The heat pump part consists of a heat pump compressor, a heat pump condensation system (the heat pump working fluid side in the tube), a throttle valve and a heat pump evaporation system (the heat pump working fluid side in the tube) to form a closed passage, in which the heat pump working fluid is filled and circulates. The atomization system module of the material-liquid evaporation and concentration chamber is composed of the heat pump condensation system (material-liquid side outside the tube), fan, and heat pump evaporation system (gas medium side outside the tube) in the material-liquid volume system, in which the gas-filled medium circulates. The heat pump working medium in the heat pump and the gas medium in the material liquid evaporation and concentration chamber work in coordination according to different processes. The heat pump working fluid is boosted and heated by the compressor and then enters the heat pump condensation system (the heat pump condensation system is located in the material-liquid volume system in the evaporation concentration chamber). It releases heat in the tubes of the heat pump condensation system and condenses into liquid, which enters the throttle valve. After throttling, it becomes a low-pressure and low-temperature heat pump working fluid liquid (accompanied by a small amount of flash gas), and enters the heat pump evaporation system. In the heat pump evaporation system tube, the heat pump working fluid evaporates and absorbs heat and turns into gas, and then enters the compressor to start the next cycle. In the material liquid evaporation and concentration chamber, the gas medium coming out of the heat pump evaporation system (the outer fin side of the tube) has a low temperature and contains very little water vapor. Driven by the fan, the material liquid is atomized and forced to pass through the evaporation chamber and the condensation chamber. In the process of passing through the material liquid, the gas medium and the material The liquid fully transfers heat and mass. When it reaches the top of the material-liquid volume system, the gas medium turns into a hot and humid gas with a higher temperature and a water vapor content that is basically saturated. Under the action of the fan, it is sucked away from the material-liquid volume system and enters the heat pump evaporation system (gas medium side). In the heat pump evaporation system, the gas medium and the water vapor contained in it are cooled by the heat pump working medium in the tube. The water vapor turns into condensed water and is discharged from the bottom of the material liquid evaporation and concentration chamber. The gas medium leaving the heat pump evaporation system turns into a state with little water vapor and low temperature, and then passes through the GER evaporation chamber and condensation chamber to start the next cycle.
