The invention discloses a bubble humidification and heat pump cycle coupled sea water desalination system and process method. A heat pump evaporator serves as a dehumidifier of hot wet air, a heat pump condenser supplies heat for air heating and humidifying, and the condensed latent heat of water vapor is recycled by virtue of a heat pump working medium cycle. The air is subjected to bubble humidification by adopting a single-stage sieve plate, seawater circulates on the sieve plate in the humidification process, the energy consumption is reduced, and the fresh water production cost is reduced. The humidification and dehumidification processes are designed in the same tower, the condenser is arranged in seawater on the sieve plate, heat is supplied to the air bubble humidification process, and the heat energy utilization rate is high; and moreover, the evaporator is arranged on the upper part in the tower, the air is subjected to bubble humidification and directly ascends to the outer surface of the evaporator for performing dehumidification, and the air flow path is short. The system device is compact in structure and high in water yield; the system device can be driven by power supply of the power grid and can be independently driven by power generation; and moreover, the system device can be used for coastal and island seawater desalination and can also be used for bitter desalination in interior areas.
Description
technical field [0001] The invention relates to a seawater desalination system and a process method coupled with bubbling humidification and heat pump circulation, and belongs to the technical field of seawater desalination. Background technique [0002] Humidification and dehumidification seawater desalination method is one of the most widely used methods with the least energy consumption among many seawater desalination methods. It has high heat utilization efficiency, and the heating, evaporation and exothermic condensation processes are carried out separately, which is conducive to the improvement and strengthening of each process. , It is also convenient to recover and utilize the latent heat of condensation of water vapor, and is suitable for small seawater desalination devices. At present, the key to the application of humidification and dehumidification is the development and application of efficient humidification, efficient condensation latent heat recovery and adv...
