The basic concepts and characteristics
of the principle of 1. chemical evaporation The principle of
chemical evaporation refers to the physical process of heating a liquid to its boiling point and making it evaporate into a gas state. In terms of mechanism, evaporation is a process of material transfer from liquid to gas, which needs to overcome intermolecular gravity and has endothermic effect. Therefore, temperature and evaporation rate are positively correlated. Chemical principle evaporation has the following characteristics:

1. at low temperature, less material quality loss;

2. can process the solution containing sensitive substances to avoid high temperature damage;

3. can neutralize acid, alkali and other chemical substances to eliminate the impact on product properties;

4. simple operation, high safety and strong reliability.

2. chemical principle of evaporation equipment and process application

1. Evaporator

evaporator is one of the core equipment of chemical evaporation principle, generally in accordance with the heating mode can be divided into steam heating and electric heating type two. According to the structure, it can be divided into external circulation type and internal circulation type, which is suitable for various chemical production industries.

2. Chemical principle of evaporation process application

chemical principle of evaporation process is widely used, mainly including the following aspects:

(1) concentrated

dilute solution evaporation concentration, so as to improve its concentration, so that its quality in line with production requirements. Through the chemical principle of evaporation, the concentration efficiency can be greatly improved, and it is suitable for a variety of materials.

(2) Condensation recovery

In the chemical production process, many useful substances are difficult to recycle due to high temperature. Using the equipment combination of the evaporator condenser of the chemical principle, the useful substances evaporated can be quickly condensed and recovered to achieve the maximum utilization of resources.

(3) Boiling evaporation

For volatile substances such as fruit juice and cosmetics, if traditional heating equipment is used for processing, a large amount of waste will occur. Using chemical principle evaporation for boiling evaporation can not only avoid this waste, but also improve the quality of products.

3. Conclusion

Through the explanation of this article, readers have learned some basic knowledge and characteristics of chemical evaporation, as well as the structure and process application of the evaporator. Chemical principle Evaporation is a very important chemical processing technology, which is widely used in various industries, such as fine chemicals, food, medicine, cosmetics, etc., to improve production efficiency, improve product quality, save energy and resources are of great significance.
