Abstract
Description
The present invention relates to an axial multistage turbine, and more particularly, to an axial multistage turbine that generates power by converting a linear motion of a fluid into a rotary motion.
Turbines are machines that convert the energy of fluids such as liquids and gases into useful mechanical work. In general, the turbine is to generate a rotational power by using the kinetic energy of the fluid flowing in a straight line, by planting a plurality of vanes or wings in the rotating body and by generating steam or gas to rotate the high speed to generate power.
The gas turbine compresses air, supplies it into a closed container, and injects fuel to inject the combustion gas of high temperature and high pressure into the blade of the turbine which is a rotating body to obtain rotational force. However, the gas turbine has a disadvantage of low thermal efficiency, high fuel consumption, and complicated structure and large size of the rotating body, which requires a large space in the axial direction and thus is not easy to install.
In order to improve this problem, Korean Patent Publication No. 10-0550366 discloses an axial multistage turbine.
The axial multistage turbine is a turbine coupled to a disk through-wheel formed at a diagonal angle in one direction from the fluid inlet at the front to the fluid outlet at the rear by drilling concentric circles adjacent to a plurality of through holes on the outer side of the circular plate around the rotation axis. It has an impeller.
However, when the fluid flows into the cylinder housing discontinuously, the axial flow type multistage turbine does not affect the rotational force of the rotating body because the fluid introduced into the through hole of the circular plate is discharged to the rear of the circular plate instead of rotating the circular plate. Since the nozzle plate is fixed and the fluid is injected to the rear circular plate body, when the rotational speed of the circular plate body is faster than the velocity of the fluid injected from the nozzle, the fluid injected through the nozzle does not affect the increase in the rotational force of the circular plate body. There is a disadvantage.
In addition, the axial multistage turbine is required to change the position of the through holes in multiple stages so as to interfere with the fluid passing through the through holes in order to increase the amount of power generated, so that a large number of circular plates are required, resulting in a large manufacturing cost and manpower. This is required, and the manufacturing process is complicated because each circular plate must be matched according to the moving direction of the fluid. There is a disadvantage in that it reduces the power production efficiency.
The present invention has been made to solve the above problems, and provides an axial multistage turbine that is easy to install or manufacture and improves the power generation efficiency of the turbine by minimizing the pressure loss of the fluid flowing into the housing. There is a purpose.
In order to achieve the above object, the axial flow type multi-stage turbine according to the present invention includes a housing in which an inlet and an outlet are formed to allow fluid to flow therein, a rotating shaft rotatably installed in the housing, and installed in the rotating shaft A front impeller formed with a plurality of through holes penetrated to guide the fluid to the rear through the fluid, and fixed to the rotation shaft behind the front impeller, and rotating the fluid to rotate the rotation shaft. At least one guide groove is formed to guide in the direction, and at the end of the guide groove is provided with at least one rear impeller formed with a rear discharge port for generating a rotational force by discharging the fluid flowing along the guide groove to the rear.
The front impeller is fixed to the inside of the housing to rotatably support the rotating shaft, the through hole of the front impeller is in communication with the vertical portion and the vertical portion formed in parallel in the axial direction, the guide groove of the rear impeller It is preferable to have an inclined portion formed to be bent to guide the fluid.
It is formed to protrude in the guide groove of the rear impeller, and further comprises a plurality of resistance blades for generating a rotational force by interfering with the fluid flowing along the guide groove.
The guide groove of the rear impeller is characterized in that the branch is formed into a plurality of branches along the circumferential direction.
The rear impeller may further include a plurality of airtight holding protrusions protruding from the outer circumferential surface to maintain the airtightness between the outer circumferential surface of the rear impeller and the housing.
The rear impeller installed on the rotary shaft in a position adjacent to the outlet further includes a plurality of discharge guides protruding from the rear to guide the fluid discharged through the rear outlet to the outlet of the housing.
The front impeller according to another embodiment of the present invention for achieving the above object is fixed to the rotating shaft to rotate with the rotating shaft, the through hole of the front impeller is a vertical portion formed in parallel in the axial direction, the vertical It is in communication with the portion, and provided with an inclined portion formed to be bent to rotate the rotary shaft.
The front impeller may further include a plurality of resistance grooves or resistance protrusions formed along the circumferential direction on the upper surface of the front impeller so as to generate a rotational force by interfering with the fluid introduced into the housing.
The front impeller further includes at least one fluid guide groove for guiding the fluid flowing into the housing to the through hole of the front impeller.
The front impeller further includes a plurality of first outflow prevention protrusions protruding in a closed circuit along the circumferential direction on the upper edge of the front impeller so as to prevent the fluid flowing into the housing from flowing out to the outer circumferential surface. A second interposed between the outflow prevention protrusions and protruding in the forward impeller direction to form a closed circuit along the circumferential direction of the housing at a position opposite to the first outflow prevention protrusion so as to seal between the housing and the front impeller; It further comprises an outflow prevention projections.
The axial multistage turbine according to the present invention can be easily installed or manufactured to reduce the installation cost, minimize the pressure loss of the fluid flowing into the housing, and the flow path through which the fluid can flow continuously into each impeller The present invention provides an advantage of generating power by interfering with the fluid flowing through the flow path in multiple stages and improving the power generating efficiency of the turbine.
