Evaporator is a device that can realize heat transfer and material transfer, and its main functions are as follows:
1. Heat transfer: the heat of the high temperature medium is transferred to the low temperature medium, so that the material transfer occurs.
(2) Evaporation: by increasing the temperature of the liquid to make it vaporize, thereby transforming the liquid into a gaseous state.
3. Concentration: The impure molecules of the liquid substance are discharged with the vapor body, so that the liquid substance is concentrated.
Different types of evaporators have different characteristics, mainly as follows:
1. Good heat transfer effect: the evaporator has high heat transfer coefficient and obvious heat transfer effect.
2. Small footprint: the compact structure is used to effectively reduce the volume size.
3. Low maintenance cost: the internal structure of the evaporator is simple, easy to clean and maintain.
4. Energy conservation: Through evaporation, energy conversion can be achieved, thereby saving energy consumption.
Because the evaporator has many advantages such as good heat transfer effect and low maintenance cost, it has been widely used in different industries:
1. Air conditioning and refrigeration: liquid chillers, refrigerators, etc.
2. Chemical industry: multi-effect evaporator, process still, etc.
3. Food processing field: dynamic scraper evaporator, vacuum air dryer, etc.
In short, the evaporator is a very important heat exchanger, which can play different roles in different fields. Reasonable selection of evaporator types and application methods can improve production efficiency, save energy costs and strengthen production safety.
