Description

Technical Field

[0001] This utility model belongs to the field of flue gas duct cleaning technology, specifically relating to a flue gas duct unblocking device. Background Technology

[0002] During waste incineration at waste-to-energy plants, dry ash easily accumulates in the pipes between the boiler outlet and the dust collector, forming a thick, hard shell. To prevent blockage, this thick shell needs to be cleaned. High-pressure water flushing is often used to remove this deposit. However, since the inner walls of flue gas pipes are typically lined with glass flakes, rubber, or FRP (fiberglass reinforced plastic) corrosion-resistant layers, high-pressure water may directly erode these layers during vertical flushing, causing localized peeling and cracking. This can lead to corrosion and perforation of the pipe body during subsequent operation, affecting its use. Furthermore, the wastewater and sludge that accumulate downwards during flushing may cause secondary blockages, reducing the efficiency of pipe cleaning. Utility Model Content

[0003] This utility model provides a cleaning device for flue gas ducts, which can reduce the impact of vertical impact on the inside of the flue gas duct, reduce the damage of high-pressure water flow to the corrosion layer of the duct when using high-pressure water to flush the flue gas duct, and at the same time prevent liquid from splashing outwards and reacting chemically with the surrounding gases to form new deposits that adhere to the pipe wall, and prevent the falling waste liquid and fixed at the bottom of the pipe from forming secondary blockages, thus helping to improve the efficiency of cleaning work.

[0004] This utility model provides the following technical solution: a flue gas duct unblocking device, comprising a high-pressure water gun body, a first connecting pipe fixedly connected to the end of the high-pressure water gun body, and a second connecting pipe hinged to one end of the first connecting pipe via a hinged connecting shaft, a water supply pipe fixedly connected to the end of the high-pressure water gun body, and the water supply pipe sequentially passing through the first connecting pipe and the second connecting pipe, a fan-shaped nozzle fixedly connected to the end of the water supply pipe, a telescopic connecting rod fixedly connected to the top of the second connecting pipe, a connecting seat provided on one side of the telescopic connecting rod, and the connecting seat fixedly connected to the outside of the second connecting pipe, a traction rope fixedly connected to one side of the connecting seat, and a traction rod fixedly connected to one end of the traction rope, a mounting base fixedly connected to the outside of the high-pressure water gun body, a protective cover fixedly connected to one side of the mounting base, an arc-shaped baffle fixedly connected to one side of the protective cover, a collecting air bladder provided at the bottom of the protective cover, and a connecting pipe fixedly connected to the top of the collecting air bladder, the connecting pipe communicating with the inside of the protective cover.

[0005] Both the first connecting pipe and the second connecting pipe have through grooves inside, and the water supply pipe is located inside the through grooves.

[0006] The hinged connecting shaft has a through hole inside, and one end of the water supply pipe extends through the through hole into the interior of the second connecting pipe.

[0007] The outer end of the telescopic connecting rod is fixedly connected with a rubber head.

[0008] One end of the traction rod passes through the mounting base and extends to the outside of the mounting base, and a pull ring is fixedly connected to the outer end of the traction rod.

[0009] The inner side of the protective cover is fixedly connected with absorbent cotton.

[0010] The outer plug of the collecting airbag is equipped with a drain plug.

[0011] The beneficial effects of this utility model are as follows: With the coordinated action of the inclined fan-shaped nozzle and the telescopic connecting rod, the tangential force generated by the downward spray of water jets peels away blockages, rather than impacting the corrosion layer surface vertically. This reduces the impact of vertical impacts on the inside of the flue gas duct and minimizes damage to the corrosion layer caused by high-pressure water flow when flushing the flue gas duct. Simultaneously, the protective cover, arc-shaped baffle, air collection bag, and connecting pipe work together to form a splash-proof protective assembly. This prevents the liquid from splashing outwards during cleaning of the pipe wall and reacting chemically with the surrounding environment to form new deposits. It also intercepts the liquid flushed down by the fan-shaped nozzle, causing waste liquid and flushed objects to fall inside the protective cover, preventing secondary blockages caused by the falling waste liquid or objects fixed at the bottom of the pipe. This helps improve the efficiency of the cleaning work.

[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0017] Please see Figures 1-3 This utility model provides the following technical solution: a flue gas duct unblocking device, comprising a high-pressure water gun body 1, a first connecting pipe 2 fixedly connected to the end of the high-pressure water gun body 1, and a second connecting pipe 21 hinged to one end of the first connecting pipe 2 via a hinged connecting shaft 22; a water supply pipe 24 fixedly connected to the end of the high-pressure water gun body 1, and the water supply pipe 24 sequentially passing through the first connecting pipe 2 and the second connecting pipe 21; a fan-shaped nozzle 25 fixedly connected to the end of the water supply pipe 24; and a telescopic connecting rod 26 fixedly connected to the top of the second connecting pipe 21. A connecting seat 3 is provided on one side of 26, and the connecting seat 3 is fixedly connected to the outside of the second connecting pipe 21. A traction rope 31 is fixedly connected to one side of the connecting seat 3, and a traction rod 32 is fixedly connected to one end of the traction rope 31. A mounting seat 41 is fixedly connected to the outside of the high-pressure water gun body 1, and a protective cover 4 is fixedly connected to one side of the mounting seat 41. An arc-shaped baffle 5 is fixedly connected to one side of the protective cover 4. A collecting air bag 51 is provided at the bottom of the protective cover 4, and a connecting pipe 52 is fixedly connected to the top of the collecting air bag 51. The connecting pipe 52 is connected to the inside of the protective cover 4.

[0018] In this implementation scheme: the high-pressure water gun body 1 provides high pressure for the sprayed water flow. The first connecting pipe 2, located at the end of the high-pressure water gun body 1, forms an installation assembly for installing the water supply pipe 24 through the cooperation of the second connecting pipe 21 and the hinged connecting shaft 22. This assembly provides an environment for the installation of the water supply pipe 24, which is used to transport water. The first connecting pipe 2 and the second connecting pipe 21 are connected by a hinge, allowing the angle of the second connecting pipe 21 to be adjusted. This adjustment of the angle of the fan-shaped nozzle 25 during the cleaning of the flue gas duct expands the cleaning range of the duct, thus aiding in... To reduce blind spots during flue gas duct cleaning, the fan-shaped nozzle 25 is angled to utilize the tangential force generated by the downward water jet to peel away blockages, rather than impacting the corrosion layer surface vertically. This reduces the impact of vertical impacts on the flue gas duct interior and minimizes damage to the corrosion layer caused by high-pressure water flow during flue gas duct flushing. The telescopic connecting rod 26 at the top of the second connecting pipe 21 limits the distance between the entire device and the inner wall of the duct, preventing the fan-shaped nozzle 25 from being too close to the inner wall. The telescopic connecting rod 26 also ensures that the fan-shaped nozzle 25 remains in contact with the duct during flushing. Maintaining a uniform distance between the inner walls of the pipes helps improve the uniformity of cleaning effort inside the pipes. The connecting seat 3 on the second connecting pipe 21, in conjunction with the traction rope 31 and the traction rod 32, forms an adjustment assembly for adjusting the angle of the second connecting pipe 21 and the fan-shaped nozzle 25. When the angle of the fan-shaped nozzle 25 needs adjustment, the traction rod 32 can be pulled outwards, causing the end of the traction rope 31 to move outwards. This lifts the second connecting pipe 21 upwards, thereby lifting the fan-shaped nozzle 25 upwards, completing the angle adjustment. The protective cover 4, in conjunction with the mounting base 41, forms a splash-proof protective assembly, preventing the fan-shaped nozzle from being sprayed. When the nozzle 25 cleans the pipe wall, the liquid splashes outward and reacts chemically with the surrounding gas to form new deposits that adhere to the pipe wall. The arc-shaped baffle 5 located on one side of the protective cover 4 intercepts the liquid flushed down by the fan-shaped nozzle 25, causing the waste liquid and flushed objects to fall inside the protective cover 4. This prevents the falling waste liquid and objects fixed at the bottom of the pipe from causing secondary blockages. During use, one side of the arc-shaped baffle 5 is in contact with the pipe wall. The collecting airbag 51 provides a temporary storage space for the flushed waste liquid and solids. The connecting pipe 52 provides a connecting medium between the collecting airbag 51 and the arc-shaped baffle 5.

[0019] Both the first connecting pipe 2 and the second connecting pipe 21 have through grooves 23 inside, and the water supply pipe 24 is located inside the through grooves 23. The hinged connecting shaft 22 has through holes 221 inside, and one end of the water supply pipe 24 extends into the interior of the second connecting pipe 21 through the through holes 221. The through grooves 23 and through holes 221 are used to provide space for the water supply pipe 24 to pass through.

[0020] A rubber head 261 is fixedly connected to the outer end of the telescopic connecting rod 26; the rubber head 261 is used to provide a soft contact surface between the end of the telescopic connecting rod 26 and the pipe wall, and when the telescopic connecting rod 26 is in an inclined state, the softness of the rubber head 261 can be used to make the telescopic connecting rod 26 fit against the pipe wall.

[0021] One end of the traction rod 32 passes through the mounting base 41 and extends to the outside of the mounting base 41, and a pull ring 33 is fixedly connected to the outer end of the traction rod 32; wherein the pull ring 33 is used to provide the worker with a pull object to pull the traction rod 32.

[0022] An absorbent cotton 42 is fixedly connected to the inside of the protective cover 4; the absorbent cotton 42 is used to absorb the small water mist inside.

[0023] The outer plug of the collecting airbag 51 is equipped with a drain plug 53; when it is necessary to clean the waste liquid in the collecting airbag 51, the drain plug 53 can be removed from the collecting airbag 51 and the liquid in the collecting airbag 51 can be poured out to the outside.

[0024] The working principle and usage process of this utility model are as follows: When it is necessary to clean the flue gas duct, first connect the pipe at the end of the high-pressure water gun body 1 to the water source, and then turn on the high-pressure water gun body 1. At this time, the fan-shaped nozzle 25 can clean the duct. During the cleaning process, the absorbent cotton 42 can absorb the small water mist sprayed inside, and the protective cover 4 can isolate and protect the surrounding area. During the cleaning process, the sewage and fallen dirt fall into the inner side of the protective cover 4 and enter the collection air bag 51 through the connecting pipe 52 to complete the interception and collection of sewage. In addition, after adjusting the angle of the fan-shaped nozzle 25, the length of the telescopic connecting rod 26 is adjusted so that the rubber head 261 can be aligned with the outer wall of the arc-shaped baffle 5.
