[0002] In industries such as light industry, chemical industry, petrochemical industry, coal chemical industry, and fine chemical industry, compressed air, nitrogen, oxygen, chemical plant synthesis gas, and mixed gas are used. Under the premise of high flow rate and high noise reduction of gas passing through gas pipelines and fan pipelines, pipeline silencers are installed on the pipelines to reduce low-frequency noise below 500Hz in the pipelines.

[0003] Currently, existing pipeline silencers with high flow rates and high noise reduction capacity will exhibit noise phenomena due to gas noise and airflow vibration below 500Hz, thus affecting the noise reduction effect. Utility Model Content
