Cleaning vehicle and method for parabolic trough solar collectors
A vehicle and method for cleaning parabolic trough solar collectors (2) by means of a motorized vehicle (1) which includes a water tank (4); front (5) and rear (6) cleaning arms, with a telescopic part having several sections, coupled at one end to a pivoting head (8) which supports a rotary cleaning brush (9) and comprises spray nozzles (10), as well as proximity sensors (12) for the brushes (9). It comprises the same number of front and rear transverse guide rails (13) which include a linear movement means (14) coupled, by means of a pivot (15), to the cleaning arms (5, 6). The brushes (9) are movable in relation to the head (8) by means of a shaft (21) actuated by a retraction actuator (27) for overcoming obstacles (26).
The invention can be used to clean the entire surface of absorption tubes (10) without interfering with said tubes (10) or the structural elements (13) of the collector. The invention comprises a coupling bar (2) for coupling the device to a cleaning vehicle (12), and a chassis (1) connected to said bar (2) and including: side segments (3), an upper segment (4) and a lower segment (5), all interconnected; arms (6) that extend perpendicularly to the segments (3, 4, 5) of the chassis (1); and nozzles (7) located on the arms (6) and on the side segments (3) for spraying cleaning water onto the absorption tube (10) as the vehicle (12) is moving, such that the portion of the absorption tube (10) that is being cleaned is always confined to the space between the chassis (1) and the arms (6).
System for manufacturing facets comprising a frame a series of mirrors and multiple securing parts in which said parts are the key to the invention and are formed by a rod and a circular metal sheet provided with a series of small circular perforations, where the rod and the circular sheet are attached by electric arc welding or any other equivalent fixation and the purpose of which is to secure a curved mirror to the rear structure or frame of a heliostat.
Method for the natural-draught cooling of a high-concentration thermoelectric solar plant that includes a central receiver or tower with a heliostat field, wherein the tower is used as a natural-draught cooling tower. The steam originating from the turbine will be made to circulate through a series of condensers located at the base of the tower, where said condensers condense the steam therein and discharge the condensation heat to the atmosphere. The fluid responsible for this heat exchange is the air at ambient temperature at the base of the tower. Once condensed, the steam is pumped back towards the receiver so that it can be re-used as a heat-transfer fluid. The cooling air travels up through the tower and exits through the highest part thereof. The plant can be used to reduce not only its own electricity consumption, but also water consumption.

Superheated steam tower receiver with a well-defined configuration that benefits the transfer of heat between the surface of the component and the working fluid. Composed of at least four subpanels that define the circulation circuit for the steam by means of internal passages. The component is provided with saturated steam and for the production of said steam it is possible to use other solar concentrator technology. The proposed configuration minimizes the technological risks inherent in superheated steam receiver technology where drawbacks arise in the structure of the material owing to the thermal cycles to which the solar component is subjected.
The invention relates to a solar collector having a multi-tube receiver, to thermosolar plants that use said collector and to a method for operating said plants, where the multi-tube receivers have a primary reflector (5) formed by two continuous symmetrical parametric curves, a secondary reconcentrator (6) and a receiver (1) that includes several connected tubes (7) with a circular cross-section, the center of gravity of the collector being located very close to the axis of rotation of the collector itself, and the concentration ratio C/Cmax being greater than 0.63, having 100% collection efficiency and having a maximum of two reflections of solar rays (8). The thermosolar plants that use said multi-tube receivers combine same with cylindrical or trough collectors with a tubular receiver, and can be used for the direct generation of steam (with a saturation and overheating zone) or the indirect generation of steam (with the collectors connected in series).
