Abstract
Description
Technical Field
[0001] This invention relates to the technical field of boiler steam soot blowing optimization devices, specifically to a boiler steam soot blowing optimization device for thermal power plants. Background Technology
[0002] Soot blowers are generally installed on the furnace walls of boilers, including in the furnace, horizontal flue, and tail flue. They come in several types based on their structure, such as gun-type, rotary type, and telescopic type. Based on the medium used, they are classified into three categories: air soot blowers, steam soot blowers, and hydraulic soot blowers. Air soot blowers utilize the impact force of high-pressure compressed air to blow away ash accumulated on heated surfaces; they are commonly used in industrial boilers. Steam soot blowers utilize the impact force of a high-speed jet of superheated steam to remove ash from heated surfaces; they are mostly used in various power plant boilers. Hydraulic soot blowers, also known as "slag blowers," use high-pressure water as the medium, causing ash and slag adhering to heated surfaces to crack and be removed due to rapid cooling; they are only suitable for certain special applications. Ash accumulation on heated surfaces affects heat transfer, increases flue gas temperature, reduces boiler efficiency, and in severe cases, can cause superheater tube rupture accidents. Therefore, regularly using soot blowers to promptly remove ash from various heated surfaces plays a crucial role in ensuring the safe and economical operation of boilers.

[0005] 2. It cannot automatically adjust the depth of the soot blowing pipe into the area to be soot blown as needed;

If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
[0032] The present invention provides the following embodiments.
[0033] Example 1
[0034] This invention provides an optimized steam soot blowing device for thermal power plant boilers, such as... Figures 1-2As shown, the device includes a mounting plate 1, a support mechanism 2 fixedly connected to the top of the mounting plate 1, a moving mechanism 3 located at the bottom of the mounting plate 1, a soot blowing mechanism 4 fixedly connected to one side of the support mechanism 2, a support frame 5 fixedly connected to the top of the support mechanism 2, and an adjustment mechanism 6 located inside the support frame 5.
[0035] Preferably, the support mechanism 2 includes: a support column 7, the bottom of which is fixedly connected to the top of the mounting plate 1, and the top of the support column 7 is hinged to one side of the bottom of the support frame 5; the fixed end of the electric telescopic rod 8 is hinged to the side wall of the support column 7, and the telescopic end of the electric telescopic rod 8 is hinged to the bottom of the support frame 5.
[0036] Preferably, the moving mechanism 3 includes: a plurality of moving wheels 9, which are fixedly connected to the bottom periphery of the mounting plate 1 at intervals; and a driving device 10 is fixedly connected to one side of the top of the mounting plate 1, which is used to drive the moving mechanism 3.
[0037] Preferably, the adjustment mechanism 6 includes: a drive motor 11, which is embedded inside the support frame 5; a threaded rod 12 fixedly connected to the output shaft of the drive motor 11, with the right end of the threaded rod 12 rotatably connected to the inner wall of the support frame 5; two ends of a slide rod 13 fixedly connected to the inner wall of the support frame 5; the top of a slide 14 threadedly connected to the threaded rod 12, with the bottom of the slide 14 slidably connected to the slide rod 13; a cavity 141 and a cavity 142 are provided inside the slide 14; a drive motor 15 is embedded inside the slide 14; a drive shaft 16 is fixedly connected to the output shaft of the drive motor 15; and a gear 17 is fixedly connected to the drive shaft 16 inside the cavity 141.
[0038] The beneficial effects of the above technical solution are as follows:
[0039] When the aforementioned steam blowing optimization device for thermal power plant boilers performs soot blowing and cleaning on boilers of different specifications, several movable wheels 9 located at the bottom of the mounting plate 1 are driven by the drive device 10 to enable the steam blowing optimization device to move freely within the boiler at the soot blowing position. It can also cooperate with the soot blowing mechanism 4 to complete soot blowing at different locations. The support mechanism 2 located at the top of the mounting plate 1 controls the extension and retraction of the electric telescopic rod 8 when the angle of the support frame 5 needs adjustment. This causes the electric telescopic rod 8 to drive the support frame 5 to rotate up and down along the top of the support column 7, thereby enabling the soot blowing mechanism 4, which is mounted on the support frame 5, to blow... The adjustment of the ash angle; secondly, when the soot blowing mechanism 4 blows ash and cleans the inside of the boiler, the forward and reverse rotation of the drive motor 11 drives the threaded rod 12 to rotate in both directions, thereby realizing the left and right movement of the slide 14 threadedly connected to the threaded rod 12. At the same time, the drive motor 15 embedded in the slide 14 drives the drive shaft 16 to rotate, so that the gear 17 fixedly connected to the drive shaft 16 rotates in the cavity 141. The above-mentioned adjustment mechanism 6 can realize the left and right movement of the soot blowing mechanism 4 on the support frame 5 and the rotation of the soot blowing pipe 22, so as to complete the adjustment of the soot blowing and cleaning angle at different positions inside the boiler.
[0040] This invention, by setting up a moving mechanism 3 in conjunction with a supporting mechanism 2 and an adjusting mechanism 6, avoids the need for manual operation to adjust the soot blowing position of the steam soot blowing device, and automatically adjusts the soot blowing angle and insertion depth according to the type of boiler, which not only saves a lot of manpower, but also greatly reduces the labor intensity of manual labor.
[0041] This invention addresses the following problems encountered by existing steam soot blowing devices, such as the furnace steam soot blowing device described in CN103438468B, during the soot blowing process in boilers:
[0042] 1. The steam soot blowing device cannot adjust the soot blowing angle (such as the angle between the axial and horizontal directions of the soot blowing pipe) as needed;
[0043] 2. It cannot automatically adjust the depth of the soot blowing pipe into the area to be soot blown as needed;
[0044] Example 2
[0045] Based on Example 1, such as Figures 1-2As shown, the soot blowing mechanism 4 includes: a steam box 18, which is fixedly connected to the side wall of the support column 7 via a fixing plate 19; the air inlet of the conveying hose 20 is connected to the air outlet of the steam box 18; a solenoid valve 21 is connected to the conveying hose 20; a soot blowing pipe 22 passes through the middle of the slide 14 and the side wall of the support frame 5 from left to right; the soot blowing pipe 22 is rotatably connected to the slide 14; the soot blowing pipe 22 slides through the support frame 5; a number of air blowing ports 23 are provided at intervals on the side wall of the soot blowing pipe 22; and a nozzle 24 is connected to the right end of the soot blowing pipe 22; a telescopic conveying pipe 25 is connected to the air inlet of the conveying hose 20 and the soot blowing pipe 22; and a gear 26 is fixedly connected to the soot blowing pipe 22 in the cavity 141; and gear 17 meshes with gear 26.
[0046] Preferably, it also includes a dust collection mechanism, which is disposed in the cavity 2 142. The dust collection mechanism includes: a dust collection tank 27, which is fixedly connected to the bottom of the cavity 2 142; a dust collection pipe 28, which is embedded in the inside of the soot blowing pipe 22, and the side wall of the soot blowing pipe 22 is connected to the outer side wall of the soot blowing pipe 22 at intervals through several connecting pipes 29; the inlet of the conveying pipe 30 is rotatably connected to the dust collection pipe 28, and the outlet of the conveying pipe 30 is connected to the inlet of the dust collection tank 27; and a dust collection pump 31 is fixedly connected to the bottom of the cavity 2 142 and is connected to the conveying pipe 30.
[0047] Preferably, it also includes a dust removal mechanism 32, which is symmetrically arranged on the side wall of the soot blowing pipe 22. The upper dust removal mechanism 32 includes two fixed sleeves 33, which are fixedly connected to the side wall of the soot blowing pipe 22 at a distance from each other. The bottom of the fixed bracket 34 is slidably connected in the two fixed sleeves 33 respectively. The bottom of the fixed bracket 34 is connected to the bottom of the fixed sleeve 33 by a spring 35. The cleaning brush 36 is fixedly connected to the top of the fixed bracket 34.
[0048] The beneficial effects of the above technical solution are as follows:
[0049] The soot blowing mechanism 4, configured through the steam soot blowing optimization device, controls the closing of the solenoid valve 21 during soot blowing inside the boiler. This allows the steam in the steam box 18 to be pressurized by the booster pump and then transported through the solenoid valve 21 and the delivery hose 20 to the retractable delivery pipe 30. From there, the steam is transported through the retractable delivery pipe 25 to the soot blowing pipe 22. A portion of the steam entering the soot blowing pipe 22 is delivered to the boiler surface requiring soot blowing through several air outlets 23 on the wall of the soot blowing pipe 22. Another portion of the steam is transported along the soot blowing pipe 22 to a nozzle 24 fixedly connected to one end of the soot blowing pipe 22. The nozzle 24 then sprays high-pressure steam onto the area to be soot blown. In conjunction with the adjusting mechanism 6, the soot blowing pipe 22 is moved out of the support frame 5 and fixedly connected to the... Gear 26 on the soot blowing pipe 22 meshes with gear 17, driving the soot blowing pipe 22 to rotate on the slide 14. This allows steam to be output from several air outlets 23 and nozzles 24 to the soot blowing points at different positions and angles inside the boiler to complete soot blowing and cleaning. At the same time, while cleaning, the dust blown off by the soot blowing pipe 22 is carried by the dust pump 31 through the dust suction pipe 28 embedded in the soot blowing pipe 22. The dust blown off by the soot blowing pipe 22 enters the dust suction pipe 28 through several connecting pipes 29. The dust suction pipe 28 then transports the dust to the dust collection tank 27 through the conveying pipe 30. This completes the timely collection of the dust blown off by the soot blowing mechanism 4, preventing it from being dispersed in the air and spilled inside the boiler, which would reduce the soot blowing and cleaning efficiency of the steam soot blowing optimization device and make the cleaning effect worse.
[0050] Meanwhile, the cleaning mechanism 32, fixedly connected to the soot blowing pipe 22, works in conjunction with the soot blowing pipe 22. As the soot blowing pipe 22 rotates and moves left and right, the cleaning brush 36, fixedly connected to the top of the fixed bracket 34, cleans the dust. The spring 35 inside the fixed sleeve 33 provides cushioning for the fixed bracket 34 during cleaning, preventing the cleaning brush 36 from getting stuck during rotation and affecting the cleaning efficiency and effect of the cleaning mechanism 32. The invention, through the soot blowing mechanism 4, the dust suction mechanism, and the cleaning mechanism 32, enables accurate soot blowing and cleaning of different boiler internal structures during steam soot blowing and cleaning. It also allows for timely collection of fallen dust, effectively improving the soot blowing efficiency and cleaning effect of the steam soot blowing device, reducing worker workload, and demonstrating good performance.
[0051] This invention addresses the following problems encountered by existing steam soot blowing devices, such as the furnace steam soot blowing device described in CN103438468B, during the soot blowing process in boilers:
[0052] The lack of a dust collection mechanism makes it impossible to collect dust, thus affecting the soot blowing efficiency and cleaning effect of the steam soot blowing device.
[0053] Example 3
[0054] Based on Example 1 or 2, such as Figure 1 , Figures 3-5 As shown, it also includes an auxiliary cleaning mechanism 37, which is connected to the top of the support frame 5. The auxiliary cleaning mechanism 37 includes a rack 38, which is fixedly connected to the top of the support frame 5, and two fixed frames 39 are symmetrically connected to the side wall of the drive box 40.
[0055] A drive housing 40 has a rotating shaft 41 rotatably connected to the inner walls of both sides. A servo motor 42 is fixedly connected to the side wall of the drive housing 40, and the output shaft of the servo motor 42 is fixedly connected to the rotating shaft 41. A drive gear 43 is fixedly connected to the rotating shaft 41 and meshes with a rack 38. Two guide rods 44 are fixedly connected to the bottom of the drive housing 40 at a distance from each other, and a guide wheel 45 is rotatably connected to the bottom of the guide rods 44. The guide wheel 45 is in rolling connection with the side wall of the rack 38.
[0056] The top of the fixed rod 46 is fixedly connected to the bottom of the two fixed brackets 39, and the driven gear 47 is fixedly connected to the middle of the fixed rod 46. The driven gear 47 meshes with the rack 38, and the two sets of dust removal components 48 are respectively connected in the two fixed brackets 39.
[0057] Preferably, the dust removal assembly 48 includes: a cylinder 49 fixedly connected to the inner wall of the mounting bracket 39, and a mounting bracket 50 fixedly connected to the telescopic end of the cylinder 49; the bottom of the drive shaft 51 rotatably connected to the top of the mounting bracket 50; a worm gear 52 fixedly connected to the drive shaft 51; both ends of the worm 53 rotatably penetrating through the side wall of the mounting bracket 50; the worm gear meshing with the worm 53; and a sliding groove 54 embedded in the inner walls of both sides of the mounting bracket 39, with a sliding plate 55 slidably connected within the sliding groove 54. The two ends of the guide rod 56 are fixedly connected to the sliding plate 55. The two threaded rods 57 with opposite directions of rotation are fixedly connected to the two ends of the worm gear 53, and one end of the two threaded rods 57 is fixedly connected to the sliding plate 55. The two drive plates 58 are symmetrically threaded on the threaded rods 57, and the lower part of the drive plate 58 is slidably connected to the guide rod 56. The cleaning brush 59 is fixedly connected to the drive plate 58. The drive mechanism is set on the mounting bracket 50 and is used to drive the transmission shaft 51.
[0058] Preferably, the drive mechanism includes: a forward and reverse drive motor 60, which is fixedly connected to the rear side wall of the mounting bracket 50, and a first pulley 61 is fixedly connected to the output shaft of the forward and reverse drive motor 60, and a second pulley 62 is fixedly connected to the top of the transmission shaft 51, and the second pulley 62 and the first pulley 61 are driven by a belt 63.
[0059] The beneficial effects of the above technical solution are as follows:
[0060] By using the auxiliary cleaning mechanism 37 set on the top of the support frame 5, when it is necessary to perform all-round cleaning of different locations inside the boiler, it works together with the soot blowing mechanism 4. First, the servo motor 42 on the drive box 40 drives the rotating shaft 41 to rotate, so that the drive gear 43 fixedly connected to the rotating shaft 41 rotates synchronously. At the same time, the drive gear 43 meshes with the rack 38 fixedly connected to the top of the support frame 5, realizing the left and right movement of the drive box 40 along the rack 38. The guide rods 44, which are symmetrically distributed on both sides of the rack 38, are rotatably connected to the bottom of the drive box 40. The guide wheel 45 moves left and right with the drive box 40, making rolling contact with the side of the rack 38. This provides front and rear side correction for the movement of the drive box 40, preventing the fixed brackets 39, which are fixedly connected to both sides of the drive box 40, from derailing during left and right movement. At the same time, the driven gear 47, which is fixedly connected to the fixed rod 46 at the bottom of the fixed bracket 39, meshes with the rack 38 and rotates synchronously on the fixed rod 46. The rotation of the driven gear 47 on the fixed rod 46 also ensures the stable operation of the auxiliary cleaning mechanism 37 during operation, making the cleaning process more reliable. Meanwhile, the mechanism is also equipped with a fixed bracket... The dust removal assembly 48 within cylinder 39 operates smoothly. The extension and retraction of cylinder 49 allows the mounting bracket 50, fixedly connected to the extension end of cylinder 49, to move back and forth. During this movement, the worm gear 53 and threaded rod 57 drive the sliding plate 55 along the slide groove 54, ensuring smoother movement of the mounting bracket 50. Furthermore, the rotation of the forward and reverse drive motor 60 in the drive mechanism drives the pulley 61, fixedly connected to the output shaft of the forward and reverse drive motor 60, to rotate. The pulley 62, fixedly connected to the transmission shaft 51, meshes with pulley 61. The movement of the worm gear 52, fixedly connected to the transmission shaft 51, causes the worm gear 52 to rotate, meshing with the worm 53. This drives the two threaded rods 57, fixedly connected to both sides of the worm 53, to rotate synchronously. Simultaneously, two drive plates 58, threadedly connected to the threaded rods 57, move inward or outward along the guide rod 56. This causes the cleaning brushes 59, fixedly connected to the drive plates 58, to move left and right, cleaning the surfaces inside the boiler. Combined with the cleaning components 48 fixedly connected to both sides of the drive box 40, this completes comprehensive cleaning of different areas inside the boiler. This auxiliary cleaning mechanism 37 can perform comprehensive cleaning of the boiler interior while also cleaning the dust adhering to the inner and outer surfaces after steam soot blowing. It automatically adjusts the cleaning position according to the specific structure of the boiler, improving the overall cleaning effect of the steam soot blowing device, effectively extending the boiler's service life, ensuring the stability of the steam soot blowing optimization device's operation, and making it safer, more reliable, and effective.
[0061] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. 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.
