BÖWE Overboil protection for distillation
BÖWE Overboil protection for distillation
PROBLEM:
Ever since dry cleaning machines have been in existence, the problem of distillation boil over (also: black-over) has been known in the industry. Due to the addition of low temperature boilers such as water, high humidity, dosing additives and substances removed from the garments during the dry cleaning process, the boiling behaviour of the solvents and the low boiler mixture can change. This results in froth and a black-over of the distillation. This problem is particularly known in the case of alternative solvents, which have been used more and more in the last few years.
SOLUTION:
BÖWE decided to tackle this situation and developed a new photoelectric sensor. During the distillation process, the surface of the liquid in the distillation is monitored. If there is increased bubble formation, the sensor detects this situation and automatically breaks the vacuum for a short time. This leads to an increase in the boiling point and a collapse of the foam head. Black-over and dirt transfer are thus prevented.
The Overboil protection for distillation is available as an option for the BÖWE Multisolvent® dry cleaning machines
ADVANTAGES:
- No need for annoying and expensive cleaning of the water separators and clean tanks
- Therefore no odor formation
- Energy-intensive distillation of contaminated tank contents is no longer necessary which saves a lot of energy, time and cooling water.
