AI Technical Summary

Technical Problem

Electrochemical hardening technology faces the problem of cathode scaling in engineering applications, which leads to a decrease in the effective reaction area of ​​the electrode, uneven distribution of reaction current density, increased cell voltage, and increased energy consumption. In addition, traditional cleaning methods are cumbersome and may damage the electrode, making it difficult to meet the requirements of stable industrial operation.

Method used

Electromagnets are integrated on the cathode substrate, and a functional layer of magnetic particles that can be attached and detached is formed on the cathode surface by controlling a gradient magnetic field. A stable three-dimensional functional layer is formed by electrophoretic deposition technology, which enables active control and periodic detachment of magnetic particles, reducing the risk of scaling.

Benefits of technology

It significantly increases the effective reaction area of ​​the electrode, improves the efficiency and rate of electrochemical reaction, reduces energy consumption, simplifies maintenance operations, extends the service life of the cathode, and meets the needs of continuous industrial operation.

Abstract

本发明涉及电化学水处理技术领域，尤其涉及一种用于电化学水处理的阴极、电化学水处理系统和工业废水的除硬方法。该阴极包括：阴极基体，以及集成于该阴极基体的电磁体；电磁体用于在阴极基体的工作表面附近产生梯度磁场，并控制梯度磁场的启闭；梯度磁场用于吸引磁性颗粒在阴极基体的工作表面形成可附着与可脱离的功能层。该阴极通过在基体上集成电磁体，获得了在电极表面主动产生和撤消梯度磁场的能力。电极表面能够按需形成由磁性颗粒构成的功能层，并且当该功能层完成负载沉积后，可以通过撤去磁场，整体从阴极表面移除。从而将沉积界面从电极表面转化为可周期性更换的消耗性界面。由此降低了阴极表面的结垢风险与清洗维护难度，延长了阴极的使用寿命。
