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

Abstract

The invention relates to a rotating bed of overweight field of baffled gas-liquid cross flowing type. The shell of the invention is divided into an upper cavity and a lower cavity by a static disc; a gas outlet and a liquid inlet are respectively communicated with the upper cavity; the gas inlet and liquid outlet are respectively communicated with the lower cavity; a rotary shaft goes through the shell; the rotor consists of an upper movable disc, a lower movable disc, a concentric circle of the lower movable disc, a short concentric circle, a long concentric circle and a liquid distributor which are fixedly connected with the rotary shaft, wherein, the upper movable disc is provided with the slots for gas circulation; the long concentric circle is arranged between the upper movable disc and the static disc; the long concentric circle and the short concentric circle are crossly positioned; a first passage and a second passage are communicated through the upper movable disc slot to form a devious S-shaped baffled passage; the upper concentric circle and the lower concentric circle are provided with the small holes corresponding to the liquid outlet holes on the liquid distributor in axial direction; one end of a liquid guide pipe is communicated with the upper end of the liquid distributor while the other end with liquid inlet. The invention has the advantages of excellent mass transfer capability which reduces the rotational energy consumption and 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
