1. An oil-water separation device, comprising:
a housing;
a plurality of longitudinal plate members, each longitudinal plate member is inclined relative to a horizontal direction and arranged along a longitudinal direction of the housing, which forms one flow channel in an inner chamber of the housing;
a first guiding hole, provided on each longitudinal plate member, which is in communication with the flow channel;
a second guiding hole, provided between each longitudinal plate member and the inner wall of the housing, which is in communication with the flow channel and has a geometric position lower than that of the first guiding hole; and
a collection pipe, arranged at a longitudinal downstream end of the housing, which is in communication with the inner chamber of the housing through a top wall of the housing,
wherein each longitudinal plate member comprises a pair of profiled plates arranged opposite to each other with an interval therebetween, each profiled plate is obliquely arranged, having an inner end higher than an outer end thereof, and
each profiled plate includes a profiled head part, a profiled middle part and a profiled tail part that are connected with each other in sequence in a direction from the inner end to the outer end,
wherein the first guiding hole is formed between the profiled head parts of said two profiled plates, and the second guiding hole is formed between the profiled tail parts and the inner wall of the housing,
wherein the plurality of longitudinal plate members are positioned one above another in the inner chamber of the housing along a vertical direction, the plurality of first guiding holes of the plurality of longitudinal plate members being in through communication with each other, and
each longitudinal plate member has a first angle formed by a line connecting two ends of the profiled head part and the horizontal direction, and in any of two adjacent longitudinal plate members, the first angle of the longitudinal plate member located above is larger than the first angle of the longitudinal plate member located below.
