BACKGROUND OF THE INVENTION
1. Field of the Invention This present invention relates to a point of use water purification unit designed to continuously and completely purify water at all points of use such as homes, restaurants, hotels, military, sea and field units as well as desalination of sea water at the point of use. The device will remove all chemicals, all microorganisms and replete the water with essential ground minerals.
2. General Background of the Invention Pure water for consumption, use in cooking and to maintain hygiene is a universal need. The purity and safety of water is deteriorating world wide. Tap water is no longer safe in major U.S. and foreign cities. It is contaminated by microbes, chemicals, heavy metals and in many instances ground water and sewage which gets into the distribution systems which are old and dilapidated.
Improvement of municipal water treatment systems will be of little benefit. In line filtration and treatment along the distribution system will also be of little benefit because the distribution systems are old, leaky and in some instances are contaminated ~y lead joints. Pure water for our cities is a big challenge which will not be soon solved. It is therefore imperative that point of use water purification for all of the water used in the home be the immediate solution.
SUMMARY OF THE INVENTION
Accordingly, it is an object of this invention to provide a device that will accomplish the function of providing at the point of use a water treatment system that can convert any water into microbe free, chemical free, WO9~/49473 rCT~Ss7/11261 chlorine free, pleasant tasting, soft, mineral repleted water for the whole house, apartment, restaurant or other establishment.
Another object of the invention is to provide a system for water purification in which the feed water is preheated through a heat exchanger which takes energy from the systems refrigeration unit (condenser side) in order to conserve maximum energy.
Another object of this invention is to provide a thin water layer, centrifugal, vacuum chamber for degassing the feed water.
An additional object of this invention is to take advantage of the peculiar and little known physical character of degassed water. Pure water, when free of dissolved gases, may be heated above 100 degrees C (up to 180 degrees C.) without boiling, but upon further heating, boiling may occur with explosive violence. This steam at (100 degrees C.) occupies a volume 1700 times greater than water at lOo degrees C.
It is a further object of the invention to isolate the degassing chamber by a series of three (3) in line valves.
These valves are electronic and controlled by the on board computer controller.
Another object of the invention is to heat the degassed feed water to 260 degrees F. under pressure and then spray it into a heated 350 degrees F. vacuum chamber, where it flash vaporizes in an explosive manner, thereby providing the pressure and vaporization to evacuate the chamber into the condenser.
Another object of the invention is to provide a brine chilled counter current heat exchanger at 20 degrees F. to condense the vaporized pressured steam to chemically and microbiologically pure water at ambient temperature.
An additional object of this invention is to provide a holding tank containing a W light source to maintain a microbial free condition of the water and providing high water level and lower water level sensors to regulate w097/49473 PcT~ss7~ll26 system operation through the on board microprocessor.
It is a further object of the invention to provide a booster pump which through in line pressure sensors will provide the desired pressure and flow throughout the system. This pressure and flow will be augmented by smaller in line pumps, if necessary.
A further object of the invention is to pass the water of this invention, as it flows from the holding tank, through a colloidal mineral column (to replace trace minerals) and lastly through a carbon column to assure good taste and freshness of the water.
An additional object of the invention is to provide an electronically heated (or other energy source) vegetable oil circulated throuqh a jacket in the preheat heat exchanger and heated vacuum chamber.
A further object of the invention is to provide an electrical refrigeration unit to chill the brine of the counter current condensing chamber and to provide heat for the preheater.
An additional object of the invention is to provide a back wash capability for each part of the system which will contain a scale dissolving potable water for keeping the system clean. This back wash will be timed and sequenced by the computer processor.
Another object of the invention is to provide four degassing centrifugal vacuum chambers and four heated vacuum vaporization chambers, each of which operates as a batch process and is sequenced by the computer controller as sensors indicate the unit is operational from the stand point of temperature, pressure and vacuum.
Additional objects and advantages of the present invention will either be set forth in the description that follows, will be obvious from the description or may be learned by practice of the invention. The object and advantages of the invention may be obtained by the apparatus and method particularly pointed out in the appended claims.
W097/49473 PCT~S97/11261 In accordance with the principles of the present invention as embodied and as broadly described herein, a point of use water purification unit is revealed which continuously and completely purifies water at all points of use such as homes, restaurants, hotels and military field units, as well as desalinates sea water at the point of use.

DETAILED DESCR~PTION OF THE PREFERRED EMBODIMENT
References will not be made in detail to the presently preferred embodiment of the invention, examples of which are illustrated in the accompanying drawings. Throughout the drawings, like referenced characters are used to designate like elements.
The water purification and conditioning unit of the invention are schematically illustrated in Figures 1-8.
Figure 1 reveals a general schematic of the entire system of this invention. Raw water from the source comes into the system through conduit 1. In Figure 2, it then flows into counter current heat exchanger 2 where the water is preheated and the gas from the compressor is cooled. Water enters the heat exchanger 2 through conduit 1. The heated refrigerant enters the heat exchanger through conduit 2a -W 097/49473 PCTrUS97/11261 which traverses the system inside conduit 2b. All of the conduits are held by attachment means 2c. This system flows in a counter current fashion and allows the most rapid heat exchanger feasible. Feed water then enters manifold 15 and is distributed to degassing pots 11 of Figure 3 through conduit 16 and controlled by valve 10 which is regulated by computer 38. The four degassing pots have an inner centrifugally operated pot lli which is about four liters in size. The centrifugal motion is driven by a small high speed motor llh on the bottom of the pot llh.
There is an outer housing an inflow valve 10, an outflow valve 14 and a vacuum valve 12. Water flows into the centrifugal chamber where it is spun at 3-5 thousand RPM
contained in a vacuum of 18-20 inches by circular vacuum pump 9 for 10-20 seconds. The unit is then stopped and the vacuum valve closed, water drains in to manifold 40. The four degassing chambers are being sequenced by the computer such that one is always filling, one is emptying and the other two are spinning or pumping vacuum. The detailed operation of the degassing is as follows. Preheated feed water enters the degassing chamber through conduit 16, through valve 10 and enters the centrifugal chamber lli through opening llk of baffle llj. Water is sprayed onto the walls of chamber lli by rotary water jets lld. Chamber 111 is rotated at 3-5000 RPM by motor llh while a vacuum is maintained through conduit 17. The vacuum is protected from water by baffle llj and llb. Vacuum ports llc are above baffle llb. In sequence, vacuum is applied, centrifugal speed is maximum and water is injected onto the walls of lli. Vacuum is released and the degassed water exits through conduit 13 and valve 14.
Degassed water then enters counter current heat exchanger 25 where it is heated to 260 degrees F. In Figure 4, heated vegetable oil at 260 degrees F. enters heat exchanger 25 through conduit 25b. Degassed water enters through conduit 40. Heated degassed water exits conduit 26 after picking up the heat in the counter current ~ . . , exchanger. The oil exits through conduit 25a to be reheated. Insulation 43 covers the heated oil conduits.
The water then flows into conduit 26 where it is injected through valve 27 into the heated (360 degrees F.) vacuum expansion chamber. Figure 5 represents the heated vacuum expansion chamber 20. Degassed water at 250 degrees F. and 10 PSI pressure is injected through valve 27 and conduit 28 (which goes through baffle 20c) onto the wall of the chamber through ejection ports 2Ob. The inner surface of the chamber is 350 degrees F. Prior to the injection, a vacuum is pulled through conduit 23, which is shielded by baffle 20d. The vacuum is locked in by valves 24, 21 and 27. Valve 27 opens to inject the water. It then closes and 21 opens to allow exit for the steam through opening 22. The chamber then recycles. The water instantly vaporizes, leaving all residue behind as the steam ejects itself through vale 21 and conduit 22 into the counter current brine chiller 30. Figure 6 represents the brine counter current heat exchange for cooling the distillate.
Steam enters the counter current heat exchanger through conduit 22. The chilled brine (20 degrees F.) enters in the opposite direction through conduit 30b. The condensed, cool, pure water exits through conduit 30a and the heat laden brine exits through conduit 30c to return to the chiller. The chilled brine conduits are insulate by covering 8. Free, microbe free water then drains into holding tank 31. Figure 7 represents the holding tank 31 for the purified water. Pure water enters that tank through conduit 3lb. Level sensors 39 and 39a control the operation of the system. W tubes 31a maintain a microbe free tank of pure water. Water is then pumped by pump 32 into filter bank. Water level sensor 39 sends data to the computer which controls the various activation areas of the system. The tank contains W sterilizer lamps to assure continued microbe free water. The water is then taken to the point of use through pump 32. Figure 8 represents the filter bank of this invention which is made up of a mineral CA 0226ll94 l998-l2-29 W097/49473 PCT~S97/11261 repletion column and an activate charcoal filter with conduit means, automated valve means and automatic back wash means. The pure water from the holding tank enters the mineral replacement unit 33 through conduit 33a. The mineral replacement unit contains porous rock to which is bound a carefully calculated mineral composition held to the porous rock as pumice by a proprietary mineral colloid.
The mineral colloid mixture is held in feeder tank 33b and is programmed to cycle the desired amount through column 33, conduit 33g and conduit 33d. After cycling, any excess is injected into 33f. This solution then flows through conduit 33g on demand to back wash the entire system.
Water flows from conduit 33a through the automated back wash system, through conduit 35 into auto backwash 34a, then through conduit 34d to the bottom of the carbon filter bank and then out through conduits 37 to the point of consumption.
Preheater (heat exchanger) 25 is heated by vegetable oil from heat source and pump 29 (260 degrees F.). Heat jackets for vacuum expansion chamber 20 are kept at 350 degrees F. by circulating vegetable oil pumped into and returning through conduit 41 into manifold 42. The conduits 43, 41 and 42 are double conduits (both inflow and outflow).
Since there are four (4) parallel batch steps in this device design, the flow of water has no detectable difference from a flow through system.
Automatic backwash is computer controlled and is done at times of no use demands on the water level in tank 31.
