Automated design for the steam-to-circulating water switching process in reaction vessels
Thread Content
In fine chemical manufacturing, the steam in the reactor jacket and the circulating water system need to be switched back and forth intermittently. Previously, manual operation was used to determine whether the water had been completely drained; implementing automated control proved to be complicated. Could using compressed air to actuate the valves for delaying their opening and closing be a viable solution?
Give it a push; I need information on this too
Just use the coil inside the outer jacket, right?
Using compressed air works, but the pressure needs to be high enough; it’s better to use a semi-tube jacket. However, the steam trap must be one that is capable of releasing air, such as a thermodynamic steam trap
This one of yours will also work, but what about enamel reaction kettles?
At that time, my design involved using heat transfer oil, with switching between cold and hot oil
To determine whether the water has been completely drained, the temperature at the condensate outlet can be used as a indicator; a temperature above 100 indicates that the water has been drained. Steam enters the jacket from the top and exits from the bottom. If water quality requirements exist, the water can be discharged into the cooling water system.
Who has any drawings related to this that they can share with everyone? Thank you!
