[Help] Stirring and coil design for concentration crystallization tanks
Thread Content
Seeking experts in the design of stirring systems and coil arrangements for concentration crystallization reactors; add me on QQ at 772834364
The stirring mechanism in the crystallization tank is designed as a frame-type stirrer; the rotation speed of the reaction tank should generally not be too high, with 20 revolutions per minute being an optimal value. The design of the coiled tubes must take into account the heat exchange requirements. It depends on the size of the crystallization tank: if the tank is not large, 1.5-inch or 2-inch tubes can be used. If a better crystal structure is desired and overcooling should be avoided, then smaller tubes should be used. Specifically, process considerations need to be taken into account. This is not considered from a technical equipment perspective.
The diameter of the crystallization tank is too large, resulting in poor fluidity of the solution; I want to change the stirring mechanism and see if it’s possible to move the double-layer coil one layer closer to the center in order to accelerate heat transfer and evaporation
