Description
Technical field
The utility model belongs to technical field of solar utilization technique, is specifically related to the trough type solar heat-collector that a kind of focal line is the axle center.
Background technology
For a long time, people are just making great efforts research and utilization solar energy always.The solar energy that the earth received accounts for about 2 part per billion of whole energy of sending on sun surface, and these energy are equivalent to ten thousand times of the 3-4 of global required gross energy, are inexhaustible.Therefore just have various solar thermal collectors to begin to be born as far back as 20 beginnings of the century, wherein comparatively representative is exactly that US publication is: the patent document of US1683266.It discloses a kind of solar thermal collector, and this heat collector can reach the purpose of thermal-arrest substantially, but its rotation track and tooth bar separately design therefore complex structure; Drive to drive worm and gear that tooth bar rotates have only one promptly one support stress point, connect therefore that soundness is poor, the dynamics balance was also poor when driven by motor was rotated; As adopt the supporting construction more than two groups to drive, then the driving of each group worm and gear all needs to drive with a motor, must bring the control difficulty; And the shell of this heat collector is very huge, so production cost is high and inconvenient maintenance, and its reflective groove is semicircle simultaneously, and therefore the reflection luminous energy that can utilize is also few.
Along with development of science and technology, people constantly research and develop, and have occurred various forms of solar thermal collectors so far.The thermal-collecting tube of heat collector commonly used all adopts swivel joint now, when heat collector is worked, because thermal-collecting tube is subjected to high temperature action, therefore can make the swivel joint at two ends expand outwardly, thereby produce leakage of oil (steam) phenomenon.In numerous modes of middle high-temp solar heat collector, because trough type solar heat-collector can focus on sunlight on the line, produce the high temperature more than 800 degrees centigrade, it is simple in structure, has obtained using widely.But because it is bulky, windage is also big, and the structure of respective strengths can cause the required power of tracking also big, so follow the tracks of driving force based on hydraulic pressure, hydraulic system must cause cost to increase problems such as maintenance cost height.Secondly the thermal-collecting tube of this groove type solar moves with condenser groove, must cause the loss of the connection pipe fitting on it, and these solar thermal collectors require the high increase that must cause production cost to the rigidity of the structure of stretching frame, and occur the appearance of the problems such as instability, track displacement of hydraulic system easily.And the thermal-collecting tube of this heat collector is to be fixed on the reflective groove, when reflective groove rotates, thermal-collecting tube also rotates together, so the support top of thermal-collecting tube can keep off luminous energy set place of reflecting at reflective groove, so this part a plurality of direction converges and the energy that comes can not effectively be utilized.For example Chinese publication number is: the patent document of CN282865621A, it discloses a kind of heat collector that is used for the solar power plant, this heat collector has mainly solved the technical problem that existing heat collector bears the mechanical load difference when having gathered existing heat collector plurality of advantages, but this heat collector also exists many technical disadvantages.At first the reflective groove of this heat collector drives shell and thermal-collecting tube by a motor and rotates, and its enclosure volume is huge, therefore needs power very strong just passable, and it is few and inhomogeneous to support stress point when rotating, and stability is very poor.Secondly the thermal-collecting tube of this heat collector is fixed on the reflective groove by support, this support is vertical the connection with thermal-collecting tube, therefore this support top and thermal-collecting tube proximity have been blocked the light of reflective groove from a plurality of reflections, and the zone that this is blocked is high-temperature area just, and the thermal-collecting tube length ordinary circumstance that this section is blocked reaches 20cm to 50cm, therefore the heat energy in this section high-temperature region is wasted, and can not utilize the photo-thermal that is reflected to greatest extent.Therefore this heat collector enclosure volume is huge, poor stability when entire equipment is rotated, and power demand is big, and production cost is high and assemble, safeguard very inconvenient.

Above-mentioned metal inner pipe 19 adopts the high-thermal conductive metal materials to make and the selective absorption plated film of its outer surface, and preferably metal ion or metal oxide are as titanium oxide, black chromium, black cobalt, tri-iron tetroxide, alundum (Al, aluminium nitride etc.; The absorbent ring is with the netted material moulded section of stainless steel, and the oxidation absorbing material is housed in the absorbent ring.
Above-mentioned described alloy flange 21 is provided with number row circular hole, and this alloy flange adopts the coefficient of thermal expansion material close with outer tube; The effect of circular hole is to make the glass of glass outer tube two ends thickening form sealing by fusing with the alloy flange when heating soft heat state to rivet.
The preparation method of the straight-through vacuum heat collecting tube in the utility model is:
1., the annular ripple dish makes, and at first selects stainless steel, the width with ripple is being controlled between the 3.0-28.0mm then, between the crest height 2.0-20.0mm, between the material thickness 0.3-1.5mm, last punch forming, annealing.
2., to adopt material be the stainless steel material of SUS304,321,316L to metal inner pipe, caliber between 30-70mm, surperficial alignment, car, mill back are cleaned, electroplate selective absorbing film, as titanium oxide, black chromium, black cobalt, tri-iron tetroxide, alundum (Al, aluminium nitride etc.
3., the absorbent ring is with after the stainless steel netted material moulded section, enclose the oxidation absorbing material again and make.
4., with a bit of glass tubule of welding after the thermoplastic perforate on the titaniferous quartz glass outer tube.
5., 4. after titaniferous quartz glass outer tube is processed into design length in above-mentioned steps, clean, air-dry, pipe fittings outside on the termination, being inserted in (promptly with the object of glass outer tube) with material, embed the alloy flange that processes outside between pipe fittings and the glass outer tube, cover is gone up clock constant temperature electric heating plate again, after carrying out the time constant-temperature heating, the moulding internal mold will be heated to the outer tube alloy flange of soft heat state, annex pushes the outer mold forming of end moulding simultaneously, after the typing, the glass outer tube is taken out, so just with the welding of alloy flange in glass outer tube termination, use the same method again other end machine-shaping.
6., on the metal inner pipe two ends, set up ceramic ring, absorbent ring, put the glass outer tube that step is made in 5. then, put the annular ripple dish in two ends again, the outer shroud of annular ripple dish and the alloy flange of glass outer tube are welded, interior ring and metal inner pipe welding; Wherein ceramic ring have the heat that intercepts in the vacuum tube annular ripple dish by the termination to scatter and disappear and fixedly the position of outer glass pipe and interior metal tube act on; Residual air oxidation after the absorbent ring can will vacuumize absorbs.
7., the thermal-collecting tube after the moulding taken out makes vacuum, after hot melt takes off the glass tubule, eliminate the pipe navel.
8., at last internal stress is eliminated in the whole tempering of the thermal-collecting tube of machine-shaping.
