The diaphragm acoustic soot blower operates by using airflow pressure to drive a tensioned circular diaphragm, causing the diaphragm to vibrate and generate sound waves. Compared with the rotary whistle type, its main advantage is that it eliminates the need for a motor-driven rotating mechanism. The pulsating acoustic waves act on ash deposits by subjecting them to alternating compressive and tensile forces, thereby achieving the soot-blowing effect through acoustic vibration and acoustic fatigue. Acoustic vibration helps prevent dust from adhering to the surface of ash-accumulating objects, while acoustic fatigue causes dust already attached to the surface to separate through repeated fatigue action.

Key Technical Features • Low-frequency acoustic output of 80–250 Hz, with high sound energy of 140–153 dB, providing wide soot-blowing coverage and excellent cleaning performance. • Advanced structural design with low energy consumption, long service life, and maintenance-free operation. • Sound is generated through the natural vibration of the diaphragm, ensuring high gas-to-acoustic energy conversion efficiency. • Compact structure requiring minimal space both inside and outside the furnace wall, without interfering with other operations. • Constructed from 0Cr25Ni20Si2 material, with an overall service life of up to 20 years. • Safe and reliable, compliant with applicable personnel safety, industrial hygiene, and labor protection requirements.
