Low -temperature multi -effect sea water desalinization system

The utility model provides a low -temperature multi -effect sea water desalinization system, former material when former material temperature is less than the material settlement temperature that gets into last effect group evaporimeter, preheated former material through dense extra large water heat exchanger before getting into the low -temperature multi -effect distillation system to reach the default when making former material get into the evaporimeter, adopt to divide imitate the feeding of component section, get into effect group evaporimeter in the front with first effect group evaporimeter at the dense water of back effect group evaporimeter after the dense water heat transfer that dense water heat exchanger retrieved. Can solve the problem that traditional parallel feed flow material sea water rate of recovery is low, reduce the operation and added medicine and power consumption cost, not only solve the not enough of traditional handicraft mode, improved the thermal efficiency of low temperature mult
