Description

Technical Field

[0001] The present invention relates to the technical field of industrial ultrapure water, in particular to industrial ultrapure water equipment. Background Art

[0002] Ultrapure water, also known as UP water, is commonly used in the integrated circuit industry for cleaning semiconductor raw materials and utensils used, preparing photolithography masks, and as a water vapor source for silicon wafer oxidation. In addition, ultrapure water is also used in the production of other solid-state electronic devices, thick and thin film circuits, printed circuits, and vacuum tubes. To produce ultrapure water with minimal impurities, it is necessary to treat the water using a variety of methods, including coarse filtration, membrane filtration, ultrafiltration filter filtration, UV sterilization, and organic matter removal. Due to the complex and lengthy process involved in ultrapure water treatment, impurities trapped during the filtration process can easily accumulate in pipes and equipment after prolonged operation of the ultrapure water treatment system. This reduces ultrapure water production efficiency, increases the equipment's production load, and reduces the quality of the produced ultrapure water. To ensure the long-term, stable operation of the ultrapure water production system, the equipment must be cleaned regularly. Existing ultrapure water production equipment typically relies on the addition of coagulants and flocculants to form suspended flocs from impurities, and then scrapes off waste residue to treat the water.

The fine particles in the pure water are adsorbed and driven to float up, making it easy to scrape them off. A sewage discharge component 85 is installed on the upper end of the flotation port 84. The sewage discharge component 85 can clean the impurities deposited at the lower end of the tank body 81. A second scraping component 87 is installed on the upper end of the sewage discharge component 85. A second sewage discharge port 86 is symmetrically provided on both side walls of the tank body 81. The height of the second sewage discharge port 86 is level with the second scraping component 87. The second scraping component 87 is responsible for scraping off the fine particles of impurities brought up by the bubbles and discharging them from the second sewage discharge port 86.
