Forced circulation evaporator

Forced circulation evaporator: Product overview and features: Forced circulation evaporator relies on an external force circulation pump to circulate the liquid to increase the flow rate of the solution. Its heating chamber has two structures: horizontal and vertical, and the liquid circulation speed is adjusted by a pump. According to the different positions of the inlet and outlet of the circulating material liquid in the separation chamber, it can be divided into a forward circulation forced evaporator and a reverse circulation forced evaporator. The circulation flow rate of liquid in the heating tube is usually within the range of .~3.0 meters/second (when there are many crystal grains in the suspension, the hardness of the pipe used is low, and the viscosity of the liquid is large, a low value is selected). The heating tube can be vertical Single-way, vertical two-way, horizontal one-way, horizontal two-way. The latter two have smaller overall equipment height but the pipes are difficult to clean and easy to wear the pipe wall. The advantages of this type of evaporator are: large heat transfer coefficient, resistance to salting out, anti-scaling, strong adaptability, and easy cleaning. Disadvantages: long solution residence time, slightly higher construction and maintenance costs, and large power consumption.
Working principle: The circulation of solution within the equipment mainly relies on the forced flow generated by external power. The circulation speed can generally reach ..m/s. The heat transfer efficiency and production capacity are large. The raw material liquid is driven from bottom to top by the circulation pump and flows upward along the tube of the heating chamber. The mixture of steam and liquid foam separates after entering the evaporation chamber. The steam is discharged from the upper part, and the fluid is blocked and falls. It is sucked into the circulation pump through the conical bottom and then enters the heating tube to continue circulation.
