Description

Technical Field

[0001] This invention relates to the field of thermal power generation technology, specifically to a dry slag removal system. Background Technology

[0002] Currently, most large and medium-sized thermal power plants use dry ash removal systems to treat the bottom ash generated by coal-fired boilers. Dry ash removal technology mainly utilizes specially designed steel belts to transport and cool hot ash. The transport process does not require water and there is no need to set up a ash water treatment system, which can reduce environmental pollution.

[0003] The dry ash removal system involves the continuous falling of bottom ash from a coal-fired boiler onto a conveyor belt. The high-temperature ash moves at low speed on the conveyor belt, and under negative pressure, a controlled small amount of ambient cold air enters the air-cooled dry ash removal machine in the opposite direction. This gradually cools the ash on the conveyor belt, allowing it to burn gradually. The cold air and the high-temperature ash undergo thorough heat exchange; the air absorbs the boiler's radiant heat and the sensible heat of the ash, cooling the ash to a medium-temperature ash of 100℃–200℃. Simultaneously, after heat exchange with the ash, the cold air's own temperature rises to 300℃–400℃ before it re-enters the coal-fired boiler.

[0004] The existing dry slag machine air inlet device has an adjustable air inlet on the outside of the dry slag machine casing, while the inside of the casing is open. After the cold air enters the casing, some of the cold air will directly enter the boiler furnace from the gap where the resistance is the least, thus bypassing the heat exchange of the dry slag machine conveyor belt, reducing the efficiency of cold slag, and also affecting the normal operation of the boiler.

When the cold air passes through the air guide plates, the air is guided towards the steel belt conveyor by the inclined end of the air guide plates. This increases the amount of cold air that exchanges heat with the hot slag on the steel belt conveyor, allowing for sufficient heat exchange between the cold air and the hot slag and improving the slag cooling efficiency.

[0026] The present invention provides the following embodiments.

[0027] Example 1

[0028] This invention provides a dry slag removal system, such as... Figure 1 As shown, the system includes a boiler 1, the outlet of which is connected to the feed inlet 2 of the slag removal shell 3. The slag removal shell 3 has a transmission chamber inside, which contains a transmission mechanism and several air guide plates 10. The discharge port 5 of the slag removal shell 3 is connected to the slag crushing mechanism, and the air inlet 9 of the slag removal shell 3 is connected to the air intake mechanism 8. The feed inlet 2, the discharge port 5, the air inlet and the air intake 9 are all connected to the transmission chamber.

[0029] The transmission chamber includes a horizontal transmission chamber 4 and a lifting transmission chamber 11. The upper end of the horizontal transmission chamber 4 is connected to the feed inlet 2, the upper end of the lifting transmission chamber 11 is connected to the air inlet 9, and the lower end of the lifting transmission chamber 11 is connected to the discharge outlet 5.

[0030] The transmission mechanism includes a steel belt conveyor 6 and a sweeper 7. The sweeper 7 is located below the steel belt conveyor 6, and the climbing angle of the sweeper 7 is smaller than the climbing angle of the steel belt conveyor 6.

[0031] The intake mechanism 8 is a rotary opening and closing mechanism;

[0032] The number of air guide plates 10 is two, and the two air guide plates 10 are respectively set in the horizontal transmission cavity 4 and the lifting transmission cavity 11. The air guide plate 10 is a U-shaped plate. The U-shaped hole of the air guide plate 10 is for the transmission mechanism to pass through. The opening of the U-shaped hole faces downward, and the upper end of the U-shaped hole is an inclined end, and the inclined direction is towards the top of the steel belt conveyor 6.

[0033] The beneficial effects of the above technical solution are as follows:

[0034] When the dry slag removal system is working, the hot slag in the furnace of boiler 1 is first discharged through the outlet onto the steel belt of the steel belt conveyor 6. The steel belt conveyor 6 drives the hot slag towards the discharge port 5. Utilizing the suction effect of the negative pressure generated by combustion in the furnace, cold air is drawn in through the air inlet 9 and the air intake. The rotating opening and closing mechanism (refer to CN202021969783 - Rotating opening and closing structure and exhaust fan outlet device) is used to regulate the amount of cold air drawn in. The cold air assists the unburned combustibles on the steel belt conveyor 6 to further burn and release heat. The cold air absorbs the high-temperature enthalpy in the slag, cooling the slag into medium-temperature ash. After heat exchange between the cold air and the slag, its own temperature rises to the target temperature, and then it enters boiler 1. The cleaner 7, composed of a chain and scrapers, transports the slag on the steel belt conveyor 6 or the fine ash spilled onto the cleaner 7 to the discharge port 5. In the transmission chamber, at the air inlet and air intake 9... An air guide plate is installed between the feed inlet 2 and the air inlet to prevent cold air from directly entering the furnace of the boiler 1 through the gap between the steel belt conveyor 6 and the transmission chamber. This ensures that the cold air entering the transmission chamber passes through the air guide plate 10 before entering the furnace of the boiler 1 through the feed inlet 2. When the cold air passes through the air guide plate 10, it is guided towards the steel belt conveyor 6 by the inclined end of the air guide plate 10. This increases the amount of cold air that exchanges heat with the hot slag on the steel belt conveyor 6, allowing for sufficient heat exchange between the cold air and the hot slag, thus improving the efficiency of cold slag cooling. This solves the technical problem of existing dry slag machine air inlets, which have adjustable air inlets on the outside of the dry slag machine casing while the inside of the casing is open. As a result, some of the cold air enters the boiler furnace directly from the gap with the least resistance after entering the casing, thus bypassing the heat exchange of the dry slag machine conveyor belt, reducing the efficiency of cold slag cooling, and affecting the normal operation of the boiler.

[0035] Example 2

[0036] Based on Example 1, such as Figure 2As shown, the slag crushing mechanism includes a slag crushing shell 14, which is fixedly connected to a slag removal shell 3. The slag crushing shell 14 has a slag crushing chamber 13 inside. Driving chambers 15 are symmetrically arranged on the left and right sides of the slag crushing chamber 13. A partition 16 is provided between the driving chambers 15 and the slag crushing chamber 13. A slag inlet 12 is provided at the upper end of the slag crushing chamber 13, which communicates with the transmission chamber. A slag outlet is provided at the lower end of the slag crushing chamber 13. The slag inlet 12, the slag crushing chamber 13, and the slag outlet are connected sequentially from top to bottom. The upper left and right ends of the slag crushing chamber 13 are respectively... A crushing block 20 is provided, and the crushing teeth on the crushing blocks 20 at both ends mesh with each other. The end of the crushing block 20 away from the crushing teeth is fixedly connected to the drive rod 29. The drive rod 29 passes through the partition 16 and is fixedly connected to the contact block 30 in the drive cavity 15. A spring is fixedly provided between the contact block 30 and the partition 16. The contact block 30 is slidably provided at the upper end of the drive cavity 15. The contact block 30 contacts the cam 33. The cam 33 is driven by the motor 21. A screening screen 17 is provided in the middle of the crushing cavity 13.

[0037] The motor 21 is fixedly installed on the side of the slag shell 14. The slag shell 14 has an opening for the cam 33 to pass through. The partition plate 16 has a groove 19 on the side near the slag inlet 12. The groove 19 cooperates with the crushed block 20.

[0038] The beneficial effects of the above technical solution are as follows:

[0039] Slag enters the crushing chamber 13 through the slag inlet 12. Slag smaller than the aperture of the screen 17 passes through the screen 17 and is discharged from the slag outlet. Slag larger than the aperture of the screen 17 is deposited on the screen 17. When the cam 33 rotates, the protruding end of the cam 33 contacts the contact block 30, pushing the contact block 30 towards the partition 16. The contact block 30 drives the drive rod 29 to move, and the drive rod 29 drives the crushing blocks 20 to move towards each other. The crushing blocks 20 drive the crushing teeth to move, and the crushing teeth on the left and right sides mesh with each other to crush the slag on the screen 17, so that the particle size of the slag on the screen 17 is smaller than the aperture of the screen 17, and can pass smoothly through the screen 17 and be discharged from the slag outlet, thus completing the purpose of crushing slag and crushing large pieces of slag to a volume that is easy to transport and use.

[0040] Example 3

[0041] Based on Example 2, such as Figure 2As shown, the slag shell 14 is provided with a drive screening mechanism, which includes a motor shaft 22. The motor shaft 22 is fixedly connected to the motor 21. The motor shaft 22 passes through the side end of the slag shell 14 and enters the drive cavity 15, and is fixedly connected to the bevel gear 23, the rotating cylinder 24 and the protrusion 28. The bevel gear 23 meshes with the bevel gear 31. The bevel gear 31 is fixedly connected to the cam 33 through the rotating shaft 32. The rotating shaft 32 is rotatably connected to the upper end of the drive cavity 15. The rotating cylinder 24 is provided with a spiral groove 25 on the outside. The spiral groove 25 is slidably connected to the guide ball 26. The guide ball 26 is rotatably connected to the vertical end of the L-shaped rod 27. The horizontal end of the L-shaped rod 27 is fixedly connected to the fixed block 36.

[0042] The protrusion 28 contacts the contact plate 34, the contact plate 34 is slidably connected to the sliding cavity 18, and the contact plate 34 passes through the sliding cavity 18 and is fixedly connected to the screening screen 17. The sliding cavity 18 is set through the left and right ends of the partition 16. The end of the contact plate 34 away from the protrusion 28 is slidably connected to the sliding rod 35. The sliding rod 35 is slidably connected to the fixed block 36. A second spring 37 is slidably provided between the fixed block 36 and the contact plate 34. The second spring 37 is sleeved on the sliding rod 35. The end of the sliding rod 35 away from the contact plate 34 contacts the connecting rod 38 in the drive cavity 15. A third spring 39 is fixedly provided between the connecting rod 38 and the lower end of the drive cavity 15. The middle part of the connecting rod 38 is rotatably connected to the partition 16 through the support shaft. The support shaft is fixedly set in the movable cavity. The movable cavity is set through the left and right ends of the partition 16, and the sliding cavity 18 and the movable cavity are distributed vertically. The connecting rod 38 in the slag cavity 13 is fixedly connected to the striking block 40. The striking block 40 is set on the lower side of the screening screen 17.

[0043] The beneficial effects of the above technical solution are as follows:

[0044] When the screening mechanism is in operation, the motor 21 is started, which drives the motor shaft 22 to rotate. The motor shaft 22 drives the bevel gear 23, the rotating cylinder 24, and the protrusion 28 to rotate. The bevel gear 23 drives the bevel gear 31 to rotate. The rotation of the bevel gear 31 drives the cam 33 to rotate. When the rotating cylinder 24 rotates, the spiral groove 25 engages with the guide ball 26, causing the guide ball 26 to reciprocate. The guide ball 26 drives the fixed block 36 to reciprocate. The fixed block 36 drives the sliding rod 35 to reciprocate along the contact plate 34. When the sliding rod 35 moves away from the partition plate 16, it pushes the connecting rod 38 to rotate. At this time, the spring 39 is compressed. At the same time, when the protrusion 28 rotates, the protruding end of the protrusion 28 contacts the contact plate 34, causing the contact plate 34 to slide downward along the sliding cavity 18. The contact plate 34 drives the sliding rod 35 to slide downward along the fixed block 34. 6. Moving downwards, the screening screen 17 moves downwards. The sliding rod 35 further drives the connecting rod 38 to rotate, and the second spring 37 is compressed. When the connecting rod 38 rotates, it drives the striking block 40 to rotate upwards, causing the striking block 40 to strike the screening screen 17, causing the slag on the screening screen 17 to vibrate and improving the screening effect of the screening screen 17. After the protruding end of the protrusion 28 disengages from the contact plate 34, the contact plate 34 moves upwards to return to its original position under the elastic action of the second spring 37. At the same time, the sliding rod 35 moves towards the partition plate 16. Under the elastic action of the third spring 39, the connecting rod 38 returns to its original position, causing the striking block 40 to return to its original position. During this process, the screening screen 17 moves up and down repeatedly, further improving the screening efficiency of the screening screen 17 and preventing slag from accumulating on the screening screen 17, which would affect the discharge of the crushing mechanism.

[0045] Example 4

[0046] Based on Example 1, such as Figure 3 As shown, an anti-deviation mechanism is provided between the driven transmission drum 41 and the steel belt 42 in the steel belt conveyor 6. The anti-deviation mechanism includes a mounting base 48, in which a sliding groove 44 is provided. Mounting blocks 43 are symmetrically arranged on the front and rear sides of the sliding groove 44. The mounting blocks 43 are symmetrically arranged on the front and rear sides of the driven transmission drum 41, and the mounting blocks 43 are rotatably connected to the drive shaft connected to the driven transmission drum 41. The front mounting block 43 is fixedly connected to the connecting rope 46. A guide wheel 45 is rotatably provided at the front end of the mounting base 48. The guide wheel 45 is connected to the connecting rope 46. 46 is fixedly connected to connecting block 1 47, connecting block 1 47 is slidably connected to the sliding port in connecting plate 58, connecting block 1 47 is fixedly connected to connecting block 3, a spring 5 is fixedly provided between connecting block 3 and connecting plate 58, connecting plate 58 is fixedly set in the middle of base 50, base 50 is fixedly set in the transmission cavity, the rear side of base 50 is rotatably connected to power shaft 51, power shaft 51 is fixedly connected to cam 2 52 and control motor, cam 2 52 contacts contact ball 1 49 and contact ball 2 53, contact ball 1 49 is rotatably connected to connecting block 1 47;

[0047] Contact ball 2 53 is rotatably connected to connecting block 2. Connecting block 2 is fixedly connected to sliding plate 54. Sliding plate 54 is slidably connected to connecting plate 58. Sliding plate 54 is fixedly connected to rack 55. Rack 55 passes through sliding hole 59 in fixed plate 56 and meshes with gear 60. Fixed plate 56 is fixedly connected to connecting plate 58. Spring 4 57 is fixedly provided between sliding plate 54 and fixed plate 56. Gear 60 is rotatably connected to fixed plate 56 through support rod. Gear 60 is eccentrically connected to rotating rod 61. Rotating rod 61 is rotatably connected to mounting block 43 on the rear side. Mounting plate is fixedly provided at the rear end of mounting base 48. Distance sensor 1 62 and distance sensor 2 63 are fixedly provided on mounting plate. Distance sensor 1 62 is correspondingly set to steel strip 42. Distance sensor 2 63 is correspondingly set to mounting block 43 on the rear side. Distance sensor 1 62 and distance sensor 2 63 are both connected to control motor through controller.

[0048] The beneficial effects of the above technical solution are as follows:

[0049] Distance sensor 62 is used to detect the distance between the mounting plate and the steel strip 42 in the front-to-back direction, and distance sensor 63 is used to detect the distance between the rear mounting block 43 and the mounting plate in the front-to-back direction. The controller controls the motor to work based on the detection values ​​of distance sensors 62 and 63. Initially, the difference between the detection values ​​of distance sensors 62 and 63 is a preset value. After the steel strip 42 shifts, the distance between the mounting plate and the steel strip 42 detected by distance sensor 62 in the front-to-back direction changes, causing the difference between the detection values ​​of distance sensors 62 and 63 to change. When a change occurs, the controller starts the control motor, which drives the cam 52 to rotate via the power shaft 51. As the cam 52 rotates, it pushes either contact ball 49 or contact ball 53 to move. Through the elastic action of springs 4 and 5, if contact ball 49 moves closer to the connecting plate 58, contact ball 53 moves away from the fixed plate 56; conversely, if contact ball 49 moves away from the connecting plate 58, contact ball 53 moves closer to the fixed plate 56. Contact ball 49 drives the connecting block 47 to move, and contact ball 53 drives the sliding plate 54 and rack 55 to move. The movement of rack 55 drives gear 6. Rotating gear 60 drives rotating rod 61 to rotate, which in turn causes mounting block 43 to slide along sliding groove 44. This causes a change in the distance between mounting block 43 and mounting plate detected by distance sensor 2 63 in the front-to-back direction. As mounting block 43 slides, it drives connecting rope 46 to move. Connecting rope 46 moves synchronously with connecting block 1 47. Under the combined action of connecting rope 46 and rotating rod 61, mounting block 43 slides stably along sliding groove 44. As mounting block 43 moves, it drives driven transmission cylinder 41 to move until the difference between the detection value of distance sensor 1 62 and the detection value of distance sensor 2 63 returns to the preset value. The controller stops controlling the motor. By setting an anti-deviation mechanism, the driven transmission drum 41 automatically matches the deviation direction of the steel belt 42, ensuring the stability of the steel belt conveyor 6 during the conveying process and improving the service life of the steel belt 42. The above-mentioned anti-deviation mechanism can also be used in the sweeper 7. An alarm can be added to the anti-deviation mechanism and connected to the controller. If the distance between the mounting plate and the steel belt 42 detected by the distance sensor 62 in the front-to-back direction is too large, it indicates that the deviation distance of the steel belt 42 is large enough and has exceeded the adjustment distance of the driven transmission drum 41. At this time, the controller controls the alarm to sound, reminding the staff to maintain the steel belt 42 in time.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
