Description
La présente invention concerne un procédé de récupération, d'accumulation et de restitution de l'énergie mécanique excédentaire disponible d'une machine motrice à régime de consommation variable, par transformation en énergie de pression statique dans un fluide gazeux compressible, et un dispositif pour la mise en oeuvre dudit procédé. The present invention relates to a method for recovering, accumulating and restoring the excess mechanical energy available from a motive machine with variable consumption regime, by transformation into static pressure energy in a compressible gaseous fluid, and a device for the implementation of said process.
On connait déjà un procédé de récupération, d'accumulation, et de restitution d'énergie mécanique excédentaire disponible, dans lequel l'éxcédent d'énergie d'une centrale électrique, pendant les périodes creuses de consommation d'énergie, est utilisé pour comprimer de l'air atmosphérique qui est ensuite accumulé dans une cavité souterraine créée généralement par dissolution d'un dôme de sel ou artificiellement pourvue d'un sytème de régulation automatique de la pression d'air pour la maintenir constante. Ce système basé sur le principe du piston hydraulique, utilise, par exemple, une nappe phréatique de façon que cette masse d'eau forme le piston hydraulique surmonté par la masse d'air comprimé accumulée dans la cavité souterraine. There is already known a process for recovering, accumulating, and restoring available excess mechanical energy, in which the excess energy of a power plant, during off-peak periods of energy consumption, is used to compress atmospheric air which is then accumulated in an underground cavity generally created by dissolution of a salt dome or artificially provided with a system of automatic regulation of the air pressure to keep it constant. This system based on the principle of the hydraulic piston, uses, for example, a water table so that this mass of water forms the hydraulic piston surmounted by the mass of compressed air accumulated in the underground cavity.
L'air comprimé soutiré de la cavité souterraine, utilisée comme réserve de stockage, alimente directement la chambre de combustion du générateur de gaz d'une turbine, dont on a supprimé le compresseur d'air comburant. The compressed air drawn from the underground cavity, used as a storage reserve, directly feeds the combustion chamber of the gas generator of a turbine, from which the combustion air compressor has been removed.
Mais, ce procédé présente l'inconvénient majeur de nécessiter l'existence, à proximité du lieu de récupération d'énergie, d'un site naturel susceptible de convenir à la création d'une cavité impérméable de volume suffisamment important, ainsi qu'une nappe phréatique à niveau variable. However, this method has the major drawback of requiring the existence, near the place of energy recovery, of a natural site capable of being suitable for the creation of an impermeable cavity of sufficiently large volume, as well as a variable level water table.
En effet, à défaut d'une telle cavité on ne peut envisager la construction d'un réservoir extérieur en beton en raison de son encombrement considérable nécessaire stockage du fluide à l'état gazeux) donc de son coût prohibitif.In fact, in the absence of such a cavity, it is not possible to envisage the construction of an external concrete tank because of its considerable bulk required for storage of the fluid in the gaseous state) and therefore of its prohibitive cost.
On connait également un dispositif de récupération sans accumulation, d'énergie. Dans ce dispositif, on utilise au moins une partie du vaporiseur d'un système de stockage de gaz naturel liquéfié, destiné à alimenter un gazoduc en gaz naturel en phase vapeur à haute pression comme source froide d'un échangeur de chaleur formant le condenseur d'un cycle fermé de Rankine à fluide cryogénique tel que par exemple un hydrocarbure halogéné ledit dispositif comprenant en outre une pompe à condensat, un évaporateur à source chaude généralement naturelle, telle que l'air ou l'eau, et une machine de détente produisant de l'énergie mécanique utilisable. There is also known a device for recovery without accumulation of energy. In this device, at least part of the vaporizer of a liquefied natural gas storage system is used, intended to supply a gas pipeline in natural gas in high pressure vapor phase as the cold source of a heat exchanger forming the condenser d '' a closed Rankine cycle with cryogenic fluid such as for example a halogenated hydrocarbon said device further comprising a condensate pump, a generally natural hot source evaporator, such as air or water, and an expansion machine producing usable mechanical energy.
Toutefois, ce dispositif ne permet pas l'accumulation de l'énergie récupérée et, d'autre part la localisation géographique de tels dispositifs est très limitée du fait qu'il faut disposer de gaz naturel liquéfié à proximité. However, this device does not allow the accumulation of the recovered energy and, on the other hand, the geographic location of such devices is very limited because it is necessary to have liquefied natural gas nearby.
La présente invention a pour but d'éviter les inconvénients précités en fournissant une solution qui permette de récupérer et d'accumuler l'énergie mécanique excédentaire disponible d'une machine motrice en tout lieu où la récupération et l'accumulation d'une telle énergie sont envisageables, et d'utiliser, pour ce faire, notamment l'air atmosphérique, disponible partout gratuitement et non polluant. The object of the present invention is to avoid the aforementioned drawbacks by providing a solution which makes it possible to recover and accumulate the excess mechanical energy available from a motive machine in any place where the recovery and accumulation of such energy are possible, and to do this, in particular atmospheric air, available everywhere free of charge and non-polluting.

- à vaporiser ladite partie sous une pression sensiblement constante et à température ambiante
- à la détendre dans une machine réceptrice pour produire du travail -utilisable.According to the present invention, this solution consists of a process for recovering, accumulating and restoring the excess mechanical energy available from a motive machine, for example a power generator with variable consumption regime, in particular during off-peak periods. of energy consumption, by transformation into static pressure energy in a compressible gaseous fluid, such as in particular atmospheric air, with subsequent storage of fluid, characterized in that it consists in liquefying the compressed gaseous fluid at the store, preferably at a pressure close to atmospheric pressure, in the liquid state, then take at least part of the liquefied fluid and successively

Said vaporisnur It is connected to the expansion receiver machine C which comprises a set of turbines 12 with intermediate air or water heaters 13.
Le dispositif décrit ci-dessus fonctionne de la manière suivante. The device described above operates in the following manner.
Le générateur de puissance 1 à régime de consommation variable, est couplé pendant les heures creuses de consommation d'énergie, notamment par un accouplement temporaire à embrayage et débrayage automatique,à un compresseur 2 qui comprime de l'air atmosphérique en utilisant l'énergie mécanique excédentaire disponible dudit générateur. The power generator 1 with variable consumption regime, is coupled during off-peak hours of energy consumption, in particular by a temporary coupling with automatic clutch and disengage, to a compressor 2 which compresses atmospheric air using energy excess mechanical available from said generator.
L'air comprimé est refroidi, préliminairement, dans l'échangeur thermique 3 et, de préférence, dans l'échangeur thermique supplémentaire 6, puis une partie mineure de l'air comprimé refroidi est détendue dans la turbomachine 4 et utilisée comme source froide du condenseur 5, où la majeure partie de l'air comprimé et refroidi est liquéfiée, et comme source froide de l'échangeur thermique supplémentaire 6. La puissance mécanique fournie à la turbomachine 4 précitée est utilisée pour comprimer, de façon auxiliaire, l'air atmosphérique dans le compresseur précité 2. The compressed air is cooled, preliminary, in the heat exchanger 3 and, preferably, in the additional heat exchanger 6, then a minor part of the cooled compressed air is expanded in the turbomachine 4 and used as the cold source of the condenser 5, where most of the compressed and cooled air is liquefied, and as the cold source of the additional heat exchanger 6. The mechanical power supplied to the aforementioned turbomachine 4 is used to compress, in an auxiliary manner, the air atmospheric in the aforementioned compressor 2.
L'air liquéfié est conservé dans le réservoir de stockage 8 à une pression voisine de la pression atmosphérique et la partie évaporée dudit air liquéfié sert de source froide complémentaire de l'échangeur thermique supplémentaire 6. The liquefied air is kept in the storage tank 8 at a pressure close to atmospheric pressure and the evaporated part of said liquefied air serves as a complementary cold source to the additional heat exchanger 6.
L'air liquéfié accumulé est prélevé et pompé à une pression d'environ 60 bars avant d'être vaporisé, sous une pression sensiblement constante et à une température ambiante, etdétendu de façon sensiblement isotherme dans l'ensemble de turbines 12 pour produire du travail utilisable. The accumulated liquefied air is removed and pumped at a pressure of about 60 bars before being vaporized, under a substantially constant pressure and at room temperature, and expanded in a substantially isothermal manner in the set of turbines 12 to produce work. usable.
Ainsi, le procédé selon l'invention permet de récuperer et de stocker de l'énergie excédentaire disponible d'un générateur de puissance à régime de consommation variable partout où cela est envisageable. En effet, le stockage s'effectue dans un réservoir d'air liquide de volume restreint qui peut être de ce fait installé n'importe où sans difficultés. Thus, the method according to the invention makes it possible to recover and store the excess energy available from a power generator with a variable consumption regime wherever it is possible. In fact, the storage takes place in a liquid air reservoir of limited volume which can therefore be installed anywhere without difficulty.
