REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
A continuación, y de manera detallada, se procederá a describir la instalación y el procedimiento de transformación de residuos orgánicos de la presente invención. Next, and in detail, we will proceed to describe the installation and the process of transformation of organic waste of the present invention.
La instalación de transformación de residuos orgánicos comprende: The organic waste transformation facility includes:
unos medios de alimentación (1) de los residuos orgánicos. feeding means (1) for organic waste.
• una unidad de cogeneración (5) configurada para generar aire caliente y electricidad para la alimentación de la instalación y/o su derivación a una red de consumo, donde la unidad de cogeneración comprende una turbina de gas (6) y un generador eléctrico (7); • a cogeneration unit (5) configured to generate hot air and electricity to supply the installation and / or its derivation to a consumption network, where the cogeneration unit comprises a gas turbine (6) and an electric generator ( 7);
• un reactor (4) configurado para llevar a cabo una pirólisis y opcionalmente una gasificación de ios residuos orgánicos, donde el reactor (4) comprende un conjunto de muflas (2, 3) que a su vez comprende un primer subconjunto de muflas (2) y un segundo subconjunto de muflas (3); • a reactor (4) configured to carry out a pyrolysis and optionally a gasification of the organic waste, where the reactor (4) comprises a set of muffles (2, 3) which in turn comprises a first subset of muffles (2 ) and a second subset of muffles (3);
• una refinería (11) configurada para llevar a cabo una condensación fragmentada de los residuos orgánicos y de esta manera obtener productos útiles para la industria. • a refinery (11) configured to carry out a fragmented condensation of organic waste and thus obtain useful products for industry.
A través de los medios de alimentación (1), que preferentemente son una cinta transportadora, se carga el primer subconjunto (2) de muflas (2, 3) del reactor (4). Se pone en marcha la turbina de gas (6) de la unidad de cogeneración (5) para generar aire caliente, entre 500° y 800° C, que se conduce ai reactor (4) por un primer conducto (9) a partir de un extremo inferior (8) de dicho reactor (4). El aire residual de salida se canaliza a través de un sifón (10) dispuesto a la salida del reactor (4), configurado para canalizar el aire residual a la salida del reactor (4) y enviarlo a la refinería (11), donde el sifón comprende un serpentín intercambiador de calor (12) para aprovechar el calor residual en la refinería (11) y producir vapor antes de soltar el aire residual a la atmosfera Through the feeding means (1), which are preferably a conveyor belt, the first subset (2) of muffles (2, 3) is loaded from the reactor (4). The gas turbine (6) of the cogeneration unit (5) is started to generate hot air, between 500 ° and 800 ° C, which is led to the reactor (4) through a first duct (9) from a lower end (8) of said reactor (4). The outlet residual air is channeled through a siphon (10) arranged at the outlet of the reactor (4), configured to channel the residual air at the outlet of the reactor (4) and send it to the refinery (11), where the siphon it comprises a heat exchanger coil (12) to take advantage of the residual heat in the refinery (11) and produce steam before releasing the residual air into the atmosphere
En el interior del reactor (4) se calienta el primer subconjunto (2) de muflas (2, 3) durante 3-6 horas para producir la pirólisis de los residuos orgánicos dispuestos en el interior del primer subconjunto (2) de muflas (2, 3), hasta que queda en su interior la parte carbonosa (solida) de ios residuos orgánicos y se extraen ios gases que se conducen a la refinería (11) mediante la apertura del primer subconjunto (101) del primer conjunto (101 , 102) de válvulas configuradas para permitir/cerrar el paso de los gases de salida provenientes del reactor (4) para su entrada en la refinería (11) La duración de la etapa pirólisis viene determinada por un sensor óptico que determina la relentización de la salida de gas. Es entonces cuando se acciona una bomba de vacío para acelerar y extraer la totalidad de los gases residuales en las muflas. Transcurridos unos minutos, el sensor óptico determinará el final de la etapa de pirólisis. Inside the reactor (4) the first subset (2) of muffles (2, 3) is heated for 3-6 hours to produce the pyrolysis of the organic residues disposed inside the first subset (2) of muffles (2 , 3), until the carbonaceous (solid) part of the organic waste remains inside and the gases are extracted that are led to the refinery (11) by opening the first subset (101) of the first set (101, 102 ) of valves configured to allow / close the passage of exhaust gases from the reactor (4) for entry into the refinery (11) The duration of the pyrolysis stage is determined by an optical sensor that determines the slowdown of the output of gas. It is then when a vacuum pump is activated to accelerate and extract all the residual gases in the muffles. After a few minutes, the optical sensor will determine the end of the pyrolysis stage.
Cuando ha finalizado el paso de los gases de salida provenientes del reactor (4) para su entrada en la refinería (11) se cierra el primer subconjunto (101) de! primer conjunto (101 , 102) de válvulas y se procede al llenado del segundo subconjunto (3) de muflas (2, 3) que estaban vacías con residuos orgánicos procedentes de la cinta transportadora, se abre el primer subconjunto (111) del segundo conjunto de válvulas (111 , 112) configuradas para permitir/cerrar el paso de aire atmosférico enriquecido con oxígeno al interior del reactor (4) una vez que se ha llevado a cabo la pirólisis en el reactor (4) concretamente ai segundo subconjunto (3) de muflas (2, 3), que contienen el residuo carbonoso, y simultáneamente se abre el primer subconjunto (121) del tercer conjunto de válvulas (121 , 122) configuradas para permitir/cerrar el paso de unos gases de salida y condensados provenientes del reactor (4) para su entrada en la refinería (11) When the passage of the exhaust gases from the reactor (4) for its entry into the refinery (11) has finished, the first subset (101) of! first set (101, 102) of valves and the second subset (3) of muffles (2, 3) that were empty with organic residues from the conveyor belt is filled, the first subset (111) of the second set is opened of valves (111, 112) configured to allow / close the passage of atmospheric air enriched with oxygen to the interior of the reactor (4) once the pyrolysis has been carried out in the reactor (4) specifically to the second subset (3) of muffles (2, 3), containing the carbonaceous residue, and simultaneously the first subset (121) of the third set of valves (121, 122) configured to allow / close the passage of some exhaust gases and condensates from the reactor (4) for entering the refinery (11)
Este proceso se lleva a cabo de manera alterna para el primer (2) y segundo subconjunto (3) de muflas (2, 3) y sus correspondientes válvulas (101 , 102, 111 , 112, 121 , 122), tal y como está representado en la Figura 7. This process is carried out alternately for the first (2) and second subset (3) of muffles (2, 3) and their corresponding valves (101, 102, 111, 112, 121, 122), as is represented in Figure 7.
Al entrar en contacto el aire atmosférico con la parte carbonas del Interior de las muflas (2, 3), se produce la ignición espontánea de la parte carbonosa residual y se produce una reacción exotérmica. Este calor sumado al calor que produce la turbina de gas (6) produce la pirólisis en las muflas (2, 3) que se acaban de cargar con residuos orgánicos. De la reacción exotérmica de la parte carbonosa, además de producir calor, se producen gases (CO) que se canalizan a través del tercer conjunto de válvulas (121 , 122) de salida a un quemador de la turbina de gas (6) para contribuir a su alimentación. Esta es la etapa de gasificación. Dicha etapa de gasificación no tendría ningún problema si el carbón fuese de origen vegetal, ya que con la etapa de pirólisis se consigue extraer todos los productos orgánicos, pero no los inorgánicos. La propia naturaleza del carbono tiene la propiedad de absorber contaminantes de los productos que deben pasar por la etapa de gasificación. A parte del carbón, existen contaminantes como el azufre, plásticos tipo PVC que contienen gran cantidad de doro y otros residuos plásticos contienen cargas de sílice para darles rigidez. Los residuos de RSU (Residuos Sólidos Urbanos) contienen todo tipo de metales pesados, clorhídricos, y otros contaminantes. When the atmospheric air comes into contact with the carbon part of the Interior of the muffles (2, 3), spontaneous ignition of the residual carbonaceous part occurs and an exothermic reaction occurs. This heat added to the heat produced by the gas turbine (6) produces pyrolysis in the muffles (2, 3) that have just been loaded with organic waste. From the exothermic reaction of the carbonaceous part, in addition to producing heat, gases (CO) are produced that are channeled through the third set of outlet valves (121, 122) to a gas turbine burner (6) to contribute to your diet. This is the gasification stage. Said gasification stage would not have any problem if the coal were of vegetable origin, since with the pyrolysis stage it is possible to extract all organic products, but not inorganic ones. The very nature of carbon has the property of absorbing contaminants from products that must go through the gasification stage. Besides coal, there are pollutants such as sulfur, PVC-type plastics that contain a large amount of doro, and other plastic residues that contain silica fillers to make them stiff. RSU (Urban Solid Waste) wastes contain all kinds of heavy metals, hydrochloric, and other contaminants.
Para separar este tipo de residuos inorgánicos, ¡a refinaría (1 1) comprende un conjunto de destiladores (25) para separarlos del CO antes de enviarlos a la turbina (6). To separate this type of inorganic waste, the refinery (1 1) comprises a set of distillers (25) to separate them from the CO before sending them to the turbine (6).
El objetivo de la instalación y el procedimiento asociado es producir un gas CO limpio, para que no se produzcan daños al quemarlos en la turbina de gas (6) y poder agrupar individualmente los productos obtenidos para darles salida comercial. Para ello se conduce el gas CO y ios contaminantes a la refinería (11), teniendo en cuenta que el volumen de gases a tratar es sensiblemente inferior a los gases tratados en la etapa de pirólisis. The objective of the installation and the associated procedure is to produce a clean CO gas, so that no damage occurs when burned in the gas turbine (6) and to be able to individually group the products obtained to give them commercial outlet. For this, the CO gas and the pollutants are taken to the refinery (11), taking into account that the volume of gases to be treated is significantly less than the gases treated in the pyrolysis stage.
Por tanto, en el procedimiento en el primer subconjunto (2) de muflas (2, 3) se lleva a cabo la etapa de pirólisis y en el segundo subconjunto (3) de muflas (2, 3) se produce la etapa de gasificación que cede calor dentro del reactor (4) para contribuir a ia etapa de pirólisis. Este ciclo se repite continuamente y alternativamente. Therefore, in the procedure in the first subset (2) of muffles (2, 3) the pyrolysis step is carried out and in the second subset (3) of muffles (2, 3) the gasification step occurs which Heat is transferred into the reactor (4) to contribute to the pyrolysis stage. This cycle is repeated continuously and alternately.
Finalmente en la refinería (11) se nutre de los gases de ia etapa de pirólisis. Se produce ia condensación fragmentada mediante un conjunto de condensadores (15) configurados para llevar a cabo una condensación fragmentada de los residuos orgánicos. La refinería (11) comprende además un condensador muiti-tubo inclinado (16) configurado para extraer el 100% de los productos condensables de los gases de salida provenientes del reactor (4), preferentemente por decantación. Después de ios condensadores (15) tan solo queda un gas de alta pureza que contribuye a la alimentación de la turbina de gas (6). La refinería comprende una columna rectificadora (17) configurada para obtener hidrocarburos como queroseno, gasolina, gas-oil, aceite ligero, aceite denso, a partir de los gases de salida provenientes del reactor (4), que tienen una densidad máxima ai 0,98. Finally, in the refinery (11) it is fed by the gases from the pyrolysis stage. Fragmented condensation occurs through a set of condensers (15) configured to carry out fragmented condensation of organic waste. The refinery (11) also includes a muiti-inclined tube condenser (16) configured to extract 100% of the condensable products from the exhaust gases from the reactor (4), preferably by decantation. After the condensers (15) only a high purity gas remains which contributes to the supply of the gas turbine (6). The refinery comprises a rectifying column (17) configured to obtain hydrocarbons such as kerosene, gasoline, gas oil, light oil, dense oil, from the exhaust gases from the reactor (4), which have a maximum density of ai 0, 98.
En función del residuo tratado, se obtienen unas materias primas u otras: parafinas y sus refinados, hidrocarburos, aceites... Cuando se trata de residuos de madera, se obtienen ácidos piroleñosos que se utilizan como conservantes, barnices, etc. Depending on the treated waste, some raw materials or others are obtained: paraffins and their refined products, hydrocarbons, oils ... When it comes to wood waste, pyroleinous acids are obtained that are used as preservatives, varnishes, etc.
En la entrada de aire atmosférico a las muflas donde se va a producir la gasificación del residuo carbonoso, se inyecta vapor de agua con el objeto de regular la temperatura a la vez que se enriquece la salida de ios gases con hidrógeno. Este vapor de agua se obtiene haciendo pasar un serpentín por el intercambiador de calor (12) del aire residual de la salida del reactor (4). Todos los gases procedentes de la etapa de gasificación tienen una procedencia inorgánica y hay que depurarlos. Gradas a que los contaminantes tienen una densidad muy por encima de 1 son relativamente fáciles de separar del gas CO + HzO, que es el que se produce en la etapa degasificación. Una vez depurados los gases ya se pueden enviar el gas CO + H2O a ¡a turbina de gas (6) para contribuir a la alimentación del reactor (4). At the entrance of atmospheric air to the muffles where the gasification of the carbonaceous residue is going to take place, steam is injected in order to regulate the temperature while enriching the exit of the gases with hydrogen. This water vapor is obtained by passing a coil through the heat exchanger (12) of the residual air at the outlet of the reactor (4). All gases from the gasification stage have an inorganic origin and must be purified. Because the pollutants have a density well above 1, they are relatively easy to separate from the CO + HzO gas, which is produced in the gasification stage. Once the gases have been purified, the CO + H2O gas can be sent to the gas turbine (6) to help feed the reactor (4).
El reactor (4) dispone de un sensor de temperatura para regular la potencia de la turbina de gas (6). The reactor (4) has a temperature sensor to regulate the power of the gas turbine (6).
Las culatas (20) de las muflas (2, 3) son herméticas gracias a la disposición de un cierre cónico (21), una junta textil (22) (liconel), una junta tórica (23) y una junta refrigerada por agua (24). The cylinder heads (20) of the muffles (2, 3) are hermetic thanks to the provision of a conical seal (21), a textile seal (22) (liconel), an O-ring (23) and a water-cooled seal ( 24).
