能な二液分離装置を提供することを目的とする。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method and apparatus for efficiently separating two liquids having different specific gravities in a mixed state, such as oil and water, fluorocarbon and water, and fluorocarbon and oil. To provide a two-liquid separation device, which is capable of separating oil and water from, for example, shipbuilding waste liquid and factory waste liquid, and further separating impurity liquids from drinking water, etc., and which is also capable of purifying the liquid to be separated after removing impurity liquids. With the goal.

ることを基本原理とするものである。[Prior Art] As techniques for separating two liquids in a mixed state, there are well-known techniques such as 0, baffle plate separation method, inclined plate separation method, coalescer single method, and the like. These methods involve installing obstacles or inclined plates in the flow path through which the mixed liquid passes, and in the process of passing through these obstacles or inclined plates, the two liquids are gradually separated over time due to the physical specific gravity difference. This is the basic principle.

結合電位も高く、従来の物理的手法のみによるものでは
二液分離は原理的に不可能であった。However, for example, in a suspended oil-water mixture, ions are adsorbed on the surface of the oil colloid particles, so a zeta potential is generated due to an electric double layer at the interface with the water liquid.
Due to the Coulomb force generated due to this zeta potential, the oil particles repel each other and are stably suspended. Especially in a low-concentration oil-water mixture, the distance between the oil colloid particles is large, so the zeta potential The Coulomb repulsion caused by the electric potential is much larger than the intermolecular attraction, so there was a problem in that the two liquids could not be separated using conventional physical methods. or,
In an oil-water mixture emulsified by mixing a surfactant, the oil particles are small and the bonding potential between water and oil particles is high, making it impossible in principle to separate the two liquids using only conventional physical methods. It was possible.

る問題があった。Furthermore, conventional two-liquid separators only have a two-liquid separation function, and if you try to reuse the liquid to be separated after removing impurities, a purification process using a separate purification device is required, which increases the processing work. There is a problem that it becomes complicated and the processing time becomes long.

The zeta potential of the liquid particles in the mixed liquid is neutralized during the process of passing through the mixed liquid circulation space, and as a result, the liquid particles aggregate and become coarse particles due to the action of intermolecular attraction. The coarse impurity liquid particles float or settle due to the difference in specific gravity with the surrounding liquid, and the mixed liquid is separated into a separation liquid mainly containing the impurity liquid and a liquid to be separated from which the impurity liquid has been removed.

The particles coagulate and become coarse particles due to the force between them, and float or settle depending on their specific gravity. If the impurity liquid after separation has a specific gravity that is lighter than the surrounding liquid, it will collect in a separated liquid collection container connected to the upper part of the main container, whereas if the specific gravity of the impurity liquid is higher than that of the surrounding liquid, it will collect in a separated liquid collection container connected to the bottom of the main container. The separated liquid collects in the separated liquid collection container. The impurity liquid collected in this way is periodically extracted from the separated liquid collection container, while the liquid to be separated from which impurities have been removed is discharged to the outside of the container through the space under which the liquid to be separated flows in the tubular electrode.

When charged electrodes with a potential difference applied to them are arranged concentrically with respect to the outer tube electrode, impurity liquid particles are aggregated and coarsened between each tube electrode and the charged electrode, and between the outer tube electrode and the charged electrode. The liquid to be separated after the impurity liquid has been removed is discharged to the outside of the container through a plurality of paths through the downstream space of the liquid to be separated in each tubular electrode.

て分離効率を高めることもできる。In addition, the voltage to be applied is set based on the magnitude that can cancel out the zeta potential of impurity liquid particles to be separated in the mixed liquid, but in general, the smaller the electric resistance of the mixed liquid, the higher the applied voltage. For example, in the case of an oil-water mixture, the AC voltage is IV/c+n-10V/cm, and for a mixture with high electrical resistance, such as a mixture of Freon and oil, it is 100/cm to 200V. An alternating current voltage of /cm is used. In addition, the applied voltage also depends on the state of the mixed liquid. For example, in the case of an oil-water mixed liquid that has been emulsified by mixing a surfactant, the bonding potential between oil particles and water particles is high, so the applied voltage is also 10V10I. ~500V/
It is necessary to set it to cII. In addition, for mixed liquids with low electrical resistance, it is necessary to use alternating current voltage because there is a risk of electrolytic corrosion of the electrodes when using DC voltage, but as mentioned above for mixed liquids with high electrical resistance. It is also possible to use a DC voltage or a superimposed voltage of an AC voltage and a DC voltage. In particular, when a superimposed voltage of a DC voltage and an AC voltage is used, the separation efficiency can be improved by devising a combination of both voltages.

The separated liquid is collected into the liquid tank 21, and the recovered liquid is returned to the inside of the main body container through the mixed liquid inflow lower, thereby repeating the two-liquid separation process and producing a separated liquid with higher purity. conduct.

油層の厚みを増大させて、油水界面位置を押し下げる。Since an alternating current voltage is applied between the outer cylinder electrode 1 and the charged electrode 3 and between the inner cylinder electrode 2 and the charged electrode 3, the dielectric 12 interposed between each electrode is polarized in the direction of the electric field, and the mixed liquid passes through. The space 5 is substantially the same as a large number of electrodes arranged adjacent to each other. The surface of the oil particles in the mixed liquid that passes through this multi-electrode space in an upward flow is charged in accordance with the charge in the space, causing the electric double layer to be destroyed and each oil particle to be repelled and suspended. The Coulomb repulsion caused by the zeta potential disappears. As a result, the oil particles aggregate and become coarse particles due to intermolecular attraction, and after aggregation, they float due to the difference in specific gravity with the water liquid. The floating oil collects in the upper layer in the separated oil storage space 9 formed at the top of the main body container to form an oil layer, and as time passes, the thickness of the oil layer increases and pushes down the oil-water interface position.

Although a considerable amount of the oil-water mixture can be separated by passing through this device once, in order to further reduce the oil concentration in the separated water, it is necessary to discharge the liquid from the liquid to be separated outlet 8 as shown in Fig. 2. It is preferable that the aqueous liquid is returned to the main body container A through the mixed liquid inflow lower, and the above-mentioned oil-water separation step is repeated multiple times.

We decided to neutralize the zeta potential of certain impurity liquid particles, aggregate the impurity particles into coarse particles due to intermolecular attraction, and collect and discharge the separated liquid that became coarse particles and floated or settled due to the difference in specific gravity. It is possible to efficiently separate mixtures of liquids with different specific gravities, such as chlorofluorocarbons and water, fluorocarbons and water, and fluorocarbons and oil. Moreover, the present invention can reduce the amount of zeta in impurity liquid particles.
Since the electric potential is neutralized and impurity particles are aggregated and coarsened by intermolecular attraction, it is possible to separate emulsified two-component mixtures that cannot be separated by conventional physical methods such as baffle plate methods. is also possible.
