  An embodiment of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, a power generation system 10 according to the present invention includes a dust supply means 22 for introducing dust, a plurality of pressurizing chambers 13, a combustion cylinder 12 that causes a dust explosion within a predetermined pressure, and a dust explosion caused by ignition. , The wind body 11 that receives the blast of the dust explosion and converts it into rotational energy, and the power generator 14 that generates the wind body 11 with rotational force.

  The dust supply means 22 is a device that inputs plant dust. The plant dust is, for example, a fine powder of plants such as wheat straw, rice straw, and weeds, which are singly or mixed. Plant dust is used because it is difficult to generate toxic gases. In addition, CO2 is generated during dust explosion, but the plant absorbs carbon neutral.

  The finer the particle size of the dust, the closer to the gas at the time of the explosion, and it can be easily exploded by igniting a mixture of dust and air. By adjusting the amount of dust and air mixed, the magnitude of the explosion can be changed. In addition, by mixing dusts having different particle diameters, it is possible to prevent the particles from becoming one lump when the dust is charged, and to improve the explosiveness.

  Further, the power generation system 10 according to the present invention is provided with a compressor 21 for sending pressurized air separately from the dust supply means 22. The compressor 21 functions as compressed air supply means for supplying compressed air to the combustion cylinder 12. The air pressurized by the compressor 21 is introduced into the combustion chamber 12 at the same time as dust is introduced into the combustion cylinder 12.

  As shown in FIG. 2, the pressurizing chamber 13 has a plurality of sealed chambers, and the pressurizing chambers 13a and 13b are pressurized with a predetermined pressure. The pressure in each of the pressurizing chambers 13a and 13b increases as the chamber is closer to the combustion cylinder 12. An on-off valve 32 that opens only in one direction is disposed between the pressurizing chambers 13a and 13b. In this embodiment, the pressurizing chambers 13a and 13b, the compressor 21, and the dust supply means 22 are provided for each combustion cylinder 12.

  The ignition means 17 generates a spark in a predetermined time. The spark is generated by, for example, a spark plug. The timing for ignition is controlled by a control program.

  The combustion cylinder 12 is for causing a dust explosion in a container pressurized to a predetermined pressure. The combustion cylinder 12 is hollow and formed in a bell shape, for example. The combustion cylinder 12 has sufficient strength so that it will not be destroyed or damaged even during a dust explosion.

  The wind vehicle body 11 receives rotational blast from dust explosion in the combustion cylinder 12 and generates rotational energy. The wind vehicle body 11 is mainly composed of blades that receive an explosion and a rotating shaft, and is disposed at the upper end portion of the combustion cylinder 12.

  The power generation device 14 is connected to the turbine rotating shaft 19 of the wind body 11 and generates electric power by receiving rotational energy of the rotating shaft of the wind body 11. In addition, you may make it connect with the electric power generating apparatus 14 via the speed increasing means 25 from the turbine rotating shaft 19 of the wind vehicle body 11. FIG.

  The combustion cylinder 12 is provided with an exhaust duct 18 for exhausting the explosive combustion. The exhaust duct 18 is formed in a cylindrical shape, and exhausts exhaust gas after explosion.

  Further, an afterburner 16 is disposed in the middle of the exhaust duct 18. The afterburner 16 is for completely burning the incomplete combustion during the dust explosion. Thus, the afterburner 16 is disposed in the combustion cylinder 12 and burns incomplete combustion components due to dust explosion generated in the combustion cylinder 12.

  Further, a heat pipe 20 is disposed along the inner wall of the exhaust duct 18. The heat pipe 20 is arranged so as to circulate in the combustion cylinder 12, and receives water generated as a result of combustion of incomplete combustion components by the afterburner 16 to supply water that becomes hot water. The heat pipe 20 is formed of a material having thermal conductivity. One end of the heat pipe 20 extends into the water tank 28, and the other end extends to the steam / water separator 15. The steam separator 15 separates the hot water supplied from the heat pipe 20 into steam and water. A pump 26 for pumping water from the water tank 28 is disposed on the heat pipe 20.

  Further, the rotational energy of the wind body 11 is input to the steam / water separator 15 and separated into water and steam by the steam / water separator 15, and the separated steam is used to drive the steam turbine 27. The water tank 28 can also be supplied.

  The steam turbine 27 is driven by the steam generated by the steam separator 15. The steam turbine 27 has a smaller driving capability than the main wind vehicle body 11, but the power generation amount can be increased by arranging a plurality of steam turbines 27. The turbine shaft portion 19 a of the steam turbine 27 may be coaxial with the turbine rotating shaft 19 of the wind body 11 or may be a separate turbine shaft.

  The power generation system 10 configured as described above generates power by the following method. First, dust is prepared and supplied to the dust supply means 22. Next, the pressurized chamber 13 is filled with compressed air by the compressor 21.

  After supplying dust and pressurized air to the first pressurizing chamber 13a, the first on-off valve 32 is opened, and these are supplied to the second pressurizing chamber 13b. Next, after opening the second on-off valve 33, dust and pressurized air are supplied into the combustion cylinder 12. Thereafter, the third on-off valve 34 and the second on-off valve 33 are closed.

  Then, dust explosion is caused in the combustion cylinder 12. That is, sparks are generated by the ignition means 17 and the mixture of dust and pressurized air is ignited to cause a dust explosion while generating a flame in the combustion cylinder 12.

  Since the predetermined set pressure is exceeded at the time of explosion, only the third on-off valve is openable. After opening the third on-off valve, the inside of the combustion cylinder 12 becomes negative pressure. Thereafter, the third on-off valve is closed, and dust that causes the next explosion is introduced from the dust supply means 22 by opening the first on-off valve 32 and the second on-off valve 33.

  Thus, a blast can be generated by the explosion, and the rotating shaft of the wind vehicle body 11 is driven by the blast. In addition, by driving the rotating shaft of the wind body 11, the power generator 14 generates power using the rotational energy of the rotating shaft of the wind body 11.

  Moreover, although the wind vehicle body 11 is rotated by dust explosion, it is difficult to drive the rotating shaft of the wind vehicle body 11 at the time of starting. If an attempt is made to rotate the rotating shaft of the wind vehicle body 11 by the blast of the dust explosion, the main body of the wind vehicle body 11 and the turbine rotating shaft 19 may be damaged. Therefore, during the initial operation, the starter motor 23 can be driven to rotate the flywheel 24 and the drive shaft of the wind body 11 can be rotated.

  FIG. 4 is a graph showing the relationship between time and turbine speed. Until T1, the rotation speed of the wind vehicle body 11 by the starter motor is increased, and from T2, the rotation speed of the wind vehicle body 11 is increased by dust explosion.

  The explosion may be performed separately for each combustion cylinder 12, and can be performed in the order of the first cylinder → the third cylinder → the fourth cylinder → the second cylinder, for example. As described above, in the power generation system 10 of the present embodiment, the first explosion control is performed in which dust explosions caused by all the four combustion cylinders 12 are continuously generated in a predetermined order. By performing such first explosion control, it is possible to perform continuous operation by equalizing the load on the rotating shaft of the turbine generated during the explosion.

  Further, in the power generation system 10, in the configuration including the plurality of combustion cylinders 12, as explosion control, second explosion that continuously generates dust explosions in only a part of the plurality of combustion cylinders 12 in a predetermined order. You can also control the explosion. For example, during the daytime when the demand for electric power increases, power is generated by generating a dust explosion in all of the first to fourth cylinders. On the other hand, in the time zone when the electricity demand at night is low, only the combustion cylinders, for example, only the first cylinder and the fourth cylinder (or the second cylinder and the first cylinder) at the line symmetrical position with respect to the central portion of the four combustion cylinders It is possible to adjust the power generation amount by continuously performing dust explosion for only three cylinders) and stopping only the other second and third cylinders (or only the first and fourth cylinders).

  Further, in the power generation system 10 of the present embodiment, the stop of the dust explosion in the combustion cylinder 12 that does not perform the dust explosion among the plurality of combustion cylinders 12 in the second explosion control is applied to the combustion cylinder 12 by the dust supply means 22. This is done by stopping the supply of dust. Thereby, the dust explosion in the combustion cylinder 12 can be easily stopped. However, the method of stopping the dust explosion in the combustion cylinder 12 is not limited to stopping the supply of dust, and may be performed, for example, by stopping the compressed air to the combustion chamber 12 or stopping the ignition by the ignition means 17. . Thus, in the power generation system 10, the first explosion control and the second explosion control as described above are selectively performed. Such explosion control is performed by a control unit included in the power generation system 10.

  It is difficult to supply the necessary amount of power when necessary in the existing nuclear power generation method, thermal power generation method, and hydroelectric power generation method. In contrast, the power generation system according to the present embodiment can solve this problem.

  Next, the power generation system 10 that converts water into warm water and drives the steam turbine 27 will be described. As shown in FIG. 3, the heat pipe 20 converts the water pumped from the pump 26 by the heat burned by the afterburner 16 into hot water and supplies the hot water to the steam separator 15. That is, the water in the water tank 28 is pumped by the pump 26, and the pumped water is put into the heat pipe 20.

  Then, the incomplete combustion due to the explosion in the combustion cylinder 12 is burned by the afterburner 16, and the burned heat is transferred to the steam separator 15 using the water flowing through the heat pipe 20 as warm water. The steam is separated into water and steam by the steam separator 15.

  By supplying the separated steam to the steam turbine 27, the steam turbine 27 can be driven, and the power generation apparatus 14 can generate electric power using the driving energy. In the steam turbine 27, a catalyst having a low boiling point can be used to make it easier to generate steam.

  Furthermore, the water separated separately from the steam can be circulated as water for supplying the new heat pipe 20 by returning the water to the pump 26.

  In this embodiment, water is circulated outside the combustion cylinder 12. For example, the combustion cylinder 12 is immersed in the water tank 35 so that water is circulated through the water tank 35. The combustion cylinder 12 is made of a material having thermal conductivity. With this configuration, heat can be generated from the combustion cylinder 12, and water can be heated outside the combustion cylinder 12.

  Further, the water in the water tank 35 can be supplied to the water tank 28 for the heat pipe 20. This is because when the water to be circulated through the heat pipe 20 is warm water or when the warm water is partially steamed, the amount of water returned to the water tank 28 decreases, so that the decrease can be supplied from the water tank 35. I am doing so.

  According to the power generation system 10 in the present embodiment, hot water obtained by heat generated by dust explosion generated in the combustion cylinder 12 is supplied to the greenhouse 36, and greenhouse cultivation is possible in the greenhouse 36. In this way, the energy of the dust explosion can be used as a substitute for the greenhouse-grown fuel in the greenhouse 36.

  Furthermore, as shown in FIG. 5, the cylindrical body 44 is formed to be elongated toward the upper end thereof, and the upper end and the lower end are opened. Further, the rectifying plate 30 is disposed on the inner wall portion on the upper end side of the cylindrical body 44. In the rectifying plate 30, a space is formed in the central portion thereof, and a plate material is spirally disposed on the inner peripheral wall surface of the cylindrical body 44. A power generator 14 is driven by disposing a blade 31 (propeller) for wind power generation above the rectifying plate 30 so as to be rotatable about a vertical axis.

  Thus, the updraft can be generated in a spiral shape through the rectifying plate 30 by the heat of the heat pipe 20 disposed in the cylinder 44 while taking in the atmosphere from the opening at the lower end of the cylinder 44. The blade 31 for wind power generation provided on the upper end side of the cylindrical body 44 can be rotated to generate power. Further, the updraft can be generated throughout the year regardless of the weather, so that stable power generation with a constant output can be achieved.

  FIG. 6 shows another power generation configuration of the power generation system 10 of the present invention. That is, as shown in FIG. 6, a large hole having a predetermined depth from the ground is formed, concrete is placed on the inner wall portion of the hole, and a large arrangement hole 40 having an open upper portion is installed. Four combustion cylinders 12 are arranged in the hole 40 with a predetermined interval.

  Further, a seismic isolation laminated rubber 41 that is a seismic isolation member is disposed between the combustion cylinder 12 and the bottom surface of the arrangement hole 40. Further, seismic isolation dampers 42 as seismic isolation members are disposed between the combustion cylinders 12 or between the wall surfaces of the arrangement holes 40 and the combustion cylinders 12 on both ends. Thus, since the seismic isolation laminated rubber 41 and the seismic isolation damper 42 are provided, the vibration and impact at the time of an explosion can be reduced and it can be set as the seismic isolation structure with respect to an earthquake.

  Further, a water tank 43 is provided around the combustion cylinder 12, the inside of the water tank 43 is filled with water, a lid is provided, and the water tank 43 is filled with pressurized cooling water by adjusting with the pressurizing valve 46. . With this pressurized cooling water, the inside of the combustion cylinder 12 can be cooled, and explosion sound, impact and vibration during an earthquake or explosion can be absorbed.

  FIG. 7 is an explanatory diagram showing the overall structure of the power generation system 10 in the present embodiment. As shown in FIG. 7, the present embodiment includes three power generation devices 14. That is, the first power generation device 14 that directly uses the dust explosion, the second power generation device 14 that uses the steam separator 15, and the ascending air current that is generated in the cylindrical body 44. A third power generation device 14 is used.

  In addition, as shown in FIG. 7, the water tank 43 in which the combustion cylinder 12 is disposed is filled with pressurized cooling water. And when water becomes high temperature and cooling water expand | swells and the water in the water tank 43 becomes more than predetermined pressure, it opens in the greenhouse 36 etc. by open valves (not shown) like a pressure valve of a radiator. You may make it escape hot water.

  Further, as shown in FIG. 7, water may be cooled through finned pipes 47 in the greenhouse 36, and the cooling water may be returned to the water tank 43 in which the combustion cylinder is disposed. The hot water supplied through the heat pipe 20 may also cool the water through the finned pipe 47 or the heat storage layer in the cylindrical body 44 and return the cooling water to the water tank 43. In the present embodiment, the finned pipe 47 arranged in the greenhouse 36 and the cylinder 44 receives the heat generated by the dust explosion generated in the combustion cylinder 12 and circulates the water that becomes hot water. Function as.

  In other words, the cylindrical body 44 is a member that houses a part of the finned pipe 47 as a hot water circulation pipe, has an upper end and a lower end, and is tapered toward the upper side. Further, the rectifying plate 30 is disposed along the inner peripheral surface of the cylindrical body 44 above the finned pipe 47 in the cylindrical body 44, and has a spiral shape with the cylindrical axis direction of the cylindrical body 44 being the central axis direction. It is a plate-like member. Further, the blade 31 is provided in the cylindrical body 44, and rotates in the cylindrical body 44 by the upward swirling airflow generated by the finned pipe 47 and the rectifying plate 31. The power generation system 10 includes a power generation device 14 that generates power by rotating the blade 31.

  As a result, the power generation system 10 can generate power using the energy of the explosion by utilizing the dust explosion that is likely to cause an explosion. Moreover, the dust which produces an explosion can be obtained easily, and a fossil fuel etc. are not required at the time of an explosion.

  An embodiment of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, a power generation system 10 according to the present invention includes a dust supply means 22 for introducing dust, a plurality of pressurizing chambers 13, a combustion cylinder 12 that causes a dust explosion within a predetermined pressure, and a dust explosion caused by ignition. , The wind body 11 that receives the blast of the dust explosion and converts it into rotational energy, and the power generator 14 that generates the wind body 11 with rotational force.

  The dust supply means 22 is a device that inputs plant dust. The plant dust is, for example, a fine powder of plants such as wheat straw, rice straw, and weeds, which are singly or mixed. Plant dust is used because it is difficult to generate toxic gases. In addition, CO2 is generated during dust explosion, but the plant absorbs carbon neutral.

  The finer the particle size of the dust, the closer to the gas at the time of explosion, and it can be easily exploded by igniting a mixture of dust and air. By adjusting the amount of dust and air mixed, the magnitude of the explosion can be changed. In addition, by mixing dusts having different particle diameters, it is possible to prevent the particles from becoming one lump when the dust is charged, and to improve the explosiveness.

  Further, the power generation system 10 according to the present invention is provided with a compressor 21 for sending pressurized air separately from the dust supply means 22. The compressor 21 functions as compressed air supply means for supplying compressed air to the combustion cylinder 12. The air pressurized by the compressor 21 is introduced into the combustion chamber 12 at the same time as dust is introduced into the combustion cylinder 12.

As shown in FIG. 2, the pressurizing chamber 13 has a plurality of sealed chambers (pressurizing chambers 13a and 13b) , and the pressurizing chambers 13a and 13b are pressurized with a predetermined pressure. The pressure in each pressure chamber 13a, 13b is enhanced near Iho throat pressure in the combustion liner 12. An on-off valve 32 that opens only in one direction is disposed between the pressurizing chambers 13a and 13b. In this embodiment, the pressurizing chambers 13a and 13b, the compressor 21, and the dust supply means 22 are provided for each combustion cylinder 12.

  The ignition means 17 generates a spark in a predetermined time. The spark is generated by, for example, a spark plug. The timing for ignition is controlled by a control program.

  The combustion cylinder 12 is for causing a dust explosion in a container pressurized to a predetermined pressure. The combustion cylinder 12 is hollow and formed in a bell shape, for example. The combustion cylinder 12 has sufficient strength so that it will not be destroyed or damaged even during a dust explosion.

  The wind vehicle body 11 receives rotational blast from dust explosion in the combustion cylinder 12 and generates rotational energy. The wind vehicle body 11 is mainly composed of blades that receive an explosion and a rotating shaft, and is disposed at the upper end portion of the combustion cylinder 12.

  The power generation device 14 is connected to the turbine rotating shaft 19 of the wind body 11 and generates electric power by receiving rotational energy of the rotating shaft of the wind body 11. In addition, you may make it connect with the electric power generating apparatus 14 via the speed increasing means 25 from the turbine rotating shaft 19 of the wind vehicle body 11. FIG.

  The combustion cylinder 12 is provided with an exhaust duct 18 for exhausting the explosive combustion. The exhaust duct 18 is formed in a cylindrical shape, and exhausts exhaust gas after explosion.

  Further, an afterburner 16 is disposed in the middle of the exhaust duct 18. The afterburner 16 is for completely burning the incomplete combustion during the dust explosion. Thus, the afterburner 16 is disposed in the combustion cylinder 12 and burns incomplete combustion components due to dust explosion generated in the combustion cylinder 12.

Further, a hot water circulation pipe 20 is disposed along the inner wall of the exhaust duct 18. The hot water circulation pipe 20 is arranged so as to circulate in the combustion cylinder 12, and receives the heat generated by the combustion of the incomplete combustion component by the afterburner 16, and feeds water that becomes hot water. The hot water circulation pipe 20 is formed of a material having thermal conductivity. One end of the hot water circulation pipe 20 extends to the inside of the water tank 28, and the other end extends to the steam / water separator 15. The steam separator 15 separates the hot water supplied from the hot water circulation pipe 20 into steam and water. A pump 26 for pumping water from the water tank 28 is disposed on the hot water circulation pipe 20 .

  Further, the rotational energy of the wind body 11 is input to the steam / water separator 15 and separated into water and steam by the steam / water separator 15, and the separated steam is used to drive the steam turbine 27. The water tank 28 can also be supplied.

  The steam turbine 27 is driven by the steam generated by the steam separator 15. The steam turbine 27 has a smaller driving capability than the main wind vehicle body 11, but the power generation amount can be increased by arranging a plurality of steam turbines 27. The turbine shaft portion 19 a of the steam turbine 27 may be coaxial with the turbine rotating shaft 19 of the wind body 11 or may be a separate turbine shaft.

  The power generation system 10 configured as described above generates power by the following method. First, dust is prepared and supplied to the dust supply means 22. Next, the pressurized chamber 13 is filled with compressed air by the compressor 21.

  After supplying dust and pressurized air to the first pressurizing chamber 13a, the first on-off valve 32 is opened, and these are supplied to the second pressurizing chamber 13b. Next, after opening the second on-off valve 33, dust and pressurized air are supplied into the combustion cylinder 12. Thereafter, the third on-off valve 34 and the second on-off valve 33 are closed.

  Then, dust explosion is caused in the combustion cylinder 12. That is, sparks are generated by the ignition means 17 and the mixture of dust and pressurized air is ignited to cause a dust explosion while generating a flame in the combustion cylinder 12.

Only the third on-off valve exceeds a set pressure is freely opened during the explosion. After opening the third on-off valve, the inside of the combustion cylinder 12 becomes negative pressure. Thereafter, the third on-off valve is closed, and dust that causes the next explosion is introduced from the dust supply means 22 by opening the first on-off valve 32 and the second on-off valve 33.

  Thus, a blast can be generated by the explosion, and the rotating shaft of the wind vehicle body 11 is driven by the blast. In addition, by driving the rotating shaft of the wind body 11, the power generator 14 generates power using the rotational energy of the rotating shaft of the wind body 11.

  Moreover, although the wind vehicle body 11 is rotated by dust explosion, it is difficult to drive the rotating shaft of the wind vehicle body 11 at the time of starting. If an attempt is made to rotate the rotating shaft of the wind vehicle body 11 by the blast of the dust explosion, the main body of the wind vehicle body 11 and the turbine rotating shaft 19 may be damaged. Therefore, during the initial operation, the starter motor 23 can be driven to rotate the flywheel 24 and the drive shaft of the wind body 11 can be rotated.

  FIG. 4 is a graph showing the relationship between time and turbine speed. Until T1, the rotation speed of the wind vehicle body 11 by the starter motor is increased, and from T2, the rotation speed of the wind vehicle body 11 is increased by dust explosion.

The explosion may be performed separately for each combustion cylinder 12, and can be performed in the order of the first cylinder → the third cylinder → the fourth cylinder → the second cylinder, for example. Thus, in the power generation system 10 of the present embodiment, the first explosion control causing a continuous manner a dust explosion due to the four combustion liner 12 all is performed. By performing such first explosion control, it is possible to perform continuous operation by equalizing the load on the rotating shaft of the turbine generated during the explosion.

Further, in the power generation system 10, in a configuration comprising a plurality of combustion liner 12, blast control as a plurality of second explosion causing a continuous manner a dust explosion due to only a portion of the combustion liner 12 of the combustion barrel 12 Control can also be performed. For example, during the daytime when the demand for electric power increases, power is generated by generating a dust explosion in all of the first to fourth cylinders. On the other hand, in the time zone when the electricity demand at night is low, only the combustion cylinders, for example, only the first cylinder and the fourth cylinder (or the second cylinder and the first cylinder) at the line symmetrical position with respect to the central portion of the four combustion cylinders It is possible to adjust the power generation amount by continuously performing dust explosion for only three cylinders) and stopping only the other second and third cylinders (or only the first and fourth cylinders).

  Further, in the power generation system 10 of the present embodiment, the stop of the dust explosion in the combustion cylinder 12 that does not perform the dust explosion among the plurality of combustion cylinders 12 in the second explosion control is applied to the combustion cylinder 12 by the dust supply means 22. This is done by stopping the supply of dust. Thereby, the dust explosion in the combustion cylinder 12 can be easily stopped. However, the method of stopping the dust explosion in the combustion cylinder 12 is not limited to stopping the supply of dust, and may be performed, for example, by stopping the compressed air to the combustion chamber 12 or stopping the ignition by the ignition means 17. . Thus, in the power generation system 10, the first explosion control and the second explosion control as described above are selectively performed. Such explosion control is performed by a control unit included in the power generation system 10.

  It is difficult to supply the necessary amount of power when necessary in the existing nuclear power generation method, thermal power generation method, and hydroelectric power generation method. In contrast, the power generation system according to the present embodiment can solve this problem.

Next, the power generation system 10 that converts water into warm water and drives the steam turbine 27 will be described. As shown in FIG. 3, the hot water circulation pipe 20 converts the water pumped up from the pump 26 by the heat burned by the afterburner 16 into hot water and supplies the hot water to the steam separator 15. That is, the water in the water tank 28 is pumped up by the pump 26, and the pumped water is put into the hot water circulation pipe 20 .

Then, the incomplete combustion due to the explosion in the combustion cylinder 12 is combusted by the afterburner 16, and the heat flowing through the hot water circulation pipe 20 is transferred as hot water to the steam separator 15. Is separated into water and steam by the steam separator 15.

  By supplying the separated steam to the steam turbine 27, the steam turbine 27 can be driven, and the power generation apparatus 14 can generate electric power using the driving energy. In the steam turbine 27, a catalyst having a low boiling point can be used to make it easier to generate steam.

  Furthermore, the water separated separately from the steam can be circulated as water for supplying the new heat pipe 20 by returning the water to the pump 26.

  In this embodiment, water is circulated outside the combustion cylinder 12. For example, the combustion cylinder 12 is immersed in the water tank 35 so that water is circulated through the water tank 35. The combustion cylinder 12 is made of a material having thermal conductivity. With this configuration, heat can be generated from the combustion cylinder 12, and water can be heated outside the combustion cylinder 12.

Furthermore, the water in the water tank 35 can be supplied to the water tank 28 for the hot water circulation pipe 20 . This is because when the water circulated through the hot water circulation pipe 20 is heated, or when the hot water is partially steamed, the amount of water returned to the water tank 28 decreases, and the reduced amount is supplied from the water tank 35. I can do it.

  According to the power generation system 10 in the present embodiment, hot water obtained by heat generated by dust explosion generated in the combustion cylinder 12 is supplied to the greenhouse 36, and greenhouse cultivation is possible in the greenhouse 36. In this way, the energy of the dust explosion can be used as a substitute for the greenhouse-grown fuel in the greenhouse 36.

  Furthermore, as shown in FIG. 5, the cylindrical body 44 is formed to be elongated toward the upper end thereof, and the upper end and the lower end are opened. Further, the rectifying plate 30 is disposed on the inner wall portion on the upper end side of the cylindrical body 44. In the rectifying plate 30, a space is formed in the central portion thereof, and a plate material is spirally disposed on the inner peripheral wall surface of the cylindrical body 44. A power generator 14 is driven by disposing a blade 31 (propeller) for wind power generation above the rectifying plate 30 so as to be rotatable about a vertical axis.

  Thus, the updraft can be generated in a spiral shape through the rectifying plate 30 by the heat of the heat pipe 20 disposed in the cylinder 44 while taking in the atmosphere from the opening at the lower end of the cylinder 44. The blade 31 for wind power generation provided on the upper end side of the cylindrical body 44 can be rotated to generate power. Further, the updraft can be generated throughout the year regardless of the weather, so that stable power generation with a constant output can be achieved.

  FIG. 6 shows another power generation configuration of the power generation system 10 of the present invention. That is, as shown in FIG. 6, a large hole having a predetermined depth from the ground is formed, concrete is placed on the inner wall portion of the hole, and a large arrangement hole 40 having an open upper portion is installed. Four combustion cylinders 12 are arranged in the hole 40 with a predetermined interval.

  Further, a seismic isolation laminated rubber 41 that is a seismic isolation member is disposed between the combustion cylinder 12 and the bottom surface of the arrangement hole 40. Further, seismic isolation dampers 42 as seismic isolation members are disposed between the combustion cylinders 12 or between the wall surfaces of the arrangement holes 40 and the combustion cylinders 12 on both ends. Thus, since the seismic isolation laminated rubber 41 and the seismic isolation damper 42 are provided, the vibration and impact at the time of an explosion can be reduced and it can be set as the seismic isolation structure with respect to an earthquake.

  Further, a water tank 43 is provided around the combustion cylinder 12, the inside of the water tank 43 is filled with water, a lid is provided, and the water tank 43 is filled with pressurized cooling water by adjusting with the pressurizing valve 46. . With this pressurized cooling water, the inside of the combustion cylinder 12 can be cooled, and explosion sound, impact and vibration during an earthquake or explosion can be absorbed.

  FIG. 7 is an explanatory diagram showing the overall structure of the power generation system 10 in the present embodiment. As shown in FIG. 7, the present embodiment includes three power generation devices 14. That is, the first power generation device 14 that directly uses the dust explosion, the second power generation device 14 that uses the steam separator 15, and the ascending air current that is generated in the cylindrical body 44. A third power generation device 14 is used.

  In addition, as shown in FIG. 7, the water tank 43 in which the combustion cylinder 12 is disposed is filled with pressurized cooling water. And when water becomes high temperature and cooling water expand | swells and the water in the water tank 43 becomes more than predetermined pressure, it opens in the greenhouse 36 etc. by open valves (not shown) like a pressure valve of a radiator. You may make it escape hot water.

  Further, as shown in FIG. 7, water may be cooled through finned pipes 47 in the greenhouse 36, and the cooling water may be returned to the water tank 43 in which the combustion cylinder is disposed. The hot water supplied through the heat pipe 20 may also cool the water through the finned pipe 47 or the heat storage layer in the cylindrical body 44 and return the cooling water to the water tank 43. In the present embodiment, the finned pipe 47 arranged in the greenhouse 36 and the cylinder 44 receives the heat generated by the dust explosion generated in the combustion cylinder 12 and circulates the water that becomes hot water. Function as.

  In other words, the cylindrical body 44 is a member that houses a part of the finned pipe 47 as a hot water circulation pipe, has an upper end and a lower end, and is tapered toward the upper side. Further, the rectifying plate 30 is disposed along the inner peripheral surface of the cylindrical body 44 above the finned pipe 47 in the cylindrical body 44, and has a spiral shape with the cylindrical axis direction of the cylindrical body 44 being the central axis direction. It is a plate-like member. Further, the blade 31 is provided in the cylindrical body 44, and rotates in the cylindrical body 44 by the upward swirling airflow generated by the finned pipe 47 and the rectifying plate 31. The power generation system 10 includes a power generation device 14 that generates power by rotating the blade 31.

  As a result, the power generation system 10 can generate power using the energy of the explosion by utilizing the dust explosion that is likely to cause an explosion. Moreover, the dust which produces an explosion can be obtained easily, and a fossil fuel etc. are not required at the time of an explosion.
