Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generation turbine.

[0002]

2. Description of the Related Art It is well known that a conventional turbine sink (hereinafter referred to as a casing) is provided with a blade (impeller) and a coaxial generator is driven by using the rotation of the blade.
However, in this type of turbine, a large blade sink is equipped with a single blade, so a large energy key is required to rotate this single blade.
There is energicus. In a large casing ゛, a large amount of driving fluid (steam, air, etc.) is supplied. Therefore, there is a problem that a large pressure is applied to the blade plate to give an impact to the blade plate and that the blade plate is severely damaged. On the other hand, if the thickness of the blade plate is increased as a means for solving this kind of problem, other problems such as generation of energy loss and waste of material occur.

In order to solve the above-mentioned problem, a configuration (technical idea) in which a casing is divided into respective chambers and each of the chambers is provided with a blade is considered. As a configuration based on this technical idea, that is, a configuration in which a turbine is divided into respective chambers and a blade plate is installed in each chamber, there is a steam chamber of a steam turbine disclosed in JP-A-60-85203. . The present invention has a configuration in which a cylindrical member having a different nosple direction is provided on a cylindrical member provided in a casing having an intake / exhaust chamber, and is characterized by a smooth flow of steam with a different nosle direction. To ensure efficient operation of the vehicle.

[0004]

As described above, in the case of a conventional integrated type of turbine, the larger the size, the larger the energy energy and the greater the material waste.

[0005] Further, although the literature describes a configuration for partitioning a chamber, it has a configuration in which a wing is provided for each cylindrical member, and each cylindrical member is in communication. Therefore, since it is essentially considered to be an integral-structured chamber, there is a problem similar to that of the above-mentioned conventional integrated type.

[0006]

According to the first aspect of the present invention, the energy sink is divided into a plurality of chambers to eliminate energy loss, achieve an efficiency of approximately 80 to 90%, and achieve a small supply pressure. The purpose is to secure a large amount of power generation.

It is divided into rooms and communicates between the discharge opening of each chamber and the inlet opening of another adjacent chamber via a communication pipe, and is introduced into the inlet opening of the first chamber of each chamber. This is a power generation terminal having a configuration in which a discharge pipe is provided at a discharge opening of a last chamber, and a discharge pipe is provided at a discharge opening of the last chamber through each of the chambers from the first chamber.

[0008] The invention of claim 2 aims at achieving efficient power supply while ensuring a small supply pressure.

A second aspect of the present invention is a power generation turbine having a configuration in which the inner diameter of the introduction pipe is equal to or larger than the inner diameter of the communication pipe.

[0010] The invention of claim 3 intends to achieve efficient power generation by making the resistance to the rotating shaft substantially equal to zero.

A third aspect of the present invention is a power generation turbine having a configuration in which a rotating shaft is provided on a bearing in a floating manner.

[0012]

Embodiments of the present invention will be described below.

[0013] When a fluid such as steam, air or water is introduced into the first chamber through a pipe having substantially the same diameter as the inlet opening of the first chamber without resistance, the pressure of this fluid causes the initial chamber to become inactive. The Changha blades are rotated at high speed. When the fluid reaches approximately 2/3 of the first chamber, the fluid supplies the fluid to the next chamber through the discharge pipe from the discharge opening of the first chamber. This communication pipe has substantially the same diameter as the inlet opening of the next chamber, and has the same diameter or more as the first communication pipe so as to reduce the introduction resistance (hereinafter, the same as the same). But not limited). As described above, the next chamber is rotated at a high speed by supplying the fluid to the next chamber. Thereafter, each of the chambers is rotated at a high speed through the supply of fluid to each of the chambers in order, and the generator is driven to generate electric power. The finished fluid is discharged out of the sink cabinet through a discharge pipe connected to the discharge opening of the first chamber. The diameter of the discharge pipe is set to be substantially equal to or larger than the diameter of the first communication pipe, and the discharge pipe is discharged to the outside of the sink sink without resistance. The pressure of the introduced fluid is
It can be received by a disk, a wing plate, etc., but by dividing this case sink into each chamber by a disk, the pressure on the case sink, the disk, the wing plate, etc. can be reduced, and the thickness and structure of the case sink, etc. can be simplified.
