How to measure the mist entrainment amount above the tray
Thread Content
To measure the amount of mist entrained above a tray, I found that the weighing method is used for this purpose; it involves installing a demisting plate at a certain height above that tray, and then directing the collected liquid out of the tower. How exactly is it supposed to be done? I can’t figure out how to collect the liquid gathered on the defogging plate and then drain it ? ?
The liquid collected on the defogging plates is gathered together and then drained away
Add a liquid collection extractor below the demister.
The accuracy and reliability of the method involving installing a demisting plate above the tray to collect the amount of mist entrained are questionable. Firstly, what size of liquid droplets can the defogging plate capture entirely? Secondly, above the tray, the airflow velocity varies at different positions; moreover, the size and quantity of liquid droplets carried by the airflow also differ in different locations. Is it necessary to install demister plates across the entire cross-section of the tower? Could you post a more detailed measurement plan so that others can help analyze its reliability and accuracy?
