Description

Technical Field

[0001] This invention belongs to the field of power generation equipment technology, specifically a combustion aid device for the furnace of a thermal power unit. Background Technology

[0002] Energy demand is fundamental to modern society, with electricity playing a major role and demand increasing daily. However, the energy available for power generation is rapidly depleting. Simultaneously, pollution from the extraction and use of fossil fuels has significantly threatened human health and damaged the natural environment upon which we depend. To change this situation, we have been actively seeking clean alternative energy sources with abundant reserves. Currently, humanity has successfully developed various new clean energy sources, including nuclear power, hydropower, wind power, tidal power, and solar power. Except for nuclear power, most of these new clean energy sources share the common characteristics of low output and large fluctuations in energy output, causing some interference to the power grid. For these reasons, the proportion of new clean energy output in the power grid remains low, and the problem of wind and electricity curtailment is severe in some areas.

[0003] Currently, combustion-supporting devices are often used in reactors. Existing devices often use wind power to mix and blow pulverized coal into the reactor, where the coal is ignited and burned by a heater to achieve complete combustion. However, since the wind power blows the coal continuously, the coal blown into the reaction chamber may not burn completely, leading to coal waste. Therefore, a combustion-supporting device for the furnace of thermal power units is proposed to solve the problems mentioned in the background technology. Summary of the Invention

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] This invention utilizes the coordination between structures such as a mixing conveying pipe, a first gear, a fan-shaped opening, and a baffle plate to enable the device to control the coal powder as the amount conveyed by the airflow changes. By using a fan to deliver external airflow into the interior of the fixed block, the airflow causes the turbine fan to rotate, which in turn drives the second set of ring blocks and the second gear to rotate. This, in turn, causes the first gear to drive the first set of ring blocks and the baffle plate to rotate, resulting in the fan-shaped notch and the fan-shaped opening at the baffle plate intermittently coinciding. Simultaneously, the airflow from one end of the U-shaped pipe causes the coal powder inside the mixing conveying pipe away from the reactor body to be drawn out through the overlap of the fan-shaped notch and the fan-shaped opening at the baffle plate. The coal powder is then dispersed by the conical block and heated by the heating wire, igniting the coal powder.

[0020] This invention utilizes the cooperation between a fixed block, a funnel, a limiting rod, and a spring to prevent the accumulation of pulverized coal to be transported. The rotation of the first ring block drives the first actuating block to rotate. At this time, through the cooperation between the first and second actuating blocks, and the limiting action of the fixed block and the limiting rod on the middle of the funnel and the side near the reactor body respectively, the funnel will move back and forth, thereby shaking the pulverized coal accumulated inside the funnel, causing the pulverized coal to scatter and fall from the discharge port into the inner cavity of the mixing and conveying pipeline, which is beneficial to the subsequent transportation and combustion of pulverized coal.

[0021] This invention, through the cooperation of structures such as the telescopic lever, movable plate, secondary mixing conveying pipe, and connecting circular hole, enables the device to intermittently and twice separate and convey pulverized coal and air, thus promoting more complete combustion of the pulverized coal. When the funnel moves back and forth, it also drives the telescopic lever to move back and forth in the same direction. When the telescopic lever moves forward, the end of the lever near the movable plate will cause the movable plate to rotate, which in turn causes the toothed block to rotate. Simultaneously, when the telescopic lever moves in the opposite direction, the end of the lever near the movable plate will contact the outer surface of the movable plate and the toothed block, reducing the length of the telescopic lever. The telescopic lever will then move to the rear of the next movable plate, repeating the previous operation. This intermittently connects the secondary mixing conveying pipe to the mixing conveying pipe through the connecting circular hole, dispersing the pressure of the air and pulverized coal during continuous combustion in the mixing conveying pipe, thus promoting more complete combustion of the pulverized coal.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 9As shown, the present invention provides a furnace combustion aid device for a thermal power unit, comprising a mixing and conveying pipeline 1, a one-way valve 11, and a reactor body 5. A first set of ring blocks 2 is movably connected to the middle of the outer surface of the mixing and conveying pipeline 1. A first gear 3 is fixedly connected to the middle of the outer surface of the first set of ring blocks 2. A baffle plate 4 is fixedly connected to one side of the inner cavity of the first set of ring blocks 2. A support frame 15 is fixedly connected to one side of the reactor body 5. A U-shaped pipe 6 is fixedly connected to the inner cavity of the support frame 15. A second set of ring blocks 7 is movably connected to the middle of the upper outer surface of the U-shaped pipe 6. A second gear 8 is fixedly connected to the middle of the outer surface of the second set of ring blocks 7. A turbine fan 9 is fixedly connected to the inner cavity of the second set of ring blocks 7. A first connecting pipe 10 is fixedly connected to the inner cavity of the second set of ring blocks 7 on the side away from the reactor body 5. A fan-shaped opening 12 is provided on one side of the middle of the interior of the mixing and conveying pipeline 1. A conical block 13 is fixedly connected to the side of the cavity near the reactor body 5. A heating wire 14 is fixedly connected to the outer surface of the conical block 13 at equal angles. By using a fan to deliver external air to the interior of the fixed block 16, the turbine fan 9 will rotate due to the air force, thereby driving the second set of ring blocks 7 and the second gear 8 to rotate. This will cause the first gear 3 to drive the first set of ring blocks 2 and the baffle plate 4 to rotate, thereby causing the fan-shaped notch at the baffle plate 4 to intermittently overlap with the fan-shaped opening 12. At the same time, the air force blown from one end of the top of the U-shaped pipe 6 will drive the coal powder in the end of the mixing conveying pipe 1 away from the reactor body 5 to be sucked out through the overlap of the fan-shaped notch at the baffle plate 4 and the fan-shaped opening 12. Then it will be dispersed through the conical block 13, and then heated by the heating wire 14 to ignite the coal powder and deliver it into the inner cavity of the reactor body 5.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7As shown, a fixing block 16 is fixedly connected to the top of the mixing conveying pipe 1 on the side away from the reactor body 5. A funnel 18 is movably connected to the inner cavity of the fixing block 16. A discharge port 17 is opened at the top of the mixing conveying pipe 1 located directly below the fixing block 16. A limit rod 19 is fixedly connected to the bottom of the inner cavity of the mixing conveying pipe 1 on the side near the reactor body 5. A spring 20 is sleeved on the outer surface of the limit rod 19. A first actuating block 21 is fixedly connected to the outer surface of the first ring block 2 on the side away from the reactor body 5 at an equal angle. The bottom of the funnel 18 on the side near the spring 20 is fixedly connected to... A second actuating block 22 is connected; the rotation of the first ring block 2 drives the first actuating block 21 to rotate. At this time, through the cooperation between the first actuating block 21 and the second actuating block 22, and through the limiting action of the inside of the fixed block 16 and the limiting rod 19 on the middle part of the funnel 18 and the side near the reactor body 5 respectively, the funnel 18 will move back and forth in the front and back directions, thereby shaking the coal powder accumulated inside the funnel 18, causing the coal powder to scatter and fall from the discharge port 17 into the inner cavity of the mixing and conveying pipe 1, which is beneficial to the subsequent conveying and combustion of coal powder.

[0035] like Figure 1 , Figure 5 , Figure 8 , Figure 9 As shown, a limiting frame 23 is fixedly connected to the middle of one side of the reactor body 5. A telescopic lever 24 is movably connected to the outer surface of the limiting frame 23. A central rotating shaft 25 is fixedly connected to the top of the mixing conveying pipe 1 on the side away from the fixed block 16. A toothed block 26 is connected to the outer surface of the central rotating shaft 25 by a bearing. A connecting circular hole 30 is opened at equal angles in the annular shape inside the toothed block 26. A V-shaped spring plate 28 is fixedly connected at equal angles in the annular shape on the outer surface of the toothed block 26. A movable plate 27 is hinged at equal angles in the annular shape on the outer surface of the toothed block 26. A secondary mixing conveying pipe 29 is fixedly connected to the inner cavity of the top of the side of the mixing conveying pipe 1 away from the fixed block 16. A connecting stop bar 31 is fixedly connected to one side of the secondary mixing conveying pipe 29. When the funnel 18 moves in the back-and-forth direction, it will also drive the telescopic lever 24. When lever 24 moves forward and backward, and then moves towards the front, the end of lever 24 near the movable plate 27 will cause the movable plate 27 to rotate, which in turn will cause the toothed block 26 to rotate. At the same time, when lever 24 moves in the opposite direction, the end of lever 24 near the movable plate 27 will contact the outer surface of the movable plate 27 and the toothed block 26. At this time, the length of lever 24 will decrease, and lever 24 will move to the rear of the next movable plate 27, repeating the previous operation. This allows the connecting hole 30 to intermittently connect the auxiliary mixing conveying pipe 29 to the mixing conveying pipe 1, thereby dispersing the wind force and the pressure of continuous coal powder combustion at the mixing conveying pipe 1, making the coal powder burn more completely.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, the outer surface of the mixing conveying pipe 1 is fixedly connected to the inner cavity of the top of the support frame 15. The end of the mixing conveying pipe 1 near the reactor body 5 penetrates the side wall of the reactor body 5. The inner cavity of the middle part of the baffle plate 4 is movably connected to the middle part of the outer surface of the mixing conveying pipe 1. A fan-shaped notch is provided on one side of the bottom of the baffle plate 4, which cooperates with the fan-shaped opening 12. One end of the top of the one-way valve 11 is fixedly connected to the inner cavity of the bottom of the mixing conveying pipe 1 on the side away from the reactor body 5. The one-way valve 11 is located at the top of the first connecting pipe 10. The inner cavity of the middle part of the turbine fan 9 is movably connected to the middle part of the top outer surface of the U-shaped pipe 6. The first gear 3 and the second gear 8 mesh. The U-shaped pipe 6 is connected with the bottom of the mixing and conveying pipe 1 extending upwards at one end. With the U-shaped pipe 6 extending upwards through the bottom of the mixing and conveying pipe 1 and into the interior of the mixing and conveying pipe 1, when the wind blows into the interior of the mixing and conveying pipe 1 through the U-shaped pipe 6, the wind inside the mixing and conveying pipe 1 will tend to move towards the reactor body 5. At this time, the flow velocity is faster on the side closer to the reactor body 5, which causes the coal powder in the inner cavity of the mixing and conveying pipe 1 away from the reactor body 5 to be sucked out through the overlapping part of the fan-shaped notch and the fan-shaped opening 12 at the baffle plate 4.

[0037] It is worth noting that the design purpose of the first connecting pipe 10 is to ensure the balance of the internal air pressure when the coal powder in the inner cavity of the mixing conveying pipe 1 on the side away from the reactor body 5 is sucked out.

[0038] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, the discharge port 17 is located directly below the fixed block 16 and cooperates with the fixed block 16. The bottom of the funnel 18 is provided with a plate hole. The area of ​​the bottom of the funnel 18 is smaller than the area of ​​the bottom of the fixed block 16 and the discharge port 17. The first actuating block 21 and the second actuating block 22 are in contact and squeezed. The one-way valve 11 does not contact the U-shaped pipe 6. The front and rear ends of the elastic spring 20 are fixedly connected to the funnel 18 and the fixed block 16, respectively. The outer surface of the limiting rod 19 is movably sleeved with the inner cavity of the funnel 18. By designing that the bottom area of ​​the funnel 18 is smaller than the area of ​​the discharge port 17, the funnel 18 is given space to move back and forth inside the fixed block 16. At the same time, the function of the elastic spring 20 is to reset the funnel 18 after the first actuating block 21 and the second actuating block 22 come into contact.

[0039] like Figure 1 , Figure 5 , Figure 8 , Figure 9 As shown, the end of the limiting frame 23 away from the mixing conveying pipe 1 is fixedly connected to the bottom of the front and rear ends of the fixed block 16 near the reactor body 5. The telescopic lever 24 is fixedly connected to the side of the V-shaped spring plate 28 near the reactor body 5. The total number of movable plates 27 and V-shaped spring plates 28 is twice the total number of connecting holes 30. The side of the V-shaped spring plate 28 near the movable plate 27 is fixedly connected to the movable plate 27. The telescopic lever 24 cooperates with the movable plate 27. The connecting stop bar 31 cooperates with the movable plate 27 and engages with it. The connecting hole 30 is connected to the middle of the secondary mixing conveying pipe 29. The inner cavity is matched; through the proportional design of the connecting round hole 30 and the movable plate 27, the telescopic lever 24 is matched with the movable plate 27 in each cycle, so that the connecting round hole 30 is intermittently connected to the inner cavity of the middle part of the secondary mixing conveying pipe 29, thereby conveying the air blown out of the mixing conveying pipe 1 and the coal powder mixture for the second time. At this time, the air blown out of the mixing conveying pipe 1 will be blown out from one end of the mixing conveying pipe 1 located inside the reactor body 5. At this time, the coal powder from the secondary mixing conveying pipe 29 will be burned along with the coal powder blown out of the mixing conveying pipe 1.

[0040] Working principle and usage process of this invention:

[0041] First, a blower is used to deliver external airflow into the fixed block 16. At this time, due to the effect of the airflow, the turbofan 9 will rotate, thereby driving the second set of ring blocks 7 and the second gear 8 to rotate. This, in turn, causes the first gear 3 to drive the first set of ring blocks 2 and the baffle plate 4 to rotate. As a result, the fan-shaped notch at the baffle plate 4 intermittently overlaps with the fan-shaped opening 12. At the same time, the airflow from one end of the top of the U-shaped pipe 6 will drive the coal powder in the mixing conveying pipe 1 away from the reactor body 5 to be sucked out through the overlap of the fan-shaped notch at the baffle plate 4 and the fan-shaped opening 12. Then, it will be dispersed through the conical block 13 and then heated by the heating wire 14 to ignite the coal powder.

[0042] Simultaneously, the rotation of the first ring block 2 will also drive the first actuating block 21 to rotate. At this time, through the cooperation between the first actuating block 21 and the second actuating block 22, and through the limiting action of the inside of the fixed block 16 and the limiting rod 19 on the middle part of the funnel 18 and the side near the reactor body 5 respectively, the funnel 18 will move back and forth in the direction of reciprocating, thereby shaking the coal powder accumulated inside the funnel 18, causing the coal powder to fall and drop from the discharge port 17 into the inner cavity of the mixing and conveying pipe 1, which is beneficial to the subsequent conveying and combustion of coal powder.

[0043] Simultaneously, when the funnel 18 moves in the front-to-back direction, it also drives the telescopic lever 24 to move in the front-to-back direction. When the telescopic lever 24 moves towards the front, the end of the telescopic lever 24 near the movable plate 27 will drive the movable plate 27 to rotate, which in turn drives the toothed block 26 to rotate. At the same time, when the telescopic lever 24 moves in the reverse direction, the end of the telescopic lever 24 near the movable plate 27 will contact the outer surface of the movable plate 27 and the toothed block 26. At this time, the length of the telescopic lever 24 will decrease, and the telescopic lever 24 will move to the rear of the next movable plate 27, repeating the previous operation. This allows the connecting hole 30 to intermittently connect the auxiliary mixing conveying pipe 29 to the mixing conveying pipe 1, thereby dispersing the pressure of the wind and coal powder during continuous combustion at the mixing conveying pipe 1.
