Flow turning-back gas liquid cross-flow super-gravitational field revolving bed equipment

Abstract

The invention relates to a baffle type gas-liquid cross-flow type supergravity field rotating bed device. The shell is divided into an upper cavity and a lower cavity by a static plate. The outlets are respectively connected with the lower cavity; the rotating shaft runs through the housing, and the rotor is composed of an upper moving plate, a lower moving plate, a concentric circle of the lower moving plate, a short concentric circle, a long concentric circle and a liquid distributor which are fixedly connected to the rotating shaft. There is an upper rotor slot on the upper rotor for gas circulation. There are long concentric circles between the upper rotor and the static disc. The long concentric circles and short concentric circles are arranged alternately. The first channel and the second channel pass through the upper rotor. The disc slots are connected to form a tortuous S-shaped baffle channel; the upper concentric circle and the lower concentric circle have small holes in the axial direction opposite to the liquid outlet hole of the liquid distributor, and one end of the catheter tube is connected to the liquid distributor. The upper end of the device is connected, and the other end is connected with the liquid inlet. The beneficial effects of the invention are: high mass transfer capacity, low rotational energy consumption and reduced pressure.

Description

technical field [0001] The invention relates to a gas-liquid contact mass transfer device, in particular to a baffled gas-liquid cross-flow type supergravity field rotary bed device, which can be widely used in chemical, pharmaceutical, metallurgy, light industry and other industries for absorption, Occasions such as rectification, heat transfer, chemical reaction, and preparation of nanomaterials are especially suitable for gas absorption processes due to the extended path of the gas phase. Background technique [0002] Since its birth in the 1970s, hypergravity technology has been favored because it can greatly reduce the size of equipment. The earliest authorized patent on high-gravity technology is Professor Ramshaw's European patent EP0002568, the patent name is Mass transfer apparatus and its use, which discloses a packing type high-gravity field rotating bed (rotating packed bed), and many high-gravity technology later Patents such as ZL97212054.8, CN95214611.8, etc....

AI Technical Summary

Problems solved by technology

Although the rotating bed has a high mass transfer capacity, it also has its own weaknesses. Because the rotor adopts a structure combining dynamic and static parts, the liquid has experienced multiple static-acceleration processes in the rotor, so the energy consumption of the rotor rotation On the other hand, since half of the space inside the rotor is a non-mass transfer area, the flow area of ​​the gas inside the rotor is small, and the resistance of the gas in the rotor is large, so the gas pressure drop of the equipment is large

In addition, there are mass transfer and non-mass transfer areas inside the rotor of the baffled high-gravity field rotating bed, so the space in the rotor is not effectively utilized, so the gas-liquid flow rate is relatively small under the same equipment volume conditions
