Circulating evaporator

operation

According to the principle of the siphon pump or climbing film, to stay concentrated liquid at the bottom of the heating tube into the evaporator, and then the class to the top, because the outside of the tube heating, evaporation liquid membrane began to boil and part of the tube wall. The upward movement of the steam produced, as a result, liquid is transferred to the top heater. Liquid and steam generated in the evaporator in the downstream of the separator, liquid through a circular tube back to the evaporator, a stable and uniform cycle is formed. Heating chamber and the bigger the temperature difference between the boiling chamber, the more evaporation, liquid circulation faster, also affected by the heat transfer effect is better. In order to achieve high concentration in the end, and boiling room space compared to system, if the cycle of the evaporator boiling room is divided into several independent small rooms, each room equipped with its own liquid ring system, heating surface area will be significantly reduced. Ultimately achieve the concentration in the last room only. In the other room, because the boiling point and low viscosity of liquid, can greatly enhance heat transfer effect

The characteristics of

Quick start, large capacity - due to the heating tube is relatively thin, short (1-3 m), evaporator liquid capacity is very low.

Range of application

1: in need of large evaporation rate of the cases, not suitable for high temperature sensitive products evaporation

2: suitable for extremely easy crusting of the products and performance in high speed flow can reduce the viscosity of non-newtonian fluid evaporation

Top 3: have separated boiling chamber and separator high circulation evaporator can be used as a concentrator, design of vertical tube heat exchanger, heat exchange tube short, separator is installed on top of a heat exchanger in the side
