Title: Device for recovering oily polluting liquid from a water surface
IPC: E02B15/10
Filed: 1973-09-12
Abstract: 1439670 Floating filter INSTITUT FRANCAIS DU PETROLE 12 Sept 1973 [18 Sept 1972] 42885/73 Heading B1D A floating filter device for removing oily polluting material from a water surface comprises a water floatable container having a first container portion which has a wall at least a portion of which is porous, hydrophobic and oleophilic, so as to selectively pass oily material and resist passage of water, a second container portion having an impervious wall and in communication with the first container portion to allow flow of oily material therebetween and a vent to allow escape of air from the container. In one embodiment (Fig. 3) a cylindrical container is ballasted by a weight 6 to float with its axis vertical and is formed such that the resultant lower part of the container 3 forms the first container portion having a porous wall through which oil will pass into the container and the upper part of the container 2 is the second container portion bounded by the impervious wall. When the first container portion has filled with oil, the container is turned upside down for removal from the water surface, with resulting flow of oil into the impervious-walled second container portion. The container may be turned manually or automatically, as shown in Fig. 3, by means of a connecting element 4 which dissolves in oil and releases the ballast weight, connection 18 the weight falls away and by virtue of hitherto loose connection 20 to the top of the container, it inverts the container. The vent 11 has an extended outlet pipe 10 connected thereto to prevent escape of oil on inversion. Annular shock absorbers 12 are mounted around the outside of the container. In a further embodiment (Fig. 4) the whole outside wall 15 of the container is formed of the oil porous material and the impervious wall is mounted coaxially within and spaced from the outer wall 15 to define an outer annular first container portion and an inner cylindrical second container portion 9, the two portions communicating by means of apertures 17 at the lower end (in use) of the container. The container is again inverted for collection and oil collects in the inner container portion. The vent has a valve to prevent escape of oil on inversion. A third embodiment is described (Fig. 5 not shown) similar to construction to the Fig. 4 embodiment, but to which the container is not inverted for collection but rather the connecting passages between the first and second container portions are closed by a valve member attached to a lifting handle on top of the container. The porous wall may be heated to reduce the viscosity of oily material passing therethrough.
