Description

Air temperature difference power generation system

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an air temperature difference power generation system, and more particularly to an air temperature difference power generation system that uses a temperature difference between hot and cold air formed by heat and air to generate electricity by convection. Background technique

At present, the methods used for large-scale power generation mainly include thermal power generation, hydroelectric power generation, and nuclear power. The disadvantages are high cost, low efficiency, and serious environmental pollution. The methods used for small-scale power generation mainly include solar power generation, natural wind power generation, tidal power generation, and geothermal power generation. The problem is that the power generation is small and unstable, and the need for increasing power generation cannot be met.

Beijing "Solar" editorial published in the "Solar" magazine in 1983, No. 2, page 12 (Author: Wenjun Zhou) reported a design by Dr. Philip Carlson solar chimney power tower. The principle is that a pump is used to pump seawater along the pipeline to the top of the tower, and the water is sprayed by a spray device, and the water mist is quickly evaporated in the dry hot air to cool and humidify the surrounding air, thereby increasing the density. The cooled overhead air sinks along the circular tower cavity, creating a continuous downward flow. Due to the high tower height, the cylindrical tower has a diversion effect on the airflow, which speeds up the airflow. In the lower part of the tower, the tower cavity is partitioned into a circular passage by a large airflow hood, the cross section of which is rapidly reduced, and the velocity of the air flowing therethrough is further increased, thereby generating strong wind. In the annular passage, 10 turbine generator sets are evenly arranged in the circumferential direction, which are rotated and forwarded by the high air flow. The tower has a height of 2,400 meters, a top diameter of 274 meters and a maximum output of 2.5 million kilowatts. The required air flow during operation is up to 3,964,321 cubic meters per second and the required spray volume is 28.3 cubic meters per second.

The disadvantage of this type of gas power generation tower is that it can only be built in water and sunny areas. It takes a lot of electricity to extract a large amount of water, which increases the cost of power generation. When seawater is used, the treatment of salt is also a big problem.

China Tianjin, "Science and Life" editorial editor, Tianjin Science and Technology Publishing House of the journal "Science and Life" on page 51 4 15 July 1987 (Author: Wei Minjie) reported a of Dr. Yan Juansen Design and manufacture of a tornado fan model (using natural wind). The principle is that the towers are surrounded by small windows that are separated by slats. The small windows facing the wind are closed, and the small windows of the lee are closed. After the wind blows into the tower, it begins to rotate, forming a small tornado. Below the small tornado is a cyclone-driven impeller at the bottom of the tower. When the tornado draws the air below it into the tower, it turns the impeller to rotate the generator to generate electricity. Such a tornado fan is 10 times more powerful than a windmill with the same size of a pneumatic impeller. Another scientist proposed the idea of a solar tornado power station. The principle is quite simple: a large-area fully transparent circular plastic film ceiling is laid, and the plastic shed is gradually raised from the periphery to the center, connecting the central chimney tower. The air between the plastic shed and the ground, which is sun-heated to 20 ~ 50 °C, flows to the tubular tower, and then rises along the tower, driving the air impeller in the tower. Even if there is no wind outside, the airflow velocity in the tower can reach 60 meters per second, which is the tornado wind speed. The power of this power plant can reach 700,000 to 1 million kilowatts.

The disadvantage of these two tornado towers is that they can only be built in natural winds and sunny areas, and are affected by terrain and climate. Sometimes they are not. They are large and small, very unstable, which seriously affects normal power generation and is not easy. control.

The State Intellectual Property Office of the People's Republic of China announced on May 14, 2003 a "Wind Power System", International Publication Date: December 11, 1997 (PCT International Invention Patent). On June 1, 2005, an "artificial tornado power generation system" was announced. The two power generation principles are that the fuel or other heat source is injected into the air in the heating tower of the wind tower, so that the cold and hot air inside and outside the wind tower form a temperature difference and a pressure difference, and a convection motion of the hot and cold air inside and outside the air inlet pipe communicating with the wind tower, and The turbine generator set in the intake pipe is used to generate electricity when the cold airflow flows through the intake pipe. The disadvantage of the two power generation systems is that a large amount of fuel must be consumed to form a temperature difference and a pressure difference between the wind tower and the intake pipe, as well as convection of the hot and cold air, so that the cold air flow generates power when propelling through the intake pipe to push the intake pipe. Turbine generators generate electricity. Another disadvantage is that there is no insulation effect for the single-layer wind tower structure.

On September 20, 2006, the State Intellectual Property Office of the People's Republic of China published a “Artificial Tornado Air Temperature Difference Power Generation System”. The principle of power generation is to use fuel or other heat source to inject the air in the heating tower of the wind tower, so that the temperature difference and the air pressure difference between the inside and outside of the wind tower and the convection movement of the hot and cold air in the air tower and the connected intake pipe are When the cold airflow flows through the intake pipe at a high speed, high-speed friction occurs with the inner wall of the intake pipe to generate heat, so that the intake pipe becomes a heat pipe, so that the cold air flow absorbs heat, and the hot air flows into the wind tower to rotate upward, so that the wind tower forms a low-pressure space, thereby saving a large amount of fuel. And using the cold airflow to flow through the intake pipe to drive the turbine generator set in the intake pipe to generate electricity.

The disadvantage is that since the inner diameter of the single intake pipe structure is large and the area is small (relative to the area of the plurality of intake pipes), the frictional contact surface with the inner wall of the single intake pipe is small when the cold air current flows through the single intake pipe at a high speed. Therefore, the cold air flow generates less heat when it is subjected to high-speed friction with the inner wall of the single intake pipe, so that the cold air flows through the single intake pipe and absorbs less heat and the temperature is low, but only a part of the fuel is saved. It takes a lot of fuel. Another disadvantage is that the single intake pipe does not have a valve or gate to control the flow rate and temperature of the air flow, but the valve or the gate is additionally set on the cold air pipe for adjustment. It is not appropriate, and the valve or gate should be placed on the intake pipe. It can conveniently control the flow velocity of the airflow when flowing through the intake pipe and the frictional strength with the inner wall of the intake pipe, as well as the heat and temperature difference.

The common shortcoming of the above-mentioned technical solutions for generating electricity by various wind towers is that the direct flow of the airflow directly into the wind tower impacts the wind tower wall, so that the wind tower wall is quickly damaged, and the safety of the wind tower is not ensured. Another common shortcoming is the failure to use a heat pipe or solar heat sink to extract a geothermal heat source or a solar heat source or a heat source such as hot water or hot gas. Summary of the invention

The air temperature difference power generation system of the present invention is a natural law that utilizes a heat pipe or a solar heat absorbing device to extract a geothermal heat source or a heat source such as hot water or hot gas or solar energy, and a small amount of fuel or other heat source and root to rub each other to generate heat, and Introducing a heat source into the bottom of the wind tower or decelerating the inside of the intake pipe to form a low-pressure space inside the wind tower or inside the deceleration intake pipe to achieve the purpose of generating air temperature difference power, that is, using various heat sources to spray into the lower part of the wind tower or Decelerate the inside of the intake pipe to make the wind tower and its connection The air inside and outside the air intake pipe (wind tunnel) forms the temperature difference between the cold and hot air and the air pressure difference and convection, so that the cold air is used to push the turbine in the intake pipe to drive the generator to generate electricity when the air is passed through the intake pipe at a high speed. High-speed friction occurs through the inner wall of one or more or one porous or multiple porous intake pipes. The heat can make the intake pipe a heat pipe. The function of providing multiple or one porous or multiple porous intake pipe structures is to not increase the intake pipe. The cross-sectional area increases the frictional area of the cold airflow when flowing through the intake pipe at a high speed, so that more heat is generated in the intake pipe, and the temperature of the cold airflow becomes a hot air flow, so that the cold air absorbs a large amount of heat energy. After becoming hot air, it flows into the wind tower or decelerates into the intake pipe. When the cold air in the intake pipe becomes hot air flowing into the wind tower or decelerating the intake pipe, the temperature difference between the inside and outside of the wind tower or the inside and outside of the deceleration intake pipe is gradually increased. The fuel or other heat source can be gradually reduced until the temperature difference and the air pressure difference between the cold and hot air inside and outside the wind tower or inside and outside the deceleration intake pipe When the speed reaches the required power value, or a small amount of fuel to the hot heat source heat or solar heat or hot water or other hot gas (high temperature heat source solar heat may be obtained by focusing technique). When the wind tower or the deceleration intake pipe and the intake pipe are installed, even if the wind tower is not artificially introduced into the wind tower or any heat source in the intake pipe is decelerated, the air inside and outside the wind tower or the air inside and outside the deceleration intake pipe should have a natural temperature difference c or more. (As we all know, there is a certain temperature difference between the air inside and outside any building), that is, the temperature inside the wind tower or in the deceleration intake pipe is higher than the temperature outside the wind tower or outside the deceleration intake pipe, so that the airflow flows through A certain amount of power is generated in the intake pipe, and the structural design of the present invention makes full use of the power caused by the natural phenomenon of the temperature difference, thereby saving a large amount of heat source.

It is well known that gas always flows from a high pressure space to a low pressure space, from a low pressure space to a vacuum space. 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 flows, and the greater the power of the gas flow. In addition, in the case where the gas flow rate is the same, the smaller the cross-sectional area of the gas flow passage through which the pipe passes, the faster the flow rate of the gas.

The current thermal power generation system uses the principles described above to generate electricity. Take the working principle of a 125,000-kilowatt steam turbine generator set as an example: It uses steam to turn water into high-temperature and high-pressure steam in a high-pressure boiler, and steam is passed through two metal pipes with an inner diameter of 0.5 m connected to a high-pressure boiler. Leading, the kinetic energy is 600 meters to 700 meters / sec, the steam flow of 400 tons / hour of steam continuously impacts the steam turbine, which makes it rotate rapidly and drives the 125,000 kW generator to continuously generate electricity.

The cold air is subjected to high-speed friction with one or more or one of the porous or a plurality of porous intake pipes 8 and the inner wall of the intake pipe 15 at a high speed through one or more or one of the porous or a plurality of porous intake pipes 8 and the intake pipe 15. The temperature rise of the inner wall generates a large amount of heat to make the intake pipe 8 and the intake pipe 15 a heat pipe, so that the cold air flowing through one or more or one of the porous or a plurality of porous intake pipes 8 and the intake pipe 15 absorbs a large amount of heat and is heated into Hot air flows into the interior of the wind tower 1 or 12 or decelerates the inside of the air intake pipe 22 from the high-speed air inlet 3, and pushes the turbine 7 inside the intake pipe 15 to rotate coaxially under the strong potential energy generated by the high-speed airflow. The generator 13 is rapidly decelerated after power generation, and rises inside the wind tower 1 or 12, or rapidly decelerates in the deceleration intake pipe 22, and then slowly flows into the interior of the wind tower 1 or 12 to rise, so that the wind tower 1 or 12 is internally decelerated. The interior of the trachea 22 collectively forms a low pressure space. When the hot air flows into the interior of the wind tower 1 or 12 or decelerates the inside of the intake pipe, the temperature of the hot air inside the wind tower 1 or 12 or inside the deceleration intake pipe is increased and the inside and outside of the wind tower 1 or 12 and the deceleration intake pipe are decelerated. The temperature difference between the inside and outside of the hot and cold air and the air pressure difference and convection increase. Therefore, in order to maintain the temperature difference and the air pressure difference and the convection speed of the hot and cold air inside and outside the wind tower 1 or 12 and decelerate the intake pipe, the required power value and stability are maintained. There is a need to reduce fuel or other heat sources injected into the interior of the tower 1 or 12 or decelerating the interior of the intake duct 22. If cold air flows at high speed One or more or one porous or a plurality of porous intake pipes 8 and intake pipes 15 are subjected to high-speed friction with one or more or one porous or a plurality of porous intake pipes 8 and the inner wall of the intake pipe 15 to generate a large amount of heat to heat the cold air.

The outer layer is formed to create a space between the inner and outer tower walls, which can serve to keep warm, reduce noise and stabilize the wind tower. The wind tower structure of the present invention may be a single layer or a multilayer structure, forming a space between the walls of the plurality of layers. 10-20 straight or oblique gate-shaped air inlets 3 are arranged equidistantly in the circumferential direction below the bottom plane of the wind tower, each of which has a cross-sectional area of 2 m ² or a width of 3 to 5 m and a height of 10-20. m, 30~ cross-sectional area: 100 m ² (provided in the peripheral wall of the wind tower deceleration column wall after the intake pipe 22 intake port 3 of the cross-sectional area), the top of the intake port 3 is 2 meters below ground level. With each The intake port 3 is provided with an intake pipe 15 disposed in the wind tower, a turbine and a coaxially connected generator 13 are disposed in the intake pipe 15, or a deceleration is provided at the bottom wall of the wind tower 1 or 12 and the periphery of the intake port 3 The intake pipe 22 has a width of 15 to 20 meters, a height of 10 to 20 meters, and a wall thickness of 1 to 2 meters. The outer wall around the deceleration intake pipe 22 is provided with 10 to 20 air inlets 3 at an equal distance, and the height is 3 Meters, 3 meters wide or 2 square meters for each air inlet 3, the top of the air inlet 3 is 2 meters below the ground plane, or above the ground level, each air inlet 3 corresponds to After one or more or one porous or multiple porous intake pipes 15 are extended obliquely or straightly outward, one or more intake pipes 15 are extended outwardly or one or more intake pipes 15 are branched, at each One or more turbines 7 are disposed in the one or more intake pipes 15, and each of the turbines 7 is coaxially connected with a generator 13 located outside the intake pipe 15. The structure of the intake pipe 15 may be a circular shape or a square shape or the like. The size, the length, and the number can be designed as needed. The inner diameter of the safety tube 10 communicating with the intake pipe 15 is 8-12. The wall thickness is 0.3 - 0.5 m, the depth below the ground plane is 8 - 10 m, the height above the ground is 10-20 m, and the intake pipe 15 communicating with each safety pipe 10 and each turbine 7 The segments can of course also be provided as one or more or one porous or a plurality of porous intake pipes 15.

When the heat released from the lower part of the inner space of the wind tower or the heat source inside the deceleration intake pipe continuously reaches 61,388 kcal / sec, the air in the wind tower or in the deceleration intake pipe can be continuously heated to make the wind tower inside or outside or And the temperature difference between the hot and cold air inside and outside the deceleration intake pipe reaches 7. C, higher than the air outside the wind tower 7. The hot air of C rises at a speed of 10 m/s in a 600-meter-high wind tower, and when it is 36 km/h, it is equivalent to a 5-level wind. The rising flow of hot air in the tower is 28,260 ^m3 / s (the thermal expansion of air does not count) ). At the same time, the flow of cold air flowing from the outside of the wind tower through the intake pipe 8 and the intake pipe 15 into the wind tower 1 or in the deceleration intake pipe 22 is also 28260 m ³ /s, and the air flow velocity at the first port of the safety pipe 10 It is 36 km/h, which is equivalent to 5 winds. When the cold air flow of such a wind speed passes through the structure of the expansion nozzle type intake pipe 8 of the intake pipe (the cross-sectional area of the air flow passage at the entrance of each intake pipe 8 is 20 square meters, 20 intake pipes 8 and 20 safety pipes 10, each of which has an inner diameter of 8 m), and the flow rate of cold air flowing through the inlet of the intake pipe 8 is 7.065 times the rising speed of the hot air in the wind tower 1, up to 70.65 m/s. Since the inner diameter of the structure of the intake pipe 8 is gradually reduced, the flow rate of the air flow in the narrower and narrower passage is faster and faster, when passing through the small diameter of the intake pipe 8 or the air outlet of the straight pipe type intake pipe 15. (the cross-sectional area of each small-diameter or straight-tube intake pipe 15 is 2 square meters, a total of 20), resulting in a "stubbing effect" whose flow rate is 70.65 times the rate of rise of the hot air inside the wind tower 1, It is 706.5 m / sec, so that the weight is 36.54 ton / sec in a one second long time, and the cold air having a flow rate of 28, 260 m ³ / sec passes through the small diameter end of the 20 intake pipes 8 and is injected into the intake pipe 15 Inside, the turbine 7 in the intake pipe is impacted, and the turbine 7 located in the intake pipe 15 is rotated at a high speed to drive 20 sets of 600,000 kW turbine generators to continuously generate electricity. The cold air flow pushes the turbine 7 in the intake pipe 15 to drive the generator 13 to generate electricity, and then flows through the rear portion of the intake pipe 15 at a high speed (the total cross-sectional area of the intake pipe 15 is 40 square meters, and the flat area in the wind tower) When the ratio is: 70.65: 1 ), high-speed friction with one or more small-diameter or inner walls of a porous or a plurality of porous intake pipes 15 generates a large amount of heat to make the intake pipe 15 a heat pipe, making one or more or one porous Or the cold air flow in the plurality of porous intake pipes 15 absorbs heat energy to be heated into a hot air flow, with a potential energy of 706.5 m / sec, a weight of 36.54 ton / sec, a flow rate of 28260 m 3 / sec from the connected intake air The intake pipe 15 flowing into the inside of the wind tower at the mouth 3 pushes the turbine 7 in the intake pipe 15 to rotate, and the coaxially connected generator 13 generates power and then rapidly decelerates to eliminate the potential energy of the airflow, and then slowly rises in the wind tower, or at a high speed. The communicating air inlet 3 flows into the intake pipe 22 inside the wide deceleration intake port 22 to decelerate, and then slowly flows into the wind tower to rise, or flows from the connected intake port 3 into the deceleration intake pipe 22 at a high speed. In the intake pipe 15 The movable intake pipe 15 and then slow potential wind flow up a column, column 1 so that the internal air intake pipe and the reduction or

22 internal together form a low pressure space, when hot air flows into the interior of the wind tower 1 and slows down After the inside of the intake pipe 22, the temperature inside the wind tower 1 or the inside of the deceleration intake pipe 22 is increased, and the temperature difference and the air pressure difference and the convective movement speed of the inside and outside of the wind tower 1 or the inside and outside of the deceleration intake pipe 22 are increased. In order to keep the turbine 7 in the intake pipe 15 constantly stable, the temperature difference between the inside and outside of the wind tower 1 and the hot and cold air inside and outside the deceleration intake pipe 22 and the air pressure difference and the convection speed must be kept stable. Therefore, with the wind tower 1 The temperature inside or inside the deceleration intake pipe is gradually increased, and the fuel or other heat source injected into the interior of the wind tower or decelerating the inside of the intake pipe needs to be gradually reduced until the inside and outside of the wind tower 1 or the hot and cold air holding together with the inside and outside of the deceleration intake pipe 22 After the temperature difference and convection motion are required, a small amount of fuel or other heat source may be used. After a small amount of heat source is used, the temperature difference and the air pressure difference between the inside and outside of the wind tower 1 and the hot and cold air inside and outside the deceleration intake pipe 22 and the convection motion are still in stable operation, because The wind tower has a certain height and volume. The hot air discharged from the top of the wind tower per second is only one-60th of the total amount of hot air in the wind tower 1, and every second. The flow of hot air from the one or more or one or more porous or multiple porous intake pipes 15 into the wind tower 1 or supplemented in the deceleration intake pipe 22 is also one-60th of the total amount of hot air in the wind tower, and the discharged The flow of hot air flowing into the wind tower just coincides, and the inside of the wind tower 1 or the interior of the deceleration intake pipe always maintains a stable low-pressure space, that is, the temperature of the hot air in the wind tower 1 or the interior of the deceleration intake pipe 22 is always maintained. The temperature is higher than the outside air of the wind tower 1 by 7. The temperature difference of C, therefore, the temperature difference and the air pressure difference between the inside and outside of the wind tower 1 and the inside and outside of the deceleration intake pipe 22 and the convection movement can be maintained for a long time, and the flow of cold air flowing through the intake pipe 15 per second can be high speed. The rotation of the impact turbine 7 drives the generator 13 to generate electricity for a long period of time and output electric power. If the temperature inside the wind tower 1 or the interior of the deceleration intake pipe 22 is lowered or increased, the valve or gate provided at one or more or one of the porous or multiple porous intake pipes 15 may be appropriately opened or closed as needed or an appropriate amount or The fuel or other heat source is adjusted to be adjusted until the temperature common to the inside of the wind tower 1 or the interior of the deceleration intake pipe 22 reaches a desired stable temperature, and the temperature difference between the hot and cold air inside and outside the wind tower 1 or the inside and outside of the deceleration intake pipe 22 is reduced. And the pressure difference and the cyclic convection movement remain stable for a long time. Next, a second embodiment of the present invention will be described. For the sake of simplicity, only the portions of the second embodiment that are different from the first embodiment will be described, and the same portions as those of the first embodiment will not be described again.
