Description

Technical Field

[0001] This utility model relates to the field of ultrapure water storage technology, specifically to an ultrapure water storage tank with ultraviolet sterilization and TOC degradation. Background Technology

[0002] Ultrapure water storage tanks are key equipment in ultrapure water systems, used to store and protect ultrapure water from secondary contamination. Material selection: 304 or 316L stainless steel is recommended. The inner wall must be smooth and free of dead corners, meeting food-grade standards to ensure corrosion resistance and easy cleaning. Sealing and protection: Equipped with a breather or nitrogen sealing device to isolate air and prevent carbon dioxide and bacterial contamination. Nitrogen-sealed tanks maintain positive pressure through nitrogen filling for better results. Structural design: Sanitary connections are used for the tank lid, manhole, etc., facilitating disassembly and cleaning; a drain outlet is designed at the bottom to ensure no water accumulation; high and low level alarms are required for liquid level control. Auxiliary devices: A spray system can be installed on the top to prevent microbial growth; for sterilization, it must be designed according to pressure vessel standards and equipped with a pressure reducing valve or explosion-proof membrane.

[0003] Ultrapure water storage tanks use ultraviolet (UV) sterilization and TOC degradation lamps to sterilize and degrade ultrapure water during storage, reducing contamination during storage. However, the UV sterilization and TOC degradation lamps are consumable parts, prone to damage after prolonged operation. Furthermore, these lamps are independently installed and inserted into the bottom of the storage tank's inner cavity, making quick replacement inconvenient when damaged. To address these issues, this application proposes an ultrapure water storage tank with UV sterilization and TOC degradation capabilities. Utility Model Content

Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] like Figure 1-4 As shown, the present invention proposes an ultrapure water storage tank with ultraviolet sterilization and TOC degradation, including a storage tank 1 and a tank cover 2. The tank cover 2 is fixed to the top of the storage tank 1 by bolts. A lamp mounting seat 3 is integrally formed on the upper surface of the tank cover 2. The bottom of the inner cavity of the lamp mounting seat 3 is provided with insertion holes, which are arranged in an equidistant manner. The inner cavity of the lamp mounting base 3 is provided with a lifting plate 5. A TOC degradable lamp 6 and an ultraviolet lamp 7 are installed at the bottom of the lifting plate 5.

[0019] It should be noted that the tank lid 2 is fixed to the top of the storage tank 1 with bolts, which makes the storage tank 1 a closed structure. Ultrapure water can be stored through the storage tank 1. The tank lid 2 is equipped with a lamp mounting base 3. The top of the lamp mounting base 3 is equipped with a light-transmitting protective tube 8. The top of the light-transmitting protective tube 8 is fixed to the threaded fixing seat 9 by a threaded connector 10, which allows for easy replacement of the light-transmitting protective tube 8. The TOC degradation lamp 6 and the ultraviolet lamp 7 are respectively inserted into the light-transmitting protective tube 8. The TOC degradation lamp 6 is typically designed with a dose of 200 mJ / cm³. 2 In summary, the TOC degradation lamp 6 emits ultraviolet light at a wavelength of 185nm, causing a homolytic reaction in the water to produce active intermediates. These intermediates react with organic matter in the water, degrading it into CO2 and other harmless substances, thereby reducing the TOC concentration in the water. Meanwhile, the ultraviolet lamp 7 uses a wavelength of 254nm to sterilize and disinfect ultrapure water, ensuring the preservation quality of ultrapure water.

[0025] It should be noted that when the TOC degradable lamp tube 6 and the ultraviolet lamp tube 7 are inserted into the insertion hole, the limiting rubber ring 11 can limit the TOC degradable lamp tube 6 and the ultraviolet lamp tube 7 to prevent them from colliding with the inner wall of the light-transmitting protective tube 8 during insertion and removal.

Ultrapure water can be stored through the storage tank 1. The tank lid 2 is equipped with a lamp mounting base 3, and a light-transmitting protective tube 8 is provided on the top of the lamp mounting base 3. The top of the light-transmitting protective tube 8 is fixed by a threaded connector 10 connected to a threaded fixing seat 9, which facilitates the replacement of the light-transmitting protective tube 8. The TOC degradation lamp 6 and the ultraviolet lamp 7 are respectively inserted into the light-transmitting protective tube 8. The TOC degradation lamp 6 is typically designed with a dose of 200 mJ / cm³. 2In summary, the TOC degradation lamp 6 emits ultraviolet light at a wavelength of 185nm, causing a homolytic reaction in the water to produce active intermediates. These intermediates react with organic matter in the water, degrading it into CO2 and other harmless substances, thereby reducing the TOC concentration in the water. The ultraviolet lamp 7 uses a wavelength of 254nm to sterilize and disinfect ultrapure water, ensuring the preservation quality of ultrapure water. After the pressure plate 4 is disassembled, it can be connected to the lifting ring 16 via the hook 17.
