The novel rotor is simple in structure, light in weight of the rotating part, low in integral pressure, low in device operation energy consumption, obvious in energy saving and consumption reduction, and particularly suitable for a rapid gas-liquid absorption (such as gas purification) reaction process under high load, especially a gas-liquid reaction process under a low partial pressure gas mass condition.
Description
Technical field
The utility model relates to a kind of rotary packed bed rotor of multilayer strengthened gas-liquid mass transfer, belongs to the rotary packed bed technical field of hypergravity.
Background technology
High-gravity rotating bed is a kind of equipment that new development is got up, particularly more in the application of two-phase haptoreaction, compares with routine techniques, and rotating bed reaction equipment has the advantages such as mass transfer intensity is high, equipment volume is little, liquid holdup is little, spotting out is high, difficult obstruction.
Revolving bed mass transfer reaction process mainly completes in rotor, and rotor filler type development is at present varied.Current commonplace employing be axially or stacked twine or the video disc of adding of radial layer, as the axial concentric sheets filler rotor of patent CN2229833Y announcement, axially parallel web plate filler rotor that CN101234260A announces etc., the type filler generally can only be brought into play bed radially or radially and circumferentially act on, and can not effectively utilize the overall space of rotor.
More conventional traditional gas-liquid mass transfer tower is different, and high-gravity rotating bed have " end effect district ".So-called " end effect district ", referring to will be far away higher than filler inside in the mass transfer intensity in a bit of region of rotor filler inner edge." end effect district " produces is mainly owing to just having entered in filler when liquid, and between liquid and filler, speed different (comprising size and Orientation) produces, and liquid and filler relative velocity are larger, and " end effect " acts on all the more obvious, and mass transfer intensity is higher.Therefore, improving relative velocity between liquid and filler is to improve " end effect " effect effective way.
The rotary packed bed rotor that CN2654194Y announces, filler layering is installed, it is except ground floor filler, because the relative velocity of liquid and filler rotating speed is less, therefore " end effect " acts on not obvious, effect of mass transmitting is not almost brought into play in ring-like gap between filler simultaneously, causes on rotor space and wastes.Utility model patent 2004420092277.3 is announced a kind of filler axial stratification rotor is installed, and in this rotor, gas-liquid is and flows contact, and only in every layer of filler inner radius performance " end effect " simultaneously, cross-flow mass transfer is high not as good as countercurrent mass transfer intensity.The gas-liquid of CN10186776A announcement multilayer strengthened reverse-flow rotary packed bed hypergravity machine ，Dan upper strata filler be take parallel type as main, and mass transfer intensity reduces greatly.Therefore, at present rotor has been brought into play rotary packed bed " end effect " effect in design to a certain extent, but " end effect " effect in gas-liquid mass transfer needs further strengthening, meanwhile, and should be more abundant in the utilization of rotor overall space.
Summary of the invention
In order to overcome the deficiencies in the prior art, the requirement for the reaction of gas-liquid fluid-mixing to equipment high efficiency mass transfer, in conjunction with high-gravity rotating bed own characteristic, the utility model provides a kind of rotary packed bed rotor of multilayer strengthened gas-liquid mass transfer.
A rotary packed bed rotor for gas-liquid mass transfer, by rotation, static two parts form, rotating part by rotating disc, ring-like cover plate and be installed on rotating disc and ring-like cover plate between media assemblage; Stationary part is comprised of the stationary disk being fixedly connected with hypergravity apparatus casing and the liquid deflecting plate that is fixed on stationary disk;
Rotating part adopts the filler of the monolithic devices metal with 3 D stereo intercommunicating pore structure; Filler is shaped as the different concentric circles ring body of diameter, along rotor radial layering arranged side by side, installs;
Liquid deflecting plate is along rotor radial, interts and is installed between the ring-like gap of filler, and liquid deflecting plate upper end is welded on stationary disk, between liquid deflecting plate and adjacent two-layer filler and lower floor's rotating disc, is spaced apart 2～4mm;
Between every layer of ring-like cover plate of rotating part and stationary disk, take thin-skinned contact of line to rotate individual layer or double-layer seal;
The rotating shaft of rotary body is fixedly connected with rotating disc, and hypergravity apparatus casing connects stationary disk, and filler radial thickness is between 50～100mm, and radially layered is installed, and has between layers gap;
Filler lower end is fixed on rotating disc, and filler upper end is fixed on ring-like cover plate, between ring-like cover plate and stationary disk, has rotary seal; In ring-like gap, be provided with between the layers the liquid deflecting plate being fixed on stationary disk; Feed liquor pipeline is connected in exhaust outlet, and exhaust outlet is positioned at the middle part of hypergravity apparatus casing, and air inlet, leakage fluid dram are connected on hypergravity apparatus casing.
In filler radially layered is installed basic Shang， annular domain, be radially provided with liquid deflecting plate, every layer of liquid deflecting plate quantity can be determined according to the size in ring-like gap.
Employing has silk screen, disc-type filler or the deflector type orifice plate of the alternative conventional stacking of monolithic devices filler of three-dimensional communication pore structure.
Between the ring-like cover plate in filler upper strata and stationary disk, take rotary seal.
The artificial creation of construction rotor of the present utility model a plurality of efficient " end effect districts ", particularly liquid deflecting plate is installed on stationary disk and designs, keep relative high-speed motion with filler and liquid, not only strengthen ring-like space inner transmission matter, change the direction that liquid enters lower floor's filler simultaneously, increase the relative velocity (direction of flow rate of liquid and filler rotating speed) between liquid and lower floor's filler, performance " end effect " effect more.Simultaneously, particular fillers design, realized fluid in filler in regular runner radially, axially, circumferential high-efficiency turbulent flow, in a kind of filler, realize simultaneously gas-liquid adverse current, cross-flow, and the form such as stream contact, make full use of filling space, improve to greatest extent the effective contact area of fluid-mixing, strengthening mass transfer.Rotary seal.Because every layer of filler relative thickness is less, gas pressure drop after every layer is very little, therefore, between the ring-like cover plate in filler upper strata and stationary disk, takes to take the simple soft sealing that contacts, simple and convenient.
The utility model has the advantages that the whole bed pressure drop of rotor reduces greatly, is only 1/4～1/3 of conventional rotor, and rotating part light weight, is only routine 1/3～1/2, and rotation energy consumption is low.This rotor is not only conducive to react under low-pressure gas condition, and has further improved the whole mass-transfer efficiency of rotor, reaches multilayer strengthened gas-liquid mass transfer object, and has obviously energy-saving and cost-reducing feature.
This new type rotor structure is simple, rotating part light weight, whole pressure drop is low, and device operation energy consumption is little, has obviously energy-saving and cost-reducing advantage, the Quick gas-liquid being specially adapted under high load capacity absorbs (as gas purification) course of reaction, the gas-liquid reaction process under especially low dividing potential drop makings condition.
