Description

  The present invention relates to an α-ray emitter that performs processing such as sterilization, deodorization, low molecular weight, activation, and deterioration prevention mainly of fluids such as water, air, and fuel oil using the ionizing action of α-rays. Relates to the device.

  Conventionally, in order to promote combustion of an internal combustion engine and other combustion devices that improve combustion efficiency by irradiating air or fuel, fuel and air or air-fuel mixture with alpha rays having an ionizing action, as shown in Patent Document 1, A granular material with thorium oxide, which is an α-ray emitting material, attached to the surface is held by a holding material such as a wire mesh at predetermined intervals, and this holding material is installed in the direction of the air flow direction in the air cleaner of an automobile engine. Is known.

Thorium oxide is generally known as an α-ray emitter, and it is widely known that α-rays have the weakest ionization effect, although they have the weakest ability to penetrate substances (penetration power) compared to other types of radiation. Yes.
Japanese Patent Laid-Open No. 2005-9898

  However, as shown in the above-mentioned Patent Document 1, in order to hold a material containing an α-ray emitting material made of thorium oxide attached to the surface of the granular material and fired, the wire mesh or the like is granulated. In addition, there is a disadvantage that the radiation material on the surface is damaged by holding on the wire mesh.

  Furthermore, when using a granular ceramic processing material as described above, in order to hold the granular radiation material, it is necessary to sandwich two granular metal nets and sandwich the granular material, and the particle size of the granular material Is about 5 mm, and there are many soldered portions fixed to the metal mesh, and the space ratio of the processing cylinder is reduced.

  The present invention provides an α-ray radiator for fluid processing and an apparatus using the radiator for solving the above-mentioned problems. In particular, the large ionization effect (ionization) of α rays changes the molecular structure of water, air, oil, etc., and in the case of water, sterilization, deodorization, decolorization, etc. of water is performed efficiently by strong ionization. is there.

In addition, strong ionization generates artificial conversion of air molecule nuclei to improve combustion efficiency, deodorization, and sterilization of airborne bacteria.
Furthermore, oils are intended to be activated by strong ionization and to prevent deterioration. Of these, fuel oil improves combustion efficiency by making small molecules and radicals by breaking carbon molecular bonds.

  In order to solve the above problems, the present invention firstly provides a heat-resistant material on the surface of the holding core material 6 formed in a net-like or lattice-like shape with predetermined meshes or intervals allowing fluid to flow with a material having heat resistance. A fixing layer 8 is formed by applying or adhering a fixing material made of a conductive paint or an adhesive, and a fine granular or powdery α-ray emitting material 7 containing thorium oxide as a main material is formed on the fixing layer 8. The α-ray emitting material 7 and the fixing layer 8 are fixed to the holding core material 6 by firing at a predetermined temperature.

  Second, the holding core member 6 is characterized by comprising a metal mesh made of copper, stainless steel, or other metal.

  3rdly, it is characterized by the interval of the wire of a mesh | network or a grating | lattice having been 5-30 mm.

  Fourth, the fixing material is characterized by comprising a polymer mainly composed of silicon, titanium, and carbon, an inorganic compound, and an organic solvent.

  Fifth, the α-ray radiator 4 is disposed in a cylindrical processing cylinder 1 having an internal space as a fluid flow path so as to intersect the fluid flow direction and partition the upstream side and the downstream side in the processing cylinder 1. It is characterized by being installed.

  The α-ray radiator and the device of the present invention configured as described above have a fine powder or powdery α-ray emitting material on a substantially front surface through a fixing layer on the surface of a mesh-like or lattice-like holding core material. Since they are attached, there is an advantage that α rays can be emitted from the entire holding core material, the α ray radiation density is high, and the amount of α ray radiation to the fluid passing through the holding core material is large. As a result, the processing performance by α-ray radiation is improved as compared with conventional radiators and radiation devices.

  Furthermore, since the α-ray emitting material adheres to the surface of the fixing layer and is fixed by firing, it is efficiently radiated to the surface side in contact with the fluid without hindering α-ray emission, and the fixing is stable and other fixings are also possible. There is no dropout or damage because there is no contact.

  Since the holding core material is simply a combination of wires in a mesh or lattice shape, there is no flow resistance to the fluid, and there is a large amount of α-ray radiation as described above, so there is no need to install multiple layers. . Even if a plurality of stages are installed, there is an advantage that fluid processing can be performed with higher performance with a smaller number (stage number) than the conventional one.

  Since the radiant material is only attached to the surface of the wire mesh and fired, there is no need for granulation, surface coating, or mechanical processing for fixing to the wire mesh as in the past, and the manufacturing cost can be reduced, and the material is sandwiched by the wire mesh. Since there is no surface contact with other members as in the case of doing, there is no inconvenience such as damage or deterioration of the surface of the radiation material.

  The embodiment of the present invention shown in the drawings will be described below. FIGS. 1 to 3 show the entire section of the usage state of the apparatus of the present invention and the state in which the main part of the radiator is sequentially enlarged and displayed.

  The apparatus shown in FIG. 1 shows an example of an intake air processing apparatus attached to the intake side of an automobile engine or the like. A cylindrical processing cylinder 1 is provided with an intake port 2 and an exhaust port 3. Inside, two mesh-like α-ray radiators 4 capable of passing air through a predetermined interval are installed so as to intersect the air flow direction and partition the air upstream side and the downstream side. Even if one radiator 4 is used in order to reduce the internal air flow resistance, a sufficient processing function can be exhibited.

  As shown in FIG. 2, the radiator 4 includes a core material 6 for holding a radiation material made of a wire net made of copper or stainless steel having a wire diameter of about 0.5 mm and a wire mesh of about 5 mm. As shown in FIG. 3, an α-ray emitting material 7 containing at least 0.2 to 5 wt% thorium oxide is attached to the entire surface of the core material 6 as shown in FIG. .

  The radiant material 7 is a base material formed by previously coating the surface of the core material 6 with a heat-resistant paint or adhesive as a fixing material of the radiant material 7 by dipping, spraying, brushing, or the like. The adhesive layer 8 is adhered and fixed. This final fixing is performed by heating and baking at 500 to 600 ° C. after fixing the radiation material 7. At this time, it is necessary to prevent the surface of the radiation member 7 from being covered with a paint or the like so that the α-ray emission is not hindered.

  As described above, the object to be treated by α-ray radiation covers not only combustion air but also fluid fuels such as water, oil, petroleum, gas, etc. and other α-ray irradiation treatments or effective fluids in general.

  The mesh of the metal mesh of the core 6 and the wire diameter are selected according to the size of the processing apparatus used and the air volume, etc., but the mesh considers the range (about 25 mm) of α rays, workability, fluid flow resistance, etc. Then, about 5-30 mm is desirable. Further, if α rays are radiated to the entire cross section of the flow passage, it is not always necessary to have a mesh, and it may be a lattice or may be processed by a punch. The material is not limited to metal as long as it has heat resistance enough to withstand firing.

  The material of the fixing material (adhesion layer 8) is excellent in high temperature resistance, chemical resistance and oxidation resistance composed of a polymer mainly composed of carbon, an organic compound and an organic solvent. For forming a thin film, it is possible to use a commercially available product with a trade name such as “Tyranno Coat”, or a paint for thin film that can be made into a ceramic. Further, the particle diameter of the α-ray radiation material 7 varies depending on the use conditions of the apparatus, but a particle having a size of about 40 to 500 μm (40 to 400 mesh) can be used.

  Next, the exhaust gas composition in the case where the apparatus of the present invention shown in FIG. 1 and below (however, only one α-ray radiator 4) is attached to the engine intake side of an automobile and the intake air is subjected to α-ray emission treatment and when it is not installed is shown. It shows about the change of. By the way, the car used for the test was in a state where it could not be used (running) because the HC and CO values exceeded (see Table 1) according to the state law.

  According to the results of Table 1, when the apparatus of the present invention is installed, the HC, CO, NOx content in the exhaust gas not only clears the California regulation values, but greatly It is clear that there is an improvement. Further, the measurement result is remarkably improved in comparison with the improvement results of HC, CO, and NOx in Patent Document 1.
