열압축기를 채용한 다중효용 담수설비의 운전특성에 관한 연구(1보)

The core design technology for the multi-effect desalination plant using the thermo compressor (MED-TVC) was investigated by the performance test of multi effect desalination plant in this paper. The final G.O.R (gain of output ratio) of MED-TVC type desalination plant is strongly affected by the performance of thermo-vapor compressor. The present experiments for the desalinating capacity and G.O.R were obtained for the range of the motive steam pressure, 266.0, 250.0, 230.0 and 200.0 kPa. And as a practical problem, to investigate the influence of the sea water temperature to the G.O.R, the inlet steam temperature of the suction water vapor was changed in the range of 311.2~324.2 K in the present experiment. Through the experiments, the maximum value of G.O.R was 8.5 at the condition of the motive steam pressure, 136.0 ㎪ and the minimum value of G.O.R was 8.1 at the condition of the motive steam pressure, 266.0 ㎪. And it was confirmed that the range of desalination capacity was 355.2~264.0 ton/day in the normal operation condition.
