Abstract

The invention discloses a rotating packed bed device with the function of regulating and controlling axial liquid distribution, and belongs to the technical field of supergravity. The device comprises a closed shell; the center of the shell is provided with a rotating shaft which runs through various shell sections; and a packing layer is arranged in a rotor. The axial uniform distribution of liquid can be realized by regulating and controlling the liquid by internal members such as a honeycomb duct type liquid distributor, a point-plane type liquid distributor, a split cylinder type liquid redistributor, a triangular conical ring and the like under the condition of no pump pressure, so that packing in the rotor is fully utilized, the mass transfer effect is strengthened, and the mass transfer efficiency can be improved by 60 to 70 percent. The internal members for regulating and controlling the axial distribution of the liquid can be used on a single-stage or multi-stage rotating bed, particularly rotors of a multi-stage countercurrent rotating bed except a first-stage rotor.

Description

technical field

[0001] The invention relates to a high-gravity rotating bed device capable of regulating and controlling the axial liquid distribution, and specifically relates to some new internal components for improving the axial liquid distribution of the rotor, which can be applied to the high-gravity rotating packed bed of a single-stage or multi-stage rotor, and belongs to the super-gravity The field of gravity technology. Background technique

[0002] In traditional gas-liquid mass transfer equipment such as absorption or rectification, the liquid is evenly sprayed on the top of the packing from the top of the tower through the liquid distributor, and the gas is sent from the bottom of the tower, flows through the gap of the packing, and countercurrently flows with the liquid in the packing layer. Contact for mass transfer. The uniform distribution of the gas-liquid two-phase in the packing layer greatly affects the effect of mass transfer. To this end, the researc...
