Figures 1-8 schematically illustrate 3 the water purification and conditioning device of the present invention. Fig. 1 shows the general schematic structure of the whole system of the present invention. Untreated water from the source enters the system via pipe 1. In Figure 2, the water flow then flows into a convective heat exchanger 2, where the water flow is preheated and the gas from the compressor is cooled. Water flows through pipe 1 into heat exchanger 2 . The heated refrigerant enters the heat exchanger via pipe 2a which spans the entire system within pipe 2b. All pipes are held by connection means 2c. The system achieves flow convectively and provides the fastest heat exchanger possible. The supplied water flow then enters main 15 and is distributed via line 16 to degassing tank 11 in FIG. 3 and controlled by valve 10 regulated by computer 38 .

The 4 degassing tanks each have a centrifugally working inner tank 11i with a volume of approximately 4 liters. The centrifugal movement is driven by a small high-speed motor 11h located on the tank bottom 11g. There is an inlet valve 10, an outlet valve 14 and a vacuum valve 12 outside the tank. Water flows into the centrifuge chamber, where it rotates at a speed of 3-4 thousand revolutions per minute. The centrifuge chamber is located in a vacuum chamber with a vacuum degree of 18-20 inches. The vacuum chamber is evacuated by a circulating vacuum pump 9 for 10 ~20 seconds later. The unit is then shut down and the vacuum valve closed, water is drained into manifold 40. The 4 degassing chambers are computer sequenced, one of which is always full, the other is empty, and the other two are either spinning or evacuated. The detailed operation for degassing is as follows. The preheated supplied water enters the degassing chamber through the pipe 16 and the valve 10, and enters the centrifugal chamber 11i through the opening 11k of the barrier 11j. Water is sprayed onto the inner wall of the chamber 11i by the rotary water spray head 11d. The centrifuge chamber 11i is driven by the motor 11h to rotate at a speed of 3-5000 revolutions per minute, while maintaining a vacuum state through the pipeline 17. The effect of water on the vacuum state is prevented by the barriers 11j and 11b. The vacuum port 11c is located above the barrier 11b. In sequence, a vacuum state is applied, the centrifugal speed is maximized, and water is sprayed onto the inner wall of the chamber 11i. The vacuum state is released and the degassed water flows out through the pipeline 13 and the valve 14 .

The deaerated water then enters the convective heat exchanger 25 where the water is heated to 126.67°C. In Fig. 4, the vegetable oil heated to 126.67°C enters the heat exchanger 25 through the pipe 25b. Deaerated water flows through conduit 40 . After gaining heat in the convection exchanger, the heated deaerated water flows out of conduit 26 . The oil flowing out through the pipe 25a is reheated. The isolating device 43 closes the pipeline for heating oil. The water flow then flows into channel 26 where water is sprayed through valve 27 into a heated (176.67°C) vacuum expansion chamber. FIG. 5 shows a heated vacuum expansion chamber 20 . Degassed water with a temperature of 121.11°C and a pressure of 10 PSI passes through the valve 27 and the pipe 28 (through the barrier 20c), and is sprayed onto the inner wall of the chamber through the injection port 20b. The temperature of the inner surface of the chamber was 176.67°C. Before spraying, a vacuum is pushed into the duct 23, which is blocked by the barrier 20d. This vacuum is confined within the tube by valves 24 , 21 and 27 . Valve 27 is opened to spray water, then valve 27 is closed and valve 21 is opened to allow steam to escape through opening 22 . The chamber is then recirculated. The water is immediately evaporated, leaving various residues behind after the vapor is vented via valve 21 and line 22 into convective brine cooler 30 . Figure 6 shows a brine convective heat exchanger for cooling and distillate. Vapor enters the convective heat exchanger via line 22 and cooled brine (-6.67°C) enters in the opposite direction via line 30b. The condensed cool purified water is discharged via conduit 30a and the heat carrying brine is discharged via conduit 30c to return to the cooler. The cooled brine line is isolated by cover 8. Microbe-free water is then discharged into the water storage tank 31 . Figure 7 shows a water storage tank 31 for purified water. Purified water enters the tank via pipe 31b. Water level sensors 39 and 39a control the operation of the system. The ultraviolet tube 31a maintains the sterile state of the purified water. Water is then pumped by pump 32 into the filter tank. A water level sensor 39 sends data to a computer used to control the different work zones of the system. The water tank is equipped with ultraviolet germicidal lamps to ensure the continuous sterility of the water. The water is then delivered via pump 32 to the point of use. Fig. 8 shows the filter box of the present invention, which is composed of a mineral replenishment column with a piping device, an activated carbon filter column, an automatic valve device and an automatic backsplash device. The purified water from the water storage tank enters the mineral replacement device 33 through the pipeline 33a. The mineral replacement device includes a porous stone containing a carefully calculated mineral composition, such as pumice with suitable mineral colloids. The mineral colloid mixture is placed in supply tank 33b and is designed to be circulated in required quantities through column 33, pipes 33g and 33d. After the cycle is complete, any excess is injected to 33f. This solution can flow through pipe 33g to perform backsplash work on the whole system as needed. Water from pipe 33a passes through the automatic backsplash system, pipe 35 enters automatic backsplasher 34a, then, through pipe 34d to the bottom of the carbon filter column and then flows out pipe 37 to the point of use.

The preheater (heat exchanger) 25 is heated by the vegetable oil (126.67°C) from the heat source and the pump 29. The vegetable oil pumped into the pipeline 41 and passed through its channel main pipe 42 can keep the thermowell of the vacuum expansion chamber 20 at 176.67°C. ℃ temperature. Pipes 43, 41 and 42 are all dual-purpose pipes (both inlet and outlet pipes).

Since there are 4 parallel batch steps in the design of the unit, the water flow is not much different from the flow through the system.

The automatic backsplash process is computer controlled and can be performed without the need for a water level command from the water tank 31 .

Because many variations and different embodiments are possible within the spirit and scope of the principles of the invention taught herein, and because many modifications may be made to the embodiments described in detail herein in accordance with legal requirements, it should be understood that The detailed description given here is illustrative rather than limiting.
