Description

  The present invention relates to a combustion improving plate for improving the combustion efficiency of a combustion apparatus and a combustion improving apparatus using the same.

  “Combustion” is a phenomenon in which heat or light is generated by the combination of air (more precisely, oxygen in the air) and fuel. The combustion device uses the phenomenon to obtain power and heat, and typical examples thereof include engines such as automobiles, generators, boilers, blast furnaces, kiln furnaces, and the like.

  The combustion efficiency of the combustion device is said to be about 60% for a gasoline engine and about 80% for a diesel engine, for example, and the remaining 20 to 60% of the fuel is released into the atmosphere without contributing to combustion. It is the actual situation. For this reason, efforts to improve combustion efficiency have been continually made from the viewpoint of reducing fuel costs and avoiding air pollution.

  There are three approaches for improving combustion efficiency: those related to fuel, those related to the structure of the combustion chamber, and those related to intake air. The present invention corresponds to the third “related to intake air”.

  As conventional techniques for improving combustion efficiency related to intake air, for example, those described in Patent Documents 1 and 2 below are known.

  The technique described in Patent Document 1 (hereinafter referred to as the first conventional technique) is to improve the combustion efficiency by using magnetism. Specifically, one side of a strip-shaped metal thin plate (air supply) On the winding surface of the road, rod-shaped magnets are arranged at a plurality of positions so that the north and south poles face the surface at right angles to the longitudinal direction and at approximately equal intervals in the longitudinal direction. When the improvement material such as ceramic, tourmaline, quartz, zeolite, etc. is used alone or in combination on the metal sheet surface on the side, it is wound around the outer periphery of the air supply path, and the opposite sides of the even numbered bar magnets are mutually opposite. It arranges so that it may be located.

  Moreover, the technique (henceforth the 2nd prior art) described in patent document 2 is improving a combustion efficiency using a radiation, Specifically, the radioactive substance was stuck or apply | coated. The sheet material is arranged on the air supply path of the combustion apparatus.

JP 2002-242769 A JP 2004-346898 A

  The first prior art has a structure in which a plurality of rod-shaped magnets are attached to one side of a strip-shaped metal thin plate at right angles to the longitudinal direction, so that air supply paths with different sizes curved in a narrow space are provided. If configured, it may interfere with the installation, and in the state wound around the air supply path with different diameters, a plurality of bar magnets will not face each other, causing variations in drawing out the efficiency of combustion efficiency, There is a problem of lack of stability.

  In addition, since the second prior art uses a radioactive substance that emits radiation, there is a problem that it cannot be completely said that there is no influence on the human body even if the emission is extremely small. .

  The present invention has been made in view of such circumstances, and can be mounted anywhere in the air supply path of the combustion apparatus. In addition, it has good stability and has no health effect on the human body. An object of the present invention is to provide a safe combustion improving plate and a combustion improving apparatus using the same.

In order to solve the above object, a combustion improving plate according to claim 1 is a combustion improving plate used by being mounted on an air supply path of a combustion apparatus, and a coating layer is formed on one side of a metal plate. In addition, it is characterized in that a ground lead wire is connected to the metal plate.
The combustion improving plate according to claim 2 is characterized in that the coating layer contains a powdery piezoelectric element as a main component.
A combustion improvement apparatus according to a third aspect is characterized in that a plurality of the combustion improvement plates according to the first or second aspect are laminated.
According to a fourth aspect of the present invention, there is provided the combustion improving apparatus according to the third aspect, wherein the combustion improving apparatus according to the third aspect has a sandwich structure in which a laminate of a plurality of combustion improving plates is sandwiched between aluminum mesh nets. And
According to a fifth aspect of the present invention, there is provided the combustion improving apparatus according to claim 5, wherein the combustion improving apparatus is detachably attached to the outer peripheral surface of the air supply path for taking in air into the combustion chamber. It has a two-layer structure consisting of a thin metal plate having flexibility and a coating material applied to the surface of the metal plate, and the surface to which the coating material is applied closely follows the curved surface on the outer periphery of the air supply path. The metal plate is wound and held so as to come into contact with the metal plate.
The combustion improvement apparatus according to claim 6 is the combustion improvement apparatus according to claim 5, wherein the metal plate is made of aluminum or copper, and the coating material is a silicon-based material containing barium titanate. It is a mixed paint of a paint and a highly dielectric substance.

The combustion improving plate of the present invention can be deformed due to the configuration in which a coating layer is formed on one side of a metal plate. Therefore, for example, even the outer peripheral surface of the curved air supply path can be mounted following the surface shape.
Moreover, it is not necessary to pay attention to the combination of different polarities as in the case of using a magnet, and it can be used universally for various sizes of air supply paths, and there is no variation in the effect of improving the combustion efficiency.
In addition, since no harmful substances (radioactive substances etc.) are used, it is safe.
In addition, if a stack of multiple combustion improvement plates is sandwiched between aluminum mesh nets, the aluminum mesh nets will act as cushioning materials, and the combustion improvement plates may be accidentally dropped due to the vibration of the combustion device. Can be prevented.

<First embodiment>
FIG. 1 is a structural diagram of a combustion improving plate according to the first embodiment.
In this figure, a combustion improving plate 1 has a coating layer 3 formed on one side of a metal plate 2, one end of a conducting wire 4 is connected to the metal plate 2, and the other end of the conducting wire 4 is grounded (application target). Connected to the ground potential of the combustion apparatus). The metal plate 2 is made of a highly conductive material (for example, copper, gold, or an alloy containing them), and its plate thickness is as thin as possible (for example, about 0.2 mm) in consideration of deformability such as bending. To do. The length L of the metal plate 2 is determined in consideration of the outer peripheral length of the air supply path of the combustion apparatus to which the combustion improving plate 1 is applied. That is, it is set to a length L that is sufficient to wind around the outer periphery of the air supply path. The width W of the metal plate 2 determines the formation area of the coating layer 3 formed on one side of the metal plate 2 together with the length L of the metal plate 2, and the formation area of the coating layer 3 is Since there is a close relationship with the effect of improving combustion, the optimum formation area (the length L is determined from the outer circumference of the air supply path) in consideration of the desired improvement effect of combustion, the formation area of the coating layer 3 is exclusively width Depending on W.) may be set.

  The coating layer 3 is composed of a main component and subcomponents, and the main component is a powdery piezoelectric element 5 composed of fine (for example, about 3 microns) particles. The subcomponent 6 includes a holding agent for holding the piezoelectric element 5 uniformly, a conductive agent having a semiconductor property for smoothly moving charges generated in the piezoelectric element 5, and the piezoelectric element 5 and the holding agent. And an adhesive (or adhesive) for adhering the conductive agent to the surface of the metal plate 2.

  For example, lead zirconate titanate can be used for the piezoelectric element 5 in powder form. Further, for example, a heat-resistant paint can be used as the retaining agent of the subcomponent 6, a bamboo charcoal powder can be used as the conductive agent, and a silicone sealant can be used as the adhesive, for example. be able to.

Next, a usage example of the combustion improving plate 1 according to the first embodiment will be described.
FIG. 2 is a view showing an example of use of the combustion improving plate 1. In this figure, air 7 is supplied to a combustion chamber of a combustion apparatus (not shown) through a resin pipe-like pipe line (hereinafter referred to as air supply path 8). In addition, in this figure, although the air supply path 8 is made into linear form, this is the convenience of illustration. It may be curved.

  The combustion improving plate 1 having the above-described configuration is wound around the outer periphery of the air supply path 8, and this mounting is performed in such a manner that the longitudinal direction of the metal plate 2 of the combustion improving plate 1 extends along the outer periphery of the air supply path 8. Perform along the surface. At that time, it is a matter of course that the combustion improving plate 1 does not fall off from the air supply path 8. For example, the metal plate 2 may be attached to the air supply path 8 using a double-sided tape or an adhesive. Alternatively, both ends of the metal plate 2 wound around the outer peripheral surface of the air supply path 8 may be fixed with screws or the like. Alternatively, the belt may be pressed from above the metal plate 2 wound around the outer peripheral surface of the air supply path 8. In any case, it is only necessary that the wound metal plate 2 is firmly fixed so as not to drop off or shift due to vibration or the like.

  The main surface of the metal plate 2 wound around the outer peripheral surface of the air supply path 8 (formation surface of the coating layer 3) may be on the outer peripheral surface side of the air supply path 8, or the opposite surface. May be.

  Now, the combustion improving plate 1 of this embodiment wound around the outer peripheral surface of the air supply path 8 in this way is considered to contribute to the improvement of the combustion efficiency by the following principle. First, a case where the combustion improving plate 1 of the present embodiment is not used will be described. In this case, the flow of air inside the air supply path 8 is fast at the central part of the supply path and is slow at the inner wall part of the supply path. A curve 9 in the figure schematically represents the flow. The cause of the slow air flow at the inner wall of the supply channel is that the air supply channel 8 is made of a resin material, and static electricity is generated at the inner wall of the supply channel due to the air flow. This is because the flow is inhibited. The combustion improving plate 1 of the present embodiment is for removing this static electricity. In short, it eliminates the obstruction factor of the air flow and smoothes the air intake, thereby improving the combustion efficiency. It is. In addition, smooth air intake facilitates the transition of oxygen molecules contained in the intake air to a radical state (activated state; that is, a state that is easy to burn), thereby improving combustion efficiency. It is something to try.

  As described above, the combustion improving plate 1 of the present embodiment can remove static electricity generated on the inner wall of the air supply path 8, and this is based on the following mechanism. That is, the air supply path 8 around which the combustion improving plate 1 of this embodiment is wound is connected to a combustion apparatus (not shown), and vibrations associated with the operation of the combustion apparatus are transmitted to the air supply path 8. As described above, since the coating layer 3 including the powdered piezoelectric element 5 is formed on the metal plate 2 of the combustion improving plate 1, the coating layer 3 is made of the piezoelectric element 5 by the vibration described above. An electromotive voltage is generated. As a result of the electric field generated by the electromotive voltage acting on the inner wall surface of the air supply path 8, static electricity generated on the inner wall surface can be canceled out by the electromotive voltage and removed. In the drawing, the static electricity generated on the inner wall surface is represented as a positive charge (a plus sign with a circle), and the electromotive voltage for canceling it is schematically represented with a negative charge (a minus sign with a circle). Is for convenience of explanation.

  Now, in the combustion improving plate 1 of the present embodiment, the metal plate 2 constituting the plate is dropped to the ground (connected to the ground potential of the combustion device via the conducting wire 4). It is an indispensable matter for obtaining the mechanism, and the reason for grounding is to increase the air velocity without increasing the amount of combustion air.

  Since it comprised as mentioned above, the plate 1 for combustion improvement of this embodiment can acquire the following special effects.

(1) Since the combustion improving plate 1 of the present embodiment is composed of a thin metal plate 2 and a coating layer 3 including a powdered piezoelectric element 5 formed on the metal plate 2, combustion is performed. The improvement plate 1 can be freely bent as required. For example, even if the air supply path 8 to be wound is curved, the outer peripheral surface of the air supply path 8 is not hindered. Can be installed along. Therefore, the special effect that the mounting location of the combustion improving plate 1 is not limited is obtained.

(2) Furthermore, the combustion improving plate 1 of the present embodiment can be mounted on air supply passages of various outer peripheral lengths for general purposes, and also has the effect that the required combustion efficiency improvement effect can be exhibited as expected. That is, in the first prior art described above, it is necessary to make the opposite poles of the magnets face each other, and for this purpose, the arrangement interval of the bar-shaped magnets must be appropriately set according to the outer peripheral length of the air supply path. The arrangement interval of the bar-shaped magnets set appropriately is naturally incompatible with other air supply paths having different outer peripheral lengths, so it is necessary to reset the arrangement interval of the bar-shaped magnets again and lack general versatility. It was a thing. If the air supply path that is not compatible is attached to the non-conforming air supply path, the intended effect of improving the combustion efficiency cannot be obtained. The combustion improving plate 1 of the present embodiment does not cause such inconvenience at all, and thus has a special advantage compared to the first conventional technique.

(3) In addition, the combustion improving plate 1 of the present embodiment does not use a radioactive substance harmful to the human body as in the second prior art, and therefore has a special effect in terms of safety.

Here, although 1st embodiment is comprised with the sheet metal 1 of 2 sheets, this shows the principle structure of invention, and it is as follows practically. preferable.
<Second Embodiment>
FIG. 3 is a structural diagram of a combustion improving plate according to the second embodiment.
In this figure, (a) shows a state diagram during assembly, and (b) shows a state diagram when assembly is completed. The combustion improving plate 10 has a sandwich structure in which a plurality of metal plates 12 to 15 (here, four as an example) are laminated on an aluminum base 11 and sandwiched by aluminum mesh nets 16 and 17 from above and below. Have. In this figure, the upper aluminum mesh net 16 and the lower aluminum mesh net 17 are depicted as separate bodies. However, the present invention is not limited to this, and an integrated one (a single aluminum mesh net) may be used. Good.

  Similarly to the metal plate 2 of the first embodiment, the metal plates 12 to 15 are made of a highly conductive material (for example, copper, gold, or an alloy containing them), and the plate thickness is easily deformable such as bending. Is taken into account as much as possible (for example, about 0.2 mm). The coating layers 18 to 21 are respectively formed on one side of the metal plates 12 to 15, and these coating layers 18 to 21 are composed of the main component in the same manner as the coating layer 3 of the first embodiment. It consists of subcomponents, and the main component is, for example, a powdery piezoelectric element made of particles of about 3 microns (see piezoelectric element 5 in FIG. 1). The subcomponent (refer to subcomponent 6 in FIG. 1) includes a holding agent for holding the piezoelectric element uniformly, and a conductive agent having a semiconductor property for smoothly moving charges generated in the piezoelectric element. And at least an adhesive (or adhesive) for adhering the piezoelectric element 5, the holding agent, and the conductive agent to the surfaces of the metal plates 12-15.

  Moreover, the conducting wire 22 is drawn out from the metal plates 12 to 15, and the tip of the conducting wire 22 is used by being connected to the ground potential (ground) of the combustion apparatus to be applied.

  The combustion improving plate 10 of this embodiment having such a configuration can also improve the combustion efficiency of the combustion apparatus to be mounted by the same mechanism as that of the combustion improving plate 1 of the first embodiment. .

  That is, the air supply path (see the air supply path 8 in FIG. 2) around which the combustion improving plate 10 of this embodiment is wound is connected to the combustion apparatus, and vibrations associated with the operation of the combustion apparatus are affected by the air supply path. To be told. As described above, since the coating layers 18 to 21 including the powdery piezoelectric elements are formed on the plurality of metal plates 12 to 15 of the combustion improving plate 10, the coating layer 18 is accompanied by the vibration described above. ~ 21, an electromotive voltage is generated by the piezoelectric element. As a result of the electric field generated by the electromotive force acting on the inner wall surface of the air supply path, static electricity generated on the inner wall surface can be canceled out by the electromotive voltage, and the inflow resistance of the air can be reduced to reduce the combustion of the combustion device. The effect can be improved.

  In addition, since the combustion improving plate 10 of this embodiment has a plurality of metal plates 12 to 15 laminated, it corresponds to the total surface area of the metal plates 12 to 15 and the electromotive force generated by the piezoelectric element. Increase can be achieved. That is, in the first embodiment, since the single metal plate 2 is used, the surface area of the metal plate 2 must be increased in order to increase the electromotive voltage by the piezoelectric element. The increase causes an increase in the size of the combustion improving plate 1 and sometimes obstructs the mounting to the combustion apparatus, but a plurality of metal plates 12 to 15 are laminated as in this embodiment. With the configuration, it is possible to obtain a special effect that the electromotive force can be easily increased by the piezoelectric element without increasing the size of the combustion improving plate 10 only by increasing the number of stacked layers.

  Furthermore, since the combustion improving plate 10 of this embodiment is equipped with the aluminum mesh nets 16 and 17 on both sides, when the aluminum mesh nets 16 and 17 are installed in the air supply path of the combustion apparatus, the aluminum mesh nets 16 and 17 are the cushioning material. It is possible to prevent the combustion improving plate 10 from being accidentally displaced or dropped off due to the vibration of the combustion device.

  In the above first and second embodiments, the metal plates 2 and 12 to 15 are made of a highly conductive material made of copper, gold, or an alloy containing them, but in terms of improving combustion efficiency, In particular, it is desirable to use a high-purity copper plate or gold plate (especially a gold plate if the cost permits). Incidentally, you may use gold powder for the electrically conductive agent of the accessory component of the coating-film layers 3 and 18-21.

  Further, it is desirable to increase the number of grounding conductors 4 and 22 or to use a wire (having a single wire or a stranded wire) having a cross-sectional area as large as possible. Similarly, it is because the improvement effect of combustion efficiency increases.

  In the above description, an example in which the combustion apparatus is mounted on the air supply path has been described. However, the present invention is not limited to this. The combustion improving plate 1 of the first embodiment and the combustion improving plate 10 of the second embodiment may be mounted on the exhaust path (exhaust pipe) of the combustion apparatus. In this case, since the exhaust pipe is made of metal, the ground wires (conductive wires 4 and 22) of the combustion improving plate 1 of the first embodiment and the combustion improving plate 10 of the second embodiment are unnecessary. Even in this case, exhaust efficiency can be made smooth and combustion efficiency can be improved.

<Third embodiment>
FIG. 4 is a perspective view of the combustion improving apparatus according to the third embodiment. In this figure, a combustion improving apparatus 100 is used by being attached to an air supply path or a fuel supply path of a combustion apparatus, which will be described later, and is a flexible thin metal plate 101 formed in a belt shape having a predetermined length. And a coating material 102 applied to the contact surface of the metal plate 101.

  As the metal plate 101, flexible thin strip-shaped aluminum or copper is used. As the coating material 102 considered to activate oxygen in combustion air, for example, barium titanate ( Silicon-based paints containing BaTi03) and mixed paints of highly dielectric substances are used.

  The metal plate 101 coated with the coating material 102 is wound around the outer peripheral surface of a curved air supply path (so-called intake pipe) 103 having a large diameter or a small diameter of an engine as an automobile combustion apparatus, for example, and then the metal plate 101 is wound. Is clamped and fixed by a band 104 via a fixture 105.

It is sectional drawing. By preparing the combustion improving apparatus 100 having an appropriate length, the combustion improving apparatus 100 can be wound around the outer peripheral surface of the air supply path of either a large diameter or a small diameter without any trouble.

  FIG. 7 is a perspective view showing a state in which the combustion improving device 110 is attached to the outer peripheral surface of the exhaust passage for discharging exhaust gas from the combustion chamber of the combustion device.

  By activating oxygen in the combustion air by the coating material of the sheet body 111, carbon (C) occupying most (about 87%) of gasoline in the cylinder and hydrogen (about 13%) occupying the rest (about 13%). It is considered that H) is oxidized and the unburned hydrocarbon HC discharged from the exhaust passage 112 is reduced, so that an exhaust gas with less irritating odor can be obtained.

  For example, as an experimental example of unburned hydrocarbons, when a sheet body 111 serving as a combustion improvement device 110 is attached to an exhaust passage 112 of a 1800 cc turbo car using regular gasoline, the HC value before installation is 280 ppm. On the other hand, the HC value could be reduced to 35 ppm after installation.

  Next, the operation of the combustion improving apparatus 100 or the combustion improving apparatus 110 in the present embodiment will be described in detail. When the combustion improving apparatus 100 is attached to the air supply path 103 of the combustion apparatus, the fuel 102 is activated by activating oxygen in the air passing through the air supply path 103 by the coating material 102 applied to the metal plate 101. It is considered that the binding force can be increased to approach complete combustion in the combustion chamber.

  Even when the combustion improving apparatus 100 is attached to a fuel transport pipe (not shown) as a fuel supply path, it is considered that the combustion efficiency can be improved by improving the coupling between the fuel and oxygen.

  Next, an application example of the combustion improving apparatus 100 or the combustion improving apparatus 110 in the present embodiment to an automobile will be described.

In this figure, an automobile 700 shown in an overhead view is equipped with a diesel engine 701, and air is introduced into the diesel engine 701 through an air cleaner 702, an air supply path 703 and a surge tank 704.
