Definitions
- the present invention relates to a liquid/gas state separating device capable of separating molecules of vapour of a liquid from drops of said liquid.
- Such a separator is intended to be used in a heat exchanger for implementing cooling of a beverage by an evaporation and adsorption method.
- the principle of such a cooling method consists of evaporating a liquid under the effect of a partial vacuum maintained by adsorption of the vapours of said liquid.
- a refrigerant liquid contained in a heat exchanger is evaporated under vacuum. This evaporation is initiated by a partial vacuum brought about in the exchanger by activation of means of putting the heat exchanger into communication with pumping means, and then this partial vacuum is maintained by pumping the vapours of said liquid.
- the molecules of vapour of the refrigerant liquid are pumped and drops of said liquid can be carried along by the vapour.
- the pumping force can be such that drops of liquid L can be carried along to the pump and thus prejudice its correct operation.
- An evaporator 12 contains a liquid 18 evaporated by pumping by means of desiccants contained in a chamber 20.
- a mixture of vapour and liquid is thus drawn into a collector and liquid/gas state separator 34 of conventional design which separates the liquid carried along by the pumped vapours.
- the collector and state separator 34 has a outlet pipe 38 which returns the drops of liquid to the evaporator 12 and a conduit 28 which opens a way for the vapour to the desiccant chamber 20.
- the present invention proposes a miniaturised liquid/gas state separating device capable of being inserted into a heat exchanger disposed in a beverage package, such as a standardised can for example. More particularly, the invention relates to a liquid/gas state separating device capable of separating the molecules of vapour of a liquid evaporating under the effect of a partial vacuum maintained by pumping means from drops of said liquid carried along by the flow of vapour, characterised in that it comprises a vapour deflector and a drop collector, the vapour deflector imposing at least one sudden change of direction on the flow of vapour.
- the drop collector comprises at least one outlet pipe for the drops of length greater than or equal to the pressure loss of the vapour in the deflector.
- a sudden change of direction of the flow of vapour is an upward movement.
- the total volume of said device is less than or equal to 20 cm 3 .
- the drop collector comprises a funnel, the solid angle of which includes the partial vacuum source and the vapour deflector.
- the vapour deflector comprises at least one wall forming a zigzag, said wall being disposed around the partial vacuum source and inside the solid angle formed by the drop collector.
- the funnel constitutes a zigzag wall of the vapour deflector.
- the device also comprises protection from direct splashes of drops, said protection being disposed opposite the partial vacuum source.
- the device is made of plastic or metal.
- the device is disposed in a heat exchanger containing a refrigerant liquid capable of evaporating under the effect of a partial vacuum maintained by pumping means associated with said exchanger.
- the pumping means are chosen from amongst the means constituted by an adsorbent material packed under air vacuum, a mechanical vacuum pump, and a cryogenic vacuum pump.
- - Figure 1 already described, is a diagram of a known self-cooling device for beverages of the prior art; - Figure 2 illustrates schematically the state separating device according to the invention.
- This device comprises a vapour deflector 50 and a drop collector 60.
- This device can be integrated into a heat exchanger 2 containing a refrigerant liquid L capable of evaporating under the effect of a partial vacuum 31 maintained by pumping means 3.
- the pumping means are associated with the heat exchanger 2 and can consist, according to application, of a mechanical vacuum pump, or cryogenic pumping means such as cold traps which condense the water vapours, or else an evacuated cartridge containing reagents (desiccants) capable of activating and maintaining the adsorption of the refrigerant liquid L.
- a mechanical vacuum pump or cryogenic pumping means such as cold traps which condense the water vapours, or else an evacuated cartridge containing reagents (desiccants) capable of activating and maintaining the adsorption of the refrigerant liquid L.
- the state separating device has a vapour deflector 50 which consists of at least one wall forming a zigzag 51 imposing one or more sudden changes of direction on the flow of vapour V, preferably from the downward direction to the upward direction.
- the vapour molecules have a very small mean free path, of the order of a micrometre, which means they can change direction very quickly.
- the drops of liquid have a mass such that they are carried along by their inertia and thus separated from the gaseous flow. This mechanism advantageously allows liquid/gas separation without significant slowing down of the flow of vapour V and therefore does not require the occupation of a large volume.
- the state separating device also has, in addition, a drop collector 60 making it possible to take the drops of liquid L separated from the gaseous flow of vapour V back to the bottom of the cavity of the evaporator 2.
- the collector 60 comprises- a funnel 61 and at least one outlet pipe 62 for the drops.
- the funnel 61 can advantageously contribute towards forming the zigzag 51 of the vapour deflector 50.
- the vapour deflector 50 is advantageously disposed around the partial vacuum source 31 and the funnel 61 of the drop collector
- 60 defines a solid angle which includes the partial vacuum source 31 and the vapour deflector 50.
- the collector 60 can be connected to the wall of the heat exchanger 2 by webs for example which constitute thin partitions allowing passage of the vapour V while holding the piece of the funnel 61 in position.
- the collector can also be held immovably attached to the zigzag 51.
- the funnel 61 then extends as far as the wall of the heat exchanger 2 containing the partial vacuum source 31 and has louvres allowing passage of the vapour V to the pumping means 3.
- the outlet pipe for the drops 62 has a length greater than or equal to the pressure loss of the vapour V in the zigzag 51 in order to avoid the splashing of drops L through said outlet pipe 62.
- This pressure loss is advantageously measured as a water volume height. If, for example, a pressure loss of the vapour V of 1 mb (corresponding to 1 cm water column height) is considered, the pipe will be at least 1 cm long.
- the state separating device also comprises protection 55 from direct splashes of drops which completes the vapour deflector 50.
- This protection 55 is disposed opposite the partial vacuum source 31 in order to avoid direct contamination of the pumping means 3 in particular upon initiation of the adsorption reaction.
- the liquid/gas state separating device according to the invention makes it possible to achieve the miniaturisation constraints required for applications to beverage packages in that the total volume of said device is less than or equal to 20 cm 3 .
- the state separating device according to the invention can be constituted in plastic material, by moulding, which allows great freedom of shape, or in metal of the same kind as the heat exchanger in which it is disposed, such as aluminium or steel for example, in order to facilitate recycling of the package.
