Description

Technical Field

[0001] This utility model relates to the field of pure water devices, and in particular to a pure water device based on concentrated water reuse. Background Technology

[0002] A pure water unit is a water treatment device that combines electrodialysis and ion exchange technologies. It is mainly used to produce high-purity industrial water. The unit achieves a continuous deionization process through modular design, has the characteristics of small footprint, and eliminates the need for traditional mixed bed and regeneration devices.

[0003] Currently, pure water devices produce concentrated water during the pure water production process, which is usually discharged directly. This direct discharge of concentrated water pollutes the environment, and the water utilization rate of pure water devices is low, as they cannot be recycled. Therefore, a pure water device based on concentrated water reuse is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pure water device based on concentrated water recycling, which solves the problem that the concentrated water generated by current pure water devices is not easy to recycle.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A pure water device based on concentrate reuse includes:

[0007] Multiple pure water devices are interconnected, and a circulation pipe connects the output end of one of the pure water devices to the input end of another pure water device.

[0008] A security filter is installed on the circulation pipeline. A high-pressure pump is installed on the circulation pipeline between the security filter and the input end of the pure water device. A first solenoid valve is also provided on the circulation pipeline between the high-pressure pump and the security filter.

[0009] Furthermore, a first shut-off valve is provided at the location of the circulation pipe near the input end of the pure water device.

[0010] Furthermore, a third shut-off valve is provided at the location of the circulation pipeline near the output end of the pure water device.

[0011] Furthermore, a check valve is provided in the circulation pipeline between the third shut-off valve and the security filter.

[0012] Furthermore, the circulation pipe is connected to a first auxiliary pipe at the output end of the pure water device.

[0013] Furthermore, a ball valve and a second solenoid valve are installed on the first secondary pipe, and the ball valve and the second solenoid valve are arranged close to each other.

[0014] Furthermore, a second shut-off valve is also provided on the first secondary pipe, and the second shut-off valve is located on the side close to the second solenoid valve.

[0015] Furthermore, the first secondary pipe is connected to a water inlet, which is located between the second shut-off valve and the second solenoid valve.

[0016] Furthermore, the circulation pipe is connected to a second auxiliary pipe between the check valve and the security filter, and a heater is installed on the second auxiliary pipe.

[0017] Furthermore, a storage box is connected to the second auxiliary pipe.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By using a pure water device and a security filter, along with a high-pressure pump and a first solenoid valve, the concentrated water (wastewater) produced after the raw water passes through the pure water device returns to the security filter. The security filter performs coarse filtration on the incoming concentrated water, blocking particulate matter in the water and preventing damage to the reverse osmosis membrane. Then, it passes through the first solenoid valve and the high-pressure pump. The high-pressure pump generates pressure to allow the concentrated water to circulate, so that the concentrated water is reprocessed by the pure water device. After treatment, it is discharged. This reprocessing of the concentrated water prevents environmental pollution while improving the water utilization rate of the pure water device.

[0020] 2. Through the second auxiliary pipe, in conjunction with the heater and storage tank, when the pollution caused by the discharge of concentrated water is too great, the concentrated water can be allowed to enter the interior of the heater. The heater heats the concentrated water, causing it to evaporate. The crystallized concentrated water after evaporation can be easily processed by the staff, and the storage tank can store the generated steam. Attached Figure Description

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] This utility model embodiment provides a pure water device based on concentrated water reuse. Please refer to [link / reference]. Figure 1It includes: multiple pure water devices 5, which are interconnected; a circulation pipe is connected between the output end of one of the pure water devices 5 and the input end of another pure water device 5; a security filter 1 is installed on the circulation pipe; a high-pressure pump 3 is installed between the security filter 1 and the input end of the pure water device 5; and a first solenoid valve 2 is also provided on the circulation pipe, which is located between the high-pressure pump 3 and the security filter 1.

[0030] like Figure 1 As shown, multiple pure water devices 5 are interconnected to form an integrated pure water preparation system, which can increase the amount of pure water prepared and the processing capacity. Different pure water devices 5 can work together in the system and flexibly adjust their operating status according to actual needs.

[0031] The circulation pipeline forms a path for the return of concentrated water, drawing some of the concentrated water from the output end back to the input end, thus realizing the recycling of concentrated water. The concentrated water contains a certain amount of impurities and dissolved substances that have not been completely separated. By recirculating, these substances can be treated again through the pure water device 5, thereby improving the utilization rate of water resources.

[0032] Security filter 1 is mainly used to intercept particulate impurities larger than its filtration precision in the circulating pipeline, such as suspended solids and colloids. It can perform coarse filtration on the incoming concentrated water, block particulate matter in the water, prevent the reverse osmosis membrane from being scratched, prevent these impurities from causing wear and blockage to the equipment, and protect the normal operation of the equipment.

[0033] The high-pressure pump 3 provides power for the flow of concentrated water in the circulation pipeline, enabling it to overcome pipeline resistance and system pressure and smoothly return to the input end of the pure water device 5. At the same time, the high-pressure pump 3 can increase the water pressure to meet the inlet pressure requirements of the pure water device 5 and ensure that the pure water device 5 can operate normally.

[0034] The first solenoid valve 2 is mainly used to control the flow of concentrated water in the circulation pipeline. By controlling the opening and closing of the first solenoid valve 2, the return flow of concentrated water can be flexibly adjusted, and the operating parameters of the system can be adjusted according to actual needs.

[0035] Specific operating process: Open the inlet and inject raw water into the system. The raw water enters the circulation pipe through the first auxiliary pipe. When the water level reaches a certain requirement, open the first solenoid valve 2 to allow the concentrated water to flow in the circulation pipe. Start the high-pressure pump 3. The high-pressure pump 3 pressurizes the concentrated water and sends it to the security filter 1 for filtration to remove particulate impurities. The filtered concentrated water enters the input end of the pure water device 5 and participates in the pure water preparation process again. The concentrated water produced by the pure water device 5 can re-enter the security filter 1 and then enter the interior of the pure water device 5 through the high-pressure pump 3 for further treatment, completing the circulation.

[0036] Please continue reading. Figure 1A first shut-off valve 4 is provided near the input end of the pure water device 5 in the circulation pipeline, a third shut-off valve 9 is provided near the output end of the pure water device 5 in the circulation pipeline, and a check valve 10 is provided between the third shut-off valve 9 and the security filter 1 in the circulation pipeline.

[0037] like Figure 1 As shown, the first shut-off valve 4 plays a crucial role in precisely controlling the flow of water into the pure water device 5 within the circulating pipeline system. It can completely cut off or allow the water flow, thus controlling the opening and closing of the process of concentrated water returning to the pure water device 5. When maintenance, repair, or system operation mode adjustment of the pure water device 5 is required, the first shut-off valve 4 can be closed to prevent concentrated water from entering the pure water device 5, avoiding unnecessary interference or damage to the equipment.

[0038] During normal system operation, the first shut-off valve 4 can also work with other valves to adjust the flow rate of concentrated water entering the pure water device 5, thereby affecting the efficiency and quality of pure water preparation. For example, by appropriately reducing the opening of the first shut-off valve 4, the flow rate of concentrated water entering the pure water device 5 can be reduced, the circulation time of concentrated water in the system can be extended, and impurities can be separated more fully, thereby improving the quality of pure water.

[0039] The third shut-off valve 9 is mainly used to control the water flow from the output end of the pure water device 5. It can cut off or regulate the water flow at the output end. On the one hand, when the system needs to stop the return of concentrated water or to maintain the related equipment at the output end, closing the third shut-off valve 9 can prevent water leakage and ensure the system's sealing. On the other hand, by adjusting the opening of the third shut-off valve 9, the pressure and flow distribution in the circulation pipeline can be controlled. For example, appropriately reducing the opening of the third shut-off valve 9 can increase the pressure in the circulation pipeline, which is beneficial to improving the circulation power of concentrated water in the system. At the same time, it can also affect the filtration effect of equipment such as the security filter 1.

[0040] The main function of check valve 10 is to prevent backflow of water. In the circulation pipeline, when high-pressure pump 3 stops running or the system pressure changes, concentrated water may flow back. Check valve 10 ensures that concentrated water can only flow from the output of pure water device 5 through the third shut-off valve 9 and check valve 10 to the security filter 1, avoiding backflow that could damage pure water device 5 and other equipment.

[0041] Please continue reading. Figure 1 The circulation pipe is connected to the first secondary pipe at the output end of the pure water device 5. A ball valve 6 and a second solenoid valve 7 are installed on the first secondary pipe. The ball valve 6 and the second solenoid valve 7 are set close to each other. A second shut-off valve 8 is also provided on the first secondary pipe. The second shut-off valve 8 is set on the side close to the second solenoid valve 7. A water inlet is connected to the first secondary pipe. The water inlet is located between the second shut-off valve 8 and the second solenoid valve 7.

[0042] like Figure 1 As shown, the first auxiliary pipe provides an additional fluid channel for the entire pure water device 5 system. It is led out from the circulation pipe at the output end of the pure water device 5, which allows the water flow output from the pure water device 5 to be diverted. This diversion design increases the flexibility of system operation and can treat or guide the water flow differently according to different needs.

[0043] Ball valve 6 is a commonly used manually controlled valve that controls the flow of fluid by rotating a ball. Installing ball valve 6 on the first auxiliary pipe allows for convenient manual opening or closing of the fluid passage. For simple operations such as temporarily stopping the water flow in the first auxiliary pipe or manually adjusting the flow rate, ball valve 6 provides a quick and direct control method. The second solenoid valve 7 is an electrically controlled valve that automatically opens or closes based on electrical signals. It enables remote control and automated operation. Working in conjunction with ball valve 6, for example, in some automated production processes, the flow of water in the first auxiliary pipe can be precisely controlled by controlling the second solenoid valve 7 based on preset programs or sensor feedback signals, improving the system's automation level and operating efficiency. Furthermore, concentrated wastewater can be discharged through both ball valve 6 and the second solenoid valve 7.

[0044] Overall flow process: Security filter 1 → First solenoid valve 2 → High pressure pump 3 → First shut-off valve 4 → Pure water device 5 → Third shut-off valve 9 → Check valve 10 → Security filter 1 → First solenoid valve 2 → High pressure pump 3 → First shut-off valve 4 → Pure water device 5 → Ball valve 6 → Second solenoid valve 7 (discharge).

[0045] The second shut-off valve 8 is mainly used to precisely regulate the fluid flow rate in the first auxiliary pipe. Unlike the on / off control of the ball valve 6, the shut-off valve can control the flow rate by adjusting the opening of the valve disc. Based on the control of water flow by the second solenoid valve 7, the second shut-off valve 8 can further fine-tune the flow rate to meet more precise production needs.

[0046] The design of the inlet allows external water sources to be easily connected to the first secondary pipe. When the system needs to replenish water or introduce new fluid, water can be injected into the first secondary pipe through the inlet. The inlet is located between the second shut-off valve 8 and the second solenoid valve 7. When injecting water, the flow rate can be controlled by the second shut-off valve 8, while the injection time and on / off can be controlled by the second solenoid valve 7.

[0047] Please see Figure 2 The circulation pipeline is located between the check valve 10 and the security filter 1 and is connected to a second auxiliary pipe. A heater 11 is installed on the second auxiliary pipe, and a storage tank 12 is connected to the second auxiliary pipe.

[0048] like Figure 2 As shown, the second branch pipe opens up a new branch for the water flow in the circulation pipe, allowing some water to be diverted from the main circulation path, undergo special treatment through the second branch pipe, and then return to the system or be used for other purposes. This diversion design increases the system's flexibility and operability, enabling targeted treatment of the water flow according to different needs.

[0049] Heater 11 can heat the water flowing through the second auxiliary pipe. In some specific applications, such as when the pollution caused by the discharge of concentrated water is too great, the concentrated water can enter the interior of heater 11. Heater 11 heats the concentrated water and causes it to evaporate. The crystallized concentrated water after evaporation can be easily processed by the staff. The storage tank 12 can store the generated steam.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
