Description

Technical Field

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

[0002] The reverse osmosis system in pure water equipment has strict requirements for the influent water. When the influent water quality is not up to standard, it will cause pollution or damage to the reverse osmosis membrane, affecting the output water quality and normal operation of the pure water equipment.

[0003] The reverse osmosis membrane in related technologies can lead to a decrease in water production during use. Utility Model Content

[0004] In view of the above problems, this application provides a water supply system and a battery production line that can solve the problem of reduced water production caused by reverse osmosis membranes during use.

[0005] To solve the above-mentioned technical problems, in a first aspect, this application proposes a water supply system, including: a water tank, a first booster pump, a heating element, a first high-pressure pump, and a reverse osmosis element;

[0006] The input end of the first booster pump is connected to the water tank, the output end of the first booster pump is connected to the input end of the heating element, the output end of the heating element is connected to the input end of the first high-pressure pump, and the output end of the first high-pressure pump is connected to the reverse osmosis element.

[0007] In the technical solution of this application embodiment, water in the water tank passes through a first booster pump, a heating element, and a first high-pressure pump before entering the reverse osmosis unit for treatment to obtain deionized water. Since the reverse osmosis membrane in the reverse osmosis unit shrinks at low water temperatures, leading to a decrease in water production, this application incorporates a heating element to heat the water flowing into the reverse osmosis unit. This prevents the water flowing into the reverse osmosis membrane from being too cold, thus avoiding membrane shrinkage and increasing water production.

[0008] In some embodiments, the water supply system further includes a first bypass pipe, one end of which is connected to the first booster pump, and the other end of which is connected to the first high-pressure pump. This way, when the water temperature in the tank is high, there is no need to heat the water through a heating element.

[0009] In some embodiments, the water supply system further includes a first filter disposed between the heating element and the first high-pressure pump, or...

[0010] The first filter is installed between the first bypass pipe and the first high-pressure pump. In this way, impurities in the water can be filtered out.

[0011] In some embodiments, a first dosing port is provided between the heating element and the first filter; or...

[0012] A first dosing port is provided between the first bypass pipe and the first filter. This allows the reducing agent to reduce oxides in the water, thereby lowering the oxidizing properties and improving water quality. Simultaneously, oxides and other impurities in the water accumulate on the reverse osmosis membrane, forming fouling and membrane fouling. This leads to a shortened membrane lifespan and reduced desalination efficiency. The reducing agent helps clean the reverse osmosis membrane and reduce membrane fouling. The reducing agent can reduce oxides and organic matter on the membrane, converting them into easily cleanable inorganic salts and water, thus extending the membrane's lifespan and improving desalination efficiency.

[0013] In some embodiments, a second dosing port is provided between the heating element and the first filter, or...

[0014] A second dosing port is provided between the first bypass pipe and the first filter. This prevents calcium and magnesium ions in the water from combining to form scale.

[0015] In some embodiments, the water supply system further includes a second high-pressure pump, one end of which is connected to the first filter, and the other end of which is connected to the reverse osmosis unit. This allows the second high-pressure pump to be activated if the first high-pressure pump fails, ensuring the normal operation of the overall system.

[0016] In some embodiments, the water supply system further includes a second bypass pipe, one end of which is connected to the output end of the heating element and / or the first bypass pipe;

[0017] The other end of the second bypass pipe is connected to the first high-pressure pump and / or the second high-pressure pump. In this way, when the water quality is good, it can be directly delivered to the first high-pressure pump and / or the second high-pressure pump through the second bypass pipe without needing to be filtered through the first filter.

[0018] In some embodiments, the water supply system further includes a first control valve disposed on the first bypass pipe. This facilitates the control of opening or closing the first bypass pipe.

[0019] In some embodiments, the water supply system further includes a controller and a water temperature detection device;

[0020] The water temperature detection device is installed on the reverse osmosis unit and is used to detect the water temperature at the input end of the reverse osmosis unit.

[0021] The controller is electrically connected to both the water temperature sensor and the heating element. When the water temperature detected by the water temperature sensor is lower than a threshold, the controller activates the heating element. This allows for convenient control of the heating element's operation based on the water temperature detected by the water temperature sensor.

[0022] In some embodiments, the water supply system further includes a second booster pump, one end of which is connected to the water tank, and the other end of which is connected to the heating element and / or the first bypass pipe. This allows the second booster pump to be activated if the first booster pump fails, ensuring the normal operation of the overall system.

[0023] In some embodiments, the water supply system further includes a second control valve disposed at the input end of the heating element; and / or,

[0024] The water supply system further includes a check valve, which is located at the output end of the first booster pump; and / or,

[0027] In some embodiments, the water supply system further includes a second cleaning component connected to the reverse osmosis unit for cleaning the filter element in the reverse osmosis unit. This facilitates the cleaning of the filter element in the reverse osmosis unit.

[0028] In some embodiments, the water supply system further includes a second recovery tank connected to the reverse osmosis unit for recovering wastewater after cleaning the filter element. This facilitates the recovery of wastewater after cleaning the filter element.

[0049] Currently, the reverse osmosis system in pure water equipment has strict requirements for the influent water. When the influent water quality is not up to standard, it will cause pollution or damage to the reverse osmosis membrane, affecting the output water quality and normal operation of the pure water equipment.

[0050] In reverse osmosis systems, water treatment is primarily achieved through RO (Reverse Osmosis) membranes. The working principle of RO membranes is based on reverse osmosis technology. Normally, water flows from low concentration to high concentration, but when water is under pressure, it can flow in the reverse direction, from high concentration to low concentration. This reverse flow allows water molecules to pass through the RO membrane, while most impurities such as inorganic salts, heavy metal ions, organic matter, colloids, bacteria, and viruses are blocked, thus purifying the water.

[0051] In related technologies, when the water temperature is low, the RO membrane will shrink when the water flows to it. At this time, the water production of the RO membrane will decrease, which will affect the operating cost.

[0052] Based on the above considerations, in order to solve the problem that when the water temperature is low, the RO membrane will shrink when the water flows to it, thus reducing the water production of the RO membrane, a water supply system is designed. The water supply system includes: a water tank, a first booster pump, a heating element, a first high-pressure pump, and a reverse osmosis unit. The input end of the first booster pump is connected to the water tank, the output end of the first booster pump is connected to the input end of the heating element, the output end of the heating element is connected to the input end of the first high-pressure pump, and the output end of the first high-pressure pump is connected to the reverse osmosis unit.

[0053] In operation, water in the tank is pressurized by a first booster pump and flows into the heating element. The heated water is then pressurized by a first high-pressure pump and flows into the reverse osmosis unit for treatment, yielding deionized water. Since the reverse osmosis membrane in the reverse osmosis unit shrinks at low water temperatures, leading to a decrease in water production, this application incorporates a heating element to heat the water flowing into the reverse osmosis unit. This prevents the water flowing into the reverse osmosis membrane from being too cold, thus avoiding membrane shrinkage and increasing water production.

[0054] According to some embodiments of this application, Figure 1 This is a schematic diagram of the water supply system in this application. Figure 2 for Figure 1 A partial schematic diagram in the image. Figure 3 for Figure 1 A partial schematic diagram in the image. Figure 4 for Figure 1 A partial schematic diagram in the image. Figure 5 for Figure 1 A partial schematic diagram. For example... Figures 1-5 As shown, this application provides a water supply system, which includes a water tank 12, a first booster pump 13, a heating element 15, a first high-pressure pump 18, and a reverse osmosis element 20. The input end of the first booster pump 13 is connected to the water tank 12, the output end of the first booster pump 13 is connected to the input end of the heating element 15, the output end of the heating element 15 is connected to the input end of the first high-pressure pump 18, and the output end of the first high-pressure pump 18 is connected to the reverse osmosis element 20.

[0055] In this embodiment, the heating element 15 can be a plate heat exchanger, a water heater, etc. The specific type can be determined according to the actual situation, and this embodiment does not limit it.

[0056] In this embodiment, the reverse osmosis component 20 is a reverse osmosis device. The reverse osmosis device mainly filters water through a reverse osmosis membrane. The water treated by the reverse osmosis membrane is called pure water, which flows out through the outlet 21 in the pure water pipe. The solutes and ions that cannot pass through the reverse osmosis membrane are called concentrated water, which is guided to the concentrated water pipe for discharge.

[0057] refer to Figure 2 and combined Figure 3 As shown, after the water tank 12 and the first booster pump 13 are connected, the first booster pump 13 is connected to the input end of the heating element 15 through the first pipe 24, as follows. Figure 4 As shown, the output end of the heating element 15 is connected to the first high-pressure pump 18 through the second pipe 27, as... Figure 5 As shown, the first high-pressure pump 18 is then connected to the reverse osmosis unit 20 through the third pipe 31.

[0058] refer to Figure 2 As shown, in this embodiment, a third control valve 23 is provided on the first pipe 24, which facilitates the control of the opening or closing of the first pipe 24.

[0059] In the technical solution of this application embodiment, the water in the water tank 12 is pressurized by the first booster pump 13 and flows into the heating element 15 for heating. The heated water is pressurized by the first high-pressure pump 18 and flows into the reverse osmosis element 20 for treatment. At this time, the heated high-pressure water flows through the reverse osmosis membrane in the reverse osmosis element 20 to obtain deionized water.

[0060] Since the reverse osmosis membrane in the reverse osmosis unit 20 will shrink when the water temperature is low, resulting in a decrease in water production, this application provides a heating element 15 to heat the water flowing into the reverse osmosis unit 20. In this way, the water temperature flowing into the reverse osmosis membrane in the reverse osmosis unit 20 can be avoided to prevent the reverse osmosis membrane from shrinking, thereby increasing the water production.

[0061] According to some embodiments of this application, such as Figure 1 and combined Figure 3 As shown, the water supply system also includes a first bypass pipe 16, one end of which is connected to the first booster pump 13, and the other end of which is connected to the first high-pressure pump 18.

[0062] In this embodiment, one end of the first bypass pipe 16 is connected to the first pipe 24, and the other end of the first bypass pipe 16 is connected to the first high-pressure pump 18. The first bypass pipe 16 and the heating element 15 form a parallel structure. When the water temperature in the water tank 12 is high, it is not necessary to heat the water through the heating element 15. At this time, the heating element 15 is turned off, and the water flows through the water tank 12, the first booster pump 13, the first pipe 24, and the first bypass pipe 16 before flowing into the first high-pressure pump 18.

[0063] According to some embodiments of this application, such as Figure 1 and combined Figure 4 As shown, the water supply system also includes a first filter 17, which is disposed between the heating element 15 and the first high-pressure pump 18, or the first filter 17 is disposed between the first bypass pipe 16 and the first high-pressure pump 18.

[0067] A reducing agent is added through the first dosing port 28. The reducing agent reduces the oxides in the water, thereby reducing the oxidizing properties of the water and improving its quality.

[0068] Meanwhile, oxides and other impurities in the water accumulate on the reverse osmosis membrane, forming fouling and membrane contamination. This leads to a shortened membrane lifespan and reduced desalination efficiency. Reducing agents can help clean the reverse osmosis membrane and reduce membrane fouling. Reducing agents can reduce oxides and organic matter on the membrane, converting them into easily cleanable inorganic salts and water, thereby extending the membrane's lifespan and improving desalination efficiency.

[0074] The second high-pressure pump 19 is designed as a redundancy. During normal operation, the first high-pressure pump 18 is started and the second high-pressure pump 19 is turned off. When the first high-pressure pump 18 fails, the second high-pressure pump 19 can be started to ensure the normal operation of the overall system.

[0076] In this embodiment, one end of the second bypass pipe 30 is connected to the second pipe 27, and the other end is connected to the first high-pressure pump 18 and the second high-pressure pump 19.

[0077] When in use, if the water quality is good and there is no need to filter through the first filter 17, the first filter 17 is turned off. At this time, the water flow is directly delivered to the first high-pressure pump 18 and the second high-pressure pump 19 through the second bypass pipe 30.
