Description
TITLE:
Continuous Flow Oil Water Separator FIELD
The present invention relates to an oil water separator which can accommodate a continuous flow.
BACKGROUND
Continuous flow oil water separators generally consist of a vessel having an inlet at a first end and an outlet at a second end. Some means is used to trap oil within the vessel as liquid flows from the first end to the second end. There is a need to improve the efficiency of the continuous flow oil water separators, to reduce the amount of oil that reaches the outlet.
SUMMARY
There is provided a continuous flow oil water separator which includes a vessel having a bottom and an upstanding wall that defines a liquid retaining interior. The vessel is positioned in a substantially horizontal orientation with an inlet at a first end and an outlet at a second end. At least one baffle is providing extending upwardly from the bottom to divide the interior of the vessel into compartments. An opening is provided through each baffle defining a spill-over weir between the compartments. A baffle guard provides a barrier to lateral flow through the opening in each baffle. Each baffle guard extending outwardly from the baffle and downwardly toward the bottom of the vessel to define a spill-over weir access channel having a channel inlet positioned toward the bottom of the vessel.
The continous flow oil water separator, as described above, effects separation based upon a difference in density of fluids; namely oil and water. The baffle guard tends to confine oil to an upper portion of the compartments, where it floats on water. It is primarily water drawn from the bottom of the vessel that passes from one compartment over the spill-over weir to the next comparnnent.
The longer the residence time, the greater the degree of separation. Even more beneficial results may, therefore, be obtained when there is more than one baffle. The more

The continous flow oil water separator, as described above, effects separation based upon a difference in density of fluids; namely oil and water. The baffle guard tends to confine oil to an upper portion of the compartments, where it floats on water. It is primarily water drawn from the bottom of the vessel that passes from one compartment over the spill-over weir to the next comparnnent.
The longer the residence time, the greater the degree of separation. Even more beneficial results may, therefore, be obtained when there is more than one baffle. The more
2 baffles that are provided and the more compartments that are created, the greater the residence time and the greater the degree of separation.
The residence time can further be enhanced by having the opening that defines the spill-over weir between successive baffles out of alignment, forcing liquid to follow a non-linear path from the inlet to the outlet.
Although liquids can be pumped through the vessel, it is preferred that the inlet at the first end be higher than the opening in each baffle defining the spill-over weir, and the opening in each baffle be higher than the outlet at the second end to promote a gravity induced flow from the inlet, over the spill-over weir to the outlet. Further to this, when there are a plurality of baffles, the opening that defines the spill-over weir in each successive baffle becomes progressively lower from the first end to the second end, to promote a gravity induced flow between compartments.
There is a further advantage in having oil separated, to the extent possible as it flows into the vessel. By having a tray with a retention lip underlying the inlet, liquid entering the vessel has to pass onto the tray and then spill over the retention lip. By slowing the entry of the liquid into the vessel, the majority of the oil that enters the vessel will end up floating on the surface of water in the very first compartment and will never pass to subsequent compartments. This can be enhanced by having an oil diversion outlet to skim oil floating on a surface of liquid in the tray, so it never spills into the first compartment.
It is preferred that plugs be positioned in each compartment either in the bottom or in the wall adjacent to the bottom to facilitate flushing of each compartment during maintenance.
It is also preferred that the vessel have a removable lid to provide access during maintenance.
The lid prevents persons or debris from falling into the vessel. During maintenance, the lid can be opened to allow skimming of oil floating on the surface of water. Any granular matter which settles can also be scooped out inbetween flushing or instead of flushing.

DETAILED DESCRIPTION
A continous flow oil water separator generally identified by reference numeral 10, will now be described with reference to FIG. 1 and 2.
Structure and Relationship of Parts:
Referring to FIG. 1, continuous flow oil water separator 10 is in the form of a vessel 12 having a bottom 14 and an upstanding wall 16 that defines a liquid retaining interior, generally indicated by reference numeral 18. Vessel 12 is maintained in a substantially horizontal orientation with an inlet 20 at a first end 22 and an outlet 24 at a second end 26. It is preferred that inlet 20 at first end 22 be higher than outlet 24 at second end 26 to promote a gravity induced flow through vessel 12 from inlet 20 to outlet 24. A tray 28 with a retention lip 30 underlies an inlet pipe 32 which extends into interior 18 through inlet 20. Liquid entering vessel 12 passes onto tray 28 and then spills over retention lip 30 into interior 18.
Referring to FIG. 2, an oil diversion outlet 33 is provided to skim oil floating on a surface of liquid in tray 28 from vessel 12. Although vessel 12 could work to some degree with a single baffle, it is preferred that there be more than one baffle. In the illustrated embodiment, three baffles 34, 36, and 38 have been illustrated. Referring to FIG. 1, each baffle 34, 36, and 38 extend upwardly from bottom 14 to divide interior 18 of vessel 12 into four compartments 40, 42, 44, and 46. There is an opening 48, 50 and 52 respectively through each of baffles 34, 36, and 38 respectively defining spill-over weirs 54, 56, 58, respectively. To pass from compartment 40 to compartment 42, liquids must pass over spill-over weir 54.
To pass from compartment 42 to compartment 44, liquid must pass over spill-over weir 56. To pass from compartment 44 to compartment 46, liquids must pass over spill-over weir 58.
Openings 48, 50 and 52 through baffles 34, 36, and 38 respectively that define spill-over weirs 54, 56, and
4 58 respectively in each successive baffle becomes progressively lower from first end 22 to second end 26. The last spill-over weir 58 is higher than oulet 24 to promote a gravity induced flow between compartments 40, 42, 44 and 46. Referring to FIG. 2, each opening 48, 50, and 52 that defines spill-over weir 54, 56, and 58, respectively between successive baffles 34, 36, and 38 respectively is out of alignment, forcing liquid to follow a non-linear path from inlet 20 to outlet 24. Referring to FIG. 1, baffle guards 60, 62 and 64, respectively providing a barrier to lateral flow through opening 48, 50, 52 respectively of baffles 34, 36, and 38 respectively. Each baffle guard 60, 62, 64 extends outwardly from their respective baffles 34, 36, and 38 and downwardly toward bottom 14 of vessel 12 to define a spill-over weir access channel 66 having a channel inlet 68 positioned toward bottom 14 of vessel 12. Outlet 24 is also protected by a baffle guard 70. Baffle guard 70 also defines an access channel 66 having a channel inlet 68 positioned toward bottom 14 of vessel 12.
Removable plugs 72 are positioned in each compartment 40, 42, 44, and 46 either in bottom 14 or in wall 16 adjacent to bottom 14 to facilitate flushing of each compartment during maintenance. In the illustrated embodiment, removable plugs 72 are in bottom 14. It is preferred that vessel 12 have a removable lid for maintenance access.
Operation:
In operation, it is preferred, but by no means essential, that vessel 12 be filled with water to start. Referring to FIG. 2, water containing oil it then directed through inlet 20, along inlet pipe 32 and then fills tray 28. As the liquid level rises in tray 28, a portion of the liquid floating as a layer on top is allowed to exits vessel 12 though outlet 33. It is presumed that this will primarily be oil and, for that reason outlet 33 is referred to as an "oil diversion outlet". When tray 28 is completely full, the contents of tray 28 both water and oil spill over retention lip 30 into compartment 40. As compartment 40 is already filled with water, most of the oil floats on the water within compartment 40. Referring to FIG 1, as the inflow of liquids continues into vessel 12, liquid passes through through opening 48 in baffle 34 and flows over spill-over weir 54 into comparhnent 42. In order to pass through opening 48 the liquid must enter channel inlet 68 and pass up spill-over weir access channe166. As channel inlet 68 is positioned toward bottom 14 of vessel 12, it is presumed that relatively little oil will reach opening 48. As compartment 42 fills with liquid, liquid will pass through opening 50 in baffle 36 and flow over spill-over weir 56 into compartment 44. In order to pass through opening 50 the liquid must enter channel inlet 68 and pass up spill-over weir access channel 66. As channel inlet 68 is positioned toward bottom 14 of vessel 12, it is again presumed that relatively little oil will reach opening 50. As compartment 44 fills with liquid, liquid will pass through opening 52 in baffle 38 and flow over spill-over weir 58 into comparlment 46. In
Removable plugs 72 are positioned in each compartment 40, 42, 44, and 46 either in bottom 14 or in wall 16 adjacent to bottom 14 to facilitate flushing of each compartment during maintenance. In the illustrated embodiment, removable plugs 72 are in bottom 14. It is preferred that vessel 12 have a removable lid for maintenance access.
Operation:
In operation, it is preferred, but by no means essential, that vessel 12 be filled with water to start. Referring to FIG. 2, water containing oil it then directed through inlet 20, along inlet pipe 32 and then fills tray 28. As the liquid level rises in tray 28, a portion of the liquid floating as a layer on top is allowed to exits vessel 12 though outlet 33. It is presumed that this will primarily be oil and, for that reason outlet 33 is referred to as an "oil diversion outlet". When tray 28 is completely full, the contents of tray 28 both water and oil spill over retention lip 30 into compartment 40. As compartment 40 is already filled with water, most of the oil floats on the water within compartment 40. Referring to FIG 1, as the inflow of liquids continues into vessel 12, liquid passes through through opening 48 in baffle 34 and flows over spill-over weir 54 into comparhnent 42. In order to pass through opening 48 the liquid must enter channel inlet 68 and pass up spill-over weir access channe166. As channel inlet 68 is positioned toward bottom 14 of vessel 12, it is presumed that relatively little oil will reach opening 48. As compartment 42 fills with liquid, liquid will pass through opening 50 in baffle 36 and flow over spill-over weir 56 into compartment 44. In order to pass through opening 50 the liquid must enter channel inlet 68 and pass up spill-over weir access channel 66. As channel inlet 68 is positioned toward bottom 14 of vessel 12, it is again presumed that relatively little oil will reach opening 50. As compartment 44 fills with liquid, liquid will pass through opening 52 in baffle 38 and flow over spill-over weir 58 into comparlment 46. In
5 order to pass through opening 52 the liquid must enter channel inlet 68 and pass up spill-over weir access channel 66. As channel inlet 68 is positioned toward bottom 14 of vessel 12, it is again presumed that relatively little oil will reach opening 52.
As comparhnent 46 fills with liquid, liquid will pass out of vessel 18 through outlet 24. In order to pass through outlet 24, the liquid must enter channel inlet 68 and pass up access channel 66. As channel inlet 68 is positioned toward bottom 14 of vessel 12, it is again presumed that relatively little oil will reach outlet 24. It can be seen from this description that as water moves from compartment to compartment less and less oil is likely to be carried with it. The number of compartments can be increased or decreased to meet the needs of a particular application. If required, chemicals can be added to promote separation of the oil and the water. It is preferred to avoid the use of chemicals, if at all possible, so as to reduce any environmental impact associated with the disposal of water exiting outlet 24.
Maintenance of continous flow oil water separator 10 is relatively simple. Liquids diverted through oil diversion outlet 33 will accummulate in a container and must be periodically disposed of. Oil that floats on the water in each of compartments 40, 42, 44, and 46 should be periodically skimmed. It is preferred that grit be removed by filters prior to the liquids entering vessel 12.
Where that is not practical, vessel 12 should be periodically drained, plugs 72 removed and grit flushed from vessel 12. In some applications it may be desirable to pump liquids through vessel. This is not necessary for most applications,l as inlet 20, openings 48, 50, and 52 in baffles 34, 36, and 38, respectively, along with outlet 24 have been configured to promote gravity flow through vessel 12 in response to a continuous inflow of water contaminated with oil.
In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
As comparhnent 46 fills with liquid, liquid will pass out of vessel 18 through outlet 24. In order to pass through outlet 24, the liquid must enter channel inlet 68 and pass up access channel 66. As channel inlet 68 is positioned toward bottom 14 of vessel 12, it is again presumed that relatively little oil will reach outlet 24. It can be seen from this description that as water moves from compartment to compartment less and less oil is likely to be carried with it.
