[0002] The ultrapure water preparation device is a device used for the production of ultrapure water. Various impurities in the water can be removed through the ultrapure water device. The treated ultrapure water contains very few impurities and can be used as an ultrapure material.

[0003] When the ultrapure water preparation device is in use, a multi-stage filter element will be used to filter the water. The use of a multi-stage water filter element for filtering can better remove impurities in the water. When in use, a filter element seat will be installed inside the tank and the water filter element will be fixed. During the filtering work, impurities in the water will adhere to the inner wall of the tank, and the staff needs to frequently clean the inner wall of the tank and the filter element seat. When cleaning, the tank and the filter element seat need to be removed, and a special cleaning brush needs to be used to clean the inner wall of the tank. However, due to the long length of the tank, it is difficult for the staff to understand the situation inside the tank during the cleaning process, which can easily lead to cleaning residues. For this reason, we provide an ultrapure water preparation device with a multi-stage filter element to solve the above problems. Utility Model Content
