Abstract

The invention relates to a use method of a super-gravity three-phase mass transferring and separating rotary bed, wherein the method comprises steps as follows: providing the super-gravity three-phase mass transferring and separating rotary bed; and using the super-gravity three-phase mass transferring and separating rotary bed for separation. The super-gravity three-phase mass transferring and separating rotary bed is divided into a super-gravity three-phase mass transfer section on the upper part and a whirl solid-liquid separation section on the lower part, and comprises a rotating shaft, a rotor, a conical static material liquid distributor, a rotary liquid distribution disc and a vortex stopping device. A gas phase outlet, a light phase outlet and a heavy phase outlet are formed in a shell of the super-gravity three-phase mass transferring and separating rotary bed. The super-gravity three-phase mass transferring and separating rotary bed has advantages as follows: 1, the mass transfer and the pre-separation or even complete separation of gas, liquid and solid phases are simultaneously realized, and the method is applicable to various unit operation processes such as rectification and absorption; and 2, the static-dynamic liquid distribution method not only simplifies the structure of a liquid inlet and is easy to seal, but also realizes axial and circumferential initial distribution of the liquid.

Description

technical field [0001] The present invention relates to the technical field of supergravity, in particular to a method for using a supergravity three-phase mass transfer separation rotating bed. Background technique [0002] Hypergravity field technology is a breakthrough technology for enhancing transport and multiphase reaction processes. In practical applications, the way to achieve a hypergravity environment is to generate centrifugal force through rotation. This specially designed rotating device is called a hypergravity machine or a hypergravity rotating bed, and is also known as "the chemical industry's first" because of its breakthrough advantages. transistor". However, the function of the supergravity rotating bed device currently used in the industry is limited to the mass transfer and separation of gas phase and liquid phase or solid-liquid mixture, and cannot realize the separation of gas, liquid and solid three phases while enhancing mass transfer. The prior a...

[0005] Chinese patent CN 1060415A proposes a rotating liquid distribution type rotating bed device that fixedly connects the liquid distributor to the rotor or components on the rotor. The liquid is distributed by the centrifugal force generated by the rotation, which improves the operating range of the liquid flow rate, but the liquid distributor and the liquid are separated The dynamic sealing structure is required between the material pipes, the structure of the distributor is complicated, and the production and installation are troublesome

Although this liquid distributor avoids the dynamic sealing structure between the liquid distributor and the feed pipe, it is easy to manufacture and install, but when the liquid flow rate is large, the flow resistance of the liquid distributor will be large, and the liquid atomization effect will be weakened
