A high-gravity rotating bed device with staged liquid feeding and enhanced rotor end effect

Abstract

The invention discloses a supergravity rotating bed device adopting sectional type liquid feeding mode to strengthen the rotor end effect, belonging to the technical field of supergravity. The device disclosed by the invention comprises a closed shell, wherein a rotating shaft penetrating through each shell section is arranged in the center of the shell; a filler layer is arranged in a rotor; a liquid inlet, a liquid outlet, a gas outlet and a gas inlet are formed on a cavity; multiple liquid feeding shower pipes which are concentrically distributed are radially fixed in a sectional mode on the lower end surface of a cavity gland; the filler layer comprises multiple sections of annular filler layers which are distributed in a radial parallel mode along the rotating shaft; and the liquid feeding shower pipes are distributed between every two adjacent sections of annular filler layers. Multiple end effect regions are manufactured on rotor filler layers by adopting a sectional type liquid feeding mode, thereby enabling all fillers to be fully utilized and achieving the purpose of strengthening mass transfer; and the mass transfer efficiency can be improved by 40-60%. The device disclosed by the invention is suitable for a reaction system requiring long reaction retention time and large mass transfer coefficients and is particularly suitable for gas-liquid absorption systems and the like which include viscous fluid transfer courses and are difficult to implement. The device disclosed by the invention can be used for a vertical rotating bed or a horizontal rotating bed.

Description

technical field [0001] The invention relates to a high-gravity rotating bed device that enhances rotor end effect by segmental liquid feeding, and specifically relates to manufacturing multiple end effect areas in the rotor packing layer by changing the liquid feeding method. This segmental liquid feeding method can be applied to A vertical or horizontal supergravity rotating packed bed belongs to the field of supergravity technology. Background technique [0002] In 1976, Professor Ramshow of the British Imperial Chemical Company was inspired by the experiment that the mass transfer process is almost difficult to carry out under the space microgravity. He developed the concept of hypergravity technology and invented a hypergravity rotating bed (RPB) device that simulates a hypergravity environment. After more than 30 years of research, researchers have carried out a number of basic studies on the high-gravity rotating bed, which has enabled people to have a deeper understa...

AI Technical Summary

Problems solved by technology

In a system requiring longer reaction residence time and higher mass transfer coefficient, limited by the end effect zone, simply increasing the radial thickness of the filler can play a very limited role. Moreover, increasing the radial thickness of the filler will reduce the Increase energy consumption, increase equipment footprint, and affect device stability

At present, the high-gravity rotating bed used in industrial applications and laboratories adopts a single liquid inlet method at the inner edge of the rotor, but due to the influence of the end effect area, most of the fillers outside the end effect area are not sufficiently filled. use of
