Description
One, technical field
The invention belongs to chemical industry mass transfer and separation technology field.
Two, background technology
Extractor is used very extensive in industries such as chemical industry, medicine, metallurgy.Clarification extractor floor space is big, filler, sieve plate, disk extraction tower body of the tower height, and the little energy consumption of centrifugal extractor treating capacity is big.One-level extraction can not meet the demands, plural serial stage usually, and centrifugal extractor can reach 30 grades in the technology that has.For a long time, abstraction technique accelerate extraction rate, dwindle the extraction tower size, reduce number of unit, cut down the consumption of energy aspect, progress is very little always.
Three, summary of the invention
The problem to be solved in the present invention:
The core of abstraction technique is to mix and separate two processes.Existing extraction process reinforcement technique or lay particular stress on to mix and despise separation, or despise to mix and lay particular stress on separation, quite unbalanced.
The mentality of designing of tower extractor lays particular emphasis on mass transfer, strengthen mixed process, as agitator clarification extractor, sieving board extractor, pulsed extractor, rotary disk extractor (comprising ZL99106151.9), their separating property is all bad, stay the tower time to divide foreign minister, extractor is on a grand scale.
Centrifugal extractor then lays particular emphasis on the reinforcement separation process.But its treating capacity is too little, and equipment investment and energy consumption are excessive, and Technological Economy is not strong, can not handle the material that contains solid phase, is difficult to be fit to the demand of picture base metal, chemical wastewater treatment.
The present invention will propose balanced the reinforcement and mix and separate novel and portable, economic, the high extraction yield of two processes, high extraction efficiency, be suitable for the bigger extractor of material scope.

Technical scheme one and technical scheme two all can transfer chemical reactor to and use.
Beneficial effect
The beneficial effect of technical scheme one:
Technical scheme one is compared with the tower extractor of tradition, has produced following beneficial effect.
1, the raising of extraction yield, extraction efficiency
This beneficial effect derives from the remarkable improvement of extractor function aspect following four.
The function of a, pre-dispersed emulsification
In tower extractor, light, heavy two-phase enters upper and lower respectively, and pre-dispersed function is very faint.
In extractor of the present invention, light phase liquid is microbeam from disc type distributor or gas phase from aerator and penetrates, and is dissectd by the heavy phase eddy flow is cross-section at once, forms gently mutually small liquid pearl or microbubble respectively, and removes with eddy flow rotation level immediately.
The aperture of liquid distribution trough can reach the dozens of micron now.The aperture of micro porous aeration head can reach several microns now.Eddy flow is sheared the light phase liquid pearl, the microbubble that form can be successively near the aperture of light phase distributor, micro porous aeration head, the approximate effect that reaches emulsification.
B, interface are upgraded
In extractor of the present invention, because the horizontal flow interlayer shear, that light phase liquid pearl, microbubble are squeezed is flat, tear or stretch, and light phase, gas phase are entad done, and motion sees through heavy phase.These two kinds of convection action have built a hoop, axially careful careful mass transfer system.Eliminated the generation condition of back-mixing fully.So superior microcosmic mixing condition be tower extractor too late far away.And this convection type is a kind of brand-new mechanism of mass transfer.
C, centrifugation function
The tower extractor of tradition relies on gravity to separate light phase and heavy phase, and the path and the Liu Ta time that need are all very long.Be separated in extractor of the present invention and mainly carry out on top, storehouse, the physical action that is relied on is a centrifugal action.Because pinwheel 5 dynamic balance performances are very good, can separate light just faster to be several times as much as the rotation of conventional agitator rotating speed, to produce the big centrifugal force that is several times as much as gravity.
D, dissolved air flotation function
Dissolved air flotation effect also force of gravity centrifugation is strong.
In a word, the differential way of contact in the extractor of the present invention, superior interface are upgraded and can be significantly improved extraction yield, have shortened the mass transfer time again.Separation process has significantly been accelerated in centrifugal, air supporting effect.Eddy flow has sequence to move on the ground, has eliminated the condition that produces back-mixing.So, to compare with the traditional tower extractor that separates with depending on the gravity mass transfer, extractor of the present invention relies on new extraction mechanism, disperseing to mix finishes well, extraction yield can be significantly increased, and the time that separation is finished shortens in the number/, and extraction efficiency is significantly increased.This just can bring the effect that extraction progression reduces in the extraction process.
2, the extractor size reduces significantly
In the extractor of the present invention, the path of shear history continuity and rotor speed hook between fluid layer, can be more much bigger than the light perpendicular operating path of tower extractor, add that extraction yield and extraction efficiency all have breakthrough raising, the height of extractor of the present invention and diameter are all little than the tower extractor of tradition, highly are reduced in 2～5 meters.And the height of traditional extraction tower 20～30 meters be very usual.So just can reduce the cost of extraction process significantly.
3, the liquid phase that can handle clip has solid phase
Extractor of the present invention can separate contained solid phase by centrifugal action, ensures carrying out continuously of extraction process.And traditional tower extractor runs into solid phase just fouling easily, obstruction.
4, energy consumption reduces
Compare with the clarification extractor, the not only little and much less of turbulent flow that extractor mixed process of the present invention produces, in-fighting is little, and mechanical energy is converted into the efficient height of liquid flowing energy.
Carry the pump lift demand to reduce after the tower height reduces, system energy consumption reduces.
The beneficial effect of technical scheme two:
The tradition centrifugal extractor adopts drum rotating, in power transmission shaft into and out of liquid phase.The processing and manufacturing difficulty is big, starts slowly, and treating capacity is little, the energy consumption height.
Centrifugal extractor concentrator bowl of the present invention 17 bottoms are tubaeform, for light the distribution mutually provides much bigger pre-dispersed area.The light phase mixed path in pre-dispersed back is with to separate the path harmonious.Separate contained solid phase by centrifugal action simultaneously.More the tradition centrifugal extractor has and special mix the storehouse and extra energy consumption is arranged, and can cause the rotary drum wearing and tearing when material contains solid phase.
The pin seedling of extractor hinged constraint of the present invention axially also is being easy to set, evenly is being connected in series in the evenly distributed layout of hoop energy, and after rotation was got up, the pin seedling leaned on the centrifugal force oneself to seek the equilbrium position.The pinwheel 5 of diameter 290mm has reached the rotating speed of 3000r/min very like a cork in actual tests.Pinwheel 5 starts load and stays and surplusly reduce 1/4th to 1/3rd.Vibration is more much smaller than traditional centrifugal extractor, and installation requirement significantly reduces, and noise is little.
The simplified processing technology of the high speed rotor pinwheel 5 of centrifugal extractor of the present invention, maintenance of equipment is judicial convenience also.The cost of integral device is reduced to below half of traditional centrifugal extractor.
