This project is a noise control project for the air cooler in Guangyuan Compressor Station. It mainly focuses on main and branch inlet and outlet pipes of the air cooler, inlet and outlet pipes in the process area and air intake and blow-off pipes of the air cooler. The silencers are installed for the pipelines, of which the color of the pipeline silencers is consistent with the pipeline. For the intake noise of the air cooler, an intake silencer, namely a dissipative folding plate silencer in structure, is set up; for the blow-off of the air cooler, a sound barrier should be installed around the blow-off port of the air cooler. After the governance is completed, the noise in the boundary area and at sensitive points can meet the requirements of the governance ives.
