Definitions
- 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.
- 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 100 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 UV light source to maintain a microbial free condition of the water and providing high water level and lower water level sensors to regulate system operation through the on board microprocessor.
- 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 through 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.
- 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.
- the device will remove all chemicals, kill all microorganisms and replete the water with essential ground minerals.
- the device is comprised of a computer monitored and controlled system for degassing, super heating and exploding water into a vacuum chamber, in which instant steam results.
- the steam is condensed in a counter current cold brine apparatus and stored in a holding tank containing ultraviolet light and is evacuated to the point of use by a booster pump flowing through a mineral repleting column and a carbon filter for freshness and the assurance of the absence of off taste.
- Containment means are provided for holding these various components together in a compact package.
- the entire unit is monitored and controlled by a series of sensors, drivers and a computer processor.
- the containment means and all components should be covered compact and packaged for ease of installation and simplicity of operation.
- the unit may be housed either indoors or outdoors.
- FIGURE 1 is a comprehensive schematic drawing of the entire unit with its various components as well as indications as to the working mechanism.
- FIGURE 2 is a detailed schematic of the intake water preheater unit which preheats the water from the cooling refrigeration unit condenser, showing the flow of hot gas and cool intake water in a counter current direction with the gas pipe being housed inside the water pipe.
- FIGURE 3 is a detailed schematic of the degassing centrifugal vacuum chamber; one of four such chambers working on a batch principle and sequenced by a computer.
- FIGURE 4 is a detailed schematic of the counter current heat exchanger which will bring the degassed water temperature to 260 degrees F. under pressure.
- FIGURE 5 is a detailed schematic of the heated vacuum expansion chamber of the invention with its heat source and regulator valve mechanism.
- FIGURE 6 is a detailed schematic of the brine counter current heat exchanger for cooling the steam distillate.
- FIGURE 7 is a detailed schematic of the ambient temperature holding tank, with level sensors and ultraviolet treatment tanks.
- FIGURE 8 is a detailed schematic of the filter tank: 1) mineral repletion column 2) carbon filter column.
- FIG. 1 reveals a general schematic of the entire system of this invention.
- Raw water from the source comes into the system through conduit 1.
- 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 l.
- the heated refrigerant enters the heat exchanger through conduit 2a -6- 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.
- the four degassing pots have an inner centrifugally operated pot Hi 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.
- 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 Hi through opening Ilk of baffle llj. Water is sprayed onto the walls of chamber Hi by rotary water jets lid. 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 lib. Vacuum ports lie are above baffle lib. In sequence, vacuum is applied, centrifugal speed is maximum and water is injected onto the walls of Hi. 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.
- 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 20b.
- the inner surface of the chamber is 350 degrees F.
- 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.
- FIG. 7 represents the holding tank 31 for the purified water. Pure water enters that tank through conduit 31b.
- Level sensors 39 and 39a control the operation of the system. UV 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 UV 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 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.
