The Analysis Of Low-temperature Multi-effect Distillation In Power Plant

As low-temperature multi-effect distillation with thermal vapor compression has some technical advantages through the possibility of utilizing low-temperature heat resource,increasing gained output ratio and reducing water cost,it was studied in the dissertation.By analyzing and calculating,it can be concluded the appliance range of single-stage steam ejector and double-stage steam ejector.Based on four-effect low-temperature desalination device in SIDEM corporation,France,it was put forward a new low-temperature multi-effect distillation with thermal vapor compression and obtained its optimal design in the given initial parameter.The conclusions provide a significant guidance in the specific extent of engineering.
