Liquid level control method for thin-film evaporators
Thread Content
The new project now has a scraper-type thin-film evaporator; it doesn’t have a liquid level control system, nor is there any control for the heating with heat transfer oil? Due to the lack of level control measures, I cannot determine whether the scraper has dried out or been submerged! I wonder how people managed it in the past? My original project involved intermittent operation of a thin-film evaporator, with a buffer tank connected to its lower part. I wonder if anyone has a better method
For the frequency conversion interlock of shielded pumps, we have been using scraper-type thin-film evaporators.
What process parameters are interlocked for shielded pumps? How do you determine that the liquid level is gone? By using the pump’s current? Or what?
Our film debenzing process is continuous; controlling the frequency conversion is sufficient
How to control the liquid level! How do you adjust the frequency conversion of the pump? There must be some basis for it; it’s not possible to adjust it arbitrarily. Or perhaps the frequency conversion of the pump is linked to certain parameters for interlock purposes. How do you determine whether the liquid has been completely evaporated?
The shielded pump is interlocked with the liquid level, and the temperature of the thin-film evaporator is adjusted according to the product specifications.
