Moisture

Why is the moisture content at the outlet of the fans in my factory as high as 0.3–0.69?
To resolve such issues, it is necessary to provide some parameters for others to refer to. Local relative humidity, the concentration of the drying acid used, the amount of acid in the drying tower, etc. – in other words, these factors can be adjusted to monitor the moisture content.
It is also related to the amount of dry acid sprayed, as well as the flow of air inside the drying tower
It could also be due to whether the acid distribution in the acid distribution tubes is even, whether there are problems with the degasser, or issues with the tubes used for sample preparation and sampling
Reply 2# melao: Concentration of the drying acid is 93.5%–94%; the amount of acid used in spraying is 320. The ceramic rings were removed during maintenance work

First, it’s necessary to determine what kind of equipment your factory has in order to analyze the cause
Is it acid produced from minerals or from sulfones? If it’s acid produced from sulfones, there are also pre-column and post-column processes to consider, and then experts can help you analyze it, haha
In my opinion, if it’s a fan located behind the tower, check whether there are any leaks in the negative pressure area of the fan.
The moisture content at the fan outlet is not up to standard; it does not reach 0.1 g/cubic meter... It should be the process after the tower, right? ? In my opinion, in addition to the acid temperature and amount at the top of the drying tower, as well as whether the acid distribution mechanism is even, it is also necessary to check for any leaks in the pipes and valves leading from the drying tower to the fan (to prevent wet air from entering the system) ； And check whether there is air leakage at the seal of the fan shaft seal collar. (Haha... it’s just my personal opinion; I hope we can learn together*:lol)
Too high a moisture content means that both environmental standards and equipment requirements are not met. The equipment is likely leaking severely.
