When selecting the muffler of the dust collector equipment, the following points should be paid attention to:
1: When the dust collector is selected, the first step should be the noise level, characteristics, corporate noise, environmental standards, equipment size standards, and background noise of the fan to determine the amount of noise reduction required.
消声器应该在比较宽的频率范围之内有比较高的消声量。 2: The muffler should have a relatively high amount of noise within a relatively wide frequency range. 除尘器设备可采用扩散式的消声器，相对有消除以高、中、小频为首的噪音，可选采带有阻性的消声器；相对于消除很宽、频噪声，可采取阻抗复合式消声器。 Can remove the noise led by the intermediate frequency, the dust collector equipment can use the diffuse muffler, relatively eliminate the noise led by the high, medium and small frequency, can choose to use a resistive muffler. , Can adopt impedance composite muffler.
当噪声通过消声器的时候，气体中含有水份或含粉尘量比较多时，出现这种情况下，不宜选用采用事家阻性消声器。 3: When the noise passes through the muffler, the gas contains more water or dust, so in this case, it is not suitable to use a house-resisting muffler.
4 :: The muffler of the dust removal equipment should be as small as possible, not complicated in structure, simple and easy to maintain, low cost performance, long use limit, and low resistance when passing gas.
当气体经过消声器的通道时，风速大小一般控制在 5～20m ／ s 的范围之内，以防止产生第二次噪声。 5: When the gas passes through the passage of the muffler, the wind speed is generally controlled within the range of 5-20m / s to prevent the second noise.
6: The air volume specified by the dust removal equipment factory when selecting the muffler should not be less than the actual air volume when the fan is started.
