Description
Technical field
The present invention relates to a kind of hypergravity swinging bed device that the regulation and control axial liquid distributes that has, be specifically related to the novel inner member that some improve the rotor axial liquid distribution, can be applicable to the high gravity rotating packed bed of single-stage or multi-stage rotor, belong to the high-gravity technology field.
Background technology
In the gas-liquid mass transfer (contact) equipments such as traditional absorption or rectifying, liquid evenly is sprayed on the top of filler through liquid distribution trough from cat head, and gas is sent at the bottom of tower, flows through the space of filler, contacts with liquid countercurrent in packing layer and carries out mass transfer.Whether gas-liquid two-phase has affected the effect of mass transfer greatly in the even distribution of packing layer.For this reason, the researcher is divided into some sections with filler, developed the plurality of liquid redistributor and placed in the middle of the packing section, the regulation and control gas-liquid two-phase in tower on the cross section evenly, thereby reduce wall stream etc. to the impact of mass transfer.
The high-gravity technology that grew up in 1976, as a kind of reinforcement gas-liquid mass transfer (contact) equipment, its core apparatus is high gravity rotating packed bed.Packed bed inside is a High Rotation Speed rotor of filling filler, its centrifugal acceleration be acceleration of gravity 30-1000 doubly, liquid contacts with back flow of gas under huge centrifugal force drives and finishes gas-liquid mass transfer.The high-gravity rotating bed centrifugal force field of utilizing is simulated super gravity field, and its core is the very big reinforcement to transmittance process and micro mixing.Along with developing rapidly of high-gravity technology, (see for details Chinese patent 92102061,95105344.2,200710120712.7,200810103231 etc.) obtained application to high-gravity technology in fields such as oil-field flooding deoxidation, ultramicro powder preparation, polymer devolatilization, collecting carbonic anhydride, rectifying.
As the gas-liquid mass transfer (contact) equipment that loads a small amount of filler, high gravity rotating packed bed also exists gas phase and liquid phase in the equally distributed problem of packing layer.Generally speaking, gas phase can guarantee that evenly passing packing layer flows out from gas vent substantially after gas feed enters the revolving bed cavity, and what emphasis need to be paid close attention to is the even distribution problem of liquid phase.In before high-gravity rotating bed, liquid at the liquid distribution trough force fluid that enters even perforate under the effect of pump pressure in the even distribution of packing layer on axially.At the multi-level countercurrent high-gravity rotating bed (seeing Chinese patent 200920247008 for details) of nearest utility model patent report when carrying out distillation process, find that the biggest problem that this revolving bed faces is that liquid flows down by first order inner chamber along inwall and collects when flowing to the next stage rotor after first order rotor (top layer rotor) throws away on the revolving bed cavity inner wall, liquid the next stage rotor axially on liquid distribute again very inhomogeneous, thereby weakened the mass transfer effect of next stage rotor.Next stage rotor liquid axial distribution is than the reason of first order rotor liquid axial distribution weak effect: first order rotor liquid is evenly to be ejected into from liquid distribution trough under the effect of pump pressure on the rotor inner edge, and even perforate or the liquid distribution trough force fluid that cracks are evenly distributed in the axial direction.When liquid flows to the next stage rotor, liquid fully by gravity from the marginal flow of last layer inner chamber catch tray on the rotor inner wall of next stage High Rotation Speed, caused liquid at rotor packing layer skewness.It is insufficient that the liquid consequence that skewness brings on the next stage rotor axial will make the rotor filler utilize, and mass transfer effect has weakened.
