The middle of the inside of the cylinder body 1 is provided with a cavity 10, the left half part of the cavity 10 is coaxially and fixedly provided with an air inlet pipe 2, the right end of the air inlet pipe 2 is closed, and the left opening is an air inlet 21. Specifically, the cylinder 1 is made of a pipeline with a model DN400, and the air inlet pipe 2 is made of a pipeline with a model DN 200. Wherein the air inlet 21 at the left end of the air inlet pipe 2 extends outwards from the cavity 10. The right end of the cylinder body 1 is provided with an exhaust port 12 communicated with the cavity 10. Flange connectors are provided at both the inlet 21 and the outlet 12. Wherein the air inlet 21 is connected to the pipe to be purged by means of a corresponding flange connection.

The side wall of the air inlet pipe 2 in the cavity 10 is provided with a plurality of air holes 20 at equal intervals, the air in the air inlet pipe 2 is uniformly discharged into the cavity 10 through the air holes 20, the air flow is uniform, and the air flow vibration is reduced, so that the noise is remarkably reduced. The specific processing method of the air holes 20 is that 8 rows of holes with the diameter of 30mm are drilled on the surface of the air inlet pipe 2 at equal intervals along the length direction.

Wherein, a plurality of baffle plates are fixedly arranged in the cavity 10 along the axis direction in an up-and-down staggered way. Drain holes 30 are formed in the bottoms of the baffles below, and a drain pipe 13 communicated with the cavity 10 is arranged below the right side of the cylinder 1.
