A forced circulation evaporator is a device that uses a pump to transport liquid, forcing it to flow through a heating chamber at a high speed, separating the driving force of circulation from the functions of heat transfer, vaporization, and gas-liquid separation. Therefore, the forced circulation evaporator has strong adaptability. It has the advantages of high evaporation intensity, low scaling, and high operational flexibility.
working principle
The forced circulation evaporator circulation pump usually uses an axial flow pump, which has a simple structure. High flow rate and low head. Very suitable for high flow rate and low head forced circulation evaporation systems. At the same time, the axial flow pump has a lower rotational speed, which reduces the frequency of maintenance.
Performance characteristics
The entrainment of secondary gas in forced circulation evaporators can easily cause condensed water to contain materials, so we usually use cyclone type separation chambers with baffles and labyrinth demisters at the top to effectively reduce or avoid gas-liquid entrainment and ensure the quality of condensed water. We have applied it multiple times in engineering and achieved good results.
Adapt to materials
The forced circulation evaporator can be widely used to handle solutions with viscosity, precipitation crystallization, easy scaling, or high concentration. Its applicability under vacuum conditions is outstanding. The forced circulation evaporator designed and produced by our company is widely used in the evaporation and crystallization operations of materials such as sodium chloride, ammonium sulfate, magnesium sulfate, zinc sulfate, sodium sulfate, sodium sulfite, sodium gluconate, cobalt chloride, gulonic acid, and alkali sulfide.
