Is there anyone expert in defoamers? I’m seeking advice and help
Thread Content
The demister in our factory has a baffle-like structure, and it provides excellent demisting performance. However, a major problem is that scaling occurs quite severely after use for some time, which significantly hinders the passage of secondary steam. We have to remove it each time to carry out manual descaling, which is very troublesome. Could any experts give us some advice? Our factory uses gypsum-type brine (salt brine)
That is, the demister is not up to standard and does not meet your requirements for filtering media. It is recommended to use Lützholz filtration products
Our company is the general agent for Munters Process Industries in Germany. I consulted with our technical experts, and they said that this situation is inevitable in salt production; typically, nozzles are installed as part of the design. The refined salt plants in Shandong are using it quite well at the moment; it seems that this wasn’t taken into account during the initial design here, as no nozzles were installed
Hello, our factory’s demister is equipped with nozzles that clean it once every hour or so, but the effect isn’t very good. Could you please take a look at what information we need to provide and help me analyze the reasons? I would be extremely grateful. Also, are demisters with baffle plates not suitable for gypsum-type brine?
If possible, we can consider replacing it

For the demisters used in the evaporation crystallizers of vacuum salt production enterprises, high-efficiency vaned demister and mist separator systems represent an excellent choice. Pure baffle-type demisters offer relatively poorer performance, but they are still far superior to mesh-type and filter element-type demisters, which tend to clog easily. The brine droplets carried by the secondary steam tend to crystallize and adhere to the internal components. The internal structure of the demister requires design and selection by specialized companies in dynamic separation technology, and professional design and layout of the washing spray system are also very important. Otherwise, the crystals will adhere to the internal components and continue to grow, blocking the flow channels; even steam purging is unlikely to be effective in a short time, thereby having a significant negative impact on the normal production operations of the enterprise.
