Control method for the level of a stirred evaporator
Thread Content
We are facing a problem in production: the enamel reactors equipped with agitators often become full, and it’s difficult to control the temperature. Since sealing is required, conventional level detection methods cannot be used. I would like to ask everyone what methods you use to monitor and control the level and temperature in such situations. What are some good ways?
How do you feed materials into your enamel reaction vessels? Here, due to issues with the process formulation, we can only feed materials manually at the moment. Let’s exchange ideas on advanced technologies.
Radar level gauges and capillary level sensors can both be considered for measuring slurry levels
A single-flange level gauge will suffice
The glass-lined reactor has an enamel lining inside, so it seems that installing a flanged level gauge isn’t very suitable.
On our end, time control is calculated based on the pump’s flow rate and the actual volume of the reaction tank; this is because the difficulty in acquiring liquid level signals has prevented automation from being achieved
Time can be used to control the amount of feed. For example, feeding the reaction vessel with a pump allows for timing adjustments based on the pump’s flow rate. I don’t know if you use steam or electric heating over there. Electric heating is easy to control, as temperature adjustment can be achieved by using the thermometer in the control cabinet. Steam is also easy to deal with
