DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to figure, a solar thermodynamic power generator according to a preferred embodiment of the present invention is illustrated, comprising: a quartz window 3 placed on a metal shell 1 to form an electromagnetic resonant cavity structure for receiving solar energy; a ceramic conduit 4 placed in the metal shell 1; wherein a working medium is heated in the ceramic conduit by the solar energy; a heat exchanger 14 placed in a vacuum insulation oil tank 15; wherein the heat exchanger 14 communicates with the ceramic conduit 4 through a first pipeline and a second pipeline; the working medium flows into the heat exchanger 14 through the first pipeline, and flows back to the ceramic conduit 4 from the second pipeline, so as to transfer thermal energy from the ceramic conduit 4 to the heat exchanger 14; a steam generator 13 placed in the vacuum insulation oil tank 15; wherein the steam generator 13 is heated by the heat exchanger 14 to generate steam; a ceramic heating tube 34 placed in a combustion chamber 23; wherein the combustion chamber 23 heats the ceramic heating tube 34 through combustion; the ceramic heating tube 34 communicates with the vacuum insulation oil tank 15 through a third pipeline and a fourth pipeline; oil in the vacuum insulation oil tank 15 flows into the ceramic heating tube 34 through the third pipeline, and flows back to the vacuum insulation oil tank 15 through the fourth pipeline after being heated, thereby maintaining a temperature in the vacuum insulation oil tank 15 within a preset range; and a turbine 9 communicating with the steam generator 13 through a fifth pipeline and a sixth pipeline; wherein the steam flows into the turbine 9 through the fifth pipeline, and flows back to the steam generator 13 through the sixth pipeline to drive the turbine 9; the turbine 9 further drives a turbine generator 33 to generate electricity.

According to the present invention, a specially designed electromagnetic wave resonant cavity is used to absorb solar energy. Based on the molecular wave resonance effect, the energy absorption efficiency can be significantly enhanced. The enhanced thermal energy is transferred to the steam generator 13 in the vacuum insulation oil tank 15 through the heat exchanger 14, so that the working medium of the steam generator 13 generates high-pressure steam, thereby driving the turbine to generate electricity.

Specifically, a resonant cavity electrode 2 is also placed in the metal shell 1; the resonant cavity electrode 2 is connected to an electromagnetic wave transmitter 7 to emit electromagnetic waves in the electromagnetic resonant cavity structure. The vacuum insulation oil tank 15 adopts a high- vacuum heat- insulation method, which uses high-strength materials as external protection. There are several sealing ports on the vacuum insulation oil tank 15 to communicate with each part of the system.

Specifically, the first pipeline extends into the vacuum insulation oil tank 15 through a first sealing port 20; the second pipeline extends into the vacuum insulation oil tank 15 through a second sealing port 21; the third pipeline extends into the vacuum insulation oil tank 15 through a third sealing port 18; the fourth pipeline extends into the vacuum insulation oil tank 15 through a fourth sealing port 19; the fifth pipeline extends into the vacuum insulation oil tank 15 through a fifth sealing port 16; the sixth pipeline extends into the vacuum insulation tank 15 through a sixth sealing port 17.

Specifically, a working medium storage tank 6 and a first circulating pump 5 are arranged on the second pipeline in sequence; a second circulating pump 32 is arranged on the third pipeline; a pressure booster 8 is arranged on the fifth pipeline; a cooling tower 10, a storage tank 11 and a third circulation pump 12 are arranged on the sixth pipeline in sequence.

Generally, an output power of the turbine 9 is proportional to a steam flow rate of the working medium, and a change of air pressure has little influence on the output power. Therefore, the present invention arranges the pressure booster 8 at a front end of the turbine to keep the steam pressure stable.

Specifically, the combustion chamber 23 is equipped with an exhaust valve 22; the combustion chamber 23 is connected to an internal combustion generator 24 to generate electricity through combustion.

Specifically, a first fuel tank 26 sends a first fuel into a gas flow valve automatic control box 31 through a first relief valve 29; a second fuel tank 27 sends a second fuel into the gas flow valve automatic control box 31 through a second relief valve 28; the gas flow valve automatic control box 31 mixes the first fuel with the first fuel through a gas mixing chamber 30 to form a mixed fuel; then the gas flow valve automatic control box 31 sends the mixed fuel into the combustion chamber 23 through a program-controlled ignition device 25 for combustion.

Specifically, the first fuel is a hydrogen fuel, and the second fuel is a hydrogen silicon fuel.

Specifically, the preset range of the temperature in the vacuum insulation oil tank 15 is 115-120°C.

The hydrogen fuel (mixed hydrogen and hydrogen silicon fuel) can be used for auxiliary power generation through the internal combustion generator 24; or direct burned in the vacuum-enclosed combustion chamber 23 for rapidly heating the ceramic heating tube 34, in such a manner that the temperature of the vacuum insulation oil tank 15 is maintained at 115-120°C. With the continuously circulating working medium, critical supersaturated steam (working pressure generally exceeding 3.5MPa) will be generated to drive the turbine 9 to generate electricity.

Specifically, the steam generator 13 comprises a porous graphene ceramic material and a copper conduit; a diameter of the porous graphene ceramic material is about 20mm, and an internal pore size thereof is 2-3mm.

The porous graphene ceramic material adopts a new carbon nano -sintering technology, which has excellent thermal conductivity, compression resistance, corrosion resistance, and no cracking. The internal porous distribution is uniform with a pore size of 2-3mm, and the diameter is about 20mm. Usually, multiple layers of the copper conduit should be provided in the vacuum insulation oil tank 15, which are connected to each other and are generally several tens of meters long (a volume must be greater than 1 cubic meter, and a certain flow rate can be maintained, i.e. above 1 cubic meter per second). All the copper conduits are immersed under the oil level.

Compared with conventional solar power generation, the present invention is environmentally friendly, safe, low-cost, high-efficiency, pollution-free, emission-free, and not affected by natural weather or environment. Like natural gas, the present invention can be configured to perform grid-connected power generation. Furthermore, after the hydrogen fuel and the hydrogen silicon fuel are mixed and burned, waste hydrogen can be recycled and reused, which greatly reduces the consumption of the hydrogen fuel. The present invention explores a novel and effective technical route to realize the ideal development of new energy. It will thus be seen that the objects of the present invention have been fully and effectively accomplished.
