Description

wind power system

technical field

The present invention relates to a wind power generation system, more precisely, relates to a wind power generation system which utilizes the temperature difference and convection between hot and cold air formed by heat to generate wind power.

Background technique

At present, the methods used for large-scale power generation mainly include thermal power generation, hydropower generation and nuclear power generation. The disadvantages are high cost, low efficiency and serious environmental pollution. The methods used for small-scale power generation mainly include solar power generation, wind power generation, tidal power generation and geothermal power generation. The existing problem is that the power generation is small and unstable, which cannot meet the growing demand for power generation.

The 12th page of the 1983 No. 2 issue of "Solar Energy" magazine published by the editorial department of "Solar Energy" in Beijing (author: Wen Junzhou) reported a kind of solar air flow power generation tower designed by Dr. Philip Carlson. The principle is to use a pump to pump seawater to the top of the tower along the pipeline, and spray the water in the form of mist through the spray device. The water mist evaporates rapidly in the dry hot air, cooling and moistening the surrounding air, thereby increasing its density. The cooled tower top air sinks along the cylindrical tower cavity, forming a continuous downward airflow. Because the tower body is very high, the cylindrical tower cavity has a guiding effect on the airflow, which accelerates the speed of the airflow. In the lower part of the tower, the tower cavity is divided into an annular channel by a huge airflow cover, whose cross-section becomes smaller rapidly, and the speed of the airflow passing through here is further increased, thereby generating strong wind. In the circular channel, 10 turbine generator sets are evenly arranged along the surrounding direction, which rotate and generate electricity under the impetus of high airflow. The air flow power tower has a height of 2,400 meters, a top diameter of 274 meters, and a maximum output power of 2.5 million kilowatts. The required air flow during operation is as high as 3,964,321 cubic meters per second, and the required spray water volume is 28.3 cubic meters per second.

The disadvantage of this kind of airflow power generation tower is that it can only be built in areas with sufficient water and sunshine, and it takes a lot of electricity to pump a lot of water, which increases the cost of power generation, and when using seawater, the treatment of the salt contained in it is also a big problem. problem.

Detailed ways

As we all know, gas always flows from high pressure space to low pressure space, and from low pressure space to vacuum space. And when the gas flows from the high-pressure space to the low-pressure space or from the low-pressure space to the vacuum space, the greater the pressure difference, the faster the gas flow, and the greater the power of the gas flow. In addition, in the case of the same gas flow rate, the smaller the cross-sectional area of the gas flow channel of the pipeline it passes through, the faster the gas flow rate.

The current thermal power generation system utilizes the above principles to generate electricity. Take the work of a 125,000-kilowatt steam turbine generator set as an example: it uses fuel to turn water into high-temperature and high-pressure steam in a high-pressure boiler, and the steam is drawn out through two metal pipes with an inner diameter of 0.5 meters thick connected to the high-pressure boiler. And the expansion nozzle is used to continuously impact the steam with a kinetic energy of 600-700 m/s and a steam flow rate of 400 tons per hour to the steam turbine to make it rotate rapidly and drive a 125,000-kilowatt generator to generate electricity continuously.

The principle of the wind power generation system of the present invention is similar thereto. Fig. 1 is a longitudinal sectional view of a preferred embodiment of the wind power generation system of the present invention. Fig. 2 is a top view of said preferred embodiment of the wind power generation system of the present invention. As can be seen from the figure, the wind power generation system of the present invention includes: a wind tower 1, which is a hollow cylinder for forming a low-pressure space, the diameter of the bottom of the wind tower can be greater than or equal to its top diameter, and the wind tower 1 The lower part of the wind tower is provided with 10 heat injection holes 12 that run through the wind tower wall, and 10 jets 18 corresponding to each heat injection hole are arranged outside the wind tower to inject flames into the wind tower 1 through the heat injection holes 12. , hot air or hot water; the lower part of the wind tower 1 is also provided with 10 air inlets 2 arranged separately from the heat injection holes 12, and an air inlet pipe 5 is stretched out from each air inlet 2, and the turbine 4 is placed In the intake duct 5, each turbine is coaxially connected with a generator 15 located outside the intake duct.

The operation principle of the wind power generation system of the present invention is introduced as follows: Utilize the gas or liquid fuels arranged in the fuel depot outside the wind tower, such as hydrogen, natural gas, coal gas, liquefied petroleum gas, petroleum and other fuels or use geothermal gas, geothermal Hot water, water vapor, waste hot water discharged from industry, waste heat gas (waste heat), hot air obtained by using electric energy or solar energy, hot water and other available high and low temperature heat energy are injected into the hot gas tank installed outside the wind tower, hot water In the tank or hot water pool, pump the fuel, hot gas or hot water to the jet machine 18 through the pipeline, and use the jet machine 18 to spray the flame, hot gas or hot water into the wind tower through the spray hole 12, so that the heat released Heat the air in the lower part of the wind tower 1, make the heated air flow from the lower part of the wind tower 1 to the upper part to form hot air, and reduce the air pressure inside the wind tower 1 to form a low-pressure space inside the wind tower, and at the same time make the wind tower 1 A certain temperature difference and convection are formed between the inside and outside air, so that the unheated air outside the wind tower 1 with higher air pressure flows to the inside of the wind tower through the air inlet pipe 5, forming cold wind in the air inlet pipe 5.

The hot air in the wind tower 1 is continuously discharged into the atmosphere through the hot air outlet on the top of the wind tower 1, and the air outside the wind tower 1 is continuously injected into the wind tower 1 through the air inlet pipe 5, thereby forming a certain flow rate in the air inlet pipe 5. airflow. When the speed of the airflow reaches a predetermined value, the turbine 4 located in the intake pipe 5 can be driven to rotate at a certain speed, thereby driving the generator 15 coaxially connected with it to generate electricity.

As long as the height and diameter of the wind tower 1 and the diameter of the intake pipe 5 are properly set as required, and the amount of heat injected by the jet machine 18 is properly controlled, the speed of the airflow in the intake pipe 5 can be controlled, thereby controlling the turbine generator 15. of power generation.

The wind power generation system in this embodiment of the present invention may also include: a safety pipe 3 correspondingly connected to each air inlet pipe 5, the first end of which is connected to the air inlet pipe 5, and the second end faces directly upward or obliquely upward, and its length and direction sufficient to ensure the safety of persons or animals in the vicinity of the second end. A filter 8 is arranged at the port of the second end of the safety pipe 3 for filtering out foreign matter in the air, so as to ensure the cleanness of the airflow passing through the turbine 4 . On the side opposite to the air intake pipe 5 at the first end of the safety pipe 3, an opening 9 may be provided for draining water injected into the safety pipe 3 due to rain.

As shown in Figure 2, each air inlet pipe 5 of the wind power generation system of this embodiment is divided into a first branch pipe 51 and a second branch pipe 52 at a certain distance outside the wind tower 1, and in the first branch pipe 51 and the second branch pipe 52 One turbine 4 is placed respectively, and the first branch pipe 51 and the second branch pipe 52 ′ of the adjacent intake pipe 5 ′ on one side are merged together again, and are connected with the safety pipe 3 . The second branch pipe 52 is merged with the first branch pipe 51" of the intake pipe 5" on the other side, and is connected with the safety pipe 3'. Filters 8 are respectively set at the ports at the end. The rest of the intake pipes are also arranged in this way. The advantage of this arrangement is that the number of intake pipes can be reduced when the number of generators is fixed. At the same time, in one of them When one or several turbines or generators need to be repaired or overhauled, the operation of the rest of the units will not be affected.

As shown in Figure 2, the air inlet pipes 5, 5', 5 ", ... of the wind power generation system of the present embodiment can be divided into a diverging nozzle 6a and a straight pipe 6b, and the diverging nozzle 6a is formed from the inlet pipe 5 One end connected with the safety pipe 3 to the inlet pipe 5 near the turbine 4 is a diverging nozzle structure, that is, the cross-sectional area of the air flow channel gradually decreases as it is far away from the safety pipe 3, and the straight pipe 6b flows from the inlet pipe 5 to the turbine 4. From the side near the safety pipe 3 to the air inlet 2 of the wind tower, it is a straight pipe structure along its entire length, and the cross-sectional area of its airflow passage is larger than that of the airflow passage at the junction of the divergent nozzle 6a and the straight pipe 6b. Area. The turbine 4 is placed in the straight pipe 6b, and is close to the connection with the divergent nozzle 6a. The air inlet pipe 5 of the wind power generation system of the present invention can be arranged on the ground plane according to actual needs, and can also be arranged on the ground plane or partly below the ground plane. Set below ground level.

The wind power generation system of the present invention also includes a movable gate 10 arranged in the air inlet pipe 5 and located on the side of the turbine 4 close to the air inlet 2 . In the first embodiment of the present invention, as shown in Figures 1 and 2, the movable gate 10 is arranged in the straight pipe 6b, and is located on the side of the turbine 4 away from the divergent nozzle 6a, when the turbine 4 or generator needs to be 15 When overhauling or repairing, the movable gate 10 can be closed to ensure the safety of the staff and not affect the normal operation of other turbines and generators

The wind power generation system of the present invention arranged in such a structure can be built in different scales according to the size of the required generating capacity and the amount of invested capital. Described below is a specific example of implementing the present invention.

The wind tower 1 is a hollow conical body structure with a height of 600 meters, a bottom diameter of 60 meters, and a top diameter of 40 meters. The bottom wall thickness of the wind tower 1 can be 1 to 2 meters, preferably 1.5 meters. The wall thickness can be 0.3-0.4 meters, preferably 0.35 meters. Below the ground level at the bottom of the wind tower, 10 door-shaped air inlets 2 are arranged equidistantly along the circumference, each of which is 8 meters high and 5 meters wide, and the top of the air inlets 2 is 2 meters lower than the ground level. The purpose of the air inlet 2 being designed as a door is to ensure the firmness of the bottom of the wind tower. An air intake pipe 5 is arranged corresponding to each air inlet 2 , and a turbine 4 is respectively arranged in the first branch pipe 51 and the second branch pipe 52 of the air inlet pipe 5 . The safety pipe 3 has an outer diameter of 26 meters and a depth of 10 meters at the part below ground level.

When the heat released by the flame, hot air or hot water sprayed into the lower part of the inner space of the wind tower reaches 61.388 kcal/s, the air in the wind tower can be continuously heated, so that the temperature difference between the inside and outside of the wind tower reaches 7°C, which is higher than the wind tower The hot air at 7°C outside the air can rise at a speed of 10 m/s in the 600-meter-high wind tower, and the speed is 36 km/h, which is equivalent to a strong wind of level 5. The rising flow rate of the hot air in the tower is 28260 m3/ seconds (the thermal expansion of air is ignored). Simultaneously, the air flow entering the wind tower through the air intake pipe 5 from the outside of the wind tower is also 28260 m/s, and the air velocity at the first port of the air intake pipe is 20.16 km/h, which is equivalent to a wind of grade 4. When the air flow of such a wind speed passes through the divergent nozzle structure of the air intake pipe 5 (the cross-sectional area of the airflow channel at the entrance of each divergent nozzle 6a is 20 square meters, 20 divergent nozzles in total), the "narrow tube" effect is produced , so that the flow velocity flowing through the inlet of the expansion nozzle 6a is 7 times the rising velocity of the hot air in the wind tower, up to 70 m/s. Again because the inner diameter of divergent nozzle 6a dwindles gradually, so the flow velocity of air flow in the more and more narrow passage is faster and faster, when flowing through the small diameter of the junction of divergent nozzle 6a and straight pipe 6b (each small When the cross-sectional area of the airflow channel at the aperture is 2 square meters, there are 20 in total), its flow velocity is 70.65 times of the rising velocity of the hot air flow inside the wind tower, which is 706.5 m/s, so that the weight can be reduced in a long time of 1 second. The cold air flow with a weight of 1827 kg and a flow rate of 1413 m3/s passes through the small-diameter end at high speed and sprays into the straight pipe 6b, so that the turbine 4 located in the straight pipe 6b rotates at a high speed, and can drive 20 turbines of 600,000 kilowatts to generate electricity unit.

The wind power generation system of the present invention may also include water spray holes 11 arranged on one or more air intake pipes near the wind tower side and a high-pressure water spray gun (not shown) located outside the wind tower. When a large amount of flame, hot water or hot gas is sprayed to the lower part of the space in the wind tower by the jet machine 18, the air in the wind tower is heated and rises, causing the cold air outside the wind tower to enter the inside of the wind tower at a high speed through the intake pipe 5 , using a high-pressure water spray gun to spray water into the intake pipe 5 at high speed through the water spray holes 11, and the high-pressure water column sprayed into the intake pipe 5 has a very strong friction with the air flow passing through the intake pipe 5 at high speed, thereby It releases powerful energy, which separates the hydrogen atoms and oxygen atoms in the water molecules to generate oxygen and hydrogen, and generates a large amount of electric charge. Under the action of electric charge, the mixture of hydrogen and oxygen burns rapidly, and a large amount of heat generated by combustion is sent to the inside of the wind tower along with the high-speed air flow, thereby increasing the heat sent to the inside of the wind tower. When the temperature difference between the inside and outside of the wind tower reaches 7°C and it runs stably for a period of time, it can partially or completely stop spraying flames, hot air or hot water into the wind tower. When the water spray speed and water spray volume of the high-pressure water spray gun are appropriate, even if the spraying of flames, hot air or hot water to the inside of the wind tower is completely stopped, the heat required for heating the air inside the wind tower can be maintained, thereby maintaining the air intake. The air velocity in the tube is at a certain level. By adjusting the water spray volume and water spray speed of the high-pressure water spray gun, the air velocity in the intake pipe can be adjusted to achieve the purpose of regulating the power generation.

The second embodiment of the present invention will be described below. For simplicity, only the parts of the second embodiment that are different from those of the first embodiment are introduced, and the parts that are the same as those of the first embodiment are not repeated here.

Fig. 3 shows a longitudinal sectional view of a second preferred embodiment of the wind power generation system of the present invention. Fig. 4 shows a top view of a second preferred embodiment of the wind power generation system of the present invention. As can be seen from Fig. 3 and Fig. 4, the only difference between the wind power generation system of the second embodiment of the present invention and the first embodiment is that a resistance wire 7 is arranged at the bottom of the inner space of the wind tower, and the two ends of the resistance wire 7 The terminal can be connected to the mains through a switch, which is used to heat the air inside the wind tower by using the heat released by the resistance wire after power-on. Therefore, the heat spray hole, spray machine, water spray hole and high-pressure water spray gun adopted in the first embodiment are no longer needed.

The resistance wire 7 can be arranged in a spiral coil shape or a net shape, as long as the heat released by it is enough to heat the air inside the wind tower to the required temperature after being energized.

The above describes the wind power generation system of the present invention by way of embodiments. But the present invention is not limited to the mode described in the embodiment, for example the height and the diameter of the wind tower of the wind power generation system of the present invention are not limited to the above-mentioned data, the height of the wind tower can be designed as 800 meters, 1000 meters according to actual needs , 1200 meters or more, etc., can also be designed as 500 meters, 300 meters, 100 meters or less, etc., as long as the diameter and thickness and the design of the intake pipe are changed accordingly.

The temperature difference between the airflow inside and outside the wind tower is not limited to 7°C, and this value can be set according to the amount of power generation required and the conditions of the heat source. However, the larger the temperature difference, the faster the airflow in the intake pipe, and the more electricity the turbine generator will generate, otherwise, the less electricity the turbine generator will generate.

The airflow channel in the intake pipe can also adopt other shapes, as long as the schemes whose function is to control the airflow velocity passing through it all fall within the protection scope of the present invention.

According to the thermal power generation system of the present invention, the number of injectors used may also be one or more than the number of heat injection holes. The heat injection pipe of the heat injection hole sprays into the wind tower.

The intake pipe can also be directly installed with a filter at its entrance without being divided into the first branch pipe and the second branch pipe, or if the intake pipe is divided into two or more branch pipes, a safety pipe can be installed directly at the entrance of each branch pipe. or filter.

Industrial applicability

Because the wind power generation system of the present invention makes full use of the air pressure difference between the airflow inside and outside the wind tower and adopts two parts of the expansion nozzle type and the straight pipe in the design of the intake pipe, it can efficiently utilize high and low temperature heat energy, thereby greatly reducing the cost of power generation. Reduced, and its wind power is strong and stable, suitable for power generation systems of various capacities. In addition, the heat source used by the wind power generation system of the present invention is basically unlimited, so that industrial waste heat and other high and low temperature heat energy can be fully utilized to generate electricity.

Compared with the prior art, the wind power generation system of the present invention can save a large amount of water and the electricity used for pumping water, and save the trouble of dealing with sea salt. The scale of the wind tower is small, and its applicable geographical range is wider.
