Description

Technical Field

[0001] The utility model relates to the technical field of ultrapure water machines, in particular to an ultrapure water machine with a TOC degradation function. Background Art

[0002] In the early days, the demand for ultrapure water mainly came from industries such as power generation, pharmaceutical chemicals, and papermaking. The water quality requirements were relatively low, and the total organic carbon content in pure water was high. With the development of the semiconductor industry, the quality requirements for ultrapure water have increased, which has greatly promoted the development of ultrapure water technology. The semiconductor industry and the electronics industry have strict requirements for residual organic matter in ultrapure water, generally expressed in terms of total organic carbon. The existing organic matter removal process design for ultrapure water in the semiconductor and electronics industries is as follows: nitrogen-sealed ultrapure water tank, delivery pump, TOC (total organic carbon) degrader, polishing bed, UV (ultraviolet) sterilizer, terminal filter, and ultrapure water is delivered to the point of use and then circulated back to the nitrogen-sealed water tank.

[0003] Since the ultrapure water system can only work more stably at a certain temperature, and there is a large temperature difference between the upper water flowing back and the water accumulated at the bottom, the inlet water temperature has a certain impact on the performance of the ultrapure water system, especially the reverse osmosis membrane's requirements for the inlet water temperature. Too high or too low inlet water temperature will affect the water production of the reverse osmosis membrane. When the temperature increases by 1°C, the water permeability of the ultrapure water system membrane increases by about 2.7%. The lower limit of the inlet water temperature of the reverse osmosis membrane of the ultrapure water system is 5°C-8°C, and the percolation rate is very slow at this time. When the temperature rises to 30°C, the water production increases by 50%. Therefore, an ultrapure water machine with TOC degradation function that controls the temperature of the ultrapure water tank is provided. Summary of the invention
