Description

  The present invention forms a magnetic field in a power generation channel for the flow of a conductive fluid, and a first conductive member and a second conductive member are arranged at intervals in the power generation channel to form the magnetic field. The conductive fluid is caused to flow through the generated power generation flow path, and the first conductive member and the second conductive member are short-circuited with the conductive fluid to short-circuit the first conductive member and the second conductive member. The present invention relates to a power generation method and a power generation apparatus that extract an induced current from a conductive member.

  In this type of apparatus, for example, a pair of magnetic poles opposed to each other in a direction orthogonal to the flow direction of the conductive fluid, and the flow direction and the pair of magnetic poles in a power generation flow path for the flow of the conductive fluid A pair of electrodes that are opposed to each other in a direction orthogonal to the opposite direction is arranged. A current is taken out by the pair of electrodes by causing the conductive fluid to flow in such a power generation channel in a direction perpendicular to the magnetic field lines generated between the pair of magnetic poles.

For example, in patent document 1, the said power generation flow path is formed in a part of flow path which circulates a conductive fluid. In this flow path, a rare gas to which a seed material such as Na or K that is easily ionized by heat and becomes highly conductive is added as a conductive fluid. The seed material added to the rare gas is ionized in a high temperature state where the rare gas is heated by a heat source arranged in the flow path, and becomes highly conductive. A noble gas in a high temperature state to which such a highly conductive seed material is added is continuously flowed to the power generation flow path by the circulation as a conductive fluid to generate power.
Japanese Patent Publication No. 6-11183 (FIGS. 1 to 3)

  However, in the above-described device of Patent Document 1, since the flow of a high-temperature noble gas to the power generation flow path of the conductive fluid is continuously performed, the device continuously receives heat from the noble gas. Since the wall surface forming the power generation flow path is heated to a high temperature state, the durability becomes low, and it is necessary to configure the apparatus using a large amount of refractory, resulting in an increase in equipment cost. In addition, since the electrode disposed in the power generation channel is generally a highly conductive and inexpensive metal, such as copper or an alloy thereof, such a metal is likely to burn out in the high temperature environment as described above. As a result, the repair cost becomes high.

  In addition, in an environment where the apparatus is maintained at a high temperature for a long time as described above, in general, a fluid that is easily ionized has high reactivity, so that the apparatus may be damaged in the flow path of the conductive fluid. Since it is easy to produce an undesirable chemical reaction, it cannot be used as a conductive fluid. Therefore, in the apparatus of the above-mentioned Patent Document 1, a rare gas is caused to flow in the flow path. As a result, the rare gas is difficult to ionize, so a seed material is required and the cost is increased.

  Also, in order to obtain the maximum amount of power by taking out the current in the entire area of the power generation flow path, magnetic poles and electrodes must be arranged over the entire area of the power generation flow path in the flow direction of the conductive fluid in the power generation flow path. The cost is high because it is not necessary. Further, when a permanent magnet is used as the magnetic pole, the magnetic field leaks out of the apparatus and adversely affects the surrounding electrical equipment. Therefore, the apparatus of Patent Document 1 requires a large-scale electromagnet, resulting in a high construction cost.

Therefore, the present invention is a low-cost device that does not require a seed material without providing a large-scale electrode and magnet, while extending the life of the device without using a large amount of refractories and reducing the equipment cost and repair cost. An object of the present invention is to provide a power generation method and a power generation apparatus capable of realizing costly power generation with low construction costs.

  Furthermore, an object of the present invention is to provide a power generation method and a power generation apparatus capable of producing a useful substance by further effectively using high energy remaining in a conductive fluid after the power generation in addition to the power generation.

  In this application, regarding the power generation method, a seed material is required while extending the life of the device and reducing the equipment cost and the repair cost without increasing the temperature of the device continuously for a long time and without using a large amount of heat-resistant material. The first invention is proposed as a method capable of realizing low-cost power generation with low construction costs. In addition to the power generation in the first aspect of the present application, the present application aims to further effectively use the high energy of the shock wave of the combustion gas used as a conductive fluid for the power generation, and contains hydrogen-containing gas or carbon as a useful substance. The second invention is proposed as a method capable of producing gas. Further, in the present application, in addition to the power generation in the first invention, the high energy remaining in the combustion gas after the power generation is effectively utilized to perform additional power generation in at least one of the gas turbine and the steam turbine. The third invention is proposed as a method that enables highly efficient power generation.

  The present application also relates to a power generator, the fourth invention as an apparatus for carrying out the first invention, the fifth invention as an apparatus for carrying out the second invention, and an apparatus for carrying out the third invention. The sixth invention is proposed as follows.

<First invention>
A power generation method according to a first aspect of the present invention is to form a magnetic field in a power generation flow path for the flow of a conductive fluid, and to arrange the first conductive member and the second conductive member in the power generation flow path with a space between each other. Then, a conductive fluid is caused to flow through the power generation channel in which the magnetic field is formed, and the first conductive member is short-circuited between the first conductive member and the second conductive member by the conductive fluid. The current is taken out by the member and the second conductive member.

  In this method, in the first invention, as a characteristic of the configuration of the first conductive member and the second conductive member, the first conductive member and the second conductive member are in the flow direction of the conductive fluid in the power generation flow path. Are arranged with overlapping ranges. The first conductive member is formed as a coil disposed in the power generation flow path, and the coil is disposed such that an axis of the coil extends in the flow direction.

Along with the expansion of the short circuit range, the inductance of the coil and the second conductive member decreases on the downstream side of the short circuit range. An induced current is generated in the coil so as to form the magnetic field. However, since the inductance of the coil is reduced, the induced current is increased beyond the initial current.
Since the magnetic field of the coil increases due to the increase of the induced current, the induced current further increases. The induced current thus increased is taken out at the downstream end. Here, detonation refers to a phenomenon in which a flame propagates at supersonic speed with a shock wave.

  In the combustion chamber, it is preferable that the cross-sectional area of the flow path gradually decreases toward the power generation flow path. In this way, the shock wave of the combustion gas is converged in the combustion chamber where the cross-sectional area of the flow path gradually decreases, and the high temperature and pressure are further increased, so the degree of dissociation or ionization of the combustion gas when introduced into the power generation flow path is improved, As a result, the power generation efficiency is significantly increased.

  Further, by repeatedly and intermittently generating detonation, a pulse current can be repeatedly obtained at the downstream end. Further, such a pulse current can be converted to AC power by a capacitor and an inverter.

The second conductive member is formed of a conductive material that extends in the flow direction with a spacing from the coil and is disposed in the power generation flow path. Further, the magnetic field forming means is a closed circuit formed by connecting the upstream ends of the coil and the second conductive member to each other via a DC power source and electrically connecting the downstream ends of the coils and the second conductive member. The circuit is configured so that an initial current is previously generated in the closed circuit by the DC power source to form a magnetic field in the power generation flow path. Further, the power generation channel communicates with the combustion chamber connected to the ignition chamber that receives the supply of fuel on the upstream side of the power generation channel.

  In the fourth invention having such a feature, the combustion gas dissociated or ionized by detonation flows into the power generation flow path as a conductive fluid and is guided at the downstream end as in the first invention. Current is taken out.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a diagram showing a schematic configuration of the apparatus according to the present embodiment.

  As shown in FIG. 1, the apparatus according to this embodiment includes a detonation generator 10 that generates detonation by dissociating or ionizing detonation by intermittent combustion of fuel, and uses the combustion gas as a conductive fluid. The power generation apparatus 20 that receives and generates electric power, the reaction apparatus 30 that generates a carbon dioxide decomposition reaction by receiving a shock wave of combustion gas, and the gas turbine 40 that generates electric power using the combustion exhaust gas of the detonation generator 10 are mainly provided. ing. Therefore, the function of the present embodiment apparatus is roughly divided into a power generation function in the power generation apparatus 20, a power generation function in the gas turbine 40, and a carbon-containing gas production function by a carbon dioxide decomposition reaction in the reaction apparatus 30. Is done. Here, the apparatus of the present embodiment uses the energy of the shock wave of the combustion gas after the power generation in the function of producing the carbon-containing gas in the reactor 30 together with the power generation in the power generation apparatus 20, and the gas turbine 40 The power generation function uses the energy of the combustion gas discharged as exhaust gas from the detonation generator 10 after the power generation. Hereinafter, the detonation generator 10, the gas turbine 40, the power generator 20, and the reactor 30 will be described in this order.

As shown in FIG. 1, the detonation generator 10 is connected to a fuel supply device 11 that supplies fuel to the detonator 10. In the fuel supply device 11, the amount of fuel supplied to the detonation generating device 10 can be adjusted by a control valve 11A. The detonation generator 10 receives preheated air of about 400 ° C. from a heat exchanger 41, which will be described later, as an oxidant for burning the fuel, and the preheated air is supplied to the detonator 10 as combustion air. Is connected to the preheated air supply device 12. Since the combustion air is preheated and has high reactivity with the fuel, an inexpensive low-quality fuel can be used, and the detonation generator 10 can be downsized.

  As shown in FIG. 2, the detonation generator 10 includes an ignition chamber 13 that receives supply of fuel and preheated air, and a combustion chamber 14 that communicates with the ignition chamber 13.

  The ignition chamber 13 is formed in a cylindrical shape, and one end of the ignition chamber 13 is provided with an ignition plug 13A as an ignition device for igniting the fuel intermittently. The ignition chamber 13 is provided with a shellkin spiral 13 </ b> B made of a spiral metal extending in the axial direction of the ignition chamber 13. The shellkin spiral 13B accelerates the flame generated when the fuel is ignited by the spark plug 13A. Furthermore, the ignition chamber 13 is provided with two pressure sensors 13C that are spaced apart in the axial direction. These two pressure sensors 13C detect the passage timing of the flame in the ignition chamber 13, respectively, and the pressure on the downstream side from the flame passage timing at the upstream pressure sensor in the flame traveling direction is measured by a measuring means (not shown). The progress speed of the flame in the ignition chamber 13 is measured based on the relationship between the time required for the flame to pass through the sensor and the distance between the two pressure sensors. Based on the flame speed, the ignition timing of the spark plug 13A and the fuel supply amount of the control valve 11A are controlled by a control means (not shown), and the detonation start position is adjusted to the optimum position. . Further, when soot accumulation or the like occurs in the ignition chamber 13, abnormal combustion occurs. Therefore, it is possible to detect abnormal combustion due to soot accumulation or the like at an early stage based on the traveling speed of the flame.

  The other end of the ignition chamber 13 communicates with the dispersion chamber 15. The dispersion chamber 15 communicates from the dispersion chamber 15 to a plurality of positions on the introduction side end portion 14A that is slightly curved in the combustion chamber 14 by a guide passage 16 so that the path lengths are equal to each other.

  The combustion chamber 14 has a conical shape in which the cross-sectional area in the cross section perpendicular to the axis is directed to the right in FIG. 2, and this cross-sectional area is maximum at the introduction end 14A. A minimum convergence portion is formed at the outlet opening end portion 14B at the right end portion. A plurality of detonation waves introduced from the induction path 16 into the combustion chamber 14 are converged, and a high-temperature high-pressure convergent detonation wave is formed. The combustion chamber 14 is connected to the power generation device 20 at the outlet opening end portion 14B of the combustion chamber 14, and detonated or ionized by causing detonation by intermittent combustion of the fuel ignited in the ignition chamber 13. Combustion gas flows into the power generator 20 (see FIG. 1). In addition, the combustion chamber 14 has a conical shape, and the flow passage cross-sectional area gradually decreases in three dimensions to form a converging portion. However, the combustion chamber 14 has a substantially triangular prism shape, and the flow passage cross-sectional area gradually decreases in two dimensions. Thus, a convergence portion may be formed. By doing so, the time for which the combustion gas is dissociated or ionized and continues as a conductive fluid is lengthened, and as a result, the power generation time is increased, and the power generation amount and the power generation efficiency can be improved.

  In the present embodiment, the ignition chamber 13 and the combustion chamber 14 are provided with a jacket for cooling the inner walls of the ignition chamber 13 and the combustion chamber 14 to maintain the temperature below a predetermined temperature, for example, a water cooling jacket 17 (17A, 17B and 17C). Is formed. The water cooling jacket 17 maintains the temperature of the inner walls of the ignition chamber 13 and the combustion chamber 14 below the ignition temperature of the fuel, and the ignition chamber 13 and the combustion chamber 14 are caused by overheating of the inner walls of the ignition chamber 13 and the combustion chamber 14. To prevent abnormal combustion.

Further, in the vicinity of the outlet opening end portion 14B of the combustion chamber 14, an exhaust port 18 for discharging the combustion exhaust gas of the combustion chamber 14 after the combustion gas flows to the power generation device 20 is formed. The exhaust port 18 is connected to a gas turbine 40 that generates power by being driven by the combustion exhaust gas via a control valve 18A shown in FIG. 1 (see FIG. 1).

  As shown in FIG. 1, the gas turbine 40 is connected to a heat exchanger 41, and the heat exchanger 41 performs heat exchange between combustion exhaust gas after driving the gas turbine 40 and air from the outside. The preheated air for the above-mentioned preheated air supply device 12 is generated by raising the temperature. The heat exchanger 41 is connected to an exhaust gas treatment device 42 that detoxifies the combustion exhaust gas after heat exchange in the heat exchanger 41 and dissipates it into the atmosphere.

Further, assuming that the ratio of the fuel and air supplied to the detonation generator 10 is an air shortage condition rather than the theoretical mixing ratio, the combustion exhaust gas from the detonator 10 and the preheated air from the preheated air supply device 12 are gasified. The gas turbine 40 may be driven to generate electric power by supplying it to a combustor (not shown) of the turbine 40 and burning them. By doing so, it is possible to reduce the generation amount of the NO _X generated in the detonation generator 10, electric power can be generated by effectively utilizing further unburned flue gases.

Further, when there is an oxygen production plant such as an ironworks, oxygen may be supplied to the detonation generator 10 instead of preheated air. This can reduce the NO _X generation by N content in the air, the apparatus can be made compact.

  As shown in FIG. 3, the power generation device 20 communicating with the detonation generating device 10 communicates with the combustion chamber 14 at the outlet opening end portion 14B, and has a tubular shape for the flow of conductive fluid. A power generation channel 21 is provided. In the power generation channel 21, the coil 23 as the first conductive member and the second conductive member 24 overlap each other in the direction in which the axis 22 of the power generation channel 21 extends (the flow direction of the conductive fluid). It is arranged with.

  The coil 23 extends so that the axis of the coil 23 coincides with the axis 22 of the power generation channel 21, and is attached to the peripheral wall of the power generation channel 21 via an insulating material 25.

  The second conductive member 24 is formed of a rod-shaped conductive material disposed on the axis 22, and is disposed in the power generation passage 21 with a radial interval with respect to the coil 23. The second conductive member 24 is supported by the insulating material 25 via an attachment member 24A attached to the downstream end of the second conductive member 24.

  In the present embodiment, the second conductive member 24 has an area in a cross section perpendicular to the axis 22 in the flow direction of the conductive fluid in the power generation channel 21 from the upstream (hereinafter simply referred to as upstream) to the downstream (hereinafter referred to as upstream). It is gradually increasing toward the downstream). Accordingly, the flow resistance of the second conductive member 24 with the conductive fluid sent toward the upstream end of the second conductive member 24 is reduced. In addition, the coil 23 and the second conductive member 24 are hollow, and a cooling liquid such as water is flowed through the hollow portion, and the temperature rises due to heat from a high-temperature conductive fluid. It is preferable that prevention is achieved.

The upstream end portions (left end portions in FIG. 3) of the coil 23 and the second conductive member 24 are connected to each other via a DC power supply 26. On the other hand, a capacitor 27, an inverter 28, and a load 29 are connected in order to the downstream end portions (the right end portion in FIG. 3) of each of the coil 23 and the second conductive member 24. Thus, the coil 23, the second conductive member 24, the DC power supply 26, the capacitor 27, the inverter 28, and the load 29 form a closed circuit, and the coil 23 is driven by a current flowing in the closed circuit. The magnetic field generating means for forming a magnetic field in the power generation flow path 21 is configured. That is, in this closed circuit, when the combustion gas as the conductive fluid does not flow from the detonation generating device 10 to the power generation passage 21, the DC power source 26 generates an initial current in the closed circuit, and A magnetic field is formed from the coil 23 to the power generation channel 21. When the combustion gas flows from the detonator 10 to the power generation channel 21, the combustion gas traveling from the upstream side to the downstream side of the power generation channel 21 establishes a gap between the coil 23 and the second conductive member 24. Shorted. The short-circuit range is such that the downstream end of the combustion gas as the conductive fluid proceeds from upstream to downstream, so that the upstream end of each of the coil 23 and the second conductive member 24 is directed toward the downstream end. Enlarged. Thus, since the short circuit range is expanded, the inductance of the coil 23 and the second conductive member 24 is decreased on the downstream side of the short circuit range. An induced current is generated in the coil 23 so as to form the magnetic field. However, since the inductance of the coil 23 is reduced, the induced current is increased beyond the initial current. Since the magnetic field of the coil 23 increases due to the increase of the induced current, the induced current further increases. Such an induced current is obtained at the downstream end as a pulse current.

  The capacitor 27 and the inverter 28 convert the pulse current into an alternating current and supply it to the load 29.

  In addition, when the X-ray, electron beam, and inertial fusion generator is used as a load, the pulse current is taken out without providing the capacitor 27 and the inverter 28, and the pulse current is directly supplied to the generator. May be.

  Further, by increasing the plate thickness, width, or strand diameter on the downstream side of the coil 23 from the upstream side, when the short circuit range is expanded toward the downstream side, the inductance of the coil 23 is greatly reduced. The induced current generated in the coil 23 can be increased.

  Further, the flow passage cross-sectional area may gradually decrease toward the downstream side of the power generation passage 21 of the power generation apparatus 20, and the diameter of the coil 23 may gradually decrease toward the downstream side. Also by this, when the short circuit range is expanded toward the downstream side, the inductance of the coil 23 is further reduced, so that the induced current generated in the coil 23 can be increased.

  Further, as a direct current power source 26 for generating an initial current in the coil 23 in order to form a magnetic field in the power generation flow path 21, it is necessary to use a steady current if the power stored in the capacitor is instantaneously supplied to the coil 23. It is possible to save energy and make the device compact.

  As shown in FIG. 1, the reaction device 30 connected to the power generation flow path 21 of the power generation device 20 includes, on the inlet side, a reactant supply device 31 that supplies carbon dioxide as a reactant to the reaction device 30. And a buffer tank 32 for receiving the reaction product gas from the reaction apparatus 30 is connected to the outlet side.

  As shown in FIG. 1, the reactant supply device 31 controls the supply amount of the reactant to the reactor 30 to a predetermined amount by opening / closing control of a control valve 31A. In addition, as shown by the broken line in FIG. 1, the reactant supply device 31 replaces carbon dioxide as a reactant with waste plastic or waste oil containing hydrocarbons, or waste activated carbon containing carbon. You may make it supply to the said reactor 30. FIG. When such a substance containing hydrocarbon or carbon is employed as a reactant, water vapor in the combustion gas reacts with hydrocarbon or carbon in the reactant to generate a hydrogen-containing gas. In this case, if a steam supply device 33 that supplies steam to the reaction device 30 is connected to the inlet side of the reaction device 30 as shown by a broken line in FIG. 1, for example, the hydrogen production reaction is promoted.

  Next, based on FIG. 4, the reaction apparatus 30 concerning this embodiment is demonstrated in detail.

  4A is a diagram showing a schematic configuration of the reaction apparatus 30, and FIG. 4B is a cross-sectional view taken along the line BB in FIG. 4A.

  As shown in FIGS. 4 (A) and 4 (B), the reaction device 30 is arranged at a plurality of positions in the circumferential direction on a rotating body 35 that rotates about an axis 34 extending in the lateral direction in FIG. 4 (A). A reaction chamber 35 </ b> A that extends in parallel to the axis 34 and opens at both ends in the axial direction of the rotating body 35 is formed. Each reaction chamber 35 </ b> A is a space for reacting a reactant using the shock wave energy of the combustion gas from the detonation generator 10 after receiving the reactant supply from the reactant supply device 31. is there. In the reaction chamber 35A, the reactant is shock-compressed by a shock wave of the combustion gas to a high temperature, thereby causing a decomposition reaction of carbon dioxide to generate a carbon-containing gas.

  Lid-like opening and closing members 36 and 37 are arranged in a non-rotating manner at a position facing both end faces of the rotating body 35 with a minute gap with respect to the end face so as to allow the rotating body 35 to rotate. The opening / closing members 36 and 37 and the peripheral surface of the end portion of the rotating body 35 are sealed by a seal member 38 while allowing their relative rotation. Moreover, you may use a labyrinth seal, an oil seal, or a water seal device as a seal.

  On the supply side (left side in FIG. 4A), the opening / closing member 36 has one supply opening 36A that communicates with the above-described reactant supply device 31 at a position facing each other in the radial direction of the rotating body 35, and One shock wave introduction opening 36 </ b> B that can communicate with the power generation flow path 21 of the power generation apparatus 20 is formed.

  Further, the discharge side opening / closing member 37 (on the right side in FIG. 4A) has one discharge port 37A that communicates with the buffer tank 32 shown in FIG. The discharge port 37A constitutes a discharge means for discharging the reaction product gas in the reaction chamber 35A, and the discharge port 37A is opened and closed by a control valve 37B as seen in FIG. Yes. The positional relationship between the discharge port 37A, the supply opening 36A, and the shock wave introduction opening 36B will be described below.

  As shown in FIG. 4, the rotating body 35 is rotatably supported by a support member 39 such as a bearing, and the opening of each reaction chamber 35A is sequentially aligned with the supply opening 36A by a driving means (not shown). It is rotated intermittently so as to communicate. That is, in this embodiment, since eight reaction chambers 35A are formed in the rotator 35, the rotator 35 rotates intermittently by 45 °, and the openings of the reaction chambers 35A are sequentially opened to the supply openings 36A. Matches.

  Specifically, when the rotation of the rotating body 35 causes the opening of one reaction chamber 35A of the plurality of reaction chambers to coincide with the supply opening 36A, the one reaction chamber 35A and the reactant supply device 31 are connected to each other. The communication is made through the supply opening 36A. At this time, the opening of the one reaction chamber 35A and the other reaction chamber 35A on the opposite side in the radial direction coincides with the shock wave introduction opening 36B opposed to the supply opening 36A in the radial direction. Thereafter, when the rotating body 35 is rotated four times by 45 °, that is, by 180 °, the shock wave introduction opening 36B and the one reaction chamber 35A coincide with each other, and the power generation of the one reaction chamber 35A and the power generation apparatus 20 is achieved. The flow path 21 communicates with the shock wave introduction opening 36B. When the opening of the one reaction chamber 35A does not coincide with the supply opening 36A and the shock wave introduction opening 36B during the 180 ° rotation and faces the lid surface (wall surface) of the opening / closing member 36, the lid surface causes The left end opening of one reaction chamber 35A is closed. As a result, the communication between the one reaction chamber 35A and the reactant supply device 31 and the power generation channel 21 is substantially blocked.

Further, as described above, when the left end opening of the one reaction chamber 35A coincides with the shock wave introduction opening 36B, the one reaction chamber 35A coincides with the discharge port 37A on the discharge side, via the control valve 37B shown in FIG. Thus, communication with the buffer tank 32 is possible. When the one reaction chamber 35A faces the lid surface of the opening / closing member 37 without being aligned with the discharge port 37A, the right end opening of the reaction chamber 35A is substantially closed by the lid surface.

  Thus, as can be seen from FIG. 4, the plurality of reaction chambers 35 </ b> A coincide with the supply opening 36 </ b> A on the supply side and face the lid surface of the opening / closing member 37 on the discharge side by intermittent rotation of the rotating body 35. One reaction chamber 35A receives the supply of reactants sequentially and intermittently. Then, when the opening of the reaction chamber 35A that has been supplied with the reactant comes to a position that coincides with the shock wave introduction opening 36B after the rotation of the rotator 35 by 180 °, the control valve 37B in FIG. 1 remains closed. The shock wave of the combustion gas from the detonation generator 10 propagates into the reaction chamber 35A through the power generation channel 21. The reaction material is shock-compressed in the reaction chamber 35A by the shock wave and becomes a high temperature, and carbon dioxide in the reaction material undergoes a thermal decomposition reaction to generate a carbon-containing gas. Thereafter, the control valve 37B is opened, and the carbon-containing gas is discharged from the reaction chamber 35A through the discharge port 37A of the opening / closing member 37 and stored in the buffer tank 32. In the present embodiment, the reaction apparatus 30 is configured as described above, but the form is not particularly limited. For example, the reactor may not be rotating as described above but may be non-rotating. In such a configuration, the number and shape of the reaction chambers are arbitrary, and the reaction chamber may have a reaction chamber suitable for instantaneously compressing the reactants upon receiving the shock wave of the combustion gas from the detonation generator 10. Good.

  The buffer tank 32 is formed to have a relatively large capacity, and the pressure of the high-pressure carbon-containing gas from the reaction chamber 35A is rapidly relaxed, and the carbon-containing gas is rapidly cooled by the pressure relaxation to sublimate the carbon. The carbon in the carbon-containing gas is solidified at a temperature below the point (3370 ° C.) and dropped to be taken out. When a hydrocarbon or carbon-containing substance is supplied as a reactant from the reactant supply device 31 to the reaction chamber 35A, as shown by a broken line in FIG. It is possible to provide a return path 50 that allows the gas to be returned to the above-described fuel supply device 11 as fuel and used effectively. In addition, a hydrogen separator (for example, PSA) 51 that separates hydrogen from a hydrogen-containing gas whose pressure fluctuation has been reduced in the buffer tank 32 can be connected to the buffer tank 32. The hydrogen separated by the hydrogen separator 51 can be used for each suitable application. The hydrogen separation device 51 returns the residual gas (mainly carbon monoxide) after separating hydrogen from the hydrogen-containing gas to the fuel supply device 11 as a fuel for effective use. It is also possible to connect.

  Next, the operation of the apparatus according to the present embodiment will be described with reference to FIGS.

  1) In the detonator 10, first, fuel and preheated air in the ignition chamber 13, the dispersion chamber 15, the induction path 16, and the combustion chamber 14, almost at a theoretical mixing ratio or under an air shortage condition than the theoretical mixing ratio. Is filled from the ignition chamber 13. At the time of filling, a closed circuit formed by the coil 23 as the first conductive member, the second conductive member 24, the DC power source 26, the capacitor 27, the inverter 28, and the load 29 shown in FIG. Thus, an initial current is generated in advance, and a magnetic field is formed in the power generation channel 21. In addition, one reaction chamber 35A of the reaction device 30 has already been supplied with reactants, and the combustion chamber 14 communicates with the one reaction chamber 35A via the power generation device 20.

  2) Next, when the spark plug 13A is operated, detonation occurs due to ignition in the ignition chamber 13, and the detonation wave propagates to the introduction side end portion 14A of the combustion chamber 14 through the dispersion chamber 15 and the guide path 16. Is done. At that time, the plurality of guide paths 16 are set to be equal to each other, so detonation waves of the plurality of guide paths 16 reach the introduction side end portion 14 </ b> A of the combustion chamber 14 at the same time.

In the combustion chamber 14, a plurality of detonation waves travel from the inlet side end portion 14A to the outlet opening end portion 14B. However, since the cross-sectional area of the combustion chamber 14 gradually decreases toward the downstream, the detonation wave converges. As the temperature propagates downstream, the temperature and pressure increase.

  A power generation device 20 is connected to the outlet opening end portion 14B of the combustion chamber 14, and the combustion gas dissociated or ionized by detonation flows into the power generation passage 21 of the power generation device 20 as a conductive fluid.

  Further, the mixing ratio of the fuel and the preheated air is not necessarily the theoretical mixing ratio. By changing the mixing ratio, the flame peak generation timing changes, so that the detonation generation position in the flame traveling direction in the combustion chamber 14 can be the introduction side end portion 14A of the combustion chamber 14, thereby The ultimate temperature and pressure of the detonation wave in the combustion chamber 14 are maximized.

As fuel, pure fuel such as methane, methanol, kerosene, heavy oil, etc., low quality fuel such as coal tar, crude oil, waste plastic, digested gas of sewage treatment sludge, and by-product gas at steelworks are used. be able to. The main components of the combustion gas generated by the combustion reaction of these fuels with preheated air are CO ₂ and H ₂ O. The combustion gas starts dissociation at about 1500 K by detonation and starts ionization at about 3000 K. Then, it is sent to the power generation channel as a conductive fluid.

  3) When the dissociated or ionized combustion gas flows into the power generation flow path 21 with a shock wave, the combustion gas travels from the upstream to the downstream along the power generation flow path 21 while the coil 23 and the second The conductive member 24 is short-circuited from the upstream end side. That is, the short circuit range between the coil 23 and the second conductive member 24 is the upstream end of each of the coil 23 and the second conductive member 24 by the combustion gas sent to the power generation passage 21. It is expanded from the part toward the downstream end. Thus, when the short circuit range is expanded, the coil 23 and the second conductive member 24 form a closed circuit on the downstream side of the short circuit range. The part forming the inductance of the closed circuit including the conductive member 24 is substantially only the downstream part. Since the combustion gas has a high flow rate of 10 km / s or more, the coil 23 and the second conductive material are connected downstream of the short circuit range due to the sudden expansion of the short circuit range. The inductance of the member 24 decreases rapidly. An induced current is generated in the coil 23 so as to form the magnetic field. However, since the inductance of the coil 23 is reduced, the induced current is increased beyond the initial current. Since the magnetic field of the coil 23 increases due to the increase of the induced current, the induced current further increases. The induced current thus increased is obtained as a pulse current at the downstream end. This pulse current is converted into AC power by the capacitor 27 and the inverter 28 and supplied to the load 29.

  After obtaining AC power as described above, the control valve 18A of the combustion chamber 14 shown in FIG. 1 is changed from the closed state to the open state, and the combustion exhaust gas in the combustion chamber 14 is transferred from the exhaust port 18 to the gas turbine 40. Electric power is also obtained in the gas turbine 40 by utilizing the high energy supplied and remaining in the combustion gas.

  4) The shock wave of the combustion gas after passing through the power generation flow channel 21 reaches the reaction chamber 35A for the purpose of effectively using the carbon-containing gas. When the shock wave of the combustion gas is propagated from the shock wave introduction opening 36B of the opening / closing member 36 into the reaction chamber 35A that has already been supplied with the reactant, the reactant in the reaction chamber 35A reacts by the shock wave. Impact compression is performed toward the discharge side end (the right end in FIG. 4) of the chamber 35 </ b> A and the temperature becomes high, for example, 6000K. Under this high temperature condition, the carbon dioxide in the reactant reacts thermally, and as a result, a carbon-containing gas is obtained.

  Such a reaction is successively performed in each reaction chamber 35A communicated with the shock wave introduction opening 36B by intermittent rotation of the rotating body 35, and a carbon-containing gas is generated each time.

  5) Next, the carbon-containing gas produced in the reaction chamber 35A is ejected into the buffer tank 32 by the opening of the control valve 37B and temporarily stored. At this time, since the high-temperature carbon-containing gas jetted into the buffer tank 32 is rapidly cooled under heat insulation, the reverse reaction is prevented and the carbon is cooled below its sublimation point. The carbon in the gas can be separated and removed as a solid. Further, the buffer tank 32 has a large capacity, and once the high-pressure carbon-containing gas injected into the buffer tank 32 is once stored, the pressure fluctuation of the carbon-containing gas is alleviated and a stable low pressure is achieved. Become. As described above, in the present embodiment, the reverse reaction is prevented by lowering the pressure and temperature of the carbon-containing gas, which was high temperature and high pressure at the time of generation, in the buffer tank 32, and the reactant is supplied in the reaction chamber 35A. The ratio of the amount of carbon-containing gas produced to the amount is increased.

  When the reactant supply device 31 supplies the reaction chamber 35A to the reaction chamber 35A by using a substance containing hydrocarbon or carbon as a reactant, a buffer 50 is provided by a return path 50 indicated by a broken line in FIG. The hydrogen-containing gas in the tank 32 is returned to the ignition chamber 13 as fuel and used effectively.

  In this embodiment, the combustion chamber, the power generation channel for power generation, and the reaction chamber communicate in series in this order, but the combustion chamber, the reaction chamber, and the power generation channel may be in this order. The power generation channel and the reaction chamber may be communicated in parallel with the combustion chamber.

  In this embodiment, one detonation generator communicates with a reaction apparatus having a plurality of reaction chambers via a power generation device. There may be one chamber instead of a plurality of chambers. In this case, a plurality of detonations are generated by connecting a plurality of detonators to a reactor having one reaction chamber in parallel via a power generator. It is possible to generate detonation sequentially in the apparatus and to send the combustion gas as a conductive fluid to the power generation apparatus almost continuously to propagate the shock wave of the combustion gas to the one reaction chamber.

  In the present embodiment, the second conductive member 24 is arranged on the axis 22 of the power generation flow path 21. However, the second conductive member has an overlapping range with respect to the coil in the flow direction, and has a gap in the power generation flow path. If it is arranged, it can be arranged at any position. For example, like the 2nd electroconductive member 24B shown in FIG. 5, you may distribute | arrange on the surrounding wall of the electric power generation flow path 21 along the envelope surface of the coil 23. FIG.

  The second conductive member 24 </ b> B is attached to the insulating material 25 together with the coil 23, and is arranged in a non-contact manner with respect to the coil 23. Further, the second conductive member 24B is arranged in a part of the circumferential direction as shown in FIG. 5B, and extends along the outer circumference of the coil 23 in the axial direction as shown in FIG. 5A. In the radial direction, the coil extends between the conductors of the coil 23 to the same radial position as the inner periphery of the coil 23 to form a comb shape. The coil 23 and the second conductive member 24B are short-circuited in the flow direction by the combustion gas dissociated or ionized in the power generation passage 21, and the induced current is similar to the embodiment shown in FIG. Is taken out.

  In addition, the second conductive member is coiled, and the coil and the second conductive member are alternately positioned between the conductive wires of the coil 23 serving as the first conductive member. The conductive member may be arranged in a double coil shape. Thereby, the induced current generated in the coil 23 can be continuously increased, and the power generation efficiency can be improved.

In addition, instead of the above-mentioned reactants, a hazardous substance containing any one of chlorofluorocarbon, polychlorinated biphenyls, and dioxins is supplied to the reaction chamber, and heated at high temperature by impact compression by a combustion gas shock wave. It is possible to make the harmful substance harmless by causing a decomposition reaction of the harmful substance. Further, for example, medical waste may be supplied as a harmful substance to the reaction chamber.
