Percolator distillation system

Claim 2

The invention as described in claim 2 wherein said percolator means is composed of a stand pipe, arranged vertically in the center of said percolator still means, having an open end thereof below said inverted dish and within said confined volume, and a second open end at the top thereof, which top extends into the upper portion of said percolator still means.

Claim 3

The invention as described in claim 3 wherein said accumulator means is composed of a cylinder affixed to the upper portion of said vertical stand pipe, being open only at the top thereof.

Claim 4

The invention as described in claim 4 wherein said deflecting means is a deflecting surface suspended from the top of said percolator still means and situated directly above the upper opening of said stand pipe, thereby to catch and deflect liquids emitted from said stand pipe downwardly into said accumulator means.

Claim 5

Percolator distillation means for purifying a foaming liquid, comprising: a. a percolator still having side walls and a floor; b. a pressure generator within said percolator still for bringing said liquid to an elevated temperature and pressure, said pressure generator enclosed by the walls and floor of said percolator still and by an inverted dish having a flat outer periphery containing a plurality of small holes, which inverted dish fits closely to the walls of said percolator still and forms the upper surface of said pressure generator; c. heating means, for providing heat energy to the liquid contained within said pressure generator so as to raise the temperature and pressure of such liquid; d. a vertical transmission pipe having a lower opening within said pressure generator and an upper opening outside of and above said pressure generator, through which said liquid at said elevated temperature and pressure is free to rise and to be emitted from the upper opening thereof; e. a metal deflector positioned above said upper opening; and f. an accumulator closed on the bottom and positioned below said deflector and above said pressure generator, wherein the liquid which rises through said vertical pipe is ejected into an area of said percolator still having a relatively low pressure such that some of said ejected liquid vaporizes, and the remainder liquid is caused to strike said deflector causing an impact of such liquid against said deflector, the combination of said impact and said reduced pressure acting to destroy any foam associated with said liquid, said deflector positioned to direct said remainder liquid downward into said accumulator, the overflow from which falls and collects in said still above said inverted dish, liquid returning to said pressure generator through said small holes under equilibrium pressure conditions within the still.

Claim 6

The invention as described in claim 6 wherein said percolator distillation means is an element of a system for purifying a foaming liquid which is processed through a liquid-contaminating unit wherein it is contaminated, which system includes: a. first storage means, to store said liquid prior to utilization in said liquid-contaminating unit; b. second storage means, to accumulate said liquid after utilization in said liquid-contaminating unit; c. recovery means, to transform said some of said fluid which vaporizes, from a gaseous state to a liquid state; d. third liquid storage means, to accumulate the liquid output of said recovery means, said storage means maintaining said liquid at a pressure greater than that of the liquid in said first storage means; e. coupling means, providing flow from said first storage means through saId liquid-contaminating unit and thence to said second storage means, from said second storage means to said percolator still, coupling the vapor output of said percolator still to said recovery means, coupling the liquid output of said recovery means to said third liquid storage means, and coupling liquid from said third storage means to said first storage means.
