Abstract

Abstract A system for separating fluids from each other. The mixture of fluids to be separated is injected into a cylindrical tank so as to cause the fluids to rotate and thereby accelerate their separation into strata. A float valve at the top of the tank allows lighter fluids to be exhausted while a second float valve at the bottom of the tank provides for the exhaust of heavier fluids. In the event of an oil spill on an open body of water, the present invention would provide for the clean up of the oil slick by separating it from the water.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 180 words
A fluid separator comprising: a. a closed container; b. means for injecting a mixture of fluids having differing densities into said container so that said mixture is stratified; c. a top outlet valve at the top of said container to connect the interior of said container to a first exhaust pipe; d. a bottom outlet valve at the bottom of said container to connect the interior of said container to a second exhaust pipe; e. a plurality of ball floats, one for each of said outlet valves, ballasted to sink in the less dense fluid and to float in the more dense fluid; and f. a plurality of cages, one attached interiorly of said container to each of said outlet valves, each containing one of said ball floats, to keep said ball floats aligned with their respective valves such that the less dense fluid of said mixture is exhausted through said top outlet valve and the more dense fluid of said mixture is simultaneously exhausted through said bottom outlet valve depending upon the level of the interface between the fluids.
Claim 2
Dependent Claim 180 words
A fluid separator comprising: a. a closed container; b. means for injecting a mixture of fluids having differing densities into said container so that said mixture is stratified; c. a top outlet valve at the top of said container to connect the interior of said container to a first exhaust pipe; d. a bottom outlet valve at the bottom of said container to connect the interior of said container to a second exhaust pipe; e. a plurality of ball floats, one for each of said outlet valves, ballasted to sink in the less dense fluid and to float in the more dense fluid; and f. a plurality of cages, one attached interiorly of said container to each of said outlet valves, each containing one of said ball floats, to keep said ball floats aligned with their respective valves such that the less dense fluid of said mixture is exhausted through said top outlet valve and the more dense fluid of said mixture is simultaneously exhausted through said bottom outlet valve depending upon the level of the interface between the fluids.
Claim 3
Dependent Claim 29 words
A fluid separator as recited in claim 1 further comprising means for imparting rotation to said mixture to enhance stratification of the fluids of said mixture by centrifugal force.
Claim 4
Dependent Claim 49 words
A fluid separator as recited in claim 2 wherein said imparting means comprises means for directing the input flow of said mixture from said injecting means tangentially to the inner surface of the walls of said container at a point midway between the top and bottom of said container.
Claim 5
Dependent Claim 87 words
A fluid separator as recited in claim 3 further comprising: a. a plurality of portable buoyant platforms; b. means for skimming the surface of a fluid mixture, said skimming means connected to the input of said injecting means to provide a source for said mixture to said container, said injecting means being mounted on one of said portable buoyant platforms; c. a portable buoyant reservoir connected to said first exhaust pipe from said container, said container being mounted on a second one of said portable buoyant platforms.
