Title:
ELECTRODEIONIZATION WATER PURIFICATION DEVICE AND HOUSEHOLD WATER PURIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/033205
Kind Code:
A1
Abstract:
Disclosed are an electrodeionization water purification device and a household water purification device. The electrodeionization water purification device comprises an electrodialysis component and at least two electrode components. The electrodialysis component is located between the two electrode components. The electrodialysis component comprises several anion exchange membranes and several cation exchange membranes. The cation exchange membranes and the anion exchange membranes are alternately arranged. The cation exchange membranes are heterogeneous membranes. At least one of the anion exchange membranes is a homogeneous membrane or a semi-homogeneous membrane. At least one of the anion exchange membranes easy to scale is replaced with a homogeneous membrane or a semi-homogeneous membrane for improving the electrochemical performance of the anion exchange membranes; at the same time, the cation exchange membranes not easy to scale are replaced with heterogeneous membranes, so that the anion exchange membranes are not prone to scale without obviously increasing the manufacturing cost, which greatly improves the performance of the electrodeionization water purification device.
