counter-current rotating bed, comprising: a closed shell including a top cover, an isolation plate, a baseplate, an upper section defined between the top cover and the isolation plate, and a lower section defined between the isolation plate and the baseplate, wherein the upper section and the lower section are arranged in an axial direction of the closed shell; a revolving shaft provided along a vertical central axis of the closed shell and linking the upper section and the lower section; two or more rotors in series connection connected to the revolving shaft, wherein the rotors comprise an upper rotor positioned in the upper section and a lower rotor positioned in the lower section, each of the rotors comprises a rotating disc connected with the revolving shaft, a group of concentric dynamic filler rings with different diameters are installed on the rotating disc at intervals along a radial direction, walls of the dynamic filler rings are holed; static rings connected to the top cover and the isolation plate, respectively, wherein the static rings connected to the top cover are inserted into clearances between the dynamic filler rings of the upper rotor, the static rings connected to the isolation plate are inserted into clearances between the dynamic filler rings of the lower rotor, and walls of the static rings are holed; a feeding inlet, a reflux inlet and a gas outlet mounted on a top face of the top cover of the closed shell, while a waste liquid outlet and a gas inlet provided in the lower section above the baseplate of the closed shell; wherein the dynamic filler rings comprise a first filler ring filled with a catalytic filler and a second filler ring filled with a wire gauze filler with the first filler ring being positioned at an outer circle on the upper rotor and at an inner circle on the lower rotor, respectively, and the second filler ring being positioned at an inner circle on the upper rotor and at an outer circle on the lower rotor, respectively; a spray nozzle for raw material liquid arranged between the first filler ring and the second filler ring on the upper rotor; a spray nozzle for reflux arranged in an inner cycle of the innermost dynamic filler ring on the upper rotor; and a rotating liquid distributor arranged in an inner cycle of the innermost dynamic filler ring on the lower rotor.
