(First embodiment)
FIG. 1 is a diagram schematically showing the configuration of the hydrogen torch 1 according to the first embodiment. In FIG. 1, a cross section is partially shown for convenience of explanation.

  As shown in FIG. 1, the hydrogen torch 1 includes a cylindrical housing 2 and a hydrogen tank 3 that is provided in the housing 2 and supplies hydrogen fuel. Further, the hydrogen torch 1 is provided on the front end surface 7 of the housing 2, and connects the nozzle 4 for ejecting hydrogen fuel in the hydrogen tank 3, the hydrogen tank 3 and the nozzle 4, and the hydrogen fuel in the hydrogen tank 3. Is provided to the nozzle 4, and an adjustment valve 6 that is provided in the hydrogen passage 5 and adjusts the flow rate of the hydrogen fuel supplied from the hydrogen tank 3 to the nozzle 4.

  For example, as shown in FIG. 1, the housing 2 is formed of an elongated cylindrical body. The front end portion and the rear end portion of the housing 2 are closed. For example, the front end of the housing 2 is closed after the components are accommodated therein.

  For example, the housing 2 is configured such that the area of the front end surface 7 of the front end is larger than the area of the rear end surface 8 of the rear end. That is, in the cross section shown in FIG. 1, the housing 2 has an inverted truncated cone shape. In addition, the shape of the housing | casing 2 is not restricted to this.

  In addition, the shape of the housing 2 in the cross section perpendicular to the central axis direction of the housing 2 is not particularly limited. Examples of the shape of the housing 2 in the cross section include a circle, an ellipse, a triangle, a quadrangle, Examples include polygons.

  The hydrogen tank 3 stores hydrogen fuel that serves as the fuel for the hydrogen torch 1. And the form of a hydrogen tank is suitably selected according to the type of hydrogen fuel. When the hydrogen tank stores hydrogen fuel, the hydrogen tank is, for example, a low-pressure tank or a high-pressure tank that contains gaseous hydrogen (hereinafter referred to as hydrogen gas) or liquid hydrogen as hydrogen fuel, or hydrogen fuel. And a tank containing a hydrogen storage alloy that stores gaseous hydrogen.

  As the hydrogen storage alloy, a known hydrogen storage alloy such as a magnesium alloy can be used. Further, a method for releasing hydrogen gas, which is hydrogen fuel, from the hydrogen storage alloy is not particularly limited, and a known release method can be used.

  The nozzle 4 provided on the front end surface 7 of the housing 2 ejects hydrogen fuel supplied from the hydrogen tank 3 through the hydrogen flow path 5 toward the outside of the housing 2. The shape of the nozzle 4 is not particularly limited, but a single-hole nozzle having a single hole at the tip which is the hydrogen fuel outlet, and a plurality of holes at the tip which is the hydrogen fuel outlet. A perforated nozzle or the like can be used. In the case of a multi-hole nozzle, the nozzle tip surface may be closed and an ejection hole may be formed on the side surface on the nozzle tip side. Moreover, it is good also as a nozzle shape which has the cyclic | annular jet nozzle formed of a double pipe.

  The hydrogen flow path 5 connects, for example, the front end surface 7 side of the hydrogen tank 3 and the rear end surface 8 side of the nozzle 4. The hydrogen flow path 5 only needs to be able to supply hydrogen fuel from the hydrogen tank 3 to the nozzle 4, and is configured by, for example, piping.

  The adjustment valve 6 is provided in the hydrogen flow path 5. The configuration of the adjustment valve 6 is not particularly limited as long as the flow rate of the hydrogen fuel supplied from the hydrogen tank 3 to the nozzle 4 through the hydrogen flow path 5 can be adjusted. The adjustment valve 6 includes, for example, a pressure holding valve that keeps the pressure in the hydrogen tank 3 constant and controls the pressure in the hydrogen flow path 5.

  Further, the adjustment valve 6 may be provided inside the housing 2. Moreover, the adjustment part of the adjustment valve 6 may be provided so that a user can adjust directly from the outside. In this case, the adjusting portion of the adjusting valve 6 is exposed to the outside from the side surface of the adjusting valve 6, for example. Furthermore, the adjustment valve 6 may be electronically controlled based on, for example, an output signal from the outside such as a sensor.

  Next, the operation of the hydrogen torch 1 of the first embodiment will be described.

  By adjusting the adjustment valve 6, the hydrogen fuel flowing out of the hydrogen tank 3 and flowing in the hydrogen flow path 5 is adjusted to a desired pressure. The pressure-adjusted hydrogen fuel flows into the nozzle 4 through the hydrogen flow path 5 and is ejected from the tip of the nozzle 4 to the outside of the housing 2. Then, an ignition source is brought close to the downstream side of the nozzle 4 to ignite hydrogen fuel diffused in the air. This causes diffusion combustion due to hydrogen and atmospheric oxygen. A diffusion flame is formed downstream of the nozzle 4.

  As described above, according to the hydrogen torch 1 of the first embodiment, hydrogen gas is used as the hydrogen fuel, and oxygen in the air is used as the oxidant. Therefore, a clean hydrogen torch that does not discharge fine particles such as carbon dioxide and soot can be provided.

  In the hydrogen torch according to the first embodiment, since no liquid fuel is used, a mechanism for spraying the liquid fuel becomes unnecessary. Furthermore, since the hydrogen fuel of the hydrogen torch is hydrogen gas, danger such as blockage of the fuel flow path can be avoided.

(Second Embodiment)
FIG. 2 is a diagram schematically showing the configuration of the hydrogen torch 1a of the second embodiment. In the following embodiment, the same components as those of the hydrogen torch 1 of the first embodiment are denoted by the same reference numerals, and redundant description is omitted or simplified.

  The hydrogen torch 1a of the second embodiment is basically the same as the configuration of the hydrogen torch 1 of the first embodiment, except that the configuration of the hydrogen tank is different. Therefore, here, the different configuration will be mainly described.

  The hydrogen tank 13 provided in the housing 2 of the hydrogen torch 1a of the second embodiment has a configuration that generates hydrogen gas as hydrogen fuel using hydrolysis inside the hydrogen tank 13. The hydrogen tank 13 includes a water tank 13a that contains and supplies water, and a hydrogen generation tank 13b that is connected to the water tank 13a and generates hydrogen fuel by a hydrolysis reaction with water supplied from the water tank 13a.

  The water tank 13a contains water. For example, the water tank 13a is provided closer to the distal end surface 7 side of the housing 2 than the hydrogen generation tank 13b.

  The hydrogen tank 13 includes a water flow path 15 that connects the rear end face 8 side of the water tank 13a and the front end face 7 side of the hydrogen generation tank 13b. The water channel 15 supplies the water in the water tank 13a to the hydrogen generation tank 13b. The water flow path 15 is comprised by piping etc., for example.

  The water flow path 15 includes a water adjustment valve 16. The water adjustment valve 16 adjusts the flow rate of water supplied from the water tank 13a to the hydrogen generation tank 13b by gravity. The configuration of the water adjustment valve 16 is not particularly limited as long as the flow rate of water supplied from the water tank 13a to the hydrogen generation tank 13b through the water flow path 15 can be adjusted.

  In addition, the water adjustment valve 16 may be provided so that the user can directly adjust from the outside, like the adjustment valve 6 described above. Further, the water adjustment valve 16 may be electronically controlled based on an output signal from the outside such as a sensor.

  In the hydrogen generation tank 13b, hydrogen is generated by a hydrolysis reaction with water. The hydrogen generation tank 13b is provided on the rear end face 8 side of the housing 2 with respect to the water tank 13a, for example. The hydrogen generation tank 13b contains a compound that generates a hydrogen gas by causing a hydrolysis reaction.

The hydrogen gas generated in the hydrogen tank 13 is supplied to the nozzle 4. And as mentioned above, it is ignited by the ignition source, and a diffusion flame is formed downstream of the nozzle 4.

  In a state where the hydrogen torch 1a is not used, an appropriate amount of water may be supplied to the hydrogen generation tank 13b to generate hydrogen in the hydrogen generation tank 13b in advance. In this case, with the adjustment valve 6 closed, an appropriate amount of water is supplied to the hydrogen generation tank 13b, and then the water adjustment valve 16 is closed. In this case, the pressure in the hydrogen generation tank 13b increases due to the generated hydrogen. Therefore, the amount of water supplied to the hydrogen generation tank 13b is adjusted so that the amount of hydrogen generated is equal to or lower than the pressure that the hydrogen torch can withstand.

  As described above, according to the hydrogen torch 1a of the second embodiment, the water supplied from the water tank to the hydrogen generation tank and the compound accommodated in the hydrogen generation tank cause a hydrolysis reaction, and hydrogen fuel As a result, hydrogen gas can be generated. Therefore, the hydrolysis reaction can be controlled by adjusting the flow rate of water with the water adjustment valve, and the amount of hydrogen fuel produced can be adjusted.

  As described above, according to the hydrogen torch 1b of the third embodiment, the temperature of the hydrogen tank can be appropriately controlled by providing the heater portion around the hydrogen tank. Therefore, it is possible to suppress a decrease in the temperature of the hydrogen tank that occurs when the hydrogen gas is released from the hydrogen tank, and it is possible to prevent a decrease in the hydrogen supply amount of the hydrogen tank. Furthermore, when the hydrogen torch has a configuration that generates hydrogen fuel using a hydrolysis reaction, the temperature of the hydrogen generation tank that generates the hydrolysis reaction can be controlled by the heater, so that the hydrogen generation of the hydrogen generation tank The amount can be controlled.

  Furthermore, before the torch runner runs, the input terminal portion 34 and the external power source are connected in advance, the heater portion 33 is heated, and when the torch runner runs, the external power source is disconnected from the input terminal portion 34. In this case, the hydrogen torch does not require a battery for heating the heater unit 33, and the hydrogen torch becomes light. Furthermore, as compared with the battery, the external power source can heat the heater unit in a short time.

  In addition, since hydrogen gas is used as the hydrogen fuel and oxygen in the air is used as the oxidant, a clean hydrogen torch that does not discharge particulates such as carbon dioxide and soot can be provided.

The heat of the heated heat transfer member 144 is transmitted to the adjacent air flow path 145, and the air in the air flow path 145 is heated. When the air in the air flow path 145 is heated, an updraft is generated in the air flow path 145. That is, the air is introduced from the end on the rear end face 8 side of the air flow path 145, and the air introduced into the air flow path 145 is discharged from the end of the air flow path 145 on the front end face 7 side.

As shown in FIG. 19, when the shutoff valve 178 is provided between the regulating valve 6 and the nozzle 4, the amount of hydrogen fuel supplied to the nozzle 4 after closing the shutoff valve 178 is small, and the flame of the hydrogen torch 1s. 9 can be killed faster.

  Next, the operation of the hydrogen torch 1s according to the eighteenth embodiment will be described.

  When the acceleration change occurs in the hydrogen torch 1s due to the torch runner falling, the acceleration detection unit 173 detects the acceleration change of the hydrogen torch 1s. When the acceleration detection unit 173 detects the acceleration change of the hydrogen torch 1 s, the control unit 174 receives acceleration data from the acceleration detection unit 173. When the acceleration change generated in the hydrogen torch 1s exceeds a predetermined value, the control unit 174 closes the shut-off valve 178 and closes the hydrogen flow path 5, stops the supply of hydrogen fuel to the nozzle 4, and the hydrogen torch Force 1s flame 9 to extinguish.

  As described above, according to the hydrogen torch 1s of the eighteenth embodiment, when a predetermined acceleration change occurs in the hydrogen torch, the hydrogen fuel supplied to the nozzle is forcibly cut off. Therefore, when the torch runner falls, the flame of the hydrogen torch is extinguished, and the torch runner and surrounding flames can be prevented from being injured.

  In addition, since hydrogen gas is used as the hydrogen fuel and oxygen in the air is used as the oxidant, a clean hydrogen torch that does not discharge particulates such as carbon dioxide and soot can be provided.

(Nineteenth embodiment)
FIG. 20 is a diagram schematically illustrating the configuration of the hydrogen torch 1t according to the nineteenth embodiment.

  The hydrogen torch 1t according to the nineteenth embodiment is basically the same as the configuration of the hydrogen torch 1 according to the first embodiment, except that a gripping detection unit and a shutoff valve are provided. Therefore, here, the different configuration will be mainly described.

  The hydrogen torch 1t according to the nineteenth embodiment includes a grip detection unit 183 that detects that the grip part of the hydrogen torch 1t is gripped, and a shutoff valve 188 provided in the hydrogen flow path 5. The shutoff valve 188 shuts off the hydrogen fuel supplied from the hydrogen tank 3 to the nozzle 4. The configuration of the shutoff valve 188 may be the same as or different from the configuration of the shutoff valve 168 described above.

  Further, the hydrogen torch 1 t includes a control unit 184 that closes the shutoff valve 188 and closes the hydrogen flow path 5 based on the output from the grip detection unit 183. In addition, the grip detection unit 183, the control unit 184, and the shutoff valve 188 are connected via a wiring 185.

  The grip portion is a portion where the torch runner grips the hydrogen torch 1t, and is generally a side surface of the housing 2. Here, as illustrated in FIG. 20, the gripping unit is a gripping detection unit 183.

  Next, the operation of the hydrogen torch 1t according to the nineteenth embodiment will be described.

  When the torch runner is gripping the grip detection unit 183 that is the grip of the hydrogen torch 1t, the shutoff valve 188 is energized and the shutoff valve 188 is open. When the torch runner releases the hydrogen torch 1t due to a fall or the like, the control unit 184 shuts off the electric supply to the shutoff valve 188, and the shutoff valve 188 is closed. Then, the hydrogen flow path 5 is closed, the supply of hydrogen fuel to the nozzle 4 is stopped, and the flame 9 of the hydrogen torch 1t is forcibly extinguished.

  As described above, according to the hydrogen torch 1t of the nineteenth embodiment, when the hydrogen torch held by the torch runner is released, the hydrogen fuel supplied to the nozzle is forcibly shut off. Therefore, when the torch runner falls, the flame of the hydrogen torch is extinguished, and the torch runner and surrounding flames can be prevented from being injured.

  In addition, since hydrogen gas is used as the hydrogen fuel and oxygen in the air is used as the oxidant, a clean hydrogen torch that does not discharge particulates such as carbon dioxide and soot can be provided.

(20th embodiment)
FIG. 21 is a diagram schematically illustrating the configuration of the hydrogen torch 1u according to the twentieth embodiment.

  The hydrogen torch 1u according to the twentieth embodiment is basically the same as the configuration of the hydrogen torch 1 according to the first embodiment, except that a mesh-like flame reactant is provided. Therefore, here, the different configuration will be mainly described.

  The hydrogen torch 1u according to the twentieth embodiment includes a mesh-like flame reactant 194 having a through-hole 194a penetrating along the central axis direction of the housing 2. The through hole 194 a of the flame reaction body 194 is fitted to the tip of the nozzle 4, and the flame reaction body 194 extends along the central axis direction of the housing 2. The flame reaction body 194 is, for example, an annular cylinder. Further, the flame reactant 194 causes a flame reaction by the flame 9 a formed downstream of the nozzle 4.

  The flame reactant 194 is provided on the nozzle 4 on the downstream side of the front end surface 7 of the housing 2. Further, since the flame reactant 194 is fixed to the nozzle 4 through the through hole 194a, the flame reactant 194 does not block the nozzle 4. The flame reaction body 194 is fixed to the nozzle 4 by, for example, a screw (not shown).

  The flame reactant 194 is symmetric with respect to the central axis direction of the housing 2, for example. Here, as shown in FIG. 21, an example in which the inner diameter of the flame reaction body 194 is constant along the central axis direction of the housing 2 is shown, but the inner diameter of the flame reaction body 194 may not be constant. . The inner diameter of the flame reactant 194 may increase or decrease from one end to the other end of the flame reactant 194 on the side fitted to the nozzle 4.

  Here, as shown in FIG. 21, an example in which the inner periphery of the flame reaction body 194 is fitted to the outer periphery of the tip portion of the nozzle 4 through the through hole 194 a is shown. The outer periphery may be fitted to the inner periphery of the tip of the nozzle 4.

  Moreover, the flame reactant 194 has a mesh shape and has a through-hole (not shown) in a direction perpendicular to the central axis direction of the housing 2. In addition, the shape of the mesh of the flame reactant 194 is not particularly limited, and examples thereof include a lattice shape.

  The flame reaction body 194 includes a mesh-shaped carrier 195 and a flame reaction material 196 that is formed on the surface of the carrier 195 and causes a flame reaction by the flame 9a of the hydrogen torch 1u.

  The carrier 195 carrying the flame reaction material 196 has a mesh shape. The substance constituting the carrier 195 is not particularly limited as long as it does not react with the flame 9a and can maintain the shape of the flame-colored reactant 194 even when heated by the flame 9a. The carrier 195 is made of an alloy such as stainless steel or hastelloy.

  The flame reaction material 196 carried on the surface of the carrier 195 is made of a material that causes a flame reaction by the flame 9a of the hydrogen torch 1u. The flame reaction material 196 is made of, for example, a compound such as sodium chloride, lithium oxide, or boric acid, or a simple metal such as indium. In addition, the flame reaction material 196 may be composed of one kind of material or may be composed of two or more kinds of materials.

  The method for producing the flame reactant 194 is not particularly limited. For example, after applying the flame reaction material 196 to the surface of the carrier 195, the carrier 195 coated with the flame reaction material 196 is heated at a predetermined temperature and heat-treated, and the flame reaction material 196 is baked. A flame reactant 194 is produced. By burning the flame reaction material 196 on the carrier 195, it is possible to suppress the flame reaction material 196 from being scattered outside the hydrogen torch 1u even when the flame 9a is formed. That is, peeling of the flame reaction material 196 from the carrier 195 can be suppressed.

  The flame reaction material 196 may be applied to the carrier 195 by applying powder obtained by pulverizing the flame reaction material 196 or by dissolving the flame reaction material 196 in a predetermined solvent. The resulting solution may be applied.

  The firing temperature of the flame reaction material 196 is appropriately selected according to the material constituting the flame reaction material 196. Regarding firing of the flame reaction material 196, the carrier 195 coated with the flame reaction material 196 may be heat-treated in an electric furnace, or may be heat-treated with the flame 9a.

  The amount of the flame reaction material 196 constituting the flame reaction material 194 is not particularly limited as long as the flame 9a is formed for a desired time. For example, when the flow rate of the supplied hydrogen fuel is 5 L / min and the amount of the flame reaction material 196 is 30 mg, the flame 9a is formed for 20 minutes.

  The hydrogen torch 1u may be provided with a cylindrical surrounding member (not shown) that surrounds the base of the flame 9a. This surrounding member prevents the flame 9a from a cross wind from the outside of the hydrogen torch 1u.

  Next, the operation of the hydrogen torch 1u according to the twentieth embodiment will be described.

  Hydrogen fuel flowing out of the hydrogen tank 3 and flowing in the hydrogen flow path 5 flows into the nozzle 4 and is ejected from the tip of the nozzle 4 to the outside of the housing 2. And as mentioned above, it is ignited by the ignition source, and a diffusion flame is formed downstream of the nozzle 4. The flame reaction of the flame reactant 194 is caused by the heat of the flame 9a of the hydrogen torch 1u. Since the flame reactant 194 reacts with the flame 9a of the hydrogen torch 1u, light having a wavelength in the visible region is emitted, and the flame 9a of the hydrogen torch 1u has a color corresponding to the material constituting the flame reactant 194. Colored.

  As described above, according to the hydrogen torch 1u of the twentieth embodiment, a flame reaction body that causes a flame reaction by a flame formed downstream of the nozzle is provided at the tip of the nozzle. Therefore, the flame of the hydrogen torch can be colored in an arbitrary color by appropriately selecting the material constituting the flame color reactant.

  Further, the flame reactant 194 fitted to the tip of the nozzle 4 does not block the nozzle 4. Therefore, the hydrogen torch 1u can form a flame 9a having an increased flame height. Therefore, the flame reaction material 196 can be prevented from being scattered outside the hydrogen torch 1u during the formation of the flame 9a, so that the formation time of the flame 9a can be further increased.

  In addition, since hydrogen gas is used as the hydrogen fuel and oxygen in the air is used as the oxidant, a clean hydrogen torch that does not discharge particulates such as carbon dioxide and soot can be provided.

  According to the embodiment described above, it is possible to provide a clean hydrogen torch that does not discharge fine particles such as carbon dioxide and soot.
