Detailed Description
The present invention will be described in further detail with reference to the following detailed description and the accompanying drawings, but the present invention is not limited thereto.
Examples
As shown in fig. 1, the present embodiment provides a multistage oil-water separation system including:
the multi-stage oil-water collecting pool at least comprises a first-stage oil-water separating tank 1 and a last-stage oil-water separating tank 5;
the oil collecting chamber 10 is arranged above each stage of oil-water separation tank, and the oil collecting chamber 10 is provided with a low-level outlet pipe 101 and a high-level outlet pipe 102;
a low level overflow pipe 11 communicated with the low level outlet pipe 101 through a low level gate valve 103;
the high-level overflow pipe 12 is communicated with the high-level outlet pipe 102 through a high-level gate valve 104;
the water phase collecting tank 6 is communicated with the final-stage oil-water separation tank 5 through a pipeline;
and the oil phase collecting tank 7 is respectively communicated with the low-position overflow pipe 11 and the high-position overflow pipe 12.
Further, the multistage oil-water collecting pool comprises a first-stage oil-water separating tank 1, a second-stage oil-water separating tank 2, a third-stage oil-water separating tank 3, a fourth-stage oil-water separating tank 4 and a final-stage oil-water separating tank 5 which are sequentially connected through a communicating water pipe 13. After the oil-water mixture is separated by the five-stage oil-water separation tank, the upper oil phase can be basically and completely recovered.
Further, still include recovery pipeline 8, recovery pipeline 8 connects oil phase collecting tank 7 and one-level oil water separating tank 1 respectively. The recovery line 8 is used to re-separate the oil phase from water, in which water remains.
Further, a feed inlet is formed in the top of the oil phase collecting tank 7 and is respectively communicated with the low-position overflow pipe 11 and the high-position overflow pipe 12; an oil phase discharge hole is formed above the side wall of the oil phase collecting tank 7; an oil-water discharge hole is formed in the bottom of the oil phase collecting tank 7 and communicated with the primary oil-water separation tank 1 through a recovery pipeline 8.
