Abstract

The invention discloses a gas-sound complex field uniform-distribution device and a uniform-distribution method thereof. The uniform-distribution device comprises a device inlet, a gas-sound field uniform-distribution space, sound production devices and a device outlet. A gas inlet plate is arranged on the device inlet. A gas-sound flow guide plate is arranged on the device outlet. The gas-sound field uniform-distribution space is a space defined by the air inlet plate, the gas-sound flow guide plate and a space wall between the air inlet plate and the gas-sound flow guide plate. The sound production devices are arranged in the gas-sound field uniform-distribution space. By means of the gas-sound complex field uniform-distribution device and the uniform-distribution method, uniform distribution of gas-sound complex matter energy flow fields is achieved, and the complex flow field uniform-distribution degree is promoted to be increased through the interaction effect among different matter energy fields; the device is compact in structure, the method is easy to implement, gas-sound complex field uniform-distribution can be achieved in real sense, and the device and the method have an important significance in energy saving and environment protection and has the popularization value.

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...
