?SISTEMA DI FILTRAGGIO DELL?ARIA A MANUTENZIONE AUTOMATICA ALTERNATA E CONTROLLO REMOTO? ?AIR FILTERING SYSTEM WITH AUTOMATIC ALTERNATING MAINTENANCE AND REMOTE CONTROL?
Descrizione Description
Campo della tecnica field of technique
L?invenzione si inserisce nell?ambito dei sistemi per il filtraggio, la purificazione e la sanitizzazione dell?aria e si riferisce all?abbattimento di patogeni, batteri, polveri o sostanze chimiche presenti in ambienti interni destinati all?uso civile. Arte nota The invention is part of the field of systems for filtering, purifying and sanitizing the air and refers to the elimination of pathogens, bacteria, dust or chemical substances present in internal environments intended for civil use. Known art
La maggior parte delle persone passa tra il 75 e il 90% della propria giornata in un luogo chiuso non sapendo che, almeno secondo l?EPA (Environmental Protection Agency), il livello di inquinamento dell?aria interna pu? essere anche 100 volte pi? alto di quello dell?aria esterna. Particolato (polvere, forfora, fuliggine, amianto, fibre di lana sintetiche, polline, particelle di fumo, etc.), microbi (batteri, germi, virus, funghi, spore e muffe) e gas di vario tipo a seconda delle tipologie di prodotti utilizzati e/o di apparecchi o macchinari in funzione (monossido di carbonio, radon, acetaldeide, benzene, formaldeide, cloroformio, ammoniaca, composti organici volatili, etc.) sono tra le sostanze che immettiamo continuamente nei nostri polmoni all?interno degli ambienti chiusi senza averne una minima contezza e che, con il tempo, vanno ad inficiare la nostra salute. Most people spend between 75 and 90 percent of their day indoors not knowing that, at least according to the Environmental Protection Agency (EPA), the level of indoor air pollution can lead to pollution. be even 100 times more? higher than that of the outside air. Particulate matter (dust, dandruff, soot, asbestos, synthetic wool fibres, pollen, smoke particles, etc.), microbes (bacteria, germs, viruses, fungi, spores and moulds) and various types of gas depending on the type of product used and/or of operating appliances or machinery (carbon monoxide, radon, acetaldehyde, benzene, formaldehyde, chloroform, ammonia, volatile organic compounds, etc.) are among the substances that we continuously introduce into our lungs inside closed environments without having the slightest knowledge of it and which, over time, affect our health.
Diversi studi hanno indicato una forte correlazione fra esposizione ad ambienti interni inquinati e manifestazioni cliniche come mal di testa, stanchezza, difficolt? di concentrazione, irritazione di occhi, naso, gola e polmoni, allergie e asma, tanto da portare alla definizione di una ?sindrome dell?edificio malato? (Sick Building Syndrome, SBS). Altri studi recenti hanno invece rilevato addirittura la presenza nell?aria di legionella e di ?bacillus subtilis?, un batterio che causa dei sintomi simili all?influenza e che vengono denominati ?febbre degli umidificatori?. Several studies have indicated a strong correlation between exposure to polluted indoor environments and clinical manifestations such as headache, tiredness, difficulty concentration, irritation of the eyes, nose, throat and lungs, allergies and asthma, so much so as to lead to the definition of a ?sick building syndrome? (Sick Building Syndrome, SBS). Other recent studies have instead even found the presence in the air of legionella and ?bacillus subtilis?, a bacterium that causes flu-like symptoms and which are called ?humidifier fever?.
Per far fronte a questa situazione nota da tempo, sono stati messi a punto diversi dispositivi per il trattamento, la decontaminazione, la purificazione e la conduzione dell?aria pulita negli ambienti, ai quali si associano filtri con una elevatissima capacit? filtrante (gli U17 possono arrivare al 99,999995% di efficienza) e capacit? di trattenere particelle fino alla misura di 0.3 ?m. Il problema di questi impianti, per?, ? che i filtri tendono ad intasarsi progressivamente e a diminuire la portata interna del circuito man mano che raccolgono le impurit?, sforzando la ventilazione e diminuendo progressivamente la qualit? dell?aria prodotta. La conseguenza ? che per mantenere l?efficienza di un sistema di filtrazione nel tempo, ovvero per continuare a garantire la salute degli occupanti anche in considerazione delle norme vigenti, si rendono necessarie la manutenzione continua e la frequente sostituzione delle batterie filtranti, azioni, queste, che si associano alla presenza costante di manutentori umani e a una regolare spesa economica di rilievo. To deal with this situation known for some time, various devices have been developed for the treatment, decontamination, purification and conduction of clean air in environments, which are associated with filters with a very high capacity? filtering (the U17 can reach 99.999995% efficiency) and capacity? to retain particles up to the size of 0.3 ?m. The problem of these systems, however?, ? that the filters tend to clog progressively and to decrease the internal flow rate of the circuit as they collect the impurities, straining the ventilation and progressively decreasing the quality? of the air produced. The consequence ? that to maintain the efficiency of a filtration system over time, or to continue to guarantee the health of the occupants also in consideration of the regulations in force, continuous maintenance and frequent replacement of the filter batteries are necessary, actions which associated with the constant presence of human maintainers and a regular significant economic expense.
La presenza della recente pandemia da Sars-Cov-2 ha infine aumentato la consapevolezza da parte dei gestori degli ambienti nei riguardi del problema dell?inquinamento interno, aumentando la necessit? percepita, ma anche oggettiva, della messa in esercizio di impianti di filtraggio e sanificazione dell?aria in un numero sempre maggiore di edifici e ambienti, sia privati che pubblici, determinando altres? la ricerca e la sperimentazione di soluzioni sempre pi? efficienti. Finally, the presence of the recent Sars-Cov-2 pandemic has increased awareness on the part of room managers regarding the problem of internal pollution, increasing the need for perceived, but also objective, of the commissioning of air filtering and sanitizing systems in an ever-increasing number of buildings and environments, both private and public, also determining the search and experimentation of solutions more and more? efficient.
Lo scopo della presente domanda di brevetto per invenzione industriale ? allora quello di proporre un sistema di filtraggio dell?aria che sia in grado di risolvere i problemi appena esposti, attraverso una manutenzione automatica, ossia che non richieda la presenza di un manutentore n? frequenti ricambi dei filtri, e alternata, ossia che garantisca un servizio ininterrotto mediante l?utilizzo di due condotte parallele, mantenendo costante la portata e garantendo contemporaneamente l?assoluta qualit? e sanificazione dell?aria erogata. L?invenzione ? anche dotata di sensori interni in grado di avvertire il manutentore da remoto in caso di guasti, malfunzionamenti, differenze rilevanti di pressione di carico e presenza di sostanze contaminanti. The purpose of this patent application for industrial invention? then that of proposing an air filtering system that is able to solve the problems just described, through automatic maintenance, i.e. that does not require the presence of a maintainer or? frequent replacement of the filters, and alternating, i.e. which guarantees an uninterrupted service through the use of two parallel pipes, keeping the flow rate constant and guaranteeing at the same time the absolute quality? and sanitization of the air supplied. The invention? also equipped with internal sensors able to warn the maintenance technician remotely in the event of failures, malfunctions, significant differences in load pressure and the presence of contaminating substances.
Descrizione dell?invenzione Description of the invention
Con la presente domanda di brevetto per invenzione industriale si intende descrivere e rivendicare un sistema dotato di almeno una soluzione nuova e alternativa alle soluzioni finora note, per soddisfare una o pi? esigenze avvertite nella tecnica e in particolare evincibili da quanto sopra riferito. Per assolvere questo scopo, gli inventori hanno messo a punto un efficace sistema di filtraggio dell?aria il quale, mediante l?utilizzo di almeno due condotte parallele e alternative, effettua la manutenzione automatica dei filtri senza mai interrompere l?erogazione. Tale sistema si realizza attraverso lo sdoppiamento di una condotta d?aria principale in almeno due condotte parallele, le quali entrano in azione alternativamente prima di riconfluire entrambe nella porzione terminale della condotta principale. Il flusso d?aria proveniente dalla condotta principale viene, attraverso una serranda con un meccanismo di apertura/chiusura posta a livello del primo snodo ad ?Y?, alternativamente indirizzato verso l?una o verso l?altra delle due condotte parallele, di modo che una possa operare il filtraggio dell?aria mentre l?altra opera la manutenzione del filtro, per poi essere guidato, attraverso una seconda serranda con altro meccanismo di apertura/chiusura posta sul secondo snodo ad ?Y? rovesciata, nella porzione terminale della condotta principale che va ad erogarlo negli ambienti. With the present patent application for an industrial invention it is intended to describe and claim a system equipped with at least one new and alternative solution to the hitherto known solutions, to satisfy one or more? needs perceived in the technique and in particular inferable from the above. To fulfill this purpose, the inventors have perfected an effective air filtering system which, through the use of at least two parallel and alternative ducts, carries out automatic maintenance of the filters without ever interrupting the supply. This system is achieved through the splitting of a main air duct into at least two parallel ducts, which come into action alternately before both flowing back into the terminal portion of the main duct. The air flow coming from the main duct is alternately directed towards one or the other of the two parallel ducts through a damper with an opening/closing mechanism placed at the level of the first ?Y? joint that one can operate the filtering of the air while the other operates the maintenance of the filter, to then be guided through a second shutter with another opening/closing mechanism placed on the second ?Y? reversed, in the terminal portion of the main duct that supplies it to the rooms.
Entrambe le condotte parallele sono dotate di una batteria filtrante connessa ad un avanzato meccanismo di lavaggio ad ugelli e lampade UV; quando il sistema di controllo riscontra l?intasamento di una delle due batterie filtranti, questa entra automaticamente in manutenzione e ha inizio il ciclo di lavaggio. Questo effettua un primo passaggio chimico con disinfettante, che ? in grado di detergere la superficie filtrante abbattendo le sostanze patogene, un secondo passaggio di risciacquo con getto d?acqua in pressione e un terzo passaggio con raggi UV, di cui sono note le propriet? di sterilizzazione. L?acqua contaminata residua viene raccolta in una vaschetta posta al di sotto della batteria filtrante, trattata con declorante e destinata ad un successivo trattamento prima dello scarico o del riutilizzo. Both parallel ducts are equipped with a filtering battery connected to an advanced washing mechanism with nozzles and UV lamps; when the control system detects the blockage of one of the two filter batteries, this automatically enters maintenance mode and the washing cycle begins. This carries out a first chemical passage with disinfectant, which ? able to cleanse the filtering surface by breaking down the pathogenic substances, a second rinsing passage with a pressurized water jet and a third passage with UV rays, whose properties are known? of sterilization. The residual contaminated water is collected in a tray placed under the filtering battery, treated with dechlorinator and destined for subsequent treatment before being discharged or reused.
Terminato il ciclo di lavaggio, la serranda posta a monte della condotta in manutenzione si apre, il flusso d?aria riprende, mentre l?altra condotta parallela si chiude al flusso dell?aria e inizia il suo ciclo di lavaggio. At the end of the washing cycle, the damper located upstream of the duct under maintenance opens, the air flow resumes, while the other parallel duct closes to the air flow and begins its washing cycle.
Per poter funzionare in automatico, il sistema richiede la presenza di due pressostati su ognuna delle condotte parallele, uno posto in precedenza e uno successivo alla batteria filtrante; la funzione dei due pressostati ? duplice: la prima ? quella di controllare che il filtro non sia intasato, verificando che vi sia la giusta differenza di pressione tra i due lati; la seconda ? quella di gestire il sistema di ventilazione posto in aspirazione nella porzione terminale della condotta principale, di modo che vi sia sempre una portata d?aria costante all?interno del sistema: quando i filtri sono nuovi, infatti, hanno una resistenza minore al flusso e non avrebbe senso mantenere un?elevata ventilazione che creerebbe un maggiore consumo di energie ed esporrebbe i filtri stessi ad una maggiore velocit? di intasamento. In questo caso, l?aspirazione viene regolata su un carico di portata pi? basso. Viceversa, quando la differenza di pressione tra i due lati del filtro aumenta e quindi il filtro inizia ad essere intasato, il sistema regola la portata della ventilazione a valori maggiori, di modo che il carico resti costante. Quando infine la differenza di pressione raggiunge una soglia stabilita, allora significa che il filtro ? intasato e ha bisogno di manutenzione: in questo caso la condotta viene chiusa dalle due serrande poste a monte e a valle del sistema e il ciclo di lavaggio viene attivato, mentre la seconda condotta parallela viene liberata dalle relative serrande e prosegue il filtraggio e l?erogazione dell?aria, prevenendone l?interruzione. In prossimit? della ventola di aspirazione posta sulla porzione terminale della condotta principale vengono infine posti un sistema di sensori per la rilevazione di sostanze inquinanti e contaminanti eventualmente presenti nell?aria, come particolati e altre sostanze patogene, i quali sensori, collegati ad una centralina elettronica di controllo in grado di avvertire l?utente remoto che gestisce il sistema, hanno il compito di verificare che i filtri stiano effettivamente purificando l?aria e non debbano essere sostituiti. In order to operate automatically, the system requires the presence of two pressure switches on each of the parallel pipes, one placed before and one after the filtering coil; the function of the two pressure switches ? double: the first ? that of checking that the filter is not clogged, verifying that there is the right pressure difference between the two sides; the second ? that of managing the ventilation system placed on suction in the terminal portion of the main duct, so that there is always a constant air flow inside the system: when the filters are new, in fact, they have less resistance to the flow and wouldn't it make sense to maintain a? high ventilation which would create a greater consumption of energy and would expose the filters themselves to a greater speed? of clogging. In this case, the suction is adjusted to a higher flow load. Bass. Conversely, when the pressure difference between the two sides of the filter increases and therefore the filter starts to get clogged, the system adjusts the ventilation flow rate to higher values, so that the load remains constant. Finally, when the pressure difference reaches a set threshold, does this mean that the filter is ? clogged and needs maintenance: in this case the duct is closed by the two dampers located upstream and downstream of the system and the washing cycle is activated, while the second parallel duct is released from the relative dampers and continues filtering and dispensing the water ?air, preventing its?interruption. in the vicinity? of the suction fan placed on the terminal portion of the main duct are finally placed a system of sensors for the detection of pollutants and contaminants possibly present in the air, such as particulates and other pathogenic substances, which sensors, connected to an electronic control unit able to warn the remote user who manages the system, they have the task of verifying that the filters are actually purifying the air and do not need to be replaced.
