Description

Technical Field

[0001] The present application relates to the field of central direct drinking water supply, and in particular to a pH-adjustable hydrogen-rich mineralized central direct drinking water preparation and supply system. Background Art

[0002] As people's quality of life continues to improve, the demand for drinking water is also increasing. At present, more than 90% of people drink pH-neutral tap water, bottled drinking water or other drinking water on a daily basis. The community drinking water machines and pipeline central drinking water machines that have emerged in the past decade or so are all single production and supply of neutral water or weakly alkaline water.

[0003] Nutritionists believe that drinking weak alkaline water with a pH value of 7.5-8.5 can adjust the body's acid-base balance, neutralize excessive gastric acid, neutralize local acidity of esophageal reflux, and help improve human immunity. However, since gastric acid is a necessary condition for the stomach to digest food, weak alkaline water entering the stomach will increase the pH value of gastric juice, thereby reducing the ability of gastric juice to digest food. Therefore, although weak alkalinity is good, it is not suitable for drinking when the stomach is digesting food.

[0004] Medicine and nutrition also believe that hydrogen-rich water can eliminate free radicals, anti-oxidation, relieve the development of inflammation, increase intestinal motility, improve physical fitness, enhance immunity, and delay aging.

[0005] Weakly alkaline hydrogen-rich water combines the advantages of both weakly alkaline water and hydrogen-rich water, and has a health-care effect on people.

[0035] Figure 1The flowchart of a system for preparing and supplying hydrogen-rich central drinking water with adjustable pH according to an embodiment of the present application is shown. Figure 1 As shown, the central direct drinking water system includes: a water purification unit 100, an electrolytic chemical treatment unit 2000, a mineralization filtration unit 300, a selective constant pressure water supply unit 400 and a terminal 500, and also includes a PLC control unit electrically connected to each module. Among them, the water purification unit 100 is used to purify drinking water to obtain pure water; the electrolytic chemical treatment unit 200 is used to electrolyze the water treated by the water purification unit to obtain neutral hydrogen-rich water and / or weakly alkaline hydrogen-rich water; the mineralization filtration unit 300 is used to mineralize and filter drinking water so that the drinking water contains preset mineral trace elements; the constant pressure water supply unit 400 is used to adjust the drinking water supply pressure; so that the water pressure finally supplied to the user terminal 500 is within a suitable range. Moreover, the system can selectively supply one of neutral central direct drinking water and weakly alkaline central direct drinking water at a predetermined time according to preset rules.

[0036] It should be noted that the purpose of this system is to:

[0037] (1) Able to prepare and supply hydrogen-rich mineralized central drinking water with neutral pH and weak alkaline pH. The pH value of weak alkaline water ranges from 7.5 to 8.5 and can be adjusted as needed.

[0038] (2) Selectively supply neutral (hydrogen-rich, mineralized) central drinking water or weakly alkaline (hydrogen-rich, mineralized) central drinking water. That is, according to the general life pattern of people, neutral water is supplied when the stomach is full and weakly alkaline water is supplied when the stomach is empty. The pH value of gastric juice will not be increased by drinking weakly alkaline water when the stomach is digesting food; weakly alkaline water is only consumed when there is no food in the stomach to neutralize the acidity in the body.

[0039] (3) The central direct drinking water combines the three effects of electrolyzed weak alkaline direct drinking water, electrolyzed hydrogen-rich direct drinking water and mineralized direct drinking water to play multiple health care roles.

[0040] (4) While meeting the above objectives, the sodium ion content of the central direct drinking water is + ≤20mg / L, total dissolved solid content TDS≤100mg / L, suitable for infants to drink.

[0041] The preparation and supply system of the hydrogen-rich central direct drinking water with adjustable pH is composed of a water purification unit, an electrolytic chemical treatment unit, a mineralization filtration unit, a selective constant pressure water supply unit and a terminal. It has a simple structure and is easy to implement. The water purification unit is responsible for treating the raw water that is close to or meets the tap water standard into pure water that can be directly drunk, and ensures that its Na+ ≤ 20mg / L and TDS ≤ 30mg / L; the electrolytic chemical treatment unit is responsible for treating the pure water into neutral hydrogen-rich central direct drinking water or weakly alkaline hydrogen-rich central direct drinking water; the mineralization filtration unit is responsible for mineralizing the neutral hydrogen-rich water or weakly alkaline hydrogen-rich water, giving the water mineral trace elements that are beneficial to the human body, and ensuring that the mineralized water TDS ≤ 1 00mg / L; the mineralized neutral hydrogen-rich mineralized central direct drinking water and weakly alkaline hydrogen-rich mineralized central direct drinking water are respectively transported to corresponding containers through pipelines; the selective constant pressure water supply unit is responsible for transporting the neutral hydrogen-rich mineralized central direct drinking water or the weakly alkaline hydrogen-rich mineralized central direct drinking water to the user terminal, and can supply neutral hydrogen-rich mineralized central direct drinking water when the person is full, and supply weakly alkaline hydrogen-rich mineralized central direct drinking water when the person is fasting according to the general meal time pattern of the person. The customer can choose to use it by himself at the terminal.

[0042] The adjustable pH value refers to the pH value being adjusted or selected between neutral and weakly alkaline. When the stomach is full, neutral hydrogen-rich mineralized drinking water is chosen to prevent the stomach from lowering the pH value when digesting food, which does not affect the stomach's digestion of food; when the stomach is empty, weakly alkaline hydrogen-rich mineralized drinking water is chosen to neutralize the acidity in the body, which is beneficial to human health.

[0043] Furthermore, the water purification unit 100 in this system is responsible for treating raw water that is close to or meets the tap water standard into pure water that can be directly drunk, and ensuring that its Na + ≤20mg / L, TDS≤30mg / L. Specifically, the water purification unit includes: a raw water tank 110, a micron-level multi-media filter 120, an activated carbon filter 130, a security filter 140, a reverse osmosis high-pressure water pump 150, and a reverse osmosis membrane group 160. The water inlet of the raw water tank 110 is connected to the water network and is used to store tap water as a water source to be treated. The water outlet of the raw water tank 110 is connected to the water inlet pipeline of the micron-level multi-media filter 120 in the water purification unit 100. The water outlet of the micron-sized multi-media filter 120 is connected to the water inlet pipeline of the activated carbon filter 130; the water outlet of the activated carbon filter 130 is connected to the water inlet pipeline of the security filter 140; the water outlet of the security filter 140 is connected to the water inlet pipeline of the high-pressure water pump 150; the water outlet of the high-pressure water pump 150 is connected to the water inlet pipeline of the reverse osmosis membrane group 160; the water outlet of the reverse osmosis membrane group 160 is connected to the water inlet pipeline of the electrolytic chemical treatment unit 200.

[0044] In the present system, the micron-level multi-media filter 120 has an accuracy of 1 μm, and can intercept 99% of particles larger than 1 μm. Due to the filter cake effect, the interception particle size of the micron-level multi-media filter 120 is less than 1 μm, thereby better protecting the reverse osmosis membrane group 160. The security filter 140 in the water purification unit 100 has an accuracy of 2 μm, and its function is to ensure that there are no particles with larger diameters in the water source that passes through the pre-filtration, so as to prevent large particles from entering the high-pressure pump 150 and damaging the pump. The reverse osmosis membrane group 160 can ensure that the water desalination rate is between 97% and 99%, can remove hardness and effectively filter out chlorine, chloroform, heavy metals, organic pollutants, Escherichia coli, silt, rust and other most harmful substances, so that the direct drinking water meets the corresponding hygiene standards. The micron-grade multi-media filter 120 and the activated carbon filter 130 are provided with a first external discharge pipeline; the reverse osmosis membrane group 160 is connected to a second external discharge pipeline; the first external discharge pipeline and the second external discharge pipeline are both connected to the outside of the device for discharging wastewater.

[0045] Furthermore, the electrolytic chemical treatment unit 200 is responsible for treating the pure water into neutral hydrogen-rich central direct drinking water or weakly alkaline hydrogen-rich central direct drinking water. Specifically, the electrolytic chemical treatment unit 200 in this system includes: an electrolytic hydrogen enrichment device 210 and an electrolytic weak alkalization device 220. The water inlet of the electrolytic hydrogen enrichment device 210 is connected to the water outlet pipeline of the reverse osmosis membrane group 160 to prepare neutral hydrogen-rich direct drinking water. The water inlet of the electrolytic weak alkalization device 220 is connected to the water outlet pipeline of the electrolytic hydrogen enrichment device 210 to prepare weakly alkaline hydrogen-rich direct drinking water; the electrolytic weak alkalization device 220 is connected to the water inlet pipeline of the medical stone mineralization filter 310 in the mineralization filtration unit 330. The electrolytic hydrogen enrichment device 210 can prepare hydrogen-rich water with a hydrogen content of >1.6 mg / L and a neutral pH. The electrolysis weak alkalization device 220 can be started or stopped according to the PLC preset program. When started, electrolysis produces weak alkaline water, and when turned off, the pH value of the water is not changed (ie, the pH is neutral).

[0046] like Figure 1As shown, in this system, the mineralization filtration unit 300 is responsible for mineralization filtration of neutral hydrogen-rich central direct drinking water and weakly alkaline hydrogen-rich central direct drinking water, increasing the content of minerals beneficial to the human body, and obtaining neutral hydrogen-rich mineralized direct drinking water or weakly alkaline hydrogen-rich mineralized direct drinking water. The mineralization filtration unit 300 includes: a medical stone mineralization filter 310, a neutral hydrogen-rich direct drinking water storage tank 320, and a weakly alkaline hydrogen-rich direct drinking water storage tank 330. The water inlet of the medical stone mineralization filter 310 is connected to the water outlet of the electrolytic weak alkalization device 220, and the water outlet of the medical stone mineralization filter 310 is respectively connected to the water inlet of the neutral hydrogen-rich direct drinking water storage tank 320 and the water inlet of the weak alkaline hydrogen-rich direct drinking water storage tank 330, and an electromagnetic valve is provided on the connecting pipeline to perform opening and closing actions, and the neutral hydrogen-rich mineralized central direct drinking water being prepared is connected to the neutral hydrogen-rich direct drinking water storage tank 320, and the weak alkaline hydrogen-rich mineralized central direct drinking water being prepared is connected to the weak alkaline hydrogen-rich direct drinking water storage tank 330.

[0047] The medical stone mineralization filter 310 is a filter made of natural medical stone as a filter material.

[0048] Specifically, the water outlet of the medical stone mineralization filter 310 is connected to two tanks, a neutral hydrogen-rich central direct drinking water storage tank and a weakly alkaline hydrogen-rich central direct drinking water storage tank, but the two are not connected at the same time, and only one water storage tank is connected at the same time. At the same time, the rear end of the electrolytic hydrogen enrichment device is connected to the electrolytic weak alkalization device. When drinking water is treated, the electrolyte hydrogen enrichment device is continuously working, and the electrolytic weak alkalization device only works when preparing weak alkaline hydrogen-rich central direct drinking water. When supplying and preparing neutral hydrogen-rich direct drinking water, only the electrolytic hydrogen enrichment device works, and the electrolytic weak alkalization device does not work. At this time, after the electrolytic hydrogen enrichment device electrolyzes, the drinking water becomes hydrogen-rich drinking water and flows into the electrolytic weak alkalization device from the water outlet. However, the electrolytic weak alkalization device does not work at this time and does not process the neutral hydrogen-rich drinking water flowing in, thereby keeping the drinking water as neutral hydrogen-rich drinking water flowing out of the water outlet of the electrolytic weak alkalization device. At this time, the neutral hydrogen-rich central direct drinking water continues to flow into the medical stone mineralization filter 310 for mineralization treatment. At this time, the system controls the water outlet of the medical stone mineralization filter through PLC to be connected to the neutral hydrogen-rich central drinking water storage tank, but not to the weak alkaline hydrogen-rich central direct drinking water storage tank.

[0049] Furthermore, when it is necessary to prepare and supply weakly alkaline hydrogen-rich central direct drinking water, the electrolyte hydrogen enrichment device and the electrolysis weak alkalization device both work, and the treated water is weakly alkaline central direct drinking water, and flows into the mineralization filtration device through the water outlet of the electrolysis weak alkalization device for mineralization treatment. At this time, the system controls the water outlet of the mineralization filtration device through PLC to connect to the weakly alkaline hydrogen-rich central direct drinking water storage tank, and supplies and stores weakly alkaline central direct drinking water to the weakly alkaline central direct drinking water storage tank. At this time, the water outlet of the medical stone mineralization filter is not connected to the neutral hydrogen-rich central direct drinking water storage tank.

[0050] The selective constant pressure water supply unit 400 is responsible for delivering neutral hydrogen-rich mineralized central direct drinking water or weakly alkaline hydrogen-rich mineralized central direct drinking water to the water use end through a pipeline. It can automatically switch the supply in time periods according to the time set by the program, or it can be self-service selected at the user end. Specifically, the selective constant pressure water supply unit 400 includes: a selective constant pressure water supply pump group 410 and an ultraviolet sterilizer 420. The ultraviolet sterilizer 420 is arranged on the water supply pipeline, and the selective constant pressure water supply pump group 410 can deliver neutral hydrogen-rich mineralized central direct drinking water and weakly alkaline hydrogen-rich mineralized central direct drinking water to the user terminal 500 according to user needs. The terminal 500 screen is provided with function selection buttons including "neutral hydrogen-rich water" and "weakly alkaline hydrogen-rich water", which can be selected for drinking at different times according to the full and fasting life patterns.

[0051] It should be noted that, in the present system, the selective constant pressure water supply pump group in the selective constant pressure water supply unit is simultaneously connected to the weak alkaline hydrogen-rich central direct drinking water storage tank and the neutral hydrogen-rich central direct drinking water storage tank, but the selective constant pressure water supply pump group is not connected to the two tanks at the same time. When the system automatically supplies central direct drinking water, the system can control the selective constant pressure water supply pump group to connect to the weak alkaline hydrogen-rich central direct drinking water storage tank or the neutral hydrogen-rich central direct drinking water storage tank through the PLC control system according to the preset supply rules. Specifically, when weak alkaline central direct drinking water needs to be supplied according to the system's central direct drinking water supply rules, the system controls the selective constant pressure water supply pump group to connect to the weak alkaline hydrogen-rich central direct drinking water storage tank, and supplies weak alkaline hydrogen-rich water from the weak alkaline hydrogen-rich central direct drinking water storage tank to the terminal for user use. When neutral hydrogen-rich central direct drinking water needs to be supplied according to the system's preset drinking water supply rules, the system controls the selective constant pressure water supply pump group to connect to the neutral hydrogen-rich central direct drinking water storage tank, and supplies neutral hydrogen-rich water from the neutral hydrogen-rich central direct drinking water storage tank to the terminal for user use.

[0052] The central direct drinking water supply rules preset by the specific system can be the setting of a specific time period, such as supplying neutral hydrogen-rich central direct drinking water one hour before and after 12 noon, etc., or it can be determined based on some other setting conditions that the pH condition of the specific central direct drinking water supplied is weakly alkaline or neutral.

[0053] In one possible implementation, the electrolytic chemical treatment unit 200 can automatically control the operation and stop of the preparation system according to the water levels of the neutral hydrogen-rich water direct drinking water storage tank 320 and the weak alkaline hydrogen-rich water direct drinking water storage tank 330; the selective constant pressure water supply unit can automatically select neutral hydrogen-rich mineralized direct drinking water or weak alkaline hydrogen-rich mineralized direct drinking water to supply to the terminal at the water user end according to a pre-set time period.

[0054] In addition, in this system, each processing unit is controlled by PLC program control technology, and the water end is controlled to switch the supply of neutral hydrogen-rich water and weak alkaline hydrogen-rich water.

[0055] The present invention also provides a method for supplying hydrogen-rich central direct drinking water. Specifically, in this method, the opening time ratio of the neutral hydrogen-rich mineralized direct drinking water and the weakly alkaline hydrogen-rich mineralized direct drinking water in 24 hours a day can be adjusted arbitrarily, generally between 1:1.4-1:1; wherein, the opening time of the neutral hydrogen-rich mineralized direct drinking water is from 15 minutes before people eat to 2 hours after eating, and the weakly alkaline hydrogen-rich mineralized direct drinking water is open at other times. Usually, the period before and after meal time refers to 7:00-10:30 for breakfast time, 11:30-15:30 for lunch time, and 17:00-21:00 for dinner time every day, so neutral hydrogen-rich mineralized direct drinking water is supplied during the above time, and weakly alkaline hydrogen-rich mineralized direct drinking water is supplied during the rest of the day.

[0056] Furthermore, in one embodiment, the central direct drinking water supply adopts a 3-point setting method, and the breakfast time point T1, lunch time point T2 and dinner time point T3 need to be set respectively. After the time points are set, the system supplies neutral hydrogen-rich central direct drinking water at the following times:

[0057] [T1-15m:T1+120m]

[0058] [T2-15m:T2+120m]

[0059] [T3-15m:T3+120m]

[0060] Weakly alkaline hydrogen-rich central drinking water is supplied for the other 24 hours of the day. In this way, hydrogen-rich water of different pH values ​​can be adaptively supplied in different regions according to local dietary habits, thereby providing the best drinking water for the human body.

[0061] It should be noted that although this case is used as an example to introduce a preparation and supply system for central direct drinking water with adjustable pH, those skilled in the art will understand that this application should not be limited to this. In fact, users can flexibly set it according to personal preferences and / or actual application scenarios, as long as the design is reasonable.

[0062] In this way, by using a preparation and supply system for a PH-adjustable hydrogen-rich central drinking water, neutral hydrogen-rich mineralized drinking water and weakly alkaline hydrogen-rich mineralized drinking water can be supplied, and the device structure is simple and easy to implement. The water that people usually drink is mostly neutral water. Hydrogen-rich water has certain benefits for the human body. The water end can obtain two or more different water sources, which is more selective and more beneficial to the body; at the same time, the water supply time of neutral hydrogen-rich mineralized drinking water and weakly alkaline hydrogen-rich mineralized drinking water is distinguished, and neutral hydrogen-rich mineralized drinking water or weakly alkaline hydrogen-rich mineralized drinking water is supplied at different time periods. Weakly alkaline hydrogen-rich mineralized drinking water can be supplied during non-meal time, which has certain benefits for the human body; drinking weakly alkaline hydrogen-rich mineralized drinking water before and after meals will weaken the stomach's ability to digest food, so neutral hydrogen-rich mineralized drinking water should be supplied during meal times to ensure the demand for healthy drinking water.

[0063] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
