摘要
溶质的存在可使溶液的蒸汽压较纯水的的低,从而使沸点升高。不同性质的溶液在不同的浓度范围内沸点上升数值是不同的,浓度越高沸点升高也越大。沸点升高会导致蒸发器的换热面积增大,在计算蒸发器换热面积时是不能忽略的。仅以RNJM03-6300型三效降膜式蒸发器为例加以阐述。
the existence of the solute can make the solution of low vapor pressure than pure water, so that the boiling point elevation. Different nature of the solution in different concentration with-in the scope of the boiling point rise in value is different, the greater the concentration, the higher the boiling point increases. Boiling point may lead to increase evaporator of the heat transfer area, when calculating the evaporator heat transfer area can’t be ignored. Triple effect only with RNJM03-6300 type falling film evaporator as an example.
