Description

Technical Field

[0001] The invention belongs to the technical field of generators, and in particular relates to a generator set based on a garbage incineration system. Background Art

[0002] The waste incineration power generation unit is a device that uses urban waste as fuel, generates heat energy through the incineration process, and converts the heat energy into electrical energy through a steam turbine. Its main purpose is to reduce the amount of waste, produce electricity, and realize the resource utilization of waste while processing urban waste. Waste incineration power generation not only solves the problem of waste disposal, but also uses the energy in the waste to produce electricity, reducing dependence on natural resources and reducing environmental pollution. It is an environmentally friendly and efficient way of modern urban waste disposal. Waste incineration can effectively eliminate harmful bacteria, parasites, mold, etc. in the waste, which helps to improve environmental sanitation. In addition, through a modern flue gas treatment system, toxic substances and waste gases can be prevented from being discharged into the atmosphere during the waste incineration process, thereby reducing air pollution.

[0003] However, since the contents of the garbage are not fixed and cannot burn stably like coal, the heat generated is also unstable, the combustion is not sufficient, and the amount of steam cannot be maintained stably. Since the alternating current generated by the generator is related to the speed of the steam turbine, the generator requires the steam turbine to provide a stable speed. Unstable steam cannot drive the steam turbine to rotate stably. Therefore, it is difficult for the garbage incineration power generation unit to control the speed of the steam turbine.

When the main shaft 10 rotates too fast, the rotation speed of the rotating shaft 73 increases. At this time, the counterweight ball 710 moves upward due to the lack of centripetal force, and the counterweight ball 710 drives the second connecting rod 78 to move through the third connecting rod 79.

[0049] The lower end of the rotating shaft 73 is fixedly connected to the second bevel gear 74, and the end of the main shaft 10 close to the outer shell 71 is fixedly connected to the first bevel gear 72.

The rotating sleeve 75 is rotatably connected to the outer side of the rotating ring 711. The end of the second connecting rod 78 away from the rotating sleeve 75 is rotatably connected to the third connecting rod 79. A spring 76 is provided between the rotating sleeve 75 and the top block 77.

[0050] A second gear 713 is rotatably connected in the outer shell 71, and a second rack 712 is fixedly connected to the rotating ring 711. The second rack 712 and the second gear 713 are meshed with each other. A fourth connecting rod 714 is fixedly connected to the second gear 713, and an end of the fourth connecting rod 714 away from the second gear 713 is fixedly connected to a ball sleeve 715, and a ball head 717 is movably connected in the ball sleeve 715. A fifth connecting rod 716 is rotatably connected in the outer shell 71, and one end of the fifth connecting rod 716 and the ball head 717 are slidably connected to each other.

[0051] A slide groove 719 is provided in the control valve 718, and a plurality of sliders 720 are slidably connected in the slide groove 719, and a moving block 721 is fixedly connected to each of the sliders 720, and a first cylinder 722 is fixedly connected to each of the moving blocks 721, and a rotating plate 723 is rotatably connected in the control valve 718, and a plurality of strip holes 724 are provided on the rotating plate 723, and the first cylinder 722 penetrates through the slidably connected strip hole 724, and a swing rod 725 is fixedly connected to one end of the rotating plate 723, and a second cylinder 726 is fixedly connected to the swing rod 725, and the second cylinder 726 penetrates through the slidably connected fifth connecting rod 716, and the fifth connecting rod The rod 716 drives the rocker arm 725 to rotate upward through the second cylinder 726, and the rocker arm 725 drives the rotating plate 723 to rotate.

Similarly, when the rotation speed of the medium and high pressure steam turbine 6 and the low pressure steam turbine 9 is reduced, the moving block 721 moves outward to increase the air intake of the steam pipe 5, thereby increasing the rotation speed of the main shaft 10 and maintaining the stability of power generation of the generator 11.

[0052] like Figure 10-Figure 17The reverse thrust furnace 3 is shown as follows. The reverse thrust furnace 3 is fixedly connected to the incinerator 1. The reverse thrust furnace 3 includes a fixed frame 315 slidably connected to the incinerator 1. A plurality of reverse thrust plates 39 are fixedly connected to the fixed frame 315. A flap 310 is rotatably connected to the reverse thrust plate 39. Both ends of the flap 310 are fixedly connected to a rotating shaft 311. A torsion spring 313 is sleeved on the rotating shaft 311. A first gear 314 is sleeved on the rotating shaft 311. One end of the torsion spring 313 is fixedly connected to the first gear 314. One end of the torsion spring 313 away from the first gear 314 is fixedly connected to the rotating shaft 311. The first gear 314 rotates under the drive of the first rack 318, driving the torsion spring 313 to tighten. At this time, the flap 310 is blocked by the fixed plate 32 and cannot bounce up. When the reverse thrust plate 39 moves upward for a distance, the flap 310 is separated from the blockage of the fixed plate 32 and bounces upward under the drive of the torsion spring 313, throwing the garbage into the air, so that the garbage is fully in contact with the air, thereby improving the combustion efficiency.

[0053] A drive box 31 is fixedly connected to one side of the incinerator 1, a plurality of fixed plates 32 are fixedly connected in the incinerator 1, and the reverse thrust plate 39 and the fixed plate 32 are arranged alternately. A first rack 318 is fixedly connected to both sides of the incinerator 1, and a plurality of guide rails 319 are fixedly connected to both sides of the incinerator 1. A plurality of rollers 317 are rotatably connected to both sides of the fixed frame 315, and the rollers 317 and the guide rails 319 are slidably connected. The first gear 314 and the first rack 318 are meshed with each other. A drive motor 33 is fixedly connected in the drive box 31, and a driving gear 34 is fixedly connected to the output end of the drive motor 33. A rotating rod 35 is rotatably connected in the drive box 31, and a driven gear 36 is fixedly connected to the rotating rod 35. The driving gear 34 and the driven gear 36 are meshed with each other. The ends are fixedly connected with a disc 37, and the disc 37 is rotatably connected with a first connecting rod 38. The end of the fixed frame 315 close to the driving box 31 is fixedly connected with a fixing rod 316, and the end of the disc 37 away from the disc 37 is rotatably connected with the fixing rod 316. The driving motor 33 drives the driving gear 34 to rotate, the driving gear 34 drives the driven gear 36 to rotate, the driven gear 36 drives the rotating rod 35 to rotate, the rotating rod 35 drives the disc 37 to rotate, the disc 37 drives the first connecting rod 38 to move, and the first connecting rod 38 drives the fixed frame 315 to move along the guide rail 319. The friction is reduced by using the roller 317. The fixed frame 315 drives the reverse thrust plate 39 to reciprocate, and the reverse thrust plate 39 cooperates with the fixed plate 32 to move the garbage toward the feed channel 15, thereby extending the incineration time of the garbage.

[0054] The limit block 321 is fixedly connected to the reverse thrust plate 39, and the flap 310 is fixedly connected with a baffle 320. The baffle 320 and the limit block 321 are mutually engaged and cooperated. A through hole 312 is opened on the rotating shaft 311, and the end of the through hole 312 away from the first gear 314 passes through the fixed connection through hole 312. When the reverse thrust plate 39 moves downward, the first gear 314 rotates in the opposite direction driven by the first rack 318, and the first gear 314 drives the rotating shaft 311 to rotate through the torsion spring 313, and the rotating shaft 311 drives the flap 310 to reset. In the process of the flap 310 being lifted upward, it is limited by the baffle 320 and the limit block 321, and at the same time, garbage is prevented from entering under the flap 310, and the flap 310 is lifted.

[0055] The working principle of this embodiment is as follows: garbage enters the reverse thrust furnace 3 in the incinerator 1 through the feed channel 15, air is supplied through the air inlet 2, and the ignition port 18 ignites to incinerate the garbage. During the incineration process, the driving motor 33 drives the active gear 34 to rotate, the active gear 34 drives the driven gear 36 to rotate, the driven gear 36 drives the rotating rod 35 to rotate, the rotating rod 35 drives the disc 37 to rotate, the disc 37 drives the first connecting rod 38 to move, and the first connecting rod 38 drives the fixed frame 315 to move along the guide rail 319. The friction is reduced by using the roller 317. The fixed frame 315 drives the reverse thrust plate 39 to reciprocate, and the reverse thrust plate 39 cooperates with the fixed plate 32 to move the garbage toward the feed channel 15, thereby extending the incineration time of the garbage and making the garbage burn more fully. The burned garbage is discharged through the slag discharge channel 16, and the smoke is discharged through the smoke exhaust channel 17.

[0056] During the movement of the reverse thrust plate 39, the first gear 314 rotates driven by the first rack 318, driving the torsion spring 313 to tighten. At this time, the flap 310 is blocked by the fixed plate 32 and cannot bounce up. After the reverse thrust plate 39 moves upward for a distance, the flap 310 breaks away from the obstruction of the fixed plate 32 and bounces upward driven by the torsion spring 313, throwing the garbage into the air, so that the garbage is fully in contact with the air, thereby improving the combustion efficiency. Then, when the reverse thrust plate 39 moves downward, the first gear 314 rotates in the opposite direction driven by the first rack 318, and the first gear 314 drives the rotating shaft 311 to rotate through the torsion spring 313, and the rotating shaft 311 drives the flap 310 to reset. In the process of the flap 310 being lifted upward, it is limited by the baffle bar 320 and the limit block 321.

[0057] The heat from the incineration of garbage is exchanged through the heat exchange tube 4, so that the water in the heat exchange tube 4 is converted into steam. The steam enters the medium and high pressure steam turbine 6 through the steam pipe 5, and the steam drives the medium and high pressure steam turbine 6 to rotate. Then the steam enters the low pressure steam turbine 9 through the connecting pipe 8 and drives the low pressure steam turbine 9 to rotate. The medium and high pressure steam turbine 6 and the low pressure steam turbine 9 drive the main shaft 10 to rotate, and the main shaft 10 drives the generator 11 to rotate to generate electricity. At the same time, the steam entering the low pressure steam turbine 9 is condensed into water through the condenser 12 below, and then the water is pumped back to the heat exchange tube 4 through the return pipe 14 by the water pump 13 to complete the cycle.

[0058] The main shaft 10 drives the first bevel gear 72 to rotate, the first bevel gear 72 drives the rotating shaft 73 to rotate through the second bevel gear 74, the rotating shaft 73 drives the third connecting rod 79 to rotate through the top block 77, and the third connecting rod 79 drives the counterweight ball 710 to rotate. When the main shaft 10 rotates too fast, the speed of the rotating shaft 73 increases. At this time, the counterweight ball 710 moves upward due to the lack of centripetal force, and the counterweight ball 710 drives the second connecting rod 78 to move through the third connecting rod 79. The second connecting rod 78 drives the rotating sleeve 75 to move upward to squeeze the spring 76. The rotating sleeve 75 drives the second rack 712 to move upward through the rotating ring 711. The second rack 712 drives the fourth connecting rod 714 to rotate upward through the second gear 713. The fourth connecting rod 714 is connected to the rotating ring 711. The ball sleeve 715 drives the ball head 717 to move, and the ball head 717 drives the fifth connecting rod 716 to rotate. The fifth connecting rod 716 drives the rocker arm 725 to rotate upward through the second cylinder 726. The rocker arm 725 drives the rotating plate 723 to rotate. The rotating plate 723 drives the moving block 721 to move inward through the cooperation of the strip hole 724 and the first cylinder 722, thereby reducing the gap of the control valve 718 and reducing the air intake of the steam pipe 5, thereby reducing the rotation speed of the medium and high pressure steam turbine 6 and the low pressure steam turbine 9. Similarly, when the rotation speed of the medium and high pressure steam turbine 6 and the low pressure steam turbine 9 is reduced, the moving block 721 moves outward to increase the air intake of the steam pipe 5, thereby increasing the rotation speed of the main shaft 10 and maintaining the stability of the power generation of the generator 11.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
