Description

Technical Field

[0001] This utility model relates to the field of boiler cleaning technology, specifically to a shock wave soot blowing system for preventing blockage at the outlet and elbow of a fluidized bed boiler. Background Technology

[0002] For example, a shockwave soot blowing system for boilers, as disclosed in patent publication number CN209213887U, includes: an air pump, an air pressure reducing valve, a first flow meter, an air filter, a first solenoid valve, and a first check valve connected in sequence via pipes; a gas holder, a second check valve, a gas pressure reducing valve, a third check valve, a second flow meter, a second solenoid valve, and a fourth check valve connected in sequence via pipes; a backflushing mixing flame retardant, the inlet of which is connected to the outlet of the first check valve and the outlet of the fourth check valve respectively; the backflushing mixing flame retardant, an igniter, and at least two shockwave generators connected in sequence; a centrifugal fan connected to at least two output pipes via air supply pipes; and a control cabinet, the output of which is connected to the input of the first / second solenoid valves respectively, which can effectively prevent corrosion and blockage problems caused by flue gas backflow.

[0003] However, during the use of the above-mentioned equipment, due to the setting of its internal air pump, ash and slag are easily generated at the boiler outlet and elbow, which are difficult to clean and can lead to blockage, affecting the normal operation and thermal efficiency of the boiler. Therefore, we propose a more convenient and practical shock wave soot blowing system to meet the usage requirements. Utility Model Content

[0010] Furthermore, an air blowing pipe is fixedly connected to one end of the rotating tube, and a nozzle is installed at one end of the air blowing pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This shockwave soot blowing system, designed to prevent blockage at the boiler outlet and elbow of a fluidized bed boiler, utilizes an installation and rotation mechanism. During operation, the shockwave unit, support pipe, and outlet pipe are first connected. Then, the shockwave unit is activated, and gas flows through the support pipe, connecting pipe, fixed pipe, and rotating pipe into the blowing pipe and nozzle, blowing soot onto the boiler outlet and elbow. During soot blowing, a locking motor on the mounting plate drives a gear to rotate, which in turn rotates the gear ring and rotating pipe, adjusting the soot blowing angle of the blowing pipe and nozzle. This device allows for flexible adjustment of the soot blowing angle, effectively removing accumulated ash and slag at the boiler outlet and elbow, preventing blockage, ensuring normal boiler operation and thermal efficiency, and demonstrating strong practicality and suitability for widespread adoption.

[0013] Meanwhile, the installation mechanism ensures that the shock wave soot blowing system, after being installed near the fluidized bed furnace outlet and elbow, is not easily shaken or displaced by external vibrations or other factors, thus guaranteeing the normal operation of the system.

[0019] Soot blowing equipment is required during boiler operation. The soot blowing equipment provided by this utility model is specifically designed for soot blowing operations at the boiler outlet and elbow of the fluidized bed furnace during boiler operation. When using this equipment for soot blowing operations, it is necessary to ensure that all components are firmly connected and the 304 sealing gasket is intact to avoid air leakage. The soot blowing frequency should be reasonably arranged according to the boiler usage and the degree of ash accumulation. The soot blowing equipment should be maintained and serviced regularly, and the wear of each component should be checked. Damaged components should be replaced in a timely manner. At the same time, ash and debris should be cleaned to keep the equipment clean.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a shock wave soot blowing system for preventing blockage at the outlet and elbow of a fluidized bed furnace, including an outlet pipe 1. An installation mechanism 2 is provided on one side of the top of the outlet pipe 1 for installing equipment. A rotating mechanism 3 is provided on one side of the installation mechanism 2 for adjusting the soot blowing angle. The rotating mechanism 3 includes a shock wave generator body 301. A support pipe 302 is fixedly connected to the output end of the shock wave generator body 301. The support pipe 302 is connected to the outlet pipe 1. Through holes are opened on both sides of the support pipe 302. A connecting pipe 303 is fixedly connected in the through holes. A sealing gasket 304 is installed on one side of the connecting pipe 303. A rotating component is provided on one side of the sealing gasket 304.

[0021] like Figure 2As shown, the mounting mechanism 2 includes a base plate 201. First mounting blocks 202 are fixedly connected to both sides of the bottom of the base plate 201. The first mounting blocks 202 are connected to the shock generator body 301. Fixed frames 203 are fixedly connected to both sides of the top of the base plate 201. Sliding blocks 204 are slidably connected to the inner wall of the fixed frames 203. Multiple equidistant limiting holes 205 are opened on one side of the fixed frames 203. Limiting rods 206 are inserted into the limiting holes 205. The limiting rods 206 pass through the sliding blocks 204. Tightening rings 207 are threaded to both ends of the limiting rods 206. Second mounting blocks 208 are fixedly connected to both sides of the top of the sliding blocks 204.

[0022] It should be noted that during use, the base plate 201 and the shock generator body 301 are first connected by the first mounting block 202. Then, the sliding block 204 is moved to the designated position by the fixing frame 203, and the limiting rod 206 is inserted into the limiting hole 205 and the sliding block 204 to fix the position of the sliding block 204. The tightening ring 207 is then manually rotated to fix it. Finally, the equipment and pipeline support are connected by the second mounting block 208. The installation mechanism 2 can ensure that the shock wave soot blowing system is not easily shaken or displaced by external vibrations or other factors after installation near the fluidized bed furnace outlet and elbow, thus ensuring the normal operation of the system.

[0023] like Figure 3 As shown, a fixed tube 305 is fixedly connected to one side of the sealing gasket 304, and a rotating tube 306 is rotatably connected to the inner wall of one side of the fixed tube 305. The rotating assembly includes a gear ring 307, which is connected to the outer wall of the rotating tube 306.

[0024] It should be noted that during use, the shock generator body 301, support tube 302 and outlet pipe 1 are first connected. Then the shock generator body 301 is started. Gas enters the blowing pipe 311 and nozzle 312 through the support tube 302, connecting pipe 303, fixed pipe 305 and rotating pipe 306 and blows soot at the fluidized bed furnace outlet and elbow. During the blowing process, the locking motor 310 on the mounting plate 308 drives the gear 309 to rotate and drives the gear ring 307 and rotating pipe 306 to rotate, thereby adjusting the blowing angle of the blowing pipe 311 and nozzle 312. The rotating mechanism 3 can flexibly adjust the blowing angle, better adapt to different blowing needs and improve the blowing effect.

[0025] During use, the base plate 201 and the shocker body 301 are first connected via the first mounting block 202. Then, the sliding block 204 is moved to the designated position via the fixing frame 203, and the limiting rod 206 is inserted into the limiting hole 205 and the sliding block 204 to fix the position of the sliding block 204. The tightening ring 207 is then manually rotated to fix it. Finally, the equipment and pipeline support are connected via the second mounting block 208. Then, the shocker body 301 is started. During the soot blowing process, the locking motor 310 on the mounting plate 308 drives the gear 309 to rotate and drives the gear ring 307 and the rotating tube 306 to rotate, thereby adjusting the soot blowing angle of the blowing pipe 311 and the nozzle 312. This device can flexibly adjust the soot blowing angle, effectively remove the ash and slag accumulation at the outlet and bend of the fluidized bed boiler, prevent blockage, and ensure the normal operation and thermal efficiency of the boiler.
