The triple effect forced circulation evaporator is suitable for use in working conditions with high incoming concentration, and has the characteristics of easy operation, strong anti scarring ability, and wide applicability. Each evaporator is equipped with a forced circulation pump to ensure the flow rate inside the heat exchanger tubes.
The triple effect forced circulation evaporator utilizes gas three times, and the steam consumption ratio can be controlled at around 0.4. Forced circulation evaporator is an efficient circulating evaporation device. The circulation of the solution inside the equipment mainly relies on the forced flow generated by external power, and the circulation speed can generally reach 1.5-5 meters per second. When the circulating liquid flows through the heat exchanger and is heated, it partially evaporates when the pressure drops in the separator, that is, the liquid is cooled to the boiling point temperature at the corresponding pressure. Due to the circulation pump, the material's recirculation speed can be precisely adjusted, and the evaporation rate is set within a certain range. In crystallization applications, crystals can be separated from the circulating slurry by adjusting the circulation flow rate and using special separator designs. The advantage of a forced circulation evaporator is that it has a high heat transfer coefficient and is suitable for processing materials with high viscosity, easy scaling, easy crystallization, or solutions with high concentration. Our company has designed the optimal parameters for the evaporation of secondary steam from the liquid surface of the medium in the separation chamber, and determined the appropriate aspect ratio to ensure that the circulating solution enters the separation chamber and passes through the feed baffle, conical separator, bottom racemizer, top high-efficiency demister, etc., while maintaining the recirculation state internally.
The triple effect forced circulation evaporator is widely used in high salt wastewater, pesticide wastewater, chemical wastewater, etc.
