Abstract

The invention discloses a multi-effect evaporative sea water desalinating device with a hybrid process, and belongs to the technical field of sea water desalinating and heat exchange equipment. Compared with the multi-effect evaporative sea water desalinating device with a parallel feeding process, the multi-effect evaporative sea water desalinating device with the hybrid process can ensure the concentration factor of the device and the optimal spraying density of each evaporator/condenser; the water inlet temperature of a single-effect evaporator/condenser can be increased; and the capacity of the device is also improved. Compared with the multi-effect evaporative sea water desalinating device with a grouped reflux feeding process, the water inlet salinity of the single-effect evaporator/condenser can be reduced; the scaling risk of a heat transfer tube is greatly reduced; the maintenance load is reduced; and the energy consumption of a pump is reduced. Meanwhile, non-condensed gas in the sea water is released in a last-effect low-temperature evaporator/condenser; and the non-condensed gas does not enter each-effect evaporator/condenser. Therefore, corrosion of the non-condensed gas on the equipment and adverse effects on heat transfer are reduced; and the operation reliability of the device is increased by simplifying a pumping design of the non-condensed gas.
