Definitions
- the present invention describes an expansion compensation device of those used in high concentration solar energy receiving tubes.
- the general principle of solar thermal technology is based on the concept of the concentration of solar radiation to produce steam, which is later used in conventional power plants.
- linear concentrators The linear concentration is easier to install with fewer degrees of freedom, but has a lower concentration factor and therefore can achieve lower temperatures than point concentration technology.
- the invention in question revolves around one of the elements that are part of said receiver tubes namely, it is the expansion compensation device.
- a receiver tube In general, a receiver tube consists of two concentric tubes between which vacuum is generated.
- the inner tube, through which the fluid that is heated circulates, is metallic and the outer tube is made of glass, usually borosilicate.
- the element described here the expansion compensating device, is placed between both tubes in a way that allows movement in the longitudinal direction of the tubes and guarantees the vacuum, absorbing the stresses that would be created by the difference between the coefficients of expansion of metal and glass.
- the compensation element of the expansion consists of a folding bellows that joins the metallic tube by a connection element and to the glass tube by a glass-metal transition element.
- Said connecting device has a series of drawbacks.
- One of them is the decrease in the performance of the system because a portion of a more or less long glass tube is covered in its interior by this bellows, so that solar radiation does not penetrate the metal tube.
- the present invention aims to devise a new compensation device that meets the requirements for this type of elements and at the same time improve its performance for products on the market.
- the invention consists in designing a new compensation device for receiver tubes that solves the deficiencies observed in the existing ones up to now.
- the new device consists of a bellows, such as those existing in the state of the art, but to which the simple wave has been replaced by a double wave also having an asymmetrical distribution of these.
- the device in this way designed, would occupy 36% less than the current which means that approximately 2% of the total length of the tube is covered and does not penetrate the sun through it, compared to 4% that is covered with the devices used Until now.
- the gain in fluid temperature would be between 0.95 and 1.2 ° C.
- Another of the modifications that has been made has been to decrease the height of the waves of the bellows passing from a height of 52.8 mm in the existing pipes to a height of 34 mm in the new development, which supposes a reduction in height of 35.6 %.
- Another of the improvements that have been studied is to vary the wave distribution of the fire.
- the wave that works the most is the second wave closest to the top and that is where a higher height is required, since it is unnecessary for all bellows waves to have the maximum height, a bellows can be manufactured that has lower the waves of the ends and higher the central waves, in this way, the diameter of the glass tube can be decreased maintaining the same properties in the connection device. This decrease in the diameter of the glass tube translates into saving of borosilicate material, lower cost in the generation of vacuum, and lower thermal losses.
- Figure 1 General view of a solar energy receiver tube
- Figure 5 Section A of figure 4
- the expansion compensating device is part of a solar energy receiving tube (1) as shown in said figure.
- These tubes (1) usually have an approximate length of about 4 meters and are located in the linear focus of a parabolic trough collector by means of supports (2) as shown in the figure, in this way, the height of the tube with respect to the ground varies with the monitoring of the collector to the sun, being located in a range of 4 to 5.5 m.
- the tube (1) is formed, generally, by a metal tube (3) through which the heat transfer fluid circulates . That tube (3) is surrounded by a glass cover (4), generally borosilicate and leaving a space with vacuum (5) between both tubes. In this space (5) the vacuum is generated to avoid heat losses.
- the expansion compensating devices (6) are placed in the form of double bellows, which are responsible for compensating the difference of coefficients of expansion between the glass (4) and the metal ( 3), allowing movements in the longitudinal direction.
- the tube ends with a piece (7) in the form of a lid.
- Figure 3 corresponds to an isometric view
- Figure 4 shows a plan view
- Figure 5 shows a section of the expansion compensating device.
- Figure 6 shows detail B of the device. Here it is verified that it is designed with a double bellows, so that the waves of the outer bellows (9) are facing the glass tube (4) and those of the inner bellows (10) to the metal tube (3).
- Figure 7 contains the detail C indicated in figure 5. It shows how the finishing of one of the ends of the device (6) is carried out.
- the manufacturing process of the expansion compensating device consists in the manufacture of two concentric bodies using the hydroforming technique.
- Basic- It is a process of shaping a material (usually a metal) by the action of a high-pressure fluid.
- the most common application consists of forming a steel tube against the walls of a matrix that has the shape of a bellows, by introducing a fluid at high pressure.
- a simultaneous axial compression can also be used to avoid excessive thinning of the tube thickness in areas subjected to a strong expansion. Both pieces thus obtained are welded by microplasma to a metallic ring of the same material to define the final assembly of the expansion compensating mechanism.
