Revolving bed

Abstract

The invention discloses a revolving bed, which comprises a revolving bed layer, a liquid phase distribution pipe, a gaseous phase inlet and a gaseous phase outlet, a liquid phase inlet and a liquid phase outlet, a shell, a composite impeller, a mud baffle ring and a mud collection box. Two ends of the shell are provided with the gaseous phase inlet and the gaseous phase outlet respectively; the liquid phase distribution pipe has a cylindrical structure, of which the pipe wall is provided with liquid distribution holes; the liquid phase distribution pipe is both used as a rotating shaft of therevolving bed layer and the composite impeller; the composite impeller is arranged at a position close to the gaseous phase inlet; the mud baffle ring has an annular structure, which is close to the shell and fixed between the revolving bed layer and the composite impeller; the mud collection box is arranged at the bottom of the shell corresponding to the composite impeller; the liquid phase inlet is connected with the liquid phase distribution pipe through a revolving joint; and the liquid phase outlet is arranged at the bottom of the shell. The composite impeller removes the micro solid particles in a gaseous phase so as to realize the pretreatment on the gaseous phase and prevent the revolving bed layer from scaling. The revolving bed is applicable to gaseous phase and liquid phase mass transfer and reaction, particularly the gaseous phase and liquid phase mass transfer and reaction with micro solid particles.

Description

technical field [0001] The invention relates to a rotating bed, in particular to a device for completing gas-liquid mass transfer, reaction, and gas-solid separation using a high-speed rotating bed layer in a state of supergravity. Background technique [0002] The mass transfer and reaction equipment of the high gravity field rotating bed is a new type of chemical unit equipment developed in the early 1980s. Compared with the traditional technology, the high-gravity field rotating bed mass transfer equipment has the characteristics of high mass transfer intensity, small equipment size, short material residence time, low liquid holding capacity, and no flooding. [0003] Usually, the high-gravity field rotary bed equipment is composed of a shell, a rotor (reaction bed) and a motor. The rotor is mostly made of porous media, where the materials undergo mass transfer and reaction. The gas phase needs to be transported by a fan, especially when the gas-liquid countercurrent sta...

Problems solved by technology

CN2581060Y discloses a rotating bed supergravity multiphase reactor, which adopts a spiral channel type rotating bed, and the helix is ​​an Archimedes helix, which can obtain a long gas-liquid two-phase contact path, but the resistance is large and there is no pumping. Suction capacity, especially the gas phase contains more solid particles, so it is easy to block the bed
