[0041] The conduit 8 is trumpet-shaped, the output end of the sound wave sounding head 6 is fixedly connected to the small end of the conduit 8, the other end of the conduit 8 is clamped with the installation support component and the diameter becomes larger as it is farther away from the sound wave sounding head 6, the installation support component is embedded in the wall 9, the open part of the installation support component is fixedly provided with an installation adjustment component 7, and the middle part of the installation adjustment component 7 is provided with a limiting hole adapted to the outer diameter of the conduit 8.

[0046] Working principle of the utility model: Convert compressed air into high-power sound waves or infrasonic waves, and the sound waves or infrasonic waves propagate in the space medium in the form of compression and rarefaction waves, acting on the ash accumulation surface in the space. Specifically, the utility model uses compressed air as the power source, and generates high-intensity sound waves or infrasonic waves through specific devices (such as the sound wave generator head 6 and the conduit 8). The generated sound waves or infrasonic waves are sent into the space area in the space where ash may accumulate. Through the repeated pulling and pressing actions of the sound waves, the ash accumulation on the heated surface is affected by vibration and resonance. This vibration and resonance effect causes the ash particles to vibrate reciprocally, thereby breaking the combination between the dust and the heat exchange surface, making the ash accumulation fall off due to vibration or be in a suspended state. These vibrated ash particles are carried away under the action of the flue gas flow, or fall off by themselves due to gravity, so as to achieve the purpose of removing ash accumulation and preventing ash accumulation.

[0047] The above has made a detailed description of the implementation manner of the utility model. However, the utility model is not limited to the above implementation manner, and various changes can be made without departing from the purpose of the utility model within the scope of knowledge possessed by those of ordinary skill in the art.
