This application discloses an oil-gas separator, including a cylinder with an inlet end and an outlet end; and at least one reinforcing ring fixedly sleeved on the outer peripheral wall of the cylinder. The reinforcing ring is configured to increase the local stiffness of the cylinder, thereby adjusting the overall modal frequency of the cylinder to above a preset threshold, so that the natural frequency of the cylinder avoids the excitation frequency of the compressor. This application eliminates resonance noise by setting a reinforcing ring on the outer periphery of the cylinder and utilizing the principle of passive structural control. The reinforcing ring significantly increases the local stiffness of the shell, forcing the overall modal frequency of the oil-gas separator to jump above the main excitation frequency band of the compressor, thus cutting off the physical conditions for resonance at its source and overcoming the defect of low absorption efficiency of traditional sound-absorbing cotton for low-frequency vibration. This solution directly modulates the noise radiation source mechanically, effectively suppressing the sound radiation efficiency of the shell. At the same time, the optimized structural parameters eliminate the planar modal resonance of the additional structure itself, achieving substantial improvement in noise across the entire frequency band.
