Description

technical field [0001] The invention relates to an aeroacoustic composite field uniform distribution device and a uniform distribution method thereof, which are used in related fields such as ash removal of coal-fired boilers in industries such as electric power and metallurgy. Background technique [0002] Both sound waves and gas are a kind of energy, and the uniform arrangement of the gas-acoustic composite field plays an important role in the ash removal of coal-fired boilers, which is of great significance for energy saving and environmental protection. [0003] In the prior art, uniform airflow distribution can be achieved to a certain extent by providing an airflow uniform distribution plate with a certain perforation rate. However, the uniform airflow distribution plate generally adopts a single-layer arrangement, because it is difficult to determine the optimum opening ratio and the optimum hole shape, so it is difficult to achieve the ideal airflow uniformity effec...
