High-level anode and cathode tanks
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 20:09. Why is the height of the anode sump much greater than that of the cathode sump? hcbbs hcbbs
Because the anode chamber of the electrolyzer is larger than the cathode chamber, about 3:2
First: the anode high-level tank is at atmospheric pressure, while the cathode high-level tank is at 44 KPA. Second: it comes down to considerations related to specific gravity. Third: it relates to the circulation pumps for the anode and cathode. As for other reasons, you’ll need to look into those further.........
By specific gravity, do you mean the density of saltwater and alkalis? That determines the height of the tank, not its size, right?
Is the first point you mentioned accurate? If that’s the case, it does solve the question I posted about the gas phase pressure difference; I had been confused about why it was the way it was, and now I understand
Yeah, on a whim, I decided to address these two questions together; in the past they were always tested together. Sorry about that.........:L:L
It should be correct; you’ll need to look up the details on your own......... This is all the help I can give you.......
Personally, I think it has a lot to do with the operational requirements. First, adjust the tank temperature on the cathode side. Secondly, the anode sump is required to provide fresh brine for a certain period of time to ensure the normal operation of the electrolyzer when secondary brine supply is unavailable. Third, the volume of the cathode chamber in the Beihua Machinery system is smaller than that of the anode chamber. In short, this design is intended to meet the requirements of the manufacturing process
Ah, the alkali surge tank is connected to the hydrogen gas main pipe, while the brine surge tank isn’t connected to any gas main pipe, so it remains at atmospheric pressure. But on our end it’s 20 for chlorine and 24 for hydrogen; the alkali sump should be at 24 kPa
It is mainly the displacement of chlorine gas inside the pole chamber after a power failure during an emergency stop. .
I agree with your view. The intermediate brine tank is also provided to ensure there is sufficient brine available to replace the anode chamber in the event of an emergency shutdown.
