Abstract: An oil-water mixture treatment device has a laminar separator and an electric field separator. The laminar separator has a coalescing tube with coalescing filler provided therein, a separating tube arranged above the coalescing tube, and a discharging tube arranged above the separating tube. The coalescing tube is connected to said separating tube by a first connecting tube group and the separating tube is connected to the discharging tube by a second connecting tube group. The oil-water mixture to be treated enters, after being treated in the coalescing tube, the separating tube through the first connecting tube group for laminar separation. The resulting oil phase enters the discharging tube through the second connecting tube group and then is discharged through an oil discharge pipeline, while the resulting water phase enters the electric field separator from a lower portion of the separating tube for a next stage of separation.

Abstract: An oil-water separation apparatus has a housing that contains at least one longitudinal plate member arranged in a longitudinal direction of the housing (10) and inclined relative to a horizontal direction. The longitudinal plate member forms at least one fluid channel in an inner chamber of the housing. A first guiding hole is provided on the longitudinal plate member or between the longitudinal plate member and an inner wall of the housing, and is in communication with the fluid channel. A second guiding hole is provided on the longitudinal plate member or between the longitudinal plate member and the inner wall of the housing, and is in communication with the fluid channel and is placed lower than the first guiding hole is positioned. A collection pipe is arranged at a longitudinal downstream end of the housing, and is in communication with the inner chamber of the housing.

Abstract: Disclosed herewith a separation device for performing phase separation on a three-phase liquid. The device includes: a housing; at least one pair of longitudinal baffle plates; a flow channel formed between every pair of longitudinal baffle plates; and collection chambers formed between adjacent pairs of longitudinal baffle plates. Each collection chamber is provided with a transverse baffle plate to separate the collection chamber into a first phase and a second phase collection cells. Each flow channel is provided with multiple lateral baffle plates to separate the flow channel into multiple sub-channels. In the areas of each longitudinal baffle plate where the first phase and second phase collection cells are located respectively, said longitudinal baffle plate is provided with a first and a second phase guiding holes in communication with the first phase and the second collection cells respectively.
