Description

SOLAR COLLECTOR WITH SOLAR TURBINE OR TURBOCHARGER, a solar collector with a turbine for use and performance with airflows heated by solar radiation, produced by a parabolic concentrator or heliostats, has also been prepared the collector flow to various other solar turbine fuels. The turbine is powered by the flow of air received by a sensor with representation innovative with their radial ducts take the form of cone or funnel, which receives the sunlight or solar radiation depending, this, the power in kilowatts to achieve. Below fifteen kilowatts irradiation sensor will be preferably with parabolas area as the focus and thermal power depending on the power in kilowatts to produce, although it may rise to more kilowatts of production and parables greater diameter area, power above that ideally takes place, heating the air flow passing through the sensor that reaches the compressor and hot once receive the turbine motor, by a certain number of heliostats, where sensor, and others would be installed turbine tower. The turbine marks an advance over current by modifying its mechanical operation philosophy. In this turbine can be performed even when feeding fossil fuels, hydrogen or fuel of biological origin (for compounds of biomass) at the opposite outflow turbine motor, if so decided by the project which include the turbine of this patent, the ideal is that the flow is heated by solar radiation. The turbine and collector model, because of this patent occurs in three forms, one in which the external compressor is a compressor, and a model in which the compressor forms part of the turbine, but a confrontation with the turbine flow to the compressor motor, which operation will be detailed in the description of the drawings, the other is that the turbine is applied to the sensor is replaced by a turbocharger. In short, the joint is formed in and over an innovative solar collector configuration, the ducts are circular or square, which take a radial form with the establishment of a cone or funnel, and a turbine that despite saving philosophy of the thermodynamic cycle Brayton, breaks the order of components and includes a recuperated novel unlike any currently used. It is necessary to indicate that the turbine and the sensor, each independently, can work with other types of sensors and sensor elements with other thermodynamic that would fit for use, as indicated together or separate and independent. Moreover, given the novelty of the sensor and its greater efficiency, lower installations from one kilowatt to 15 kilowatts, can be installed independently turbine described in this patent, and in order to lower the resulting product, you can install a turbo kit supplying the turbine that has the distinction of being highly economical and power as a novelty attached to this type of installation with the new solar collector.

OBJECT OF THE INVENTION

The object of the invention is to improve the thermodynamic efficiency in the energy performance of the elements that make up the teams to use solar radiation as the driving force, avoid water consumption in these facilities, cheaper facilities themselves without loss efficiency, with the use of the temperature leaving the gas outlet (hot air), and with part of the energy also can produce hydrogen, or get storage means sails or oils, or high temperature fluids for use in different means to produce cold, or steam for a steam turbine advantage in the hours without solar radiation, as indicated by the inventor in his invention in the Spanish record in February 2006: U200600388, and in Europe, 07381002-0-1267 based on the priority of the previous night by feeding or other fuel.

As an important part of this patent, the object is to get the stick to avoid contamination and the production of electricity through renewable energy consumption

BACKGROUND OF THE INVENTION

As background to this invention is indicated several technologies already, all too familiar, as can be: gas turbines, steam turbines, the heliostats and the sensors used for different projects for solar thermal, steam and turbochargers. Parabolas are known for different deposits used as transmitting or receiving radiation, either one or two focus. From all this, of all different backgrounds of the technologies described, has made significant innovations and the grouping of components to achieve a precise cluster model that can improve and differentiate into everything now, and in the opinion of the inventor of this patent: a better result,

A TECHNICAL PROBLEM SOLVING

They are different problems to solve: Gas turbines are unique to pollute the environment by using fuels and a high cost for its enormous complexity, and within the possibilities thermodynamics gives low result energy efficiency. Also at these high temperatures is that the draft of this patent is try and get lessen their impact on the turbine motor and other components that set the turbine.

Another problem to solve is that the solar collectors are elements in this type of project, a very important base for the final result of the energy you get, because they depend on the need for a high capacity to receive the increased use of sunlight, and bring the heat to the fluid or flow that provides the mechanical, whether steam turbines, turbochargers, such as gas turbines or other items that require the exchange between solar radiation and these.

DESCRIPTION OF THE INVENTION

The invention is mainly composed by two elements forming one, or may be used separately; turbine or turbocharger small facilities watts, and collector, these are broken down into other components that comprise the assembly. The sensor has a radial shape but their ducts are immersed, each shadow inadvertently he continues to rotate as its center leaving each conduit in view of the solar radiation and closing each other so that the hot air that is inside cone, while it is irradiated, not leave their associations; can be transparent protective screen, or not depending on its position. All the surrounding, when radiated outside the sensor is not filled ceramic material which retains the duct temperature sensor and this material a layer of thermal insulation. Depending on the installation and its composition with the turbine, the mouth of the outer part of the sensor, the portion of greater diameter, which is presented prior to irradiation, as stated, in its inlet flow can be directed an external compressor which provides air flow to the sensor conduit which is irradiated by sunlight reflected by a parabola or heliostats, and the tubes that are directed to the output, the innermost portion or tip of the cone, where encounters a straight duct, anti turbulence with a thickness of six long duct and if necessary with fins inside to prevent rotation or tornado effect to the motor turbine inlet, corresponding to the innermost exit cone, If the set is formed with implying turbine compressor, the sensor input goes through an insulated duct to the outside, to the compressor outlet. In both cases the flow is heated by solar radiation to a greater extent on the tubes inside the cone, according enters the sensor to a temperature high at its output, flow temperature which depend on the needs of the require power in kilowatts that the turbine is installed. The sensor, in which the ducts inside are circular or square, but it can be an any way by which it can receive maximum sunlight, going with the precise mechanical assembly that it can be mounted or removed the turbine. In this case explained, the radial collector cone-shaped, the fluid can be heated interior air to the turbine in question is described in this patent, or other fluids which are required to be heated by solar radiation: water, helium, etc., for feeding another kind of mechanical generators.

The turbine is divided into several components, but mainly described the most important and your description of what use and operation: On the back, low or high, since the turbine can be placed in the position required, but giving the final entry absorbing air compressor, in the case to drive installed, it is desirable to install a filter that removes impurities from air by entering the compressor, the compressed air enters an element that comprises two sides with an intermediate portion. These faces, which we will call “A” that gives the compressor and “B” which gives the outflow of the turbine motor, are perforated. The drilling of both sides, on the outside of its circumference, are connected by tubes which unite them, and that these fine tubes is where is to flow the compressed air flow provided by the compressor, but isolated portion arises where the turbine motor flow. The tubes cover the entire outer part around the circle. Just take face holes and pipes on the outside, the inside of the circle of side A facing the interior between the two sides is blind, without any communication. The B side which faces the motor and its flow turbine has a protrusion closing the communication of the ducts leading to the compressor air flow sensor turbine. After the closure face on its inner radius B has holes that communicate air from the turbine motor flow to the interior of the two sides, A and B so that the air turbine motor to eject the high temperature passes through these holes, and on your way to the exit of these gases radiate heat that contain tubes through which the air compressor to the sensor, and these tubes to said compressed air as well as heat the blind part of the A side facing the air is compressed and gives way to the compressor and to tubes passing the air to the sensor, so that the use of hot air leaving the turbine motor is intended to be the maximum. It is important to define a system of pipes Compressed air communication with the sensor, these can be any shape as long as its inner diameter and number of ducts do not obstruct the air, the materials for side A, B and pipes that ultimately all fixed or movable mechanical part must be of an alloy having high temperatures and hold very low expansion and high resistance to corrosion by mixing the components air: oxygen, etc., with alloy mechanical components. The shaft connecting the turbine and the compressor has a sealed chamber in which the exchanger through which it is composed in side A and side B. In that part of the sealing part has a fin compressor sends a certain amount of air, a calculated amount for cooling the turbine motor that receives, attracts not, that which receives the cold air compressor and internal fins dismisses the exhaust.

Regardless of the multi-piece sensor that is broken and turbine, which join four main components: compressor chamber which is joined to the intermediate heat exchanger does serve as hot gas output. The heat exchanger is attached to the turbine chamber covering motor, the motor chamber which is attached to the sensor and the latter. The kinetic motion generated by the motor moves the turbine compressor, and the same axis moves the current generator. In the case of using the turbocharger, the description using the turbine can be adapted similarly to the turbocharger.

In the event that the compressor is outside screw type or whatever, the turbine motor is directly transmuted to the generator work without intermediate compressor. In this case will the two heat exchangers to heat the working fluid, one is located at the exit of gases, and the other in communication therewith, the air inlet of the solar collector as described above, air that becoming compressor external. In all described, solar radiation sensor, may be through parabolic troughs or minors, as well as the installation of components: sensor, or turbo-charger turbine, compressor and generator can be installed on tower or parable.

DESCRIPTION OF A PREFERRED EMBODIMENT

A preferred embodiment in the case of this double project (embedded or external compressor to the turbine shaft, with parabola, or tower) may be two: installed in a solar tower of sufficient height where the radiation heliostats in its projection not overshadow, or small-scale, with the collector to focus irradiation of a parabola. In the first case is required to perform a civil work at a certain height to house a platform for supporting generator, turbine and sensor. The sensor has to be done with tubes of a few millimeters of material section and either square or circular, high thermal transmissibility and high thermal resistance at high temperatures and that has the lowest expansion alloy, all to have the better transmission of heat from solar radiation where the material will circulate fluid: in this project the fluid is air, and to form a radial shape with a spiral conformation of its cone shape, where each turn is behind, but in view of the radiation and decreasing the diameter of each turn until the outflow where the output would be coupled to the turbine inlet conduit and another motor would be input to the sensor, in the first round, that is to communicate with the compressor outlet. The cone will have a tilt sensor in which the radial portion is directed towards the heliostat so that the highest point of solar incidence is the last round that matches the turbine sensor communication. This will make the first round outer radial sensor reaches a high temperature, and that increases in each round as it approaches the exit where shrinks and where temperatures can reach up to 1200° C. When the turbine sensor join up either a turbocharger or supercharger this turbine will be as stated in the description of the invention: ready to receive air flow heated by solar radiation and with the compressed air duct to be connected to the input of the sensor, if any incorporates the compressor turbine in the case of the turbocharger the compressor is implied herein. The gas output goes directly to the exit of the tower that supports the plant, which in principle would ideally it was hollow so that the hot gases, clean air, originate, rising temperature differential, air circulation will cool all its components. At the outlet of the turbine motor, after passing the air between the tubes through which the compressed airflow from the compressor to the sensor, in order to exploit waste hot air, it will be used to be used by heat exchangers air/fluid oils, salts etc. to store or produce, in situ, to produce heat energy in the hours of sunlight no or generate hydrogen by steam and use some of the electricity generated in the nigh peaks of solar isolation in which the energy provided by the sun is high. The irradiation will by heliostats, for tower installation, preferably those which can give focus individually.

Another preferred embodiment is using the same components as In the installation of the tower, is at a much smaller scale in which the elements will be installed in a parabola in which the sensor will be in the focal point of increased incidence of solar radiation and after him the mini turbine and generator DC or AC. Given the size, the diameter of a parabola, which is required for more than 15 kW, although can reach other sizes, we advise that preferably more suitable facility is preferred tower, when the electric power is required to exceed fifteen kilowatts commented.
