Descrizione tecnica dell'invenzione industriale dal titolo: Technical description of the industrial invention entitled:
Procedimento per la separazione di fluidi bi-fase e relativo impianto acceleratore Process for the separation of two-phase fluids and related accelerator system
Forma oggetto del presente trovato un procedimento per la separazione per fluidi bi-fase ed il relativo impianto acceleratore. Sono noti, allo stato della tecnica, diversi sistemi di separazione di fluidi bi-fase, i quali si basano sui seguenti principi, impiegati del tutto o in parte, a seconda della tipologia di impianto: il principio di coalescenza che induce, appunto, il fenomeno di coalescenza nelle particelle di fluido disperso, tramite filtri coalescenti o batterie di canalizzazione del flusso; il principio di separazione che induce nel fluido bifase un regime di moto laminare al fine di annullare i vettori di forza propri di un regime di moto turbolento, nonché una separazione fìsica naturale dei due fluidi, con velocità proporzionale alla loro differenza di densità; infine, il principio dì estrazione del fluido disperso che separa il fluido a densità minore tramite impiego di skimmer o per tracimazione, sempre in regime di moto laminare. The present invention relates to a process for the separation for two-phase fluids and the relative accelerator system. In the state of the art, different systems of separation of two-phase fluids are known, which are based on the following principles, used in whole or in part, depending on the type of plant: the principle of coalescence which induces, in fact, the coalescence phenomenon in the dispersed fluid particles, through coalescing filters or flow channeling batteries; the principle of separation which induces a laminar motion regime in the two-phase fluid in order to cancel the force vectors of a turbulent motion regime, as well as a natural physical separation of the two fluids, with a speed proportional to their density difference; finally, the principle of extraction of the dispersed fluid which separates the fluid with a lower density through the use of skimmers or by overflow, always in a laminar motion regime.
Il grosso svantaggio dei sistemi noti è costituito dal fatto che nessuno di essi è in grado di accelerare il processo di separazione del fluido bifase. Inoltre, i sistemi di cui sopra, presentano tutti forti limiti legati ai seguenti aspetti negativi: • limitazione della portata di fluido da trattare; la mancanza del principio di accelerazione del fenomeno di separazione comporta la necessità di limitare le portate trattate al fine di consentire un regime laminare al fluido, indispensabile alla separazione dei due fluidi; The big disadvantage of the known systems is constituted by the fact that none of them is capable of accelerating the process of separating the two-phase fluid. Furthermore, the above systems all have severe limitations linked to the following negative aspects: • limitation of the flow rate of fluid to be treated; the lack of the principle of acceleration of the separation phenomenon entails the need to limit the flow rates treated in order to allow a laminar regime to the fluid, which is essential for the separation of the two fluids;
• grado di contaminazione del residuo molto elevato; i livelli di contaminazione residua dei fluido trattato non scendono al disotto di qualche punto percentuale; • very high degree of contamination of the residue; the residual contamination levels of the treated fluid do not drop below a few percentage points;
• irreversibilità del sistema; a causa dei limiti propri dei principi fisici su cui si basano, i sistemi sopra descritti non sono in grado di separare fluidi bifase, con concentrazione del fluido a densità minore superiore al 50%; • irreversibility of the system; due to the limits of the physical principles on which they are based, the systems described above are not able to separate two-phase fluids, with a fluid concentration of less than 50% density;
• ingombri elevati; al fine di consentire lo stato di quiete del fluido, al crescere delle portate da trattare aumenta proporzionalmente il fabbisogno di volume necessario a portare il fluido in stato di quiete; analogamente il fenomeno di separazione fìsica dei due fluidi, in mancanza di accelerazione dello stesso, richiede lunghi tempi di decantazione dei fluidi; • large dimensions; in order to allow the quiescent state of the fluid, as the flow rates to be treated increase, the volume requirement necessary to bring the fluid to a quiescent state increases proportionally; similarly, the phenomenon of physical separation of the two fluids, in the absence of acceleration of the same, requires long decanting times of the fluids;
• bassa efficienza del processo di separazione; nessuno dei sistemi sopra descritti è in grado di intercettare particelle di fluido disperso in moto turbolento, in quanto non presenti sulla superfìcie di prelievo del fluido da trattare; • low efficiency of the separation process; none of the systems described above is capable of intercepting particles of dispersed fluid in turbulent motion, since they are not present on the withdrawal surface of the fluid to be treated;
♦ condizioni di impiego fortemente limitate; al fine di garantire il verificarsi dei prìncipi fisici su cui si basano, i sistemi sopra descritti sono impiegabili esclusivamente in applicazioni statiche. ♦ severely limited conditions of use; in order to guarantee the occurrence of the physical principles on which they are based, the systems described above can only be used in static applications.
Il trovato oggetto della presente invenzione risolve I problemi tecnici sopra menzionati in quanto trattasi di un procedimento per la separazione di fluidi bi-fase e de! relativo impianto acceleratore. Quest’ultimo comprende mezzi per la spinta del fluido bifase, almeno una vasca di lavaggio, mezzi filtranti per la coalescenza delle particelle, sensori e attuatori per il controllo di portata, pressione e temperatura, almeno un serbatoio per la raccolta del fluido a densità minore (normalmente olio) ed è caratterizzato da un separatore dell’olio in grado di generare un campo di pressioni idrodinamiche controllato, correlato alla densità dei fluidi da trattare, al fine di accelerare il fenomeno di coalescenza delle particelle residue. Tale campo di pressioni accelera il fenomeno di stratificazione, consentendo lo spillamento della fase a densità minore (ad esempio, olio) e il flusso costante della fase decontaminata (ad esempio, acqua) verso l’uscita dal sistema. The invention object of the present invention solves the technical problems mentioned above since it is a process for the separation of bi-phase and de-phase fluids. related accelerator system. The latter includes means for pushing the two-phase fluid, at least one washing tank, filtering means for coalescing the particles, sensors and actuators for controlling the flow rate, pressure and temperature, at least one tank for collecting the lower density fluid (normally oil) and is characterized by an oil separator capable of generating a controlled hydrodynamic pressure range, correlated to the density of the fluids to be treated, in order to accelerate the coalescence phenomenon of residual particles. This pressure range accelerates the stratification phenomenon, allowing the tapping of the lower density phase (for example, oil) and the constant flow of the decontaminated phase (for example, water) towards the exit from the system.
Scopo del trovato è dunque assolvere il compito di accelerare la separazione di due fluidi non miscibili, a densità diversa, in regime di moto turbolento. The aim of the invention is therefore to accomplish the task of accelerating the separation of two immiscible fluids, having different densities, in a turbulent flow regime.
Secondo un ulteriore scopo, il trovato è reversibile, in quanto consente la separazione della fase dispersa, senza limiti di concentrazione nella fase continua. According to a further object, the invention is reversible, since it allows the separation of the dispersed phase, without concentration limits in the continuous phase.
Questi ed altri vantaggi appariranno nel corso della descrizione dettagliata dell’invenzione che farà riferimento specifico alla tavola 1/1 nella quale sì rappresenta un esempio di realizzazione preferenziale dell’impianto e dello schema dì processo assolutamente non limitativo. These and other advantages will appear in the course of the detailed description of the invention which will refer specifically to table 1/1 in which it represents an example of preferential implementation of the plant and of the absolutely non-limiting process scheme.
L’impianto ed il relativo processo sono idonei per la separazione delle fasi di qualsiasi fluido bi-fase, caratterizzato da fasi a differente densità. Con riferimento alla fìg. 1 rimpianto in oggetto comprende un primo mezzo di spinta ( 1) del fluido bifase, almeno una vasca di lavaggio (2), un secondo mezzo di spinta del fluido (3), mezzi filtranti per la coalescenza delle particelle (4), (5) a diverso potere filtrante, un separatore di fase (6) che costituisce il cuore del sistema, almeno un serbatoio per la raccolta del fluido a densità minore (7), un sistema di analisi della decontaminazione della fase residua (8), sensori e attuatori per il controllo di portata, pressione e temperatura. The plant and its process are suitable for the separation of the phases of any two-phase fluid, characterized by phases with different densities. With reference to fig. The regret in question comprises a first means for pushing the two-phase fluid (1), at least one washing tank (2), a second pushing means for the fluid (3), filtering means for the coalescence of the particles (4), (5 ) with different filtering power, a phase separator (6) which constitutes the heart of the system, at least a tank for the collection of the fluid with a lower density (7), a system for analyzing the decontamination of the residual phase (8), sensors and actuators for flow, pressure and temperature control.
Al fluido bi-fase da separare è, dunque, conferita l’energia meccanica necessaria a bilanciare le perdite di carico proprie del sistema dai mezzi di spinta (1 ), (3). Nel fluido disperso, in moto turbolento, si induce un primo fenomeno di variazione dimensionale delle particelle tramite coalescenza forzata nelle batterie filtranti (4), (5), al fine di facilitare il processo dì separazione. La spinta idrostatica agente sulle particelle, contrastata dai vettori di forza indotti dal regime di moto browniano generato dalla turbolenza del fluido, consente di ottenere una prima separazione delle due fasi. The two-phase fluid to be separated is, therefore, given the mechanical energy necessary to balance the pressure losses of the system by the thrust means (1), (3). In the dispersed fluid, in turbulent motion, a first phenomenon of dimensional variation of the particles is induced by forced coalescence in the filter batteries (4), (5), in order to facilitate the separation process. The hydrostatic thrust acting on the particles, contrasted by the force vectors induced by the Brownian motion regime generated by the turbulence of the fluid, allows to obtain a first separation of the two phases.
il fluido è successivamente canalizzato meccanicamente, tramite diffusori tarati, in grado di generare un moto laminare e contemporaneamente la stratificazione delle due fasi. Nel separatore di fase (6), a valle dei diffusori, è generato un campo di pressioni idrodinamiche controllato, correlato alla densità dei fluidi da trattare, al fine di accelerare il fenomeno di coalescenza delle particelle residue. Tale campo di pressioni accelera il fenomeno di stratificazione, consentendo lo spillamento della fase a densità minore (ad esempio, olio) verso il serbatoio di raccolta (7) ed il flusso costante della fase decontaminata (ad esempio, acqua) verso l’uscita dal sistema. L’analisi della decontaminazione è possibile nel sistema (8) e normalmente il livello di inquinante residuo è dell’ordine di qualche ppm. the fluid is then mechanically channeled, through calibrated diffusers, capable of generating a laminar motion and simultaneously the stratification of the two phases. In the phase separator (6), downstream of the diffusers, a controlled hydrodynamic pressure field is generated, correlated to the density of the fluids to be treated, in order to accelerate the coalescence phenomenon of the residual particles. This pressure field accelerates the stratification phenomenon, allowing the tapping of the lower density phase (for example, oil) towards the collection tank (7) and the constant flow of the decontaminated phase (for example, water) towards the exit from the system. The decontamination analysis is possible in the system (8) and normally the residual pollutant level is of the order of a few ppm.
L’acceleratore di separazione fluido bifase si presenta quindi come sistema ideale per la separazione di due fluidi a densità diversa, in un vasto campo applicativo e senza restrizioni di alcun tipo inerenti i fluidi, le portate, le temperature, il regime di moto e le caratteristiche del luogo di impiego. E indicato per applicazioni nei seguenti settori: metalmeccanico, siderurgico, petrolifero, alimentare, navale, aeronautico, ecologia terrestre, ecologia marittima, chimico. The two-phase fluid separation accelerator is therefore the ideal system for the separation of two fluids with different densities, in a vast field of application and without restrictions of any kind concerning fluids, flow rates, temperatures, motion regime and characteristics of the place of use. It is suitable for applications in the following sectors: engineering, steel, oil, food, naval, aeronautics, terrestrial ecology, maritime ecology, chemical.
