The specific embodiment
Provide preferred embodiment of the present invention below, these embodiment and unrestricted content of the present invention.
Embodiment
The core component of rotating zigzag high-gravity bed is the rotor of being association of activity and inertia; Some concentric turns are fixed on the moving baffling circle crowd of formation on the Moving plate; Drive its rotation by rotating shaft; With moving baffling circle relatively and with its nested installation directly be fixed on the quiet baffling circle crowd that is on the stationary disk, its structure is as shown in Figure 1.
Its operation principle is: the gas as continuous phase gets into housing by gas inlet pipe 2; Under the effect of pressure reduction; From the rotor outer rim along Jing Zheliuquan and the gap between the moving baffling circle flow by export-oriented center from coil to coil circuitously, after gas outlet tube 5 leaves a body; As the liquid of decentralized photo get into by liquid feed pipe 6 and by drainage to the Moving plate center, got rid of repeatedly to Jing Zheliuquan by the moving baffling circle of a series of high speeds rotations subsequently, in housing, collect the back at last and draw by liquid outlet tube 9.Liquid phase has experienced the repeatedly process of dispersion-gathering betwixt; In this process; Liquid throws away moving-coil with extremely trickle drop; The drop of high-speed motion on Jing Quan by collision, shear and splash, under the effect of rotation gas centrifugation power, formed specific area greatly and the gas-liquid interface of bringing in constant renewal in, therefore have high mass transfer rate.Compare with the traditional tower under the gravitational field, rotating zigzag high-gravity bed has the characteristics that conventional hypergravity field swinging bed (material filling type or disc-type etc.) are had equally, and mass-transfer efficiency is high; Equipment volume is little, and the time of staying is short, and liquid holdup is little; Anti-stifled ability is strong; The start-stop appearance of vehicle is prone to, and is applicable to the processing of valuable material, heat sensitive material, high-viscosity material or poisonous material, can use in height, two-by-twice occasion.But compare with the hypergravity field swinging bed of routine, in industrial distillation operation, rotating zigzag high-gravity bed structurally has more significant advantage:
(1) rotating zigzag high-gravity bed has only following disc spins; Last dish is static, has solved moving and quiet contradiction dexterously, has saved the movable sealing between rotor and the gaseous phase outlet; Every device just 1 place movable sealing (being the movable sealing between rotor and the housing) has reduced the manufacture difficulty of equipment.And the upper lower burrs of conventional hypergravity field swinging bed fixedly filler is all rotated, and flows through rotor for guaranteeing gas, needs the movable sealing of 2 places, thereby and goes up movable sealing and directly contact the perishable life-span that influences equipment with medium.
(2) the upward dish of rotating zigzag high-gravity bed is static, can in the optional position of last dish charging aperture be set easily, thereby can realize the continuous rectification process.And conventional hypergravity field swinging bed because the whole rotation of rotor can't realize intermediate feed, must 2 revolving beds polyphones could be realized the intermediate feed of continuous rectification, make the flow process complicacy like this, the equipment investment increase.
(3) rotating zigzag high-gravity bed does not need the original liquid distributor, and the anti-clogging ability is strong.And the conventional hypergravity field swinging bed original liquid distributor that needs, otherwise because the inhomogeneous meeting of liquid distribution reduces mass-transfer efficiency greatly.
(4) prolongation that the tortuous passageway of rotating zigzag high-gravity bed " S " type is suitable gas-liquid contact time, help the raising of mass-transfer efficiency.And conventional hypergravity field swinging bed diameter limited (receiving dynamically balanced restriction); Although gas-liquid mass transfer has high speed in the rotor; But because gas-liquid contact time is extremely short, the separating power of single device is restricted, can not satisfies the requirement of conventional organic matter rectifying separation.
(5) rotating zigzag high-gravity bed can be in same housing be installed multi-layer rotor easily on same axle, and the number of theoretical plate of single device is improved exponentially, and Fig. 2 is the structural representation of the rotating zigzag high-gravity bed of three layers of rotor.And the conventional hypergravity field swinging bed series connection that will realize rotor then must use the equipment more than 2 to accomplish.
It is hydrodynamic performance and the mass-transfer performance that system is measured that Fig. 3～Fig. 5 has provided with air-water and alcohol-water.Every pair of sound baffling circle pressure drop of rotating zigzag high-gravity bed increases with the increase of gas phase loading factor F and rotating speed, but descends with the increase of liquid spraying density L earlier, and is constant basically subsequently.Under the normal operating condition; The pressure drop of every block of column plate of the traditional plate column under the every pair of sound baffling circle pressure drop and the gravitational field is close; But under same sprinkle density; Operation gas phase loading factor F but wants force of gravity traditional tower after the match much bigger, and does not have tangible pressure drop turning point, and promptly rotating zigzag high-gravity bed has greatly improved liquid flooding gas speed.Can find out that from Fig. 5 under the infinite reflux condition, when less gas, liquid flux, the mass-transfer efficiency of every pair of sound baffling circle has more significantly with the increase of gas, liquid flux and descends, but at gas phase loading factor F greater than 3m/s (kg/m3)
0.5Basically do not become afterwards, thereby shown the baffle type revolving bed good operating flexibility that has with gas, liquid flux.But the rotary speed of rotor has bigger influence to number of theoretical plate; Below 1000r/min; Number of theoretical plate increases with the increase of rotating speed, and at rotating speed during greater than 1000r/min, mass-transfer efficiency changes not quite with the increase of rotating speed; Take all factors into consideration factors such as machine-building and dynamic balancing, the baffle type revolving bed operation rotating speed of commercial Application is about 1000r/min.Radially effective length so that gas, liquid pass through is calculated; At rotating speed is 1000r/min; The infinite reflux amount is under the condition of 600L/h; It can reach the separating power of every meter 20 number of theoretical plates, and diameter is 830mm, highly is merely that three layers of 018m are baffle type revolving bed to reach 15～20 theoretical plates, can satisfy the requirement that conventional organic matter rectifying separation is purified.
In alcohol-water rectifying, methanol-water rectifying application example, accomplish under the identical output and product quality premise, deflection type overgravity rotary bed and traditional packed tower has been carried out the comparison of height and volume, the result sees table 2.
The deflection type overgravity rotary bed comparison with the packed tower equipment size of table 2
Table2?The?size?comparison?of?ZRB?and?packed?column
Appropriate authority has carried out the test of energy consumption to methanol-water continuous rectification system under normal operating condition simultaneously, and the result sees table 3.
Table 3 energy consumption testing result
Table3?The?results?of?power?test
Remarks: test has comprised recirculated cooling water power consumption, and manufacturer's steam price is 130 yuan/T, and the electricity price lattice are 0.5 yuan/kWh
Can be known that by table 2 and table 3 device height drops to 1/16.4 and 1/13.8 of packed tower respectively, volume-diminished is to 1/4.1 and 1/7.2 of packed tower, and what unit methyl alcohol finished product was consumed can be merely 135.71 yuan/ton.It is thus clear that the deflection type overgravity rotary bed mass transfer of greatly having strengthened between gas-liquid can reduce tower and ancillary investment and energy consumption.
Commercial production fully shows; The housing height is that the separating effect of rotating zigzag high-gravity bed of 0.8m is suitable with more than 10 meter high packed tower, and the not enough 2m2 of the floor space of equipment, has reduced the size of production equipment significantly; Reduce the land used of factory, increased the security of producing.Equipment is installed in the building of individual layer and just can operates operation.The test result of appropriate authority shows that this equipment has characteristics such as performance is good, efficient is high, energy consumption is low, volume is little, is a kind of miniaturization gas-liquid mass transfer (contact) equipment of the resource-conserving that is worthy to be popularized.
