Problems with central circulation tube evaporator
Thread Content
The medium of the central circulation tube evaporator equipment is sodium chloride and barium chloride, so is the final solution obtained a concentrated high-concentration sodium chloride and barium chloride solution? Crystallization shouldn't be a product of a standard evaporator.
Thanks, big brother, please help me. Don’t bother to answer the question because it’s too simple?
Your question is not very clear and I don't know what problem you want to solve. If the material stays in the evaporator for a long time and the solution is oversaturated, then crystallization will occur. If the material stays in the evaporator for a short time and the material is not saturated, then there will be no crystallization.
There will be a crystallizer at the bottom of this central circulation tube, which will gradually turn into a crystal slurry. When the concentration is reached, the material can be discharged through the discharge pump, and through repeated concentration and thickening measures, and finally through solid-liquid separation by a centrifuge, the entire crystallization process is completed.
It is similar to such a central circulation tube evaporator. The medium is NaCl and BaCl2. Then it pays attention to whether it obtains highly concentrated sodium chloride and barium chloride solutions.
It depends on what your purpose is? You want a concentrated solution, which is an unsaturated solution without crystals, but you just need to control the amount of evaporation. If you need a crystal, what comes out is a certain crystal. You just need to continue evaporating the saturated solution. It seems that I didn’t read the chemical engineering principles textbook carefully!
