Description

Technical Field

[0001] The invention relates to the technical field of electrically driven membrane separation, and in particular to an electrically driven membrane separator testing device. Background Art

[0002] Electrodialysis is an electrochemical separation process that follows Faraday's law. It is a membrane process that separates charged ions from uncharged groups in a solution through a selective ion exchange membrane under the action of a DC electric field with potential difference as the driving force.

[0003] An electrically driven separator is a device that uses membrane separation technology to separate and concentrate solutions. It consists of electrodes, ion exchange membranes, and clamping devices. It uses the characteristics of electrodialysis desalination to remove inorganic electrolytes from certain chemical, pharmaceutical, food and other products to achieve the purpose of separation, purification, extraction and refining.

[0004] The electric drive separator needs to be tested before delivery to identify and solve problems in order to improve the stability of the equipment and reduce equipment failures and maintenance costs.

[0005] The utility model patent document with the existing announcement number CN220550028U discloses an electrically driven membrane separator testing device, which combines the flow channel partition and the ion exchange membrane into an ion exchange membrane by setting a flow channel partition. During the test, the electrically driven membrane separation mechanism is subjected to repeated electrodialysis separation operations, and the deformation state of the ion exchange membrane is observed after stopping. Since the frame of the flow channel partition is widened, a guide hole is opened on the frame, and a guide rod is passed through the guide hole and fixed on an iron clamping plate, the gravity exerted on the ion exchange membrane is distributed to the guide rod, thereby reducing the influence of the weight of the ion exchange membrane and the absorbed liquid on the ion exchange membrane, effectively protecting the ion exchange membrane from deformation, and increasing the service life of the electrically driven membrane separation mechanism.

[0006] Although the above-mentioned electrically driven membrane separator testing device can solve the corresponding technical problems, it can only test the deformation resistance of the ion exchange membrane. The test content is relatively small, and it is difficult to discover other problems of the electrically driven membrane separator and to ensure that the electrically driven membrane separator can operate stably after formal delivery. Therefore, an electrically driven membrane separator testing device is proposed. Summary of the invention
