Description

Technical Field

[0001] This utility model relates to the field of boiler technology, specifically to a boiler side water-cooled wall. Background Technology

[0002] A boiler is an energy conversion device that uses the heat energy released from combustion or other sources to heat a working fluid, such as water, to certain parameters and then provides that heat energy as an output medium. Simply put, a boiler is a device that produces steam or hot water, consisting of a steel container holding water and a combustion device. The steam produced can be used for heating or to power steam engines or turbines. Boilers require side water-cooled walls, which are the only heated surfaces in the boiler's evaporation equipment. These walls absorb heat from the high-temperature flames or flue gas in the furnace through radiative heat transfer, thus protecting the furnace walls.

[0003] Common boiler side water-cooled walls typically consist of tubes, fins, headers, and connecting pipes. Since side water-cooled walls are usually composed of a series of tubes—which can be bare tubes or membrane structures—and fins are installed on the tubes, forming an airtight structure, the fins not only increase the heat exchange area but also improve the airtightness of the furnace, reducing air leakage. The lower end of the side water-cooled wall is usually connected to a header, which is used to collect and distribute the working fluid, such as water or steam. The upper end of the side water-cooled wall can be directly connected to the boiler drum or connected to the boiler drum via a header.

[0004] In traditional boiler side water-cooled walls, incomplete combustion of fuel during fuel combustion produces combustion impurities that adhere to the tube surface. These impurities not only form an insulating layer, reducing heat transfer efficiency, but also corrode the tubes and shorten their lifespan. To address these issues, some boiler side water-cooled walls incorporate vibration equipment. This vibration causes the tubes to vibrate, separating and removing dust for cleaning. This method maintains heat transfer efficiency and extends tube lifespan. However, long-term vibration-based cleaning can lead to dust scattering and contamination, and dust can also re-adhere to the tubes. Therefore, a new boiler side water-cooled wall design is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, this utility model provides a boiler-side water-cooled wall to solve the above-mentioned technical problems that not only cause dust to scatter and fall, causing pollution to spread, but also cause dust to re-adhere to the tube body.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a boiler-side water-cooled wall, comprising:

[0009] The tube body, and the fins provided on the surface of the tube body, and the top of the tube body is connected to a top plate, and a suction fan is added to the top of the top plate, and the end of the tube body is connected to a drain pipe;

[0010] The suction cylinder is located on the front and back of the tube body, and suction holes are evenly opened on the surface of the suction cylinder. A diversion pipe is connected to the top of the suction cylinder, and the diversion pipe is connected to the suction fan. A conveying pipe is connected to the top of the suction fan.

[0011] The pump body is located at the top of the top plate and is connected to the pipe body. A vibration assembly is also installed at the top of the top plate and connected to the pipe body. The pump body delivers coolant to the inside of the pipe body, while the fins increase the heat exchange area. The coolant, after absorbing heat, is discharged to the outside through the drain pipe. The vibration assembly on the top plate drives the pipe body to vibrate. After the dust on the pipe body is separated and detached, the suction fan generates suction through the diversion duct, moving the dust along the suction cylinder, diversion duct, and conveying pipe, and transporting the dust to the inside of the external storage equipment. On the one hand, this not only prevents dust from scattering and causing pollution, but also prevents dust from re-adhering to the pipe body. On the other hand, it can transport the dust to the outside of the boiler, preventing dust from accumulating inside the boiler and affecting the combustion efficiency.

[0012] Preferably, guide posts are added to both sides of the tube body, and side connecting plates are installed on the inner side of the guide posts, with the side connecting plates connected to the tube body. The guide posts can drive the tube body to move through the side connecting plates.

[0013] Preferably, the end of the guide column is connected to the vibration assembly, and the vibration assembly includes a fixing seat located above the top of the top plate. The vibration assembly drives the pipe to vibrate on the top plate via the guide column, thereby enabling the pipe to perform a vibration cleaning operation.

[0014] Preferably, side columns are installed on both sides of the fixing base, and the side columns are connected to the top plate. A guide rod is inserted into the center of the fixing base. The side columns are fixed to the top plate, allowing the guide rod to move up and down along the fixing base.

[0015] Preferably, a connecting ring plate is mounted on the surface of the guide rod, and a composite spring is sleeved on the surface of the guide rod, with the ends of the composite spring tightly fitted to the fixed seat and the connecting ring plate respectively. The guide rod can drive the connecting ring plate to move up and down along the fixed seat, while the connecting ring plate can compress the composite spring. At the same time, the composite spring can drive the connecting ring plate and the guide rod to reset, so that the guide rod drives the tube body to vibrate.

[0016] Preferably, a cam is added to the bottom of the connecting ring plate, and a drive motor is coaxially connected to the end of the cam, with the cam rotatably connected to the top plate. The drive motor drives the cam to rotate on the top plate, causing the cam to drive the connecting ring plate and guide rod to rise along the fixed seat and compress the composite spring. When the cam rotates and separates from the connecting ring plate, the composite spring can drive the connecting ring plate and guide rod to reset, causing the guide rod to drive the tube body to vibrate.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a boiler-side water-cooled wall, which has the following beneficial effects:

[0019] The boiler's side water-cooled wall uses a pump to deliver coolant into the tubes, while fins increase the heat exchange area. The cooled liquid, having absorbed heat, is discharged outwards through a drain pipe. A vibration assembly on the top plate vibrates the tubes. After dust is separated from the tubes, a suction fan, through a distribution duct, creates suction at the suction port, moving the dust along the suction cylinder, distribution duct, and conveying pipe to the interior of an external storage device. This not only prevents dust from scattering and spreading, but also prevents dust from re-adhering to the tubes and transports it to the outside of the boiler, avoiding dust accumulation inside and its impact on combustion efficiency.

[0027] Please see Figure 2 The suction cylinder 9 is located on the front and back of the tube body 1. Suction holes 10 are evenly opened on the surface of the suction cylinder 9. A diversion pipe 8 is connected to the top of the suction cylinder 9. The diversion pipe 8 is connected to the suction fan 6. A conveying pipe 7 is connected to the top of the suction fan 6.

[0028] Pump body 5 is located on top of top plate 3 and is connected to pipe body 1. Vibration component 4 is also installed on top of top plate 3 and connected to pipe body 1. Pump body 5 delivers coolant to the interior of pipe body 1, while fins 2 increase the heat exchange area. The coolant, after absorbing heat, is discharged outwards through drain pipe 20.
