DESCRIZIONE DI INVENZIONE INDUSTRIALE DESCRIPTION OF INDUSTRIAL INVENTION
AVENTE PER TITOLO: AERATORE MULTIPLO PRESSURIZZATO ?AMP? HAVING THE TITLE: MULTIPLE PRESSURIZED AERATOR? AMP?
RELAZIONE SUL SISTEMA DI AERAZIONE "AERATORE MULTIPLO PRESSURIZZATO AMP" REPORT ON THE "AMP PRESSURIZED MULTIPLE AERATOR" AERATION SYSTEM
Il sistema cos? come denominato provvede all'ossigenazione all?interno delle vasche di contenimento liquami a profondit? variabili da 3 fino a 10-15 metri. The system cos? as named, it provides oxygenation inside the slurry containment tanks at depth? variable from 3 up to 10-15 meters.
E? necessario provvedere ad un accorgimento funzionale che permetta di intervenire sul funzionamento del sistema di insufflazione in modo semplice, rapido e modulato che possa tener conto di variabili quali: AND? It is necessary to provide a functional device that allows to intervene on the operation of the insufflation system in a simple, rapid and modulated way that can take into account variables such as:
- la profondit? di immersione - the depth? of immersion
- la distribuzione delle bolle d'aria miscelata con il liquame - the distribution of air bubbles mixed with the sewage
- la velocit? di ossigenazione del fango misurata con ossimetro (redox) - the speed? oxygenation of the sludge measured with an oximeter (redox)
- la differenza di pressione di espulsione della miscela aria-acqua misurata tra la distanza degli ugelli vicini alla bocca dell'elettropompa e quelli pi? lontani, distribuiti su tutto il fronte di insufflaggio. - the difference in expulsion pressure of the air-water mixture measured between the distance of the nozzles near the mouth of the electropump and those more? distant, distributed over the whole blowing front.
Tutte queste variabili, dopo diversi studi e prove sperimentali, hanno portato alla necessit? di applicazione di ugelli intercambiabili, distribuiti sul fronte di insufflaggio che potessero interagire con comodit? di applicazione e di impiego portando alla soluzione delle seguenti fasi: All these variables, after several studies and experimental tests, have led to the need? of application of interchangeable nozzles, distributed on the blowing front that could interact with comfort? of application and use leading to the solution of the following phases:
- sostituzione degli ugelli in caso di usura dovuta all'abrasione di esercizio - scelta del calibro dei fori di uscita ugelli adattandoli alle specifiche esigenze di insufflaggio - replacement of the nozzles in case of wear due to abrasion during operation - choice of the caliber of the nozzle outlet holes, adapting them to the specific blowing needs
- scelta sulla distanza del diverso calibro dei fori degli ugelli, posizionati sullo stesso fronte di insufflaggio. - choice on the distance of the different caliber of the nozzle holes, positioned on the same blowing front.
Dette operazioni semplici, ma estremamente risolutive di molti problemi tecnici essenziali, possono essere eseguite quindi, bilanciando il sistema ai diversi casi grazie all?uso di ugelli intercambiabili. Come dimostrano i disegni tecnici allegati (Tavole 3-4) i due corpi smontabili del sistema rendono solidali gli ugelli al fronte di insufflaggio stringendoli e sigillandoli tra due guarnizioni poste fronte-retro degli ugelli. La parte anteriore del corpo ?AMP" e quella posteriore fa inoltre da camera di diffusione della miscela aria-acqua da iniettare in vasca violentemente, col compito di tenere in agitazione l'intera massa liquida contenuta e nel contempo ossigenandola. These simple operations, but extremely resolving of many essential technical problems, can therefore be performed, balancing the system to the different cases thanks to the use of interchangeable nozzles. As shown in the attached technical drawings (Tables 3-4), the two removable bodies of the system make the nozzles integral with the blowing front by tightening and sealing them between two gaskets placed front-back of the nozzles. The front part of the? AMP "body and the rear part also act as a diffusion chamber for the air-water mixture to be injected violently into the tank, with the task of keeping the entire liquid mass in agitation and at the same time oxygenating it.
L'utilit? del sistema di ossigenazione descritto deve sempre essere correlata alla possibilit? di avere nella sospensione dei reflui residui di filtrazione, quali farine fossili, perliti o sabbie, che provocano usura precoce della girante e che possono compromettere velocemente il sistema autoaspirante del sistema ad eiettore. Per questo in SER.ECO. sono state condotte prove su un sistema ideato e realizzato sperimentalmente atto a funzionare sia ad aria che ad ossigeno puro, utilizzando degli ugelli diffusori differenziabili a seconda delle particolari esigenze del refluo in depurazione e sostituibili all'occorrenza a costi irrilevanti. The utility of the described oxygenation system must always be related to the possibility? to have filtration residues in the suspension of the wastewater, such as diatomaceous earth, pearlite or sand, which cause premature wear of the impeller and which can quickly compromise the self-suction system of the ejector system. For this reason in SER.ECO. Tests were carried out on a system designed and developed experimentally designed to operate with both air and pure oxygen, using diffuser nozzles which can be differentiated according to the particular needs of the wastewater being treated and which can be replaced if necessary at irrelevant costs.
L?aeratore ?AMP" (cos? chiamato da SER.ECO.) ? costituito quindi da una camera di distribuzione scomponibile, composta da: The aerator? AMP "(so called by SER.ECO.) Is therefore made up of a dismountable distribution chamber, consisting of:
un corpo diffusore dove principalmente avviene la miscelazione aria-refluo, qui l?aria viene insufflata a bassa pressione da una soffiante immersa; un segmento di raccordo con la camera di miscelazione; a diffuser body where the air-wastewater mixing mainly takes place, here the air is blown in at low pressure by an immersed blower; a connecting segment with the mixing chamber;
un numero variabile di ugelli, diversif?cabili tra loro. a variable number of nozzles, diversifiable from each other.
La camera di miscelazione ? studiata in modo tale da ripartire uniformemente l?aria del fluido pompato. The mixing chamber? designed in such a way as to uniformly distribute the air of the pumped fluid.
Il liquido ? pompato ad alta velocit?; il gas ? fornito a bassa pressione. The liquid? pumped at high speed; the gas ? supplied at low pressure.
Il contatto tra i due flussi avviene in modo tale da creare una prima fortissima miscelazione aria - refluo con la rottura dell'aria in bolle fini. The contact between the two flows occurs in such a way as to create a first very strong air - waste mixture with the breaking of the air into fine bubbles.
La miscela cos? ottenuta prima di essere immessa nella vasca ? costretta al passaggio attraverso un numero variabile di ugelli inseriti in apposite camere di miscelazione che accentueranno ulteriormente la miscelazione. The mixture so? obtained before being placed in the tank? forced to pass through a variable number of nozzles inserted in special mixing chambers which will further accentuate the mixing.
Il sistema aumenta cosi la velocit? del flusso acqua-aria immesso in vasca. The system thus increases the speed? of the water-air flow introduced into the tank.
Questo apparecchio (AMP) presenta il vantaggio di avere la camera di miscelazione estraibile dalla vasca, smontabile, con ugelli sostituibili in pochissimo tempo, per una rapida ripresa dell'attivit? di ossigenazione - miscelazione. This device (AMP) has the advantage of having the mixing chamber removable from the tank, removable, with nozzles that can be replaced in a very short time, for a quick resumption of activity. of oxygenation - mixing.
?AMP? ? studiato per funzionare con elevate concentrazioni di biomassa in vasca, utilizzando gli ugelli maggiormente adatti alle specifiche esigenze della depurazione. ? AMP? ? designed to work with high concentrations of biomass in the tank, using the nozzles best suited to the specific purification needs.
