Description

Technical Field

[0001] The utility model relates to the technical field of ultrapure water boron removal, in particular to a filtering device for an ultrapure water boron removal device. Background Art

[0002] Ultrapure water refers to highly purified water with extremely low levels of impurities and ions. Ultrapure water is widely used in industry, medicine, scientific research and other fields. In the process of preparing ultrapure water, boron removal is an important step. Boron is a colorless, odorless element that exists in water in a variety of open forms, including boric acid, metaboric acid, sodium tetrahydroxyborate, etc. The basic principle of ultrapure water boron removal is to remove the boron ions dissolved in water by physical or chemical methods. The chemical precipitation method is suitable for treating high-concentration boron-containing wastewater. By adding certain inorganic acids or alkalis to the wastewater, boron is converted into insoluble boric acid or borate to achieve the purpose of separating and extracting boron. The water after chemical precipitation needs to be filtered using a filtration device.

[0003] In the prior art, when a filtration device is used to filter a mixture of water and borate, a small amount of boric acid or borate in the ultrapure water adheres to the filter screen, which affects the flow rate of ultrapure water on the filter screen per unit time over time. The filter screen in the filtration device is not easy to clean, and in the prior art, the device needs to be stopped and the filter screen needs to be disassembled before it can be cleaned, which affects the efficiency of the filtration work.
