“DISPOSITIVO BOOSTER PER LA COMPRESSIONE DI GAS†⠀ œBOOSTER DEVICE FOR GAS COMPRESSIONâ €
DESCRIZIONE DESCRIPTION
La presente invenzione si riferisce ad un dispositivo “booster†o moltiplicatore idraulico per la compressione di gas, in particolare idrogeno, e, in particolare, per il riempimento di bombole con tale gas compresso. The present invention refers to a â € œboosterâ € or hydraulic multiplier device for compressing gas, in particular hydrogen, and, in particular, for filling cylinders with this compressed gas.
Nella tecnica à ̈ nota l’esigenza di dovere pressurizzare ed immagazzinare ad alta pressione un volume di gas, come per esempio idrogeno, all’interno di una bombola standard avente capacità di circa 50 litri per permetterne lo stoccaggio: per far ciò occorre pressurizzare il gas con un salto di pressione che può arrivare fino a 160-200 bar. In the art it is known the need to pressurize and store at high pressure a volume of gas, such as hydrogen, inside a standard cylinder with a capacity of about 50 liters to allow storage: to do this it is necessary pressurize the gas with a pressure jump that can reach up to 160-200 bar.
Nel passato, per consentire il riempimento di cui sopra delle bombole venivano utilizzati dei compressori tradizionali ad aria, i quali risultavano però estremamente ingombranti e rumorosi. Per risolvere tali inconvenienti, i suddetti compressori sono stati quindi progressivamente sostituiti con appositi dispositivi “booster†o moltiplicatori con centralina idraulica. Un esempio di tali dispositivi “booster†à ̈ descritto nel documento JP2006152975. In the past, traditional air compressors were used to allow the above mentioned filling of the cylinders, but these were extremely bulky and noisy. To solve these problems, the aforementioned compressors were then progressively replaced with special â € œboosterâ € devices or multipliers with hydraulic power pack. An example of such â € œboosterâ € devices is described in document JP2006152975.
In particolare, i dispositivi “booster†noti sono attualmente utilizzati per la compressione efficiente e lo stoccaggio in bombole d’idrogeno e d’ossigeno generati da un elettrolizzatore per l’impiego in un generatore di energia a “fuel cell†: tali dispositivi presentano però ancora delle criticità dovute al raggiungimento di una elevata temperatura che ne modifica le condizioni iniziali. In particular, known â € œboosterâ € devices are currently used for efficient compression and storage in hydrogen and oxygen cylinders generated by an electrolyser for use in a â € œfuel cellâ € power generator. €: however, these devices still have some criticalities due to the attainment of a high temperature which modifies their initial conditions.
Infatti, durante il funzionamento prolungato, i dispositivi “booster†noti generano un notevole aumento della temperatura, che provoca l’usura e la rottura di alcuni componenti ed obbliga ad alternare fasi di esercizio a fasi di riposo per dare modo alla temperatura di abbassarsi, con conseguente dilatazione dei tempi di ripristino dello stoccaggio. Il surriscaldamento provoca inoltre una dilatazione non omogenea dei diversi materiali impiegati, l’aumento dei fenomeni di attrito, una maggiore reattività dell’idrogeno, il degrado delle guarnizioni con conseguenti problemi di trafilamento che possono provocare il blocco del dispositivo “booster†. In fact, during prolonged operation, known â € œboosterâ € devices generate a considerable increase in temperature, which causes wear and tear of some components and forces to alternate operating phases with rest phases to give way to the temperature of lower, with consequent expansion of the storage restoration times. Overheating also causes non-homogeneous expansion of the various materials used, an increase in friction phenomena, greater hydrogen reactivity, degradation of the gaskets with consequent leakage problems that can cause the â € œboosterâ € device to block .
Scopo quindi della presente invenzione à ̈ quello di risolvere i suddetti problemi della tecnica anteriore fornendo un dispositivo “booster†o moltiplicatore idraulico per la compressione di gas e, in particolare, per il riempimento di bombole con tale gas compresso comprendente un sistema di raffreddamento a fluido che ne impedisce il surriscaldamento e pertanto ne migliora l’efficienza. Therefore, the purpose of the present invention is to solve the aforementioned problems of the prior art by providing a `` booster '' device or hydraulic multiplier for the compression of gas and, in particular, for the filling of cylinders with this compressed gas comprising a cooling system fluid which prevents overheating and therefore improves its efficiency.
Un altro scopo della presente invenzione à ̈ quello fornire un dispositivo “booster†o moltiplicatore idraulico per la compressione di gas e, in particolare, per il riempimento di bombole con tale gas compresso dotato di almeno un circuito di raffreddamento di almeno un fluido di raffreddamento circolante all’interno del dispositivo stesso ed in grado di abbassare la temperatura di esercizio e di evitare quindi l’insorgenza delle criticità dei dispositivi della tecnica nota. Another object of the present invention is to provide a `` booster '' device or hydraulic multiplier for the compression of gas and, in particular, for the filling of cylinders with this compressed gas equipped with at least one cooling circuit of at least one fluid of cooling circulating inside the device itself and capable of lowering the operating temperature and thus avoiding the onset of criticalities of the devices of the known art.
Inoltre, uno scopo della presente invenzione à ̈ quello fornire un dispositivo “booster†o moltiplicatore idraulico per la compressione di gas e, in particolare, per il riempimento di bombole con tale gas compresso che risulti di ingombri inferiori e di rumorosità meno elevata, grazie all’eliminazione del compressore d’aria e del serbatoio dell’aria compressa, rispetto ai dispositivi della tecnica nota. Furthermore, an object of the present invention is to provide a â € œboosterâ € or hydraulic multiplier device for the compression of gas and, in particular, for the filling of cylinders with this compressed gas which results in smaller dimensions and less noise, thanks to the elimination of the air compressor and the compressed air tank, compared to the devices of the prior art.
I suddetti ed altri scopi e vantaggi dell’invenzione, quali risulteranno dal seguito della descrizione, vengono raggiunti con un dispositivo “booster†o moltiplicatore idraulico per la compressione di gas e, in particolare, per il riempimento di bombole con tale gas compresso come quello descritto nella rivendicazione 1.
