Description

natural aerodynamic power generation system

technical field

The invention relates to a power generation system, especially a power generation system that converts air pressure difference and temperature difference existing in the natural environment into mechanical kinetic energy.

Background technique

Humans have long had the idea of using the pressure difference or temperature difference in the natural environment to generate power, and some ideas have been implemented, such as using the chimney effect to circulate air in environmentally friendly buildings or buildings, thereby saving part of the electricity used for ventilation. Another example is to use the temperature difference between the ground and the ground to generate electricity, or directly use geothermal power to generate electricity. Just disclose a kind of (natural draft wind power generation tower) in Chinese patent CN97203981, its appearance is like a vertical tall chimney. Also disclose a kind of (generating device) in French patent FR2549157, drill a vertical deep well in the middle of the mountain, do a horizontal passage at the bottom of the mountain, be connected into an L-shaped pipeline with this deep well. Regardless of the prior art of China or France, it must have a vertical passage, using the air pressure difference and temperature difference at different heights to make the air have a natural physical phenomenon of bottom-up movement in the passage, and the generator Installed in its vertical pipeline, it uses the thrust impact of the rising airflow to push the generator to generate electricity.

The shortcoming of CN97203981 is: in order to obtain enough air pressure difference, "chimney" must be high enough and very vertical, otherwise it is easy to collapse, so it can be imagined that the difficulty of implementation is very high, and it is not practical. However, the construction difficulty and investment cost of the vertical deep well and horizontal passage in FR2549157 are higher, and the vertical deep well in the middle of the mountain and the horizontal passage at the bottom of the mountain are difficult to change once formed, which is not conducive to adjustment and maintenance. The two prior technologies also have a common shortcoming, that is, once the environment of their air outlets and air inlets changes, the entire device cannot be reused when it needs to be changed because it is an immovable building. Moreover, the function is only to generate electricity, which is environmentally friendly. The effect is not very obvious.

Contents of the invention

The purpose of the present invention is to provide a natural aerodynamic power generation system with low construction cost and flexible construction. In addition to power generation, it can also simultaneously convert waste heat from the bottom of high-rise buildings, waste heat from factories, and even busy aircraft that generate a lot of waste heat. The exhaust heat of the field is extracted to obtain environmental protection and power generation benefits. It can also reduce the chance of wind shear, tornado, hail and violent lightning at the airport, and reduce the danger of bad weather to slow and low-flying aircraft.

In order to achieve the above object, the purpose of the present invention is achieved in this way: a natural aerodynamic power generation system is characterized in that: it comprises a basic pipeline with a tube body seal with an air inlet part and an air outlet part, and the tube body is provided with For the wind power generator, there is a pressure difference between the air inlet part and the gas outlet part, which generates air flow to drive the wind power generator to run. (Tornadoes are also caused by various factors in the natural world that cause drastic changes in air pressure. The air pressure at high altitudes is low and the air pressure on the ground is high, resulting in the phenomenon that the low pressure forcefully absorbs the high-pressure air.) The purpose of the pipe seal is to directly connect the high and low pressures, resulting in Rapid airflow, the pipeline is like a straw, the endless high-altitude and strong low pressure suck the low-pressure airflow directly to the high altitude through the pipeline.

The pipe body of the pipeline undulates with the shape of the terrain or the building to which it is attached. The air inlet part of the pipeline is set at a low-altitude position with high air pressure, and the air outlet part is set at a high-altitude position with low air pressure, so that there is an air pressure difference between the two to generate the airflow that drives the wind turbine to operate.

The present invention utilizes the pipeline including the air inlet part and the air outlet part with air pressure difference and the sealed pipe body, and lays up and down along the height direction of the building or the environmental terrain and turns left and right, and it does not need to implement extremely difficult smoke or smoke. Unchangeable deep wells and other buildings, thus greatly reducing construction costs; the whole system can utilize most of the existing high-rise buildings or flexibly additionally build with the terrain of the natural environment, and can also be dismantled and relocated when needed; the present invention utilizes natural The aerodynamic power generation can save energy. It can also extract waste gas and waste heat from parking lots, tunnels, factories and underground mines at the bottom of high-rise buildings, promote environmental protection, and reduce the danger caused by hot air in large facilities such as airports.

Detailed ways

As shown in Fig. 1, the present invention is a kind of natural aerodynamic power generation system, comprises a pipe body 13 sealing with air inlet part 11 and air outlet part 12 and can be the basic duct 1 of any shape, and duct 1 is made up of section It is assembled with pipes, so it is very convenient for installation or daily maintenance or disassembly and relocation. The pipe body 13 undulates with the terrain or the shape of the building it is attached to, such as going uphill, downhill, turning left and right, passing through mountains, plateaus or plains in the middle, buried on the ground or underground, etc., and can also be composed of two or more branch pipes in the middle The basic pipeline 1 is designed according to the actual situation. Pipe body 13 is provided with one or more generator rooms 131, and one or more generators 2 are installed in the generator rooms, and the longer the pipeline, the more generator rooms can be built. The air inlet part 11 of the pipeline is set at a low altitude position with high air pressure, and the air outlet part 12 is set at a high altitude position with low air pressure, so there is an air pressure difference between the two. The high-pressure air at the place generates a huge suction force, quickly sucks it into the pipeline and flows towards the direction of the air outlet part 12. The air pressure difference is so large that the generated airflow is enough to drive the wind turbine to rotate and generate electricity. There are many high mountains thousands of meters high on the earth, so when the present invention is applied, the height difference between the air inlet part 11 and the air outlet part 12 can reach several kilometers, and a very large air pressure difference can be achieved. The greater the height difference between the outlet and the inlet of the pipeline, the greater the air pressure difference and the greater the power.

As shown in Figure 2, a widened machine room 131 is provided in the pipe body 13, and the machine room includes a widened main pipeline 132 installed with a wind turbine 2, a widened secondary pipeline 133, a pipeline door 134 for switching airflow paths, and a machine room. Door 135. During normal power generation, the pipeline door 134 closes the auxiliary pipeline 133, and the air flow flows through the main pipeline 132. When the generator 2 needs to be repaired, inspected or maintained, it is entered by the machine room door 135, and the pipeline door 134 is controlled to close the main pipeline 132, so that the generator 2 stop, the air flow is switched to flow in the auxiliary pipeline 133, and continue to maintain the gas source of other generator rooms. After the repair, inspection or maintenance work is completed, the pipeline door 134 is restored, and the pipeline 132 is returned to the working state.

The air inlet portion 11 of the pipeline can be provided with two or more than two inlet branch pipes 111 whose total cross-sectional area is greater than that of the basic pipeline. On the air outlet portion 12 of the basic duct, an upper cover device can also be added. And the air inlet of branch pipe 111 is provided with dust-proof device, for example several layers of metal wire dust-proof mesh cover (seeing figure 4).

17 among Fig. 1 is a high mountain of about 3000 meters, and basic pipeline 1 can be laid along the hillside, and each waste gas of the buildings of air inlet position, waste heat source can be received on the pipeline 1 by the branch pipeline 111 of air inlet part 11, The air inlet part 11 is actually a plurality of suction ports composed of a plurality of branch pipes 111, and is located at the place where exhaust gas needs to be sucked.

The output cables of electric energy are laid in the pipeline 1 .

Figure 5 is a schematic diagram of another embodiment of the invention, this embodiment being used in a single building. Main body among the figure is the building 16 (building) of high about 150 meters, and the lower end of pipeline 1 of the present invention is connected to building bottom parking lot, restaurant cooking exhaust pipe by many branch pipelines 111 distribution, between the central air-conditioning radiator Exhaust gas and waste heat sources are connected to the air inlet part 11, and the top of the building is the air outlet part 12 of the pipeline 1, and one or more wind power generator houses 131 as shown in Figure 2 are installed in a suitable position in the pipeline 1. Because there is a height difference between the air inlet part 11 and the air outlet part 12 and waste heat sources such as building parking lots, central air-conditioning radiators, restaurants, etc., the air pressure and temperature of the air inlet part 11 are higher than the air pressure and temperature of the air outlet part 12. temperature. Therefore, the air flow from the air inlet part 11 to the air outlet part 12 is formed, and the air flow force pushes the wind generator 2 in the pipeline 1 to generate electricity, and the air flow entering the pipeline 1 is free, and the dirty air can also be sucked away simultaneously. Improve the air quality of the above places.

The present invention can also be applied to areas where thermal air currents frequently occur in large-scale facilities of airports to reduce the probability of wind shear, tornado and hail. For example, the busy and hot Hong Kong Airport is located south to the sea and north to the Asian continent, while the airport is equivalent to an artificial hard ground plain. This geographical environment is a cloudy area especially in summer. The high-pressure thermal airflow formed by the hot gas generated by other equipment, the cloud layer is squeezed by the high-pressure and hot updraft to increase the density and thickness and is forced to be higher, the temperature difference and pressure difference between the upper and lower clouds are further aggravated, and thunderstorms and hail are likely to occur Once a thunderstorm or hail falls, the cloud layer and the air under the cloud layer will be cooled and shrink sharply, resulting in a sudden change in air pressure and temperature, which will lead to the formation of wind shear or tornado. Apply the present invention to the airport, if there is no high mountain nearby, just build one or more long-distance large-scale pipelines with large high and low pressure differences and can generate electricity, and distribute a large number of branch pipes of the air inlet part 11 around the airport, especially in hot In the waste gas area, the air outlet part 12 is installed on a high mountain in the distance, which continuously sucks away the hot air in the airport area, effectively reducing the formation of wind shear, tornado or hail caused by the accumulation of hot air flow, and continuously generating electricity. Turn harm into profit.

The theory of the present invention is based on the power source is endless and stable powerful suction from high altitude, so the pulling force (suction) rather than the thrust (rushing) theory of the above two inventions has been used, and the theory of pulling force can be used to turn the pipeline and The generator can be installed in the flat pipeline. Inside the tubes, the thrust is only effective enough to move a generator. The air volume and flow rate on the strong low-pressure suction in the sealed basic pipeline are balanced and stable. Pull is equivalent to slow acceleration. A generator with fewer wind blades is installed in the widened pipe of the generator room, and the diameter of the wind blade is appropriately smaller than that of the widened pipe, as shown in Figure 3. The diameter of the main pipeline 132 of the generator room 131 is larger than that of the basic pipeline 1. Because the pipeline in the generator room is enlarged, the airflow from the basic pipeline to the widened pipeline 132 at high speed will be slower and the pressure of the airflow will be slightly lower, which can offset the airflow meeting the power generation. Strong pressure and sudden resistance during the machine. Because the blades of the generator are pulled by the suction to rotate, the suction is soft and slow acceleration, so the generator is slowly accelerated until it is equal to the airflow velocity in the widened duct. The density of gas is lower than that of liquid, and the acceleration, deceleration and rotation are strong. When the endless and powerful airflow meets the fan blades in the pipeline, it will not spread out, but will only accelerate and rotate immediately, driving the fan blades to rotate. Therefore, the basic pipeline The flow and velocity of the airflow will not be reduced by the number of generators.
