Description

Technical Field

[0001] This utility model belongs to the field of acoustic ash removal technology, specifically relating to a magnetic superimposed acoustic ash blower. Background Art

[0002] Existing acoustic sootblower technology uses a specific structure to emit sound waves that are then directed into the enclosed space to be cleaned, thus performing the cleaning function. The mechanism of acoustic cleaning is to use the energy of the sound waves to vibrate dust particles, causing them to bounce and suspend, thus detaching them from the surface where dirt has accumulated. The greater the sound wave energy, the stronger the cleaning effect. However, currently available acoustic sootblowers have limitations in the upgrading of the sound waves they produce, and the sound wave energy is not ideal, resulting in poor dust removal efficiency. Therefore, a magnetic superposition frequency acoustic sootblower is needed to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a magnetic superposition acoustic soot blower to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a magnetic superposition frequency acoustic soot blower, comprising a shell, a first sealing cover and a second sealing cover respectively connected to the top and bottom of the shell, an air inlet pipe connected to the top of the first sealing cover, a sealing assembly connected inside the second sealing cover, a rotating component provided inside the sealing assembly, an exhaust component provided inside the rotating component, a support pipe snapped into the second sealing cover, the top end of the support pipe connected to a motor through a connecting sleeve, the output shaft of the motor connected to the rotating component, a bearing sleeved on the rotating component, the bearing snapped into the support pipe, and two conduits snapped into the shell;

[0005] The sealing assembly includes a sealing tube with air inlets on both sides. The exhaust assembly includes an exhaust pipe with a through hole and an exhaust hole inside. The through hole and the exhaust hole are connected. The rotating component includes a rotating tube with several generating holes on its outer side.

[0006] When the soot blower generates sound waves for ash removal, the sound waves will not cause stress damage to the furnace tubes, supports and other components. The high sound pressure level is greater than or equal to 160dB. By adjusting the frequency and changing its wavelength, the repeated tension and compression of the dense and sparse waves can be achieved. The omnidirectional propagation and high-speed periodic oscillation of air particles can cause the ash particles on the surface to detach from the substrate and be in a suspended state so that they can be carried away by the flue gas flow.

[0007] As a preferred embodiment, the sealing tube is connected to the outer shell and the second sealing cover, and the rotating tube is sleeved inside the sealing tube.

[0008] As a preferred embodiment, the exhaust pipe is fitted inside the rotating pipe.

[0009] As a preferred embodiment, the air intake pipe is connected to a first sealing cover, and the first sealing cover is connected to a second sealing cover via two conduits.

[0010] As a preferred embodiment, the second sealing cover is connected to two air inlets, which are connected to a through-hole via a generating hole, and the through-hole is connected to an exhaust hole.

[0011] As a preferred embodiment, the rotating tube is disposed inside the supporting tube, and the bearing is snapped onto the outside of the rotating tube.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention comprises a motor, a rotating pipe, an exhaust pipe, a through hole, an air inlet, a conduit, and an exhaust port. The motor is controlled to operate, and the rotating pipe drives several generating holes on its outer side to rotate. Simultaneously, gas is introduced into the first sealing cover through the air inlet pipe. The gas entering the first sealing cover flows into the second sealing cover through two conduits. The gas flowing into the second sealing cover intermittently enters the rotating generating holes through two air inlets, allowing for a dual-inlet, dual-outlet gas flow. This method can superimpose sound wave waveforms of the same frequency to generate a loud sound with high energy. By controlling the speed of the rotating pipe driven by the motor, the frequency and wavelength of the sound waves generated by the rotating generating holes are altered, achieving repeated tension and compression of dense and sparse waves. The generated sound waves exhibit radiation, diffraction, and reflection characteristics. When fly ash is subjected to repeated tension and compression of dense and sparse waves at a certain frequency, it becomes fatigued, loosens, and falls off, carried away by the flue gas flow. The axial blowing distance can reach 18m, demonstrating excellent dust removal efficiency. Attached Figure Description

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the embodiments.

The conditions in the examples may be further adjusted according to specific conditions. Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-5 This utility model provides a magnetic superimposed frequency acoustic soot blower, including a shell 1. The top and bottom of the shell 1 are respectively connected to a first sealing cover 2 and a second sealing cover 4. The top of the first sealing cover 2 is connected to an air inlet pipe 3. The second sealing cover 4 is connected to a sealing assembly 5. The sealing assembly 5 is provided with a rotating part 7. The rotating part 7 is provided with an exhaust assembly 6. A support pipe 8 is snapped into the second sealing cover 4. The top end of the support pipe 8 is connected to a motor 10 through a connecting sleeve 9. By setting the connecting sleeve 9, the motor 10 can be connected to the support pipe 8 together. The motor 10 is a permanent magnet motor 10.

[0023] The output shaft of the motor 10 is connected to the rotating part 7. The rotating part 7 is fitted with a bearing 11, which is snapped into the support tube 8. Two conduits 12 are snapped into the outer shell 1. By setting the bearing 11, the rotating tube 71 can be limited and fixed in the support tube 8.

[0024] The sealing assembly 5 includes a sealing tube 51, with air inlets 52 on both sides of the sealing tube 51. The exhaust assembly 6 includes an exhaust pipe 61, with a through hole 62 and an exhaust hole 63 inside the exhaust pipe 61. The through hole 62 is connected to the exhaust hole 63. The rotating component 7 includes a rotating tube 71, with several generating holes 72 on the outside of the rotating tube 71. The sealing tube 51 is connected to the outer shell 1 and the second sealing cover 4. The rotating tube 71 is sleeved inside the sealing tube 51. The exhaust pipe 61 is sleeved inside the rotating tube 71. The air inlet pipe 3 is connected to the first sealing cover 2. The first sealing cover 2 is connected to the second sealing cover 4 through two conduits 12. The second sealing cover 4 is connected to two air inlets 52. The air inlets 52 are connected to the through holes 62 through the generating holes 72. The through holes 62 are connected to the exhaust holes 63. The rotating tube 71 is located inside the support tube 8. The bearing 11 is snapped onto the outside of the rotating tube 71.

[0025] This magnetic superposition frequency acoustic soot blower is driven by a permanent magnet motor 10. The motor 10 is equipped with a power amplifier to continuously cut the high-speed airflow in the acoustic generator to generate sound waves. The air source of the magnetic superposition frequency acoustic soot blower adopts a dual-inlet and dual-outlet method. The sound wave waveforms of the same frequency are superimposed. According to the sound superposition theory, the superposition of two sound waves with equal sound pressure levels is equivalent to doubling the energy, that is, the sound pressure level increases by 3dB. The sound pressure level is significantly increased. The adjustable range of the acoustic generator can adapt to the frequency range of various types of ash accumulation. When the sound pressure level is ≥163dB, the sound power is ≥50000W, and the frequency adjustment range reaches 20-8000HZ, the soot blowing effect is significantly increased.

[0026] The working principle and usage process of this utility model are as follows: When the soot blower needs to be used, the control motor 10 is activated. The activated motor 10 drives the rotating tube 71 to rotate within the bearing 11. The rotating tube 71 drives several generating holes 72 on its outer side to rotate. At the same time, gas is introduced into the first sealing cover 2 through the air inlet pipe 3. The gas introduced into the first sealing cover 2 flows into the second sealing cover 4 through two conduits 12. The gas flowing into the second sealing cover 4 enters the rotating generating holes 72 intermittently through two air inlet holes 52. The gas flowing into the generating holes 72 is discharged from the exhaust hole 63 through the through hole 62.
