The waste liquid cannot be discharged
Thread Content
Chlorine reacts with sodium cyanide in the adsorption tower; the sodium cyanide solution is circulated using a pump, while chlorine is introduced from the bottom. The waste liquid generated by the reaction cannot be discharged. I urgently need advice from experts on how to solve this problem
It shouldn’t happen; your tower is at slightly positive pressure, so how could there be no exhaust? Strictly speaking, what you have there is an absorption tower for chemical absorption, not adsorption.
The waste liquid discharge outlet is located 50 centimeters below the packing. During the current production process, the waste liquid does not flow out through the discharge outlet but rather comes out from the pH meter tube on the side. I would appreciate it if experts could help analyze the reason for this
There’s no blockage anywhere; when it’s removed, bubbles are present in the waste liquid. Could gas not be able to escape beneath the filler, thus creating a pressure difference?
Simply indicate the relative position of the PH port and the drain port, or take a photo
It shouldn’t be like this under normal circumstances. Check to see if something is blocked, and is the area where the equipment is located very cold?
