Description

Oil-polluted water combined type settlement separator

The utility model is the treatment facility of oil-polluted water.

Though the effluent quality of existing cross-current coalescence degreaser has reached predetermined index, but also there are some shortcomings, the one, its gravity type rectangular bar of steel structure can't be made tun, and maximum gauge can only be accomplished 4m after making the pressure type cylinder tank into, because the load of cross-current coalescence degreaser is by the sectional area decision of cylinder, and area of section is immutable, so will change surface loading, in parallel jar number can only be increased, equipment investment must be increased like this.As the length that prolongs jar, can only increase the time of staying of sewage in jar, load still can fall; The 2nd, the top of cross-current coalescence degreaser filler must be provided with oil-collecting oil extraction space, the bottom must be provided with collection mud spoil disposal space, and the filler in the device is big to the resistance of current, makes oil-collecting, collection mud space that channelling and short circuit very easily take place, cause the effluent quality instability, effluent quality is poor.

The purpose of this utility model is a kind of oil-polluted water combined type settlement separator of design, and it can solve the cross section immutable problem of loading, and can reduce load effectively, reduces the time of staying of sewage in jar; It can eliminate oil-collecting, channelling and short circuit problem take place in collection mud space, makes stable effluent quality, water quality meet standard.

The utility model comprises left end socket 1, right end socket 2, cylindrical shell 3, median septum 12, left clapboard 5, right clapboard 6, down to stream type sloping plate component 8, upward flow type sloping plate component 11, cylindrical shell 3 left and right end portions become complete horizontal cylinder pressure vessel by left end socket 1 and 2 sealings of right end socket, left clapboard 5, median septum 12, right clapboard 6 is divided into left cushion space 14 with internal tank, down to fluid space 15, upward flow space 16 right cushion spaces 17, left side cushion space 14 communicates to the top of fluid space 15 at left clapboard 5 with following, communicate with the bottom of upward flow space 16 to fluid space 15 down at median septum 12, upward flow space 16 communicates on the top of right clapboard 6 with right cushion space 17, is being separately installed with down to stream type sloping plate component 8 and upward flow type sloping plate component 11 to the middle part of fluid space 15 with upward flow space 16 down.The water of this mechanism is entered from left cushion space 14 by water inlet pipe 18, flow to from left clapboard 5 tops down again to fluid space 15, flow through down to stream type sloping plate component 8, adopt big following in gap to be beneficial to oil slick come-up and silt particle sedimentation here, avoid producing and stop up to stream type sloping plate component 8; Water flows to upward flow space 16 from the bottom of median septum 12, the upward flow type sloping plate component 11 of flowing through, adopt the little upward flow type sloping plate component 11 in gap here, it can make tiny silt particle do not taken away by water, also can further remove oil slick, water flows to right cushion space 17 from the top of right clapboard 6 again, is flowed out by outlet pipe 19 at last.

The utility model has overcome the cross section immutable shortcoming of loading, and has effectively reduced load, has reduced the time of staying of sewage in separator; It has eliminated oil-collecting, channelling and short circuit phenomenon take place in collection mud space, makes stable effluent quality, and water quality meets standard.It is suitable for the processing of low concentration ternary sewage.
