Description
Technical field:
The present invention is to the improvement of the desulfurizing tower structure of existing wet desulphurization, particularly discloses a kind of efficient gas-liquid mass transferring device, belongs to the chemical equipment technical field,
Background technology:
At present, the desulfurizing tower of most wet desulphurizations adopts packed tower substantially, because the filler specifications and models that adopt are different, so mass transfer area is different, but design department can both design different tower bodies according to the difference of tolerance size, hydrogen sulfide content what and selected filler in when design, in a word, all can satisfy the production needs, promptly generally can both satisfy the requirement of gas purification degree.Yet, along with the production-scale continuous expansion of enterprise, and the adjustment of postorder product diversification, enterprise requires more and more stricter to desulfurization.And the disadvantage that the filler desulfurizing tower is brought is also more and more outstanding, and tower is done bigger and bigger, and internal circulating load is more and more higher, but degree of purification also more and more can not satisfy the production needs.More seriously, the phenomenon of the stifled tower of packed tower is more and more and serious, has had a strong impact on the ordinary production of enterprise.
Summary of the invention:
The present invention discloses a kind of efficient gas-liquid mass transferring method, has overcome the high shortcoming of material filling type wet desulphurization technical costs.
Shortcomings such as the present invention also provides a kind of efficient gas-liquid mass transferring device, and it is bulky to have solved existing desulfurizing tower, and gas purification degree is low.
Technical solution of the present invention is as follows: gas is directly entered the bubble redistributor from tower bottom, after coming out, the bubble redistributor contacts with the doctor solution bubbling that gets off from overhead streams, hydrogen sulfide in the gas rapidly and desulfurization alkali lye react, gas is with form upwards ascension under buoyancy of vesicle simultaneously, in bubble ascension process, repeatedly increase the bubble apparatus for redistributing, make bubble form countless bubble populations through broken the distribution again, thereby strengthened mass-transfer progress greatly, the removal efficiency of hydrogen sulfide will reach 60-70% this moment, enter second layer distribution apparatus rapidly through the gas after the preliminary purification, finish above-mentioned reaction equally, the gas purification degree of this moment can reach 90-95%, and at last according to the degree of purification requirement, gas enters the 3rd layer of distribution absorption plant and go out tower behind demister.
The following structure of concrete employing: be provided with defoaming plate, liquid distribution trough and multi-stage gas-liquid exchange mechanism in the tower body from top to down, the bottom of tower body is a liquid collecting room, and the top of tower body is the gas outlet; Described gas-liquid exchange mechanism comprises the distribution grid again on top, the bubble redistributor at middle part and the baffle plate of bottom, be evenly distributed with tap hole on the distribution grid again, the bubble redistributor is a cavity structure, the surface distributed round of giving vent to anger, make bubble breaking form bubble population, its breather pipe and next stage gas-liquid exchange mechanism UNICOM, downspout is located between the two gas-liquid exchange mechanisms, the upper orifice of downspout is positioned on the plane of distribution grid again, lower nozzle is located at baffle plate and again between the distribution grid, the downspout of final stage gas-liquid exchange mechanism meets liquid collecting room; Charging aperture and liquid distribution trough UNICOM, the desulfurization lean solution from charging aperture through liquid distribution trough spray and descend, the bubble redistributor UNICOM of air inlet pipe and final stage gas-liquid exchange mechanism, drain pipe and UNICOM of liquid collecting room discharge liquid.
The present invention and the contrast of material filling type wet desulphurization technology, the desulfurizing tower of same scale, according at present general packed tower design, situation is as follows: desulfurizing tower diameter: 3.4m, high 32.50m; Selecting the polypropylene cascade ring is filler, totally 3 layers of fillers, and every layer of filler is high 5 meters, 15 meters of height overalls, 136m altogether
3Solution internal circulating load: 400m
3/ h.This tower will use three layers of redistributor, a liquid distribution trough.Estimate this tower gross investment: 900,000 yuan.
Adopt device of the present invention as the mass transfer internals, then designed desulfurizing tower situation is as follows: desulfurizing tower diameter: 2.2m, high 21.00m; Need not use filler; Solution internal circulating load: 320m
3/ h; Tower is estimated gross investment: 550,000 yuan.
The good effect that the present invention has is: utilized H
2S and aqueous slkali can carry out the feature of chemical reaction fast, adopt gas-liquid directly to contact, and make dynamically contact between the gas-liquid, the turbulence mass transfer, increased the contact area between gas-liquid greatly, made gas in the extremely short time, realize fully mixing and contact, improved the gas cleaning degree with liquid; The present invention solves the stifled tower problem in the filler desulfurizing tower without filler, and apparatus structure is simple, and is easy for installation, and operating flexibility is big, and the tower resistance drop is little, and production cost is low, and practical application effect is remarkable.
Description of drawings:
The specific embodiment:
According to shown in Figure 1, be provided with defoaming plate 5 in the tower body 14 from top to down, (present embodiment is three grades of gas-liquid exchange mechanisms for liquid distribution trough 7 and multi-stage gas-liquid exchange mechanism 15, also can just come to determine to use progression) according to hydrogen sulfide content in the gas, the bottom of tower body 14 is a liquid collecting room 16, described gas-liquid exchange mechanism 15 comprises the distribution grid again 8 on top, the bubble redistributor 9 at middle part and the baffle plate 10 of bottom, be evenly distributed with tap hole 17 on the distribution grid 8 again, bubble redistributor 9 is a cavity structure, the surface distributed round 18 of giving vent to anger, make bubble breaking form bubble population, its breather pipe 19 and next stage gas-liquid exchange mechanism 15 UNICOMs, downspout 11 is located between the two gas-liquid exchange mechanisms 15, the upper orifice of downspout 11 is positioned on the plane of distribution grid 8 again, lower nozzle is located at baffle plate 10 and reaches again between the distribution grid 8, charging aperture 1 and liquid distribution trough 7 UNICOMs, the desulfurization lean solution is descended through liquid distribution trough 7 sprays from charging aperture 1, bubble redistributor 9 UNICOMs of air inlet pipe 2 and final stage gas-liquid exchange mechanism 15, drain pipe 3 is discharged liquid with 16 UNICOMs of liquid collecting room, and the bottom of tower body 14 also is provided with discharging tube 13.
