Concentric ring type cross current type hypergravity field swinging bed device

Abstract

The invention relates to concentric cross-flow type rotating packed bed in high-gravity field , comprising a shell, a rotating disc, a rotating shaft and a liquid redistributor, the shell is provided with a medium a inlet pipe, a medium b outlet pipe, a medium d outlet pipe and a fluid bath, a concentric ring and the liquid redistributor are fixedly connected with the rotating disc, the center of which is in fixed connection with the rotating shaft, the end of labyrinth seal is in connection with the shell, the lower end is in connection with a guiding pipe which is inserted in the fluid bath, the labyrinth seal and the rotating disc divide the shell into an upper cavity and a lower cavity, the medium b outlet pipe is in communication with the upper cavity, the medium a inlet pipe and the medium d outlet pipe are separately in communication with the lower cavity, one end of a medium c inlet pipe is in communication with the upper end of a liquid distributor, while the other end surpasses the shell and is sealed together with the shell. The beneficial effect of the rotating packed bed is that the rotating packed bed of the invention has the simple and reasonable structure so as to be easily installed, the little gas resistance, the low equipment pressure drop, and the higher efficiency and the better effect of gas-liquid mass transfer.

Description

technical field [0001] The invention relates to a gas-liquid contact device, especially a concentric circle cross-flow type supergravity field rotating bed device, which can be widely used in gas-liquid contact in chemical industry, petrochemical industry, biochemical industry, pharmaceutical, metallurgy, light industry and other industries Occasions, especially suitable for desorption, heat exchange, reaction process. Background technique [0002] The high gravity field rotating bed is characterized by small size and high mass transfer efficiency, and is known as the "transistor" of chemical equipment. Before the present invention was made, the high-gravity field rotating beds in the prior art could be divided into two categories according to the rotor structure: single-layer high-gravity field rotating beds and multi-layer high-gravity field rotating beds. The single-layer high-gravity field rotating bed has packing type Chinese patents CN1059105A, CN1062098A, disc type C...

AI Technical Summary

Problems solved by technology

Although the current packed high-gravity field rotary bed has a relatively large processing capacity, the mass transfer efficiency is not high enough because there is only one rotor, and the gas phase flow resistance is large, and the equipment pressure drop is large, so it is not suitable for larger flow rates and mass transfer. Higher requirements for gas-liquid heat and mass transfer occasions; and the baffled high-gravity field rotating bed, although the mass transfer efficiency is higher, but the gas takes an "s"-shaped curved channel, and it must overcome physical resistance, and the gas phase flow resistance is large , The pressure drop of the equipment is large, and it is not suitable for large flow gas-liquid heat and mass transfer
