Abstract

A reactive distillation apparatus for multistage counter-current rotating bed includes a closed shell, in the center of which a revolving shaft linking each shell section is set, the shaft is provided with two or more rotors in series connection, a feeding inlet, a reflux inlet and an outlet of the gas phase are mounted on the top end face of the shell while a waste liquid outlet and an inlet of the gas phase are set on the bottom end face of the shell, a group of concentric dynamic filler rings with different diameters are installed at intervals along the radial direction, wherein the wall of the dynamic filler rings is holed, and the ring clearance between the dynamic filler rings is configured with static rings fastened on the static disc; a feeding inlet is arranged on the top cover of the shell corresponding to the spray nozzle of raw material liquid; a rotating liquid distributor is arranged on the inner side of the innermost dynamic filler ring of the said lower rotor.
