The forced circulation evaporator circulates the liquid at a certain speed (usually within the range of 1.5-3.5m/s) through a pump or other power equipment. This high-speed circulating flow ensures that the liquid is thoroughly stirred and mixed inside the evaporator. Compared with natural circulation, its circulation speed can reach 3-10 times that of natural circulation type, which improves the processing efficiency of the equipment.

Heating and evaporation process: After the solution is heated in the heating tube, it enters the separator. Due to the decrease in pressure, some of the solvent evaporates into steam and is discharged from the upper part. The concentrated solution is then sucked back in by the circulation pump through the conical bottom and enters the heating tube again for circulation. During this process, the raw material liquid is pumped from bottom to top by a circulation pump, flowing upward along the inner tube of the heating chamber, continuously receiving heat and undergoing phase change separation.

Avoiding scaling and crystallization: The high flow rate design can effectively flush the pipe wall, reduce the risk of scaling, and is particularly suitable for handling materials with scaling and crystallization properties. At the same time, fast circulation also helps prevent solid substances from depositing on the heating surface, thereby maintaining the stable operation of the equipment.

Advantages of forced circulation evaporator:

1. High heat transfer coefficient and high evaporation intensity: The forced circulation mechanism makes the flow state of the solution in the heating tube more ideal, enhances the heat transfer effect, and improves the evaporation efficiency. This is particularly important for applications that require a large amount of evaporated water, which can significantly shorten processing time and improve production efficiency.

2. Strong resistance to salt precipitation and scaling: As mentioned earlier, high flow rate can effectively reduce the possibility of salt analysis and dirt formation, even in the face of high concentration or solutions containing many impurities, it can maintain good working performance. This reduces the frequency and cost of equipment maintenance.

3. Strong adaptability: high tolerance for fluctuations in water quality and quantity, suitable for the treatment of unstable working conditions such as industrial wastewater. Both high viscosity and suspended solids containing wastewater can be effectively treated. In addition, it is also suitable for various types of materials, including thermosensitive, high concentration, high viscosity, and materials containing insoluble solids.

4. Flexible operation: Through innovative design of the separator and accurate regulation of the circulation speed, it can operate flexibly within the range of 0-100 evaporation rates to meet the needs of different production processes. At the same time, highly automated control systems make operations easier and reduce the impact of human factors on operational performance.

5. Good concentration effect: This equipment can achieve a high concentration ratio, and the specific gravity of the concentrated product can reach 1.4-1.5, which helps to obtain high-quality products.
