Description

  The present invention relates to a thermal steam power generation apparatus that can be installed in a hot spring resort or an area rich in hot water by low cost and simple installation, and that generates power by effectively using hot water and steam.

  Due to the recent rise in the price of fossil fuels (oil and natural gas) and heightened awareness of environmental protection, the spread of power generation devices other than thermal power generation using fossil fuels is required. In particular, the spread of power generation devices using renewable energy is demanded. Examples of power generation using renewable energy include solar power generation, hydroelectric power generation, wind power generation, tidal power generation, ocean current power generation, wave power generation, biomass power generation, and geothermal power generation. All of these generate electric power by turning a turbine using a heat source and a power source existing in the natural environment.

  Unlike fossil fuels, power generation using these renewable energies does not deplete finite resources and, except biomass power generation, does not generate carbon dioxide due to fuel combustion. For this reason, the power generation apparatus using renewable energy has a low environmental load and can cope with the recent increase in environmental protection awareness.

  In addition, nuclear power generation has been widely used as a power generation device that replaces thermal power generation. However, as problems such as accidents and maintenance costs become clear, power generation devices that use renewable energy instead of nuclear power generation are required. ing.

  Under such circumstances, in Japan, wind power generators and solar power generators are being installed and spread by national projects and various projects. Wind power generators are installed in windy mountainous areas or on the ocean, and have been supplying a certain amount of power even though they are small. However, the wind power generator is very large and expensive. In addition, there is a difficulty in transmitting power after power generation, and there is a current situation where entry of wind power generation is limited to companies and power companies with capital.

  With the popularization of photovoltaic power generation panels, photovoltaic power generation has been popularized in both large-scale photovoltaic power generation systems and household photovoltaic power generation. Since the solar power generation device also uses only sunlight, which is a renewable energy, the environmental load is small and there is no concern about resource depletion. However, installation of a large-scale solar power generation system requires a large amount of capital and technology, so there are many bottlenecks in its spread. On the other hand, although solar power generation for home use is easy to spread to individual homes and business establishments, the amount of power generation is small, and there is a problem that it can only meet the power required at home.

  Other tidal power generation and ocean current power generation are still in the experimental stage or prototype stage and require a considerable amount of time and technical solutions to spread.

  As described above, power generation apparatuses using renewable energy such as solar power generation, wind power generation, tidal power generation, and ocean current power generation have problems such as capital power, capital investment, and power generation amount. For this reason, it is required to introduce and disseminate power generation devices that use renewable energy and that are less problematic.

  Japan is a volcanic archipelago and there are many hot springs and hot waters in the country. In addition, unlike foreign hot spring resorts, Japanese hot spring resorts are developed for tourism and hot springs, and are often equipped with transportation infrastructure and housing infrastructure. Naturally, there are a lot of hot water and hot water in the hot spring area, and you can see a lot of steam rising from there. In Japan, there is a problem of wasting these heat sources. Hot water, hot water, and hot water vapor are sufficient heat sources for power generation, and not being used for power generation is a waste of resources.

  For this reason, the proposal of the technique of a geothermal power generation device is made (for example, refer patent document 1 and patent document 2).

JP 2010-7601 A JP 2003-120513 A

  Patent Document 1 discloses a geothermal power generation apparatus that sucks up hot water obtained in a hot spring area, separates it into hot water and steam, and rotates the turbine using the steam to generate power. The hot water is reduced to the ground from which the hot water was obtained using a reduction conduit. Alternatively, hot water is used to heat the separated steam, and the heated steam also rotates the turbine to generate electricity.

  Patent document 2 is a geothermal power generation device called a binary type, and discloses a device that generates a steam by heating a liquid having a low boiling point with hot water and rotating the turbine by the steam. By heating a liquid having a low boiling point, there is an advantage that power generation can be performed using low-temperature steam or hot water that cannot be normally used.

  As disclosed in Patent Documents 1 and 2, the geothermal power generation device in the prior art separates hot water extracted from the ground in a hot spring resort into gas water vapor and liquid hot water, The turbine is used to generate electricity. At this time, the separated liquid is only reduced to the ground and is not effectively utilized. Such a conventional geothermal power generation apparatus only uses hot water obtained in a hot spring area only for power generation, and needs to be installed only for geothermal power generation in a hot spring area. In other words, if it is not installed as a large-scale geothermal power generation device, no merit will be generated due to cost-effectiveness and rights processing problems described later.

  On the other hand, in hot spring areas, there are problems such as the right processing of hot water used for hot springs and development permission, and it is difficult to install a large-scale geothermal power generation device due to the necessity of complicated right processing. This is because it is difficult to adjust interests between the land acquisition and the user who uses it as a hot spring. Alternatively, a hot spring resort with few right holders such as a hot spring inn may be in the mountains and have difficulty in installing a geothermal power generation device. Alternatively, such a hot spring resort with few right holders is located in a national park, and it is often difficult to install a geothermal power generation device due to various regulations.

  Of course, even in hot spring areas where infrastructure such as hot spring inns and tourist facilities are in place, it is naturally possible to use the hot water that springs out to the extent that the unexpected disadvantage of the right holder of the hot spring does not occur .

  Under such circumstances, there has been a demand for a geothermal power generation apparatus that satisfies the following conditions in a hot spring area where infrastructure for tourism and daily life is being developed.

(1) Do not impair the convenience of the right holder of hot springs.
(2) A flexible scale installation according to the installation location is possible without requiring a large-scale construction or a large-scale investment.
(3) The obtained hot water can be used not only for power generation but also for hot spring bathing and other purposes.
(4) Achieving cost-effective power generation.

  An object of this invention is to provide the thermal steam power generator which can implement | achieve sufficient electric power generation, satisfy | filling these conditions (1)-(4) in view of the said subject.

In view of the above-described problems, the thermal steam power generation apparatus of the present invention is a mixed hot water pipe that supplies hot water from a source and is mixed with hot water and steam, and mixed hot water that is rotated by the mixed hot water. A turbine, a steam turbine rotated by steam obtained via the mixed hot water turbine, a rotor that generates electric power by rotating at least one of the mixed hot water turbine and the steam turbine, and at least one of the mixed hot water turbine and the steam turbine A hot water recirculation passage that recirculates at least one of hot water and water vapor passing through as hot water, and is installed between the mixed hot water turbine and the steam turbine and is supplied from the mixed hot water pipeline And a partition for guiding hot water obtained by rotating the mixed hot water turbine to the hot water container. The partition includes the mixed hot water turbine and the steam turbine. And the rotating shaft of the steam turbine passes through the opening and is the same as the rotating shaft of the mixed hot water turbine. The steam turbine and the mixed hot water turbine is that provided adjacent across the opening.

  The thermal steam power generator of the present invention is a mixed hot water turbine that rotates with hot water mixed with hot water and steam without separating hot water obtained from the ground into gas and liquid, and a mixed hot water turbine. By providing the steam turbine rotated by the steam obtained through the above, gas-liquid separation of hot water is not required. Since gas-liquid separation is not required, a flasher and a gas extraction device are not required, and the configuration of the entire power generation device can be simplified. Of course, since the power generation device can be made small, it can be easily installed at a source already used for hot springs.

  Moreover, since it is possible to generate electric power by rotating the turbine without gas-liquid separation, it is not necessary to perform various treatments on the hot water after the use of the turbine rotation. For this reason, hot water can be reduced as it is for hot springs, and there is an advantage that hot water obtained from the hot springs can be used not only for power generation but also for hot springs. For this reason, it can be used for both power generation and hot springs only by installing the thermal steam power generation device of the present invention in the middle of the circulation path of the source spring already used for hot springs. For this reason, the convenience of the hot spring right holder is not impaired.

  In addition, since the hot water used for power generation can be reused as a hot spring without the equipment becoming large, a thermal steam power generator that can flexibly correspond to the scale of the hot spring and the scale of the right holder of the hot spring can be realized. As a result, the spread of geothermal power generation is realized regardless of various regulations and rights processing.

  (Embodiment 1)

(Conventional geothermal power generation)
First, a conventional geothermal power generation device will be described as a reference example. FIG. 1 is a schematic diagram of a geothermal power generation device in the prior art.

  First, a steam well is drilled into a geothermal reservoir such as hot water. When this steam well reaches the geothermal reservoir, it receives the self-injection pressure of the hot water in the geothermal reservoir, and the steam well can take out the hot water. Of course, when the self-injection pressure of the geothermal reservoir is small, the steam well can take out hot water from the geothermal reservoir by applying suction pressure such as a pump.

  The steam well ejects hot water and sends the hot water to the connected two-phase fluid transport pipe. The two-phase fluid transport pipe carries hot water. At this time, the geothermal reservoir contains liquid hot water and gas vapor (including water vapor and steam), and the two-phase fluid transport pipe uses mixed hot water mixed with this liquid and gas. transport. For this reason, it is defined as a two-phase fluid transport pipe by transporting two phases that are a liquid phase and a gas phase.

  The two-phase fluid transport pipe is connected to a steam separator. The steam separator separates the mixed hot water into a liquid and a gas. Steam wells take out extremely high-temperature hot water, which is an underground geothermal reservoir, and the use of this high-temperature hot water in a turbine or the like is problematic in consideration of the durability of the turbine. For this reason, in the conventional geothermal power generation apparatus, the vapor | steam which is gas is used for rotation of a turbine. For this reason, the hot mixed hot water obtained from the geothermal reservoir is separated into liquid and gas. The steam separator separates the vapor obtained by the separation into the primary vapor pipe and delivers the liquid to the flasher.

  The primary steam pipe delivers the steam obtained by the separation to the turbine generator. The steam has an ejection pressure, and the turbine can be rotated by the ejection pressure. Of course, when the jet pressure is weak, it is also preferable to increase the pressure that the steam gives to the turbine by applying pressure to the primary steam pipe.

  The flasher generates steam by expanding hot water, which is a liquid separated by air-water separation, under reduced pressure. This steam is not steam obtained from a steam well, but secondary steam obtained by expanding hot water under reduced pressure. Since hot water is reduced again to the ground, it is not used in the turbine generator. In order to effectively use this hot water, secondary steam is generated by a flasher. The flasher sends the generated secondary steam to the secondary steam pipe.

  The secondary steam pipe, like the primary steam pipe, carries secondary steam to the turbine generator. At this time, the secondary steam also has a predetermined ejection pressure, and the turbine rotates by this ejection pressure. At this time, since the turbine is rotated by the primary steam and the secondary steam, a stronger rotation is generated. Of course, the secondary steam pipe may be applied to increase the pressure when the ejection pressure of the secondary steam is weak.

  The flasher reduces liquid hot water obtained by air-water separation into the ground by a reduction well. This is because hot water itself is very hot and difficult to divert to others.

  The steam that has rotated the turbine is liquefied by the condenser. The condenser has a cooling function using cooling water or the like, and the steam is liquefied by this cooling function. The water obtained by liquefaction is sent to a cooling tower through a hot water pump, used again for the cooling function in the condenser, and finally returned to the ground. Further, the condenser is provided with a gas extraction device for extracting gas from the steam. The extracted gas is discharged from the cooling tower. Even in the binary power generation system, the basic concept and configuration are the same except that some elements are different.

  As described above, the basic idea of the conventional geothermal power generation apparatus is to separate the hot water liquid and the steam and use only the steam for rotating the turbine. For this reason, various other elements are required or a large-scale apparatus is required. In particular, since hot water is assumed to be reduced, it is necessary to use a geothermal reservoir that is different from the hot spring use source in order to process the rights with the hot spring use right holder, in order to ensure cost effectiveness. However, the installation location of the geothermal power generation device has to be limited or large.

(Overview)
The general outline of the thermal steam power generator according to Embodiment 1 will be described with reference to the prior art as a reference example.

  FIG. 2 is a perspective view of the thermal steam power generator according to Embodiment 1 of the present invention. FIG. 3 is a side view of the thermal steam power generator according to Embodiment 1 of the present invention. FIG. 3 shows a state in which the thermal steam power generator 1 shown in FIG. 2 is viewed from the side. The thermal steam power generator 1 includes a mixed hot water pipe 2, a mixed hot water turbine 3, a steam turbine 4, a rotor 5, and a hot water reflux path 6 as basic elements. In addition to these basic elements, FIG. 2 includes a partition wall 7, a hot water container 8, a steam pipe line 9, a condenser 10, a cold water circulation path 11, a storage container 12, and a steam discharge pipe line 13.

  The mixed hot water pipe 2 supplies hot water from a source and mixed hot water and water vapor. For this reason, the mixed hot water pipeline 2 is finally connected to an underground source, and supplies the mixed hot water from the underground source to the main body of the thermal steam generator 1. An arrow A shown in FIG. 2 indicates a moving path of the mixed hot water supplied through the mixed hot water pipe 2.

  The mixed hot water turbine 3 is rotated by mixed hot water supplied from the mixed hot water pipe 2. Since the mixed hot water pipe 2 has an injection pressure of mixed hot water from the ground, the mixed hot water pipe 2 supplies the mixed hot water to the mixed hot water turbine 3 with this injection pressure. The injection pressure is applied to the hot water turbine 3. The mixed hot water turbine 3 is rotated by this injection pressure. The mixed hot water turbine 3 transmits the rotation to the rotor 5.

  A partition wall 7 is provided between the mixed hot water turbine 3 and the steam turbine 4. The partition wall 7 supplies hot water obtained by rotating the mixed hot water turbine 3 out of the mixed hot water supplied from the mixed hot water pipe 2 to a hot water container 8 installed under the mixed hot water turbine 3. Lead. Since the hot water container 8 is installed under the mixed hot water turbine 3, the hot water naturally reaches the hot water container 8. Further, the partition wall 7 guides the steam contained in the mixed hot water to the steam turbine 4.

  The partition wall 7 is a wall that partitions the mixed hot water turbine 3 and the steam turbine 4. The side view shown in FIG. 3 is easier to grasp. In FIG. 3, a partition wall 7 is a portion surrounded by a thick line so as to partition the mixed hot water turbine 3 and the steam turbine 4. As can be seen from the perspective view of FIG. 2, the partition wall 7 partitions the region where the mixed hot water turbine 3 rotates (enclosed by the box-shaped member) and the steam line 9. That is, the steam turbine 4 exists inside the steam pipe 9.

  The partition wall 7 has a round opening 71 shown in FIG. 3, and this opening 71 allows the mixed hot water turbine 3 and the steam turbine 4 to communicate with each other. Of the mixed hot water that has rotated the mixed hot water turbine 3, the hot water falls into a hot water container 8 under the mixed hot water turbine 3 in accordance with the rotation of the mixed hot water turbine 3. At this time, the hot water obtained by rotating the blades of the mixed hot water turbine 3 by the partition wall 7 does not pass through the opening 71. This is because the hot water is heavy and moves in the direction of rotation of the blades and falls into the hot water container 8 as it is.

  On the other hand, the steam contained in the mixed hot water obtained by rotating the mixed hot water turbine 3 does not only follow the rotation of the blades of the mixed hot water turbine 3, and therefore reaches the steam turbine 4 through the opening 71. This is because water vapor is small in weight and can move in directions other than the rotation direction of the blades. Further, as described later, the water vapor moves so as to be sucked into the steam pipe 9 from the opening 71 due to a pressure difference generated between the inlet and the outlet of the steam pipe 9. The steam that has reached the inside of the steam line 9 rotates the steam turbine 4.

  As described above, the partition wall 7 separates the mixed hot water turbine 3 and the steam turbine 4 and separates the hot water and steam from the mixed hot water.

  The steam turbine 4 is rotated by the introduced steam. As with the mixed hot water turbine 3, the steam turbine 4 transmits rotation to the rotor 5.

  The rotor 5 generates electric power based on the rotation of at least one of the mixed hot water turbine 3 and the steam turbine 4. The generated electric power is output to a storage battery or a load by an electric wire connected to the rotor 5.

  The hot water reflux path 6 circulates at least one of hot water and steam passing through at least one of the mixed hot water turbine 3 and the steam turbine as warm water. As a result, the mixed hot water used for power generation is again effectively used for applications such as hot spring facilities. Of course, it may be returned not only to hot spring facilities but also to facilities and facilities that use hot water.

  Thus, the thermal steam power generator 1 in Embodiment 1 can generate electric power using the mixed hot water containing the hot water and the steam mixed. It is not necessary to separate the mixed hot water into hot water and steam, and not only steam but also hot water itself can be used for rotating the turbine. For this reason, since elements required in the prior art such as gas-liquid separation can be eliminated, the thermal steam power generator 1 can be reduced in size, simplified, and reduced in cost.

  In addition, since the mixed hot water used for power generation can be reduced as hot water and used as it is for hot spring facilities or the like, rights processing such as the right to acquire hot springs is facilitated. This is because hot water can be reused for hot spring facilities after power generation, so that the thermal steam power generation apparatus 1 of the first embodiment can also be installed in a source spring used for hot spring facilities.

  Moreover, since not only the gas-liquid separation device but also the conventional flasher, gas extraction device, and cooling tower can be eliminated, the thermal steam power generator 1 of the first embodiment can be further reduced in size, simplified, and reduced in cost. realizable. As described above, the thermal steam power generation apparatus 1 according to the first embodiment, in which various elements can be omitted, can be significantly reduced in size as compared with the prior art apparatus. It is easy to install even in complicated areas. In particular, hot spring areas have both the supply of hot water required for power generation and the demand for electricity generated by houses, hot spring facilities, tourist facilities, and the like.

  Since the conventional geothermal power generation apparatus was very large, it was difficult to install it in such a hot spring area, and it was necessary to install it in a mountainous area or a place away from the hot spring area. In this case, there are disadvantages such as transmission costs and management costs due to the separation from the place where the generated power is demanded.

  The thermal steam power generation apparatus of Embodiment 1 can be easily installed in each of the springs scattered in the hot spring area for the reasons described above. That is, it can be installed in a hot spring area where both hot water supply and power demand are aligned. As a result, the power transmission cost and the management cost are also reduced, so that the thermal steam power generator 1 can be easily spread. In some cases, not only the power generation company but also the operator of the hot spring facility can install and manage the thermal steam power generator 1. In this case, the thermal steam power generator 1 is more likely to spread.

(Description of operation and details of each element)
Next, the operation of the thermal steam power generator 1 and details of each element will be described with reference to FIGS.

(Supply of mixed hot water by mixed hot water pipeline)
The mixed hot water conduit 2 sucks up the mixed hot water heated by the geothermal heat from the underground hot water reservoir. For example, one end of the mixed hot water pipe 2 is connected to the hot water reservoir, and the mixed hot water pipe 2 sucks up the mixed hot water by the self-injection pressure of the hot water pool. Of course, not only the mixed hot water pipe 2 is directly connected to the hot water reservoir, but also the mixed hot water pipe 2 is mixed by connecting the boring pipe bored to the hot water reservoir and the mixed hot water pipe 2. The hot water may be sucked up and supplied to the thermal steam power generator 1.

  Further, the mixed hot water pipe 2 may not only suck up the hot water in the hot water pool by the self-injection pressure of the hot water pool, but also suck it up by an external suction pressure such as a suction pump. For example, a suction pump is installed between the mixed hot water conduit 2 and the hot water reservoir. Due to the suction pressure of the suction pump, the mixed hot water in the hot water pool is sucked and ejected from the mixed hot water pipe 2 to the thermal steam power generator 1. An arrow A in FIG. 1 is a moving path of the mixed hot water passing through the mixed hot water pipe 2.

  In addition, the description of sucking up not only indicates that an external suction pressure such as a suction pump is used, but also includes the meaning that the mixed hot water is guided to the thermal steam generator 1 when it is naturally ejected by the self-injection pressure. Yes.

  The mixed hot water conduit 2 includes a flow rate adjusting unit 21 as necessary. The flow rate adjusting unit 21 enables manual adjustment of a handle or the like, and the amount of mixed hot water supplied to the mixed hot water turbine 3 by the mixed hot water pipeline 2 can be adjusted by adjusting the opening amount. Moreover, the flow volume adjustment part 21 may adjust the quantity of the mixing hot water which the mixing hot water pipe 2 supplies by interlocking with a suction pump.

  By providing the flow rate adjustment unit 21, the amount of mixed hot water can be adjusted according to the characteristics of the source where the thermal steam power generator 1 is installed. Since the amount of the mixed hot water can be adjusted, supply of the mixed hot water suitable for power generation is realized.

  The mixed hot water conduit 2 supplies the mixed hot water to the mixed hot water turbine 3. By supplying the mixed hot water, the pressure that the mixed hot water pipe 2 has at the time of supply can be applied to the mixed hot water turbine 3. For this reason, for example, when the mixed hot water pipe 2 supplies the mixed hot water by the self-injection pressure of the hot water pool, the mixed hot water pipe 2 applies the self-injection pressure to the mixed hot water turbine 3. Alternatively, when the mixed hot water pipe 2 sucks up the mixed hot water using the external pressure of the suction pump, the mixed hot water pipe 2 applies a pressure corresponding to this external pressure to the mixed hot water turbine 3. Will be granted.

  The mixed hot water conduit 2 is a pipe-shaped conduit formed of a material such as metal, alloy, or resin. In order to cope with mixed hot water sucked up in a hot spring resort or the like, it is preferable to have high durability. In particular, since the mixed hot water often contains a hot spring-specific component such as a sulfur content, it is also preferable that the mixed hot water conduit 2 has durability against these hot spring-specific components.

  In addition, it is also preferable that the mixed hot water pipeline 2 has a plurality of units connected by a joint. For example, the unit connection is suitable when it is necessary to form the mixed hot water conduit 2 according to the drilling depth.

(Rotation of mixed hot water turbine)
The mixed hot water turbine 3 receives these pressures by injection of mixed hot water, which is a mixture of hot water and steam. With this pressure, the mixed hot water turbine 3 rotates. The rotation of the mixed hot water turbine 3 is transmitted to the rotor 5, and the rotor 5 generates power by the rotation of the mixed hot water turbine 3.

  The mixed hot water turbine 3 has blades that receive the mixed hot water and a rotating shaft that rotates the blades. With the pressure of the mixed hot water applied to the blade, the blade rotates on the basis of the rotation axis. The rotation shaft transmits the rotation to the rotor 5. The shape of the blade may be various, but the surface of the blade may be formed so as to obliquely intersect the rotation axis so that the pressure of the mixed hot water is easily received. Or the surface of a blade | wing may be formed in parallel with the rotating shaft. In any case, it is preferable that the surface of the blade is oriented in the hot water supply direction of the mixed hot water conduit 2. This is because the mixed hot water turbine 3 easily rotates depending on the orientation of the blade surfaces.

  The mixed hot water turbine 3 is preferably covered with a box-shaped member. 2 and 3 both show a state in which the mixed hot water turbine 3 is covered with a box-shaped member. Since the mixed hot water is injected into the mixed hot water turbine 3, the surrounding box-shaped member can prevent the injected mixed hot water from scattering around. It is suitable for ensuring the safety of workers and surroundings.

  It is also preferable that the outlet of the mixed hot water pipe 2 and the rotation shaft are slightly shifted so that the mixed hot water turbine 3 can be easily rotated by jetting the mixed hot water. For example, the rotating shaft may be slightly above or slightly below the jet outlet of the mixed hot water conduit 2.

  The rotational speed of the mixed hot water turbine 3 is determined by the pressure and momentum of the supplied mixed hot water, but it is also preferable to determine the maximum rotational speed according to the electric power to be generated.

  The mixed hot water turbine 3 is formed of a material such as a metal, an alloy, or a resin. In any case, like the mixed hot water pipeline 2, it is preferable to have high durability against heat and hot spring specific components.

  The mixed hot water obtained by rotating the mixed hot water turbine 3 is a liquid (hot water) contained in the mixed hot water. The hot water container 8 provided below the mixed hot water turbine 3 by the partition wall 7 and surrounding members. Led to. The hot water container 8 is a container that temporarily stores hot water obtained by rotating the mixed hot water turbine 3. The hot water container 8 moves the hot water stored in the storage container 12, and finally, The warm water is refluxed through the warm water reflux path 6.

  The partition wall 7 can separate hot water and steam by partitioning a box-shaped member including the mixed hot water turbine 3 and a steam pipe 9 including the steam turbine 4. This mechanism is as described above.

  The hot water container 8 is installed under the mixed hot water turbine 3. This is because the hot water used for the rotation of the mixed hot water turbine 3 is accommodated. Therefore, if the hot water is installed under the mixed hot water turbine 3, the hot water is reliably accommodated. Moreover, the hot water container 8 is connected to the storage container 12 by a pipe line or a communication port.

(Rotation of steam turbine)
The mixed hot water rotates the mixed hot water turbine 3 to move the hot water that is liquid to the hot water container 8 by the partition wall 7. On the other hand, the partition wall 7 guides the steam contained in the mixed hot water to the steam turbine 4. The steam that reaches the steam turbine 4 leaves an injection pressure, and rotates the steam turbine 4. That is, the steam pressure rotates the steam turbine 4.

  The steam turbine 4 is provided inside the steam line 9. The steam that has reached the steam line 9 through the opening 71 of the partition wall 7 has a constant injection pressure as described above. In addition, the condenser 10 connected to the steam line 9 is provided with a cold water circulation path 11, and the water vapor is liquefied in the condenser 10 by the rapid cooling of the water vapor by the cold water circulation path 11. To do. Due to the rapid physical change of water vapor from gas to liquid, the pressure difference between the inlet of the steam line 9 (around the steam turbine 4) and the outlet of the steam line 9 (region close to the condenser 10) is increased. Arise. That is, the pressure at the inlet of the steam line 9 is high and the pressure at the outlet of the steam line 9 is low. In some cases, the interior of the condenser 10 drops to a pressure close to vacuum.

  Due to this pressure difference, the water vapor that has reached the steam line 9 through the opening 71 moves inside the steam line 9 at a strong pressure and speed. Steam having this pressure and speed causes the steam turbine 4 to rotate.

  The rotation of the steam turbine 4 is transmitted to the rotor 5, and the rotor 5 generates power by the rotation of the mixed hot water turbine 3. Since the rotation of the steam turbine 4 is transmitted to the rotor 5 together with the rotation of the mixed hot water turbine 3, the amount of power generation in the rotor 5 is increased.

  Further, the rotating shaft of the steam turbine 4 may be the same as the rotating shaft of the mixed hot water turbine 3. In the same case, the rotation of the mixed hot water turbine 3 and the steam turbine 4 is combined to rotate one rotating shaft. The rotation of this one rotating shaft is connected to the rotor 5, and power generation by the rotor 5 is performed. Thus, the rotation force (number of rotations) that can be applied to the rotor 5 is increased by the combined rotation of the mixed hot water turbine 3 and the steam turbine 4 that are the two turbines. In this case, the steam turbine 4 may be understood as assisting the rotation of the mixed hot water turbine 3. Alternatively, the mixed hot water turbine 3 is initially rotated to induce the rotation of the rotation shaft, and then the steam turbine 4 is rotated to ensure the necessary number of rotations for the rotor 5. It may be grasped.

  Of course, the mixing hot water turbine 3 and the rotating shaft of the steam turbine 4 do not have to be the same. Due to the different rotation shafts, the rotation of the mixed hot water turbine 3 is transmitted to the rotor 5, and separately, the rotation of the steam turbine 4 is transmitted to the rotor 5. The rotor 5 receives power from each rotating shaft and generates power. By providing each rotation, the amount of power generated by the rotor 5 increases.

  The steam turbine 4 has blades that receive water vapor and a rotating shaft that rotates the blades. With the pressure of the mixed hot water applied to the blade, the blade rotates on the basis of the rotation axis. The shape of the blade may be various, but the surface of the blade may be formed so as to obliquely intersect the rotation axis so that the pressure of water vapor is easily received. Or the surface of a blade | wing may be formed in parallel with the rotating shaft. In any case, it is preferable that the surface of the blade is oriented in the supply direction of the mixed hot water conduit 2. This is because the steam that reaches the partition wall 7 also tends to collide with the steam turbine 4 in the supply direction of the mixed hot water pipe 2.

  The steam turbine 4 is also preferably covered with a box-shaped member. At this time, the steam turbine 3 is preferably covered with a box-shaped member together with the mixed hot water turbine 3. 2 and 3 both show a state in which the steam turbine 4 is covered with a box-shaped member. Since steam is obtained from mixed hot water, its temperature is very high. Since the surrounding area is covered with a box-shaped member, the risk of working with high-temperature steam is reduced. For this reason, it is preferable that the box-shaped member has heat resistance. Also, low thermal conductivity is preferable from the viewpoint of workability and safety.

  The rotational speed of the steam turbine 4 is determined by the pressure and momentum of the supplied steam, but it is also preferable to determine the maximum rotational speed according to the electric power to be generated.

  As with the mixed hot water turbine 3, the steam turbine 4 is formed of a material such as a metal, an alloy, or a resin. In any case, it is preferable to have high durability against heat and hot spring specific components.

  As described above, the steam containing the mixed hot water separated by the partition wall generates electricity by rotating the steam turbine 4. The steam is output to the steam line 9 after rotating the steam turbine 4 by the injection.

(Steam line)
The steam turbine 4 outputs the steam used for the rotation to the steam line 9. The steam line 8 is connected to the condenser 10 from the steam turbine 4. With this connection, the steam line 8 moves the steam to the condenser 10 for condensing the steam. Arrow B indicates the movement path of water vapor. The steam that has rotated the steam turbine 4 moves from the steam turbine 4 to the condenser 10 along the movement path indicated by the arrow B.

  The steam line 9 has a shape for guiding water vapor to the condenser 10. As shown in FIG. 2, the steam line 9 is also preferably curved. The steam turbine 4 is formed perpendicular to the horizontal plane, whereas the condenser 10 is formed parallel to the horizontal plane due to its nature. For this reason, the steam line 9 is preferably curved or bent in order to connect the two.

  Moreover, since the steam line 9 moves hot water vapor | steam, it is preferable that heat resistance is high. In addition, it is also preferable that the thermal conductivity is low. These are for ensuring the safety of the worker.

  The steam line 9 is made of metal, alloy, resin, or the like. The outer wall may be painted or coated.

  When the amount of steam supplied to the steam turbine 4 is larger than the amount of steam condensed in the condenser 10, the steam in the steam line 9 becomes excessive. For this reason, it is also preferable that the steam line 9 includes a steam output line 13. In the steam output line 13, the water vapor overflowing in the steam line 9 (or the condenser 10) may be discharged from the steam output line 13 to the outside. The steam output line 13 includes an adjustment valve. By adjusting the opening and closing of the adjustment valve, the steam output line 13 releases water vapor to the outside.

  Alternatively, the steam line 9 includes a pressure gauge, and it is also preferable that this pressure is interlocked with the flow rate adjusting unit 21 of the mixed hot water line 2. The amount of water vapor that overflows in the steam line 9 and the condenser 10 is determined by the amount of mixed hot water supplied through the mixed hot water line 2. If the amount of mixed hot water supplied is large, the amount of water vapor naturally increases, and the amount of water vapor in the steam line 9 and the condenser 10 also increases, which tends to overflow. On the other hand, if the amount of mixed hot water to be supplied is small, the amount of water vapor is naturally reduced, the amount of water vapor in the steam line 9 and the condenser 10 is reduced, and it is difficult to overflow.

  On the other hand, if the amount of the mixed hot water supplied is small, the rotational speeds of the mixed hot water turbine 3 and the steam turbine 4 are reduced, so that the power generation amount is small. For this reason, it is better that the supply amount of the mixed hot water is as large as possible. If it becomes too much, steam will overflow in the steam line 9 and the condenser 10. In order to achieve this balance, the flow rate adjusting unit 21 may be adjusted by the pressure of the steam line 9 measured by the pressure gauge. The amount of mixed hot water to be supplied is determined based on a balance with the amount of steam that overflows.

  As described above, the steam line 9 moves the steam obtained by rotating the steam turbine 4 to the condenser 10 while adjusting the amount of steam.

  In the steam line 9, the water vapor is rapidly condensed in the condenser 10, so that a pressure difference is generated between the inlet (opening 71 side) and the outlet (condenser 10 side) of the steam line 9. Arise. This pressure difference causes a high pressure and velocity movement of the steam, causing the steam turbine 4 to rotate.

(Condensation in condenser)
The steam line 9 moves the water vapor to the condenser 10.

  The condenser 10 is provided under the steam line 9. Of course, the condenser 10 may be provided beside or above the steam line 9. However, since the hot water obtained by being condensed in the condenser 10 is refluxed from the storage container 12, it is appropriate that the condenser 10 is provided under the steam line 9.

  The condenser 10 condenses water vapor with cooling water to obtain hot water. This hot water is not a requirement for a high temperature, but is a liquid produced by condensation of water vapor. That is, the hot water obtained by the condenser 10 is not defined by temperature conditions.

  The condenser 10 may be a part of a box-shaped member, and is a space to which the steam line 9 is connected. In this space, the condenser 10 condenses water vapor by the action of the cooling water.

  It is also preferable that the condenser 10 includes a cold water circulation path 11. The cold water circulation path 11 is provided to meander the condenser 10 and circulates cold water therein. Cold water is supplied from the outside of the cold water circuit 11. For example, a cold water supply tank is provided, and cold water is supplied to the cold water circulation path 11 from the cold water supply tank.

  The cold water circulation path 11 is provided while meandering or bending the space serving as the condenser 10. By being provided in this manner, the surface area of the cold water circulation path 11 is increased, and the contact area with water vapor and the opportunity for contact are increased. As a result, the cold water circulating through the cold water circulation path 11 cools the water vapor more efficiently and condenses the water vapor.

  In addition, the cold water circulation path 11 has a plurality of small holes, and the circulating cold water is ejected from the holes. The jetted cold water cools the water vapor while cooling the condenser 10 inside. That is, the cold water circulation path 11 can efficiently cool the water vapor by the ejection of the cold water itself.

  Moreover, since the cold water circulation path 11 circulates new cold water one after another, the cooling effect can be maintained. Even if the condenser 10 does not include the cold water circulation path 11 but includes a cold water container, the water vapor can be condensed, but if the temperature of the cold water included in the cold water container rises, the condensing capacity will decrease. . Even in such a case, if the cold water circulation path 11 is provided, cold water having a low temperature is supplied one after another.

  The condenser 10 sends hot water obtained by condensing water vapor to the storage container 12.

  It is also preferable that the condenser 10 includes a steam discharge pipe 13 that discharges excess water vapor to the outside. The steam discharge pipe 13 can discharge excess steam to the outside, maintain the pressure of the condenser 10, and prevent the steam turbine 4 from deteriorating in rotation. For this reason, it is preferable that the vapor | steam discharge pipe line 13 has a control valve and a control valve.

(Reservoir)
The storage container 12 stores hot water obtained by condensation in the condenser 10. Moreover, the hot water accommodated in the hot water container 8 is also stored according to the specification. That is, the storage container 12 collects hot water used for power generation in each of the mixed hot water turbine 3 and the steam turbine 4 as hot water. This is because the hot water after rotating the mixed hot water turbine 3 and the steam turbine 4 needs to be discharged to the outside as hot water.

  The storage container 12 may be provided under the condenser 10 and the hot water container 8. Of course, it may be provided in a place other than this, but in order to simplify the structure of the thermal steam power generator 1, it is suitable to be provided under the condenser 10 and the hot water container 8. This is because it is easy to store the hot water condensed and liquefied by the condenser 10 below the condenser 10.

  The storage container 12 is a box-shaped member and has a structure capable of storing hot water that is a liquid. For example, as shown in FIG. 2, it is a box-shaped member that is in contact with the condenser 10 on the surface. The storage container 12 may be a separate member from the condenser 10 or may be grasped as an integral member. Of course, it may be a separate member from the hot water container 8 or may be grasped as an integral member.

  In order to clarify the understanding of the elements, the condenser 10, the hot water container 8, and the storage container 12 are described. However, in the actually produced thermal steam power generation apparatus 1, these elements are separated. It is not something that needs to be grasped as. Even when grasped as a single unit, if the essence of the functions and applications described in the present specification is the same, it is determined that the manufactured thermal steam power generation apparatus includes these elements.

  The storage container 12 should just have the magnitude | size according to the electric power generation amount and specification of the thermal steam power generator 1. FIG. For example, when the power generation amount of the thermal steam power generator 1 is large, the amount of mixed hot water required is also large, and therefore it is preferable that the storage container 12 has a large capacity. On the contrary, when the power generation amount of the thermal steam power generation apparatus 1 is small, the amount of mixed hot water required is also small, so the storage container 12 only needs to have a small capacity.

  The storage container 12 may have, for example, a plurality of compartments, and the capacity may be changed flexibly by determining the compartments to be used according to the specifications of the thermal steam power generator 1.

  The storage container 12 is connected to the warm water reflux path 6. The warm water reflux path 6 can recirculate the warm water stored in the storage container 12. The hot water defined by the storage container 12 or the hot water recirculation path 6 does not have to be handled with the same definition as hot water obtained from a so-called hot water pool. In short, the hot water treated in the storage container 12 or the hot water reflux path 6 is hot water after rotating the mixed hot water turbine 3, or hot water condensed after rotating the steam turbine 4. .

  These hot waters have finished the role of rotating the turbine. That is, use of these hot water for power generation has been completed. Since these hot waters are unnecessary in the thermal steam power generator 1, it is appropriate to recirculate them through the hot water reflux path 6.

  Since the warm water recirculation path 6 is connected to the storage container 12, when hot water accumulates in the storage container 12, hot water is sent out by the pressure of the hot water. At this time, it is also preferable that the warm water reflux path 6 includes an adjustment valve 61. The adjustment valve 61 can adjust the degree of opening of the pipe of the hot water reflux path 6. By this adjustment, the warm water recirculation path 6 can adjust the amount of warm water to be delivered.

  In the state where the mixed hot water supplied by the mixed hot water pipe 2 is large, the amount of hot water to be recirculated by the hot water recirculation path 6 also increases. Conversely, in the state where the mixed hot water supplied by the mixed hot water pipe 2 is small, the amount of hot water that the hot water reflux path 6 should recirculate also decreases, so the adjustment valve 61 reduces the degree of opening of the hot water reflux path 6. .

  As described above, the hot water recirculation path 6 recirculates the hot water stored in the storage container 12. As a result, the hot water can be reused for various purposes.

  As described above, the thermal steam power generator 1 according to the first embodiment generates power by rotating two turbines using the mixed hot water sucked up. At this time, since gas-liquid separation and flasher are not required, downsizing and cost reduction can be realized. Moreover, since hot water and hot water after use (including hot water obtained by condensing water vapor) can be recycled and reused, it is difficult to cause problems even in the interest of hot springs. Together, these are easy to disseminate, unlike large-scale geothermal power generation in the prior art. In present Japan, it is urgent to disseminate power generation devices using renewable energy, and it is very suitable that the thermal steam power generation device 1 in the first embodiment is easy to spread.

  In the thermal steam power generator 1, each of the hot water container 8, the steam line 9, the condenser 10, and the storage container 12 is not limited to being physically grasped as separate elements, but is grasped as one. However, what is necessary is just to grasp | ascertain as an element demonstrated in Embodiment 1 based on the function.

  (Embodiment 2)

  Next, a second embodiment will be described.

  In the second embodiment, the case where the thermal steam power generation apparatus 1 described in the first embodiment is variously installed in a hot spring resort will be described.

  The thermal steam power generator 1 generates power using hot water. In addition, as described in Embodiment 1, since it is a very small and simple device, it is installed even in hot spring areas where there are already many right holders who use hot spring sources such as accommodation facilities and tourist facilities. Is easy.

  FIG. 4 is a schematic diagram showing the installation of the thermal steam power generator in Embodiment 2 of the present invention. FIG. 4 shows a state where the thermal steam power generator 1 is installed in a hot spring area where a plurality of source springs exist.

  In FIG. 4, two sources of the source 40A and the source 40B are shown. Both of the source springs 40A and 40B have already been set with water intake rights by hot spring use facilities and the like, and are in a state of being used for hot spring use facilities. In FIG. 4, the source spring 40A is used for the hot spring use facility 30A, and the source spring 40B is used for the hot spring use facility 30B. For example, it is used as a hot spring for bathing.

  The thermal steam power generation apparatus 1 described in the first embodiment is provided at these springs. The thermal steam power generator 1A is installed in the source 40A. The thermal steam power generator 1B is installed in the source 40B.

  The mixed hot water pipeline 2A of the thermal steam power generator 1A is connected to the source 40A. As a result, the mixed hot water conduit 2A sucks mixed hot water (source hot spring water) from the source 40A. The mixed hot water conduit 2A supplies the mixed hot water from the source 40A to the thermal steam power generator 1A. The thermal steam power generator 1A generates power using the mixed hot water of the source 40A by the function described in the first embodiment. The electric power generated by the thermal steam power generator 1A may be used, for example, in the hot spring utilization facility 30A having the right of the source 40A.

  Next, the thermal steam power generator 1A returns the hot water that has been used for power generation to the hot spring use facility 30A through the hot water reflux path 6A. That is, the hot water reflux path 6A returns the hot water (including condensed water vapor) used for power generation to the hot spring utilization facility 30A that uses hot spring water instead of returning it to the ground. That is, the hot water reflux path 6A returns hot water to the hot spring utilization facility 30A as hot spring water.

  Since the thermal steam power generator 1A only uses the mixed hot water sucked up from the source 40A as a pressure for rotating the turbine, the hot water itself is not consumed. The hot water reflux path 6A can recirculate hot water containing condensed water vapor as hot spring water to the hot spring utilization facility 30A (can be sent out). The hot water recirculated from the hot water recirculation path 6A is not altered as hot spring water. For this reason, the hot spring use facility 30A can be used in the same manner as normal hot spring water. Of course, additional processing such as hygiene management and sanitary processing may be performed in the hot spring facility 30A.

  Similarly, the thermal steam power generator 1B is installed in the source 40B. The mixed hot water conduit 2B sucks up the mixed hot water from the source 40B and supplies it to the thermal steam power generator 1B. The hot water used in the thermal steam power generator 1B is returned to the hot spring utilization facility 30B through the hot water reflux path 6B. Also in this case, the hot water used for power generation can be reused as hot spring water in the hot spring utilization facility 30B. Of course, the electric power generated by the thermal steam power generator 1B may be used in the hot spring facility 30B.

  Thus, since the thermal steam power generator 1 is small and can be easily installed for each source, the used hot water can be reused as the hot spring water in the original hot spring utilization facility. As a result, even in the hot spring resort, the thermal steam power generator 1 is installed without causing any trouble to the right holder of the source.

  The hot spring utilization facility 30 that is the right holder of the source spring 40 is in a state of using the source spring 40 for use in hot spring bathing, and a mechanism for sucking the source spring has already been installed. By simply connecting the thermal steam power generator 1 to this mechanism, it is possible to cover the power used by itself. In some cases, it is possible to sell electricity. In addition, since the hot water used for power generation can be used as the original hot spring water, the motivation for installing the thermal steam power generator 1 is increased for the owner of the hot spring utilization facility 30.

  Of course, when there is a concern about using the hot water after power generation as hot spring water, the hot water sucked up from the source 40 is first used as hot spring water, and then the hot spring water to which pressure is applied is converted into hot steam. It may be supplied to the power generator 1.

  In any case, the hot spring utilization facility 30 has high motivation to install the thermal steam power generator 1. As a result, the spread of the thermal steam power generator 1 is likely to proceed.

  In FIG. 4, the aspect in which the thermal steam power generation apparatus 1 is installed in each of the source springs 40 has been described, but one thermal steam power generation apparatus 1 may be installed in a plurality of source springs 40. Conversely, a plurality of thermal steam power generators 1 may be installed in one source 40.

  In addition, the thermal steam power generation apparatus demonstrated by Embodiment 1-2 is an example explaining the meaning of this invention, and includes the deformation | transformation and remodeling in the range which does not deviate from the meaning of this invention.
