According to the power generation device of the turbine expander, disclosed by the invention, the turbine expander is connected with the power generator, compressed air does work, the work can be converted into high-quality electric energy, the purpose of converting low-quality electric energy into the high-quality electric energy can be realized, the method is simple, convenient and pollution-free, and the power generation device has a wide market prospect and a wide development space.
Description
Technical field
The present invention relates to a kind of electricity generating device, especially a kind of turbo-expander electricity generating device.
Background technique
Turbo-expander is that transformation of energy is carried out in the variation of speed while utilizing Working fluid flow, and working medium expands and obtains kinetic energy in the circulation part of turbo-expander, and exports external work by the work wheel shaft, thereby has reduced interior energy and the temperature of decompressor outlet working medium.So at present, turbo-expander be mainly used in refrigerating field, rarely have utilization at power field.
In recent years along with the development of Wind Power Generation Industry, in the short time China and even foundation in the world the wind power stations, many places, still, due to the deficiency of technical capability, the inferior quality of wind-power electricity generation, cause 2/3 electric energy nearly to waste because being connected to the grid.The air energy storage technology is stored energy by compressed-air actuated mode, utilize this technology, the inferior electric energy of wasting in the wind-power electricity generation process can be stored, change into high-quality electric energy through energy again, just can realize grid-connected, promoting the high speed development of Wind Power Generation Industry, is the energy of society's raising high-efficiency cleaning. therefore there are wide market prospects.Yet at present, the technology of utilizing pressurized air to be generated electricity still belongs to blank.
Summary of the invention
The purpose of this invention is to provide a kind of turbo-expander electricity generating device, by pressurized air is carried out to transformation of energy, realize the purpose of the electric energy that output is high-quality.
Technical solution of the present invention is: the turbo-expander electricity generating device comprises generator, retarder, turbo-expander, and the rotor of described three-phase synchronous AC generator and the output terminal of retarder are direct-connected by coupling; The turbine shaft one end fixed turbine impeller of turbo-expander, the other end is connected with the input end of retarder, described turbine shaft is arranged on Bearing Casing by bearing, the two ends of Bearing Casing are arranged on respectively on retarder and turbo-expander, and the volute of described turbo-expander is connected with air supply system.Described generator is three-phase synchronous AC generator, and turbine wheel can be connected on turbine shaft by welding or bolt.Described bearing is two.
The present invention is by being connected turbo-expander with generator, the kinetic energy that compressed air to do work produces, and then change into high-quality electric energy, thereby can reach the ability be connected to the grid, realize the purpose of low-quality electric energy to high-quality electric energy conversion, method is easy, pollution-free, has wide market prospects and development space.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in the figure, the turbo-expander electricity generating device comprises generator 1, retarder 3, turbo-expander 11, and the output terminal of the rotor of described generator 1 and retarder 3 is direct-connected by coupling 2; The turbine shaft 10 1 end fixed turbine impellers of turbo-expander 11, the other end is connected with the input end of retarder 3, described turbine shaft 10 is arranged on Bearing Casing 4 by bearing 9, the two ends of Bearing Casing 4 are arranged on respectively on retarder 3 and turbo-expander 11, and the volute 5 of described turbo-expander 11 is connected with air supply system.Described generator 1 is three-phase synchronous AC generator, and turbine wheel 7 can be connected on turbine shaft 10 by welding or bolt 8.Described bearing 9 is two.
The present invention is when work, and pressurized air enters in turbo-expander 11 by the volute 5 of turbo-expander 11, blows turbine wheel 7 actings after the nozzle ring rectification in volute 5, after turbine shaft 10 and retarder 3, and drive motor work generating; Simultaneously, the air of compression does work because expanding, thereby has reduced interior energy and temperature, and the low temperature of decompressor outlet can reach minus 20 degrees, therefore can also realize refrigerating function.
