[0022] The gas inside the equipment body 1 is initially silenced by the connecting device and then introduced into the gas duct 2.

The support device dampens the gas duct 2, the buffer device buffers the gas duct 2, and the vibration damping device dampens the equipment body 1. By setting up this device, not only can the gas be silenced and reduced in noise multiple times, but the vibration of the equipment body 1 and the gas duct 2 can also be reduced, thus improving the overall noise reduction effect of the equipment body 1.

[0037] This utility model discloses a novel noise reduction device for mechanical equipment. During operation, gas inside the equipment body 1 is first introduced into the air guide pipe 2 through a metal corrugated pipe 7, reducing noise transmission caused by vibration. Then, after being absorbed by multiple sets of sound-absorbing plates 8, the gas is dispersed through multiple sets of main air pipes 10 and multiple sets of branch air pipes 11 before being introduced into a curved manifold 12. The curved manifold 12 reduces sound energy by changing the propagation path and speed of sound waves. The gas is then discharged through the curved manifold 12. When the air guide pipe 2 vibrates, four sets of second fixing rods 14... The four sets of first fixed rods 13 slide within each other, while the four sets of second springs 16 undergo elastic deformation. The four sets of guide rods 17 slide within the grooves of the four sets of first fixed rods 13. The four sets of second springs 16 dampen the air duct 2.
