分離方法に関するものである。 The method for separating the phase-separated liquid mixture in towers and tanks is carried out by valve operation, meters, electric sensors, etc. In the method of operating a valve, the operation is often complicated, which requires labor and there is a risk of erroneous operation. Methods using electrical sensors require no effort and are less likely to malfunction, but the equipment costs are enormous. As a result of extensive research into a simple method for separating mixed liquids that does not require special equipment or labor and that operates reliably, the present inventors have discovered that this objective can be achieved by using a float. That is, the method of the present invention uses a closed container having liquid extraction sections at the top and bottom, in which the nozzle of the liquid extraction section can be sealed, and in which phases having different specific gravities to be separated are separated. touch 2
In a sealed container in which a float having a specific gravity intermediate to that of the liquid is pre-existing, the lowest liquid extraction part is closed, and a phase-separable mixed liquid to be separated is supplied from an arbitrary supply part of the container,
Step of leaving the mixed liquid still until phase separation Pressurely injects the liquid from the lower part of the container from the lowest liquid extraction part,
A process of discharging the liquid from the upper layer of the container from the uppermost liquid extraction part until the nozzle of the liquid extraction part is sealed by the float.Next, the lowermost liquid extraction part is opened, and the liquid from the lower part of the container is discharged from the lowermost liquid extraction part. The present invention relates to a float-type mixed liquid separation method characterized by comprising a step of discharging the liquid until a nozzle of the liquid extraction section is sealed by the float.

Then, a phase-separable mixed liquid to be separated, for example, a stock solution consisting of water with a specific gravity of 1 and mineral oil with a specific gravity of 0.8, is pressurized into the separation tank c and left to stand until the water and oil undergo phase separation. It is preferable that the liquid extraction parts a and b be located at the top and bottom of the separation tank c, respectively, but the mixed liquid injection part e may be located at any part of the separation tank c. By increasing the pressure, it is also possible to press fit from the liquid extraction part b. As shown in FIG. 1, 1-1, a float d, which had been placed in a tank in advance, floats in the middle of the interface between A and B in the stock solution that has been phase-separated into oils A and B. This is possible if the specific gravity of the float is between the specific gravity of A and B. After closing A, open C and drain water B from b. The float d descends as the water B descends, and seals the nozzle portion at b as shown in FIG. After closing C, open A and press the stock solution again through e. By repeating this operation, the proportion of oil A in tank c increases. This operation may be repeated as necessary, and the upper layer A in the stock solution is
This may not be necessary if the proportion of

After being filled with , C is opened, B is discharged from b, and it becomes ready to receive the undiluted solution again as shown in 1-3.

る。 In Fig. 2, it is important to finish the nozzle part that the float d makes contact with sufficiently smooth to ensure a complete seal. Further, the radius of curvature R ₂ of the nozzle portion and the radius of curvature R ₁ of the float d may be equal, but depending on the presence or absence of scale in the liquid or the quality of the liquid, it may be preferable that R ₁ <R ₂ . The shape of the float d is preferably close to a perfect sphere, and may or may not be hollow. If it is hollow, the specific gravity is adjusted by the thickness of the material or the substance to be sealed. If it is not hollow, it can be adjusted depending on the materials to be combined and their proportions, and is suitable when a delicate specific gravity is required or when there is a risk of breakage. The material of the float d can be appropriately selected depending on the type of liquid mixture to be separated, such as plastic, wood, or metal. A material made of stainless steel or the like is preferable because it can be used widely. Even when a mixed liquid is separated into not only two layers but also three or more layers, at least the top layer and bottom layer can be easily separated by using multiple floats that match the specific gravity of each layer to be separated. can. Regarding the intermediate layer, it is also possible to separate and discharge the intermediate layer by, for example, devising the uppermost liquid outlet so that the floats can be taken out in sequence.

ことも可能である。 The shape of the tank can be of any shape, such as horizontal, rigid, or spherical.
It is desirable to devise a structure near the liquid extraction part of the separation tank as shown in FIGS. That is,
It is important to create a predetermined curved surface in the tank from this side of the liquid extraction part to ensure that the float is guided to the nozzle part. For this purpose, it may be advantageous to use a plurality of floats of the same specific gravity. On the other hand, it is also possible to further automate the separation by electrically detecting the position of the float using a phototube or the like and electrically operating the opening and closing of the valve.
