The common feature of a riser evaporator is that the refrigerant evaporates inside the tubes, and the entire evaporator tube group is immersed in a box (or pool, tank) filled with refrigerant. In order to ensure that the refrigerant circulates at a certain speed inside the box, longitudinal partitions are welded inside the box and a spiral stirrer is installed. The flow rate of the refrigerant is generally 0.3-0.7m/s.

　　evaporatorIt is a device that concentrates or precipitates grains from a solution by heating. The evaporator is mainly composed of two parts: the heating chamber and the evaporation chamber. The heating chamber is the part where steam is used to heat and boil a solution. The evaporation chamber, also known as the separation chamber, is the part that separates gas and liquid. The steam generated by boiling in the heating chamber (or boiling chamber) carries a large amount of liquid foam, which can be separated from the steam in the larger separation chamber due to its own condensation or the action of the foam catcher inside the chamber. Steam is often drawn to the condenser by a vacuum pump for condensation, and the condensate is discharged from the bottom of the condenser.
