Description
Technical field
The utility model relates to a kind of gas-liquid contact mass transfer equipment, refer in particular to a kind of flow turning-back gas liquid cross-flow super-gravitational field revolving bed device, can be widely used in the occasions such as absorption, rectifying, heat transfer, chemical reaction and nano material preparation of industries such as chemical industry, pharmacy, metallurgy, light industry, owing to the path that has prolonged gas phase is particularly useful for gas absorption process.
Background technology
After being born eighties of last century seventies, high-gravity technology enjoys favor owing to the volume of reduction equipment greatly.Granted patent about high-gravity technology is the patent EP0002568 of Ramshaw professor in Europe the earliest, patent name is Mass transfer apparatus and itsuse, a kind of material filling type hypergravity field swinging bed (rotary packed bed) is disclosed, the patent such as the ZL97212054.8 of a lot of thereafter high-gravity technologies, CN95214611.8 etc. belong to this typical structure, the kind of different just fillers and the mode of gas-liquid turnover.Rotary packed bed commercial the earliest the application is absorption process (the Smelser et al.Selective acid gas removal using the HIGEE absorber.AIChE Spring Meeting that is used for sour gas in the report, Orlando, Florida.1990,18), still the rotary packed bed absorption process that is applied to has the defective of himself.Because the rotation of the high speed of rotor, gas-liquid two-phase is very short time of contact in bed, though therefore gas-liquid mass transfer efficient is very high, the mass transfer ability of single rotor is relatively still limited, and this is disadvantageous for the GAS ABSORPTION of intermediate concentration.Because the mass transfer of single rotor is limited in one's ability, therefore the higher occasion of mass transfer Capability Requirement is just needed a plurality of rotors, but do not see the report of a plurality of filler rotors of series connection in the single housing in the disclosed so far patent as yet on the other hand at some.
Patent ZL01134321.4 and ZL200510049145.1 disclose a kind of deflection of jet type revolving bed equipment in hyper gravity field of a plurality of rotors of can connecting in single housing, owing to adopted the structure of sound parts combinations, make it can realize the series connection of multi-layer rotor simply, make the mass transfer ability of single device improve exponentially.Though this revolving bed has higher mass transfer ability, also exist the weakness of self, because rotor has adopted the structure of sound parts combinations, liquid has experienced static-accelerator repeatedly in rotor, so the energy consumption of rotor rotation is higher; On the other hand, be non-mass transfer zone because internal rotor has a half space, so gas is little in the circulation area of internal rotor, the resistance of gas in rotor is bigger, so this equipment gas pressure drop is bigger.In addition, the internal rotor of rotating zigzag high-gravity bed exists mass transfer and non-mass transfer zone, so the space in the rotor fails effectively to utilize, thereby its gas-liquid flow is less relatively under the identical device volume conditions.
The utility model content
The utility model proposes the flow turning-back gas liquid cross-flow super-gravitational field revolving bed device of a kind of comprehensive above-mentioned existing advantage, the above-mentioned existing shortcoming of solution.It is higher that this device has the mass transfer ability, rotate energy consumption and the lower characteristics of pressure drop, its gas phase is walked baffling, flow path is longer relatively, liquid phase radial flow in rotor is crossed each concentric turns, can be applicable to gas absorption process preferably, and this structure can realize the many rotor coaxial series connection in the mono-hull easily.
The technical scheme that its technical problem that solves the utility model adopts is: this flow turning-back gas liquid cross-flow super-gravitational field revolving bed device, mainly comprise housing, gas feed, gas vent, catheter, liquid distribution trough, liquid-inlet, liquid outlet and rotating shaft, housing is divided into upper cavity and lower chamber by quiet dish, housing be provided with gas feed, liquid outlet, gas vent and liquid-inlet, wherein gas vent, liquid-inlet communicate with upper cavity respectively, and gas feed, liquid outlet are connected with lower chamber respectively; Rotating shaft runs through housing, rotor is by the last Moving plate of fixedlying connected with rotating shaft, following Moving plate, following Moving plate concentric turns, short concentric turns, long concentric turns, liquid distribution trough is formed jointly, wherein go up the last Moving plate slotted eye that has the supplied gas circulation on the Moving plate, be provided with long concentric turns between last Moving plate and the quiet dish, the junction is provided with labyrinth seal between long concentric turns and the quiet dish, long concentric turns is staggered with short concentric turns, and by short concentric turns, long concentric turns, last Moving plate and quiet dish constitute first passage, by last Moving plate, following Moving plate and following Moving plate concentric turns formation second channel, first passage and second channel are connected by last Moving plate slotted eye and form the S shape baffling passage of complications; Last concentric turns and following concentric turns are axially having aperture with the relative position of the fluid hole of liquid distribution trough; Gas feed and liquid outlet are connected with the S shape baffling passage of rotor, and an end of catheter is connected with the liquid distribution trough upper end, and the other end is connected with liquid-inlet.Liquid is introduced rotor by liquid-inlet through catheter, liquid is finally to leave rotor by progressively passing through the aperture of each concentric turns again behind the liquid distribution trough earlier in rotor, finally leaving the outer cause liquid outlet of rotor discharges, gas tangentially enters housing by gas feed, by leaving rotor from the centre behind the S shape baffling passage, discharge by gas vent at last circuitously.Such structure makes the interior gas of rotor repeatedly to carry out cross-flow with liquid and contacts.
Described housing is divided into upper cavity, multilayer middle chamber and lower chamber by quiet dish, and middle chamber is provided with the intermediate feed mouth, forms multilayer baffling structure, realizes a plurality of rotor coaxial series connection easily, improves the mass transfer ability of single device exponentially.
The beneficial effects of the utility model are: 1, rational in infrastructure, because there is not non-mass-transfer zone in the radial extension in the rotor, so space utilization is abundant in the rotor.2, can be provided with multi-layer rotor in the housing, the mass transfer ability of single device significantly improves.3, compare with ZL200510049145.1, under the identical prerequisite of moving-coil quantity, because the gas flow area will be twice in the rotor, air resistance is less in the rotor, so pressure drop is lower.4, because liquid only experiences the process of progressively quickening in rotor, therefore the energy consumption of rotating reduces significantly.
