Reasons for the gradual decline in the liquid level in the circulation tank of the waste gas absorption tower
Thread Content
The liquid level in the circulation tank (20 cubic meters) of the waste gas absorption tower of the chlorine treatment unit is gradually dropping, by 2% per day. There are no leaks at the site; could it be that the negative pressure created by the exhaust fan is causing the alkaline solution to be drawn away?

I came across a similar case before: the gas after washing is pressurized by a compressor, and if the washing pressure is not properly controlled, the alkaline solution can be drawn into the buffer tank located in front of the machine by the compressor. For your reference
Under negative pressure, the water in the alkaline solution evaporates, gradually concentrating it
The temperature control is good, right? Otherwise, they wouldn’t have fallen in love with Ang so quickly
Currently, the unit is in shutdown mode; all exhaust gases from the system have been replaced. All equipment is stopped, with only the exhaust gas treatment unit operating.
The gas dissolved in the liquid gradually evaporates, and it is estimated that it will remain constant once a certain liquid level is reached!
It keeps raining every day; I’ve been observing this for half a month now.

Or the valve that leads the circulation pump to the finished sodium hypochlorite is not sealed properly, allowing fluid to reach the tank containing the finished sodium hypochlorite.
An experiment was conducted: the alkali solution circulation pump was operating normally, and once the exhaust fan was turned off, the liquid level stopped dropping.
The exhaust gas containing the inert components that is absorbed essentially has saturated moisture, resulting in a loss of water in the absorption solution.
It was found that there was a large amount of alkaline liquid accumulated at the induced draft fan; several buckets’ worth of it was removed, but there is a baffle mist eliminator before the exhaust tower’s outlet – so why isn’t it effective?
