SYSTEME DE STOCKAGE ECHELONNE D'AIR COMPRIME COMPRESSED AIR STORAGE STORAGE SYSTEM
cS Nota : on entend par manomètre un appareil susceptible de commander l'arrêt ou la mise en marche d'un appareil, ici l'ouverture ou la fermeture de clapets ou soupapes, comme le fait un disjoncteur pour arrêter ou mettre en marche le moteur d'un compresseur. 4i7 L'idée de stockage échelonné d'air comprimé est d'apporter un complément d'air au réservoir principal lorsque le contenu de celui-ci devient insuffisant. Initialement le système se comporte comme un réservoir de compresseur classique avec un apport d'air (1) vers le réservoir `principal R.P. et une sortie d'air (16) vers la sortie d'utilisation d'air (13) dont la pression d'utilisation est régulée par un régulateur de pression (14). L'apport d'air (1) peut représenter un compresseur. La particularité de ce système est que la valve (3) ouvre 2. O l'alimentation de R.P. et ferme (2) lors du remplissage du réservoir R .P. comme indiqué sur la figure 1, se ferme comme indiqué sur la figure 2, ouvrant l'accès à (2) lorsque la pression dans le réservoir atteint son niveau de pression maximum gérée par le manomètre (4). Dans les compresseurs classiques, le manomètre 2.514) commande l'arrêt du compresseur d'air. En conséquence, dans le cas de la figure 1, quand l'entrée du réservoir R.P. est fermée, l'air comprimé se dirige par (2) vers le réservoir complémentaire R.C. qui se remplit et dont le manomètre (5) commande l'arrêt d'apport d'air (1) lorsque la pression 3 maximum est atteinte. Ce manomètre commande également l'ouverture de (1) lorsque la pression de l'air descend au niveau désiré de démarrage. Un tuyau (17) relie le R.C. au tuyau de sortie d'air (16). Un clapet (10) interdit le transfert d'air du R.P. vers le R.C. mais permet la circulation d'air de R.C. vers R.P. 3S La deuxième particularité de ce système est d'ajouter en cas de nécessité au moins un réservoir intermédiaire R.I. Chacun de ces réservoirs est relié au tuyau de chargement (2) et leur remplissage ou isolement est commandé par l'intermédiaire d'un système de fermeture/ouverture par clapets. Sur la figure 2 on 4 dote que le premier réservoir est plein car le clapet (7) est fermé et la circulation d'air dans (2) ouverte, commandé par (6). Dans cette même figure le clapet (9) est ouvert et la charge du réservoir correspondant s'effectue et s'arrêtera si la pression maximum est atteinte commandée par (8) et ainsi successivement jusqu'au 4 ,.5--remplissage du dernier R.I... Le dernier réservoir R.I. étant - cS Note: Manometer means a device capable of controlling the stopping or starting of a device, here the opening or closing of valves or valves, as does a circuit breaker to stop or start the engine of a compressor. The idea of staggered storage of compressed air is to provide additional air to the main reservoir when the contents thereof become insufficient. Initially the system behaves like a conventional compressor tank with a supply of air (1) to the main tank RP and an air outlet (16) to the air utilization outlet (13) whose pressure of use is regulated by a pressure regulator (14). The supply of air (1) can represent a compressor. The peculiarity of this system is that the valve (3) opens 2. O feeding R.P. and closes (2) when filling the tank R .P. as shown in Figure 1, closes as shown in Figure 2, opening the access to (2) when the pressure in the tank reaches its maximum pressure level managed by the pressure gauge (4). In conventional compressors, the pressure gauge 2.514) controls the shutdown of the air compressor. Consequently, in the case of FIG. 1, when the inlet of the reservoir RP is closed, the compressed air is directed by (2) towards the complementary tank RC which fills up and whose pressure gauge (5) controls the stop supply air (1) when the maximum pressure 3 is reached. This manometer also controls the opening of (1) when the air pressure drops to the desired starting level. A pipe (17) connects the R.C. to the air outlet pipe (16). A valve (10) prohibits the transfer of air from the RP to the RC but allows the flow of air from RC to RP 3S The second feature of this system is to add if necessary at least one intermediate tank RI Each these tanks are connected to the loading pipe (2) and their filling or isolation is controlled by means of a closing / opening system by valves. In Figure 2 it is 4 that the first tank is full because the valve (7) is closed and the air flow in (2) open, controlled by (6). In this same figure the valve (9) is open and the load of the corresponding reservoir is effected and will stop if the maximum pressure is reached controlled by (8) and thus successively up to 4, .5 - filling the last RI .. The last RI tank being -
plein, le chargement de R.C. s'effectue. La sortie d'air des R.I. (18) est reliée à (16) mais des clapets (11), (12) ne permettent la sortie d'air des R.I. qu'à partir d'une pression pré-établie. Il est à noter qu'un manomètre ou autre système de sécurité (15) compense sur R.P. une éventuelle défaillance de (5). La flèche (19) symbolise une éventuelle évacuation vers une purge du réseau. Il est également à noter que les réservoirs peuvent être de forme sphérique, cylindrique ou de tuyaux, ces derniers pouvant avoir d'importantes longueurs et supportant de très grandes pressions. Supposons que la pression admise est de 30 bars : quand R.P. est plein, le clapet (3) en ferme l'accès et le clapet (7) étant ouvert ~6-le premier réservoir RI se remplit à son tour jusqu'à ce que le système (6) commande sa fermeture à 30 bars ouvrant le passage vers le R.I. suivant, et ainsi successivement jusqu'au remplissage de R.C. qui commande par (5) l'arrêt de (1). Le clapet (10), de faible puissance, libère l'air de R.C. dès 2(1'utilisation de (13) et de la pression établie pour la réouverture de (1). Si les régulateurs de pression (11), (12), etc. opposent, par exemple, une résistance de cinq bars, l'apport d'air des R.I. n'intervient dans ce cas qu'au dessous d'une pression de 25 bars en (16). Cette différence de puissance des clapets (10) et des 2 $régulateurs de pression (11), (12), etc. permet de n'utiliser que le volume d'air de R.P. plus R.C.. Il est également aisé de prévoir des dérivations pour isoler les R.I. en fermant leurs entrée et sortie au moyen de robinets ou soupapes ou tout autre moyen jugé opportun. Les sorties (13) peuvent également être multiples. 3 ,D L'avantage de ce système est que le R.P. étant calculé pour une utilisation moyenne, il n'est pas nécessaire de remplir tous les réservoirs pour obtenir la pression d'utilisation minimum, cela permettant de disposer d'air à la pression minimum voulue dans un minimum de temps. Les réserves dans les autres réservoirs se 3 5-constituent pendant les périodes de faible utilisation et servent à compenser les demandes supérieures à la normale. full, the loading of R.C. is carried out. The air outlet of the R.I. (18) is connected to (16) but valves (11), (12) allow the air outlet of the R.I. only from a pre-established pressure. It should be noted that a manometer or other safety system (15) compensates for R.P. a possible failure of (5). The arrow (19) symbolizes a possible evacuation towards a purge of the network. It should also be noted that the tanks may be spherical, cylindrical or pipes, the latter may have significant lengths and support very high pressures. Suppose that the admissible pressure is 30 bar: when RP is full, the valve (3) closes the access and the valve (7) being open ~ 6-the first reservoir RI fills in turn until the system (6) controls its closing at 30 bars opening the passage to the next RI, and thus successively until filling RC which controls (5) the stop of (1). The valve (10), of low power, releases RC air from 2 (the use of (13) and the pressure established for the reopening of (1).) If the pressure regulators (11), (12) ), etc., for example, a resistance of five bars, the air intake of the RI is involved in this case only below a pressure of 25 bar in (16). valves (10) and 2 $ pressure regulators (11), (12), etc. allows to use only the volume of air RP plus RC.It is also easy to provide derivations to isolate the RI in closing their entry and exit by means of taps or valves or any other means considered appropriate.The outputs (13) can also be multiple 3, D The advantage of this system is that the RP being calculated for average use, it is It is not necessary to fill all the tanks to obtain the minimum operating pressure, this making it possible to have air at the desired minimum pressure s a minimum of time. Reserves in other reservoirs are formed during periods of low use and serve to compensate for higher than normal demands.
