Embodiment 1

[0049] Embodiment 1: Single impeller generator with booster cavity

[0050] Such as image 3 As shown, the open impeller 2 is set in a housing 9, the fluid enters from the fluid inlet 7, and is sprayed on the impeller 2 through the nozzle 5 to push the impeller 2 to rotate. After the impeller drives the rotating shaft 3 to rotate, it is driven and arranged on the rotating shaft The rotor 11 of the generator rotates to form mutual motion with the stator 12 of the generator. The fluid sprays the nozzle 5 onto the impeller to convert the kinetic energy of the fluid into mechanical energy. The rotor and stator of the generator convert the mechanical energy into electrical energy to realize the power generation of the fluid. .

[0051] After the fluid is discharged from the fluid outlet 8, it enters the vortex chamber and is discharged after being pressurized.

[0052] In this case, R123 is used as the working medium, and the generating power is 5kw.

Embodiment 2

[0053] Embodiment 2: impeller generator with gearbox

[0054] Such as Figure 4 As shown, the fluid working medium for power generation in this example is high-pressure low-temperature organic working medium R134a. The fluid enters the cavity from the fluid inlet 7 and is sprayed onto the impeller 2 through the nozzle 5. The fluid is sprayed and expanded in the impeller to push the rotating shaft 3 Rotate, the rotating shaft converts the rotational speed to 3000 revolutions through the gearbox body 10, and the generator rotor 11 and the generator stator 12 are connected to the gearbox body 10, and the relative motion of the rotor and the stator generates electric energy, realizing the conversion of the kinetic energy of the fluid into electric energy .

[0055] In the above cases, liquid, gas, plasma, or a mixture of liquid and gas can be used to generate electricity, so that the waste heat and pressure can be fully utilized, or supplemented by solar energy, shallow surface t...

Abstract

The invention aims to provide a fluid impeller generator, which aims to convert motion energy of fluid into mechanical energy by expanding the fluid to work on an impeller and convert the mechanical energy into electric energy trough the motion of a rotator and a stator of the generator. The fluid is liquid, gas, supercritical gas, plasma and a mixture thereof. The invention also aims to provide a method for converting the motion energy of the fluid into electric energy. The fluid impeller generator is particularly suitable for small generating equipment and can generate power of 1w to 3,000 kw, preferably 5 to 200kw, and is suitable for generating power by using solar energy, waste heat, excessive pressure, and low-grade heat of terrestrial heat, and power generation which is realized by sampling a low-temperature organic working medium, particularly power generation realized by using an 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 electricity, especially the equipment and method for using impellers to generate electricity. 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 settings are the s...
