Abstract

The invention aims to provide a fluid motor of a single-screw fluid power generator. The fluid motor is characterized by converting the energy of motion of the fluid to mechanical energy by a single-screw expansion structure and converting the mechanical energy to electric energy through motions of stators and rotors, wherein the fluid is one or a mixture of liquid, gas, supercritical fluid and plasma. The invention also aims to provide a method for converting the energy of motion of the fluid to electric energy. The method is characterized by converting the energy of motion of the fluid to mechanical energy by a single-screw expansion structure and converting the mechanical energy to electric energy through motions of stators and rotors. The generator and method are especially suitable for small-sized power generating equipment, can generate power of 1w-3000kw, preferably 50-3000kw, is suitable for generating power by utilizing the low-grade heat energy of solar energy, waste heat, excess pressure and terrestrial heat and is suitable for generating power by sampling low-temperature organic working media, especially by organic Rankine cycle.

Description

technical field [0001] The invention relates to power generation equipment, which can use working media such as liquid or gas to generate power, especially the device and method for generating power by using single-screw star wheel expansion. Background technique [0002] The existing power generation technology mainly uses steam as the working medium to generate electricity. The main working medium is water. The nozzles are set on the stator without movement, and the blades are set on the rotor. The steam injected by the nozzles drives the blades to rotate and generate electricity. The existing technology is mainly generator sets above 100KW, and there is no suitable unit for miniaturization. [0003] The Rankine cycle (ORC) generator set using low-temperature organic matter is suitable for low-temperature heat sources and small-scale power generation, but it is mainly to miniaturize the existing large-scale steam power generation equipment, and its nozzle and blade setting...
