Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The key to a combustion device that mixes fuel and air to burn is to improve combustion efficiency in pursuit of complete combustion and to reduce harmful components in exhaust gas according to improvement in combustion efficiency. The improvement of the combustion efficiency of a combustion device depends on the quality of the air and fuel injected into the combustion device. The quality of fuel has been increased to a certain level due to the development of technology. Therefore, improving the quality of the air mixed into the combustion device is a problem to be solved.

The air supplied to the combustion device contains various harmful impurities including dust. An air cleaner is generally used to remove harmful impurities in the air mixed into the combustion device. Paper, non-woven fabric and synthetic resin are mainly applied as the material of the filter media used in the air cleaner.

The present invention provides a method for preparing a liquid composition for physically and chemically treating a filter medium in order to improve the performance of the air cleaner to improve the quality of air mixed into a combustion device, and a composition thereof.

1 is a flowchart for explaining an embodiment of a method for manufacturing a liquid composition for a filter medium of the present invention.

As shown in FIG. 1 , the method for manufacturing the liquid composition for a filter media of the present invention includes the steps of preparing a plurality of liquid metal nano-colloids and at least one liquid mineral nano-colloids (S100); accommodating the plurality of liquid metal nano-colloids and at least one liquid mineral nano-colloids in a predetermined container (S110); agitating a plurality of liquid metal nano colloids and at least one liquid mineral nano colloid in the container to generate a liquid synthetic colloid in which liquid metal nano and mineral nano colloids are mixed (S120); accommodating the liquid synthetic colloid and water in a predetermined ratio in a container (S130); It is a configuration including a step (S140) of stirring the mixed liquid synthetic colloid and water at a predetermined temperature for a predetermined time.

The plurality of liquid metal nanocolloids are liquid gold (Au) nanocolloids, liquid platinum (Pt) nanocolloids, liquid silver (Ag) nanocolloids, liquid palladium (Pd) nanocolloids, liquid iridium (Ir) nanocolloids, liquid It may include at least two or more of aluminum (Al) nano colloids, liquid iron (Fe) nano colloids, liquid copper (Cu) nano colloids, and liquid nickel (Ni) nano colloids.

The at least one liquid mineral nano colloid may include at least one of a liquid mosanite nano colloid, a liquid jade nano colloid, a liquid germanium nano colloid, a liquid elvan stone nano colloid, a liquid auricle nano colloid, and a liquid tourmaline nano colloid.

The colloid used in the embodiment of the present invention is called colloid, and the state in which particles larger than normal molecules or ions and having a diameter of about 1 nm to 1000 nm are dispersed in a gas or liquid is called a colloidal state, and the entire colloidal state is referred to as a colloidal state. called colloids. The colloidal particles dispersed are called dispersoids, and those surrounding them are called dispersion medium. A colloid is a hydrophilic colloid, in which the dispersoid has an affinity for water like starch and protein, and as a hydrophobic colloid, a dispersoid has no affinity for water like a metal powder. In the present invention, a hydrophobic colloid containing metal nanoparticles is used.

The metal nanoparticles used in the embodiment of the present invention have a property of aggregating with each other and are not stabilized by themselves. However, the metal nanoparticles contained in the metal nano colloidal solution are stabilized. The reason is, for example, platinum nanocolloids have a negative charge, and copper nanocolloids have a positive charge. The reason why the metal nanoparticles are not agglomerated and stabilized in the metal nanocolloidal solution is that the metal nanoparticles have the same electricity and are pushing each other.

In particular, a nanomaterial is a material in which one of the dimensions of the material, such as width, length, and diameter, is less than 100 nm. In the case of nanomaterials, due to their extremely small size, the ratio of surface elements to the same mass is dramatically increased compared to conventional microparticles. Due to this, it has excellent surface properties with excellent activity and is characterized in that the size of the surface area is maximized.

These platinum group nanoparticles have a characteristic of having high efficiency as a catalyst, and have particularly similar physical and chemical properties. As a catalyst material that is already widely used in industry, it is widely used as a catalyst for the reaction of oxidizing carbon monoxide (CO) and unburned hydrocarbons, especially in catalytic converters, which are automobile exhaust gas purification devices. However, platinum group nano itself is highly toxic, so it is mainly developed as a catalyst for platinum-nickel and platinum-copper alloys to improve stability and skin toxicity. In particular, platinum has antioxidant power to reduce oxidation by active oxygen, and liquid platinum nanocolloids have a property of further increasing antioxidant power by increasing specific surface area. In addition, platinum, which is an active metal, is known to reduce NO _x concentration by converting NO to NO ₂ and performing a NO _x decomposition reaction in which some NO _x is directly decomposed into N ₂ without a separate reducing agent.

Silver nanoparticles of liquid silver nano-colloids that can be used in an embodiment of the present invention are copper-group elements and have excellent mechanical properties such as gloss, ductility and electrical conductivity, and are used in various fields. In particular, the liquid silver nano-colloids exhibit excellent antibacterial properties even at low concentrations, and as the mixing ratio of the silver nano-colloids solution increases, excellent deodorization properties are exhibited, and the air permeability is increased after processing.

In addition, silver nanoparticles exhibit a unique optical property called localized surface plasmon resonance (LSPR) together with gold. This refers to a phenomenon in which electrons collectively vibrate due to the resonance of free electrons inside the metal with an external electromagnetic field, which causes the nanoparticles to strongly absorb and scatter light of a specific wavelength. In particular, silver nanoparticles have a narrower wavelength and stronger LSPR characteristics than gold nanoparticles.

Copper nanoparticles of liquid copper nano-colloids that can be used in an embodiment of the present invention are very useful in various industries due to their excellent electrical conductivity and relatively low price. Copper nano has no fear of ion migration, has excellent wettability and adhesion to materials, and has excellent insulation and heat dissipation effect.

The aluminum nano-colloid of liquid aluminum nano-colloid that can be used in an embodiment of the present invention exhibits optical resonance over a spectrum of a wider region than gold or silver. In addition, it is cheaper than gold or silver and has the characteristic that oxides do not penetrate.

Nickel nanoparticles of liquid nickel nano-colloids and iron nanoparticles of liquid iron nano-colloids, which can be used in an embodiment of the present invention, have their own magnetism and are used as important magnetic materials. In particular, nickel nano is mainly used for the internal electrode layer of the multilayer ceramic capacitor.

Elvan stone nanoparticles of liquid elvan stone nanocolloid that can be used in the embodiment of the present invention are known to adsorb heavy metals such as CN, Cd, Hg, residual chlorine, E. coli, and radioactive materials because of their strong adsorption power, and contained in elvan stone Due to the mineral components such as Mg, Fe, Mn, Al, Ge, Si, Ca, it is widely used for drinking water and water purification. It also has its own far-infrared radiation characteristics.

The jade nano particles of the liquid jade nano colloid that can be used in an embodiment of the present invention have the property of emitting their own far-infrared rays from the jade.

It is a natural mineral of the feldspar family called feldspar. There are two types of guiyangstone, red and white, and the white guiyangstone has the highest far-infrared emissivity of 96% among ore, and the red guiyangstone generates 24,000/cc of anions, which is 10 times higher than that of tourmaline.

Of course, the plurality of liquid metal nano-colloids and at least one liquid mineral nano-colloids that can be used in an embodiment of the present invention are not limited to the above types. A liquid colloid containing various metal nanoparticles and mineral nanoparticles exhibiting the functions of the above-described metal nanoparticles and the functions of the mineral nanoparticles may be used.

For example, in order to increase the combustion efficiency in the combustion device and to reduce the harmful components contained in the exhaust gas by the improved combustion efficiency, the quality of the fuel and the quality of the mixed air depend. The present invention optimizes air quality and injects it into the combustion chamber to increase combustion efficiency and reduce harmful components of exhaust gas, as well as improvement of the cylinder inner wall of the combustion chamber and NO _x , SO by the substances contained in the air mixed into the fuel _x It relates to a method for producing a liquid composition for filter media, which improves combustion efficiency and reduces harmful components contained in exhaust gas by reducing harmful components, and the composition thereof.

However, the present invention is not limited to liquid metal nano-colloids and liquid mineral nano-colloids. Embodiments of the present invention may be implemented with various solutions in which metal nanoparticles are dispersed and various solutions in which mineral nanoparticles are dispersed.

<Improvement of combustion efficiency of combustion device>

The higher the moisture content in the air mixed into the combustion chamber in the combustion device, the longer the ignition time of the ignition device in the combustion chamber, and consequently, the combustion efficiency is lowered and the torque of the device is lowered. Therefore, optimizing the moisture content in the air mixed into the combustion chamber increases the combustion efficiency of the combustion device.

In addition to harmful components contained in the air, fine dust and various types of heavy metal particles are present. Among these fine dust and heavy metal particles, most of them are filtered by the filter medium of the combustion device, but fine dust and heavy metal particles with a size of 0.1 μm to 0.5 μm are not filtered by general filter media (for air cleaner), so the air into the combustion chamber is not filtered. It causes damage to the cylinder of the combustion chamber and lowers the combustion efficiency of fuel.

Platinum group nanoparticles or alloy group alloy nanoparticles of platinum and palladium of liquid platinum nanocolloids and liquid palladium nanocolloids that can be used in an embodiment of the present invention are water electrolysis that decomposes water into hydrogen and oxygen It can function as a catalyst for Therefore, it is possible to improve the combustion efficiency of the combustion chamber by decomposing moisture in the air mixed into the combustion chamber of the combustion apparatus and mixing hydrogen and oxygen into the combustion chamber.

Silver nanoparticles that can be used in an embodiment of the present invention have a unique optical property called localized surface plasmon resonance (LSPR) together with gold, which is due to the resonance of free electrons inside the metal with an external electromagnetic field. As a phenomenon of vibration, it is known to have excellent antibacterial and deodorizing functions. In particular, since the antibacterial action of silver nanoparticles combines with oxygen molecules in the air and releases active oxygen with strong oxidative action, various bacteria and viruses in the air are attached to the silver nanoparticles to sterilize and deodorize them. Bacteria have a size of 1 μm to 5 μm, and viruses are known to be 200 to 300 nm smaller than bacteria. Therefore, these bacteria and viruses are not filtered in the general air cleaner media, but are incorporated into the air in the combustion chamber as they are, and can act to reduce the combustion efficiency together with fine dust and heavy metal particles. By sterilizing these bacteria and viruses by collecting and sterilizing these bacteria and viruses by the resonance of electromagnetic fields and free electrons by silver nanoparticles or gold nanoparticles, it is possible to improve combustion efficiency by preventing the mixing of bacteria and viruses, which are fine particles, in the combustion chamber as well as antibacterial and deodorization after combustion. there is.

Among internal combustion engines, for example, an engine system compresses air introduced into a combustion chamber at high temperature and high pressure, injects and atomizes fuel with a greater pressure, ignites it, and then discharges exhaust gas. Such an engine system includes an engine having a combustion chamber in which fuel is burned, and a turbocharger (including a compressor and a turbine) connected to the engine. Here, in order to increase fuel efficiency, the engine system pre-compresses air in the compressor and supplies it to the combustion chamber. In this way, a supercharger that compresses and injects air using exhaust gas pressure discharged from the engine is connected to the engine. Such an engine system is installed in a limited space, and a turbine and a compressor are provided adjacent to the engine. Accordingly, heat generated from the engine is transferred to the compressor, and the scavenging air (air entering the compressor; intake air) temperature may be increased. When the scavenging air temperature rises, not only does the fuel efficiency of the engine become inconsistent, but when the scavenging air temperature is high, the oxygen ratio is lowered (because the air density is low and the amount of air used in the combustion process is reduced), which causes the engine's efficiency to drop. .

As described above, the copper nanoparticles of the liquid copper nanocolloids used in the embodiment of the present invention have excellent thermal conductivity, and thus a heat dissipation function is performed on the adsorbed material. Accordingly, it is possible to function to reduce the temperature (the desired temperature) of the air entering the compressor, thereby preventing the density of the air entering the combustion chamber from being lowered, thereby increasing the combustion efficiency of the combustion chamber.

In addition, the nickel nanoparticles or iron nanoparticles used in the embodiment of the present invention are contained in the air due to their magnetic properties, and the heavy metal particles that are difficult to filter in the filter media are attached to it to increase the quality of the air mixed into the combustion chamber and improve combustion efficiency. can be improved

A plurality of metal nanoparticles and at least one mineral nanoparticles that are immersed in the liquid composition for filter media of the present invention and are stabilized on the surface and inside are distributed and adsorbed. Not only does it prevent the fine particles contained in the medium from passing through the filter medium, but the air resistance mixed into the filter material does not increase due to the nature of the nanoparticles, so it is possible to maintain the oxygen content in the air. And by decomposing the moisture contained in the air into hydrogen and oxygen to be mixed into the combustion chamber, it is possible to further improve the combustion efficiency.

2 is a graph image showing a comparison test result of combustion efficiency performance of a filter medium to which the liquid composition prepared by the method for preparing the liquid composition for a filter medium of the present invention is applied and a general filter medium.

In order to maintain the objectivity of the test results of the filter media to which the embodiment of the present invention is applied, the test results were derived by requesting the Department of Automobile Engineering of the Department of Transportation Mechanical Engineering of a domestic university rather than conducting a self-test.

In the test result report, the purpose of the test is to determine the performance of the nano air cleaner product, which was invented to improve the flow condition of intake air flowing into the engine. In order to evaluate this, the nano air cleaner product was tested by exchanging the dried air cleaner by applying the composition of Example in the dipping method with the same specifications as the general air cleaner at the time of testing.

As a test target, two tests were conducted on a domestically produced vehicle (Santa Fe 2.0 AT6 (2016 model) diesel vehicle with a driving record of 42,00 km).

As shown in FIG. 2 , the air cleaner for a combustion device in which the liquid composition for filter media of the present invention is applied to the same vehicle is compared to a case where a general air cleaner of the same specification is applied, based on the engine speed condition ( 1,700 rpm or less), fuel consumption was improved by 5 to 10%. In addition, based on the engine load condition, it was found that the fuel consumption was improved by about 20% under a high load condition of 60% or more. However, it was found that there was no difference within 1% under the low load condition.

<Reduction of harmful components in exhaust gas>

The harmful components contained in the exhaust gas after combustion of the combustion device are mainly NOx (NO _x ) generated by nitrogen contained in the air and SOx (SO _x ) generated during the combustion of fuel are contained in the exhaust gas and discharged, and are discharged to the atmosphere. It is known to combine with moisture and oxygen in it to produce smog, a so-called main culprit of environmental pollution. Therefore, reducing the Knox and Sox emitted from the combustion device is the key to solving the problem of environmental pollution.

The proportion of dry air, excluding water vapor, of the air constituting the atmosphere mixed into the combustion device is almost constant all over the earth. The component ratio of dry pure air is nitrogen N ₂ 78.03%, oxygen O ₂ 20.99%, argon Ar 0.93%, carbon dioxide CO ₂ 0.03%, and other 0.02% exist. In addition, the moisture content in the air appears to be about 17.3 g/m 3 at room temperature of 20°C. Among them, the treatment of moisture in the air has been described as a catalytic function of metal nanoparticles to increase the above-described combustion efficiency. Therefore, it can be seen that the reduction of Knox and Sox contained in the exhaust gas is the core content of the present invention. Among them, the reduction of the sox is a fuel problem of the combustion device, so here we will focus on the effect of the present invention for reducing the rust.

Nitrogen, which accounts for most of the air mixed into the combustion device, becomes harmful in the exhaust gas of the combustion device through the following process.

Nitrogen molecules in the air are very stable because nitrogen atoms are bonded to each other by triple bonds. However, it reacts with oxygen at high temperature and high pressure like in a car engine to produce nitrogen monoxide (NO) as shown below.

N ₂ (g) + O ₂ (g) → 2NO (g)

Nitrogen monoxide is highly reactive and reacts with oxygen to produce nitrogen dioxide (NO ₂ ) as shown below.

2NO(g) + O ₂ (g) → 2NO ₂ (g)

Nitrogen dioxide (NO ₂ ) meets with water to form nitric acid as shown below and becomes the main culprit for acid rain.

3NO ₂ (g) + H ₂ O(l) → 2HNO ₃ (aq) + NO(g)

Nitrogen oxide (NO _x ), so-called rust, causes photochemical smog.

In this way, nitrogen, which occupies most of the air, is mixed in the combustion device to generate nitrogen monoxide by high temperature and high pressure in the combustion chamber, and nitrogen monoxide is included in the exhaust gas and discharged into the atmosphere, thereby becoming nitrogen oxides, the main culprit of air pollution. A so-called denitration device or denitrification material for reducing this is being applied to a combustion device, and is being studied steadily.

As described above, the platinum group nanoparticles used in the embodiment of the present invention are oxidized at a high temperature to react with nitrogen (NO), nitrogen is reduced and NO ₂ is increased, and as a result, it appears to reduce rust (NO _x ).

In addition, it has been shown that the stabilized platinum group nanoparticles react with nitrogen. Since the platinum group nanoparticles used in the embodiment of the present invention are mixed in a small amount in the combustion chamber of the combustion device, they react with nitrogen contained in the air in a high temperature environment of the combustion chamber to convert to NO ₂ and reduce the rust emitted as exhaust gas do

In addition, the mineral nanoparticles used in the embodiment of the present invention emit far-infrared rays from themselves to purify the air mixed into the combustion chamber, thereby reducing the combustion efficiency of the combustion chamber as well as harmful components contained in the exhaust gas. .

For example, components included in exhaust gas emitted from an automobile engine system are represented by HC, CO, NO _x , soot, and F/E.

The results regarding the test results of FIG. 3 are presented in Table 1.

As the test values shown in Table 1, the test results of applying the air cleaner to which the embodiment of the present invention is applied to the engine system, compared to the same vehicle and the same air cleaner specification, among the harmful components in the exhaust gas, HC 30.3%, CO 83.4 It can be seen that %, NO _x 94.8%, soot 70.3%, and F/E 0.2% were removed.

In the test laboratory, the test results showed that rust was reduced by about 90%, soot by about 70%, HC by about 30% and CO by about 83% in exhaust gas of the test car.
