Description

Technical Field

[0001] This utility model relates to the field of boiler technology, and in particular to a mechanical vibration cleaning device for the heating surface of a serpentine tube. Background Technology

[0002] In the field of boiler technology, ensuring the heat exchange efficiency of the serpentine tube heating surface inside the boiler is crucial for ensuring normal boiler operation and maintaining boiler thermal efficiency. For some boiler types where the flue gas contains a certain amount of dust, severe ash accumulation on the serpentine tube heating surface will significantly reduce the heat exchange efficiency of the heating surface tubes, thereby increasing the boiler exhaust temperature, affecting the operation of subsequent flue gas treatment equipment, and also reducing boiler thermal efficiency. At the same time, long-term severe ash accumulation on the serpentine tube heating surface will also increase the possibility of high-temperature corrosion of the pipes, which may lead to tube rupture in severe cases, causing additional economic losses and threatening the safety of personnel, seriously affecting the safe and stable operation of the boiler.

[0003] Existing serpentine tube heating surface cleaning devices are mostly steam soot blowers and shock wave soot blowers, which are not very effective at blowing away highly adhesive ash. Therefore, this structure is specifically designed as a mechanical vibration cleaning device for serpentine tube heating surfaces. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems existing in the prior art and to provide a mechanical vibration dust removal device for the heated surface of a serpentine tube.

[0005] To achieve the above objectives, the technical solution provided by this utility model is: a mechanical vibration cleaning device for the heating surface of a serpentine tube. In a boiler, the flue is divided into an inner flue and an outer flue by a membrane-type wall-mounted tube. The mechanical vibration cleaning device includes a serpentine tube inside the flue. The heating surface of the serpentine tube is longitudinally connected by a pipe protector and a serpentine tube connecting plate. The transverse tube arrangement of the serpentine tube is transversely connected by a comb-shaped vibration connecting plate. One end of the comb-shaped vibration connecting plate extends to the outer end of the flue and is welded with a vibration sleeve. A U-shaped vibration sealing device is provided where the comb-shaped vibration connecting plate passes through the membrane-type wall-mounted tube.

[0006] Preferably, the U-shaped vibration sealing device consists of two C-shaped folding plates, which are arranged overlappingly at the point where the comb-shaped vibration connecting plate passes through the membrane-type wall-encasing pipe. The two C-shaped folding plates are respectively welded and fixed to the comb-shaped vibration connecting plate and the membrane-type wall-encasing pipe.

[0007] Preferably, the ends of the comb-shaped vibration connecting plate in the flue are provided with reinforcing steel plates for reinforcement.

[0008] Preferably, the vibratory sleeve is forged from a steel ingot and is connected to an external mechanical device.

[0009] The beneficial effects of this utility model are:

[0010] This invention has a good ash removal effect, effectively removing the attached ash on the heating surface of the serpentine tube. It is particularly effective for serpentine tubes with strong adhesion where steam soot blowers and shock wave soot blowers have poor soot removal effects. This ensures the heat exchange effect of the serpentine tube heating surface, while reducing the flue gas temperature, ensuring the safe and stable operation of the boiler, and generating energy-saving and economic benefits.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0018] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0019] Reference Figure 1 In a preferred embodiment of this utility model, a mechanical vibration cleaning device for the heating surface of a serpentine tube is provided. In a boiler, the flue is divided into an inner flue and an outer flue by a membrane-type wall-mounted tube. The mechanical vibration cleaning device includes a serpentine tube 1 inside the flue. The heating surface of the serpentine tube 1 is longitudinally connected by a pipe protector 2 and a serpentine tube connecting plate 3. The transverse tube arrangement of the serpentine tube 1 is transversely connected by a comb-shaped vibration connecting plate 4. One end of the comb-shaped vibration connecting plate 4 extends to the outer end of the flue and is welded with a vibration sleeve 6. A U-shaped vibration sealing device 7 is provided where the comb-shaped vibration connecting plate 4 passes through the membrane-type wall-mounted tube to ensure sealing without affecting the use of mechanical vibration.

[0020] Furthermore, the vibrating sleeve 6 is forged from steel ingots, and the vibrating sleeve 6 is connected to an external mechanical device.

[0021] In this embodiment, the U-shaped vibration sealing device 7 consists of two C-shaped folding plates. The two C-shaped folding plates are arranged overlappingly at the point where the comb-shaped vibration connecting plate 4 passes through the membrane-type wall-wrapping pipe, and the two C-shaped folding plates are respectively welded and fixed to the comb-shaped vibration connecting plate 4 and the membrane-type wall-wrapping pipe.

[0022] In this embodiment, the end of the comb-shaped vibration connecting plate 4 in the flue is provided with a reinforcing steel plate 5 for reinforcement to ensure mechanical transmission.

[0023] In practical use, the external mechanical vibratory hammer strikes the vibratory sleeve 6 at the end of the comb-shaped vibratory connecting plate 4, causing the serpentine tube 1 to vibrate, thus causing the furnace ash attached to the serpentine tube 1 to fall off, ensuring the heat exchange effect of the serpentine tube 1 heating surface, while reducing the flue gas temperature and ensuring the safe and stable operation of the boiler. Furthermore, this utility model does not conflict with the existing conventional ash removal devices for the heating surface of the serpentine tube 1 - steam soot blowers and shock wave soot blowers - and can be used simultaneously with steam soot blowers and shock wave soot blowers. Due to its structural design, it is more effective in treating stubborn ash accumulation on the serpentine tube 1, which is difficult to handle, ensuring the ash removal effect of the heating surface of the serpentine tube 1, while reducing the flue gas temperature, ensuring the safe and stable operation of the boiler, and generating energy-saving and economic benefits.

[0024] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.

[0025] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
