HIGH-EFFICIENCY OCEAN THERMAL ENERGY CONVERSION (OTEC) APPLYING A LIQUID-VAPOR EJECTOR AND A MOTIVE PUMP

摘要

According to the present invention, a high-efficiency ocean thermal energy conversion system applying a distributor, a liquid-vapor ejector, and a motive pump comprises: a vaporizer to allow transported refrigerant liquid to exchange heat with surface layer water to convert the refrigerant liquid into high-temperature high-pressure refrigerant vapor; a liquid-gas separator installed on an exit of the vaporizer to separate the refrigerant in a liquid and a gaseous form; a distributor installed on an entrance of the vaporizer to separate a pipe entering the vaporizer in multiple directions; a turbine to use the refrigerant in a high-pressure gaseous form transported from the liquid-gas separator or the vaporizer to produce power; a motive pump which branches off from the distributor or increases a pressure of the refrigerant in a liquid form separated from the liquid-gas separator; a liquid-vapor ejector to mix the low pressure refrigerant in a gaseous form passing through the turbine and the high pressure refrigerant in a liquid form passing through the motive pump to have an expansion and an compression process; a condenser to exchange heat between the refrigerant mixed by the liquid-vapor ejector and the surface layer water to condense the refrigerant; and a refrigerant circulation pump to increase the pressure of the refrigerant condensed by the condenser to an evaporating pressure and circulate the refrigerant.
