Abstract

The invention discloses a medium-high temperature heat source-oriented LMMHD/ORC coupled power generation system with a multi-loop fault prevention mechanism and a working method thereof. The system can take a deep sea nuclear reactor as a heat source, through coupling with a deep sea nuclear reactor, a liquid metal coolant and a low-boiling-point working medium are mixed with a mixer, so that thelow-boiling-point working medium is vaporized to push liquid metal to generate power through a magnetofluid power generation channel, a mixed two-phase working medium after power generation is separated in a separator, a gas-state low-boiling-point working medium is used for pushing a turbine to rotate to further generate power, two power generation modes are ingeniously combined, gradient utilization of energy is achieved, and in addition, if one power generation device breaks down, the other power generation device can be used for continuously generating power through active control, and electric energy is continuously and stably output. According to the system, the power generation output power and stability of the deep sea nuclear power supply system can be remarkably improved, and the requirement for deep sea environment detection is better met.

Description

Technical field[0001]The invention relates to an LMMHD (Liquid Metal Magneto-Hydro-Dynamics) / ORC (Organic Rankine Cycle) coupled power generation system and its working method, and in particular to a multi-circuit failure prevention mechanism The LMMHD / ORC coupling power generation system and its working method belong to the field of comprehensive energy utilization.Background technique[0002]The ocean is the general term for the widest body of water on the earth, and its area accounts for approximately 71% of the earth's surface area. At present, human activities basically stay on the surface of the ocean, while only 5% of the seabed has been explored by humans. The seabed contains huge mineral resources. 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 for deep-sea expl...
