一种换流阀均压电极再生装置及方法
摘要：
本发明公开了一种换流阀均压电极再生装置及方法，包括与换流阀内冷水循环水路并联的离子交换旁路；离子交换器串联在离子交换旁路的入口和出口之间的管路上；离子交换器的入口处安装有第一电导率表，离子交换器的出口处安装有第二电导率表；计量泵的入口连接电解质溶液槽，出口连通第二电导率表与离子交换旁路出口之间的管路；计量泵的出口处安装有第三电导率表。本发明通过向内冷水添加电解质，控制内冷水的电导率及电极的析气反应，生成的气体能去除电极表面生成的沉积物，沉积物最终通过离子交换树脂吸附去除，从而实现电极的再生。
摘要（英）：

The invention discloses a converter valve voltage-sharing electrode regeneration device and method. The device comprises an ion exchange bypass connected with an internal cooling water circulation waterway in a converter valve in parallel. An ion exchanger is connected to a pipeline between an inlet and an outlet of the ion exchange bypass in series. An inlet of the ion exchanger is provided with a first conductivity meter, and an outlet of the ion exchanger is provided with a second conductivity meter. An inlet of a metering pump is connected with an electrolyte solution tank, and an outlet of the metering pump is communicated with a pipeline between the second conductivity meter and the outlet of the ion exchange bypass. The outlet of the metering pump is provided with a third conductivity meter. According to the converter valve voltage-sharing electrode regeneration device and method, by adding electrolyte into internal cooling water, the conductivity of the internal cooling water and the gassing reaction of an electrode can be controlled, deposit generated on the surface of the electrode can be removed by generated gas and is finally removed through adsorption of ion exchange resin, and thus the electrode can be regenerated.
