Disclosure of the invention Problems to be solved by the invention

By the way, in the above-described conventional power generator, the working gas G is deflected to some extent by the stationary blade 204 and applied to the moving blade 203. However, the working gas G is axially displaced. Therefore, there is a problem that the moving blade 203 cannot receive the working gas G sufficiently and the conversion efficiency of the working gas G is inferior. Also, in order to improve the energy conversion efficiency as much as possible, multiple moving blades 203 and stationary blades 204 are arranged in multiple stages to make them multi-stage. However, as the device becomes larger, the structure becomes complicated and the cost becomes higher. There was a problem of high.

[0007] The present invention has been made in view of the above-mentioned problems. The structure is not complicated, and the moving blade can sufficiently receive the working gas to rotate the shaft body, thereby reducing the energy of the working gas. It is an object of the present invention to provide a power generator that improves conversion efficiency.

Means for solving the problem

In order to achieve such an object, the power generator of the present invention has a cylindrical body in which a working gas flows toward one end side of the force on the other end side, and the cylindrical body is coaxial with the cylindrical body and relatively rotatable. A shaft body supported by the shaft, and provided with a rotor blade that receives the working gas and applies a relative rotational force to the shaft body. The cylinder body is provided with a static guide that guides the working gas to the rotor blade. In a power generation apparatus that provides wings and generates power by taking out the relative rotational force between the cylindrical body and the shaft body as power,

The moving blades are arranged at equal intervals on the outer periphery of the shaft body on the other end side of the cylindrical body, and are arranged along the axial direction so as to receive a working gas derived from the stationary blade force. And a closing plate that closes one of the axial end and the other end of the array of blade groups, and an outer periphery of the array of blade groups as a working gas inlet. And the other one of the one end and the other end in the axial direction of the arranged blade group is configured as an outlet of the working gas,

A plurality of air guide plates each having a surface substantially aligned with the axial direction and arranged at equal intervals on a portion surrounding the outer periphery of the moving blade, the inner blade of the cylindrical body; And a cover plate that covers the other axial end of the installed wind guide plate group, and the axial end of the installed wind guide plate group is used as an inlet for working gas. The inner periphery of the wind guide plate group is configured as a working gas outlet. [0009] Thereby, when the working gas flows from one end side to the other end side of the cylindrical body, the shaft body is rotated via the rotor blades, and power generation is performed. In this case, when the working gas reaches the stationary blade, the working gas stops against the cover plate and the flow direction is changed in a substantially radial direction by the baffle plate. Therefore, since the working gas in the flow direction in the substantially radial direction is stopped against the blade of the blade, the blade of the blade can receive the force of the working gas sufficiently. The energy conversion efficiency is greatly improved, and the power generation efficiency is improved. . In addition, unlike the conventional case, it is not necessary to use multiple stages of stationary blades and moving blades, and the structure is prevented from becoming complicated.

[0010] Further, according to the present invention, each of the air guide plates of the stationary blade is bent in one circumferential direction, and a centrifugal force is applied to the working gas by the bent surface. As a result, the working gas is given a centrifugal force centered on the radius of curvature of the concave curved surface of each air guide plate of the stationary blade, and the flow direction is changed. Therefore, this centrifugal force is applied to the blade of the moving blade. The applied working gas stops. As a result, the blades of the rotor blades can sufficiently receive the force of the working gas, which greatly improves the energy conversion efficiency of the working gas and improves the power generation efficiency.

[0011] Further, the present invention provides an eddy current that causes the working gas flowing through the cylinder to flow in a direction along the circumference of the cylinder and to vortex so as to stop against the concave curved surface of each air guide plate of the stationary blade. It has a configuration with generation means. As a result, the working gas is centrifugally compressed as an eddy current and stops against the surface of the air guide plate, so that the working gas is reliably received by the air guide plate and the flow direction is changed in a substantially radial direction.

[0012] In this case, it is effective that the eddy current generating means is composed of a plurality of vanes that are provided radially on one end side of the shaft body and have surfaces that are substantially along the axial direction. In this way, the working gas can be reliably vortexed and centrifugally compressed.

[0013] In this case, the eddy current generating means is provided on one end portion side of the cylindrical body, the injection port for injecting the working gas, and the working gas injected from the injection port at the circumference of the cylindrical body. And a plurality of guide blades for guiding the flow along the direction. In this way, the working gas can be reliably vortexed and centrifugally compressed.

[0014] In addition, a combustion chamber that is provided on one end side of the cylindrical body and generates combustion gas as the working gas is provided. By rubbing in this way, fuel that also has a waste power such as garbage is burned. It can be burned to generate electricity.

[0015] Furthermore, one axial end of the blade group of the moving blade is closed with a closing plate, and the other axial end of the arranged blade group is configured as a working gas outlet, and the cylindrical body The inner cylinder and an outer cylinder that covers the inner cylinder are provided, the stator blade is provided in the inner cylinder, and an operating gas exhaust passage is formed between the inner cylinder and the outer cylinder. The exhaust inlet of the exhaust passage is provided at the upper end, and the exhaust outlet is provided at the lower end of the cylinder.

If it does in this way, exhaust can be made to flow out equally between an inner cylinder and an outer cylinder, and the air current in an inner cylinder can be kept favorable.

[0016] Further, the shaft body is formed of a tubular body through which outside air is passed, and a plurality of small holes for allowing the outside air to flow into the cylindrical body are provided in the tubular body, so that the outside air is supplied to the tubular body. It is called as a configuration with connected trachea. Since combustion air can be injected from the shaft, combustion air can be supplied evenly and combustion can be improved.

[0017] Further, the other end in the axial direction of the blade group of the moving blade is closed with a closing plate, and one end in the axial direction of the arranged blade group is configured as an outflow port for the working gas. A working gas passage pipe coaxial with the cylinder is provided with an injection port for injecting working gas at one end and an intake port that communicates with the outflow port and takes in the working gas from the outflow port at the other end. The cylindrical body includes an inner cylinder and an outer cylinder that covers the inner cylinder, the stationary blade is provided in the inner cylinder, and a heat source that heats the inner cylinder between the inner cylinder and the outer cylinder It is configured as a heat source fluid chamber that is filled with fluid and warms the working gas in the inner cylinder, and is provided with a cooling part that cools the working gas in the working gas passage pipe, and the working gas is formed between the cylinder and the working gas passage pipe. It is configured to circulate between and through the working gas passage pipe. As a result, it is possible to generate power using the heat source fluid heated to a high temperature.

The invention's effect

[0018] According to the power generation device of the present invention, during power generation, the working gas can be stopped against the cover plate of the stationary blade by the stationary blade, and the flow direction can be changed in the substantially radial direction by the wind guide plate. Thus, the working blade in the substantially radial direction can be stopped by the blade of the blade, and the force of the working gas can be sufficiently received by the blade blade. Therefore, it is possible to greatly improve the energy conversion efficiency of the working gas and improve the power generation efficiency. Also, As in the prior art, it is not necessary to use multiple stages of stationary blades and moving blades, and the structure is prevented from becoming complicated.

In addition, when each air guide plate of the stationary blade is bent in one circumferential direction, and centrifugal force is applied to the working gas by the curved surface, centrifugal force is applied to the blade of the moving blade. The working gas can be stopped. As a result, the blades of the rotor blades can sufficiently receive the force of the working gas. Therefore, the energy conversion efficiency of the working gas can be greatly improved and the power generation efficiency can be improved. .

In addition, if there is eddy current generating means that makes the working gas flowing in the cylinder flow in a direction along the circumference of the cylinder and vortexes against the concave curved surface of each air guide plate of the stationary blade, the working gas is provided. Since it is centrifugally compressed as an eddy current and stops against the surface of the air guide plate, the air flow can be reliably received by the air guide plate and the flow direction can be changed in a substantially radial direction.

It is configured as.

Each air guide plate 172 of the stationary blade 170 is recessed in one circumferential direction, and is configured to apply a centrifugal force to the working gas G by the recessed surface 171.

As shown in FIG. 11, an injection port 181 for injecting the working gas G is formed in one end portion in the cylinder 130, and the other end portion communicates with the outflow port 165 and operates from the outflow port 165. A working gas passage pipe 180 that is coaxial with the above-described cylinder 130 in which the inlet 182 for taking in the gas G is formed is provided. One end portion of the working gas passage pipe 180 is formed in a truncated cone shape, and the inner portion is partitioned by a plurality of volute-type partitions 183, and the inner end is formed on the circumference of the one end portion formed in the truncated cone shape. A plurality of rows of injection ports 181 facing the inner periphery of one end of the tube 131 are provided.

In the working gas passage pipe 180, a cooling unit 185 that cools the working gas G in the working gas passage pipe 180 is provided. The cooling unit 185 is erected on the end face plate 134 in the working gas passage pipe 180, and is provided with a large number of small holes 186 for injecting cooling water into the working gas passage pipe 180 as shown in FIG. Tube 187 is provided. The cooling water is supplied to the pipe body 187 through a water supply pipe 188 provided on the end face plate 134 and connected to the pipe body 187, and then flows out from the injection port 181 and then passes through the drain pipe 189 provided on the end face plate 134. Will be discharged. As shown in FIG. 14, the small hole 186 is formed obliquely so as to be jetted in the tangential direction of the circumference of the tube 187.

[0053] Further, in this power generation device, the working gas G flowing through the cylinder 130 flows in the direction along the circumference of the cylinder 130, and strikes the concave curved surface 171 of each air guide plate 172 of the stationary blade 170. The eddy current generating means 190 for making such a vortex is provided.

As shown in FIG. 11, the vortex generating means 190 is injected from the injection port 181 for injecting the working gas G provided on one end side of the inner cylinder 131 of the cylindrical body 130, and the injection port 181. And a plurality of guide vanes 191 for guiding the working gas G so as to flow along the circumferential direction of the cylindrical body 130.

Further, one end of the rotating shaft 143 of the shaft body 140 is attached to the working gas passage pipe 180. An acceleration fan 192 that accelerates the flow of the moving gas G is provided.

Therefore, according to the power generation apparatus according to the fourth embodiment, power generation is performed as follows.

The heat source fluid chamber 135 is filled with a high-temperature heat source fluid L, and the inner cylinder 131 is constantly heated, and the working gas G in the inner cylinder 131 is heated. On the other hand, in the working gas passage pipe 180, cooling water is jetted from the pipe body 187, and the working gas G is cooled. As a result, the working gas G rises between the inner cylinder 131 of the cylinder 130 and the working gas passage pipe 180, enters the working gas passage pipe 180 through the stationary blade 170 and the moving blade 160, and enters the working gas passage pipe 180. And is injected from the injection port 181 of the working gas passage tube 180. That is, an air flow in which the working gas G circulates in the inner cylinder 131 is generated.

[0055] Then, due to the airflow of the working gas G, the rotating tube 145 of the shaft body 140 is rotated via the rotor blade 160, the power shaft 147 is rotated, and power generation is performed by the generator 149. . In this case, the working gas G is accelerated and lowered by the accelerating fan 192 in the working gas passage pipe 180, and is jetted from the injection port 181 of the working gas passage pipe 180, and at the same time, is guided by the guide blade 191. It is generated in a vortex swirling in one direction along the circumferential direction of the inner cylinder 131 of the body 130 and rises in the cylinder 130. At this time, the working gas G is pressed against the wall surface of the inner cylinder 131 of the cylinder 130 and is centrifugally compressed.

Then, when reaching the stationary blade 170, the working gas G strikes against the cover plate 173, and the flow direction is changed in the substantially radial direction by the air guide plate 172. In this case, as shown in FIG. 13, the working gas G is vortexed and centrifugally compressed and stops against the concave curved surface 171 of the air guide plate 172. Therefore, the operating gas G is reliably received by the air guide plate 172 and substantially in the radial direction. Since the flow direction is changed and each of the air guide plates 172 of the stationary vane 170 is bent in one circumferential direction, a centrifugal force is applied to the working gas G to change the flow direction.

For this reason, since the working gas G to which this centrifugal force is applied strikes the blade 162 of the moving blade 160 at a substantially right angle, the blade 162 of the moving blade 160 receives the force of the working gas G sufficiently. Therefore, the energy conversion efficiency of the working gas G is greatly improved, and the power generation efficiency is improved.

The working gas G impinging on the blade 162 of the rotor blade 160 flows from the outlet 165 force of the rotor blade 160. And is delivered to the working gas passage pipe 180.

[0057] In the above-described embodiment, the cylindrical bodies 30, 130 have a cylindrical force. The shape of the cylindrical bodies 30, 130 is not limited to this, and is not limited to this. A cylinder may be used. In the above embodiment, the cylindrical body is fixed and the shaft body is rotated. However, the present invention is not necessarily limited to this. The shaft body may be fixed and the cylindrical body may be rotated. In short, any configuration may be used as long as the shaft body is pivotally supported on the cylinder body so as to be relatively rotatable, and the relative rotational force between the cylinder body and the shaft body is extracted as power to generate electric power.
