Abstract:
1. An oil mist separator for separating aerosol oil from an oil-laden gas, the oil mist separator comprising: an impactor; the impactor comprising a nozzle device with at least one nozzle for gas to be freed from oil, wherein the at least one nozzle has a streaming region; the impactor further comprising at least one deflector body having a separating region for the oil, wherein the separating region is positioned in the streaming region of the at least one nozzle; wherein the separating region has a surface structure that is monolithically formed with the at least one deflector body; wherein the surface structure comprises elevations and recesses arranged alternatingly in all directions transversely to a main streaming direction of the at least one nozzle; wherein the surface structure has a series adjacently arranged projecting structural bodies, each having a corresponding center line extending in its direction of projection; wherein the projecting structural bodies are arranged on the surface structure in spaced apart rows and columns forming spaced apart rows and columns of elevations, the rows aligned in a first direction traverse to a main streaming direction of the at least one nozzle, the columns aligned on a second direction traverse to the main streaming direction of the at least one nozzle and also traverse to the first direction; wherein the corresponding center line extending in the direction of projection of the projecting structural bodies is aligned with the main streaming direction of the at least one nozzle; wherein the rows and columns of projecting structural bodies form a first set of spaced recesses elongated along the first direction and a second set of spaced recessed elongated along the second direction; wherein distances between corresponding center lines of adjacent structural bodies on each row and column is less than or equal to a diameter of a nozzle opening of the at least one nozzle.
