介绍了高温高压水通过二次节流气液扩容分离和小孔变频扩散等多种方法 ,使排放时高达 15 0dB的噪声降到 5 0dB以下。
Introduced a variety of methods of high temperature and pressure water through secondary throttling gas and liquid expansion and separation and small hole frequency conversion and diffusion, so that emissions up to 15 0dB noise dropped below 50dB.
