Switching the refined salt water pump affects caustic soda production
Thread Content
In the electrolysis process, there are two brine pumps. Each time the system switches to Pump B, the voltage of two out of the 10 ion-exchange membrane electrolyzers drops by 3–5 volts immediately, resulting in a reduction in production volume of about 1 ton per shift. At present, it can only be said that reversing the pump causes a decrease in tank voltage and production. I really can’t figure out why reversing the pump will affect the power reversal tank Seeking guidance!
This situation should not occur; reversing the pump can affect the quality of the brine, which in turn affects the electrolyzer.
At the moment the pump was reversed, the tank voltage dropped； When switching back to the original pump, the tank voltage rises immediately; based on this, there is no issue with the quality of the brine.
Is there a significant change in the liquid level of the brine sump during pump reversal? Is there any change in the flow rate of brine entering the sump?
During pump reversal, the liquid level in the brine sump remained stable at 85%, and there was no change in the flow rate of brine entering the sump. I really can’t figure it out
There is a problem with the pump seal; cooling water entering the system has caused the salt content in the brine to decrease. Check whether there is any change in the alkali concentration after reversing the pump.
