Abstract

Abstract An integral water purification system including a tank for containing unclean water located at the source with continual replenishment of said water in the tank, a cover for the tank to accumulate natural heat by the elimination of any disturbances by the elements and to aid such accumulation by the rays of the sun in order to vaporize the unclean water, a blower for moving the vapor to a pipe leading from an area of one temperature to an area of another and lower temperature such as from the crest to the depth of the sea, whereby the vapor is condensed into droplets and accumulated in a condensing unit as pure water and a pump to force the water from the final condenser to a fresh water storage tank for later use whereby potable water is obtained from unclean water with the use of natural forces and with a minimum of expenditure of artificial energy sources.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 201 words
An integral water purification system comprising apparatus located in a constantly existing source of impure water and including: a container having a lower portion provided with enclosing liquid retaining wall means for holding a substantially static body of impure water therewithin in corresponding static condition and closing off liquid flow of such water therefrom and further having valve means for continual replenishment of said water in said container from the constantly existing source of the impure water, a cover of flexible plastic material for said container for providing heat accumulation within said container whereby said water is directly vaporized and rises as a vapor to the upper portion of said container above such static body of impure water, means comprising cloth covered baffles in the container for increasing the evaporation area therewithin, a blower for moving said vapor across the upper portion of said container above such static body of impure water, a vapor pipe for receiving and transporting said vapor from an area of one natural temperature through an area of a lower natural temperature whereby said vapors are condensed into water, and means including a liquid pipe and a pump for transporting said condensed water to a storage tank.
Claim 2
Dependent Claim 201 words
An integral water purification system comprising apparatus located in a constantly existing source of impure water and including: a container having a lower portion provided with enclosing liquid retaining wall means for holding a substantially static body of impure water therewithin in corresponding static condition and closing off liquid flow of such water therefrom and further having valve means for continual replenishment of said water in said container from the constantly existing source of the impure water, a cover of flexible plastic material for said container for providing heat accumulation within said container whereby said water is directly vaporized and rises as a vapor to the upper portion of said container above such static body of impure water, means comprising cloth covered baffles in the container for increasing the evaporation area therewithin, a blower for moving said vapor across the upper portion of said container above such static body of impure water, a vapor pipe for receiving and transporting said vapor from an area of one natural temperature through an area of a lower natural temperature whereby said vapors are condensed into water, and means including a liquid pipe and a pump for transporting said condensed water to a storage tank.
Claim 3
Dependent Claim 66 words
The integral water purification system of claim 1 in which the pipe for receiving and transporting the vapors extends from adjacent the surface of the source of the impure water to a deeper and cooler depth and wherein a condensing container is disposed in the depths of the source of the impure water at the deeper end of said pipe for receiving and transporting said vapor.
Claim 4
Dependent Claim 31 words
The integral water purification system of claim 1 including an intermediate water aerating system and wherein the pipe for receiving and transporting said vapors passes indirectly through said water aerating system.
Claim 5
Dependent Claim 32 words
The integral water purification system of claim 1 in which the blower comprises means driven by natural wind forces for blowing air across the container above the static body of impure water.
