Reverse-circulation axial discharge type evaporation crystallizer?
Thread Content
What is an externally heated forced counter-current axial discharge type evaporation crystallizer? What are the advantages and disadvantages of reverse circulation and forward circulation?
An externally heated evaporator is what is commonly referred to as an external heat-type evaporator. In this type of evaporator, the heater is placed outside the evaporation chamber, forming two separate units that are connected to each other through pipes. As for the direction of material discharge, most evaporators use axial discharge. Forced circulation is a solution designed to address the problem of crystallization-induced blockages in the heat exchanger; it can operate in either the same direction as or opposite to the flow of the material. The effective volume of the counter-current evaporation chamber will decrease, and the strength of the evaporator will be reduced; generally, it is a forward current system
