Abstract

This invention relates to the protection of the waters of the oceans from pollution by oil and oil products. The purpose of the invention is to increase the efficiency of the device when collecting thin films of petroleum products by transferring them to a drip state. Oil is captured by the bow of the vessel 1, between the two flaps 2 of which there is a horizontal panel 3 made of a hydrophilic material and located on the surface of the water. The oil film trapped under the sheet 3 disintegrates into individual drops 6, which enter the vessel in the vessel 4 for the separation of the oil / water mixture. New in this device is the use of a hydrophilic surface for transferring a thin film of oil into a drip state, which allows collection of oil films with a thickness of less than 0.1 mm, using threshold-type oil collectors. 2 Il.

FIG. one

The invention relates to the protection of water. The ocean of the world against the i-th (z) and the oil of the genus.

The purpose of the invention is to increase the efficiency when collecting thin films of petroleum products by transferring them to a drip state.

FIG. 1 shows a device for collecting petroleum products, top view; in fig. 2 shows section A-A in FIG. one.

The device consists of an oil-collecting vessel, P1ika 1, which has an opening in the nose section, closed by two flaps 2. Between the flaps 2, a panel 3 of a hydrophilic material is installed horizontally on the water level. The cloth 3 is rigidly fixed on the wings 2. The front part of the cloth 3 along the vessel is raised above the water and forms an acute angle with the horizon. The hydrophilic panel 3 can be made from a metal mesh or from a material that is similar in properties to ceramics.

The opposite part of the hydrophilic web 3 is located above the tank 4 for collecting and separating the oil / water mixture. The flaps 2 of the vessel 1 are opened towards the oil spot 5.

The device works as follows.

When the device is moving, a film of oil is seized by the flaps of 2 vessels. The oil on the film falls under the hydrophilic panel 3, where the transfer of oil products to the drip state 6 takes place. Further, due to the movement of the vessel and friction against the hydrophilic panel 3, oil accumulates under it.

The oil film, when in contact with the ice-wetted sod, the surface of the cloth 3, in the presence of water, disintegrates in the section, 1 drops of different diameters. This is due to the fact that a thin film of water is formed between the oil and the surface.

In this case, the thickness of the drops is several times greater than the thickness of the initial n, 1 k.

whereby it becomes possible to efficiently collect them using existing oil gathering devices, for example, of a threshold type. The film of oil, falling under the rt-profile sheet 3, due to the action of viscosity and surface tension forces breaks up into separate drops 6, which are then collected by the vessel's oil recovery device and accumulated as an oil-water mixture in a container 4. collection and separation of water and oil.

The amount of oil entering storage tank 4 increases substantially in relation to the volume of water. This is due to the use of a hydrophilic surface that increases the thickness of the film. The device makes it possible to use threshold-type oil collectors in service for collecting thin films of oil products with a thickness of less than 0.1 mm, after having been equipped with a hydrophilic surface. /

The economic effect is to prevent damage to water bodies by contamination with thin oil films.
