Description

Circulating water multistage power generation system

Technical Field

An electric energy production method belongs to the field of energy production and the hydroelectric industry.

Background

At present, the methods for producing electric energy on the earth mainly comprise:

1, thermal power generation. And A, generating power by burning coal. And B, generating power by using fuel oil (gasoline, diesel oil and kerosene). And C, generating power by using alcohol. And D, generating power by using garbage.

And 2, hydroelectric power generation.

And 3, solar power generation.

And 4, generating power by wind energy.

And 5, generating power by using nuclear energy.

6, generating electricity by using geothermal energy.

7, generating power by using methane.

And 8, generating power by tidal energy.

The thermal power pollutes the environment. Traditional hydropower has to be aided by natural and thick natural resources, and has ecological problems, safety problems, immigration problems and the like. The utilization of solar energy and wind energy can obtain the face color of the old fashioned grandpa. Nuclear energy has huge potential safety hazards, and the treatment of nuclear waste is difficult to properly solve. Exploitation of geothermal energy is also limited. The biogas has small generating capacity and is suitable for rural individuals or small-range power utilization. In summary, energy is an extremely important and demanding thing in the world. But the world has not solved this problem completely.

The traditional hydroelectric power generation utilizes the geographical conditions of rivers and reservoirs to generate driving force (converting potential energy into mechanical energy) when water in a high region flows to a low region, and pushes a water turbine to rotate, so that a generator is driven to generate power (converting mechanical energy into electric energy). The number of rivers and the number of positions where the dam can be built for power generation are just so on, and the demand of continuous development of human beings can not be met. More importantly, water is a source of life, and serious water shortage exists in many places. It is difficult to use water, even to eat water. How may water be used to generate electricity?

In addition, the water pumping energy storage power generation is characterized in that water at a low position is pumped to a high position for storage at a power utilization peak, and the water stored in a reservoir at the high position is used for power generation when the power utilization peak is reached.

The hydropower is limited by the district and the water quantity, so that the production of the hydropower is limited.

The inventor successfully solves the fundamental problem restricting the development of hydropower, and breaks through the bottleneck of hydroelectric power generation technically, methodically and on the overall solution. The invention creates a circulating water multistage power generation system.

Detailed description:

one, human beings have been over a hundred years old with hydroelectric power, but to date, all hydroelectric power plants have been single use hydroelectric power. Starting from my invention, mankind will create a new chapter of recycling circulating water for power generation.

How can the hydraulic power generation be recycled? The key point is to lift the tail water used for power generation to a high position. My invention is:

firstly, a huge rotating wheel is built by adopting a ferris wheel water lifting method like a ferris wheel in an amusement park, and dozens of uncovered water tanks are sequentially hung along the outer ring of the wheel. (see FIG. 1)

The radius of the rotating wheel (II) is the distance and height to be lifted, and the rotating wheel can be large or small and can be long or short. (see FIG. 1)

And (III) the volume of the water tank is required to be larger than the flow of the water turbine. The principle of fully meeting the requirement of the water quantity of the tail water in lifting and transporting is taken.

And (IV) the ferris water lifting wheel is arranged at a tail water outlet of the water turbine, the water tank automatically sinks when being filled with tail water, the water tank is sequentially filled with tail water, and the rotating wheel automatically rotates.

And (V) a plurality of drainage pipes are arranged at the lower part of the outer side of each water tank, so that the water tanks are continuously leaked. In the power generation process, tail water flows out continuously, the water tank on one side of the water receiving port is supplemented with the tail water continuously, and although the drain pipes on the lower part of the water tank are the same, the flow of the tail water is definitely much larger than that of water leakage. The water tank on one side of the water receiving opening is fully loaded, the water leakage of the water tank on the other side of the ferris wheel is reduced, the water tank rotates and rises continuously, when each water tank reaches the highest point, namely, the position is higher than the water level of the upper reservoir, the position is the upper water outlet, the water door on the outer side of the water tank is opened automatically, and the water in the water tank is discharged out and flows to the upper reservoir along the channel. (see FIG. 1)

And (VI) automatically closing the water door of the water tank after water is discharged. The water tank is still continuously rotated. The empty water tank after pouring water rotates downwards.

(VII) generally, the water receiving port of the ferris wheel is arranged at the 3 o 'clock position, and the 9 o' clock position is a balance point, but the water tank on the side of the 3 o 'clock is increasingly heavier as the water tank on the side of the 3 o' clock is continuously used for receiving water. The water tank on the side of the 9 o ' clock continuously leaks water, the water tank is lighter, so the water tank continues to run clockwise after passing through the 9 o ' clock position, and water is discharged when reaching the 12 o ' clock position. The empty water tank receives water at the 3 o' clock position. The ferris wheel rotates continuously, and the water tank continuously transports the water of the lower reservoir used for power generation to the upper reservoir. (see FIG. 1)

(eight) one or a plurality of traditional agricultural irrigation water wheels are installed, all the leaked water is lifted and transported from the bottommost layer to a lower reservoir communicated with a tail water outlet, the flow direction of the water in the reservoir is also a water tank on the ferris wheel, then the water reaches an upper reservoir and flows to a water turbine through a water guide pipe.

The basic structure of the waterwheel is as follows: a rim plate setting that has the blade is at the delivery port of tail water, and the tail water constantly strikes the blade, drives the rim plate rotation, and the rim plate drives the waterwheel, and little water tank on the waterwheel is with all transport down in the cistern of leaking a case one box of bottommost layer. (see FIG. 3)

2, if the water leakage of the bottom layer is too much and the transport capacity of the waterwheel is not enough, the water leakage of the bottom layer can be increased by arranging a small ferris wheel, the residual water leakage can not be too much, and the agricultural irrigation waterwheel can be completely and thoroughly transported.

3, the lengths of the water leakage pipes below the water tank are the same, so that water leakage collecting grooves can be arranged on two sides of the water tank of the ferris wheel, and water leakage at a position more than 9 o' clock can flow back to the lower reservoir through the aqueducts. Water leakage at the 3 o 'clock position and below the 9 o' clock position is solved by the waterwheel. (see FIG. 4)

(ninth), if one ferris wheel can not lift water, the transportation of tail water can not be met, and then two ferris wheels are used for lifting water. If two parts are still not enough, three ferris wheels are used for lifting water, and the rest can be done in the same way, no matter how many ferris wheels are used, the tail water must be completely and thoroughly lifted to the upper reservoir. Generally, how much water is taken in will result in how much water is taken out.

Thirdly, the diameter of the diversion conduit of the three gorges hydropower station is 12.8 meters, the flow rate is 1020 cubic meters per second, and if only one ferris wheel is used, a 1100-ton water tank needs to be built, which is too large and difficult to master. Can be disassembled, adopts a 21 ton water tank, and is provided with 50 ferris wheels for lifting water at the same time. 70 ten thousand KW, two, one arrow two carves, that is 140 ten thousand KW, overlap and install 10 hydraulic turbines and generate electricity at the same time, that is 1400 ten thousand KW, install 20 hydraulic turbine sets, just so can generate electricity 2800 ten thousand KW. This is also simply a "string" of units that generate 20 electricity. This has reached the world's power station overwhelming. Of course, the calculation is carried out according to the data of the three gorges power station, and in the implementation process, the calculation can be completely freely created. The conditions of each power station are different, and each power station has various conditions and resources, and particularly, the circulating water multistage power generation system has unique advantages, unique technologies, unique methods, unique conditions, unique resources, unique efficiency and unique benefits.

Fourthly, the ferris wheel is also a huge water turbine which can not only lift water but also generate electricity. One or more generators are respectively arranged on two sides of the round mandrel of the ferris wheel.

And fifthly, one or more generators are respectively arranged on both sides of all the water turbines in the system. Thus, the power is increased by one time or even several times compared with the traditional hydroelectric generating set. This is a lateral superposition. The method is called 'one-arrow double-carving electricity generation method' or 'one-round multiple machines'. (see FIG. 2)

Sixth, the traditional hydroelectric power generation usually utilizes water resources at one time, invests huge capital, constructs huge dams, allows a lot of people to move, influences ecology and environment, has high economic cost and social cost, and is finished only by allowing water to pass through a water turbine. This is too pity. Too regret. Therefore, the circulating water multistage power generation system is invented and can be commonly called as a mutton string type power generation method or a multistage superposition power generation method. (see FIG. 2)

Each penstock or conduit (with a large or small diameter and a large or small water quantity) is arranged according to a certain fall, such as 5 meters, 10 meters to 100 meters, or larger or smaller. At certain angles, such as 90 degrees, vertical drop, absolute free fall, theoretically should be the most hydraulic. But which angle is the best angle for hydroelectric power generation, can obtain the maximum water power, can obtain the highest utilization rate of water resources, and can exert the utilization efficiency of water power to the utmost? Can be verified through practice. Generally, the smaller the angle of the penstock or penstock with the surface of the water or ground, the less hydraulic power. Conversely, the closer to the perpendicular angle, the greater the hydraulic force. Therefore, when a circulating water multistage power generation system can be freely designed, for the combination of various elements and the selection and determination of various parameters, the maximization of hydraulic utilization rate, the maximization of water resource utilization rate, the maximization of efficiency, the maximization of benefit and the minimization of cost should be pursued. I.e., spend the least money, use the least water, send the most electricity.

And (II) a certain water head is realized through a certain fall below each water conduit, after the designed flow and hydraulic energy are reached, a plurality of water turbine generator sets are overlapped and installed, and are vertical or close to vertical, (the multi-stage water turbine generator sets are vertically arranged and installed, and may be optimally designed) without spacing distance or with a certain spacing distance, three, five, eight, ten and twenty or more water turbine generator sets can be continuously installed, and all the water turbine generator sets are of a one-arrow double-carving type. I.e. one-wheeled with double hair. Or a plurality of machines in one round. The hydraulic energy is fully utilized. In addition, the tail water from the previous water turbine falls vertically, the water head is still relatively large, and the lower water turbine generator sets are pushed in sequence, so that the problem is solved and the operation is feasible.

Seventhly, my multistage vertical waterwheel power generation system of circulating water of invention includes:

1, straight-through type. The water flow directly flows through the water turbine, and the water flow pushes the blades to drive the water turbine to rotate.

And 2, spiral type. The water flow rotates for a circle in the water turbine and then flows out from the tail water port.

And 3, straight plate type blades. The method is mainly used for the straight-through water turbine.

And 4, a spoon-type blade. The method is mainly used for the straight-through water turbine.

And 5, water tank type blades. The method is mainly used for the straight-through water turbine.

6, fan type blade. The method is mainly used for the spiral water turbine.

Eighthly, if a plurality of the water turbine generator sets which are installed in an overlapped mode are gathered together, a water and electricity magic cube is formed. For example, a mutton shashlik is ten double-generator sets, nine mutton shashliks are strung together, that is, ninety double-generator sets, and one hundred eighty generators. At present, the largest hydropower station in the world also has only thirty-two generators. The scale of the hydropower station can be changed into large or small, the construction place can be selected at will, and only enough water is needed. A circulating water multistage power generation system can be built near rivers, lakes, reservoirs and oceans. The whole rivers, lakes, reservoirs and oceans can be used as an upper reservoir. A plurality of water-electricity magic cubes can be built in the lower reaches of the Yangtze river, the lower reaches of the Zhujiang river and coastal areas, the power utilization in the east part can be completely met, the power can be transmitted to the middle part and the west part, and the power can be transmitted to the whole country. The surplus electricity can also be sold to foreign countries. For example, some inland countries, such as Mongolia and other countries, have difficulty in developing water and electricity, and can buy the electricity in China.

Ninth, the construction of the circulating water multistage power generation system should select an area with better geological conditions, and if the distance is too far away from rivers, lakes and reservoirs, the cost is increased, and if the distance is too close, the water seepage and collapse are prevented. Should take water in the deep water district, prevent the wearing and tearing of silt to equipment.

Tenth, the structure of the circulating water multistage power generation system can be open or closed.

Step steps can be built around the open structure, the transparent glass is installed at the top, the huge sky-rubbing water lifting wheel is high and erected in the underground water power station, the top of the sky-rubbing water lifting wheel exceeds the ground, water in one tank is poured out, and an artificial landscape containing waterfalls can be built in the upper water channel link. Transparent glass is completely tempered from the upper reservoir to the upper water diversion canal and then to the upper water diversion pipe, and clear water of the white flowers can be seen to flow downwards and directly impact the water turbine. The hydraulic generator rooms are arranged on one layer and one layer, 10 layers, 20 layers, 30 layers and 50 layers or even more, transparent floor glass windows are adopted in all the hydraulic generator rooms, and the whole power station comprises the interior of the machine rooms and can be seen at a glance.

2, the closed structure can adopt a frame type structure, for example, huge well-shaped reinforced concrete can be adopted to support the surrounding underground space.

Eleventh, the ferris wheel water lifting system can be designed differently according to the needs.

1, a huge ferris wheel can be built, and water is lifted to the ground in a one-stop mode.

2, also can be respectively at different levels, build several ferris wheels, carry water to the ground step by step.

And twelfth, the seawater containing salt has certain corrosiveness on equipment. The anti-corrosion experience of submarines and ships can be used for reference.

Thirteen, the group type circulating hydraulic multistage power stations can be arranged like magic cubes. Can also be arranged like a necklace and can be called as a bright pearl necklace. Or arranged in a line along rivers, lakes and reservoirs and the shore of the ocean, and can be called 'a string of bright pearls'.

Fourteen, in principle, a circulating water multi-stage power generation system, namely: a water diversion channel, a water diversion pipe, an upper reservoir, a lower reservoir, a water lifting system, a safety system and an automatic control system are built by a mutton shashlik hydro-generator group. (see FIG. 5)

Detailed Description

I believe that my inventive hydroelectric experts are clear at a glance. And a hydropower expert can design a specific circulating water multistage power station scheme according to actual needs and objective factors.

And secondly, even if a multi-stage water wheel power generation mode is not adopted, the automatic water lifting system can also be used as a circulating water power station according to the traditional hydroelectric mode and the traditional automatic water lifting mode.

And thirdly, the connection of each level of the multi-level hydroelectric generating set is important, the water outlet of the tail water of each water turbine needs to be tightened up, water is required to be introduced, water is required to be guided, water power is required to be concentrated, the water turbine needs to be specially developed again, and the multi-level hydroelectric generating set is suitable for the requirement of multi-level power generation.

And fourthly, enough water quantity, enough fall, enough verticality, enough pressure, enough weight, enough flow rate, enough flow, enough impact, enough water head, enough water power, enough water energy and enough electric energy are rushed forwards, and the potential is not blocked.

Fifthly, the spacing distance and the fall are properly adjusted according to actual conditions.

And sixthly, optimal combination, highest efficiency and optimal benefit are pursued.

Seventhly, a small-scale circulating water multistage power station can be built firstly. Experience is obtained, and the scale is gradually enlarged. When the conditions are mature, an ultra-large scale giant circulating water multistage power generation system is built.

Eight, I think that the straight-through turbine is more suitable for the multistage vertical power generation of circulating water. The spiral type consumes more water power. Resulting in forced increase of the separation distance, enlarging the drop height, and thus increasing the new hydraulic power. But the propulsion generated by the helical turbine may be greater and more stable. The spiral type may be more suitable for the traditional disposable hydroelectric mode.
