Discussion on Leak Sealing Techniques for Dry Absorption Tower Tank Casing
Thread Content
In my opinion, in sulfuric acid production, especially when producing acid from smelting flue gas, if the lining of the dry absorption tower tanks is not properly installed during the initial construction of the plant, it has a serious impact on subsequent sulfuric acid production. If mortar is poured into the sleeves of the acid-leaking tower tanks during annual maintenance, the quality of this work cannot compare to that achieved at the time of the plant’s original construction; over time, the mortar in these sleeves will be washed away, leading to production interruptions. Let’s discuss what methods are being used to maintain the mortar in the sleeves of the dry absorption tower tanks during annual maintenance
Just go straight to Zhongshun Leak Repair – it’s been over two years now, and nothing seems to be wrong.
There are two scenarios in this case: 1. During the initial construction, special attention should be paid to this issue. The traditional method involves mixing KPI clay into a liquid state and pouring it in; after curing, the material shrinks by 30-50%, and due to air being trapped inside, some materials fail to cure properly, leading to leaks once the vehicle is in use. It causes a lot of headaches for property owners. 2. After the leakage occurred, many external welded iron boxes were used along with KPI putty, which prevented leakage in the short term; however, the internal corrosion was not resolved.
The best approach is to remove the sleeve entirely; after inspection, if sandiness or damage is found, replace it with a new sleeve. Clean the existing sealant at the installation site thoroughly, and it’s advisable to dry it out by baking it. Then reinstall the sleeve and carry out multiple filling processes, making sure that the material has a high solid content. Finally, apply glue several times to ensure no further leaks occur.
Remake the sleeve and plug it with KPI putty and asbestos rope.
