Distillation kettle level selection
Thread Content
The existing distillation vessel has a capacity of 2000 liters; it operates under negative pressure, with a distillation temperature of 70°C. The residual material is quite viscous at the end, and there is no mist inside the vessel during the distillation process； Current analysis: Double flanges cannot be used due to crystallization ； The float ball cannot be used; there is stirring inside it ； Ultrasonic waves cannot be used because of the negative pressure ； The radar cannot be used; the detection probe is too close to the tank wall ； Seeking advice from fellow sea lovers
Since there is no mist inside the tank during the distillation process, it is not necessary to install a level gauge; it can be checked directly. (Haha, do the opposite)
Thank you to those who replied; none of these methods work, and I hope everyone will continue to participate
It can be used with radar, E+H models, even on small 100L kettles
The method suggested upstairs is good. The problem is that there are approximately 7–8 process pipes on the boiler; should all of them be replaced with flexible connections? Additionally, due to continuous feeding, does the expert upstairs have any other good suggestions?
It seems there is a problem with my description; determining how to use a pivot point is a rather tricky issue, as crystals will form after distillation for a certain period of time. I would like to ask for further advice
Actually, the claim that the radar mentioned by the original poster doesn’t work is a bit absolute; it seems the poster hasn’t conducted any tests. I guess it’s actually possible to use radar for that
Reactor vessels are usually equipped with weighing functions; you can consider this aspect
For guided-wave radar level gauges, the rod-type version should work fine; as long as the tank wall is smooth and flat, with no additional instruments installed on it or any other obstacles, a distance of 50 mm is sufficient. We use this type of gauge regularly, and it works well even with viscous fluids – we have also used it for asphalt
