[0002] In the production process of electronic-grade isopropanol, to ensure product quality, it needs to be strictly filtered by filter element to remove the tiny particulate matters therein. These particulate matters can come from raw materials, equipment or production environment, and if not effectively filtered, it will seriously affect the performance and stability of the final product.
[0003] In order to improve production efficiency and reduce cost, electronic-grade isopropanol filter element needs to be prewashed before use. Pre-washing can effectively remove impurities and residues that may exist in the filter element, reducing the extension of on-line time caused by filter element pollution during formal use. At the same time, pre-washing can also reduce the cost of using electronic-grade isopropanol on the production line, because the pre-washed filter element can reach a stable working state more quickly, reducing downtime and material waste caused by filter element replacement. Therefore, a pre-washing device for filtering electronic-grade isopropanol filter element is proposed. SUMMARY
