EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
Así, el equipo de depuración de aguas grises que la invención propone, se puede afirmar que constituye una novedad dentro de su campo de aplicación, estando los detalles caracterizadores que lo distinguen de lo ya conocido convenientemente recogidos en las reivindicaciones finales que acompañan a la presente memoria descriptiva. Thus, the gray water purification equipment proposed by the invention can be said to be a novelty within its field of application, the characterizing details distinguishing it from what is already known conveniently included in the final claims that accompany the present descriptive memory.
De forma concreta, lo que la invención preconiza es un equipo de depuración de aguas grises que se configura, esencialmente, a partir de dos elementos distintos: por un lado un conjunto de filtrado multifuncional, formado por un filtro para evitar la entrada de sólidos gruesos en los depósitos de tratamiento, un sifón de baja altura que evita olores y permite una fácil evacuación, y una entrada de lodos bombeados periódicamente a presión en el sifón que tiene como finalidad evacuar dichos lodos al desagüe y limpiar el filtro. Specifically, what the invention advocates is a gray water purification equipment that is configured essentially from two different elements: on the one hand a multifunctional filtering assembly, formed by a filter to prevent the entry of thick solids in the treatment tanks, a low-rise siphon that avoids odors and allows for easy evacuation, and an entry of periodically pumped sludge into the siphon that is intended to evacuate said sludge to the drain and clean the filter.
Por otro lado el equipo preconizado cuenta, asimismo, un sistema inteligente de depuración biológica que integrado por, al menos, tres depósitos de tratamiento, a su vez, comprende una sonda de nivel en cada depósito, una sonda de temperatura en un primer depósito y una electrónica propia que gestiona la información de dichas sondas, y el accionamiento de unos difusores de aire previstos en el seno de cada depósito que se activan en función de la señal recibida por la electrónica para aportar el oxígeno que procure la depuración bacteriana. On the other hand, the recommended equipment also has an intelligent biological purification system that includes at least three treatment tanks, in turn, comprises a level probe in each tank, a temperature probe in a first tank and an own electronic that manages the information of said probes, and the activation of some air diffusers provided within each tank that are activated according to the signal received by the electronics to provide the oxygen that seeks bacterial clearance.
Este control inteligente se gestiona, desde la citada electrónica, con las siguientes acciones: - Control de volúmenes de aguas en los depósitos, dado que el sistema conoce permanentemente el volumen ocupado en cada depósito por la información suministrada por las sondas de nivel. Mediante esta información gestiona el funcionamiento global del proceso de depuración-clarificación-desinfección-servicio, adaptándose a la producción y demanda, acelerando o ralentizando el proceso. This intelligent control is managed, from the aforementioned electronics, with the following actions: - Control of water volumes in the tanks, since the system permanently knows the volume occupied in each deposit for the information provided by the level probes. Through this information, it manages the overall operation of the purification-clarification-disinfection-service process, adapting to the production and demand, accelerating or slowing down the process.
- Control de ciclos de depuración biológica, pues el sistema conoce permanentemente el volumen ocupado en cada depósito, por la información suministrada de las sondas, y asimismo, la información suministrada por la sonda de temperatura en el depósito del primer tratamiento biológico, permitiendo informar al sistema sobre cualquier entrada de nuevas aguas grises. Por otra parte, si se detecta un cambio de temperatura y de nivel del primer depósito, mientras se está produciendo un ciclo de depuración (aireación mediante la activación de los difusores), la electrónica evalúa si dicho cambio se debe a una pequeña o gran descarga y, en consecuencia, si puede continuar con el ciclo de depuración en curso o debe reiniciarlo. - Control of biological purification cycles, since the system permanently knows the volume occupied in each tank, by the information supplied by the probes, and also, the information supplied by the temperature probe in the tank of the first biological treatment, allowing to inform the system over any entry of new gray waters. On the other hand, if a change in temperature and level of the first tank is detected, while a purification cycle is taking place (aeration through the activation of the diffusers), the electronics assesses whether said change is due to a small or large discharge and, consequently, if you can continue with the current debug cycle or restart it.
- Optimización del consumo eléctrico del sistema de aireación, gracias a que el grupo de aportación de aire, y por tanto de oxígeno, necesario para la depuración del agua mediante lodos activos, se adapta a las necesidades de depuración reales mediante la electrónica que gestiona tanto los ciclos de depuración como la dosificación de aire en función de la cantidad generada de aguas grises y de la demanda del usuario. De este modo, se optimiza el consumo energético así como la población bacteriana responsable de la depuración, ya que se evitan situaciones como la de una sobredosificación de aire que produciría una maduración excesiva de las bacterias y, por tanto, una pérdida del poder de depuración, o como la de una aportación extra de oxígeno en agua ya depurada, totalmente innecesaria e ineficiente. - Optimization of the electrical consumption of the aeration system, thanks to the fact that the air supply group, and therefore of oxygen, necessary for the purification of water by means of active sludge, adapts to the real purification needs through the electronics that manages both Purification cycles such as air dosing based on the amount of gray water generated and user demand. In this way, energy consumption is optimized as well as the bacterial population responsible for purification, since situations such as an overdose of air that would cause excessive maturation of bacteria and, therefore, a loss of purification power are avoided , or as an extra supply of oxygen in water already purified, totally unnecessary and inefficient.
El equipo preconizado comprende, además, un sistema inteligente de suministro de agua depurada, el cual consiste en un grupo de bombeo a presión constante y caudal variable, capaz de adaptarse a todos los perfiles de equipos en el consumo doméstico, algunos (como, por ejemplo, inodoros) con una curva de llenado poco adecuada para los equipos de presión convencionales. El descrito equipo de depuración de aguas grises representa, por consiguiente, una estructura innovadora de características estructurales y constitutivas desconocidas hasta ahora para tal fin, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita. The recommended equipment also includes an intelligent system for the supply of purified water, which consists of a constant pressure and variable flow pumping group, capable of adapting to all equipment profiles in domestic consumption, some (such as for example, toilets) with a filling curve that is not suitable for conventional pressure equipment. The described gray water treatment equipment represents, therefore, an innovative structure of structural and constitutive characteristics unknown until now for this purpose, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that is requested .
