Description

Technical Field

[0001] The present invention belongs to the field of liquid fuel purification devices, and particularly relates to a liquid fuel purifier using physical and electrochemical methods. Background Art

[0002] Various machines such as internal combustion engines or boilers use liquid fuels such as gasoline or diesel to operate. These machines require the fuel to reach a certain level of purity so that these machines can operate reliably at full power.

[0003] These fuels may be contaminated by different elements, such as water, silica, dirt, grit, etc.

[0004] These impurities can cause failures in the fuel systems of engines or machines. For example, a diesel internal combustion engine has a fuel system mainly composed of a low-pressure pump, a high-pressure pump, and an injector. These components are specifically designed to pump and inject diesel. These components utilize the lubricating properties of diesel to function, and their operating parameters are designed for the density of the fluid. In the case of diesel being contaminated by water, the mixture of diesel and water will lose the necessary lubricity and have a higher density, which may lead to failures of the pump or injector. In addition to being contaminated by water, if the fuel is also contaminated by dust, silica, or any solid element, then this situation is more likely to occur because these elements will damage the components listed above.

[0005] To solve these problems, a common practice in diesel engine engineering is to add a common cellulose filter and / or a centrifugal purifier between the low-pressure pump and the high-pressure pump. A common cellulose filter has a cellulose filter paper element with small holes having a diameter between 10 and 60 microns to prevent particles larger than these holes from passing through. In this way, when the fuel passes through, the filter retains most of the contaminants and allows the fuel with a lower impurity load to pass through.

[0006] On the other hand, there are centrifugal or decantation purifiers. These purifiers generally contain mechanisms that accelerate the fuel in a centrifugal manner, causing contaminants with a specific gravity greater than that of diesel or gasoline to be retained at the lower part of the purifier, while the fuel free of water, dirt, and other contaminants flows to the top of the purifier and then flows to the engine in a purified state.

[0007] Another factor to consider in fuels is their microbial content. This is mainly because gasoline and diesel are both organic compounds that are easily decomposed. In this sense, they rot over time. The reason for fuel spoilage is that aerobic and anaerobic bacteria feed on free radicals in hydrocarbon chains, sulfur and moisture in the fuel, and oxygen present in the fuel tank or storage tank. This phenomenon is widely described in the publication "Microbial Contamination of Stored Hydrocarbon Fuels and Its Control" by Christine C. Gaylarde, Fátima M. Bento, and Joan Kelley.

[0008] When the environment contains or has dirt, soil, pollutants, or water, fuel decomposition is accelerated. In this sense, the decanting filters and purifiers have areas that promote fuel spoilage. For example, in the case of filters, the filter paper element is filled with pollutants that remain in the area where bacteria form and in the interface formed between the fuel and the pollutants retained at the bottom (in the case of centrifugal purifiers, such as water, sediment, or land). Sometimes the engine is off and the fuel remains stagnant within these devices, which further promotes its spoilage.

[0009] This problem is very serious because the growth of bacteria in the fuel produces by-products such as acids, which have a very negative impact on the metal components of the engine. Also, the size of bacteria can range from less than 1 micron to 500 microns, so there is a range that cannot be filtered by the filter (less than 10 or 20 microns), while another range will favor premature saturation of the filter paper.

[0010] In this sense, the disadvantage of the mechanisms that purify fuel physically, specifically by centrifugation, is that when they are not replaced or cleaned, they contain a small mixture of fuel, pollutants, and dirt, which causes them to accelerate fuel spoilage, whether when the fuel flows through the mechanism during engine or machine operation, or when the engine or machine is off and the fuel is sealed with the pollutants in the mechanism.

[0011] An example of these technologies is the common type of centrifugal diesel purification product. You can refer to https: / / purifisagp.com / purificadores-decombustible / #!, which describes the operation of its product as follows: When the fuel enters the purifier, it flows through the tubular section in a turbulent manner to the bottom of the purifier. The fuel then strikes the deflector plate that divides the purifier into two symmetric regions and generates strong turbulence. When the engine pump needs fuel, the fuel flows upward through the purifier in a centrifugal manner, separating all solids and liquids heavier than the fuel. In addition, the sedimentation principle of solid particles and the density difference of liquids contribute to the separation.

[0012] Impurities accumulate at the bottom and remain there until they are cleaned; only the clean fuel rises to the top outlet of the purifier and reaches the engine, ready for faster ignition and better combustion.

[0013] It can be seen that the operation of the device means that an environment conducive to the growth of bacteria will be created inside it, mainly in its lower part, where pollutants are retained and come into contact with the fuel.

[0014] Similarly, there are electrochemical devices for the spontaneous elimination of bacteria in fuel, which are composed of alloys or materials mainly made of metals. When these materials are immersed in the fuel or in close contact with the fuel, they create a reducing environment that electrochemically attacks the cell walls of bacteria, preventing their proliferation and causing them to die and gradually disappear. This phenomenon is extensively described in the publication "Effect of Metal Alloy Fuel Catalysts on Bacterial Growth" by Ruma Ghosh, Claudia Koerting, Steven L. Suib, Michael H. Best, and Alvin J. Berlin.

[0015] These materials are actually used through impregnation devices immersed in the fuel in a fuel tank or storage tank or through cross-flow devices installed in a fuel hose. In both cases, the chemical materials and catalytic purification materials are contained within the device to ensure close contact between them.

[0016] Some examples of these technologies are: Patent US8298405B2 "Device and Method for Recovering and Regenerating Hydrocarbon Fuel", which details the incorporation of metallic lead and bismuth in smaller proportions, which are the preferred forms for achieving solids, nanostructures, or thin films; and Patent US6306185B1 "Method and Device for Treating Fuel", which proposes an alloy containing zinc, cerium, palladium, magnesium, and silver and describes a system in series with the fuel hose of an internal combustion engine injection system and a device designed to be installed inside a fuel tank, where the preferred form of the alloy is particles. Similarly, US Patent No. 5580359 describes a catalytic element system, the catalytic elements of which have a particulate or conical geometry contained in a container made of plastic or metallic material, are supported by a steel mesh, and are divided into multiple layers. In addition, Patent US2002139044 proposes another composition, which relates to a mixture of tin, antimony, zinc, and silver.

[0017] A proposal for improving the above device is the patent "Fluid Mechanical System for Optimizing the Operation of a Catalytic Alloy to Improve Performance and Eliminate Microbial Contaminants in Hydrocarbon Fuel", whose priority number is WO2017PE00003 (20170302), which describes the arrangement of catalytic alloy particles, the volume of which is less than 60 mm 3, tightly contained within a net, a housing, and a nitrile cap, and its application method is mainly fuel immersion. The described arrangement and geometry of the particles particularly increase the intensity of the sterilization treatment by up to three times compared to ordinary particles.

[0018] The disadvantage of these techniques is that they can only prevent the formation of bacteria and eliminate them, but have no effect on pollutants such as water or soil. On the contrary, the devices containing these immersed alloys may be covered by pollutants (water, dirt, sediment, etc.) due to being located at the bottom of the fuel tank and do not have any purification effect on the fuel. Similarly, the devices installed in the fuel pipeline also have the disadvantage that when fuel contaminated with particles, sediment, or dirt flows through these devices, these devices may be blocked. In addition, these devices have no effect on the water or soil content that may be present in the fuel.

[0019] After describing the state of the art, it is now possible to identify the technical problem as the fact that fuel purification devices using physical methods (mainly by decantation or centrifugation) promote the formation of microbial pollutants and thus promote the formation of acids under normal fuel operating conditions.

[0020] On the other hand, if the goal is to purify the fuel by chemical and physical means, different devices must be combined in different parts of the vehicle fuel system to produce this effect separately. In this sense, there is no compact and practical solution that is also easily compatible with the vehicle's fuel system for the chemical and physical purification of fuel.

[0021] In addition, another problem is that although there are solutions for removing microbial pollutants, these solutions are often set in the fuel pipeline or fuel tank and do not solve the problem of bacterial growth inside the fuel purifier.

[0022] Finally, in the prior art, it is impossible to find a solution that manages to integrate a chemical purification method (such as a catalytic fuel purification alloy) and a physical purification method (such as centrifugation or decantation purification method) in a single device that has no back pressure, is compact, and can be conveniently installed in the fuel system of a vehicle engine. Summary of the Invention

[0023] After describing the prior art and the related technical problems, a purifier for purifying liquid hydrocarbon fuels by physical and chemical means is proposed as a solution. The purifier has an apparatus for decanting contaminants inside and devices for chemically and spontaneously purifying the fuel, mainly for killing bacteria electrochemically. In this way, the system will be able to perform the following operations simultaneously in a single device that is easy to install in a common fuel system: separating contaminants such as water, particles, and sediments from the fuel, while inhibiting the growth of bacteria and removing these contaminants. Thus, the technical problems related to the fact that contaminants were left in the prior art, promoting the growth of bacteria and fuel spoilage, are overcome.

[0024] This purifier is characterized by its compact structure. To achieve the above object, the system includes a container that consists of a body and a lid, which are sealed together and contain a decanting and chemical purification mechanism inside. The container has means for allowing fuel to enter and exit its interior, such as hydraulic connectors, like external threaded joints.

[0025] The contaminant decanting mechanism must be physical, for example, by centrifugation, or by the impact of vanes or baffle plates or by deflection, and the latter method is the preferred method to be used.

[0026] The method of using the impact of vanes or baffle plates or by the deflection of the fuel stream (or the mixture of fuel and contaminants) is preferred because the vanes are arranged vertically, thus also preventing excessive movement of the fuel inside the purifier and guiding it to the top.

[0027] The container also has means for cleaning the contaminants at the bottom so that when the contaminants accumulate in the lower interior of the container, they can be discarded. For example, these means can be of the common type of cleaning valves.

[0028] The chemical purification medium mainly consists of alloy parts that spontaneously kill bacteria in the fuel. This can be implemented in different ways, such as in the form of particles, flakes, plates, etc. Examples of such alloys can be alloys of tin and antimony or silver, copper, and tin, etc.

[0029] To achieve the above growth inhibition effect, decanting must occur below the level of the bactericidal alloy parts used for chemical purification. It should be noted that this chemical purification mechanism must be exposed and in contact with the fuel, such that the sides of this mechanism face or are exposed to the inner bottom of the purifier. This is because the contaminants settle at the bottom during decanting. Usually, these contaminants do not mix with the fuel because they are insoluble in fuels such as diesel or gasoline, but form an interface. The region where the fuel and contaminants meet can be called the fuel - contaminant interface, and it is precisely in this region that bacteria grow most vigorously. Thus, since the chemical purification elements are above the level where decanting occurs and since they are exposed to the fuel, it is ensured that the growth of bacteria in the contaminated fuel interface can be inhibited due to chemical purification.

[0030] To obtain a greater fuel purification effect, in addition to inhibiting bacterial growth, fuel that is already free of solid or liquid contaminants must flow in a very close manner (from the side, through, or in close contact) to the alloy parts for chemical purification. Therefore, the fuel chemical purification system must be arranged behind the decantation mechanism and in front of the device that causes the fuel to flow outwards, so that the fuel necessarily flows close to the bactericidal alloy parts. Preferably, the fuel must be forced through these bactericidal alloy parts. The bactericidal alloy parts can be arranged immediately in front of the fuel outlet, or there can be a gap between the two, or the bactericidal alloy parts can be arranged in the inner middle part of the purifier. These bactericidal alloy parts can be a structural part of the purifier, or they can be contained within plates, meshes, or other devices that allow them to come into contact with the fuel. It is recommended that these catalytic alloy parts have a small size to increase their surface area in contact with the fuel. Since the catalytic alloy parts are located in the middle of the purifier or close to the fuel outlet, it promotes the fuel to be as pure as possible when leaving the purifier, both in terms of solid elements and microbial elements.

[0031] Returning to the physical decantation aspect and delving into the details of the hydrodynamic system of the proposed purifier, the interior of the purifier must include a decantation mechanism, which is preferably a decantation mechanism that operates due to stagnant flow. The characteristic of this mechanism is that it has a plurality of deflection plates. To produce decantation, the flow of the contaminated fuel must be directed towards these deflection plates, so that when the fuel collides with them, due to the different densities, solids and water will tend to flow towards the lower part of the purifier, while the purified fuel will flow upwards.

[0032] To enhance the decantation effect caused by deflection and stagnant flow, the contaminated fuel must be directed towards the deflection plates immediately after entering the purifier body, in order to make better use of the kinetic energy of the fluid. In addition to improving the decantation of contaminants, immediately directing the fuel towards the deflection plates and the consequent better utilization of kinetic energy means that the pressure loss is much lower, which is very beneficial for the operation of the fuel system.

[0033] Decanting contaminants from the fuel is beneficial because the entry of the fuel into the body represents a throttling device, which allows the speed of the fuel to increase and the impact on the deflection plates to be stronger. This device can be a nozzle, which can be part of the purifier body itself to make it as compact as possible.

[0034] Another characteristic of the design proposed for this stagnant flow mechanism is that it has a main deflection plate, which is located in front of the fuel inlet of the purifier body and has parallel channels at the height of the purifier, so that the jet of the mixture of fluid and solids entering the purifier is split and guided, thus promoting decantation.

[0035] In addition, the present design has a secondary deflector plate which is located in front of the main stagnation plate and preferably at the height of the fuel inlet or nozzle. In this way, a second shock is generated very close to where the first shock occurs, so that contaminants are directed to the bottom of the decanter.

[0036] Another advantage of this design is that it has a plurality of auxiliary deflector plates which are also parallel to the height of the purifier and generate a strong stagnation effect, preventing the fuel from remixing with the contaminants it carries and significantly limiting the displacement of the fuel-contaminant interface, which is beneficial to the inhibitory effect of the bactericidal alloy parts. If the interface is in constant agitation and movement, the inhibitory effect will be hindered.

[0037] It is also proposed that all the plates be connected at their upper parts by a vertical base so that they are joined into a single decanting element. The base has such a geometry that its maximum diameter is limited externally by the inner diameter of the purifier body, so that the base can fit sealingly within the body and thus be held in place. Similarly, the base has holes, grids or free spaces in the areas without deflector plates or stagnation plates, so that the fuel can flow to the upper part of the purifier and then through the bactericidal alloy parts.

[0038] In this stagnation element, there should be a significantly larger plate extending from one end of the purifier to the other, preferably in the middle and longer than the auxiliary deflector plates, thus forming a plate that acts as a main breakwater or sealing partition. This further prevents the movement of the fuel and the fuel-contaminant interface.

[0039] One design criterion to be considered is that there must be a larger number of deflector plates or stagnation plates on the side of the stagnation plate where the fuel inlet is located, because this side will be the area where there is more agitation of the fluid. On the opposite side, there must be a much smaller number of auxiliary plates rather than a large number of plates in order to have more free space to allow the fuel to flow to the catalytic alloy parts.

[0040] In this way, it is possible to produce the technical advantages of a fuel purification device that retains liquid and solid contaminants, prevents bacterial formation and purifies them, which is compact, does not generate backpressure on the fuel flow and is easily installed in the fuel system of a gasoline or diesel engine.

[0114] Although the present invention can be implemented in many different ways as shown in the drawings, and the preferred embodiments of the present invention will be described in detail below, it should be understood that the disclosed content should be regarded as an example of the principles of the present invention and is not intended to limit the broad aspects of the present invention to the examples shown.

[0115] The fuel purifier has a body 1 at its middle and a nozzle 8 in the tangential direction. The nozzle 8 starts from the outside of the body 1 and terminates inside the body 1. The nozzle 8 has a through hole so that fuel can flow from the outside to the inside. The nozzle 8 has the shape of a female connector for hydraulic connection on its outside, so that the inlet connector 3 can be connected. The inlet connector 3 can be, for example, an external thread joint to connect the purifier to the fuel discharge hose of the fuel system from the engine. The cross-section of the through hole of the nozzle 8 decreases as it gets closer to the inside of the purifier body 1, thus causing a throttling effect when the fuel enters the inside of the purifier, resulting in an increase in its speed.

[0116] The body 1 has a cleaning valve 5 at its lower part. The cleaning valve 5 is used to clean the impurities remaining in the purifier after the purified fuel passes through the purifier.

[0117] The deflection decanting element 9 has a base 18 with different vertical plates. Among these plates, there is a main deflection plate 13, which is located at one end of the base and has a main deflection plate channel 17 on one of the faces. A secondary deflection plate 14 is opposite the main deflection plate 13 and slightly offset to the center of the base 18. The secondary deflection plate is also parallel to the main deflection plate 13. In the middle of the base 18 there is a sealing partition 16 extending from one end to the other. Finally, there are auxiliary deflection plates 15 on both sides of the sealing partition. For example, there can be two auxiliary deflection plates 15 next to the secondary deflection plate and one auxiliary deflection plate 15 at the other end of the sealing partition 16.

[0118] The geometry of the base 18 of the deflecting decantation element 9 is such that it does not completely cover or divide the interior of the body 1 , but leaves free space allowing the fuel to flow to the upper part.

[0119] The deflection decantation element 9 is fixedly mounted in the body of the purifier, with its base 18 resting on the nozzle 8 of the body and perpendicular to the inner wall of the body 1 and matching its diameter. In addition, the main deflector 13 should face the discharge side of the body nozzle 8, and all the deflectors should face the bottom of the purifier. The deflection decantation element 9 can be fixed using epoxy resin glue or other fuel-resistant glue.

[0120] On the base 18 of the deflecting decantation element, a lower container plate 11 is mounted, which has means allowing the fuel to flow, such as small holes or a grid.

[0121] The sterilization alloy piece 10 is placed on the lower container plate 11, and the lower container plate 11 will be contained and compacted by the upper container plate 12 which also has small holes or meshes.

[0122] The bactericidal alloy 10 may be, for example, an alloy of copper, antimony and bismuth. In addition, these bactericidal alloys 10 should preferably be particles having a circular geometry, a disk shape or an irregular shape similar to the foregoing two, and a volume greater than 30 mm 3 And less than 140mm 3 . It is recommended that the bactericidal alloy pieces 10 adopt this volume and geometry because this will enable them to be compacted between the lower container plate 11 and the upper container plate 12, thereby being able to form a space between them that promotes the flow of fuel towards the upper part of the purifier and provides an effective and efficient treatment for the elimination of microbial contaminants. In addition, the proposed geometry and volume will reduce the overall weight of the bactericidal alloy pieces 10 used and make it easier for contaminants to be retained by the grid or net, wherein the openings of the grid or net are of a size that allows the fuel to pass freely. These factors help to reduce the back pressure that may be generated inside the purifier.

[0123] The two plates 11 and 12 may be fixed using some epoxy glue or other fuel resistant glue.

[0124] After installing the internal components within the main body 1, the cover 2 is placed over the upper portion of the main body 1 and secured by bolts 6 and nuts 7 such that the junction between the main body 1 and the cover 2 is sealed. An O-ring or sealant may be used to enhance the sealing.

[0125] Finally, the cover 2 has a hole to allow the installation of the outlet connector 4, thereby connecting the purifier to the fuel system.

[0126] The purifier should be installed in the fuel system of an engine, such as in the fuel system of a diesel engine, preferably behind the low-pressure pump and in front of the high-pressure pump.

[0127] In this way, the contaminated fuel is driven by the low-pressure pump from the fuel tank and flows through the hose until it enters the inlet connector 3 and passes through the main body nozzle 8, where it is throttled, increasing its velocity and shooting towards the main deflector plate 13, where it collides with the main deflector plate channel 17 and causes the heavier elements, mainly composed of liquid and solid contaminants, to tend to move towards the bottom of the purifier, while the lighter elements, mainly composed of fuel, tend to move towards the top of the purifier.

[0128] Then, the contaminants and fuel collide with the secondary deflector plate 14, such that the separation of the contaminants from the fuel is amplified. Additionally, after the mixture of fuel and contaminants collides with the main deflector plate 13 and the secondary deflector plate 14, the fuel will collide with other auxiliary deflector plates 15 and finally separate.

[0129] The sealing partition 16 prevents the fuel from sloshing out due to vehicle movement during rapid acceleration and deceleration of the vehicle, and helps to prevent the fuel from mixing with the contaminants or the contaminants from reaching the top of the purifier in the case of sudden braking of the vehicle.

[0130] Figure 5 Shows how, when fuel mixed with contaminants enters through the inlet connector 3, it will pass through the main body nozzle 8, be throttled and directed towards the main deflector plate 13 and its channel 17, then towards the secondary deflector plate 14, and subsequently collide with the auxiliary deflector plate 15 at a much lower velocity, where the contaminants are directed towards the lower part of the purifier, while the fuel will be directed towards the upper part, passing through the lower container plate 11 and then through the sterilizing alloy member 10.

[0131] Figure 6 Shows the mechanism that causes the liquid and solid contaminants to reach the lower part of the purifier after colliding with the different plates of the deflection segregation element 9, and causes the purified fuel to flow towards the top, be purified through the sterilizing alloy member 10, and then leave the purifier.

[0132] All the plates 13, 14, 15 and 16 also help to prevent the re-mixing of the fuel and the contaminants, which is achieved by restricting the movement of the fuel and directing its flow vertically towards the top of the purifier.

[0133] Fuel that has been freed of liquid and solid contaminants (water, dirt, particles, etc.) flows through the free space between the base 18 and the inner wall of the main body 1, passes through the lower container plate 11, and passes through the bactericidal alloy member 10, where microbial contaminants are killed. The fuel then continues to flow to the top of the purifier, passes through the upper container plate 12, and finally exits through the outlet connector 4 and continues through the fuel hose of the engine fuel system to the high-pressure pump.

[0134] When the engine is off and the fuel is not flowing, and the fuel is sealed within the decanter, the bactericidal alloy member 10 - which is exposed to the lower part of the purifier through the space formed between the base 18 and the inner wall of the main body 1 and the grid or holes of the lower container plate 12 - inhibits the growth of bacteria in the interface formed between the clean fuel and the contaminants contained in the lower part of the purifier.

[0135] Finally, the contaminants must be periodically cleaned by opening the cleaning valve 5 so that the interior of the purifier does not become saturated with contaminants.
