Description
Technical Field
The invention belongs to the technical field of photo-thermal power generation, and particularly relates to a novel photo-thermal heat collector.
Background
Generally, solar photo-thermal power generation forms include four systems of a groove type, a tower type, a disc type (disc type) and a fresnel type. The trough type solar thermal power generation system is totally called as a trough type parabolic reflector solar thermal power generation system, and a plurality of trough type parabolic concentrating collectors are arranged in series and parallel to heat working media to generate superheated steam so as to drive a turbine generator set to generate power. To improve the efficiency and normal operation of a trough solar thermal power generation system, control problems related to two aspects are involved, one is an automatic tracking device, which requires that a trough concentrator is aligned with the sun at all times so as to ensure maximum absorption of solar energy from the source, and the statistical tracking is 37.7% higher than the energy obtained by non-tracking. And the other is to control the temperature and pressure of the heat transfer liquid loop, so as to meet the requirements of the steam turbine and realize the normal power generation of the system.
The traditional Fresnel working principle is similar to that of trough type photo-thermal power generation, and only a condensing lens with a Fresnel structure is adopted to replace a parabolic lens. This makes it relatively inexpensive but also reduces efficiency. Because the condensation multiple of the system is only tens of times, the quality of the heated water vapor is not high, so that the annual power generation efficiency of the whole system can only reach about 10 percent; but because the system has the characteristics of simple structure, direct use of heat conducting medium to generate steam and the like, the construction and maintenance costs are relatively low.
The glass vacuum tube heat collecting tube widely used at present is formed by sleeving a stainless steel tube in a glass outer tube, sealing the two ends of the glass tube by using a plugging piece, and vacuumizing the space between the stainless steel tubes. The expansion rate of the metal is larger than that of glass, because the metal pipe generates radial displacement after expanding at the inner side to extrude the glass pipe at the outer side, the working temperature of the heat collecting pipe with the structure can only reach about 550 ℃ due to the problems of plugging materials and structures, and meanwhile, the expansion joint is required to be arranged at the joint of the heat collecting pipe for eliminating expansion stress due to the displacement generated by the axial expansion of the heat collecting pipe.
