Description

The invention relates to the cleaning of a water surface from light floating liquids, and more particularly, to a technique for collecting oil products from a surface of flowing water. The invention can be used to clean the water surface of rivers and streams from oil products in areas of oil production and refining, as well as when using oil products.

The purpose of the invention is to simplify the design and increase the efficiency of the device.

In FIG. 1 shows a device in longitudinal section; in FIG. 2 - view A of the capturing and directing boom.

The proposed device contains a settling tank 1 in the form of a tray turned upside down with floats 2, providing buoyancy with the bottom at a water level, a fitting 3 with a valve for draining the trapped oil from the cavity of the tank 1 and

directing the flow of water upward pipe 4 inside. The pipe 4 using a flexible pipe 5 is connected to the ejector 6, buried in the water. The working nozzle 7 of the ejector 6 is connected to the confuser 8, immersed in water and in communication with it, and the receiving chamber 9 of the ejector 6 is connected to the oil receiving funnel 10, to which is attached a U-shaped planar gripping guide 11, in the form of a barrier shaped plate, open against the flow of water. The oil receiving funnel 11 is located directly below the water level. An ejector 6 is attached to the container body 1 by means of a linkage system 12, which allows the container 1 to move in a vertical plane. The ejector 6 is equipped with a float 13.

The device operates as follows.

The device is placed in water, where there is the greatest flow, and fixed in the position when the confuser 8 and boom 11 are directed against the flow of water. The device can be fixed with the help of korah, screw anchors or in another way.

The flowing water enters the confuser 8, where the velocity head of water is summed up, as a result of which a stream of water comes out of the working nozzle 7, having a speed greater than the speed of the water in the river. Under the influence of a water jet in the receiving chamber 9 of the ejector 6, the effect of sucking in water from the oil receiving funnel 10 is created, where surface water enters, which contains floating film or drip oil. The U-shaped boom 11 captures surface water from a larger area and directs it to the inlet of the oil receiving funnel 10. Thus, the water entering the confuser 8. creates the effect of sucking water, and the tank 11 captures water from a larger surface, concentrating it over the oil receiving funnel 10. Water from the confuser 8 in a mixture with surface water enters through a pipe 5 to a pipe 4, which directs water with oil to the upper part of the cavity of the tank 1. Light fraction - when settling, oil is separated from the water and floats up. Over time, the trapped oil accumulates in the cavity of the tank 1, after which the collecting vessel approaches the device, sucks the trapped oil through the nozzle 3 and takes it to the onshore oil storage facilities for further disposal.

Water freed from oil in the cavity of the container 1 flows down and enters the flowing water.

In the absence of oil in the cavity of the tank 1, it is afloat, and its bottom is at the level of the water surface in the river. When oil accumulates in the tank, the bottom of the tank 1 begins to rise above the surface of the water due to a column of oil in

capacities, since oil (oil product) has a lower density than water. When lifting the bottom of the tank to a certain (calculated) height, oil is pumped from tank 1. Due to the fact that the ejector 6 is equipped with a float 13, it is always afloat at a given depth regardless of the position of the container 1.

Using the invention will allow

significantly simplify the design of the device without reducing the efficiency of oil capture from the surface of the flowing water, since in the cavity of the tank the speed of water with oil decreases sharply, which increases the settling effect. The settling tank is very simple in the device, it is a tray turned upside down, resulting in a decrease device cost.
