Problems solved by technology

[0004] In the existing power generation system, the thermal efficiency is low, resulting in a great waste of resources. For the power plant, the cost increases. Because the latent heat of water vapor is emitted into the atmosphere, it has a great impact on the environment around the power plant; in a...

[0139] Below in conjunction with accompanying drawing, the present invention is further described:

[0140] see Figure 19 : This picture shows the second basic cycle prime mover, using low boiling point medium such as carbon dioxide gas in the heat flow boiler 1 tube side, the high pressure and low temperature low boiling point medium absorbs the shell side heat flow heat and then gasifies itself, and enters the expansion work unit 2 for decompression Expansion, transforming pressure energy into kinetic energy to push the expansion work unit 2 to move and do work. Various working machines, such as compressors, can be driven through the output shaft of the expansion unit 2 and the transmission unit 3, and at the same time drive the compression unit 4 to the gaseous low boiling point For medium compression, an electric motor can also be set to drive the compression unit 4 separately. The temperature of the low-boiling-point medium that has done the work is reduced to the lique...

Abstract

The invention relates to a low-grade heat flow prime motor, a power generating system and a method thereof; the low-grade heat flow prime motor comprises a heat flow boiler unit, an expansion working unit and a pressing unit, after mediums with low boiling point pass through the heat flow boiler unit and exchange heat with the low-grade heat flow, the mediums enter in the expansion working unit to push moving parts to move, and then pressurization is carried out to lead the mediums with low boiling point to flow back to the heat flow boiler unit to form working circulation; the technical proposal provided by the invention is suitable for 30-400 DEG C of temperature range of the heat source, the pressure range is from positive pressure to negative pressure; therefore, the waste heat energy can be fully recovered and utilized, the heat source utilization efficiency is improved, the resources are saved and the environment is protected.

Description

Technical field: [0001] The invention relates to a utilization method of low-grade heat flow, especially a system and method for converting low-grade heat flow into electric energy and mechanical energy. Background technique: [0002] Exhaust steam (gas) of various drying equipment, flue gas of various furnaces, engine exhaust of various fuels, exhaust air of air conditioners, various fluids with a certain temperature, etc. all have a lot of heat. Because it cannot be utilized, it is called low-grade heat energy or low-grade heat energy and is discharged into the atmosphere, which is an important reason for global warming. [0003] The current large-capacity power generation technology thermal power generation uses water as the working medium to convert the chemical energy of the fuel into electrical energy, but only the sensible heat of water vapor can be converted into electrical energy. The latent heat is distributed into the atmosphere through circulating cooling water, ...
