Definitions
- the invention relates to a method and associated apparatus for separating liquid, oil such as in particular petroleum or its liquid chemical products containing mixtures in their at least one aqueous and non-aqueous phase.
- the non-aqueous fractions present in the mixture should be as completely as possible separated from the aqueous fractions and then removed from the liquid mixture.
- Petroleum or oil-containing substances reach in many ways in waters. For example, even with normal oil production on oil platforms, larger quantities of oil return to the seawater due to the existing production water. Further oil pollution occurs due to the oil tankers used to transport the oil. Not only the oceans, but also the inland waters are polluted by industrial plants and by inland navigation with oil. In addition to this normal pollution, not inconsiderable quantities of oil continue to be released through incidents in both inland waters and in the oceans.
- oil barriers are known in connection with oil control measures on the water surface in order to prevent the spread of an oil slick floating on the water. Also, such oil spills are sucked by special tankers, but only partially succeed.
- the present invention seeks to provide a method and a corresponding device for separating an oil contaminated with oil, in particular petroleum or oil-containing substances aqueous mixture, which allows the separate aqueous phase to initiate directly into inland waters to be able to.
- An agitator within the centrifuge can be additionally provided.
- the exiting liquid can again - also several times - be passed through the existing centrifuge.
- FIG. 1 shows a schematic representation of a cleaning device according to the invention, with which the method according to the invention can be carried out
- FIG. 2 shows a detail of the device according to the invention according to Fig. 1
- Fig. 3 is a perspective view of that used in the invention
- Binder dosing agent for introducing the binder into the contaminated with residual oils oil-water mixture.
- aqueous mixture is sucked by means of a driven by a motor 12 pump 14 in a designed as a suction line 16 dirt line and in a pressure line 18 tangentially above (inlet 21) introduced into a centrifuge 20.
- the rotational movement 22 of the liquid present in the centrifuge 20 taking place in the centrifuge 20 is generated in the present example case solely by the pressure generated by the pump 14.
- oil binder 100 held in stock in a storage container 100 is added by means of a metering device 26 to the suction line 16.
- the solid binder 100 could agglomerate upon compression, so that it, as described in more detail below, sucked into the dirt line and is not pressed.
- the binder could alternatively or additionally be added directly to the centrifuge 20.
- the binder 100 mixes for the most part with the oil present in the aqueous mixture which forms as a non-aqueous phase (oil layer 29) on the inner surface region 27 of the liquid cone forming in the centrifuge 20.
- the inner wall surface 28 of the centrifuge 20 is circular-cone-shaped, tapering downwards.
- the resulting in connecting the binder 100 with oil flakes 30 are led out together with the remaining present in the centrifuge liquid 32 from a central bottom outlet 34 from the centrifuge and passed through a line 36 into a rotary pool 38.
- This outflow through the line 36 takes place solely due to the existing hydrostatic gradient.
- the liquid level forming in the centrifuge 20 is higher than the water level 40 present in the rotary basin 38.
- the liquid 32 introduced into the rotary basin 38, together with the flakes 30 present in it, is set into slight rotational movement 46 by means of an agitator 44 arranged in the region of the bottom 42 of the rotary basin 38 brought.
- This rotational movement 46 is much smaller than the rotational movement 22 in the centrifuge 20 in the present example case.
- the agitator 44 is driven by a motor 48 foreign.
- the flakes 30 unite to form balls 50.
- the small binder constituents which are otherwise present in the liquid 32 and to which oil or similar substances also adhere are sometimes also deposited on these balls 50.
- These balls 50 float on the water surface 40 and are cyclically removed from the rotary tank 38. The latter takes place in the present example case by skimming the balls 50.
- a bottom outlet 52 from which the present in the rotary tank 38 liquid 32 is introduced via a line 54 into a tank 56.
- the purified aqueous phase introduced into the tank 56 may still contain a small amount of suspended matter. These suspended solids are small flakes of bound oil or similar substances. In addition, residues of unused binder may still be present, which is the case for example with an overdose.
- the suspended on the surface of suspended matter are led out of the top of the tank 56 and introduced in the present example case by means of a return line 58 tangentially (inlet 59) in the centrifuge 20 again.
- the aqueous phase can be reused in a line 66 as service water or introduced directly into inland waters.
- At least one centrifuge 20 and at least one rotary tank 38 are used - in addition, the liquid mixture exiting in the different stages again - even multiple times - by the existing centrifuge (s) 20th be directed.
- shut-off valves 68, 70 are present in the respective lines.
- Lines 58, 66 may also be corresponding, not shown in the drawing shut-off devices. The same applies to the leading to the centrifuge 20 suction or pressure line 16, 18th
- the binder-dosing device 26 has two branch channels 74, 76 which open vertically into the suction line. These two branch channels are present in a carriage 78, which can be moved back and forth in the longitudinal direction 81 parallel to the suction line 16 by means of a motor 80. In one end position, there is a branch channel 74 in front of a wall opening 82 of the suction line 16 and the other branch channel 76 in front of the outside of this suction line 16. This position is shown in FIG. In the other end position of the carriage 78, the first-mentioned branch channel 74 is in the position of the branch channel 76, d shown in FIG. H.
- one of the two branch channels 74, 76 is always located in front of a wall opening, either in front of the wall opening 82 or in front of the wall opening 84.
- a piston 86 or 88 can be moved back and forth in the transverse direction 94 by means of a respective motor 90, 92.
- the piston 86 In the position shown in Fig. 3, the piston 86 is located in the branch channel 74 in the maximum extended position, so that it closes the wall opening 82.
- the other piston 88 in the other branch channel 76 is in its maximum retracted position. In this retracted position, binder 100 can flow from above into a reservoir tank 76 open from above, from a reservoir 24 placed above this branch channel 76.
- this binder 100 containing stitch channel 76 passes in front of the wall opening 84.
- the flowing through the suction pipe 16 oil-water mixture ruptures the present in the branch channel 76 binder 100 and thus the stitch channel 76 out.
- the piston 88 is moved by motor in the branch channel 76 continuously in the direction of the suction line 16.
- the metering device 26 can also be used in the region of the pressure line 18.
