An instantaneous separation system for capturing and recovering oil from an outdoor electrical equipment. The system includes a capture system for capturing a mixture of oil and water and transporting the mixture to an instantaneous separation reservoir. The separation reservoir maintains the separated oil and water separate via a separation plate. A water outlet pipe transports the separated water back to the surroundings, an oil outlet pipe transports the separated oil to an oil reservoir; a nominal water level threshold maintains the separated water at a given water height by directing any water surpassing the water height to the surroundings via the water outlet pipe. The nominal water level threshold and the separation plate ensure that substantially only the separated water enters the water outlet pipe. An oil outlet threshold is positioned at a height that is greater than the height of the nominal water level threshold.

A separation apparatus includes: a partitioning member inside a separation tank, includes erect and transverse portions, and partitions the tank into inflow and outflow regions of a liquid; an inlet of which a lower level is set to be lower than an upper end of the erect portion and an upper level is set to be higher; a screen in the erect portion along a flow direction of the liquid; a swirling inducing member in the erect portion intersecting with the flow direction of the liquid; a screen in the transverse portion; a dividing member dividing the liquid flowing in from the inlet into flows along side walls of the separation tank; a retaining member at a downstream side in the flow direction and retains the substance having the specific gravity less than that of the liquid; and an outlet through which the liquid flows out from the outflow region.

The present invention relates to a group and method for the separation of a mixture comprising two fluid phases mutually at least partially immiscible and with different specific density characterized in that it comprises a closed chamber (11) which extends between an upper outlet mouth (12a) of a fluid phase with lower specific density separated from the mixture, positioned at a first upper height, and a lower outlet mouth (12b) of a fluid phase with greater specific density separated from the mixture, positioned at a second lower height with respect to the first upper height, an inlet (15,33) for said mixture inside said closed chamber (11) also being present at a height interposed between said upper and lower heights, a first upper gross separation device (13) of said mixture and a second lower fine separation device (14,14′) of said mixture, hydraulically connected to each other (13) (14), being situated in succession, inside said closed chamber (11), between said upper outlet mouth (12a) and said lower outlet mouth (12b), the first upper gross separation device (13) comprising a gravitational separation chamber and the at least second lower fine separation device (14,14′) comprising at least one coalescence separator (14) and/or at least one hydrocyclone separator (14′).

A water-oil separation device uses a difference in density between water and oil. The water-oil separation device can easily and quickly separate oil by using a polymer film floating at interface between water and oil. The water-oil separation device easily and quickly collects oil of various viscosities with a simple structure by using differences in density between materials without using a conventional lyophilic/lyophobic film, thus solving the drawbacks of conventional filter-based and adsorption-based methods, and enabling quick and effective responses to actual oil spill situations.

An organic waste collection apparatus includes a box, a conveying device, a separation device, a squeezing device, a heat shrink device and a recycling device arranged at an upper part of the box for separating a waste bag; a crushing device and a residue treatment device arranged at a lower part of the box for crushing and collecting organic waste; a central control device and a negative pressure purification device arranged in the middle of the box. In the resent disclosure, the waste bags are separated and collected separately, the waste is crushed and stored and transported in the form of residue, or the residue is further performed dry-wet separation, oil-water separation to collect oil, which can realize the safe and efficient treatment of organic waste.

A container for receiving and holding effluent water containing oil/grease to be removed including a sealed enclosure. In one example, a cover supports a partially immersed rotatable disk; a drive on the main sectional cover rotates the disk; a trough on the main sectional cover straddles the disk; and a blade on the trough scrapes a side of the disk, to direct oil and grease from the disk along the scraper blade along the trough for collection in a storage container. Efficiencies of construction of the sectional covers, disk and a sensor probe are disclosed in some examples. Also disclosed are apparatus, system and methods for a sealed container for receiving and holding effluent water containing oil/grease to be removed.

A cyclonic inlet diverter for initiating the separation of a multi-phase inlet fluid flow comprises an enclosed tubular body mounted crosswise within a larger separator vessel. The inlet diverter includes a splitter plate positioned within a center portion of the tubular body and configured to split the inlet flow into a first stream and a second stream, and a swirl plate positioned on each side of the splitter plate with angled surfaces configured to increase the cyclonic motion of the first and second streams within the tubular body. The inlet diverter further includes elongate apertures formed through bottom sidewall portions of the tubular body on each side of the splitter plate, an axial aperture formed through opposing end caps of the tubular body, and at least one radial aperture formed through lateral sidewall portions of the tubular body proximate each opposing end cap.

A fluid separation system for separating fluids within a container includes an inlet pipe arranged within the container to receive an incoming fluid stream including first, second, and third fluids. The fluid separation system further includes a fluid distribution device coupled to the inlet pipe and including first and second distribution components for respectively separating the incoming fluid stream into first internal fluid streams and second internal fluid streams within the container. The first and second internal fluid streams each include the first, second, and third fluids. The fluid separation system further includes one or more walls arranged to guide the first and second internal fluid streams towards an outlet of the container. The fluid distribution device and the one or more walls together cause the first, second, and third fluids of the first and second internal fluid streams to separate from one another other upstream of the outlet.

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.

A method of separating the components of a multi-phase fluid includes directing a flow of the multi-phase fluid into the lower inlet end of an inclined elongate separator vessel and then gradually forward and upward toward a weir plate proximate an upper outlet end, thereby allowing the multi-phase fluid to separate into a gas/vapor component and a liquids component, with the gas/vapor component flowing upward and forward along an inclined top inner surface and the liquids component further separating under gravity into a lower mixed oily water portion and an upper stratified portion defined by a clear water component, a partially oily water component, and a skim oil component. The method includes causing the skim oil component to flow over an upper edge of the weir plate that defines the liquid level in the separator vessel and into a skim oil section, and then withdrawing each the gas/vapor, skim oil, and clear water components from the separator vessel through separate outlets.
