Method and device for controlling water quality of cooling water in converter valve

The invention discloses a method and a device for controlling water quality of cooling water in a converter valve, and the method comprises the following steps: processing the cooling water in the converter valve by using an EDI module bypass, sending the obtained produced water back to a cold water tank in the converter valve, sending the obtained concentrated water and polar water to a circulating water tank, and degassing by using a degassing device; the degassed internal cooling water is treated through an ion exchanger, the treated deionized internal cooling water is sent to an EDI module, and qualified EDI produced water is obtained. The device comprises a converter valve inner cold water tank, an EDI module, a circulating water tank, a degassing device and an ion exchanger. The method and the device can remove impurities in the internal cooling water of the converter valve, enable the water quality of the internal cooling water to be stable, solve the problems that ion exchange resin cannot be replaced
