Description

Hydraulic power generating system with vacuum draft tube

In order to obtain high-efficiency power, a large drop was required. To this end, the aberration was installed at the lowest level above the surface of the final waterproofing lead. The safety margin and structural space were installed from the company, and the safety margin was free fall loss.

The aberration is installed at the height of 10M above the final waterproof lead surface, and a vacuum draft tube is installed to obtain a complete drop, and the water of the waterproof lead is drawn to the outlet side of the aberration by vacuuming the air in the vacuum draft tube. This water has potential energy, so the vacuum pressure is formed by falling down due to gravity, and the water flow with the vacuum pressure added to the water acting on the nozzle in the aberration chamber rotates the aberration. Is released.

1 is a system diagram showing a case where the aberration is higher than the upper reservoir, and this type of system is used for waterfalls and falls of 1OM or less. The lower end of the suction water pipe 2 and the vacuum suction pipe 7 should be immersed in water to be isolated from the air. When the controller 5 is set to a predetermined pressure and the vacuum pump 4 is operated, the suction water pipe 2 ) And the water in the vacuum suction tube 7 is filled with water, and the water filled in the suction water pipe 2 is sucked out by the nozzle 10 and the vacuum suction tube 7 has a predetermined pressure of the controller 5. The water is filled as much as the set value and has potential energy, and a vacuum pressure is formed by the force of water to fall downward, and the water exiting the nozzle 10 by this vacuum pressure has a viscosity, specific gravity, and inertia. It blows straight in a discharge direction, turns the aberration 3, and flows into the waterproof lead 9 through the vacuum draft tube 7 by the gravity of the water in the vacuum draft tube 7. The effective drop is the drop which is obtained by subtracting the water wheel rotation space 14 from the total drop 16. A full drop can be used when using reaction aberrations. Orifice (15) when the flow rate in the suction pipe (2) is slow, if the air is filled because it can interfere with the flow of water to discharge the residual air, to facilitate the flow of water. In this system, the aberration (3) is removed, and the suction water pipe (2) and the vacuum draft pipe (7) are directly connected to adjust the vacuum pressure at the height of the dam below 10M. Can be used as a channel that can discharge a large amount of water over obstacles and a lock with zero leakage rate, and a vacuum draft tube (7), aberration chamber and suction channel (2) are used as transparent materials and emit light. It can be used as learning materials, elegant indoor and outdoor decorations, and motorized playground equipment in parks by using blades. Gravity-type water pipe (1) of Figure 2 is a general water pipe to send the water of the upper reservoir to the water wheel (3) by gravity, so far all the power of the hydroelectric power has been powered only by the pressure of this gravity water pipe (1) The design uses the vacuum draft tube 7, and the vacuum draft tube drop 13 is added to the gravity water pipe drop 11 to return the aberration 3 to a system of this type in a drop of 10M or more. The effective drop is the sum of the gravity water pipe drop (11) and the vacuum draft pipe drop (13). Example 1) For example, hang a spring scale on the ceiling and attach a weight of 10 kg. Under the weight, attach a weight of 10 kg connected to the rubber band again. The instructions for the scale are 20 kg, and if you cut the rubber band with the weight below, the instructions are 10 kg. In Example 1), the above-mentioned additional gravity water pipe drop (11) above, and the additional vacuum suction pipe drop (13) below, and the rubber band connecting the upper and lower weights correspond to the vacuum pressure of the aberration chamber. For example, in the natural state, opening the nozzle 10 at the bottom of the gravity-type water pipe 1 rotates the aberration 3 as the water is discharged. When the vacuum pump 4 is operated, the vacuum pressure acts on all parts of the aberration chamber. The two vacuum suction tubes 7 and the nozzles 10 which are dynamic are changed to fill the vacuum suction tube 7 with the vacuum suction pressure as much as the water filled in the vacuum suction tube 7. A suction pressure acts on the water flow of the nozzle 10 being discharged, and rapidly discharges the aberration 3 by the high pressure water flow and discharges downward while maintaining the water level of the vacuum suction tube 7. When the flow rate of the nozzle 10 is suddenly changed, the pressure in the aberration chamber is greatly changed in the water level in the vacuum draft tube 7, because the system is a continuous system in an enclosed space. In Example 1), open the control valve (6) to release the vacuum pressure by opening the control valve (6) to release the vacuum pressure, and then the water level of the vacuum suction tube (7) is the water level of the waterproof lead (9). The suction force that falls and acts on the nozzle 10 is also lost, so that only the gravity-type water pipe drop 11 can be used. Setting the water wheel rotation space 14 while seeing the loss of the free fall allows the vacuum layer to connect the top and bottom drops while avoiding friction between the aberration 3 and water and alleviating the impact. Using the pipe (7) to set the height of the aberration (3) at a height of about 10M from the surface of the waterproof lead (9), even if the complete drop is obtained, the same as the effect of installing the aberration (3) on the waterproof lead surface. The vacuum pump 4 operates at initial operation and fills the water in the vacuum draft tube 7, and during normal operation, the water absorbs air due to a fluid collision between water and air or discharges bubbles downward due to the flow rate of flowing water. Therefore, it is influenced by the controller 5, but operates extremely intermittently. In general, the vacuum pressure is excessive so that a small amount of air is put in order to maintain a predetermined pressure, so that the vacuum pump 4 is rarely operated. . The discharge efficiency is good when the water level of the vacuum draft tube 7 is maintained as high as possible, but when the water level is excessively high, the vacuum pressure is excessively lowered so that the water in the vacuum draft tube 7 is vaporized to increase the operation rate of the vacuum pump 4. This can cause energy waste, but vaporized water can be used as drinking water and the water level or atmospheric pressure must be checked before determining the water level. If the vacuum pressure in the vacuum evacuation tube 7 is excessively low, the control valve 6 is opened under the control of the controller 5 to open the pressure and the water level within the set value range due to the inflow of air. In addition, if there is a margin of free fall, the water level in the vacuum draft tube 7 is adjusted by changing the set value of the controller 5, and the rotation speed and output of the aberration 3 can be adjusted by the change of the vacuum draft tube 13. Do. Since the air in the vacuum evacuation tube 7 is sucked in and discharged by the vacuum pump 4, the vacuum evacuation tube 7 can be used as the pump pump intake pump even in the case of pumped power generation, so that the pump does not need to be installed below the lower reservoir. . .

Since it is possible to use the dead drop completely, the device can be miniaturized with high water pressure and the power generation efficiency is increased by maximizing the effective drop utilization, so the non-profitable drop can be used with high profit, and the aberration can be installed at the height of 10M above the waterproofing water level. It is safe from floods, waves, and aberrations, and it is highly applicable to the miniaturization, supersized and waterways, locks, elegant indoor and outdoor decorations, and overcomes waves. It is especially effective for small-scale power generation, low drop-off, small-scale power generation, development of dead energy source, and it is possible to install additional vacuum draft tube and vacuum device in the power plant installed by hose or simple pipe piping at low cost. It will contribute to the creation of a clean global environment by maximizing the use of hydro resources on the planet.
