Embodiment Construction

[0007] The lithium bromide unit converts the heat of the heat source into cooling through the absorption and evaporation of water vapor. In the Carnot cycle unit, the heat provided by the heat source heats the refrigerant working medium to form a high-pressure superheated liquid refrigerant, and then pushes the blades to rotate, and the refrigerant releases energy. After entering the radiator, it is cooled by the cooling capacity provided by the lithium bromide unit to form a low-pressure liquid, and then pressurized and pumped into the evaporator again through the throttling unit to enter the next working cycle, while the rotating blades in the Carnot cycle unit drive the generator to generate electricity. The cooler of the lithium bromide unit can be directly coupled with the evaporator of the Carnot cycle unit, or indirectly through the heat exchange unit.

[0008] In the case of indirect coupling, the working substance of the cooling capacity of the Carnot cycle unit can be...

Abstract

The invention provides a temperature different generator which is composed of a heat source and a power generating unit, wherein the generator is formed by a Carnot cycling machine, a lithium bromide set, a generator and a booster pump, wherein the Carnot cycling machine is formed by four parts including a blade, a heat radiator, a throttling unit and an evaporator; and the lithium bromide set is formed by a generator, a condenser, an evaporator, an absorber, a heat exchanger, a circulating pump and the like. The temperature different generator has the beneficial effects that the combined lithium bromide set can expand a low-grade heat source temperature difference at 60-150 DEG C to 100-240 DEG C, and a temperature difference between the heat radiator and the evaporator of the Carnot cycling machine is enlarged, so that a pressure difference of the blade is expanded; and finally, the power generation efficiency is improved to 25-35%, and the temperature different generator can be used for a thermal power plant or other boilers to carry out residual heat power generation and solar power generation.

Description

technical field [0001] The invention relates to a generator, especially a thermoelectric generator. Background technique [0002] The current thermoelectric generators include semiconductor thermoelectric power generation, turbine flash evaporation and refrigerant generators. The conversion efficiency of semiconductor thermoelectric power generation is between 8 and 12%, and the equipment investment value is high, close to 10,000 to 30,000 yuan / kW; The efficiency of the flash type is lower, the operating efficiency is close to about 4%, and the investment value is about 5,000 yuan / kW; while the efficiency of the refrigerant generator is about 15-20%, and the investment value is 0.5-10,000 yuan / kW. [0003] The above structure, when used for waste heat, has a relatively low conversion efficiency when the temperature difference is only between 60 and 150 degrees Celsius, and the investment is relatively high. Contents of the invention [0004] The invention provides a therm...
