Problems solved by technology

[0002] At present, the development of solar power generation and heat utilization technology is relatively fast. In the field of solar heat utilization, solar low-temperature water heaters develop rapidly, but in the field of medium and high temperature, there are few applications due to high technical costs.
Solar power generation mainly includes solar photovoltaic power generation (solar cells) and solar thermal power generation, but the common problem is still the high cost of power generation
The raw material cost of the former crystalline silicon is difficult to break through. Whether the latter is concentrating with a dish reflector, a trough reflector or a tower planar reflector, the general idea is to increase the size of a single heat collector, and each reflector Using an independent tracking control system, the result is that the complex and bulky heat collection system is always difficult to reduce the cost of power generation for solar energy with a very low energy flux density
[0003] At present, the thermal units used in solar thermal power generation have low thermal efficiency due to the inability to achieve large capa

Example Embodiment

[0065] Embodiment 1: In order to realize low-cost solar reflectors tracking and concentrating, adopt as attached figure 1 In the connecting rod linkage mode shown, in order to realize reflection and light concentrating, each reflector 1 is installed at an appropriate installation angle, and under the action of the movement of the connecting rod 2, the parallel rocker 3 parallel to each other realizes synchronous deflection. The deflection of the sun's rays makes the reflected light change synchronously and focus on the receiver 4, forming a parallel link tracking and concentrating system. Generally, the two-dimensional deflection of the entire array is controlled by connecting rods in the vertical and horizontal directions. figure 1 Only one row of mirrors is shown in the figure, and when arranged in multiple rows, it becomes a mirror concentrating array. When the parallel linkage mechanism of each row is horizontal, the longitudinal deflection of the mirror is realized by the...

Example Embodiment

[0075]Embodiment 2: as attached Figure 13 The shown simple power heat pipe circulation system is filled with a part of the working medium (which can be water or other suitable solutions), and vacuumizes to remove the air seal so that the working medium can evaporate at a lower temperature. When the heater 22 is heated When the working medium starts to evaporate and expand to generate pressure, the check valve 21 is reversely closed, and the working medium starts to flow to the condenser 24, and after passing through the condenser, it is condensed into a liquid state and enters the return pipe 25. When the working medium in the heater evaporates, its internal The pressure gradually drops, and finally the pressure of the gas working medium before and after the condenser is close to the same, and the whole circuit becomes a connector, and the liquid working medium in the return pipe pushes the check valve to lead forward and enter the heater to start a new cycle. The graphics of...

[0086] Embodiment 3: as attached Figure 18 As shown, a thermodynamic booster power heat pipe cycle power generation system can be considered as a cycle system in which a thermodynamic booster system is used to replace the feed water pump on the basis of an ordinary thermal power generation system. The working process of the thermodynamic booster is:

[0087] a. Hydration. When the thermal booster 41 needs to replenish water, open the steam vent valve 43 of the condensed water tank 44 and close other valves, and the low-pressure liquid working medium from the condensed water tank 44 enters the booster 41 through the check valve 42 due to the principle of the connector.

[0088] b. Boost. After the booster replenishment is completed, the steam vent valve 43 is closed, and the steam extraction valve 46 is opened. Close the steam extraction valve 46 during the time, open the steam vent valve 37 with the evaporator 39 to continue heating and boosting.

[0089] c. Water supply. ...
