GIVED ZTM EHTFEBBEX? VOF ON THE WATERB LAYERED POLLUTANTS

Addition to patent no. ₃ P 21 49 1-71 Λ

- The subject of the main patent is a process and a Device for removing layers of pollutants, especially oils, floating on a heavier liquid Water surface »

It is proposed there, with the help of a device pulled or pushed by a ship, built into a ship or firmly anchored in a river, to absorb water with the pollutants floating on it in a suitable layer thickness solely due to the relative movement and to increase this relative movement use ₉ the polluted water

to feed tangentially into one or more cyclone chambers ^ which causes a hotation ^ caused by a vortex zone . will the polluting liquid be concentrated in the center of it and removed from there by a drill _? which is guided axially through the "ceiling" of the cyclone chamber - the centrifuged water freed from the particulate matter is then transported outwards again from the tip of the cyclone »

The subject of this ". Addition is an execution variant,

The particularly compact device for the application of the method "concerns _f that can be attached to the side of a ship or pulled by it / in order to be moved on the surface of the water; it can also be converted into" a natural or artificial.

The attached figure gives a perspective view of this embodiment _{variant o}

This figure shows a first vertical planar wall portion 1 and a second vertical wall portion 2 ₅ having a curved wall 1 j, the approximate inner wall 10 and outer eiiie. flat wall 11 having laterally attached to the _{g "p} .ist- hull of a ship 9 which moves in the water to be purified F? · the pollutants and the water penetrate due to the movement in the taper. space along the arrow F.

This tapered space has two bands 3 and 4 _S on its underside as an additional guide for

the liquid flow along the arrow P ₁ in the direction of the tangential inlet 5 / in a cyclone chamber 6 should serve * · - -

The cyclone chamber 6 operates in the same way as described in the main patent; the purified water exits directly into the water along the arrow Fp through a tangential outlet 7 in the lower area of the chamber, while the pollutants are guided to the outside almost completely water-free along the arrow F ^ through a central opening 8 in the cover of the cyclone chamber ₀ This discharge of the pollutants can be achieved by suction by means of a pump, not shown; be reinforced.

The device described above is particularly interesting because it is suitable for different types of ships, for example small ones Tanker is suitable? it can, of course, in this form in a natural watercourse or an artificial current is used will. - -'.-- ". ■

Claims (1)

i / 23 "533 ¹ SB PATENT CLAIM Device for applying a process for removing pollutants floating on water surfaces, in which a suitably thick layer of water with contaminants floating on it solely under the effect of relative movement is recorded and this relative movement is used to tangential the water and pollutants into one or to introduce more cyclone separation chambers, according to the main patent no. P 21 49 171.4, characterized in that that it contains two vertical wall parts (1, 2), which form a narrowing water inlet, and the have inside edges (3, 4) on the underside, the inside (10) of one of these wall parts (2) being curved and the narrowing entrance the water and the polluting one Absorbs liquid and leads tangentially into a cyclone chamber (5), from which the contaminating liquid is almost completely freed from water through an opening (8) in the upper part is derived and collected in a container and from the the purified water in the lower area through a tangential Opening (7) is diverted into the surrounding water. 409820/0278
