[0002] In the field of ultrapure water preparation, the application of traditional ultrapure water equipment faces many severe challenges. Traditional ultrapure water equipment usually relies on multi-stage process devices working together to achieve the goal of ultrapure water preparation.

[0003] Existing ultrapure water equipment often needs to go through multiple steps in sequence such as pretreatment, reverse osmosis, ion exchange, ultrafiltration, etc. Each step requires special equipment and elaborate operation procedures. This results in complicated operation processes, which not only imposes strict requirements on the professional skills of operators and increases labor costs, but also brings great difficulty to equipment commissioning and maintenance. Once a link fails, troubleshooting and repair are extremely time-consuming and labor-intensive. Secondly, since each process device needs to occupy a certain amount of space, the combination of numerous devices greatly increases the floor area of the whole ultrapure water equipment.

Figure 2 This is a front view of the integrated ultrapure water process equipment of this utility model, which is small in size and easy to replace. Figure 3 yes Figure 2 For the sectional view along the AA direction, please refer to [link / reference]. Figures 1 to 3The diagram illustrates a preferred embodiment of a compact and easily replaceable integrated ultrapure water process device. It includes an outer shell 1, an inner shell 2, a primary RO membrane filter element 3, a secondary RO membrane filter element 4, and an outlet pipe 5. The inner shell 2 is housed inside the outer shell 1, with the primary RO membrane filter element 3 positioned between the inner shell 2 and the outer shell 1. The outlet pipe 5 is located within the inner shell 2, and the secondary RO membrane filter element 4 is positioned between the outlet pipe 5 and the inner shell 2. A first purified water hole 6 is provided on the side wall of the inner shell 2, and a second purified water hole 7 is provided on the side wall of the outlet pipe 5. A first wastewater outlet is located at the lower end of the outer shell 1. In this embodiment, the inner shell 2, the primary RO membrane filter element 3, the secondary RO membrane filter element 4, and the outlet pipe 5 are integrated within the outer shell 1, significantly reducing the overall space occupied by the device and achieving a compact design. The lower end of the inner shell 2 is fixedly connected to the lower inner wall of the outer shell 1, which can be achieved by welding. A first wastewater outlet is located at the lower end of the outer shell 1, directly opposite the primary RO membrane filter 3. After initial filtration by the primary RO membrane filter 3, the resulting pure water enters the lower side of the secondary RO membrane filter 4 through the first clean water hole 6 and undergoes further filtration within the secondary RO membrane filter 4. The pure water produced after filtration by the secondary RO membrane filter 4 enters the outlet pipe 5 and is then discharged from the upper end of the outlet pipe 5. The wastewater produced after filtration by the primary RO membrane filter 3 is discharged directly from the first wastewater outlet, while the wastewater produced after filtration by the secondary RO membrane filter 4 is discharged from the second wastewater outlet 13.

[0025] Furthermore, as a preferred embodiment, it also includes a first connector 8 and a second connector 9. The first connector 8 is disposed at the upper end of the outer casing 1, and the second connector 9 is disposed inside the first connector 8. The upper end of the water outlet pipe 5 is located inside the second connector 9. A raw water inlet 10 is formed between the first connector 8 and the second connector 9, and a second wastewater outlet 13 is formed between the second connector 9 and the water outlet pipe 5. See also Figure 1 As shown, the first connector 8 is installed at the upper end of the outer shell 1 and can be threadedly connected to the outer shell 1, which facilitates the disassembly of the first connector 8. The lower end of the second connector 9 is located inside the inner shell 2, and the outer wall of the second connector 9 is sealed to the upper inner wall of the inner shell 2. See details. Figure 3As shown, a sealing ring is provided on the outer wall of the second connector 9, which seals against the upper inner wall of the inner housing 2. The second connector 9 is threadedly connected to the upper inner wall of the inner housing 2, facilitating its disassembly and thus the removal or installation of the secondary RO membrane filter element 4. The outlet pipe 5 is directly inserted into the middle of the secondary RO membrane filter element 4, facilitating its installation and removal. The outlet pipe 5 fits tightly against the inner wall of the secondary RO membrane filter element 4, and its lower end is sealed to prevent pure water filtered by the primary RO membrane filter element 3 from directly entering the outlet pipe 5. In this embodiment, the outer wall of the secondary RO membrane filter element 4 is in close contact with the inner wall of the second connector 9.

[0026] Furthermore, as a preferred embodiment, the upper end of the water outlet pipe 5 is a clean water outlet 11, and the clean water entering the water outlet pipe 5 can be discharged through the clean water outlet 11.

[0027] Furthermore, as a preferred embodiment, a water purification passage 12 is formed between the outer wall of the secondary RO membrane filter element 4 and the inner wall of the inner shell 2. The purified water filtered by the primary RO membrane filter element 3 will enter the water purification passage 12 through the first water purification hole 6, and then enter the bottom of the secondary RO membrane filter element 4.

[0028] Furthermore, as a preferred embodiment, the primary RO membrane filter element 3, the secondary RO membrane filter element 4, and the outlet pipe 5 are coaxially arranged. In this embodiment, the primary RO membrane filter element 3 and the secondary RO membrane filter element 4 are installed inside the outer casing 1 in a concentric circle manner, which greatly reduces the size of the equipment.

[0029] Furthermore, as a preferred embodiment, the lower end of the water outlet pipe 5 contacts the lower inner wall of the inner shell 2 to support the water outlet pipe 5.

[0030] In this embodiment, the filtration accuracy of the secondary RO membrane filter element 4 is greater than that of the primary RO membrane filter element 3.

[0031] In use, the first connector 8 can be connected to the external raw water pipe connector, the second connector 9 to the external wastewater pipe connector, and the outlet pipe 5 to the external purified water pipe connector. Raw water enters the primary RO membrane filter element 3 through the raw water inlet 10. After filtration by the primary RO membrane filter element 3, the resulting pure water enters the purified water passage 12 through the first purified water hole 6, and then enters the lower end of the secondary RO membrane filter element 4. The pure water produced by the primary RO membrane filter element 3 serves as the raw water for further filtration within the secondary RO membrane filter element 4. The pure water produced by the secondary RO membrane filter element 4 enters the outlet pipe 5 through the second purified water hole 7, and then exits through the purified water outlet 11 of the outlet pipe 5. Wastewater produced by the primary RO membrane filter element 3 is discharged through the first wastewater outlet at the lower end of the outer casing 1, while wastewater produced by the secondary RO membrane filter element 4 is discharged through the second wastewater outlet 13.

[0032] When it is necessary to replace the primary RO membrane filter element 3 and the secondary RO membrane filter element 4, the first connector 8 and the second connector 9 can be removed, and then the primary RO membrane filter element 3 and the secondary RO membrane filter element 4 can be taken out directly. New primary RO membrane filter elements 3 and 4 can be installed, and then the first connector 8 and the second connector 9 can be installed.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
