- The advantages of its energy conservation and environment protection are firstly stated when an industrial heat pump technology is applied for evaporation process of waste solution. Based on a concentrate need of zinc sulfate, a process design of heat-pump evaporation system is done, and a heat-pump prototype combined with water lubrication during compression stage is developed. Then, as far as the prototype machine, its characteristics of evaporating and concentrating zinc-sulfate solution are tested and analyzed by an experiment way when the heat pump runs according to the designed process. The study results shows that its concentration factor of zinc sulfate could be more than 3.0 by heat-pump evaporation process. And its energy-efficiency ratio (EER) could not be less than 4.6 as far as heat-pump evaporation prototype.
