Description

Technical Field

[0001] The present invention relates to the technical field of thermal power plant power generation, and specifically to an optimized control device for efficient and energy-saving thermal power plant power generation production. Background Art

[0002] Thermal power plant power generation uses combustibles (such as coal) as fuel to produce electric energy. It heats water to generate steam when the fuel burns, converts the chemical energy of the fuel into heat energy, the steam pressure drives the steam turbine to rotate, converts heat energy into mechanical energy, and then the steam turbine drives the generator to rotate, converting mechanical energy into electric energy. The prime mover is usually a steam engine or a gas turbine. In some smaller power stations, an internal combustion engine may also be used. They all generate electricity by using high-temperature and high-pressure steam or gas passing through a turbine to become low-pressure air or condensed water.

[0003] In the prior art, there are still many drawbacks.

[0015] Beneficial effects

[0016] The present invention provides an optimized control device for efficient and energy-saving power generation production in a thermal power plant. Compared with the prior art, it has the following beneficial effects:

[0017] 1. The optimized control device for power generation production in this highly efficient and energy-saving thermal power plant can make the two stirring rods connected to each ring rotate simultaneously through the use of motors. This can continuously change the positions of the stirring rods, prevent the stirring rods from always being in the flame, protect the stirring rods, reduce losses. When one stirring rod rotates, the moving rod moves along the groove, and its top is exposed on the support plate to stir the objects above, enabling the objects above to burn fully. When the other stirring rod rotates, it is in an inclined state, and under the action of gravity, it can automatically move downward, allowing the top of the other stirring rod to enter the inside of the ring. Since the two stirring rods at each ring are arranged in a staggered manner, different positions are stirred, enabling the objects inside to burn fully, saving energy. When the moving rod moves, the distance between the air inlet pipe and the cleaning block is reduced, cleaning the inner wall of the air inlet pipe, reducing the dust remaining in the air inlet pipe, preventing the combustion furnace from being easily filled with dust after long-term use, which may affect the ventilation effect inside the combustion furnace and thus the combustion of fuel, resulting in waste of fuel. Again, energy is saved, thus fully reducing energy waste, achieving high-efficiency energy conservation, and facilitating energy conservation.

[0018] 2. The optimized control device for power generation production in this highly efficient and energy-saving thermal power plant can be attached to the combustion furnace through the bladder. The airbag can sense the temperature inside the combustion furnace. If the temperature is too high, according to the principle of thermal expansion and contraction, the airbag can collide, causing the push plate to move. When the push plate moves, the inclined surface of the push plate gradually comes into contact with the top of the plug plate, causing the plug plate to move upward, increasing the distance between the bottom of the plug plate and the inner wall of the bottom of the pipe, allowing more gas to enter the inside of the pipe to blow the flame, making the flame larger. Thus, gas can be released according to the heat inside the combustion furnace, and it is preferably proportional to the flame situation, facilitating combustion inside.

[0019] 3. The optimized control device for power generation production in this highly efficient and energy-saving thermal power plant can make the toothed rail engage with the gear through the movement of the connecting rod, realizing the rotation of the gear. Since the gear is threadedly connected to the threaded rod, the threaded rod moves, pushing the moving rod to move, automatically moving the air inlet pipe at the top, enabling automated operation, reducing manual operation, and preventing burns.

[0030] Please refer to Figure 1 and 4, the connecting rod 23 is movably connected to the combustion furnace 1. A cross rod 24 is provided at the bottom of the connecting rod 23. A threaded rod 25 is provided on the outer side of one end of the cross rod 24. The threaded rod 25 is movably connected to the cross rod 24. A gear 26 is provided on the outer side of the threaded rod 25. The gear 26 is threadedly connected to the threaded rod 25. A toothed rail 27 is provided at the top of the gear 26. A movable rod 28 is provided at one end of the threaded rod 25. The threaded rod 25 is fixedly connected to the intake pipe 6 through the movable rod 28. A guiding rod 29 is provided at the bottom end of the intake pipe 6. A rectangular block 30 is provided on the outer side of one end of the guiding rod 29. The rectangular block 30 is movably connected to the guiding rod 29. The intake pipe 6 is in contact with the combustion furnace 1. A reinforcing rod 20 is provided on one side of the cleaning block 12. The cleaning block 12 is fixedly connected to the combustion furnace 1 through the reinforcing rod 20. The end of the stirring rod 9 is in an arc shape. A connecting spring is provided inside the groove 10.

[0031] During operation, when an object burns inside the combustion furnace 1, since the inner wall of the annular plate 3 is inclined, it can make the materials gather together as much as possible, facilitating the full combustion of the materials. First, the motor 5 is used. Since the end of the output shaft of the motor 5 is in transmission connection with the rotating rod 4, the rotation of the motor 5 drives the rotating rod 4 to rotate, and makes the ring 7 rotate, causing the stirring rod 9 to rotate. During the rotation of the stirring rod 9, the object on the support plate 2 can be stirred to allow the object above to burn fully. Moreover, through the rotation of the stirring rod 9, it can contact the fixed plate 8 and push the movement rod 11 to move, enabling the movement rod 11 to move along the groove 10 and stretch the connecting spring, causing the connecting spring to deform. Since the groove 10 is inclined, the rotation of one stirring rod 9 makes the movement rod 11 enter the inside of the groove 10 and separate from one stirring rod 9, making the bottom end of one stirring rod 9 contact the inclined surface of the fixed plate 8, causing one stirring rod 9 to move downward. Since the stirring rods 9 are all movably connected to the ring 7 and the rotating rod 4, it ensures the downward movement of the stirring rod 9, making the top end of the stirring rod 9 enter the inside of the ring 7, preventing the ring 7 from being unable to rotate due to the protrusion at the top end of the stirring rod 9. Through the rotation of the ring 7, the position of the stirring rod 9 can be continuously changed, preventing the stirring rod 9 from always being in the flame, protecting the stirring rod 9 and reducing wear. Moreover, when another stirring rod 9 rotates, it can make another stirring rod 9 in an inclined state. Under the action of gravity, another stirring rod 9 can automatically move downward, making the top end of another stirring rod 9 enter the inside of the ring 7 and contact the fixed plate 8, causing the top end of another stirring rod 9 to rotate onto the support plate 2. Through continuous rotation, it can contact the fixed plate 8, making another stirring rod 9 move upward and stirring the object above again. Moreover, the two stirring rods 9 at each ring 7 are arranged in a staggered manner to stir different positions and ensure the movement of the stirring rods 9. When the movement rod 11 moves, it drives the cross bar 21 fixedly connected to the movement rod 11 to move. When the cross bar 21 moves downward along with the movement rod 11, since one end of the cross bar 21 is movably connected to the sliding rod 22, the cross bar 21 can move downward. When the cross bar 21 moves towards the front, it can make the connecting rod 23 and the fixedly connected tooth rail 27 move simultaneously and engage with the gear 26, causing the gear 26 to rotate. Since the gear 26 is threadedly connected to the threaded rod 25, the threaded rod 25 moves along the cross bar 24, pushing the movable rod 28 to move. Moreover, the threaded rod 25 is fixedly connected to the air inlet pipe 6 through the movable rod 28, enabling the distance between the air inlet pipe 6 and the cleaning block 12 to be reduced, cleaning the inner wall of the air inlet pipe 6. Since the outer surface of the cleaning block 12 is horizontally collinear with the inner wall of the air inlet pipe 6, it reduces the dust remaining in the air inlet pipe 6, preventing the combustion furnace 1 from being easily filled with dust after long-term use, resulting in poor ventilation effect and affecting the combustion of fuel.This causes fuel waste and can automatically clean itself to prevent scalding. The reinforcing rod 20 moves together with the intake pipe 6 and moves along the guiding rod 29 to improve the stability of movement. During the long-term operation of the combustion furnace 1, since the airbag 17 is in contact with the combustion furnace 1, the temperature inside the combustion furnace 1 can be sensed through the airbag 17. If the temperature is too high, according to the principle of thermal expansion and contraction, the airbag 17 can collide, causing the push plate 16 to move. Since the push plate 16 is in contact with the exhaust fan 13, the exhaust fan 13 supports the push plate 16. When the push plate 16 moves, the inclined surface of the push plate 16 gradually comes into contact with the top end of the blocking plate 19, causing the blocking plate 19 to move upward. Since the blocking plate 19 is movably connected to the pipe 15, the distance between the bottom end of the blocking plate 19 and the inner wall of the bottom end of the pipe 15 is enlarged, allowing more gas to enter the interior of the pipe 15 and be released through the release pipe 14 to blow the flame, making the flame larger. Thus, gas can be released according to the heat inside the combustion furnace 1, which is approximately proportional to the flame situation, facilitating internal combustion.
