Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to a water treatment system. Background Technology

[0002] Reverse osmosis technology produces concentrate / wastewater. The pollutants in the wastewater are concentrated and discharged, which can prevent impurities from depositing and clogging the membrane surface, extend the membrane's service life, and ensure water purification efficiency and stable effluent quality.

[0003] Because of the high concentration of impurities and ions in the water, scale easily forms around the small orifices of the concentrate or wastewater solenoid valve, causing the water flow rate to decrease too quickly. This decrease in water flow rate then has a reciprocal effect on the membrane element, causing concentration polarization. Concentration polarization further reduces the membrane's permeability, creating a vicious cycle of "low flow rate → concentration polarization → scaling → even lower flow rate," which greatly reduces the lifespan of the membrane element.

[0004] In addition, concentrated water solenoid valves or wastewater solenoid valves are more prone to scaling and clogging than solenoid valves. Although valve manufacturers have made structural improvements, as long as scaling occurs, the possibility of clogging cannot be completely avoided. Utility Model Content

[0005] Therefore, it is necessary to provide a water treatment system that addresses the problem of scale buildup in the discharge pipes of current water treatment systems after long-term operation, which can clog the pipes.

[0006] The first aspect of this application provides a water treatment system, including a filter element, the filter element having a raw water inlet, a pure water inlet and a concentrated water inlet, the raw water inlet being connected to an inlet pipe, the pure water inlet being connected to a pure water pipe, and the concentrated water inlet being connected to a concentrated water pipe.

[0007] The water treatment system further includes a first control module and a second control module. The first control module and the second control module are adapted to be connected to the filter element to inhibit scale formation in the flowing water. The first control module and the second control module are connected in series so that water flows into the first control module first, and then flows into the second control module after the first control module is full.

[0008] In one embodiment, the first control module has a first set capacity, the second control module has a second set capacity, and the first set capacity is equal to the second set capacity.

[0009] In one embodiment, the first control module contains a first scale inhibitor, and the second control module contains a second scale inhibitor, wherein the specifications of the first scale inhibitor are smaller than those of the second scale inhibitor.

[0010] In one embodiment, the first control module has a first set capacity, the second control module has a second set capacity, and the first set capacity is greater than the second set capacity.

[0011] In one embodiment, the first control module contains a first scale inhibitor, and the second control module contains a second scale inhibitor, wherein the specifications of the first scale inhibitor are equal to the specifications of the second scale inhibitor.

[0012] In one embodiment, the first control module and the second control module are located on the concentrate pipeline, and the first control module and the second control module have preset pressures.

[0013] In one embodiment, a first control valve is also provided on the concentrate pipeline. The first control valve is located downstream of the second control module and is used to control the flow rate of the concentrate pipeline.

[0014] In one embodiment, the first control valve is a concentrate solenoid valve or a wastewater ratio solenoid valve.

[0015] In one embodiment, a second control valve is provided on the pure water pipeline, which is used to restrict the flow of pure water flowing out of the filter element along the pure water pipeline.

[0016] In one embodiment, the second control valve is a check valve.

[0017] In the aforementioned water treatment system, by connecting the first control module and the second control module to the filter element, when water flows through the first control module and the second control module, the first control module and the second control module can react with the scale ions in the water, thereby inhibiting scale formation on the discharge path. Thus, by setting the first control module and the second control module, scale formation and accumulation during long-term discharge are prevented from clogging the discharge pipe, ensuring the normal discharge of the discharge pipe.

[0022] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0023] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] Currently, during long-term use, various impurities and minerals in the water gradually deposit inside water treatment systems, forming scale. This continuous accumulation of scale not only narrows the discharge pipes of the water treatment system but can even cause complete blockage, thus affecting normal water discharge. Furthermore, scale problems can trigger a series of other issues, including increased equipment operating pressure, reduced overall system efficiency, and in severe cases, damage to the entire water treatment system, significantly increasing maintenance costs. In this application, the water treatment system is designed to prevent scale formation as water flows within it, thereby ensuring the long-term, stable, and smooth operation of the water treatment system.

[0026] like Figure 1 or Figure 2 As shown in the figure, this application provides a water treatment system including a filter element 10. The filter element 10 has a raw water inlet 11, a pure water inlet 12, and a concentrated water inlet 13. The raw water inlet 11 is used to connect to the inlet pipe 20, and the raw water is transported in the inlet pipe 20. The pure water inlet 12 is used to connect to the pure water pipe 30, and the pure water pipe 30 is used to transport the pure water output after being filtered by the filter element 10. The concentrated water inlet 13 is used to connect to the concentrated water pipe 40, and the concentrated water discharged by the filter element 10 after filtering the raw water is transported in the concentrated water pipe 40. The concentrated water is also called wastewater.

[0027] In addition, a first control module 70 and a second control module 80 are provided on the concentrate pipeline 40. Both the first control module 70 and the second control module 80 can react with scale ions in the flowing water to inhibit scale formation and blockage of the discharge pipeline during the discharge process, thereby ensuring that the concentrate can be discharged normally.

[0028] Specifically, the first control module 70 and the second control module 80 can be integrated together, or the first control module 70 and the second control module 80 can form two independent structures, and the outlet of the first control module 70 and the inlet of the second control module 80 can be connected by a connecting pipeline.

[0029] More specifically, the first control module 70 has a first set capacity, and the second control module 80 has a second set capacity, with the first set capacity equal to the second set capacity. Based on this, a first scale inhibitor 71 is incorporated into the first control module 70, and a second scale inhibitor 81 is incorporated into the second control module 80, with the specification of the first scale inhibitor 71 being smaller than that of the second scale inhibitor 81. For example, a first scale inhibitor 71 with a particle size of 1mm is added to the first control module 70, and a second scale inhibitor 81 with a particle size of 5mm is added to the second control module 80. The 1mm particle size of the first scale inhibitor 71 allows for more thorough contact with water, resulting in faster release of scale-inhibiting components and improved scale inhibition efficiency. Furthermore, the first scale inhibitor 71 has a more rapid effect on capturing and interfering with calcium and magnesium ions in the water, effectively preventing the formation of scale nuclei in a short time.

[0030] Furthermore, while the dissolution rate of the second scale inhibitor 81 is relatively slow, its sustained-release effect is better. Therefore, the second scale inhibitor 81 can continuously release scale-inhibiting components for a longer period, thus extending the duration of scale inhibition. Moreover, the second scale inhibitor 81 has relatively high stability in water and is not easily washed away or carried out by water flow. It should be noted that the filling ratio of the first scale inhibitor 71 in the first control module 70 and the second scale inhibitor 81 in the second control module 80 can be adjusted according to the hardness of the water.

[0031] In an optional embodiment, the first control module 70 has a first preset capacity, and the second control module 80 has a second preset capacity, wherein the first preset capacity is greater than the second preset capacity. The first control module 70 contains a first scale inhibitor 71, and the second control module 80 contains a second scale inhibitor 81, with the specifications of the first scale inhibitor 71 equal to those of the second scale inhibitor 81. Therefore, by increasing the volume of the first control module 70, water flows into the first control module 70 and remains there until it is completely filled before flowing into the second control module 80. This allows the water to remain in the first control module 70 for a longer period. During the process of filling the first control module 70, the first scale inhibitor 71 reacts with the injected water, and the longer time required to fill the first control module 70 ensures a more complete reaction. The second control module 80 has a smaller volume. When water flows from the first control module 70 into the second control module 80, the water can react with the second scale inhibitor 81 in the second control module 80 to further react and remove any structural ions that may be present in the water, thus ensuring that the water quality output from the second control module 80 is stable.

[0032] In an optional embodiment, the first control module 70 and the second control module 80 are typically installed in the concentrate pipeline 40. When installed in the concentrate pipeline 40, the first control module 70 and the second control module 80 are preset with a set pressure to adapt to the pressure in the concentrate pipeline 40. Of course, in principle, the first control module 70 and the second control module 80 can also be installed in the pure water pipeline 30 and the inlet water pipeline 20.

[0033] In an optional embodiment, the concentrate pipeline 40 is further provided with a first control valve 50, which is located downstream of the second control module 80, so that the flow rate of the concentrate pipeline 40 can be controlled by the first control valve 50.

[0034] Specifically, in this embodiment, the first control valve 50 can be either a concentrate solenoid valve or a wastewater ratio solenoid valve. The concentrate solenoid valve controls the flow of wastewater in the concentrate pipeline 40, switching it between flowable and non-flowable states, thus controlling the opening and closing of the concentrate pipeline 40. It is installed downstream of the second control module 80, connected to the concentrate port 13 of the filter element 10, and is responsible for opening the concentrate pipeline 40 during water production and closing it during shutdown. The wastewater ratio solenoid valve integrates a wastewater ratio adjustment function on the basis of the concentrate solenoid valve. Through a built-in flow limiting device (such as an adjustable bolt or a fixed orifice), it precisely controls the production ratio of wastewater and pure water, thereby directly affecting the working pressure and water purification efficiency of the filter element 10.

[0035] More specifically, the concentrate pipeline 40 includes a first pipeline 41, a second pipeline 42, and a third pipeline 43. The first pipeline 41 connects the concentrate outlet 13 and the inlet of the first control module 70, the outlet of the first control module 70 is connected to the inlet of the second control module 80, and the second pipeline 42 connects the outlet of the second control module 80 and the inlet of the first control valve 50.

[0036] Thus, the concentrated water output from the concentrated water outlet 13 of the filter element 10 flows unidirectionally along the first pipeline 41 to the inlet of the first control module 70. Then, the concentrated water enters the first control module 70 and reacts there, consuming some of the scale ions. After that, it is discharged from the outlet of the first control module 70 to the second control module 80. The second control module 80 then reacts with the scale ions in the input concentrated water and outputs the treated concentrated water to the second pipeline 42. The second pipeline 42 then supplies the treated concentrated water to the inlet of the first control valve 50. After passing through the first control valve 50, the treated concentrated water is input into the third pipeline 43. One end of the third pipeline 43 is connected to the outlet of the first control valve 50, and the other end of the third pipeline 43 outputs the concentrated water treated by the first control module 70 and the second control module 80.

[0037] In an optional embodiment, a second control valve 60 is provided on the pure water pipeline 30. The second control valve 60 can be a one-way valve. Thus, by setting the one-way valve, the pure water flowing out of the pure water outlet 12 can be controlled to flow only in one direction in the pure water pipeline 30.

[0038] Specifically, the pure water pipeline 30 includes a fourth pipeline 31 and a fifth pipeline 32. The fourth pipeline 31 connects the pure water port 12 to the inlet of the second control valve 60. One end of the fifth pipeline 32 is connected to the outlet of the second control valve 60, and the other end of the fifth pipeline 32 is used to output pure water.

[0039] Therefore, through the cooperation of the first control module 70 and the second control module 80, scaling in the water treatment system during water discharge can be effectively limited, ensuring the overall efficient and stable operation of the water treatment system.

[0040] Therefore, this water treatment system is designed to effectively prevent scale buildup and blockage, reduce maintenance costs and operational stress, and ensure unobstructed operation during long-term use, thereby guaranteeing the normal operation and stability of the water treatment system.

[0041] Furthermore, by installing a first control module 70 and a second control module 80 within the water treatment system, the scale inhibitors within these modules can react promptly with scale-forming ions in the concentrated water as water flows through them, preventing scale formation. This ensures the long-term stable operation of the water treatment system, reduces maintenance costs, and improves its overall efficiency. In this water treatment system, the first control module 70 and the second control module 80 can not only be installed in the concentrated water pipeline 40, but also, in principle, in the pure water pipeline 30 and / or the inlet water pipeline 20, to control scale formation in other discharge pipelines.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
