[0032] Please see Figure 1-8Ultrapure water membrane filtration equipment is a high-precision water treatment technology widely used in semiconductor, pharmaceutical, electronics, and laboratory fields. When using this type of equipment, although the raw water undergoes pretreatment, if appropriate sterilization measures are not taken during the filtration process, microorganisms may proliferate inside the membrane system, leading to biofilm formation. Biofilm not only reduces the membrane's filtration efficiency but may also become a source of secondary water pollution. Chemical treatment methods, such as heating, can easily damage the filter membrane, while physical filtration methods, such as ultraviolet disinfection, may result in incomplete disinfection due to excessive water flow. Therefore, this application provides an ultrapure water membrane filtration device, including a support frame 1, with a reverse osmosis component 2 arranged inside the frame 1 for filtration.

[0033] The reverse osmosis assembly 2 includes a pressure pump 21 that provides pressure and a filter assembly 23. The filter assembly 23 is connected to the pressure pump 21 via a pipe 22, and there are one or more filter assemblies 23. Each pair of filter assemblies 23 is also connected via a pipe 22.

[0034] The filter assembly 23 includes a pressure housing 231 and a filter element disposed inside it. The pressure housing 231 has an inner cavity 233 on its inner side, and the inner cavity 233 is adapted to the filter element.

[0035] The inner side of the inner cavity 233 is provided with one or more sets of lamp plates 234 and insertion tubes 237 arranged in a ring array. The lamp plates 234 and the filter element maintain a fixed distance. The insertion tubes 237 are inserted into the filter element to fix the filter element.

[0036] Frame 1 is the main structure of the device, used to support the entire system, including the installation and fixing of all components.

[0037] Pressure pump 21 provides the necessary pressure for the filtration process, ensuring that impurities and microorganisms are effectively separated when water flows through the filter element.

[0038] The filter assembly 23 consists of a pressure housing 231 and an internal filter element, used in the actual water filtration process. Multiple filter assemblies 23 can be connected in series or parallel via pipes 22 to increase processing capacity and efficiency.

[0039] The pressure housing 231 includes an inner cavity 233 designed to match the filter element, ensuring proper installation and sealing of the filter element.

[0040] Filter cartridges are responsible for filtering impurities and microorganisms from water. The materials and structure of the filter cartridges are selected based on the required filtration precision.

[0041] The lamp panels 234 are arranged in a ring array in the inner cavity 233, maintaining a certain distance from the filter element. These lamp panels 234 are usually equipped with ultraviolet lamps for disinfecting the filtered water, and the connector 237 is used to fix the filter element and ensure its stable position within the pressure housing 231.

[0042] After the raw water has been pretreated, it enters the pressure pump 21 through the pipeline 22, and after being pressurized, it enters the filter assembly 23.

[0043] Water flows through the filter cartridge, where impurities and microorganisms are trapped, and the purified water is collected and output.

[0044] The UV lamp panel 234 emits ultraviolet light to disinfect the water flowing through the filter cartridge.

[0045] The fixed spacing between the lamp panel 234 and the filter element ensures that ultraviolet light can effectively cover the water flow, improving disinfection efficiency.

[0046] The insert pipe 237 secures the filter element inside the pressure housing 231 to prevent it from shifting or being damaged under water pressure. The insert pipe 237 is connected to a chemical treatment agent through an interface extending to the outside. Decomposable hydrogen peroxide is used for disinfection, which can decompose into water and oxygen under certain conditions without leaving any harmful residues.

[0047] By integrating a UV disinfection system, disinfection can be carried out simultaneously during the filtration process, effectively controlling microbial contamination and reducing biofilm formation.

[0048] Compared to traditional chemical disinfection methods, ultraviolet disinfection does not damage the filter material and extends the filter's lifespan.

[0049] The combined use of multiple filter components 23 allows for adjustment of the treatment capacity as needed, adapting to water treatment requirements of different scales.

[0050] The design of the ring array lamp panel 234 allows ultraviolet light to be evenly distributed around the water flow, improving the uniformity and effectiveness of disinfection. The filter element is fixed by the insertion pipe 237, which is convenient for replacement and cleaning, and easy to maintain.

[0051] The combination of ultraviolet disinfection and hydrogen peroxide does not introduce any chemicals, ensuring the purity of the effluent and meeting the requirements for ultrapure water.

[0052] The light panel 234 includes an outer frame 2341, an inner cavity 2344 is provided on the inner side of the outer frame 2341, a light strip 2343 is provided on the inner side of the mounting cavity 2344, and a light-transmitting plate is covered on the outer side of the outer frame 2341 through a waterproof groove 2342.

[0053] As the supporting structure of the lamp panel 234, the outer frame 2341 needs to have sufficient strength and stability to withstand the pressure and environmental conditions inside the filter assembly 23.

[0054] The outer frame 2341 is typically made of corrosion-resistant and high-temperature-resistant materials, such as stainless steel or special plastics, to adapt to water treatment environments.

[0055] Mounting cavity 2344 is located inside the outer frame 2341 and is used to house the light strip 2343. The design of mounting cavity 2344 should facilitate the installation and replacement of light strip 2343. Mounting cavity 2344 may include a snap-fit ​​or bolt fixing mechanism to ensure that light strip 2343 is secure and easy to maintain.

[0056] The light strip 2343 is equipped with ultraviolet LED beads that emit ultraviolet light to disinfect the water flowing through it.

[0057] A waterproof groove 2342 is provided on the outer side of the outer frame 2341 for installing the light-transmitting plate and ensuring the overall sealing of the lamp panel 234 to prevent moisture from seeping into the mounting cavity 2344. The waterproof groove 2342 may use O-rings or other seals to enhance the sealing effect.

[0058] A light-transmitting panel, made of a light-transmitting material, covers the outside of the waterproof groove 2342, allowing ultraviolet rays to pass through while protecting the internal light strip 2343 from moisture and impurities.

[0059] The light-transmitting panel should be made of UV-resistant and high-temperature resistant materials, such as quartz glass or special plastics, to ensure light transmittance and durability for long-term use.

[0060] Working principle

[0061] The ultraviolet lamp beads in the light strip 2343 emit ultraviolet rays, which are irradiated onto the water flow inside the filter assembly 23 through the light-transmitting plate.

[0062] Ultraviolet light damages the DNA structure of microorganisms in water, rendering them unable to reproduce, thereby achieving disinfection.

[0063] The waterproof groove 2342 and the light-transmitting plate ensure that the light strip 2343 is protected from moisture, maintaining its normal operation and extending its service life.

[0064] By directly installing the ultraviolet lamp plate 234 inside the filter component 23, the water flow is fully exposed to ultraviolet light, thereby improving the disinfection efficiency.

[0065] The combination of the waterproof groove 2342 and the light-transmitting plate effectively prevents moisture from entering the installation cavity 2344, protects the light strip 2343 from moisture, and extends its service life. The design of the light strip 2343 and the light-transmitting plate makes it easy to disassemble and replace, and facilitates cleaning and maintenance. The light-transmitting plate, made of high-transmittance material, ensures that ultraviolet rays can effectively penetrate into the water, improving the disinfection effect.

[0066] A sealing groove 232 is provided on one side of the pressure housing 231, and a pressure cover is provided at the sealing groove 232 for sealing the housing.

[0067] An outlet 238 is provided on the inner side of the inner cavity 233 away from the pressure cover. An installation plate 236 is provided on the outer side of the outlet 238. Mounting seats 235 are arranged in a ring array on the plate body of the installation plate 236. The mounting seats 235 are combined with one of the lamp panels 234.

[0068] One end of the outlet 238 is connected to the pipe 22 to form a delivery pipeline.

[0069] A positioning ring 239 is provided on the outer side of the mounting plate 236. The ring body of the positioning ring 239 is adapted to the insertion tube 237 for fixing the insertion tube 237. One end of the insertion tube 237 extends to the outer side of the inner cavity 233.

[0070] A connection port 2310 is provided on the outer side of the inner cavity 233. The connection port 2310 is connected to the pipe 22 through a sealing element to connect two adjacent pressure shells 231.

[0071] A sealing groove 232 is provided on one side of the pressure housing 231 for installing a pressure cover, ensuring the airtightness of the housing and preventing water leakage and the intrusion of external contaminants.

[0072] The pressure cover mates with the sealing groove 232 to seal the pressure housing 231, and the sealing performance is ensured by a sealing element (such as an O-ring).

[0073] Pressure caps may be equipped with locking devices, such as bolts or clips, to ensure stability under high pressure.

[0074] The inner cavity 233 inside the pressure housing 231 is adapted to the filter element to ensure that the filter element is installed correctly and to make the most of the internal space. The end of the inner cavity 233 away from the pressure cover is provided with an outlet 238 for discharging filtered and disinfected water.

[0075] The outlet 238 is located at one end of the inner cavity 233, and the outer side is connected to the mounting plate 236. The mounting plate 236 is provided with mounting seats 235 in a ring array for fixing a set of lamp plates 234 to achieve ultraviolet disinfection of the area near the outlet 238. The outlet 238 is connected to the subsequent treatment unit or water storage tank through the pipe 22 to form a continuous water treatment and transportation pipeline. The outer side of the mounting plate 236 is provided with a positioning ring 239, which is adapted to the insertion pipe 237 for fixing the filter element.

[0076] One end of the insertion tube 237 extends to the outside of the inner cavity 233, and may be connected to the external fixing structure to further reinforce the position of the filter element.

[0077] The pressure housing 231 has a connection port 2310 on its outer side for connecting to an adjacent pressure housing 231 or pipe 22. A seal is used at the connection port 2310 to ensure the connection is airtight and prevent leakage.

[0078] The pressure housing 231, through the cooperation of the sealing groove 232 and the pressure cover, as well as the seals at each connection, ensures the airtightness of the entire system. The insertion pipe 237 and the positioning ring 239 work together to ensure the stable position of the filter element in the inner cavity 233 and prevent it from moving under water pressure.

[0079] Multiple pressure housings 231 can be connected in series or in parallel through the connection port 2310 and the pipe 22 to form a large-scale water treatment system. The design of the sealing groove 232 and the pressure cover, combined with the use of seals, ensures the sealing performance of the pressure housings 231 and prevents leakage and contamination.

[0080] The combination of the insertion pipe 237 and the positioning ring 239 ensures that the filter element is installed securely, guaranteeing the filtration and disinfection effects. Multiple filter components 23 can be flexibly combined through the connection port 2310 and the pipe 22 to meet the needs of different processing volumes.

[0081] The removable design of the pressure cap facilitates the inspection, cleaning and replacement of internal components. A light panel 234 is installed near the outlet 238 to perform final disinfection treatment on the filtered water, ensuring high-quality water output.
