Abstract

The invention discloses a low-temperature waste heat power generation system based on carbon dioxide-based nanometer miscible high-permeability magnetic fluid. The system can improve the utilization efficiency of low temperature waste heat, recycle the industrial waste heat in lower temperature range, and directly convert heat energy into electric energy, and remove the intermediate conversion link of heat energy-mechanical energy-electric conversion mode; The system has a more efficient energy conversion rate, a lower range of low-temperature waste heat utilization, and a simpler and more compact design. Besides utilizing low-grade heat sources such as cement, steel, thermoelectricity, ceramics, and non-ferrous metals, the system can also utilize new energy sources such as solar energy, geothermal energy, and seawater heat energy to generate electricity.

Description

technical field [0001] The invention relates to the field of low-temperature waste heat power generation, in particular to a low-temperature waste heat power generation system based on carbon dioxide-based nano-mixed phase high magnetic permeability fluid. Background technique [0002] At present, the mainstream power generation method is thermal power based on fossil fuels such as coal and natural gas, but as a non-renewable energy source, fossil fuels will eventually run out one day. Currently, a very promising solution is to use low-grade heat sources to generate electricity. Industries that emit large amounts of industrial waste heat, such as cement, steel, thermoelectricity, ceramics, and nonferrous metals, are not only large emitters of waste heat, but also major emitters of room temperature gases. [0003] At present, the root cause of my country's grim energy situation lies in the low energy efficiency. my country's output efficiency per ton of standard coal is onl...
