What are the inspection items for the bubble dryer?

It mainly involves checking whether the tower plates are deformed or tilted； Whether the blister is damaged or detached. These are generally checked during major parking overhauls; it is also possible to install viewing glasses on each tray of the bubble column to enable observation during normal operation.
Generally, it involves checking the trays and cups as well as cleaning up the acidic sludge!
Reply to 2# wqhhdiaodu: The control of moisture content in chlorine at our company has never been very good. The manufacturer suspects that it is due to the bubble column; will checking those items you mentioned be sufficient?
Reply to 4# Ziyi: What I’m referring to are the items that should be checked in a bubble column. There are many reasons for excessive water content in chlorine, and the main cause is improper operation; it’s not advisable to blame the equipment alone.
Reply to 5# wqhhdiaodu: All possible causes were checked, and it was only after that that the manager decided to inspect the bubble column. Does the bubble column have a significant impact on the water content in chlorine?
The bubble column is the last and most important stage in the drying process; it has a significant impact on chlorine content. Our factory has encountered this problem before – the chlorine content remained very high, which led to issues with the installation dimensions of the bubble columns.
Reply to 6# Ziyi: The bubble tower relies on a chlorine distributor at the bottom of the tower to ensure that chlorine spreads evenly across the 5 layers of trays, allowing it to come into full contact with sulfuric acid and thereby remove moisture Open the bubble column and check the items I mentioned above; if there are no problems and the design of the bubble column is also fine, you can analyze it based on the following points: 1. Whether there is liquid flooding during normal operation, 2. Whether there is any leakage (that is, whether the sulfuric acid level on the tray can be maintained), 3. What is the acid concentration? 4. Chlorine temperature at the tower exit? It is recommended to add a sight glass for daily operation! It’s mainly about operations: lol
Main: Check whether the tower plates are deformed, cracked, or tilted； Whether there is any damage or detachment of the blister. Is there any accumulated acid sludge on each layer of the bubble tray?
It is recommended that bubble dryers not be chosen for future designs; the bubble structure itself isn’t a problem, but the issue lies in the fact that the temperature of sulfuric acid and chlorine gas inside the tower cannot be removed in a timely manner, which affects the drying efficiency. What do you think?
The bubble column has a significant impact on chlorine moisture content; the chlorine moisture level here has always been high due to large cracks between the tray plates and the tower walls
