Forced circulation evaporator generally consists of heating chamber, evaporation chamber, circulation pump and so on. Relying on the circulation pump, the material liquid passes through the heat exchanger tube with the flow rate of 1.5~3.5m/, the material liquid in the heating chamber is only heated and not evaporated, so it inhibits the salt precipitation and thus avoids the scaling, and the faster flow rate can slow down the scaling, and it has a high heat transfer coefficient. After heating the material into the evaporation chamber, due to the pressure reduction and flash evaporation, the material may appear salt precipitation, but because there is no heat exchange surface in the evaporation chamber, so there is no scaling problem.
Hallmark
l forced circulation evaporator is suitable for easy to scale or salt precipitation material concentration is also often used as FC crystallizer. The disadvantage is that the configuration of large flow circulation, high power consumption.
Characteristics of system
- Lowest energy consumption and operation cost, electricity consumption of one ton water's evaporation is 2.2kw/℃.
- Temperature difference is small, heating is gentle, the loss of product is less.
- Compact structure and lower building cost; plant area is 50% less than that of traditional evaporator.
- Surrounding is friendly, no gas and no steam.
- Good adaptability in low loading condition, flexibility of operation is good and has a longer service life.
- Consumption of circular water is low and energy saving is obvious.
- No fresh steam is needed.
- Evaporation can be carried out under 40℃ and equipment need not to be frozen, specially suitable for thermal activity products.
