When the ion membrane assembly in the electrodialysis device needs to be cleaned, the first valve 2, the second valve 6 and the power pump 5 are opened, and after the water in the pipeline is discharged, there is enough space in the pipeline to allow the power pump 5 to act , allowing the required cleaning medium to enter the concentrated water chamber in the electrodialysis device 4 to clean the ion membrane assembly. After passing in the cleaning medium of required concentration, close the first valve 2 and the second valve 6, let the power pump 5 continue to work, make the cleaning medium mix evenly in the concentrated water chamber, then close the power pump 5, let the cleaning medium flow in the concentrated water chamber Stand still in the middle to remove impurities such as scale on the side of the concentrated water chamber of the ionic membrane module. After the reaction, when the concentration of the cleaning medium at different positions is not uniform, the power pump 5 can be restarted to mix evenly, and then the static reaction can be carried out. Specifically, whether the mixture is uniform again and the number of times of mixing uniformly can be confirmed according to requirements. After standing still for sufficient reaction, open the second valve 6 to allow the cleaning medium mixed with impurities to flow out to achieve the purpose of cleaning the ionic membrane module.

When adjusting the state, adjust the concentration of the cleaning medium according to actual needs; in the uniform state, let the cleaning medium mix evenly in the electrodialysis device 4, so that the subsequent static reaction effect is better; The scale on the surface is fully reacted; in the flushing state, the cleaning medium and the scale mixed therein are discharged from the electrodialysis device 4 through the flushing medium. After the flushing is completed, the second valve 6 and the power pump 5 are closed, and the electrodialysis device 4 can use again.

Furthermore, the ionic membrane cleaning system needs to go through several uniform states and reaction states between the adjustment state and the flushing state. Specifically, the ionic membrane cleaning system needs to go through the uniform state and the reaction state at least twice between the adjustment state and the flushing state. After the first reaction, cleaning at different positions The reaction degree of the medium is inconsistent, so it is necessary to turn on the power pump 5 to mix evenly and then fully react again, so that the cleaning effect is better, the scale is removed more effectively, and the life of the ionic membrane is extended. According to actual needs, several uniform states and reaction states can be arranged between the adjustment state and the flushing state, so as to clean the ion membrane components in the electrodialysis device 4 .

Further, the duration of the adjustment state is greater than or equal to 30 seconds, the duration of the uniform state is greater than or equal to 5 minutes, and the duration of the reaction state is greater than or equal to 15 minutes.
