Description
Technical field
The invention belongs to solar energy heat utilization technical field, particularly a kind of slot light collection solar energy heat collection pipe and assembly technology thereof with compensation sealing structure.
Background technology
The slot light collection solar electricity generation system is mainly by slot light collection solar thermal collection system, hot transmission and exchange system, electricity generation system, heat reservoir and concurrent heating system, and wherein the slot light collection solar thermal collection system is the key core part of this electricity generation system.The slot light collection solar thermal collection system mainly is made up of parabolic mirror, high-temperature vacuum heat-collecting tube, daylight tracking and fluid power system, supporting mechanism and high-temperature medium transmission system.The light of parabolic mirror reflects is to converge on the line, on this line, high-temperature vacuum heat-collecting tube is housed.
High-temperature vacuum heat-collecting tube; Also be solar energy heat collection pipe; Be the core component of slot light collection solar thermal collection system, this thermal-collecting tube is made up of outer layer glass tube, inner core stainless steel tube and vacuum seal joint, and the quality of these three parts relates to photo-thermal transformation efficiency and heat loss rate.Wherein the sealing technology of the high-temperature vacuum heat-collecting tube of outer layer glass tube and inner core stainless steel tube composition is a most key difficult problem during high-temperature heat-collection pipe is made, and its quality has directly determined the life-span (generally requiring service life more than 20 years) and the performance of thermal-collecting tube.The optically focused of slot light collection solar thermal collection system is more about 20 to 80 than scope, about 400 ℃ of the highest heat build-up temperature.Since in the time of 400 ℃, the stainless coefficient of expansion commonly used (α=1.6 * 10-5/ ℃) and the high silicon boron glass coefficient of expansion (α=3.3 * 10
-6/ ℃) both coefficient of expansion difference is very big; And glass is fragile material, and thermal-collecting tube length is generally 4000～5000mm, and the long-term work temperature reaches 400 ℃; Therefore seal pipe in glass outer tube and the stainless steel; And the formation vacuum, reduce the thermal-collecting tube thermal loss, Here it is makes the key technology of thermal-collecting tube.The external kovar alloy (4J29) that adopts gets up glass-to-metal seal as transition piece.Because the coefficient of expansion of kovar alloy approaches the silicon boron glass, its welding performance and functional reliability are good, but the price of kovar alloy is very expensive, thereby its preparation cost is very high.Like patent publication No. is that the patent of invention of CN101135501 discloses a kind of high-temperature solar thermal-collecting tube and manufacturing process thereof; This thermal-collecting tube comprises glass outer tube and coaxial metal inner pipe; Bellows and metal inner pipe that connector will have the expansion compensation effect link together; The other end of bellows and metal-glass transition piece can cut down loops welded, can cut down ring and carry out sealing-in with glass tube again.This can cut down ring and promptly adopt expensive kovar alloy (4J29) to guarantee sealing, can cut down in the ring process but process, and also has surplus and leftover pieces, causes expensive kovar alloy waste, and cost further increases; And the intermediate location welding quality requires high, and the Non-Destructive Testing difficulty is big.
This shows; The metal tube of solar energy heat collection pipe and the method for sealing of glass tube adopt metal bellows slowly-releasing longitudinal dilatation stress, kovar alloy transition and weld with glass tube; But there are swelling stress and welding stress, in use, are prone to produce stress rupture.
Summary of the invention
The technical problem that the present invention will solve is: in order to solve the deficiency of above-mentioned prior art; The present invention provides a kind of stress rupture of avoiding; The slot light collection solar energy heat collection pipe low-cost, that sealing reliability is high with compensation sealing structure, and a kind of fabrication yield is high; Processing step is simple, this thermal-collecting tube assembly technology that human cost is low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of slot light collection solar energy heat collection pipe with compensation sealing structure; It has the coating stainless steel tube; The coating stainless steel tube is set with coating silicon boron glass pipe outward; Coating stainless steel tube two ends all are set with the stainless steel end socket, and coating stainless steel tube outer wall and stainless steel end socket are tightly connected; Coating silicon boron glass pipe and stainless steel end socket are slidingly connected; Be set with high-temperature-resisting silicon rubber compensation cover on the stainless steel end socket, the two ends of high-temperature-resisting silicon rubber compensation cover are tightly connected with coating silicon boron glass pipe and stainless steel end socket respectively; Be provided with between coating stainless steel tube, coating silicon boron glass pipe and the stainless steel end socket and be used for heat insulation vacuum chamber.
