Abstract

A device for separating fluids, which can applied in the automotive, nautical, aeronautical, industrial, civil, military, agricultural, chemical and/or domestic field, is here described.

Description

DEVICE FOR SEPARATING FLUIDS

FIELD OF THE INVENTION

The present invention relates to a device for separating fluids, which can be applied in the automotive, nautical, aeronautical, industrial, civil, military, agricultural, chemical and/or domestic field.

BACKGROUND OF THE INVENTION

In physics, the term "fluids" usually indicates a material (generally consisting of a substance or of a mixture of several substances) which is unlimitedly deformed (flows) if subjected to a cutting effort. A fluid is a particular state of matter that includes liquids, aeriforms, plasma and, in some cases, plastic solids.

Differences between solids and fluids

Usually it is customary to distinguish fluids from solids because the latter have their own shape, while the fluids take the shape of the vessel in which they are contained. In the solids, the efforts which are generated following a deformation are a function of the deformation itself, while in fluids the efforts are proportional to the speed of deformation. The fluid behaviour is characterized by viscosity while the solid one from the modulus of elasticity (or Young). At the molecular level this means that two fluid particles initially contiguous can be moved away from one another indefinitely even by a small and constant force; once the deforming cause has ceased, the particles do not tend to come together again (elastic return) and this is due to the different magnitude of the intermolecular forces acting inside a solid or a liquid.

Such clear distinction is in fact an approximation, the truth is that in all the real materials the efforts are a function of both deformation and deformation speed. The clear prevalence of one behaviour over the other determines belonging to one or the other category. There are materials for which both behaviour coexist and it is not possible to neglect either one; in this case one speaks of viscoelastic fluids (or solids). The science that is concerned with studying the constitutive link between stress and deformation is called rheology.

Difference between liquids and aeriforms

The liquids are different from the aeriforms for the fact that they form a "free" surface (not created by the container in which the liquid is placed), which does not happen in gases. The definition of plastic solids as fluids is not so simple, and in this regard the viscosity of the material can be considered.

Newtonian and non-Newtonian fluids

Depending on how the effort depends on the deformation rate of the fluid, they can be classified as:

• Newtonian fluids: for which the efforts are directly proportional to the speed of deformation;

• Non-Newtonian fluids: where the effort is not directly proportional to the speed of deformation.

The behaviour of fluids is described by a series of partial differential equations, based on the laws of mass conservation, of the momentum balance and of energy conservation (said equations for the Newtonian fluids are said Navier-Stokes equations. BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to a device for separating fluids, which can be applied in the automotive, nautical, aeronautical, industrial, civil, military, agricultural, chemical and/or domestic field.

The device for separating fluids of the present invention was conceived both for the separation of different fuels (for example natural gas and LPG) inside the same tank of an automobile, and for separating fluids in industrial, civil, military or agricultural field, such as for example for the storage of different substances in industrial tanks or silos, or for domestic use, therefore on a reduced scale (small sizes), such as for example for the separation of air from a sparkling drink contained within a bottle, in order to avoid that said sparkling drink looses gas coming into contact with the air. Furthermore, said fluid separating device could also be useful to avoid that the fluid and the walls of the tank (or of the container) come into contact with each other: consider, for example, corrosive fluids which can be corrosive for the walls of the tank (or container), thus damaging said walls of the tank (or container). Alternatively, consider fluids that can instead be themselves damaged or contaminated by contact with the walls of the tank (or container). This can also be valid for domestic applications, for example in the case of a drink or water contained in a plastic bottle which, where separated from contact with the plastic container, would not risk phthalates contamination contained in the plastic walls of the bottle, released through the plastic degradation in time.

It is clear as from now how wide is the range of possible fields of application of the fluid separating device of the present invention, well beyond the examples reported below, which are therefore to be considered by way of a non-limiting examples.

EXAMPLES

EXAMPLE 1

Working of the device of Figures 1 and 2 The device of Figures 1 and 2 allows to separate and divide up to two different fluid fuels inside the tank (3). In fact, thanks to the use of the five-way valve (6), it is possible to introduce two different fuels (for example natural gas and LPG): the first fuel (for example LPG) can be stored inside the membrane (1) and a second fuel (for example natural gas) can be stored outside the membrane (1). Because the membrane (1) is elastic/flexible, it is possible to store two different types of fuel in any percentage: for example the user can decide to leave the inner part of the membrane (1) empty and to fill completely the external part of the membrane (1) or viceversa, the user can decide to fill completely the inner part of the membrane (1). In the latter case, the membrane (1), due to its elasticity/flexibility, will expand until it completely adheres to the inner edge of the tank (3). The device is designed to maintain the same static pressure inside and outside the membrane (1), so that said membrane (1) is not mechanically stressed beyond the resistance limits of the material of which it is made The balancing of internal and external pressures makes it possible to operate even at very high pressures without mechanical stresses on the membrane (1).

EXAMPLE 2

Working of the device of Figures 3 and 4

The device of Figures 3 and 4 allows to separate and divide up to two different fluid fuels inside the tank (3). In fact, thanks to the use of the three-way valve (4), it is possible to introduce a first type of fuel (for example natural gas) inside the membrane (1) and, thanks to the use of the three-way valve (5) it is possible to introduce a second type of fuel (for example LPG) inside the membrane (1). Because the membrane (1) is elastic/flexible, it is possible to store two different types of fuel in any percentage: for example the user can decide to leave the inner part of the membrane (1) empty and to fill completely the external part of the membrane (1) or viceversa, the user can decide to fill completely the inner part of the membrane (1). In the latter case, the membrane (1), due to its elasticity/flexibility, will expand until it completely adheres to the inner edge of the tank (3). The device is designed to maintain the same static pressure inside and outside the membrane (1), so that said membrane (1) is not mechanically stressed beyond the resistance limits of the material of which it is made The balancing of internal and external pressures makes it possible to operate even at very high pressures without mechanical stresses on the membrane (1).

EXAMPLE 3

Working of the device of Figure 5

The device of Figures 5 allows to separate and divide up to two different fluid fuels inside the tank (3) and the tank (15). In fact, thanks to the use of the three-way valve (4), it is possible to introduce a first type of fuel (for example natural gas) inside the tank (3) and, thanks to the use of the three-way valve (5), it is possible to introduce a second type of fuel (for example LPG) inside the tank (15). Since the tank (3) and the tank (15) have a predetermined volume, it is possible to store the two different types of fuel in a precise percentage: the quantity of fuel stored will depend on the dimensions of the two tanks (3 and 15). In this case, the fluid fuel storage pressure in the tank (3) may be different from the fluid fuel storage pressure in the tank (15).

EXAMPLE 4

Working of the device of Figure 6

The device of Figure 6 allows to separate and divide up to three different fluid fuels inside the tank (3). In fact: thanks to the use of the three-way valve (4), it is possible to introduce a first type of fuel outside the membrane (16);

thanks to the use of the five-way valve (13), it is possible to introduce a second type of fuel inside the membrane (1);

and thanks to the use of the five-way valve (13), it is possible to introduce a third type of fuel inside the membrane (16) and outside the membrane (1).

Because the membranes (1 and 16) are elastic/flexible, it is possible to store the three different types of fuel in any percentage. The device is designed to maintain the same static pressure inside and outside the membranes (1 and 16), so that said membranes (1 and 16) are not mechanically stressed beyond the resistance limits of the material of which they are made. The balancing of internal and external pressures makes it possible to operate even at very high pressures without mechanical stresses on the membranes (1 and 16).

EXAMPLE 5

Working of the device of Figures 7 and 8

The device of Figures 7 and 8 allows to separate and divide up to three different fluid fuels inside the tank (3). In fact:

thanks to the use of the three-way valve (4), it is possible to introduce a first type of fuel inside the tank (3);

thanks to the use of the five-way valve (6), it is possible to introduce a second type of fuel inside the membrane (1);

and thanks to the use of the five-way valve (6), it is possible to introduce a third type of fuel outside the membrane (1);

The amount of fuel introduced through the use of three-way valve (4), is predetermined: said quantity of fuel depends on the size of the tanks (3 and 15) and can be stored at a pressure different from the storage pressure of the other two fuels introduced with the use of the five-way valve (6).

Since the membrane (1) is elastic/flexible, it is possible to store the remaining two different types of fuel in any percentage. The device is designed to maintain the same static pressure inside and outside the membrane (1), so that said membrane (1) is not mechanically stressed beyond the resistance limits of the material of which it is made. The balancing of internal and external pressures makes it possible to operate even at very high pressures without mechanical stresses on the membrane (1).

EXAMPLE 6

Working of the device of Figures 11 and 12

The device of Figures 11 and 12 allows to separate and divide up to two types of different fluid substances inside the industrial tank (3). In fact, thanks to the use of the tap (18), it is possible to introduce a first type of fluid substance outside the membrane (1) and, thanks to the use of the tap (21), it is possible to introduce a second type of fluid substance inside the membrane (1). Since the membrane (1) is elastic/flexible, it is possible to store the remaining two different types of substances in any percentage. The device is designed to maintain the same static pressure inside and outside the membrane (1), so that said membrane (1) is not mechanically stressed beyond the resistance limits of the material of which it is made. The balancing of internal and external pressures makes it possible to operate even at very high pressures without mechanical stresses on the membrane (1). According to the type of fluids to be stored, of their physical state (gas, liquid, vapour and/or their mixtures) and to the storage pressure, the taps (18, 19, 20, 21) can be substituted by n- way inlet/outlet valves and/or safety valves. According to the type of fluids to be stored, of their physical state (gas, liquid, vapour and/or their mixtures) and to the storage pressure, n-way inlet/outlet valves, safety valves, overflow valves, additional taps, etc. can be added. If the taps (18, 19, 20, 21) are connected to pressurized pipes, the emptying or filling of the fluid inside the membrane (1) can be controlled by filling or emptying the fluid outside the membrane (1) and viceversa. For example, the introduction of fluid under pressure from the tap (18) would force, if allowed by the opening of the tap (20) and the back pressure of the pipe, the outlet of the fluid contained inside the membrane (1) through the tap (20). Similarly, the introduction of pressurized fluid from the tap (21) would force, if allowed by the opening of the tap (19) and the back pressure of the pipeline, the outlet of the fluid contained outside the membrane (1) through the tap (19). The device therefore allows, in addition to the storage of fluids, the possibility of supplying pressure circuits without the need to install pumps or compressors on each of the input/output circuits.

EXAMPLE 7

Working of the device of Figure 13

The membrane (1) is filled with a sparkling liquid. Each time the sparkling liquid is used/drunk, the device according to the present invention, ensures that the air never comes into contact with the sparkling liquid, confining said air outside the membrane (1). In this way the user can prevent said sparkling liquid from losing gas by coming into contact with the air.

EXAMPLE 8

Further exgmple of the working of the device of Figure 13

The membrane (1) is filled with a liquid (ex. drink or water, even non-sparkling). The membrane separates the liquid from the contact with the bottle (27). In this way the liquid never comes into contact with the bottle (27), which, when made of plastic material, could over time as a result of degradation release of phthalates which may not, however, contaminate the liquid which remains protected inside the membrane (1).
