Description

technical field

[0001] The invention relates to the technical field of heat pump evaporators, in particular to a spray condensing device for an atmospheric pressure heat pump evaporator. Background technique

[0002] Heat pump evaporation refers to compressing the secondary steam evaporated by the evaporator with a compressor, increasing its pressure, making its saturation temperature exceed the boiling point of the solution, and then sending it back to the heating chamber of the evaporator as heating steam. This method is called heat pump evaporation. , the use of heat pump evaporation only needs to supply heating steam during the start-up stage of the evaporator. When the operation reaches a stable level, no heating steam is needed, and only the work required to increase the pressure of the secondary steam is provided, thus saving a lot of raw steam;

[0003] The condensing device of the existing atmospheric pressure heat pump evaporator uses water vapor to exchange heat t...
