The invention discloses a high-precision rotary valve type acoustic wave generator designed for acoustic wave sootblowers, and provides the acoustic wave generator which converts airflow from an alternating current state to a direct current state and generates low-frequency acoustic waves through cutting compressed air or steam and repeatedly opening and closing an airflow nozzle. According to the high-precision rotary valve type acoustic wave generator, particularly, the high-precision design of a clearance between a rotor and a stator is achieved inside a valve body, the high-efficiency conversion of the acoustic waves is achieved, the leakage of the acoustic waves is reduced, the problem that the acoustic wave generator is low in efficiency and high in noise is solved, the amount of steam required by generation of the same amount of acoustic waves is smaller, the steam cost is reduced, the device is simple in structure and convenient to mount, the mounting position can be adjusted according to the environment, and the acoustic wave generator is applicable to various working occasions of boiler sootblowers.
Description
technical field [0001] The invention relates to a rotary valve type sound wave generator, in particular to a high precision rotary valve type sound wave generator used for a boiler soot blower. Background technique [0002] The basic principle of sonic soot blowing is to use the repeated action of sound wave vibration to apply a load that changes in tension and compression cycles on coke slag or ash particles. The scour of the upper flue gas flow and the impact of the particles in the flue gas will fall off. Sonic soot blowing technology uses a sound generator to modulate high-pressure airflow to generate strong sound waves. Due to the omnidirectional propagation of sound waves and high-speed periodic oscillation of air particles, it can destroy and prevent the combination of dust particles on the surface of the heat exchange surface or between particles. The dust particles on the furnace wall and pipes are separated from the heat exchange surface and suspended, and then ta...
