Function of valve 21,39

For Asahi Kasei electrolyzers, once the liquid has been poured in, the circulation process begins; it is necessary to open valves No. 21 and No. 39 in order to release gas. Could someone please explain this in detail? This post was last edited by Captain Yang on 2008-4-29 at 08:08. ] # ， ， &
Personally, I think it serves to release the gas from the anode inlet main pipe. This allows the gas from the anode to be discharged through the anode outlet pipeline
I believe that after the electrolyte is poured into the cell, a galvanic cell is formed and a chemical reaction takes place; opening the release valve is intended to discharge this gas
It seems to be intended to facilitate the removal of gases like carbon dioxide, I guess:loveliness: Hehe, please forgive me if I’m wrong! Are all of them using Asahi Kasei electrolyzers? :handshake Then, is there anyone who knows exactly what the valve numbered 22 is used for? Could you let me know? Thank you :)
Valve 22# is used for cleaning and draining after the cathode inlet; valves 21# and 39# serve to prevent corrosion of the titanium tubes at the cathode outlet.
Valves 22# and valves 21# and 39# serve the same purpose: they expel the gas from the pipeline during the charging of the electrolyte
Agree with what was said above: when charging the electrolyte, the gas in the pipes should be released to ensure a uniform flow into the cell compartments, so that no dead zones occur.
It doesn’t seem right; it’s not just an exhaust issue, because the 21.39 value is also active during normal driving. So why is that?
21# and 39# are opened for exhaust and closed to prevent backflow. . It should be like this; our factory uses Kyocera’s tanks. :victory: :victory:
21, 39: It should be turned on while driving; its purpose is to remove CO2 from the brine into the anode gas phase, preventing this gas from entering the electrolytic cell, thereby reducing the cell voltage and minimizing bubble formation!
Same as what was said above; it should be turned on while driving, mainly to allow the excess alkali in the brine to react with the hydrochloric acid added at the anode to produce CO2, which is then released into the gas phase at the anode. This prevents such gases from entering the electrolytic cell, thereby reducing the cell voltage and minimizing bubble formation!
Our factory uses tanks manufactured by Beihua Machine; we hired the engineering technicians from Beihua Machine to operate them. When filling the tanks, they had valves 21, 22, and 39 opened, and these valves were closed after venting.
It is opened during liquid filling at 21.39 to remove gas from the pipes, and it is closed after filling to prevent backflow (this is stated in the operating procedures, but it’s not clear when backflow might occur). If acid is added to the electrolytic cell, it also needs to be opened in order to remove the CO2 generated by the addition of acid; the addition of acid can be confirmed by observing the bubbling.
