摘要:
An electric field is applied to a coalescer type filter element (13) in which the mesh size decreases in a step-like manner toward its outside. A subject liquid is passed through the filter from its inside to outside. A primary processed liquid discharged from the filter is introduced into an oil-water separating space (24) provided outside the filter, which space has an elongated path and to which space an electric field is applied. While the primary processed liquid passes through the oil-water separating space, rise of separated oil and fall of separated water are facilitated.
摘要:
The present invention relates to an oil-water separation apparatus which permits oil-water separation of heavily polluted oil-water mixed liquids or mixed liquids of high viscosity oil and water, etc., to be efficiently made. The present invention consists in an oil-water separation apparatus characterized in that in a top-opened separator tank (A) into which oil-water mixed liquid is fed from a source liquid tank (B) in which the oil-water mixed liquid of the source liquid, being the object of treatment, is contained, the inside-tank space (5) is disected into an oil-water separation (A1) space and a separated crater containing space (A2), a partition plate (3) is hung in the tank, forming under its bottom a communication route (2) for enabling circulation between these two spaces, and while an oil outlet (7) is opened through the part of the tank wall where the separated oil accumulates, a plural number of charged plates (8a,b) on which a voltage is applied are arranged, each two of them vis-à-vis, in the aforementioned oil-water separation space (A1), said source liquid to be fed through the aforementioned oil-water separation space (A1)on which the electric field acts.
摘要:
A method of efficiently eliminating impurities, particularly of low molecular weight and low concentration, from electric insulating liquids by means of applying an electric field to the electric insulating liquid to charge the contaminant particles therefrom and then contacting the thus-treated liquid with at least one absorbent to remove the charged contaminant particles from said liquid by means of an absorbent having ion-radicals in its structure, such as zeolite, and then eliminating the rough particles therefrom by means such as a percolator, centrifuge or percipitation tank (7). In certain cases wherein a large amount of contaminants which interfere with the insulating properties of the electric insulating liquid are present, the electric insulating liquid is first heated and subsequently contacted with an absorbent prior to the step of applying an electric field to preliminary remove contaminants therefrom.

摘要:
An electrostatic adsorptive fluid filtering apparatus wherein an adsorbent provided in a flow path of fluid to be treated has adsorption capacity as well as adsorption power substantially improved as as a result of enhancement of a potential inherently carried by the adsorbent on its adsorptive hole surface by impressing a DC voltage onto a charging electrode provided with the adsorbent or by placing the adsorbent in an electric field.
