    摘要： A pipeline (180) provided with a silencing structure, the pipeline comprising a pipe (150) and a silencing structure (100). The pipe (150) has a uniform diameter. The silencing structure (100) comprises a main silencing pipe (210) and a baffle (220). The baffle (220) is disposed around the main silencing pipe (210) and is connected on the main silencing pipe (210), and the baffle (220) comprises an opposite first side and second side; the main silencing pipe (210) extends on the first side and/or the second side of the baffle (220); the main silencing pipe (210) of the silencing structure (100) is disposed in the pipe (150) and is connected to the pipe (150) by means of the baffle (220); and the baffle (220) is configured to be capable of stopping a fluid from flowing through the baffle (220) from the space between the pipe (150) and the main silencing pipe (210).
