Description

Technical Field

[0001] The invention relates to the technical field of boilers, and in particular to a mechanical vibration and dust cleaning device for a serpentine tube heating surface. Background Art

[0002] In the field of boiler technology, ensuring the heat exchange efficiency of the serpentine tube heating surface in the boiler is the key to ensuring the normal operation of the boiler and the thermal efficiency of the boiler. For some furnace types with a certain amount of dust in the flue gas, serious dust accumulation on the serpentine tube heating surface will greatly reduce the heat exchange efficiency of the heating surface tube, thereby increasing the boiler exhaust temperature, affecting the operation of subsequent flue gas treatment equipment, and reducing the thermal efficiency of the boiler; at the same time, long-term serious dust accumulation on the serpentine tube heating surface will also increase the possibility of high-temperature corrosion of the pipeline, which will lead to a burst tube in severe cases, causing additional economic losses and a series of problems such as threats to the safety of staff, which seriously affect the safe and stable operation of the boiler.

[0003] Most of the existing serpentine tube heating surface cleaning devices are steam soot blowers and shock wave soot blowers, which have poor soot blowing effects on viscous soot. Therefore, this structure is a mechanical vibration cleaning device specifically for the serpentine tube heating surface. Summary of the invention

[0006] Preferably, the circular shock sealing device is composed of two C-shaped folded plates, which are overlapped and arranged at the place where the comb-shaped shock connecting plate passes through the membrane-type wall-wrapping tube, and the two C-shaped folded plates are respectively welded and fixed on the comb-shaped shock connecting plate and the membrane-type wall-wrapping tube.

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

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

[0009] Beneficial effects of the present invention:

[0010] The present invention has a good soot cleaning effect and can effectively remove the attached soot on the heating surface of the serpentine tube, especially for the soot attached to the serpentine tube with poor soot blowing effect and strong stickiness of some steam soot blowers and shock wave soot blowers, thereby ensuring the heat exchange effect of the heating surface of the serpentine tube and reducing the flue gas temperature at the same time, ensuring the safe and stable operation of the boiler and generating energy-saving economic benefits.

[0019] Reference Figure 1 The preferred embodiment of the present invention is a mechanical vibrating and cleaning device for the heating surface of a serpentine tube. In the boiler, the flue is divided into an inside of the flue and an outside of the flue by a membrane-type wall-wrapped tube. The mechanical vibrating and cleaning device comprises a serpentine tube 1 in the flue. The heating surface of the serpentine tube 1 is longitudinally connected by a pipe protective tile 2 and a serpentine tube connecting plate 3. The transverse tube row direction of the serpentine tube 1 is transversely connected by a comb-shaped vibrating connecting plate 4. One end of the comb-shaped vibrating connecting plate 4 is led out to the outer end of the flue and a vibrating sleeve 6 is welded thereon. A circular vibrating sealing device 7 is provided at the place where the comb-shaped vibrating connecting plate 4 passes through the membrane-type wall-wrapped tube to ensure sealing without affecting the use of mechanical vibrating.

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

[0021] In this embodiment, the circular shock sealing device 7 is composed of two C-shaped folded plates, which are overlapped and arranged at the place where the comb-shaped shock connecting plate 4 passes through the membrane-type wall-wrapping tube, and the two C-shaped folded plates are welded and fixed on the comb-shaped shock connecting plate 4 and the membrane-type wall-wrapping tube respectively.

[0022] In this embodiment, a reinforcing steel plate 5 is provided at the end of the comb-shaped shock connecting plate 4 in the flue for strengthening so as to ensure mechanical transmission.

[0023] During specific use, an external mechanical hammer strikes the shock sleeve 6 at the end of the comb-shaped shock connecting plate 4, driving the serpentine tube 1 to vibrate, causing the ash attached to the serpentine tube 1 to fall off, thereby ensuring the heat exchange 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 the present invention does not conflict with the existing conventional soot cleaning devices for the heating surface of the serpentine tube 1 - steam soot blowers and shock wave soot blowers, and can be used with steam soot blowers and shock wave soot blowers at the same time, and because of its structure, it has a better effect on the treatment of stubborn soot accumulation on the serpentine tube 1 that is difficult to handle, thereby ensuring the cleaning 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 economic benefits.

[0024] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0025] The above description is only a preferred implementation mode of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means belongs to the protection scope of the present invention.
