Description

Technical Field

[0001] This utility model relates to the field of boiler flue gas treatment, and in particular to a device for treating ash accumulation in the tail flue of a boiler. Background Technology

[0002] When a boiler is burning, it easily produces particulate matter that is not easily melted. These particles are discharged to the tail end of the boiler with the flue gas. As the flue gas speed slows down, they gradually accumulate in the flue. At the same time, water vapor in the flue is also easy to condense, causing dust and particles to stick to the inner wall of the flue, thus easily accumulating into ash and scale.

[0003] If the ash accumulation in the boiler tail flue is not cleaned in time, it will easily increase the flow resistance of the ash, affect the boiler's lifespan, and may also lead to safety accidents. In addition, the equipment for cleaning the ash accumulation in the boiler tail flue needs to be moved to different flue ash accumulation areas, and convenient mobile and fixed devices need to be set up. Therefore, a new solution is needed to solve this problem.

[0004] Therefore, those skilled in the art have provided a boiler tail flue ash treatment device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a boiler tail flue ash treatment device.

Inside the flue, soot is blown down from the attached pipe wall through a soot blowing pipe, and then cleaned by a scraper. The telescopic mechanism extends the cleaning range of the pipe wall, and the cleaned ash falls into the ash discharge pipe. When too much ash accumulates in the ash discharge pipe, a valve can be opened for cleaning. A fixing mechanism is also included, which secures the device to the flue pipe with a fixing sleeve. A rubber layer compresses the gap between the fixing sleeve and the flue pipe, making the fixation more stable and convenient for fixing the boiler cleaning device, facilitating rapid cleaning operations.

A connecting rod 305 is fixedly connected to both ends of the body of the air supply pipe 302. A scraper 306 is fixedly connected to the outer wall of the connecting rod 305 away from the air supply pipe 302.

[0041] The boiler tail flue ash treatment equipment is equipped with a soot blowing mechanism 3 to blow soot from the flue 1, and a telescopic mechanism 2 to extend the cleaning range. At the same time, a fixing mechanism 4 is set up to facilitate the fixing of the mechanism.

[0042] The gear frame 201 is fixedly connected to the front and rear ends of the upper surface of the base plate 401. The gear frame 201 drives the gear 202, which in turn drives the connecting column 205. The connecting column 205 drives the connecting seat 206, which in turn drives the soot blowing mechanism 3, thus expanding the cleaning range of the soot blowing mechanism 3. The air inlet pipe 301 is fixedly connected to the outer wall of one side of the connecting seat 206. The air inlet pipe 301 is connected to compressed air from an air compressor, which is then delivered to the soot blowing pipe 303 via the air delivery pipe 302, facilitating the cleaning of the flue 1. The lower surface of the base plate 401 is equipped with multiple self-locking casters 402. These casters facilitate movement of the mechanism, while the self-locking mechanism ensures its stability and safety. The outer wall of the fixed seat 403 is fixedly connected to... A fixed sleeve 404 is provided, and a fixed base 403 is provided to facilitate the fixing of the telescopic mechanism 2 and the soot blowing mechanism 3. The fixed sleeve 404 is provided to facilitate the fixing of the flue 1. A rubber layer 405 is fixedly connected to the inner wall of the fixed sleeve 404.

For areas deep within flue 1 that are difficult to clean, the device can be pushed into flue 1 using self-locking casters 402 and secured by fixing mechanism 4. The fixing sleeve 404 has a rubber layer 405 inside, which securely fixes the device to flue 1. The device takes in air through the inlet pipe 301 and delivers the gas through the gas delivery pipe 302 to the soot blowing pipe 303, where it is ejected from the soot blowing port 304 to clean the ash on flue 1. Simultaneously, motor 2 309 starts. The first bevel gear 307 rotates, which in turn drives the second bevel gear 308 to rotate. The first bevel gear 307 then drives the air supply pipe 302 to rotate, allowing the soot blowing pipe 303 to spray gas in all directions. At the same time, the scraper 306 can clean dust in all directions. After cleaning a section of dust, the telescopic mechanism 2 can be activated. The gear 202 drives the connecting column 205, which in turn drives the connecting seat 206, thereby driving the soot blowing mechanism 3 forward to expand the cleaning range. The cleaned dust will fall into the ash discharge pipe 5. When a lot of dust accumulates in the ash discharge pipe 5, the valve 6 can be opened for cleaning.
