Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to a drinking water treatment system. Background Art

[0002] With the gradual improvement of people's living standards and the emphasis on health awareness, people are no longer limited to drinking water in their daily lives, and more functional water with trace elements is becoming more and more popular. The hydrogen element contained in water is divided into three nuclides: protium (1H), deuterium (2H or D), and tritium (3H or T). D2O formed by deuterium replacing protium in water molecules is heavy water, and water with a deuterium content lower than that of natural water is "deuterium depleted water" (DDW), or "light-poor water" or "ultra-light water". The deuterium content in natural water is about 150ppm, and the deuterium concentration in natural water varies with altitude and latitude, ranging from 135 to 155ppm.

[0003] The concept of hydrogen-rich water (referring to water rich in trace hydrogen molecules) originated in Japan. In 2013, its market size reached 20 billion yen. The concept of "hydrogen health" that emerged quickly gained favor among people who wanted to live a healthy and long life and stay away from diseases. Various hydrogen-rich waters, as the fruits of hydrogen molecule biomedical research, began to sell well in Japan.

[0004] Currently, the drinking fountains commonly used by people can purify water, but they cannot simultaneously prepare deuterium-depleted water and hydrogen-rich water that people can drink directly, or the preparation process is complicated and the cost is high. Summary of the invention

[0033] Figure 1 The structure diagram of a drinking water treatment system of an embodiment of the present application is shown. The drinking water treatment system provided by the present application includes a purification system 10, a separation system 20, a diversion system 30 and a hydrogen production system 40. Each system is connected in sequence. By treating tap water, the tap water is divided into pure water, low-deuterium water and hydrogen-rich water that can be directly drunk to meet the needs of different customers. Specifically, the purification system 10 can be connected to a household or commercial tap water pipe to purify the tap water, make it pure water and transport it out, and the user can directly drink the pure water.

[0034] The purification system 10 is connected to the separation system 20, and the separation system 20 includes a fractionation tower 21. Part of the pure water purified by the purification system 10 is transported to the fractionation tower 21, and is separated by the fractionation tower 21, and is transported out as low-deuterium water through the separation system 20. In addition, the separation system 20 is connected to the diversion system 30, and the separated low-deuterium water enters the diversion system 30, and the diversion system 30 includes a first conveying component 31 and a second conveying component 32. The low-deuterium water enters the first conveying component 31 and the second conveying component 32 for sterilization, and the low-deuterium water is directly transported out by the first conveying component 31, and the user can directly drink the low-deuterium water; the second conveying component 32 is connected to the hydrogen production system 40, and the hydrogen production system 40 is used to generate hydrogen and input the hydrogen into the second conveying component 32, and the low-deuterium water and hydrogen are mixed in the second conveying component 32 to form hydrogen-rich water, and are transported out through the second conveying component 32, and the user can directly drink the hydrogen-rich water. Through the drinking water treatment system provided by the present application, the various components in the drinking water treatment system are connected in series, and the tap water is treated in an internal circulation manner. Drinking tap water can be directly processed into pure water, low-deuterium water and hydrogen-rich water to meet the different needs of users. It has a simple structure, easy operation and efficient conversion.

[0035] Figure 2 The schematic diagram of the structure of the purification system of the drinking water treatment system of an embodiment of the present application is shown. The purification system 10 provided by the present application includes a purification component 11 and a purification pump 12. The purification component 11 includes a PP cotton component 111, an activated carbon component 112 and a reverse osmosis module 113. The tap water is directly connected to the input end of the purification component 11. The purification pump 12 is used to introduce the tap water into the purification component 11. The tap water is purified by the purification component 11 to make it pure water. Optionally, the purification component 11 is provided with a PP cotton component 111, an activated carbon component 112 and a reverse osmosis module 113 in sequence according to the conveying path of the tap water. In another embodiment of the present application, the activated carbon component 112 includes a granular activated carbon component and a compressed activated carbon component in sequence along the conveying path of the tap water. The compressed activated carbon component is made of powdered raw material activated carbon and a binder through kneading, extrusion molding, and then carbonization, activation and other processes. The particle size of the powdered carbon reaches the micron level, and the adsorption capacity is faster and stronger.

[0036] Optionally, the PP cotton component 111 includes 5μmPP cotton, which is filling cotton and is made of polypropylene fiber for artificial chemical fiber. Optionally, the reverse osmosis module 113 includes an RO membrane, and the RO (Reverse Osmosis) membrane refers to a reverse osmosis membrane. Generally, the flow of water is from low concentration to high concentration. Once the water is pressurized, it will flow from high concentration to low concentration, which is the so-called reverse osmosis principle. Using reverse osmosis technology, under a certain pressure, water molecules can pass through the RO membrane, while impurities such as inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses, etc. in the source water cannot pass through the RO membrane, thereby strictly separating the pure water that can be passed and the concentrated water that cannot be passed. The water purification system provided by the present application can prepare pure water with a conductivity of less than 5μS / cm. Finally, the prepared pure water is output through purification output pipe one 121 and purification output pipe two 122 respectively. Purification output pipe one 121 is connected to a terminal device, such as a faucet, so that users can directly use pure water. Purification output pipe two 122 is connected to the separation system 20 for further processing of the pure water.

[0037] Figure 3 The schematic diagram of the structure of the separation system of the drinking water treatment system of an embodiment of the present application is shown. The working principle of the separation system 20 is that the gas-liquid two phases are contacted by countercurrent, and interphase heat and mass transfer is carried out. The volatile component (hydrogen) in the liquid phase enters the gas phase, and the non-volatile component (deuterium) in the gas phase is transferred to the liquid phase, so that a light component with a higher concentration (low-deuterium water) can be obtained at the top, and a non-volatile component with a higher concentration (high-deuterium water) can be obtained at the bottom of the tower. The separation system 20 includes a fractionation tower 21, a heater 22 and a refrigerator 23. The separation liquid inlet pipe 211 is arranged in the middle of the fractionation tower 21. The separation liquid inlet pipe 211 is connected to the second purification output pipe 122 to transport part of the pure water filtered by the purification system 10 to the fractionation tower 21.

[0038] Combination Figure 1 As shown, a refrigerator 23 is arranged at the top of the fractionation tower 21, and a heater 22 is arranged at the bottom. When pure water enters from the middle of the fractionation tower 21, the tower section above the feed port of the fractionation tower 21 further concentrates the volatile components in the rising vapor, and the tower section below the feed port extracts the volatile components from the descending liquid. The vapor at the top of the tower is condensed, and a part of the condensate is returned to the fractionation tower 21 from the top of the tower as the internal reflux liquid, and the remaining liquid forms low-deuterium water and is output from one of the separation output pipes 212 at the top of the tower to the diversion system 30 for further processing; the liquid entering the bottom of the tower is heated and vaporized, and the vapor rises along the fractionation tower 21, and is circulated in sequence to form low-deuterium water for output, and the remaining liquid is output as the bottom waste water (high-deuterium water) through the second separation output pipe 213.

[0039] Optionally, the distillation tower is made of 304 stainless steel, the operating pressure is between 10KPa and 25KPa, and the temperature is between 46°C and 65°C.

[0040] Figure 4 The structural schematic diagram of the flow diversion system of the drinking water treatment system of an embodiment of the present application is shown, the flow diversion system 30 includes a first conveying component 31 and a second conveying component 32, one of the separation output pipes 212 is connected to the first conveying component 31, the first conveying component 31 includes a first delivery pump 311, a first water collecting tank 312 and a first sterilizer 313, the low-deuterium water separated by the separation system 20 flows into the first water collecting tank 312, the first delivery pump 311 is used to pump the low-deuterium water so that it circulates inside the first conveying component 31, and at the same time, the first sterilizer 313 is arranged on the circulation loop for disinfecting the low-deuterium water, and optionally, the first sterilizer 313 includes but is not limited to an ultraviolet sterilizer. On the one hand, the low-deuterium water after disinfection is delivered to the terminal device 33 through one of the first output pipes 314, and the user can directly use the low-deuterium water; on the other hand, the low-deuterium water is delivered to the second conveying component 32 through the second of the first output pipes 315.

[0041] The second delivery assembly 32 includes a second delivery pump 321, a second water collection tank 322 and a second sterilizer 323. The second first output pipe 315 is connected to the second water collection tank 322. The second delivery pump 321 is used to pump the deuterium-depleted water to circulate inside the second delivery assembly 32. At the same time, the second sterilizer 323 is arranged on the circulation loop to sterilize the deuterium-depleted water. Optionally, the second sterilizer 323 includes but is not limited to an ultraviolet sterilizer. Figure 1 As shown, the hydrogen production system 40 is connected to the second transport component 32, and the deuterium-depleted water is transported to the hydrogen production system 40 through one of the second output pipes 324, and the hydrogen prepared by the hydrogen production system 40 is input into the second water collecting tank 322, so that the deuterium-depleted water in the second water collecting tank 322 is mixed with the hydrogen to form hydrogen-rich deuterium-depleted water, and finally output to the terminal device 33 through the second second output pipe 325, so that the user can directly use the hydrogen-rich deuterium-depleted water.

[0042] Optionally, the first water collecting tank 312 and the second water collecting tank 322 have a capacity of 20 L and are made of 304 stainless steel.

[0043] In another embodiment of the present application, in order to facilitate monitoring of the gas pressure, liquid level, etc. in the second water collecting tank 322, a pressure controller and a liquid level controller are provided in the second water collecting tank 322.

[0044] In another implementation mode of the present application, in order to facilitate the adjustment of the temperature of various prepared waters, a temperature controller can be provided on the terminal device. The pure water separated by the purification system, the deuterium-depleted water separated by the separation system, and the hydrogen-rich deuterium-depleted water formed by the separation system and the hydrogen production system can all obtain different temperatures under the control of the temperature controller, thereby meeting the different needs of users.

[0045] Figure 5 The schematic diagram of the structure of the hydrogen production system of the drinking water treatment system of an embodiment of the present application is shown, and the hydrogen production system 40 includes an electrolytic cell group 41, a water tank 42, a water / gas separator 43, a purification pipe 44 and a pressure flow controller 45. Deuterium-depleted water is transported to the water tank 42 of the hydrogen production system 40 through one of the second output pipes 324 and decomposed by the electrolytic cell group 41. After the electrolytic cell group 41 is powered on, hydrogen is produced at the cathode and oxygen is produced at the anode. The hydrogen enters the water / gas separator 43, and the oxygen is directly discharged into the atmosphere; the water / gas separator 43 separates hydrogen and water, and the hydrogen enters the dryer for dehumidification, and is adjusted to the rated pressure by the pressure regulating valve 44, the pressure flow controller 45, etc., and then transported to the second delivery component 32 through the gas output pipe 46. Optionally, the rated pressure is between 0.02MPa-0.45MPa. The pressure of hydrogen generated by the electrolytic cell group is controlled by a sensor. Optionally, the set value of the pressure is about 0.45Mpa. When the pressure reaches the set value, the power supply of the electrolytic cell group is cut off; when the pressure drops below the set value, the power supply is restored.

[0046] Furthermore, the present application provides a control system for controlling the working pressure and temperature of the distillation tower in the separation system and the pressure and flow rate of the hydrogen output in the hydrogen production system, so as to obtain low-deuterium water with different deuterium contents and hydrogen-rich water with different hydrogen contents.

The control system is provided with a touch screen interface, through which the temperature of various waters and the content of deuterium and hydrogen can be adjusted, so as to prepare low-deuterium water with a deuterium content of less than 100ppm and hydrogen-rich low-deuterium water with a hydrogen content of more than 1400ppb.

[0047] The drinking water treatment system provided by the present application is suitable for large-scale industrial preparation of hydrogen-rich low-deuterium water and small-scale household hydrogen-rich low-deuterium water.
