Technical field
The present invention relates to the waste-oil scavenger and the method for a kind of liquid-liquid-solution solvent extraction water, relate in particular to a kind of from types of gas filled microbubbles oil eliminator and deoiling method.
Background technology
The nonferrous metallurgy product requires increasingly high to the control of oleaginousness, for example nickelous chloride product requirement solution oleaginousness is less than 1 mg/l, and aqueous phase has been carried organic phase secretly, and expensive extraction agent needs Separation and Recovery and utilization, reduces processing charges.Outer equipment of traditional oil removal by air bubbling directly blasts air, and bubble is big, and the oil removal by air bubbling effect is limited, and power consumption is many.Ultrasonic dehydration is also undesirable in the extracting system result of use, and its inverse process ultrasonic emulsification has been widely used in industries such as food medicine.The effect of fibrous nodules oil removing is better, but the organic phase of breakdown of emulsion and absorption can not in time separate with adsorbing fiber, saturated easily, need further to improve.Oil removing process that R and D are new and technology are extremely important, avoid causing disadvantageous effect to concerned process steps, worsen technological process, and the equipment lining of corrosion organic material reduces with the pollution of raffinate discharge to environment.
The method of physics breakdown of emulsion has stirring, concussion, rotation and filtration; Through violent stirring, concussion or rotation, the emulsive emulsion drop is fiercely collided and merge, perhaps use the physics emulsion splitter; By the oil droplet that water surrounds, make oil droplet assemble and merge through the filtration method interception.The efficient of bubble trap oil removing depends on the surface-area of bubble, and bubble is more little, and specific surface area is big more, and efficient is high more.These method demulsifications are relatively poor; The method of bubble trap, because the feeding bubble diameter is big, specific surface area is little, the capture effect is limited.
Summary of the invention
The objective of the invention is to be directed against the problem and shortage that exists on existing aqueous phase extracted oil removing process and the equipment, provide a kind of from the types of gas filled microbubbles oil eliminator.
Above-mentioned purpose realizes through following proposal:
A kind of from the types of gas filled microbubbles oil eliminator; It is characterized in that an end of said oil eliminator is provided with circular chamber and gas-floating chamber, on said gas-floating chamber, is provided with injector; The other end at said circular chamber and gas-floating chamber is provided with the clarifying chamber; In said clarifying chamber, be provided with polylith fiber filter catching sheet, be provided with the outlet of organic phase groove and outlet and water in the termination of said clarifying chamber, this oil eliminator also comprises recycle pump; The liquid feeding end of this recycle pump is located at said circular chamber bottom, and said outlet end is connected to said injector.
A kind ofly it is characterized in that from the types of gas filled microbubbles oil eliminator, said circular chamber and gas-floating chamber can with the split of said clarifying chamber, also can be disjunctor.
Use above-mentioned oil eliminator to carry out the method for oil removing; It is characterized in that; Said method comprising the steps of: aqueous phase extracted flows into the circular chamber from the types of gas filled microbubbles oil eliminator certainly from the clarifying chamber of extraction box; Utilize the high-speed rotating machine breakdown of emulsion of recycle pump, utilize the vacuum inhaled air to make the oil droplet come-up of aqueous phase, utilize the fiber of hydrophilic oleophobic to do and carry out the solid breakdown of emulsion and filter the oil droplet that interception is surrounded by water; Water after the oily water separation is crossed from flowing into solution storage tank or Lower tank, clarifies isolating oil reservoir and reclaims through organic phase groove and outlet derivation.
Beneficial effect of the present invention: the high-speed rotating machine breakdown of emulsion that utilizes centrifugal transferpump from types of gas filled microbubbles oil eliminator and deoiling method of the present invention; Utilize the fiber of hydrophilic oleophobic to carry out the solid breakdown of emulsion and filter the oil droplet that interception is surrounded by water; Utilize injector vacuum suction air and produce the very little dispersion gas of particle diameter; Reach the pneumatically supported purpose of capture, improved deoiling effect.
