Description

Technical Field

[0001] This invention relates to the field of flue gas ash removal technology, specifically a pulse purging system for dust removal pipelines. Background Technology

[0002] In the operation of coal-fired and oil-fired boilers, ash generally accumulates on the tail heating surface, which increases flue gas resistance and raises exhaust temperature, seriously affecting the normal operation of the boiler. Therefore, it is necessary to remove ash from the ash-accumulated areas. Currently, ash removal using pulse soot blowers is a new generation of ash removal technology. It utilizes acetylene combustion in a specially designed combustion chamber and emits shock waves from the nozzles on the output pipe. The shock waves cause the ash on the heating surface to fall off.

[0003] A search revealed an energy-saving pulse sootblower structure (publication number CN 219775775 U). One end of the air outlet pipe is fixed to a connecting pipe, and a nozzle is installed outside the connecting pipe. Symmetrically arranged connecting sleeves are positioned outside the air outlet pipe. A limiting rod is provided on the inner side of the connecting sleeve outside the nozzle, and a limiting hole adapted to the limiting rod is opened on the outer side of the nozzle. An air inlet pipe is connected to the air inlet end of the pulse canister body, and a filter cylinder is threaded onto the outer side of the air inlet pipe. The filter cylinder contains a filter screen and a dehumidifying screen arranged from top to bottom. This invention utilizes the connecting sleeves to cause the spring to deform under tension, increasing the distance between the two connecting sleeves. At this time, the nozzle can be installed outside the connecting pipe, and the limiting rod is simultaneously embedded into the limiting hole, allowing for quick nozzle installation. This design is convenient and allows for rapid nozzle replacement.

[0004] However, the above-mentioned pulse soot blowers still have some shortcomings in use. They are troublesome to install and disassemble with the pipeline, making disassembly and maintenance inconvenient. The soot blowing range is limited. Soot blowing is relatively clean near the nozzle, but the area far from the nozzle cannot be effectively cleaned, making it inconvenient to use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dust removal pipeline pulse purging system, which solves the problems of cumbersome installation and disassembly of pipelines, inconvenience in disassembly and maintenance, limited ash blowing range, relatively clean ash blowing near the nozzles, but ineffective ash removal and cleaning in areas far from the nozzles, and inconvenience in use.

[0006] This invention provides the following technical solution: a dust removal pipeline pulse purging and ash removal system, comprising a mounting plate, a threaded rod rotatably connected to one side of the mounting plate, a threaded sleeve threaded onto the surface of the threaded rod, a sliding rod fixedly connected to one side of the mounting plate, a sliding sleeve slidably fitted onto the surface of the sliding rod, an air outlet ring pipe fixedly fitted onto the outer surfaces of the sliding sleeve and the threaded sleeve, an air outlet nozzle being provided on the air outlet ring pipe, two storage cylinders fixedly connected to one side of the mounting plate, one end of each of the two storage cylinders extending to the other side of the mounting plate and having an opening, a pulse tank fixedly connected to the side of each of the two storage cylinders, an air outlet pipe connected to the air outlet end of each of the two pulse tanks, one end of each of the two air outlet pipes extending into the interior of the two storage cylinders respectively, two connecting pipes connected to the surface of the air outlet ring pipe, one end of each of the two connecting pipes being connected to the two air outlet pipes respectively, multiple fixing components being provided on the mounting plate, and electromagnetic valves being provided on each of the two air outlet pipes.

A limit hole is formed on the short plate, and a limit rod is slidably fitted into the inside of the limit hole. The limit rod is fixedly connected to the fixing plate.

[0009] Preferred technical solution 3: A mounting groove is provided on one side of the mounting plate, and a sealing gasket is provided between the inner walls of the mounting groove.

[0010] Preferred technical solution four: Each air outlet nozzle has a short pipe connected to its air inlet end, and each short pipe has an external thread on its surface.

[0014] Compared with existing technologies, this invention provides a pulse purging dust removal system for dust collection pipelines, which has the following advantages: In use, the cleaning ring, threaded rod, and exhaust ring pipe are inserted into the pipeline, with one end of the pipeline inserted into the mounting groove. Then, by rotating the screw on the fixing assembly, the fixing plate is pressed and fixed onto the pipeline, thus securing the device to the pipeline quickly and easily. Next, by controlling the solenoid valve, the pulse gas from the canister is sprayed through the connecting pipe and exhaust nozzle to clean the inner wall of the pipeline. Simultaneously, the rotation of the drive motor drives the threaded rod to rotate, thereby moving the threaded sleeve, sliding sleeve, and exhaust ring pipe, facilitating dust removal and cleaning of different locations inside the pipeline. After cleaning, the device is removed from the pipeline by reversing the screw. The cleaning ring and brush further clean the inner wall of the pipeline. This pulse purging dust removal system allows for quick installation and disassembly of the pipeline, and can thoroughly clean and blow dust from different locations within the pipeline, resulting in a cleaner and more convenient cleaning process.

[0022] Please see Figure 1-6 ,

[0023] Example 1: A dust removal pipeline pulse purging system includes a mounting plate 1. A threaded rod 2 is rotatably connected to one side of the mounting plate 1. A threaded sleeve 3 is threadedly fitted onto the surface of the threaded rod 2. A sliding rod 4 is fixedly connected to one side of the mounting plate 1. A sliding sleeve 5 is slidably fitted onto the surface of the sliding sleeve 4. An air outlet ring pipe 6 is fixedly fitted onto the outer surfaces of the sliding sleeve 5 and the threaded sleeve 3. An air outlet nozzle 7 is provided on the air outlet ring pipe 6. Two storage cylinders 8 are fixedly connected to one side of the mounting plate 1. One end of each storage cylinder 8 extends to the other side of the mounting plate 1 and has an opening. A pulse tank 9 is fixedly connected to the side of each storage cylinder 8. An air outlet pipe 10 is connected to the air outlet end of each pulse tank 9. One end of each air outlet pipe 10 extends into the interior of each storage cylinder 8. Two connecting pipes 11 are connected to the surface of the air outlet ring pipe 6. One end of each connecting pipe 11 is connected to the two air outlet pipes 10. Multiple fixing components 12 are provided on the mounting plate 1. Solenoid valves are provided on each of the two air outlet pipes 10.

[0024] Example 2: The difference between this example and Example 1 is that a drive motor 13 is fixedly connected to the side of the mounting plate 1. The output end of the drive motor 13 passes through the connected mounting plate 1 and is fixedly connected to one end of the threaded rod 2. The rotation of the drive motor 13 automatically drives the air outlet ring pipe 6 to move and clean different positions on the inner wall of the pipe.

[0025] Example 3: The difference between this example and Example 1 is that the fixing component 12 includes a short plate 14 fixedly connected to the mounting plate 1. The surface of the short plate 14 has a threaded hole 15. A lead screw 16 is threaded into the inside of the threaded hole 15. The bottom end of the lead screw 16 is rotatably connected to a fixing plate 17. A limit hole 18 is opened on the short plate 14. A limit rod 19 is slidably connected inside the limit hole 18. The limit rod 19 is fixedly connected to the fixing plate 17, which facilitates the installation of the pulse purging ash removal system on the pipeline and allows for quick installation and disassembly.

[0026] Example 4: The difference between this example and Example 1 is that an installation groove 20 is provided on one side of the mounting plate 1, and a sealing gasket is provided between the inner walls of the installation groove 20 to make the connection between the pipe and the pulse purging ash removal system tighter.

[0027] Example 5: The difference between this example and Example 1 is that each air outlet nozzle 7 has a short pipe 21 connected to its air inlet end. Each short pipe 21 has an external thread 22 on its surface. The surface of the air outlet ring pipe 6 has multiple threaded grooves 23 that match the external thread 22. The air outlet nozzle 7 is installed inside the threaded groove 23 through the external thread 22 on the short pipe 21, which facilitates quick installation and disassembly of the air outlet nozzle 7 and makes it easy to replace and maintain it.

[0028] Example 6: The difference between this example and Example 1 is that the connecting pipe 11 is a corrugated hose. The length of the connecting pipe 11 is long enough and the material can withstand the working temperature and pressure of the pulse soot blower, so as to facilitate the delivery of the gas from the pulse tank 9 to the air outlet nozzle 7 for spraying.

[0029] Example 7: The difference between this example and Example 1 is that each fixing plate 17 is fixedly provided with a rubber pad on its surface, and each rubber pad is provided with anti-slip texture, which makes the connection between it and the pipe more stable.

[0030] Example 8: The difference between this example and Example 1 is that, in this example, one end of the slide rod 4 is fixedly connected to a connecting plate 24, the threaded rod 2 is rotatably connected to the connecting plate 24, and a cleaning ring 25 is fixedly sleeved on the connecting plate 24. The surface of the cleaning ring 25 is provided with bristles, which can clean the inner wall of the pipe when installing and disassembling the pulse purging ash removal system.

[0031] In summary, when using this dust removal pipeline pulse purging system, the cleaning ring 25, threaded rod 2, and exhaust ring pipe 6 are inserted into the pipeline, with one end of the pipeline inserted into the mounting groove 20. Then, by rotating the screw 16 on the fixing assembly 12, the fixing plate 17 is pressed and fixed onto the pipeline, thus securing the device to the pipeline quickly and easily. Then, by controlling the solenoid valve, the gas from the pulse tank 9 is sprayed out through the connecting pipe 11 and the exhaust nozzle 7 to clean the inner wall of the pipeline. At the same time, the rotation of the drive motor 13 drives the threaded rod 2 to rotate, thereby moving the threaded sleeve 3, sliding sleeve 5, and exhaust ring pipe 6, facilitating dust removal and cleaning of different locations inside the pipeline. After cleaning is completed, the device is removed from the pipeline by rotating the screw 16 in the opposite direction, and the cleaning ring 25 and brush are used to further clean the inner wall of the pipeline.
