Seeking expert advice on heat dissipation issues in crystallization tanks
Thread Content
The jacket of the crystallization tank uses tap water for cooling, and then a chiller is used for further cooling. The initial temperature of the logistics material is 60 degrees, and it needs to be reduced to 15 degrees. How should it be designed reasonably? Is it more appropriate to use storage tanks or cooling towers for cooling?
Analyze each specific issue; batch operation or continuous operation? Is an external heat exchanger needed? Is there enough heat exchange surface? In the case of continuous crystallization, it is recommended to divide the process into stages; the first stage can be cooled with cold water, with the temperature being kept around 35 degrees, depending on the temperature of the water source. Apply frozen saline to the latter section. From the perspective of energy saving and improving yield, flash evaporation can also be considered, and the mother liquor from crystallization can serve as a cooling source. Consider it all together.
The temperature is not high; cooling is achieved through a cooling tower with circulation. Save water. Or use deep well water to cool down.
