Solar Automatic soaking and gathering-heat pipe, slot-typed assembly, thermal power generating system and craft

Abstract

The invention relates to a solar automatic soaking and gathering-heat pipe, a slot-typed assembly, a thermal power generating system and a craft. The solar automatic soaking and gathering-heat pipe comprises a glass tube and an absorption tube which is installed inside the glass tube and is coated with an endothermic layer. Vacuum is arranged between the glass tube and the absorption tube. The solar automatic soaking and gathering-heat pipe is characterized in that segregation board which is used for enabling fluid to turn flow up and down alternatively in the absorption tube and is installed inside the inner chamber of the absorption tube. The segregation board is in a heliciform and is fixed in the absorption tube enabling the solar automatic soaking and gathering-heat pipe to be filled with water to heat directly without the worry of booster. Meanwhile, the electrical power generating system and the craft through photo-thermal supplementary electricity generation enables the photo-thermal supplementary power station to be unaffected by the weather so that the electricity can be generated steadily at night or when the sunlight is inadequate. Energy conservation and environment protection can be achieved.

Description

technical field [0001] The invention relates to a thermal power generation process, device / system and process for directly passing water through solar trough heat collecting tubes, and belongs to the technical field of solar thermal power generation. Background technique [0002] Solar energy has wide distribution, unlimited reserves, clean collection and utilization, CO 2 The advantages of zero emissions have attracted widespread attention. For a long time, in the field of solar thermal power generation technology, there have been three power generation modes, namely tower type, dish type, and trough type (including parabolic mirror trough type and Fresnel mirror trough type). [0003] In prior art trough solar thermal power generation systems, steam turbines are used to finally drive the motor to generate electricity, and the working medium is water vapor. However, in the current existing technology, in the vacuum heat collecting tube of the trough solar thermal power ge...

Problems solved by technology

And if the absorption tube 1b3 is filled with water, when the water temperature rises above 100°C, the water will be easily vaporized to produce water vapor, and the vacuum heat collection tube of the trough system is very long and placed horizontally. On the surface, it will form a two-phase flow state in which the upper half is steam and the lower half is water in the absorption tube 1b3. The thermal conductivity of steam is very different from that of liquid water. The temperature difference is very large, and a large internal stress is generated due to thermal expansion and cold contraction, and a tube explosion accident that destroys the vacuum heat collecting tube occurs
