Abstract

The invention relates to a sunlight boiler, belonging to the field of high-temperature and high-efficiency utilization of solar energy. It is composed of shaft-push or side-push type double-shaft sun-tracking machine, vacuum pan heat collector component, grid-plate or mirror-frame type condenser lens component and various types of machine frame components, and is invented with immobile interface. The solar energy high-temperature steam generator can be used in the field of solar energy high-temperature photo-thermal power generation or solar energy heating, or can be used for industrially generating high-temperature steam and the like. The butterfly-type Stirling generator overcomes the defects that the butterfly-type Stirling generator is complex in structure and high in cost, the Stirling generator is arranged in a high altitude due to the fact that air is blown to dissipate heat, and the tower-type photo-thermal power generation station is too high in power generation cost and large in occupied area due to the fact that photo-thermal conversion efficiency is too low, and reflected sunlight paths are too long to be aligned with a receiver. In addition, the solar energy solar water heater has the advantages of simple structure, low cost, high light-heat conversion efficiency of 80%, capability of generating high temperature, convenience for external heat transmission and underground heat storage and the like.

The two ends of the carrier rack 8 are connected with the middle part of the upper mirror ring of the mirror frame type collecting mirror distributed on the two sides of the sun-tracking machine, so that the type is called as an 'upper-connecting-middle' solar boiler machine, namely: "upper" means that the carrier is directly or indirectly attached to the height axis on the one hand, and "middle" means that the carrier is directly or indirectly attached to the middle of the concentrator frame on the other hand. Hereinafter, the terms "upper side", "lower middle side", "lower side", "side middle side" and "side" are similar to each other, and the explanation thereof will not be repeated. In addition, only the shaft-push type sun tracker, that is, the sun tracker in which the object carrier is fixedly connected with the height shaft and the light collector (sometimes including the heat collector) is pushed by the height shaft to rotate to track the sun, has six categories; the tracking devices carried by the push-by-follower sun tracker do not have these classifications.

When the energy collecting system operates on double-shaft sun tracking, the two pairs of external interfaces are almost motionless so as to be communicated with a pipeline externally, because the positioner 14 fixedly connected with the boiler tube frame 12 (namely fixedly connected with the vacuum boiler tube part) is movably connected in the figure 1, and the central line of the tube part and the central line of the height axis can be ensured to be coincident or approximately coincident, so that the boiler tube frame 12 and the condenser 18 can track the sun in a rotating way around the central line of the vacuum boiler 16 and the boiler tube 13 thereof, and on the other hand, when the condenser rotates around the azimuth axis 5 to track the sun in the azimuth direction on the horizontal plane, the external interfaces are positioned at the extension line of the central line of the azimuth axis or at the adjacent position, so that the rotating radius of the external interfaces in the horizontal direction is extremely tiny and is approximately motionless, namely motionless interfaces.
