Abstract

The invention discloses a work medium phase change enthalpy difference sea water temperature difference motor, in particular to a high-efficiency ocean thermal energy motor which relies on the enthalpy difference property when the phases of two work media change at the same temperature and is manufactured for the purpose of utilizing an enclosed circulation device for converting ocean thermal energy into a driving force and a technology thereof. The motor is mainly characterized in that a work medium in an evaporator (19) absorbs heat from surface sea water and then is compressed into a saturated steam by a high centrifugal compressor (1) and then transfers heat to a work medium of a steam turbine (3) with multiple masses in reverse-flow heat exchangers (15) and (14); the work medium of the steam turbine (3) absorbs high-temperature high-pressure steam and then does work; waste steam enters a condenser (5) and is condensed after releasing heat to deep sea water. The motor realizes that a work medium absorbs heat from surface sea water, is compressed, releases heat and is converted into a high-temperature high-pressure work medium and does work which mostly is mostly output as a driving force to the outside world except ensuring the energy consumption of the compressor and the pumping assistant load. The motor can provide driving force required by islands and ocean industries such as sea water industry, undersea mining and metallurgy and the like, and generates powers and provides cheap electrical power.

Description

technical field [0001] The present invention relates to a marine thermal energy conversion power equipment and theoretical technology manufactured by relying on the enthalpy difference characteristics of two working fluids when they undergo gas-liquid phase transition at the same temperature, using the existing temperature difference between the surface layer and deep layer of seawater and closed circulation. Ocean thermal power engine. Background technique [0002] In known theoretical techniques, the surface temperature of the ocean is higher, while the temperature in the depths is lower. Ocean thermal energy exists in the ocean in the form of this temperature difference. In most tropical and subtropical sea areas, the difference between the surface water temperature and the water temperature at a depth of 1000m is more than 20°C, which is the minimum temperature difference required for thermal energy conversion. The working modes of ocean thermal energy conversion (OTEC...
