lmmhd/orc coupled power generation system and its working method

Abstract

The invention discloses an LMMHD / ORC coupled power generation system with a multi-circuit fault prevention mechanism and a working method thereof for medium and high temperature heat sources. The system can use a deep-sea nuclear reactor as a heat source. By coupling with the deep-sea nuclear reactor, the liquid metal coolant and the low-boiling point working fluid are mixed in the mixer, so that the low-boiling point working medium is vaporized to push the liquid metal to generate electricity through the magnetic fluid power generation channel, and the mixed two-phase working fluid after power generation is in the separator Intermediate separation, using gaseous low-boiling-point working fluid to drive the steam turbine to rotate for further power generation, cleverly combining the two power generation methods to achieve energy cascade utilization, in addition, if one of the power generation devices fails, the other can also be used through active control The power generating device continues to generate electricity and continuously and stably outputs electric energy. The invention can significantly improve the generating output power and stability of the deep-sea nuclear power supply system, and better meet the requirements of deep-sea environment detection.

Description

technical field [0001] The invention relates to an LMMHD (Liquid Metal Magneto-Hydro-Dynamics) / ORC (Organic Rankine Cycle) coupled power generation system and a working method thereof, in particular to a multi-circuit fault prevention mechanism An LMMHD / ORC coupled power generation system and a working method thereof belong to the field of comprehensive utilization of energy. Background technique [0002] The ocean is the collective name for the most extensive body of water on Earth, covering approximately 71% of the Earth's surface area. At present, human activities basically stay on the surface of the ocean, and only 5% of the seabed that humans have explored. The seabed contains huge mineral resources. The investigation and utilization of seabed mineral resources is the need for the sustainable development of our entire economy and society. However, at present, the insufficient endurance of deep-sea equipment is still a technical bottleneck that needs to be overcome in d...
