Diagram of double-effect evaporator equipment, process flow diagram, and requests for assistance with issues
Thread Content
Dear experts: The factory has a double-effect evaporator. If any of you can provide the equipment diagram and process flow diagram, I would be very grateful. The main issue at present is that the original design called for a processing capacity of 2 tons, but currently it’s less than 1 ton. I’m not sure what the reason is; I would appreciate any guidance from everyone. Thank you!
What kind of device is it? What kind of process? Which unit?
Without any specific conditions, a random answer is given; the processing capacity is less than half of the desired level. Possible reasons include a small actual heat exchange area, changes in the properties of the material (increase in boiling point), or failure to meet certain conditions (such as insufficient vacuum, inadequate steam pressure, or insufficient material circulation rate).
This is a simple A; take a look at what your process looks like and I’ll help analyze it for you
It’s very likely that scaling has occurred. It is recommended to add chemicals
It’s recommended to describe the problem in more detail; that makes it easier to respond:D

It is necessary to figure out whether there is internal or external circulation in the heating chamber, whether it is forced circulation or natural circulation, whether it is in co-current or counter-current mode, and how the crystals are extracted. The reasons for insufficient production capacity are: 1. The evaporation driving force is not always sufficient. 2. Crystallization in the heating chamber requires efficient washing, forced washing – it is not a routine ordinary operation. 3. Leakage in the heating chamber. 4. If there is a vacuum, does the degree of vacuum decrease?
There is always a difference between design and reality
