Heating Area: Determine the evaporator heating area is a reference material balance, heat balance, heat transfer calculation and post-process such as the use of form factors considered in making a decision. From the use of multi-effect evaporator to distinguish it can be divided into: ordinary multi-effect evaporation system, forced circulation multi-effect evaporator. Forced circulation evaporator is evaporated by the outer loop based on more than one additional external circulation pump. Generally speaking, the energy consumption with heat pump double-effect evaporation system with almost three-effect evaporation system, it can increase the flow of materials within the evaporator tube to improve heat transfer effect, increasing evaporation intensity. 3, the process of selection: when the downstream in the operation, the aftereffect of the evaporation chamber pressure lower than the previous effect with black liquor evaporator, low-power solution transport efficiency between the desired pump. In addition, as aftereffect evaporation temperature lower than the effect, so the front-efficient solution was flashed into the aftereffect will be part of the steam, so that less raw steam consumption. But downstream flow aftereffect of concentration, the lower the temperature, the viscosity will be higher, the heat transfer rate is small. When the reverse operation and downstream operations contrary, that effect before the temperature is high, the concentration is high, the aftereffect of low temperature, the lower the concentration of black liquor and evaporator manufacturers, the heat transfer rate of each effect is close to the model with black liquor evaporator , but the desired effect among Passing Pump power outlet with black liquor evaporator, steam consumption, too. Not suitable for handling heat-sensitive materials, also suitable as the temperature and concentration increased, medium corrosive materials enhanced. Here you can use the material according to the specific circumstances of advection and mixed flow.
