The invention relates to an oil scavenging apparatus, in particular to an oil suction roll. The oil suction roll comprises a support body, a first oil suction layer, a second oil suction layer, a first surface layer and a second surface layer, which are integrated as a whole by sewing or pressing. The support body is of a network structure made from a soft flexible and foldable material, the firstoil suction layer is arranged on one side of the support body, the second oil suction layer is arranged on the other side of the support body, the first surface layer covers on the surface which is not bonded with the support body of the first oil suction layer, the second surface layer covers on the surface of which is not bonded with the support body of the second oil suction layer. The first and second suction layers are formed by conducting needle punching to webs formed by warp-inlaid weaving or warp and weft-inlaid weaving of filaments formed by oil-absorbing polymer fibers and heat-bonding fibers. The surface layers are of fine polypropylene fiber meltblown layers. The oil suction roll is capable of floating on water surface for a long time so as to improve the oil suction efficiency.
