Abstract

To provide a power generation system capable of miniaturizing the whole main device.SOLUTION: Since the energy power of the high mass density fluid is converted into mechanical motive power with high mass density, the conversion device can be easily miniaturized. Therefore, the low-mass density fluid and the high-mass density fluid collected in a large scale collide with each other on the surface of the channel where the high-mass density fluid has a high static and dynamic contact angle, thereby improving the energy and power conversion efficiency between the fluids.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a mass density conversion device that converts the energy power of a low mass density fluid into the energy power of a high mass density fluid, a prime mover that is connected to the device, and a power plant and power generation system that combine the prime mover. [Background technology]

[0002] Wind power generation devices that convert wind energy into power are already in practical use. However, current wind power conversion devices are unavoidably large in order to collect wind energy due to the low mass density of air. Furthermore, the device must integrate the prime mover and generator that convert wind energy power at a high position, making construction and maintenance extremely inefficient.

[0003] In other words, the low mass density of the fluid used has the drawback of forcing the device to be large in size.

[0004] Furthermore, because large blades collect large amounts of low-mass-density fluid, the prime movers and generators directly connected to the blades are often located higher than ground level in order to convert the energy and power of the low-mass-density fluid, which makes construction and maintenance extremely inefficient. Generally, in order to ensure the safety of the large blades and equipment in the air, an upper limit on fluid velocity is set, meaning that the operation of the equipment is cut off and shut off, which creates the problem of having to waste the valuable energy reserves.

[0005] As an improvement measure, if the fluid collection function and the prime mover / generator could be separated and a mass density conversion device that converts the energy power of low mass density fluid into high mass density fluid could be located on the ground, the prime mover and generator connected to the mass density conversion device could be located on the ground, which would be extremely efficient in terms of construction and maintenance, and would also easily increase the upper limit fluid speed for cut-off shutoff, making it possible to convert a large amount of energy into energy. Figure 1 shows a device that converts the mass density of a low-mass-density fluid into a high-mass-density fluid by guiding the low-mass-density fluid onto a surface-treated channel that creates a high contact angle with the high-mass-density fluid and then supplying the high-mass-density fluid onto the same channel.The system also includes a prime mover that is directly connected to this high-mass-density conversion device and performs mechanical conversion, a system that utilizes the prime mover's output, and a power generation device that is directly connected to the prime mover.

[0007] [Non-Patent Document 1] "Fluid Machinery" by Hideo Ohashi, Morikita Publishing Co., Ltd., revised in 1997 Summary of the Invention [Problem to be solved by the invention]

[0008] The problem to be solved is that in order to collect low density fluid and convert that low mass density energy power directly into energy power, the conversion device becomes large and has to be placed higher than above ground.By collecting low density fluid, guiding the collected low mass density fluid to ground and converting that low mass density fluid into high density fluid, the device can be made smaller, and the construction and maintenance of the prime mover that mechanically converts the device becomes extremely efficient. [Means for solving the problem]

[0009] When converting the energy power of a low-mass-density fluid into the energy power of a high-mass-density fluid, if the contact angle of the fluid surface in the channel through which the high-mass-density fluid is conducted is small, the high-mass-density flow cannot easily undergo surface separation. Therefore, the main feature of this invention is to conduct the high-mass-density fluid into a channel with a surface-treated surface that has a large contact angle with the high-density fluid, particularly a surface-treated channel with large static and dynamic contact angles, and cause the low-mass-density fluid to collide with the high-mass fluid, thereby efficiently converting the energy power of the low-density fluid into the energy power of a high-density fluid. [Effects of the Invention]

[0010] The mass density conversion device of the present invention, which converts the energy power of low mass density fluid into high mass density fluid energy power, has the disadvantage of being large due to the low mass density. However, by converting to high mass density, the entire main device can be made smaller, and in particular, it has the advantage of being able to be installed on the ground, making construction and maintenance easier. [Brief explanation of the drawings]

[0011] [Figure 1] FIG. 1 shows an example of a method for converting the energy power of a low-mass density fluid into the energy power of a high-mass fluid, and is an explanatory diagram for transmitting the energy power of the high-mass fluid to a prime mover. (Example 1) DETAILED DESCRIPTION OF THE INVENTION

[0012] The objective of converting the energy power of a low mass density fluid into the energy power of a high mass density fluid has been achieved with a minimum configuration and efficiently in terms of energy, power, cost, construction and maintenance. [Example]

[0013] Figure 1 is a diagram of one embodiment of the device of the present invention, which shows a mechanism for converting the energy power of (1) a low-mass-density fluid supplied from a low-mass-density fluid supply device into the energy power of (2) a high-mass-density fluid supplied from a high-mass-density fluid supply device by (3) colliding the fluid on the surface of a high-contact-angle surface-treated channel, and (4) guiding the high-mass-density fluid to a prime mover for mechanical conversion, or a system (omitted) and a power unit (omitted) for generating electricity by directly connecting to the prime mover. In addition, depending on the fluid energy and power of the (3) high-contact-angle surface-treated channel, the fluid in the high-contact-angle surface-treated channel is supplied as a (2) high-mass-density fluid supply device, and a method of (2) and (3) having multiple stages of high-contact-angle surface-treated channels is adopted.

[0016] In the above formula, the power of the fluid P is (dE / dt) is the time rate of change of the fluid kinetic energy, (dv / dt) is the rate of change of velocity over time (acceleration), (dρ / dt) is the rate of change of mass density over time, (dV / dt) is the rate of change of volume over time.

[0017] In order to efficiently improve the velocity time rate of change (acceleration), volume time rate of change, and mass density time rate of change, a large amount of low mass density fluid is collided with a high mass density fluid on a channel whose surface has been treated to create a high contact angle, and this high mass density fluid is then guided to a prime mover.This makes it possible to make the prime mover smaller, and if the prime mover is located on the ground, construction and maintenance will be easier, thereby improving overall cost effectiveness.

[0018] Generally, in a conversion device that converts energy into power, it is not possible to achieve both energy conversion efficiency and power conversion efficiency simultaneously.

[0019] Therefore, the conversion device is optimized by controlling the supply of high mass density so that when the fluid velocity is high, priority is given to energy conversion efficiency, and when the fluid velocity is low, priority is given to power conversion efficiency. In other words, optimization differs depending on the device mode.

[0020] Therefore, conversely, the conversion device may be optimized by controlling the supply of high mass density so that power conversion efficiency is prioritized when the fluid velocity is high, and energy conversion efficiency is prioritized when the fluid velocity is low. [Industrial Applicability]

[0021] In addition to being applicable to wind power generation equipment, which has become larger in recent years, it can also be applied to an integrated system that connects a prime mover connected to a fluid mass density conversion device, a power unit and generator connected to that prime mover, and control devices for both.
