在合成氨生产及氨加工的工艺过程中,由于操作和开停车等需要,有时必须将大量的工艺气体放空。这些气体及不同的压力排空时会产生强大的空气动力学噪声。氨厂的每一个放空管即是一个噪声源,产生的噪声一般均属宽频带,而且影响范围也比较广。为了有效地治理氨厂放空噪声,我们对噪声 Ammonia production and ammonia processing in the process, due to the need to operate and open the car, and sometimes must be a large number of process gas venting. These gases and different pressures evacuate to produce strong aerodynamic noise. Each exhaust pipe of the ammonia plant is a noise source, and the noise generated is generally in a wide frequency band, and the influence range is relatively wide. In order to effectively manage the ammonia plant venting noise, we have the noise
