Embodiment Construction
[0018] The specific implementation manners provided by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] like figure 1 As shown, an expansion generator system includes: generator 100, expander 101, recuperator 102, oil separator 103, oil collecting bag 104, oil pump 105, condenser 106 and evaporator 107, each device They are connected through pipelines according to the flow direction of the working medium in turn. figure 1 The connection lines between the various components in the diagram represent connecting pipelines, and the direction of the arrow on the connection indicates the flow direction of the working medium in the pipeline.
[0020] The generator 100 is connected to the expander 101 through a coupling 110, and the coupling is used to follow the rotation of the expander to drive the generator to generate electricity. When the expander 101 is working, the expander 101 rotates to drive the generator 100 to...

The invention relates to an expansion generator system. The expansion generator system comprises a power generator, an expansion machine, a heat recover exchanger, an oil separator, an oil pump, a condenser and an evaporator, wherein the expansion machine is connected with the power generator and used for converting heat energy of a gas working medium into mechanical energy for driving the power generator to generate power; the heat recover exchanger is connected with the expansion machine and used for exchanging heat with gas exhausted by the expansion machine; the oil separator is connected with the heat recover exchanger and used for separating heat-exchanged gas into oil and a gas working medium; the oil pump is connected with the oil separator and the expansion machine and used for pumping the separated-out oil back to the expansion machine; the condenser is connected with the oil separator and the heat recover exchanger and used for condensing the gas working medium separated out by the oil separator to form a liquid working medium, and the liquid working medium enters the heat recover exchanger to exchange heat with the gas exhausted by the expansion machine; the evaporator is connected with the heat recover exchanger and the expansion machine and used for evaporating the liquid working medium exchanging heat in the heat recover exchanger to form a gas working medium, and the gas working medium is sucked into the expansion machine. The expansion generator system is high in power generation efficiency and stable in system.
Description
technical field [0001] The invention relates to the technical field of generators, in particular to an expansion generator system. Background technique [0002] With the development of society and economy, energy shortage and global environmental problems are becoming more and more serious. According to statistics, 50% of the heat energy used by humans is finally discharged in the form of low-grade waste heat. The temperature of low-grade waste heat is generally around 200°C, including solar energy, various industrial waste heat, geothermal heat and ocean temperature difference heat, etc. [0003] The use of low-grade waste heat to generate electricity not only helps to solve energy shortages, but also solves thermal pollution to the environment during energy production. Therefore, various new technologies for utilizing low-grade waste heat continue to emerge. Using the principle of Organic Rankine Cycle (ORC) to utilize low-grade waste heat is a method to effectively uti...
