The apparatus mixes diesel and bio-oil in a nanosized state such as that of microbubbles, and supplies the mixture directly to a marine engine in real time for combustion, thereby not only dramatically enhancing combustion efficiency solely through physical treatment without the addition of an emulsifier, but also substantially reducing the generation of harmful substances during the combustion process.

Description

Device for manufacturing mixed fuel of diesel and bio-oil and management system thereof

[0001] The present invention relates to a device for manufacturing a mixed fuel of diesel and bio-oil and a management system thereof. More specifically, it relates to a device for manufacturing a mixed fuel of diesel and bio-oil and a management system thereof that can prevent layer separation without the addition of an emulsifier, significantly improve combustion efficiency, and greatly reduce the emission of air pollutants by continuously passing bio-oil—which is relatively inexpensive as marine fuel oil—through a high-speed mixing, dispersion, and emulsification treatment process together with diesel and supplying it directly to a marine engine for ignition.

[0002] Diesel is a type of petroleum obtained by the fractional distillation of crude oil. It is a mixture of hydrocarbons separated at boiling points between 250 and 350°C and is the substance separated after kerosene in distillation towers used in refineries. The name "diesel" was given because its density is lower than that of heavy oil, but it is denser than gasoline, naphtha, and kerosene.

[0003] Emulsion fuel oil is typically manufactured by mixing diesel fuel with bio-oil, a waste fuel resource, in an appropriate ratio, adding a suitable amount of emulsifying additive, and stirring to prevent oil-water separation. It is known that during combustion, the instantaneous evaporation and expansion of the dispersed diesel fuel atomizes fuels such as heavy oil, thereby promoting complete combustion and reducing the generation of particulate matter and carbon monoxide. Additionally, the formation of nitrogen oxides is suppressed due to the low air-fuel ratio and combustion gas temperature.

[0004] In the process of manufacturing emulsified fuel oil, the most important aspect is the primary stirring step using an agitator while adding emulsifying additives to prevent oil-water separation between the bio-oil and diesel fuel constituting the blend.

[0005] To solve these problems, prior published patent No. 10-2015-0140082, "System and Method for Manufacturing Alternative Emulsified Fuel," discloses a system and method for manufacturing alternative emulsified fuel that can more efficiently produce emulsified fuel by effectively stirring fuel such as bio-oil, including a stirrer in which a rotating plate and a fixed plate are alternately installed so that the fuel and the emulsified aqueous solution are evenly stirred and mixed; however, the current situation is that the dispersion emulsification is insufficient due to the high viscosity.

[0006] Recently, as international oil prices rise and there is a demand for improved ship efficiency to meet EEXI and CII standards, shipping companies face an urgent need for CO2 reduction. To address this, research is actively underway to blend biofuels into marine fuel at a certain ratio; however, in the case of blended fuels, changes in temperature can cause phase separation or the formation of microcrystals, which can lead to engine failures or fuel filter clogging.

[0007] Meanwhile, a biofuel blending system refers to a device that supplies biofuel by blending it in real-time on board the vessel into marine gas oil (MGO) used in fuel tanks. It is a system that applies dispersion technology to enable the use of biofuel as an eco-friendly fuel satisfying the international community's carbon neutrality requirements, but its efficiency and safety must be verified for use in ship engines.

[0008] The inventors discovered that by mixing bio-oil in a nano-sized state, such as microbubbles, and supplying it directly to a ship engine in real time for combustion, combustion efficiency can be dramatically improved and the generation of harmful substances reduced through physical treatment alone without the addition of emulsifiers, and thus completed the present invention.

[0013] The present invention aims to solve the above-mentioned problems by providing a device for manufacturing a mixed fuel of diesel and bio-oil and a management system thereof, which processes bio-oil into a nano-sized state similar to diesel oil and supplies it directly to a ship engine for ignition.

[0014] However, the objectives of the present invention are not limited to those mentioned above, and other unmentioned objectives will be clearly understood by those skilled in the art from the description below.

[0015] To achieve the above objective, a mixed fuel manufacturing apparatus for diesel and bio-oil according to an embodiment of the present invention comprises: a diesel tank (10) that supplies diesel through a diesel pump (1a); and

[0016] A one-pass dispersion emulsifier (40) that allows for the combustion of bio-oil, which is relatively inexpensive as marine fuel oil, by supplying it from a bio-oil tank (30) through a bio-plant fiber pump (1b) and continuously high-speed mixing and dispersing it together with diesel fuel, and then supplying it directly to a marine engine for ignition to dramatically improve combustion efficiency, thereby supplying it directly to a marine engine for combustion without the need for an emulsifier;

[0017] The one-pass dispersion emulsifier (40) is a device for producing mixed fuel of diesel and bio-oil, characterized by being configured in a cylinder shape with a multi-stage configuration of a stator and a rotor while bio-oil and diesel are provided, mixing them to produce nano-sized marine fuel oil, supplying it to a mixed fuel tank (50), and then using it directly as marine fuel oil for a marine engine through a boost pump (50a).

[0018] At this time, a device for manufacturing a mixed fuel of diesel and bio-oil can be provided, further comprising an air dispersion emulsifier device (10a) that improves mixing efficiency when bio-oil and diesel are mixed by inhaling air into the diesel oil and nano-sizing the bubbles so that the nano-sized bubbles containing oxygen exist in a dispersed state within the diesel oil corresponding to the liquid, and sending the liquid in this state to a one-pass dispersion emulsifier (40) that mixes and sprays bio-oil and diesel oil in the next stage.

[0019] In addition, the one-pass dispersion emulsifier (40) is,

[0020] A device for manufacturing a mixed fuel of diesel and bio-oil can be provided, characterized by continuously mixing the supplied diesel fuel to form nano-sized bubbles and then immediately supplying it to a ship engine for ignition, thereby dramatically improving combustion efficiency and enabling combustion by supplying it directly to a ship engine without the need for an emulsifier.

[0021] Additionally, a control panel (60) that performs monitoring of the marine fuel oil supplied to the marine engine by measuring the fuel flow rate inside the mixed fuel tank (50) equipped with a fuel flow meter for measuring the fuel flow rate of the marine fuel oil generated in the one-pass dispersion emulsifier (40) may be provided.

[0022] In addition, the control panel (60) is,

[0023] A device for manufacturing a mixed fuel of diesel and bio-oil can be provided, characterized by controlling a temperature controller provided inside a one-pass dispersed emulsifier (40) to maintain the fuel temperature inside the one-pass dispersed emulsifier (40) at a preset temperature, calculating the cumulative flow rate before and after a one-hour test for each load corresponding to a ship engine, calculating the final fuel flow rate, and calculating the fuel reduction rate.

[0024] Also, the boost pump (50a) is,

[0025] A device for producing a mixed fuel of diesel and bio-oil can be provided, characterized by supplying marine fuel oil from inside a mixed fuel tank (50) to a marine engine under the control of a control panel (60).

[0026] To achieve the above objective, a management system for a mixed fuel manufacturing device for diesel and bio-oil according to an embodiment of the present invention comprises a one-pass dispersion emulsifier (40) that, when bio-oil and diesel are provided, is configured in a cylinder shape with a multi-stage configuration of a stator and a rotor to produce a nano-sized marine fuel oil, supplies it to a mixed fuel tank (50), and then allows it to be directly utilized as marine fuel oil in a marine engine through a boost pump (50a); The system is characterized by including a management server (300) that receives information regarding each constituent material, the composition ratio of the constituent material, and the rotational speed for mixing the rotor (140) through a network (200) via a control panel (60) to build a big data server for the mixing ratio of diesel and bio-oil according to the rotational speed for mixing the at least constituent material mixed in the diesel and bio-oil mixing fuel manufacturing device (100) of the diesel and bio-oil mixing fuel manufacturing device (100).

[0027] The present invention has the effect of preventing layer separation without the addition of an emulsifier and significantly improving combustion efficiency by passing bio-oil through a high-speed mixing, dispersion, and emulsification treatment process continuously, like diesel fuel, to mix it in a nano-sized state containing microbubbles, and supplying it directly to a ship engine in real time for combustion.

[0028] In addition, the present invention has the effect of promoting combustion and significantly reducing the emission of air pollutants generated during the combustion process.

[0034] Figures 6 and 7 are the results of a real engine test that passed through a Megalodon (product of Revolox Co., Ltd.), which is a marine fuel oil dispersion emulsification treatment device (100).

[0035] Hereinafter, a detailed description of preferred embodiments of the present invention will be given with reference to the accompanying drawings. In describing the present invention below, detailed descriptions of related known functions or configurations will be omitted if it is determined that such detailed descriptions could unnecessarily obscure the essence of the invention.

[0036] In this specification, when one component 'transmits' data or a signal to another component, it means that the component may transmit said data or the signal directly to the other component, or transmit said data or the signal to the other component through at least one other component.

[0037] The present invention is intended to provide a device for manufacturing a mixed fuel of diesel and bio-oil and a management system thereof, for mixing bio-oil into a nano-sized state like diesel oil and processing it to be supplied directly to a ship engine for ignition.

[0038] In this invention, the term "bio-oil" is used in a broad sense, including bio-vegetable oils obtained from natural animals and plants, as well as eco-friendly biodiesel made from waste cooking oil.

[0039] FIG. 1 is a drawing showing a mixed fuel manufacturing apparatus (100) of diesel and bio-oil according to an embodiment of the present invention. Referring to FIG. 1, the mixed fuel manufacturing apparatus (100) of diesel and bio-oil may include a diesel tank (10), a dosing tank (20), a one-pass dispersion emulsifier (40), a mixed fuel tank (50), a boost pump (50a), and a control panel (60).

[0040] The dosing tank (20) can receive diesel fuel through the diesel fuel tank (10) in a state where it has been processed by the air dispersion emulsifier device (10a) and supply it to the one-pass dispersion emulsifier (40).

[0041] In other words, in the conventional method of dispersing bio-oil for use as ship fuel, diesel fuel was mixed in a predetermined ratio to lower the viscosity of the bio-oil, increase combustion efficiency, and increase the amount of fuel, and an emulsifier was used in a chemical manner to prevent layer separation. However, in the present invention, the bio-oil is mixed with diesel fuel through a one-pass dispersing emulsifier (40) rather than a chemical method, and supplied directly to the ship engine in a nano-sized state, such as bubbles, to ignite it, thereby improving "thermal efficiency."

[0042] Accordingly, referring to FIGS. 1 and 2, the one-pass dispersion emulsifier (40) can produce nano-sized marine fuel oil by mixing bio-oil and diesel oil through a multi-stage configuration of a stator and a rotor while they are provided, supplying it to a mixed fuel tank (50), and then allowing it to be used directly as marine fuel oil in a marine engine through a boost pump (50a).

[0043] The marine fuel oil, which is fuel that has passed through the one-pass dispersion emulsifier (40), is fuel that has been processed from existing fuel in real time. The control panel (60) can monitor the marine fuel oil supplied to the marine engine by measuring the fuel flow rate inside the mixed fuel tank (50), which is equipped with a fuel flow meter for measuring the fuel flow rate of the marine fuel oil generated in the one-pass dispersion emulsifier (40). Here, the fuel flow meter is a mass flow meter, and can measure and record the cumulative weight of the supply flow rate and return flow rate for one hour.

[0044] According to an embodiment of the present invention, as shown in FIG. 4, the air dispersion emulsifier device (10a) may further include a housing having an air dispersion inlet (131a) and a liquid dispersion medium inlet (131b) formed on one side and a mixed fluid outlet (131c) formed on the other side, a suction rotor disposed adjacent to the inlets (131a) (132b) inside the housing, a rotor / stator installed close to each other and spaced apart from the suction rotor, and a motor that drives the suction rotor and the rotor / stator together.

[0045] This air dispersion emulsifier device (10a) draws air into the diesel fuel and nano-sizes the bubbles so that the nano-sized bubbles containing oxygen exist in a dispersed state within the diesel fuel corresponding to the liquid, and sends the liquid in this state to the next stage, a one-pass dispersion emulsifier (40) that mixes and sprays bio-oil and diesel fuel, so that when the bio-oil and diesel fuel are mixed, the nano-sized bubbles increase the oxygen supply and can dramatically improve thermal efficiency.

[0046] Accordingly, relatively inexpensive bio-oil is supplied from the bio-oil tank (30) as ship fuel, and is continuously mixed and dispersed at high speed together with diesel fuel and supplied directly to the ship engine for ignition, thereby significantly improving combustion efficiency. This is made possible by supplying directly to the ship engine for combustion without the need for an emulsifier.

[0047] That is, by continuously mixing the supplied diesel fuel to form nano-sized bubbles and then immediately supplying it to a ship engine for ignition, combustion efficiency can be dramatically improved and it can be supplied directly to the ship engine for combustion without the need for an emulsifier.

[0048] Additionally, the control panel (60) can control the temperature controller provided inside the one-pass dispersion emulsifier (40) to maintain the fuel temperature inside the one-pass dispersion emulsifier (40) at a preset temperature (e.g., 105 ℃ ± 5 ℃), calculate the cumulative flow rate before and after a one-hour test for each load corresponding to the ship engine, calculate the final fuel flow rate, and calculate the fuel reduction rate.

[0049] The boost pump (50a) can supply marine fuel oil from inside the mixed fuel tank (50) to the marine engine under the control of the control panel (60).

[0050] Fig. 2 is a drawing for explaining the structure of a one-pass dispersion emulsifier (40) in a mixed fuel manufacturing apparatus (100) of diesel and bio-oil according to an embodiment of the present invention. Referring to Fig. 2, in the one-pass dispersion emulsifier (40), a chamber (110) and a motor (130) are installed on a frame (160). The frame (160) is fixed by a shaft cover (161) so that the chamber (110) faces downward, and the motor (130) is fixed by a fixing bracket (162) so that it is positioned at the top of the shaft cover (161).

[0051] A coupling (132) connecting the shaft (131) of the motor (130) and the shaft (120) protruding from the top of the chamber (110) is installed within the shaft cover (161). The motor (130) or other components may be covered by a protective cover (163).

[0052] At the bottom of the chamber (110), an inlet (111) is provided for introducing diesel fuel and bio-oil, which are the objects to be dispersed and emulsified, and at one end of the side of the chamber (110), an outlet (112) is provided for discharging the objects to be dispersed and emulsified after the dispersion and emulsification is completed.

[0053] The input port (111) is connected to an input line (10a) to supply a dispersed emulsion target, and the discharge port (112) is connected to a discharge line to supply the dispersed emulsion target, which has undergone dispersion or emulsification within the chamber (110), to an external storage tank, etc.

[0054] In the inlet port (111), the discharge pressure of the dispersed emulsion target can be maintained through the discharge port (112) as the dispersed emulsion target is supplied through the inlet line (10a) by the operation of an externally installed pump.

[0055] That is, as the shaft (120) is installed vertically in the chamber (110), the rotor (140) can be installed so as to be arranged vertically, and the stator (150) can be fixed so as to be stacked vertically.

[0056] The chamber (110) provides a stacking space for stacking stators (150). A cover (114) for opening and closing the interior of the chamber (110) is installed on the bottom surface of the chamber (110), and the cover (114) is joined by bolts (115) to support the stators (150).

[0057] Since the interior of the chamber (110) can be opened and closed by the cover (114), in the event of a failure of the rotor (140) or stator (150), the bolt (115) can be loosened to remove the cover (114), and then the rotor (140) or stator (150) installed inside the chamber (110) can be replaced.

[0058] The shaft (120) is rotatably installed inside the chamber (110) and is installed to penetrate the chamber (110) and is connected to the shaft (131) of the motor (130) by a coupling (132). It is preferable to install the shaft (120) in the chamber (110) or the frame (160) via a bearing so that it can rotate smoothly within the chamber (110). Additionally, an O-ring or the like may be installed at the connection point with the chamber (110) to maintain the airtightness of the chamber (110).

[0059] The motor (130) is installed on the frame (160) to rotate the shaft (120). The rotational speed of the shaft (120) can be controlled by adjusting the rotational speed of the motor (130) through the operation of a control panel (60) installed on the frame (160) or outside thereof. A cap (121) is attached to one end of the shaft (120) to prevent the rotor (140) from coming off.

[0060] The impeller installed inside the chamber (110) is composed of a combination of a fixed-wing stator (150) and a rotating-wing rotor (140), and by axially arranging the fixed-wing stator (150) and the rotating-wing rotor (140) in multiple layers along the longitudinal direction of the shaft (120), it is possible to mix relatively inexpensive bio-oil and diesel oil in a nano-sized state like bubbles and supply them directly to the ship engine for ignition.

[0061] Specifically, the stator (150) is formed in a circular shape that fits inside the chamber (110) and is axially mounted in multiple layers on a shaft (120) that is rotatably installed inside the chamber (110) of the one-pass dispersion emulsifier (40).

[0062] These stators (150) have the uppermost stator (150) and the lowermost stator (150) fixedly installed by the end of the chamber (110) or other fixing means, so that they remain fixed when the shaft (120) rotates.

[0063] The stator (150) has a perforated inlet for the dispersed emulsion target so that the dispersed emulsion target can be introduced into the center. Accordingly, the dispersed emulsion target introduced into the chamber (110) can be introduced into the interior of the stator (150), which forms multiple layers, through the dispersed emulsion target inlet.

[0064] As a result, through the multilayer structure of the stator (150) and rotor (140), the efficiency of dispersion emulsion for the dispersion emulsion target is excellent, and low-viscosity dispersion emulsion target as well as high-viscosity dispersion emulsion target with low fluidity, such as bio-oil and diesel oil, are mixed in a nano-sized state like bubbles according to a preset ratio and supplied directly to the ship engine for ignition, thereby improving "thermal efficiency."

[0065] In other words, by a one-pass multi-layer structure, high-viscosity bio-oil is mixed evenly with diesel oil to overcome the limitations of supplying bio-oil and diesel oil mixed with an emulsifier. A stator equipped with a fixed shear projection and a rotor equipped with a rotating shear projection are combined in multiple layers on a shaft installed to rotate inside the chamber. By applying shear force to the dispersed emulsion target introduced while the rotating shear projection rotates relative to the fixed shear projection that does not rotate and the shaft rotates, the efficiency of dispersion emulsion for the dispersed emulsion target is improved, and not only low-viscosity dispersed emulsion targets but also high-viscosity dispersed emulsion targets with low fluidity can be processed.

[0066] In addition, the desired dispersion effect can be obtained simply by the dispersion target passing through the path once, and because high-speed dispersion is intensively performed on the dispersion target that is forcibly pumped into the chamber by a pump, low-viscosity dispersion target and high-viscosity dispersion target with low fluidity can be dispersed into micron-level as well as nano-level.

[0067] In another embodiment of the present invention, the control panel (60) can control the fan of the collector when the bio-oil-based marine fuel oil, which is broken down into nanoparticles and generated like bubbles by a structure in which the stator (150) and the rotor (140) are formed in a plurality of pairs, is additionally configured with a fan-type collector. To this end, the collector may be formed at the discharge port (112).

[0068] FIG. 3 is a diagram showing a management system (1) for a mixed fuel manufacturing device of diesel and bio-oil according to an embodiment of the present invention. Referring to FIG. 3, the management system (1) for a mixed fuel manufacturing device of diesel and bio-oil may include a plurality of mixed fuel manufacturing devices (100) of diesel and bio-oil, a network (200), a management server (300), and a plurality of administrator terminals (400).

[0069] The management server (300) can receive information regarding each constituent material, the composition ratio of the constituent material, and the rotational speed for mixing the rotor (140) through the network (200) via the control panel (60) to build a big data server regarding the mixing ratio of diesel and bio-oil according to the rotational speed for mixing the at least constituent material mixed in the diesel and bio-oil mixing fuel manufacturing device (100) for the diesel and bio-oil mixing fuel manufacturing device (100).

[0070] Additionally, the management server (300) can receive, via the network (200), from a manager terminal (400) operated by a manager who has investigated each constituent material, the composition ratio of the constituent materials, and the mixing ratio of the constituent materials that matches the rotation speed.

[0071] Accordingly, the management server (300) can build a big data server that accumulates information on each constituent material, the composition ratio of the constituent materials, the rotational speed for mixing with the rotor (140), and the mixing rate as a single sensing unit data.

[0072] Afterwards, the management server (300) can, in response to a request for a mixing ratio according to each constituent and the composition ratio of the constituents by the control panel (60) of the diesel and bio-oil mixing fuel manufacturing device (100), first extract the same or most similar composition ratio among the composition ratios of constituents corresponding to each constituent from the sensing unit data, then secondarily extract information on the rotational speed corresponding to the extracted same or most similar composition ratio, and then provide it to the control panel (60) of the diesel and bio-oil mixing fuel manufacturing device (100) through the network (200) to induce the mixing of constituents by the same or most similar mixing ratio.

[0073] And FIG. 5 is a drawing showing another embodiment of the one-pass dispersion emulsifier (40) in the mixed fuel manufacturing apparatus (100) of FIG. 2. In FIG. 5, the one-pass dispersion processor (40) may have other components of the one-pass dispersion processor (40) of FIG. 2 applied in the same way, and additionally, a cooling water inlet (111a) and a cooling water outlet (112a) may be added.

[0074] The cooling water inlet (111a) wraps around the outside of the multi-stage configuration layer of the stator and rotor inside the frame of the one-pass distribution processor (40) to form a cooling water jacket, thereby preventing overall overheating due to the cooling water, and allows the cooling water that has performed cooling to be discharged to the outside through the cooling water outlet (112a).

[0075] A demonstration experiment was conducted according to an embodiment of the present invention. As a result, a comparative experiment was performed with untreated Bunker C oil for a real engine test, which passed through Megalodon (product of Revolox Co., Ltd.), a marine fuel oil dispersion emulsification treatment device (100) shown in FIGS. 6 and 7. For the comparative experiment, three types of fuels—conventional fuel oil (Bunker-C), homogenized oil (MEGALODON), and 4% emulsion oil (Emulsion)—were tested at 50% and 75% loads, respectively. As a result of analyzing the combustion state at 50% engine load, it was confirmed that the Bunker and homogenized oils combusted well with little difference, and at 75% engine load, the combustion state was improved compared to Bunker oil.

[0076] The present invention can also be implemented as computer-readable code on a computer-readable recording medium. A computer-readable recording medium includes all types of recording devices in which data that can be read by a computer system is stored.

[0077] Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage devices, and also include those implemented in the form of carrier waves (e.g., transmission over the Internet).

[0078] In addition, computer-readable recording media are distributed across networked computer systems, allowing computer-readable code to be stored and executed in a distributed manner. Furthermore, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers in the technical field to which the present invention belongs.

[0079] As described above, preferred embodiments of the present invention have been disclosed in this specification and drawings. Although specific terms have been used, they are used merely in a general sense to facilitate the explanation of the technical content of the invention and to aid in understanding the invention, and are not intended to limit the scope of the invention. It is obvious to those skilled in the art that, in addition to the embodiments disclosed herein, other variations based on the technical concept of the present invention may be implemented.
