DE8032677U1 - DYNAMIC OIL WEIGHER FOR LIQUIDS - Google Patents

Description

The innovation relates to a dynamically acting oil defense device for use on liquids, in particular Bodies of water.

Conventional oil skimmers usually work according to the adhesion or suction process. Before Devices, the oil is dammed up by the flow. The prerequisite for the effectiveness of the devices is that a sufficiently thick layer of oil forms directly on the intake system.

However, the formation of eddies in front of the recording device creates a backflow which prevents any significant oil layers reach the oil skimming systems directly. The effectiveness of these devices is also negatively influenced by the sea and current conditions.

The object of the present invention is to create an oil weir with the help of which large oil film thicknesses are dammed up can be so that an effective separation of the oil is possible.

According to the invention, the solution to this problem consists of one or more consecutive, approximately vertical ones Walls which are arranged approximately transversely to the direction of flow and whose upper edges are below the On the surface of the liquid. These walls are placed some distance in front of the actual retaining wall.

The invention is illustrated by way of example in

The dynamic oil weir for liquids is shown in the direction of the arrow flowed towards. The flow can be caused by a natural movement of the device (ship) or by natural Fluid movement (e.g. flowing water, ocean current) can be caused. Have model tests shown that 1 vortex form behind the walls, over the walls 1 flows oil and water. The water flows, since it is specifically more difficult, downward through the perforated bottom part 4. Behind each transverse wall 1, the is overflowed by the two liquids, the speed of the liquid particles decreases. It will be like this behind each wall 1 an increase in the oil layer 9 is achieved, which is well removed from the retaining wall using the known method can be. Among other things, the oil layer 9 can flow over can be skimmed off via a weir located just below the surface of the oil.

The side plates 2 are used to hold the walls 1 and prevent the pent-up from escaping from the side Oil 9. With the help of the floating body 3, the articulated abutment 5 and the adjustment device 8 the oil weir can be moved in a vertical direction. It can be the immersion depth, the flow velocity, the amount of oil and adapted to the surface contour. The sealing plates 7 overlapping with the side plates 2 ensure a mobility of the oil weir in relation to the retaining wall 6.

The dynamic oil weir is suitable for specifically lighter ones to separate from specifically heavier, liquid substances and to accumulate in front of a retaining wall.

A specially constructed oil rescue ship can use this Device can be equipped, with an arrangement in the direction of flow in front of the hull or in the hull possible is. By means of the height adjustment device 8 for the joints 5, the oil weir can be used while driving

stowed away on deck.

Another possible use is as an oil weir for rivers, whereby the device can be attached to existing floating pontoons or permanent hydraulic structures can be added.
