Abstract
The present invention relates to a two-direction inner circulation gas and liquid high-efficiency contactor for the contact of gas and liquid, which has a structure that a centrifugal blower is arranged in the contactor; gas at the upper half part of the contactor can move along a catheter from top to bottom and can move through distribution holes from bottom to top; meanwhile, a centrifugal pump arranged in the contactor absorbs liquid at the lower half part of the contactor from bottom to top and sprays out the liquid by a nozzle of the catheter; the sprayed liquid falls down from top to bottom because of self-gravity to form two-direction gas and liquid movement; thus, the contact effect of gas and liquid is enhanced greatly.
Description
The present invention relates to the device that gas-liquid two-phase mixes contact, particularly in the still of discontinuous, carry out gas-liquid two-phase and carry out from up to down fully mixing the device that contacts with bottom-up flowing.
The contact of the mixing of gas-liquid two-phase in the prior art is widely used in chemical industry and other field.Reaction of for example gas absorption operation, gas-liquid phase chemistry and gas-liquid biphase equilibrium etc. can divide three kinds of batch (-type), semi continuous and continous ways by mode of operation.Gas-liquid two-phase is non-current phase in batch (-type), and in semicontinuous, gas phase is the phase that flows usually, and liquid phase is non-current phase, in continous way, two-phase is mobile phase, and two keys that contact are sizes of contact surface, at any time upgrade contact-making surface, existing various forms of mixing contactors, for example:
1. the batch still that adds stirring;
2. the semicontinuous and continuous still (tower) that adds the gas phase distribution grid;
3. the continuous tower that adds spray thrower;
4. be with the packed tower of gas phase distribution grid, liquid phase spray thrower.
Two-phase fluid all is that the contact area and the time of contact of acyclic two-phase are restricted in the above-mentioned various device.At US-5,009, in 816,, make gas phase be in the recurrent state liquid phase and still can not circulate though improved impeller suction line is housed on shaft, its contact effect is still not high, the present invention adopts gas-liquid two-phase to carry out the efficient contact device of interior circulation, can increase the contact area of gas-liquid two-phase widely, and can regulate the time of contact of two-phase effectively, thereby improved the contact effect of two-phase, increased the production intensity of the various device that relates to the gas-liquid two-phase contact.
Below in conjunction with accompanying drawing and concrete performance the present invention is elaborated.
Fig. 1 is the sketch of two-direction inner circulation gas liquid contactor of the present invention.Wherein:
1. centrifugal blower, 2. suction line, 3. blower fan discharge pipe, 4. gas distributor, 5. blower fan suction inlet, 6. centrifugal pump, 7. liquid suction line, 8. centrifugal pump suction inlet, 9. liquid outlet tube, 10. sprayer unit, 11. lower shafts, 12. shaft couplings, 13. water cooling plant, 14. magnetospheres, 15 belts, 16. lids, 17. flange hole, 18. body housings, 19. sleeve pipes, 20. fixed heads, 21. fastening bolt, axle on 22., 23. liquid levels.
Fig. 2 is the A-A profile.
Fig. 3 is the B-B profile.
Fig. 4 is the C-C profile.
The present invention is a kind of mixing contactor of gas-liquid phase, it is characterized in that adopting two-way internal circulation apparatus, in contactor, be provided with centrifugal blower, make the gas at the first half place of contactor inside upward discharge gas from descending through subsurface gas distributor again along the blower fan discharge pipe from top to down; Be provided with centrifugal pump in the contactor, the liquid at the inner Lower Half of contactor place can along liquid outlet tube from down and on sprayer unit spray liquid more than liquid level, and the liquid power of can relying on for support falls from top to down.
Now be described as follows, as shown in Figure 1, suck from centrifugal blower suction inlet 5 at gas reactor, enter centrifugal blower 1 by suction line 2, gas increases pressure in air blast after, arrive gas distributor 4 from top to bottom through blower fan discharge pipe 3, this distributor is positioned at the still bottom, but should be higher than centrifugal pump suction inlet 8 certain distances, and distributor 4 is made up of the inside and outside pipeloop that communicates, there is the oblique aperture of 4 rows on the surface thereon, shown in the C-C cross section of Fig. 4, minute bubbles can stir (rotation) liquid effectively from the oblique ejection of aperture, and constantly rise, enter gas phase after being incorporated in the liquid layer skin breakage, because of the liquid layer surface pressing is higher than blower fan suction inlet place, gas moves upward, constitute top-down positive motion of gas and proper motion from bottom to top, form the gas phase circulation.
Liquid is sucked by centrifugal pump suction inlet 8 among the present invention, arrive centrifugal pump 6 through liquid suction line 7, liquid in pump, pressurize the back from liquid outlet tube 9 to sprayer unit 10, upwards be the back taper ejection, the collision upwards time of the drop of ejection becomes big, part reaches vessel surface and internals surface and flows downward, the part drop falls to reaching the liquid layer surface voluntarily behind certain altitude, so just formed liquid positive motion and top-down proper motion from bottom to top, constitute the liquid phase circulation, the key that forms the liquid phase circulation is that centrifugal pump runs well, and prevents to suck gas at suction inlet 8.
Centrifugal pump in apparatus of the present invention and centrifugal blower couple together axle 22 with shaft coupling 12 with lower shaft 11 and last axle 22 and pass blower fan suction line 2, and suction inlet 5 is connected with turning cylinder, and power transmission shaft can be with two kinds of methods drivings, at high pressure such as 6kg/cm
2When more than operating, for preventing to leak, available Electromagnetic Drive shown in Figure 1 15 is a driving belt, and 14 is magnetosphere, and its inside is the axle soft made of iron that is connected with axle, and 13 is water cooling plant; Not high at pressure as 6kg/cm
2When following, can directly use motor-driven, rotate for preventing blower fan and pump case, be fixed on the sleeve pipe 19 with the suction line of fixed head 20 with them, sleeve pipe 19 can insert thermometer again, measures temperature.
As for described Electromagnetic Drive, what generally be applicable to mini-plant is 123W as Dalian the 4th FYX-1 of instrucment and meter plant type motor.The 40W of the adopted Shanghai micromachine factory of motor direct-drive, 2800 rev/mins monophase machine, centrifugal blower be for generally general, the outlet blast be 300～1500 millimeters of water just can, centrifugal pump also is a plain edition.
From the contrast experiment, in common intermittent operation, if the diameter of blender is 0.3m, high 0.9m, empty G﹠W contact, the water layer height is 0.45m, stirs as adopting the slurry formula, the contact-making surface of two-phase only is 0.16m
2, adopt the present invention then to can be 54.77m
2(amount of air circulation is 0.015m
3/ s, the water internal circulating load is 0.0005m
3/ s.
In the continous way operation, the diameter of blender is 0.3m, and height is 1.2m, adopts filler and bubbling two-layer, and the contact area of two-phase only is 15.9m
2, adopt the present invention then can reach 174.63m
2
The advantage of device of the present invention has provided three kinds of gas-liquid two-phase contact-making surfaces, the one, contacting of bubble and liquid level is present in liquid level, and the 2nd, the contacting of drop and gas, contacting of liquid film and gas, be present in gas blanket and centrifugal blower and suction thereof, the discharge pipe place, and owing to suck in the gas with droplet, under the effect of fan blade, drop is pulverized, and contact surface increases also and upgrades, and the 3rd, broken from the below bubble and brought in constant renewal in from the set of top drop in the gas-liquid interface place. Thereby the contactor that the contact that makes gas-liquid two-phase reaches than prior art has higher effect.
The present invention has device to change a little also to can be used for the gas-liquid contact, and its method is to change centrifugal blower into centrifugal pump, and former centrifugal pump outlet shower nozzle changes the heavy phase distributor in the liquid phase into, just can realize.
