Abstract

PURPOSE:To surely remove and recover water insoluble fine oil droplet dispersed matter and water in water solution in a short time by passing water solution where water insoluble liquid is dispersed through a hydrophobic element and a hydrophilic element in this order. CONSTITUTION:Water solution where water insoluble fine oil droplets are emulsified and dispersed is first forcibly fed into a hydrophobic element housing tank A1 to come into contact with the hydrophobic element 1 and passed through the element 1 while the fine oil droplet dispersed matter is coagulated and gets fat on the fiber surface constituting the hydrophobic element 1 and parts around the fiber surface. Next, the water solution is forcibly fed to a hydrophilic element housing tank A2 to come into contact with a hydrophilic element 2 and passed through the element 2 while water and oil droplets are separated on the fiber surface constituting the hydrophilic element 2 and parts around the fiber surface. And, in the case the fine oil droplet dispersed matter has smaller specific gravity than water, it surfaces to be separated and is recovered from an outlet 5 and water is recovered from an outlet 6 and in the case the fine oil droplet dispersed matter has larger specific gravity than water, the recovery is reversed.

It requires a lot of labor to clean the inside, and in the method of using resin particles or fibers that absorb oil, the separation element is greatly consumed, which is costly and difficult to recover. It is a thing.

The outline of the operation of the apparatus for separating and recovering water and water-insoluble liquid of the present invention shown in FIG. 2 is clear from the figure. That is, an aqueous solution in which a fine oil droplet dispersion insoluble in water supplied from the inlet (4) is emulsified and dispersed,
First, it is pumped into the hydrophobic element storage tank (A 1 ) by the pump (P). Here, the aqueous solution passes through the hydrophobic element (1) while making contact with the hydrophobic element (1) according to the illustrated flow path. Then, the aqueous solution is pressure-fed to the hydrophilic element storage tank (A 2 ) and the hydrophilic element (2)
It passes through the element while making contact. When passing through the hydrophilic element, the fine oil droplet dispersion and water are almost in a separated state, and both are separated in the storage tank (A 2 ). Needless to say, when the specific gravity of the fine oil droplet dispersion is smaller than that of water, it is floated, separated, and collected from the outlet (5). On the other hand, water having a high specific gravity is collected from the outlet (6). It goes without saying that when the specific gravity of the fine oil droplet dispersion is larger than that of water, the discharge relationship of each liquid is reversed, contrary to the above.
