Description

Method for reducing smoke of diesel vehicle

The present invention relates to a method for reducing soot by using an additive which is added directly to a fuel, unlike the prior art by a mechanical configuration or a post-treatment device, and more specifically, treated with far-infrared radiation material containing various metal elements. The present invention relates to a method for reducing soot in diesel vehicles by using an organic solvent modified by purified water as an additive.

Diesel diesel has been applied to large vehicles such as trucks and buses because it has lower fuel economy and better output than gasoline vehicles. However, as diesel vehicles are applied to small vehicles, demand in advanced countries continues to increase. However, in developed countries, such large and small diesel vehicles account for 40% of the total air pollution, which is recognized as a major cause of air pollution, mainly caused by nitrogen oxides (NOx) and particulate matter (PM). . Nitrogen oxides and particulate matter have trade-offs with each other, so developed countries are adjusting their levels according to policy requirements. In order to reduce the emission of air pollutants, advanced countries are tightening emission regulations of diesel engines. Therefore, soot acceptance criteria are becoming increasingly strict. As a countermeasure to satisfy the diesel emission regulations of diesel engines, there are a method of improving a diesel engine and developing a post-treatment technique and mounting them on the exhaust gas.

Such post-treatment techniques include, for example, (1) an oxidation catalyst for purifying unburned hydrocarbons in particulate matter (2) and a particulate particulate filter for filtering particulate matter (PM) through a filter. (Hereinafter referred to as 'DPF') (3) DeNOx catalyst system for decomposing or reducing nitrogen oxides (NOx) under reducing atmosphere.

In addition to the above techniques, many mechanical soot reduction apparatuses are known. For example, Korean Patent Publication No. 2004-0068792, 2004-0046579, and the like.

Hereinafter, the present invention will be described in more detail.

The present invention is a diesel vehicle soot smoke reduction method,

First, the raw material of the far-infrared radiation material is dried at room temperature for 10 hours, and then fired at 600-800 ° C. for 8 hours to produce the far-infrared radiation material, and then put into a mill to be pulverized into fine particles.

The raw material of the far-infrared radiation material is 80 to 85% by weight of silicic anhydride (SiO2), 6 to 8% by weight of aluminum oxide (Al2O3), 0.5 to 1% by weight of ferric oxide (FeO), 0.5 to 1% by weight of ferric oxide (Fe2O3) %, Magnesium oxide (MgO) 1-3 wt%, calcium oxide (CaO) 1-3 wt%, sodium oxide (Na2O) 1-3 wt%, potassium oxide (K2O) 1-3 wt%, titanium dioxide (TiO2 ) 0.1 to 0.2% by weight, phosphoric anhydride (P 2 O 5) 0.1 to 0.2% by weight, and manganese oxide (MnO) 0.01 to 0.03% by weight.

The conventional far-infrared radiator has a high content of the alumina component, but the main range was limited due to the high price, but the far-infrared radiator of the present invention has a relatively low content of the alumina component and the silicic anhydride as the main component do.

In addition, the far-infrared radiating material of the present invention includes a variety of metal oxides, can be purchased at low cost and suitable for mass production. It also emits far-infrared radiation in the range of about 5 to 20 μm and also has an organic gas barrier effect, such as ammonia.

Next, the far-infrared radiation substance pulverized in the particulate state is put into a sealed container filled with purified water and aged for 24 hours while irradiating ultraviolet rays.

Then, the fermented material is mixed with 5 ~ 20 parts by weight based on 100 parts by weight of the pulverized fine particles in the aged purified water, and then maintained at a temperature of 70 ~ 80 ℃ fermentation for 24 hours.

In this step, the fermentation material is 0.6 parts by weight of protein, 0.5 parts by weight of lipid, 0.04 parts by weight of carbohydrate, 2 parts by weight of calcium, 10 parts by weight of phosphorus, 0.1 parts by weight of iron, 6 parts by weight of sodium, 6 parts by weight of potassium, 7 parts by weight of retinol, and 0.9 parts by weight of beta-carotene.

The protein in the fermentation material is not particularly limited and may be animal or vegetable.

In the case of the lipid, as well as known phospholipids, one can be easily obtained such as lecithin.

The carbohydrate may be used as it is grain or refined carbohydrate powder.

The calcium, phosphorus and iron may be present in the form of an acid or salt, for example, calcium chloride, calcium carbonate, phosphoric acid, sodium salt of phosphoric acid, iron chloride, ferrous oxide, ferric oxide and the like may be used.

The sodium and the knife may also be used in the form of sodium chloride and potassium chloride.

In the case of retinol, an industrial grade may be used as it is, and in the case of beta-carotene, an industrial grade may be used.

Subsequently, the purified water passed through the fermentation step is filtered and then aged for 6 hours.

Subsequently, a mixed solution prepared by mixing 600 parts by weight of the organic solvent with 100 parts by weight of the filtered and aged purified water was prepared, and then the mixed solution was stirred at 850 rpm for 3 hours. By such stirring, the organic solvent and the purified water are dispersed and mixed with each other.

Next, the organic solvent layer is recovered through phase separation in the stirred mixture.

In the recovered organic solvent layer, a trace amount of metal elements in which the purified water layer is dispersed in the stirring is transferred to the organic layer to include the metal elements. The phase separation is separated by a conventional separation device. The organic solvent layer thus separated becomes an additive capable of reducing soot.

Finally, when the recovered organic solvent layer is added at a ratio of 0.5 parts by weight with respect to 100 parts by weight of fuel, soot is reduced when the diesel vehicle is driven. For example, the soot may be reduced by adding the soot reducing agent in a predetermined ratio to the fuel oil of the diesel car.

More preferably, it is added in the ratio of 0.1-0.5 weight part. When the amount is less than 0.1 part by weight, the smoke reduction effect is low. When the amount is more than 0.5 part by weight, the difference in the smoke reduction effect is not large.

In the method for reducing soot, many metal elements included in the far-infrared radiating material are included in purified water through a purification process through filtration and aging, and are dispersed in an organic solvent through mixing with an organic solvent. When the organic solvent in which the metal elements are dispersed in ionic form or the like is added to diesel, the metal elements act as a catalyst during combustion to reduce the smoke by promoting complete combustion.

In particular, these metal elements may be metal elements having catalytic activity contained as impurities in the components constituting the far-infrared radiating material.

In the diesel vehicle soot reduction method, the space that is confined for 10 hours while maintaining the water content of 10% by weight or less of the far-infrared radioactive material pulverized in the particulate state before the fine-infrared radioactive material pulverized into the purified water. After storing in the extrusion step into the extruder into a solid of a predetermined form; And

It is preferred to further include; further comprising the step of high-temperature baking the solid extrusion molded in a predetermined form for 10 hours at 1200 ~ 1300 ℃.

By this additional firing is to produce a far-infrared emitting material having improved physical properties.

In the diesel fuel vehicle soot reduction method, it is preferable that the mixed liquid of the purified water and the organic solvent further includes 0.7 to 0.0007 parts by weight of the combustion catalyst with respect to 700 parts by weight of the mixed liquid.

The content range of the combustion catalyst is very low and corresponds to the ppm range. Remarkable effects can be obtained by the addition of such trace combustion catalyst.

The additional inclusion of this combustion catalyst makes it possible to adjust the combustion of diesel fuel closer to more complete combustion.

The combustion efficiency can be remarkably improved by such trace combustion concentration.

If the combustion catalyst content is out of the range, the catalytic effect is not large.

The combustion catalyst is preferably a compound comprising at least one metal selected from the group consisting of gold, silver, platinum, copper, mercury, aluminum, palladium, rhodium, iridium and asium.

More specifically, the combustion catalyst is ruthenium oxide (IV), ruthenium chloride (III), ruthenium chloride (III) trihydrate, rhodium oxide (III), iridium chloride (III), iridium oxide (III), osmium chloride (III) , Platinum black, platinum oxide (IV), platinum chloride (II), platinum chloride (IV), dinitrodiamine platinum (II), palladium chloride (II), palladium oxide (II), palladium nitrate (II) hydrate, nitric acid Tetraamine palladium (II), rhenium chloride (III), cis-dichloro (2,2'-bipyridine) platinum (II), dichloro (1,5-cyclooctadiene) platinum (II), etc. are preferable.

In the step of adding the fermentation material to the purified water in the diesel vehicle soot reduction method, it is preferable to add a powdered protein to the fermentation material.

The powdered protein used herein is not particularly limited and may be animal or vegetable.

According to another embodiment of the present invention, the diesel vehicle soot reduction agent is dried for 10 hours at room temperature for the raw material of the far-infrared radiating material, and then fired for 8 hours at 600 ~ 800 ℃ to produce a far-infrared radiating material, then a crusher Pulverizing to a particulate state by putting in; Injecting the far-infrared radiation material pulverized into the particulate state into a sealed container filled with purified water and aging for 24 hours while irradiating ultraviolet rays; Mixing 5 to 20 parts by weight of the fermented material to 100 parts by weight of the pulverized fine particles in the aged purified water, followed by fermentation for 24 hours while maintaining the temperature of 70 ~ 80 ℃; Filtering the purified water after the fermentation step and aging for 6 hours; Preparing a mixed solution mixed with 100 parts by weight of the filtered and matured purified water in an amount of 600 parts by weight of an organic solvent, and then stirring the mixed solution at 850 rpm for 3 hours; And recovering the organic solvent layer through phase separation from the stirred mixed solution. The soot reducer can significantly reduce the content of NOx and / or SOx generated in light oil and / or heavy oil.
