Description
Dispositivo para la eliminación de los residuos procedentes de la depuración de aguas.Device for waste disposal from water purification.
La presente invención se refiere a un dispositivo para la eliminación de los residuos procedentes de la depuración de aguas.The present invention relates to a device for the disposal of waste from the water depuration.
Para la depuración de aguas sucias (purines, alpechines, vinazas o similares) que suponen un grave problema medioambiental y que proceden de diversos usos (granjas, explotaciones agrícolas, poblaciones, industrias, etcétera) se conocen diversos sistemas y maquinarias.For the purification of dirty water (slurry, alpechines, vinasses or similar) that pose a serious problem environmental and that come from various uses (farms, farms, populations, industries, etc.) They know various systems and machinery.
Entre los mismos, una máquina para la obtención y depuración de agua contenida en residuos está escrita en la patente en 200600764. En esta máquina los residuos son prensados, microfiltrados y osmotizados, obteniendo por un lado aguas osmotizada de calidad suficiente para su vertido a un cauce natural o alcantarillado, y por otro lado un residuo sólido húmedo y un líquido de rechazo de la ósmosis con alta concentración de compuestos contaminantes ricos en nitrógeno.Among them, a machine for obtaining and purification of water contained in waste is written in the patent in 200600764. In this machine the waste is pressed, microfiltered and osmotized, obtaining water on the one hand osmotized of sufficient quality for pouring into a natural channel or sewer, and on the other hand a wet solid residue and a osmosis rejection fluid with high concentration of nitrogen-rich pollutants
Para estos restos u otros análogos procedentes de otras máquinas o tratamientos no se preveía un tratamiento capaz de eliminarlos, inconveniente que se subsana mediante el dispositivo de la invención.For these remains or other analogues from of other machines or treatments a treatment was not foreseen able to eliminate them, inconvenience that is remedied by device of the invention.
El dispositivo de la invención sirve de una manera óptima para eliminar prácticamente por completo los residuos sólidos y rechazos líquidos procedentes de diversos procedimientos y máquinas de depuración de aguas residuales, y especialmente los procedentes de la máquina protegida en la patente 200600764.The device of the invention serves as a optimal way to virtually completely eliminate waste solids and liquid rejections from various procedures and sewage treatment machines, and especially from the machine protected in patent 200600764.
De acuerdo con la invención, el dispositivo comprende una tolva de acumulación del residuo sólido dotada de una tapa y una cuba de evaporación del agua contenida en el líquido de rechazo, la cual recibe el calor producido en una cámara de combustión donde se quema el residuo sólido, alimentando la cámara de combustión preferentemente por medio de un conducto que comunica con la salida de la tolva y por cuyo interior discurre un sinfín motorizado.According to the invention, the device it comprises a solid waste accumulation hopper provided with a lid and a water evaporation tank contained in the liquid rejection, which receives the heat produced in a chamber of combustion where the solid waste is burned, feeding the chamber of combustion preferably by means of a conduit that communicates with the hopper outlet and inside which runs a motorized auger
Parte del aire y gases calientes generados en la combustión se recirculan mediante conductos y turbinas hacia la tolva para cooperar en el secado del residuo sólido, y ciertos componentes transportados en estos gases quedan retenidos en un residuo sólido, de modo que se emite al exterior fundamentalmente aire enfriado.Part of the hot air and gases generated in the combustion is recirculated through ducts and turbines to the hopper to cooperate in drying the solid residue, and certain components transported in these gases are retained in a solid residue, so that it is emitted mainly Cooled air.
Igualmente la cámara de combustión dispone de unos medios para la evacuación de las cenizas.Also the combustion chamber has means for the evacuation of ashes.
Dado que el pH previsto para el rechazo líquido será inferior a 10, se evaporará principalmente agua, quedando un pequeño resto sólido rico en compuestos de nitrógeno en forma de película, que se retirará en las labores de mantenimiento y se introducirá en la tolva para ser mezclado con lo residuos sólidos. Así, en la combustión de la mezcla estos compuestos sólidos se irán reduciendo hasta convertirse en nitrógeno con un mínimo impacto medioambiental en su emisión.Since the expected pH for liquid rejection it will be less than 10, mainly water will evaporate, leaving a small solid residue rich in nitrogen compounds in the form of film, which will be removed in maintenance work and It will be introduced into the hopper to be mixed with solid waste. Thus, in the combustion of the mixture these solid compounds will leave reducing to nitrogen with minimal impact environmental in its emission.
Las figuras 1 y 2 muestran sendas vistas lateral y en planta del dispositivo de la invención, apareciendo en la vista en planta unas secciones o roturas para mejor apreciación de los detalles.Figures 1 and 2 show side views and in plan of the device of the invention, appearing in the plan view some sections or breaks for better appreciation of the details.
El dispositivo 1 de la invención se utiliza preferentemente asociado a una máquina de depuración de aguas de diversas procedencias, no representada, tal como la descrita en la patente 200600764.The device 1 of the invention is used preferably associated with a water purification machine of various sources, not represented, as described in the 200600764 patent.
Este tipo de máquinas producen tres tipos de subproductos: agua osmotizada susceptible de ser vertida a cauces naturales o alcantarillados, residuos sólidos procedentes de una separación mecánica y microfiltrado, y un líquido concentrado de rechazo en la etapa final de ósmosis inversa. Precisamente el dispositivo de la invención está destinado a eliminar estos dos últimos subproductos.These types of machines produce three types of By-products: osmotized water that can be poured into channels natural or sewage, solid waste from a mechanical separation and microfiltration, and a concentrated liquid of rejection in the final stage of reverse osmosis. Precisely the device of the invention is intended to eliminate these two Last by-products
Para ello, el dispositivo 1 comprende una tolva 2 con tapa 3 donde se almacena el residuo sólido y una cuba 4 de evaporación donde se vierte el líquido de rechazo. Dado que el pH de este líquido es inferior a 10 se producirá fundamentalmente una evaporación de agua, generándose al cabo del tiempo una acumulación de un resto contaminante sólido, principalmente compuestos de nitrógeno, en forma de cascarilla en la cuba.For this, the device 1 comprises a hopper 2 with lid 3 where the solid waste is stored and a bowl 4 of evaporation where the rejection liquid is poured. Since the pH of this liquid is less than 10 a fundamentally evaporation of water, generating an accumulation over time of a solid pollutant moiety, mainly composed of nitrogen, in the form of husks in the tank.
Para producir la evaporación se queman en la correspondiente cámara de combustión 5 los residuos sólidos almacenados en la tolva 2, que son conducidos a la cámara de combustión por medio de un conducto 6 por donde discurre un sinfín 7 motorizado. En este ejemplo la combustión es producida por la cooperación de dos quemadores 8.To produce evaporation they burn in the corresponding combustion chamber 5 solid waste stored in hopper 2, which are led to the chamber of combustion by means of a conduit 6 through which endless 7 motorized. In this example the combustion is produced by the cooperation of two burners 8.
Los residuos sólidos deben estar exentos de humedad para poder combustionar, razón por la cual es conveniente dejarlos secar en un entorno adecuado el tiempo que se considere necesario. Aún así, como siempre van a conservar un resto humedad, el dispositivo de la invención también contempla la recirculación de parte de los gases y aire caliente procedentes de la combustión hacia la tolva a través del correspondiente conducto 9 y turbina 10 de aspiración, tras lo cual se obtiene el secado del residuo sólido y la reducción en el mismo de diversos contaminantes de los gases, emitiendo aire fundamentalmente frío. El resto de los gases y aire de la combustión se emiten a través de la correspondiente chimenea 11, de tipo ciclónico para revertir y recoger posibles partículas y evitar su emisión a la atmósfera.Solid waste must be exempt from moisture to burn, which is why it is convenient let them dry in a suitable environment for as long as considered necessary. Even so, as they will always retain moisture, the device of the invention also contemplates recirculation from the gases and hot air from combustion towards the hopper through the corresponding duct 9 and turbine 10 of aspiration, after which drying of the solid residue is obtained and the reduction therein of various gas pollutants, emitting fundamentally cold air. The rest of the gases and air of combustion are emitted through the corresponding chimney 11, cyclonic type to reverse and collect possible particles and Avoid its emission to the atmosphere.
Por su parte, las cenizas procedentes de la combustión del residuo se evacuan a través de un conducto inferior 12 con el correspondiente sinfín 13 motorizado.On the other hand, the ashes coming from the combustion of the waste is evacuated through a lower duct 12 with the corresponding motorized auger 13.
Por último, el resto sólido obtenido en forma de cascarilla en la cuba es reintroducido periódicamente en la tolva, llegando finalmente mezclado con el residuo sólido procedente de la depuración a la cámara de combustión, donde los compuestos de nitrógeno se reducen y se emite finalmente nitrógeno puro.Finally, the solid residue obtained in the form of husk in the tank is periodically reintroduced into the hopper, finally mixed with the solid residue from the purification to the combustion chamber, where the compounds of Nitrogen is reduced and pure nitrogen is finally emitted.
