TEB EVAPORATOR is a kind of natural circulation evaporator. Heating steam enters between the tubes, and the heated solution circulates along the tubes of the heating chamber. TEB EVAPORATOR mainly includes central circulation tube evaporator, spiral tube evaporator, coil evaporator, etc.
With the needs and development of industry. The structure of the evaporator has also been gradually improved. For example, the jacket heating type was first replaced by the horizontal tube heating type, and then improved to the vertical tube heating type, and the latter continued to be improved in the widespread use. In order to avoid the influence of the static pressure of the solution, a liquid film evaporator was created. In order to improve the production intensity, an evaporator outside the heating chamber and a forced circulation evaporator were created. In addition. Save the method of heating steam. In addition to using the secondary vapor as a multi-effect evaporation, it can also be used in the original evaporator again by the secondary adiabatic compression to increase its temperature and be used as a heating vapor. The evaporator operated in this way is called a heat pump evaporation. Device. These improvements and creations are based on research on the basic principles of evaporation and many factors related to its production intensity.
The characteristics of TEB EVAPORATOR of various structures are as follows:
1. The shape and position of the heating surface—jacket, serpentine tube, straight tube, heating chamber inside or outside;
2. The placement method of the evaporator itself-horizontal, vertical, inclined;
3. The circulation method of the solution-natural circulation, forced circulation.
If you press the operation method. TEB EVAPORATOR can also be divided into batch type and continuous type. But no matter which type of TEB EVAPORATOR, it is composed of two parts: heating chamber and separation chamber. The heating chamber is also called the boiling chamber, which is the part where the material is boiled by heating with the saturated steam partition. It is actually a kind of heater, and the separation chamber is also called the evaporation chamber. After the solution is heated and boiled and vaporized in the heating chamber, the secondary vapor produced contains a large number of liquid droplets. The sudden increase in evaporation space of the evaporation chamber is used to make the liquid droplets condense and settle and separate from the vapor.
