Abstract

The invention discloses a multilayer countercurrent rotating packed bed apparatus. The apparatus comprises a closed cylinder shell, a mandrel penetrating through the cylinder shell, and above two rotating packed beds. Each of the rotating packed beds comprises a porous inner ring, a porous outer ring, a cavity limited between the porous inner ring and the porous outer ring, a hollow upper cover and a chassis fixed on the mandrel, and the cavity of each of the rotating packed beds is filled with a solid filling substance. A tubular water diffusion disc is matched with a position above each of the rotating packed beds, and the tubular water diffusion disc comprises a hollow circular ring, a hollow disc and above one water diffusion tube. The hollow circular ring is connected to the hollow disc, the water diffusion tube is connected to a position below the hollow circular ring, and the water outlet of the water diffusion tube is positioned at the inner side of the porous inner ring of each of the rotating packed beds. The multilayer countercurrent rotating packed bed apparatus successfully increases the gas-liquid mass transfer area in order to improve the gas-liquid mass transfer effect.

Description

technical field

[0001] The invention relates to a gas-liquid contact device, in particular to a multi-layer counter-current rotary packed bed, which can be applied to related procedures such as mass transfer between gas and liquid. Background technique

[0002] Hypergravity technology is an innovative technology that strengthens the gas-liquid mass transfer process. It uses the super-gravity environment to increase the specific surface area of ​​gas-liquid contact and reduce the mass transfer resistance between gas and liquid, so as to increase the gas-liquid mass transfer rate and reduce the volume of the reactor. purpose. The main mechanism of supergravity technology is that under the centrifugal acceleration hundreds to thousands of times higher than the earth's gravitational field, the liquid will form tiny droplets, liquid films, and liquid filaments on the surface and pores of the filler. The flow from the inner diameter to the outer diameter not only increases the sp...
