This application is based upon and claims priority to Chinese Patent Application No. 202211190425.4, filed on Sep. 28, 2022, the entire contents of which are incorporated herein by reference.
The present invention relates to the technical field of fuel enhancing device, particularly nanomaterial ceramic spheres, a preparation method, and an application thereof.
In recent years, global warming and severe climate change have been mainly caused by the extensive use of petroleum products in which factories and diesel and gasoline vehicles are the primary sources of emissions.
However, due to the engine art being limited, the state of the prior art does not provide any solution for the complete combustion of the hydrocarbons in the fuel in the combustion chamber. Incomplete combustion of the hydrocarbons in the fuel leads to the loss of fuel, generation of a large amount of toxic exhaust gas, and results in severe air pollution and accumulation of carbon in combustion devices, which decreases the service life of the machines.
At present, for a variety of fuel-saving devices sold on the market, which are used in fuel tubes, fuel tanks, or battery wires, most of the devices adopt rubber material mixed with functional powder for thermoforming. However, consumers have not been very satisfied with fuel-saving devices thermoformed with a mixture of rubber material and functional powder, and the service life of the material is not long. Thus, there is much room for improvement in the proportion of material composition, dispersion, contact area, and preparation process.
The purpose of the present invention is to provide nanomaterial ceramic spheres, a preparation method, and an application thereof to solve the problem of the unsatisfactory use effect of a fuel-saving product in the prior art.
To achieve the purpose of the present invention, the present invention provides the following technical solutions:
The present invention provides nanomaterial ceramic spheres prepared from the following raw materials in parts by weight:
1-30 parts of nano-titanium dioxide, 1-30 parts of nano-zirconia, 1-30 parts of nano-tourmaline, and 1-30 parts of kaolin.
Preferably, the particle size of nano-titanium dioxide, nano-zirconia, and nano-tourmaline is 1000-10000 mesh independently.
The present invention also provides a preparation method for the nanomaterial ceramic spheres, including the following steps:
Steps (1) and (2) are not required to be in sequence.
Preferably, in step (1), the mass ratio of the first part of kaolin and water is 5-10: 1-3.
Preferably, in step (1), the particle size of the soft spheres is 0.8 mm-2.2 mm.
Preferably, in step (1), a baking temperature is 1100° C.-1400° C.; a baking time is 40 h-52 h.
Preferably, the mass ratio of the first part of kaolin and the second part of kaolin is (8-10):(6-8).
Preferably, in step (3), the mass ratio of the sphere cores, water, and the adhesive is (6-9):(0.1-2):(0.1-2); the particle size of the nanomaterial is 2 mm-30 mm.
Preferably, in step (4), the baking temperature is 800° C.-1300° C.; the baking time is 40 h-52 h.
The present invention further provides an application of the nanomaterial ceramic spheres in enhancement, activation, promotion of efficient fuel combustion, and reduction of exhaust emissions.
The technical principle and advantages of the present invention are as follows:
One of the main reasons that fuel can not be fully and completely burned in a cylinder is that the composition of the fuel contains hydrocarbon molecules with high molecular weight, such as benzene, etc. It takes time for these large hydrocarbon molecules to decompose and be burned adequately at high temperatures. A hydrocarbon group hidden in the innermost part of the molecules is often quickly discharged from the cylinder without the opportunity to be mixed and burned with oxygen in a short explosive period, so it becomes the main component of harmful exhaust gas.
Calculated by the theoretical model of an electron gas in quantum mechanics, the fundamental modes of such molecules are estimated to be about 0.09 eV-0.42 eV. Further, derived from Planck's formula, the following simplified formula of photon kinetic energy is obtained:
λ(μm)=1.2398(eV−μm)/E(eV),
where λ, is the wavelength of the photon with the unit of micron (μm) and E is the kinetic energy of the photon with the unit of electron volt (eV).
It can be calculated by using the formula: Far-infrared photons with wavelengths between 3 μm-14 μm can provide enough energy to overcome potential energies of 0.09 eV-0.42 eV, so the electrons trapped in the force field are excited by resonance to increase the fundamental modes. In fact, in the study of organic chemistry, it has been pointed out that: Infrared rays with wavelengths of 3 μm-14 μm can trigger molecular stretching and bending vibrations. On the other hand, according to the infrared absorption spectrum of organic chemistry, saturated covalent bonds (C—H) in hydrocarbon molecules can absorb photons at 3.2 μm-3.6 μm wavelength in resonance, while the non-saturated divalent carbon bond (C═C) and trivalent carbon bond (C≡C) can absorb photons in the bands of 5.8 μm-6.2 μm and 4 μm-4.7 μm, respectively.
Based on the above reasons, the family of hydrocarbon molecules has an infrared-active property to absorb far-infrared photons at a range of 3 μm-14 μm to produce stretching and bending resonance vibrations of molecular bonds, thereby reducing a chemical reaction activation barrier and increasing a chemical reaction rate. It can be seen that far-infrared rays can excite bond energies between molecules of fuel by resonance. Only a small amount of energy can break the Van der Waals force between the molecules of fuel, so clusters of the molecules of fuel become smaller and have higher kinetic energy, which is easy to fully fuse and burn with oxygen and recombine to form carbon dioxide and water vapor along with releasing energy. In short, the heat energy conversion efficiency of fuel (liquid and gas) in the cylinder of the engine can be improved. Thus, the same output power can be achieved with less fuel consumption. At the same time, the concentration of emitted hydrocarbon and carbon monoxide caused by incomplete combustion or the concentration of emitted micro-carbon particles in diesel engines will also be significantly reduced. In addition, because the heat energy contained in the fuel is transferred into effective work and the heat consumption of the exhaust gas is relatively reduced, the temperature of the exhaust gas will not be increased, thereby suppressing the generation of NOx. Generally, not only the energy conservation can be achieved, but exhaust emissions can also be generally reduced.
The inventor of the present application uses several nano-scale natural ores to invent nano ceramic granulation technology. The technology uses kaolin as a combined component of several nanomaterials and adopts the process of rubbing and sticking to produce a porous surface and stacking layers, which were crystallized into spheres after sintering at the condition of high temperature of 1300° C. The spheres provide the best wavelength irradiance for fuel enhancing device and increase the contact surface area to maximize the characteristics of nanomaterial, which has the advantages of weather resistance, non-combustibility, acid-alkali resistance, antistatic, etc.
The electrons of the far-infrared radiation ceramic materials prepared by the present disclosure can be excited to a higher energy level by absorbing the ambient heat energy above absolute zero (or minus 273 degrees Celsius). The wavelength of photons released can fall into the far-infrared spectral range with microns wavelength, which is the most suitable for fuel enhancing device, thereby significantly improving the efficiency of fuel combustion and meeting the functional requirements of energy conservation.
In addition, the nano far-infrared ceramic spheres are only a medium for energy transfer without any chemical reaction involved. Further, due to the eternal existence of environmental thermal energy, the nano far-infrared radiation of the fuel enhancing ceramic spheres will not be exhausted and can be permanently effective.
The present invention provides nanomaterial ceramic spheres prepared from the following raw materials in parts by weight:
1-30 parts of nano-titanium dioxide, 1-30 parts of nano-zirconia, 1-30 parts of nano-tourmaline, and 1-30 parts of kaolin.

This wavelength falls in the range of the infrared spectrum with the wavelength of 3 μm-14 μm, which is most suitable for fuel enhancing device. Through the Van der Waals force between fuel molecules, the fuel molecules become smaller and have higher kinetic energy, so it is easier to fully fuse with oxygen and burn, thereby significantly improving the combustion efficiency of fuel and achieving the functional requirements of energy conservation.
