Description

Technical Field

[0001] The present application relates to the technical field of coal-fired boilers, and in particular to a combustion-side coupled coal-fired boiler. Background Art

[0002] The combustion side coupled coal-fired boiler is a power generation method that combines biomass gasification technology with coal-fired boilers. This technology introduces the fuel gas produced by biomass gasification on the combustion side and mixes it with the pulverized coal in the coal-fired boiler to improve power generation efficiency and reduce environmental pollution. The fuel gas produced by biomass gasification is rich in volatile matter, which can promote the ignition and combustion of pulverized coal, while reducing CO2 and NOx emissions.

[0003] The combustion efficiency of existing coal-fired boilers is closely related to the size of the coal. When the coal is too large, the residence time of the coal particles in the boiler is too short, resulting in incomplete combustion of the coke, increasing the carbon content in the slag, and thus increasing physical heat loss.

[0004] In the operation of existing coal-fired boilers, the uneven size of the coal fed is a common problem. This inconsistency causes uneven combustion of the coal in the furnace, which in turn affects the combustion efficiency and the effective conversion of heat energy. At the same time, after entering the boiler, the larger coal cannot be quickly and effectively mixed with the gas generated by biomass gasification for combustion, which not only leads to incomplete combustion, increases the emission of unburned carbon, reduces boiler efficiency, but also reduces power generation efficiency. For this reason, the present application provides a combustion-side coupled coal-fired boiler. Summary of the invention

[0035] When in use, first pour the coal to be burned from the top of the loading box 2, and then the coal will fall on the crushing component according to the influence of gravity. At this time, the crushing component can be started to operate to simply crush the coal. While the crushing component is operating, it will also drive the auxiliary component to operate together. The operation of the auxiliary component can not only assist in crushing the coal accumulated above the crushing component, but also dredge the top of the crushing component to reduce the occurrence of coal blockage. In this way, through the cooperation of the crushing component and the auxiliary component, larger coal can be broken into small pieces, effectively avoiding uneven combustion in the furnace after the larger coal enters the boiler tower 1, greatly improving the efficiency of the coal crushing process. The combustion efficiency and the effective conversion of heat energy are improved. At the same time, after the coal is crushed, it can enter the boiler in a smaller form, so that it can be quickly and effectively mixed with the gas generated by biomass gasification for combustion, making the combustion more complete, reducing the emission of unburned carbon, and improving the boiler efficiency and power generation efficiency. After the crushing component and the auxiliary component initially crush the coal, it will fall on the filter plate 17 according to the influence of gravity, and then the fine coal will fall into the coal delivery pipe 3 through the multiple filter holes set on the filter plate 17. At this time, the auger inside the coal delivery pipe 3 can push the coal into the boiler tower 1 to be burned and mixed with the gas generated by biomass gasification: In addition, while the crushing component is running, the internal shaking component will also be started. At this time, the filter plate 17 can be intermittently hit by the shaking component, so that the filter plate 17 vibrates intermittently up and down inside the feeding box 2, so that the fine coal falling on the filter plate 17 can pass through the filter plate 17 more quickly, reducing the blockage of the filter plate 17. In the process of crushing the coal, a small amount of coal will fall directly on the filter plate 17 without being crushed, so that the uncrushed and larger coal cannot fall from the filter hole. At this time, the extrusion component can be started at the same time, so that the filter plate 17 can collide with the extrusion component when shaking. At this time, the coal can be squeezed and crushed again by the extrusion component, thereby greatly improving the practicality of the device and better burning.

[0037] When in use, first start the motor 7 to drive the rotating shaft 4 to rotate. At this time, one of the gears 8 will be driven to rotate through the guidance of the rotating shaft 4, and because the two gears 8 are meshed with each other, the other gear 8 will also rotate. At this time, through the mutual cooperation of the two gears 8, the two squeezing rollers 6 can be rotated in relative directions. At this time, when the coal falls on the two squeezing rollers 6, the two squeezing rollers 6 will squeeze the coal together to crush it, so that the larger coal is broken into small pieces, effectively avoiding uneven combustion in the furnace due to the larger coal entering the boiler tower 1, and greatly improving the combustion efficiency and the effective conversion of heat energy.

Driving members are arranged at both ends of the two moving blocks 9. The side of the two moving blocks 9 away from the crushing cone 10 is evenly and fixedly connected with multiple springs 16, and one end of the multiple springs 16 away from the moving block 9 is fixedly connected to the inner wall of the loading box 2. The driving member includes two sliding plates 11 symmetrically and slidably connected to the two sides of the loading box 2, and the middle sections of the opposite surfaces of the two sliding plates 11 are fixedly connected with a protrusion 12. Both ends of the rotating shaft 14 and the rotating shaft 2 5 are fixedly connected with a cam 13, and the protruding end of the cam 13 can contact the protruding end of the protrusion 12. Two sliding grooves 14 are evenly and symmetrically opened on both sides of the loading box 2, and one side of the two sliding plates 11 is symmetrically and fixedly connected with a connecting plate 15, which is slidably connected in the sliding groove 14, and one end of one connecting plate 15 is fixedly connected to one end of the moving block 9.

[0039] When in use, as the rotating shaft 14 and the rotating shaft 2 5 gradually rotate, the cams 13 at both ends will be driven to rotate cyclically together, so that the protruding ends of the two cams 13 will intermittently hit the protrusions 12, and when the protrusions 12 are hit, the sliding plate 11 will drive the two connecting plates 15 to slide inside the slide groove 14, so that the two moving blocks 9 will be driven to slide back and forth inside the loading box 2 through the guidance of the connecting plates 15, and when the protruding ends of the cams 13 are separated from the protrusions 12, at this time, according to the rebound of the springs 16, the two moving blocks 9 will be driven to approach each other, so that by continuously hitting the protrusions 12, the two moving blocks 9 can drive multiple crushing cones 10 to cyclically squeeze and collide above the squeezing roller 6, which can not only assist in crushing the coal accumulated above the squeezing roller 6, but also dredge the area above the squeezing roller 6 to reduce the occurrence of coal blockage.

[0040] Reference Figure 4 , Figure 5 and Figure 6The shaking assembly includes a rotating rod 19 that penetrates and rotates inside the feeding box 2, one end of the rotating shaft 5 is fixedly connected to a pulley 20, one end of the rotating rod 19 is fixedly connected to a pulley 21, a connecting belt 22 is sleeved on the pulley 20 and the pulley 21, and two cams 23 are symmetrically fixedly connected to the rotating rod 19, and the two cams 23 are located at the bottom of the filter plate 17; Secondly, both ends of the filter plate 17 are fixedly connected with a movable groove 30, and fixed plates 31 are opened on both sides of the interior of the loading box 2. The movable groove 30 is slidably connected in the fixed plate 31, and the upper and lower ends of the movable groove 30 are fixedly connected with a spring three 32, and the end of the spring three 32 away from the movable groove 30 is fixedly connected to the inner wall of the fixed plate 31.

[0041] During use, as the motor 17 drives the rotating shaft 25 to rotate continuously, it will also drive the pulley 1 20 to rotate. At this time, through the guidance of the connecting belt 22, the pulley 21 and the rotating rod 19 will be driven to rotate continuously, and through the rotation of the rotating rod 19, the two cams 23 will also be driven to rotate together. At this time, as the cam 23 continues to rotate, it will intermittently hit the bottom of the filter plate 17. When the filter plate 17 is impacted, it will drive the movable grooves 30 at both ends to slide in the fixed plate 31 and squeeze the spring 32. When the protruding end of the cam 23 separates from the bottom of the filter plate 17, the rebound of the spring 32 will drive the filter plate 17 to shake inside the feeding box 2, so that the fine coal falling on the filter plate 17 can pass through the filter plate 17 more quickly, reducing the blockage of the filter plate 17.

[0042] Reference Figure 4 and Figure 5 The extrusion assembly includes a screw rod 24 rotatably connected to the inside of the feeding box 2, a motor 25 is fixedly connected to one side of the inside of the feeding box 2, the output end of the motor 25 is fixedly connected to one end of the screw rod 24, a threaded sleeve 26 is threadedly connected to the screw rod 24, one end of the threaded sleeve 26 is fixedly connected to a connecting rod 27, a plurality of crushing hammers 28 are evenly fixedly connected to the bottom of the connecting rod 27, and the plurality of crushing hammers 28 are located above the filter plate 17, a guide groove 29 is penetrated through one side of the baffle 18, and the threaded sleeve 26 is slidably connected to the inside of the guide groove 29.

[0043] During use, during the process of crushing the coal, a small amount of coal will fall directly onto the filter plate 17 without being crushed, so that the uncrushed and larger coal cannot fall from the filter hole. At this time, the motor 25 can be started to drive the screw rod 24 to rotate. Then, through the rotation of the screw rod 24, the threaded sleeve 26 will slide back and forth on the screw rod 24 according to the guidance of the guide groove 29. At this time, the connecting rod 27 and the multiple crushing hammers 28 at the bottom will be driven by the threaded sleeve 26 to move back and forth above the filter plate 17. Therefore, when the filter plate 17 shakes, the top of the filter plate 17 will collide with the multiple crushing hammers 28. At this time, the coal can be squeezed and crushed again by the multiple crushing hammers 28, thereby greatly improving the practicability of the device and better burning.

[0044] The implementation principle of a combustion-side coupled coal-fired boiler in this embodiment is as follows: when in use, first pour the coal to be burned from the top of the loading box 2, and then the coal will fall on the squeezing roller 6 according to the influence of gravity. At this time, the motor 7 can be started to drive the rotating shaft 4 to rotate. At this time, one of the gears 8 will be driven to rotate through the guidance of the rotating shaft 4, and because the two gears 8 are meshed with each other, the other gear 8 will also rotate together. At this time, through the mutual cooperation of the two gears 8, the two squeezing rollers 6 can be rotated in opposite directions. At this time, when the coal falls on the two squeezing rollers 6, the two squeezing rollers 6 will squeeze the coal together. The larger coal is broken into small pieces, which effectively avoids the uneven combustion in the furnace due to the larger coal entering the boiler tower 1, greatly improving the combustion efficiency and the effective conversion of heat energy. As the rotating shaft 1 4 and the rotating shaft 2 5 gradually rotate, the cams 13 at both ends are driven to rotate together in a cycle, so that the protruding ends of the two cams 13 intermittently hit the protrusions 12. When the protrusions 12 are hit, the sliding plate 11 drives the two connecting plates 15 to slide inside the slide groove 14, so that the two moving blocks 9 are driven to slide back and forth inside the charging box 2 through the guidance of the connecting plate 15. When the cam 13 When the protruding end is separated from the protruding block 12, the rebound of the spring 16 will drive the two moving blocks 9 to approach each other, so that by continuously impacting the protruding block 12, the two moving blocks 9 can drive multiple crushing cones 10 to cyclically squeeze and collide above the squeezing roller 6, which can not only assist in crushing the coal accumulated above the squeezing roller 6, but also dredge the area above the squeezing roller 6 to reduce the occurrence of coal blockage. In this way, through the cooperation of the squeezing roller 6 and the crushing cone 10, larger coal can be broken into small pieces, effectively avoiding uneven combustion in the furnace after the larger coal enters the boiler tower 1, and greatly improving the combustion efficiency. The coal can be crushed into smaller pieces and then mixed with the gas generated by biomass gasification to achieve more complete combustion, reduce the emission of unburned carbon, and improve the efficiency of boiler and power generation. After the coal is initially crushed by the squeezing roller 6 and the crushing cone 10, it will fall on the filter plate 17 under the influence of gravity, and then the fine coal will fall into the coal delivery pipe 3 through the multiple filter holes provided on the filter plate 17. At this time, the auger inside the coal delivery pipe 3 can push the coal into the boiler tower 1 for combustion and mixing with the gas generated by biomass gasification. In addition, as the motor 17 drives the rotating shaft 25 to rotate continuously, the pulley 1 20 will also be driven to rotate. At this time, the pulley 21 and the rotating rod 19 will be driven to rotate continuously through the guidance of the connecting belt 22, and the rotation of the rotating rod 19 will drive the two cams 23 to rotate together. At this time, as the cam 23 continues to rotate, it will intermittently hit the bottom of the filter plate 17. When the filter plate 17 is impacted, the moving grooves 30 at both ends will be driven to slide in the fixed plate 31 and squeeze the spring 32. When the protruding end of the cam 23 separates from the bottom of the filter plate 17, the filter plate 17 will be driven to shake inside the feeding box 2 according to the rebound of the spring 32, so that the fine coal falling on the filter plate 17 can pass through the filter plate 17 more quickly, reducing the filter plate 17. 17 is blocked, and in the process of crushing the coal, a small amount of coal will fall directly on the filter plate 17 without being crushed, so that the uncrushed and larger coal cannot fall from the filter hole. At this time, the motor 25 can be started to drive the screw rod 24 to rotate, and then the threaded sleeve 26 will slide back and forth on the screw rod 24 according to the guidance of the guide groove 29 through the rotation of the screw rod 24. At this time, the connecting rod 27 and the multiple crushing hammers 28 at the bottom will be driven by the threaded sleeve 26 to move back and forth above the filter plate 17. Therefore, when the filter plate 17 shakes, the top of the filter plate 17 will collide with the multiple crushing hammers 28. At this time, the coal can be squeezed and crushed again by the multiple crushing hammers 28, thereby greatly improving the practicability of the device and better burning.
