Description
Technical field:
The utility model is the improvement to the packed tower of original wet desulphurization and tubular type bubble tower structure, particularly discloses a kind of quick turbulence type desulfurizing tower, belongs to the chemical equipment technical field.
Background technology:
At present, domestic most popular pressurization desulfurizing tower adopts material filling type desulfurizing tower and small part tubular type bubbling desulfurizing tower substantially.Along with the fast development of chemical industry technology, the rise of large-scale Coal Chemical Industry industry, production capacity is increasing, and the downstream process device is more and more higher to the desulfurization standard.How to reduce equipment investment, improve the disposal ability of desulfurizing tower, improve gas purification degree, become the difficult problem that all chemical enterprises are badly in need of solution, and the desulfurizing tower of these two kinds of structures can not satisfy the existing processes advantage.Its principal contradiction is that obstruction of desulfurizing tower internals and desulfurization purifying degree problem on the low side are more serious, and disadvantage is also more and more outstanding, directly has influence on the ordinary production of enterprise.
Summary of the invention:
The utility model discloses a kind of quick turbulence type desulfurizing tower, utilizes high-efficiency turbulent flow formula gas-liquid mass transferring method, has remedied the defective of the stifled tower of material filling type and tubular type bubbler pressurization wet desulphurization technology.
Technical solution of the present utility model is as follows:
The top of tower body is the gas outlet; Be provided with spray plate in the tower body from top to down, liquid distribution trough and multilayer gas-liquid contact plate, the top of tower body is positioned at the inlet that is provided with of gas-liquid contact plate top, the bottom of tower body is a liquid collecting room, be evenly distributed with tap hole on the every gas-liquid contact plate, downspout is located between the two gas-liquid contact plates, the upper orifice of downspout is positioned at more than the plane of gas-liquid contact plate, lower nozzle is located on the lower floor gas-liquid contact plate plane, the superiors' inlet and liquid distribution trough UNICOM, doctor solution descends through the liquid distribution trough spray from inlet, air inlet pipe is located at the below that tower body is positioned at orlop gas-liquid contact plate, bottom and UNICOM of liquid collecting room that drain pipe is located at tower body discharge liquid, and the bottom of tower body also is provided with discharging tube.
In the utility model use, gas is directly contacted with the doctor solution bubbling that gets off from overhead streams through the gas-liquid contact plate from the tower body bottom, hydrogen sulfide in the gas rapidly and desulfurization alkali lye react, gas is with form upwards ascension under buoyancy of vesicle simultaneously, enter second layer gas-liquid contact plate rapidly, finish above-mentioned reaction equally, at last according to the degree of purification requirement, gas goes out tower again through multilayer gas-liquid contact plate behind demister.The gas purification degree of this moment can reach below the 5ppm.
The utility model is compared desulfurizing tower (the tower diameter: 2.2 meters, high 27 meters of same specification with tubular type bubbler wet method pressurization desulfur technology; Three layers of tubular type bubbler.Solution internal circulating load: 86m
3/ h.Pressure: 2.3MPa.), adopt the utility model desulfurizing tower, throughput is by 24000m
3/ h increases to 38000M m greatly
3/ h.Certain factory becomes desulfurizing tower because of often stopping up in filler in 1979, and resistance is higher, band night, export H
2S exceeds standard.
Good effect of the present utility model is: according to H
2S and aqueous slkali can carry out the feature of chemical reaction fast, adopt gas-liquid directly to contact, make dynamically contact between the gas-liquid, gas is dispersed into draft through the gas-liquid contact plate, bubbling contacts the turbulence mode mass transfer with uniqueness closely by liquid layer between gas-liquid, increased the contact area between gas-liquid greatly, gas was realized and the liquid fast chemical reaction in the extremely short time, improved the gas cleaning degree; The utility model has not only saved the filler and the tubular type bubbler of original tower, has also solved the desulfurizing tower internals and has stopped up the tower problem.Compare with the tubular type bubble tower with material filling type, its production capacity increases 50～60%, and pressure drop can reduce by 30%, and cost reduces by 50%.Apparatus structure is simple in addition, and is easy for installation, and operating flexibility is big, and the little mass-transfer efficiency height of tower resistance drop is convenient to the cleaning maintenance, and production cost is low, and practical application effect is remarkable.
