Description

Technical Field

[0001] One or more embodiments of this specification relate to water purification treatment technologies, and particularly to a water purification system with adjustable mineralization. Background Art

[0002] The abundance of living substances has prompted people to think about healthy drinking water. Water purifiers are increasingly accepted and recognized by people because they can provide healthy drinking water. However, the reverse osmosis membrane filtration technology used in water purifiers filters out all substances in water. Pure water without any beneficial elements is not healthy drinking water in a certain sense and does not conform to the newly proposed concept of healthy drinking water.

[0003] Currently, the prior art adds beneficial mineral elements to water by adding mineral concentrates or using mineralization filter elements. Mineral concentrates are generally chemically refined and concentrated, and are not suitable for long-term addition and drinking. Therefore, the water purification industry mostly uses mineralization filter elements for the addition of beneficial substances. However, the raw materials of safe mineralization filter elements come from ores, and the mineral precipitation amount of ores is limited and the concentration is difficult to control and adjust. In order to achieve the addition of mineral content that meets the requirements, the filter material addition amount of general mineralization filter elements is very large, which will increase the price cost, and the concentration still cannot be regulated according to demand. Therefore, there is currently a lack of a technology that can control the cost and regulate the mineral content to meet the requirements. Summary of the Utility Model

[0004] To solve the above problems, one or more embodiments of this specification describe a water purification system with adjustable mineralization.

[0005] According to a first aspect, there is provided a water purification system with adjustable mineralization.

The outlets of the mineralization filter element and the post-carbon filter element are both communicated with the system water outlet. The air inlet assembly is used to introduce air bubbles into the fluid pipeline so that the fluid passing through the air inlet assembly from the system water inlet becomes micro-bubble water, and both the first fluid control assembly and the second fluid control assembly are used to perform flow blocking control on the fluid in the fluid pipeline.

[0006] Preferably, the system further includes a pressure reducing valve and a booster pump, and the connection between the air inlet assembly and the fluid pipeline is located between the pressure reducing valve and the booster pump.

[0008] Preferably, a third fluid control assembly is further provided at the outlet of the pretreatment filter element.

[0009] Preferably, the pressure reducing valve and the booster pump are sequentially arranged between the pretreatment filter element and the membrane filter element.

[0023] See Figure 1 , Figure 1It is a schematic structural diagram of a water purification system with adjustable mineralization provided by an embodiment of the present application. In the embodiment of the present application, the system includes an air inlet assembly 4, a mineralization filter element 14, and a post-carbon filter element 10 that are respectively arranged on a fluid pipeline. The air inlet assembly 4 is communicated with the inlet of the mineralization filter element 14 through a first fluid control assembly 13, and the air inlet assembly 4 is also communicated with the inlet of the post-carbon filter element 10 through a second fluid control assembly 9. The outlets of the mineralization filter element 14 and the post-carbon filter element 10 are both communicated with a system water outlet 11. The air inlet assembly 4 is used to introduce bubbles into the fluid pipeline so that the fluid passing through the air inlet assembly 4 from a system water inlet 1 becomes microbubble water. Both the first fluid control assembly 13 and the second fluid control assembly 9 are used to perform flow blocking control on the fluid in the fluid pipeline.

[0024] In the embodiment of this specification, the air inlet assembly 4 can be composed of a booster pump, an air inlet pump, or other devices that can introduce bubbles into the liquid in the fluid pipeline. By setting the shape and size of the filter nozzle connected to the fluid pipeline, fine bubbles can be mixed into the fluid to form a large amount of microbubble water. The microbubble water contains millions of nanoscale and micron-scale bubbles. After the microbubble water passes through the mineralization filter element 14, the ultra-high mass transfer characteristics of the bubbles themselves, the huge energy generated by the rupture, and free radicals can accelerate the removal of the filter media minerals in the mineralization filter element 14, thereby increasing the concentration of the fluid after passing through the mineralization filter element 14. In this way, it is not necessary to increase the amount of filter media added in the mineralization filter element 14 to ensure the concentration. Using an ordinary mineralization filter element 14 can meet the concentration requirements, and the air inlet assembly 4 can still be reused after the mineralization filter element 14 is replaced. Under the premise of ensuring the concentration, cost control is achieved. Through the setting of the air inlet assembly 4, the fluid entering the fluid pipeline from the system water inlet 1 will first pass through the position of the air inlet assembly 4. After the fluid in the pipeline forms microbubble water, it will be introduced into the mineralization filter element 14 and / or the post-carbon filter element 10, ensuring that when the air inlet assembly 4 is working, the fluid entering the mineralization filter element 14 and / or the post-carbon filter element 10 is microbubble water.

[0025] Each fluid control component is arranged at different positions in the system to perform choke control on different fluid pipeline positions in the system. That is, when the fluid control component is opened, the fluid can pass through the fluid control component, and when the fluid control component is closed, the fluid will be cut off and blocked and cannot pass through the fluid control component. The fluid control component can specifically use a control valve, a control pump, etc. The control valve can use an electromagnetic valve, an electrically controlled valve, or a manual control valve such as a ball valve or a globe valve. The control pump can be selected from a water pump, a metering pump, a gear pump, etc. When a control pump is selected as the fluid control component, the control pump will be disconnected when it is not working, so as to achieve the closing effect of the valve. When a control pump is selected, the flow rate of the fluid in the pipeline can also be controlled. According to different actual designs, different fluid control components can specifically select different structures. For example, in the embodiment of the present application, the first fluid control component 13 selects a control pump, and the second fluid control component 9 selects a control valve. In other embodiments as shown in Figure 2 , both the first fluid control component 13 and the second fluid control component 9 select control pumps. When both use control pumps, the outlet concentration range of the mineralized concentration mixed water is larger, and stepless adjustment can basically be achieved. In addition, in other implementable ways, control valves, etc. can also be selected.

[0026] In addition to the mineralization filter element 14, a post-carbon filter element 10, that is, a post-activated carbon filter element, is also arranged in parallel in the pipeline. The post-carbon filter element 10 can further adsorb the remaining odor in the water. The post-carbon filter element 10 can specifically select a carbon rod filter element, a wet method filter element, etc. By controlling the first fluid control component 13, the second fluid control component 9, and the air intake component 4 in the system, the staff can realize different pipeline passage conditions, and then adjust the concentration of the pure water output from the system outlet 11 through different pipeline passage conditions. Specifically, at least the following five mineral concentration situations can be realized:

[0027] No concentration: The air intake component 4 does not work, the first fluid control component 13 does not work, the second fluid control component 9 works, and the filtered water will directly pass through the post-carbon filter element 10, so that the outlet water does not contain any added minerals.

[0028] Low concentration: The air intake component 4 does not work, the first fluid control component 13 works, the second fluid control component 9 works, and the filtered water is mixed with the post-carbon filter element 10 and the mineralization filter element 14, so that the outlet water contains a low concentration of minerals.

[0029] Medium concentration: The air intake component 4 does not work, the first fluid control component 13 works, the second fluid control component 9 does not work, and the filtered water passes through the mineralization filter element 14, so that the outlet water contains a medium concentration of minerals.

[0030] High concentration: The intake assembly 4 operates, the first fluid control assembly 13 operates, the second fluid control assembly 9 operates, the filtered water mixes with the post-carbon filter element 10 and the mineralization filter element 14, and there is the effect of micro-bubble water, so that the outlet water contains a high concentration of minerals.

[0031] Ultra-high concentration: The intake assembly 4 operates, the first fluid control assembly 13 operates, the second fluid control assembly 9 does not operate, the filtered water passes through the mineralization filter element 14, and there is the effect of micro-bubble water, so that the outlet water contains an ultra-high concentration of minerals.

[0032] In the above way, users can adjust the mineral concentration of the outlet water according to their own needs, and even if users need high-concentration outlet water, it can effectively ensure that the outlet water concentration meets the requirements.

[0033] In addition, the mineral concentration of the outlet water can be estimated. According to different situations and requirements, there can be many ways of estimation. As an example, assuming that the water flow rate of the control pump is L1, the water flow rate of the fluid entering from the system inlet 1 is L, and the precipitation concentration of the micro-bubble water after passing only through the mineralization filter element is determined by pre-testing as M, then the mineral concentration of the outlet water can be determined according to P = M * L1 / L. In other implementable ways, a concentration detection probe can also be directly set to detect the outlet water concentration.

[0034] In an implementable way, the system further includes a pressure reducing valve 5 and a booster pump 6, and the connection of the intake assembly 4 to the fluid pipeline is located between the pressure reducing valve 5 and the booster pump 6.

[0035] In the embodiments of this specification, in order to make the generation effect of micro-bubble water better, a pressure reducing valve 5 and a booster pump 6 are also provided in the fluid pipeline, and the intake assembly 4 is arranged between the pressure reducing valve 5 and the booster pump 6. Before the fluid reaches the position where the intake assembly 4 is located, it will pass through the pressure reduction of the pressure reducing valve, and the flow rate will decrease, and then it can better mix with the bubbles generated by the intake assembly 4. After mixing, the micro-bubble water is then pressurized by the booster pump to restore to the normal flow rate. According to different requirements, in special cases, the fluid can also pass through the booster pump 6 first and then through the pressure reducing valve 5 to reduce the concentration of the micro-bubble water.

[0036] In an implementable way, the system further includes a pretreatment filter element 2 and a membrane filter element 7. The inlet of the pretreatment filter element 2 is communicated with the system inlet 1, the outlet of the pretreatment filter element 2 is communicated with the inlet of the membrane filter element 7, the first outlet of the membrane filter element 7 is communicated with the inlet of the mineralization filter element 14 through the first fluid control assembly 13, and the first outlet of the membrane filter element 7 is also communicated with the inlet of the post-carbon filter element 10 through the second fluid control assembly 9.

[0037] In the embodiments of this specification, the raw water at the system water inlet 1 flows out from the first outlet of the membrane filter element 7 after being filtered by the pretreatment filter element 2. As Figure 2 shown, in other embodiments, a flow meter may also be provided at the outlet of the membrane filter element 7. The flow meter is used to detect the water outlet flow rate of the membrane filtration, so as to judge whether the state of the membrane filter element 7 is normal and whether the filter element needs to be replaced. Among them, the pretreatment filter element is mainly used to remove large particulate impurities in water, such as sediment, rust, suspended matter, etc., and adsorb residual chlorine, odor, color, and some organic substances and chemical pollutants in water. The membrane filter element is mainly used to filter out smaller particulate matters, bacteria, viruses, certain chemical substances and even minerals. When equipped with a reverse osmosis membrane, it can also effectively remove dissolved solids in water, including various salts.

[0038] In addition, if one of the first fluid control component 13 and the second fluid control component 9 is a control pump, the setting should be adjusted so that the water outlet flow rate of the control pump is not higher than the water outlet flow rate of the membrane filter element 7, so that part of the fluid can enter the filter element where the control valve is located, so that the system can generate the mixed water of the post-carbon filter element 10 and the mineralization filter element 14.

[0039] In an implementable manner, a third fluid control component 3 is also provided at the outlet of the pretreatment filter element 2.

[0040] In the embodiments of this specification, a third fluid control component 3 is also provided between the pretreatment filter element 2 and the membrane filter element 7. After the raw water is filtered by the pretreatment filter element 2, the third fluid control component 13 needs to be opened to pass through the membrane filter element 7 and flow out from the first outlet of the membrane filter element 7.

[0041] In an implementable manner, the pressure reducing valve 5 and the booster pump 6 are sequentially arranged between the pretreatment filter element 2 and the membrane filter element 7.

[0042] In the embodiments of this specification, the raw water first passes through the preliminary filtration of the pretreatment filter element 2, enters the position of the air intake component 4 through the pressure reducing valve 5 to form microbubble water, and then is pressurized by the booster pump 6 to restore the normal pressure and is transported to the position of the membrane filter element 7. After further filtration by the membrane filter element 7, it will be transported to the mineralization filter element 14 and / or the post-carbon filter element 10 according to the opening condition of the fluid control component.

[0043] In an implementable manner, the system further includes a first check valve. The air intake component 4 is communicated with the outlet of the membrane filter element 7 through the first check valve, and the first check valve is used to prevent the pure water at the system water outlet 11 from flowing back.

[0044] In the embodiments of this specification, when producing mineral water according to the concentration, if there is a control pump, the water remaining after the extraction operation of the control pump will flow back to the front of the pump. To prevent the finally produced pure water from flowing back, a first check valve is provided at the outlet position of the membrane filter element 7, and the first check valve can be a high-pressure check valve. After normal water production, the pressure of the outlet water will not be higher than the starting pressure of the first check valve. Therefore, the pure water at the system outlet 11 will not flow back.

[0045] In an implementable manner, the second outlet of the membrane filter element 7 is communicated with the wastewater outlet through a fourth fluid control assembly 8.

[0046] In the embodiments of this specification, the membrane filter element 7 has two outlets. The fluid after membrane filtration will flow out through the first outlet, and then pure water will be generated through the post-carbon filter element 10 and / or the mineralization filter element 14. The part rich in various impurities left after filtration will flow out as wastewater from the second outlet and be discharged from the wastewater outlet under the control of the fourth fluid control assembly 8.

[0047] In an implementable manner, the air intake assembly 4 includes an air intake pump and a second check valve 12, and the air intake pump is communicated with the fluid pipeline through the second check valve 12.

[0048] In the embodiments of this specification, the air intake assembly 4 can specifically be composed of an air intake pump and a second check valve 12. The second check valve 12 can block the flow unidirectionally, preventing the fluid in the fluid pipeline from entering the air intake pump, but allowing the gas generated by the air intake pump to enter the fluid pipeline through the second check valve 12.

[0049] In an implementable manner, a detection probe 15 is further provided between the outlet of the mineralization filter element 14 and the system outlet 11, and the detection probe 15 is used to detect the dissolved solid content in the fluid pipeline.

[0050] In the embodiments of this specification, a detection probe 15 can also be directly provided on the fluid pipeline of the system to detect the mineral concentration of the fluid in the fluid pipeline through the detection probe 15. The detection probe 15 can be a total dissolved solids (TDS) probe, a conductivity probe, a pH probe, etc. According to different actual requirements, the detection probe 15 can be directly provided at a position close to the system outlet 11 to directly detect the concentration of pure water, or the detection probe 15 can be provided at a position close to the outlet of the mineralization filter element 14. In this way, the detected concentration is that of the fluid passing through the mineralization filter element 14, rather than the concentration after mixing with the fluid of the post-carbon filter element 10.

[0051] As an example, assume that both the first fluid control assembly 13 and the second fluid control assembly 9 are control pumps, one with a working flow rate of L1 and the other with a working flow rate of L2. Assume that the detection probe 15 is asFigure 2 As shown, it is set on the branch of the mineralization filter element 14, and the detected mineralization concentration is T1. Since the mineralization concentration of the effluent of the post-carbon filter element 10 can be ignored, the final mineralized water concentration T after mixing is: T = (L1 * T1) / (L1 + L2).

[0052] In an implementable embodiment, a detection switch 16 is further provided at the entrance of the system water outlet 11.

[0053] In the embodiments of this specification, a detection switch 16 can be provided near the system water outlet 11. The detection switch 16 can be specifically set as different switches according to different requirements, such as a high-pressure switch, a low-pressure switch, a Hall switch, etc. The high-pressure switch is used to prevent equipment damage or safety accidents caused by excessive pressure. The low-pressure switch is used to ensure sufficient water supply and prevent the control pumps from idling and being damaged in a waterless state. The Hall switch is used to measure the water flow rate passing through, so as to track the usage of the filter element and predict the replacement time.

[0054] In the above embodiments, the descriptions of each embodiment have their own emphases. For parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0055] The above are only exemplary embodiments of the present disclosure, and the scope of the present disclosure cannot be limited thereby.

Those skilled in the art will readily think of other implementation manners of the present disclosure after considering the specification and practicing the disclosure herein.
