Abstract

The invention relates to environmental protection. The purpose of the invention is to expand the functionality of the device by using it to collect oil from the surface of the water during a wave. The device consists of a vertical pipe immersed in liquid 1 with a float 2 enclosing it. An inlet valve 3 is located in the upper end wall of pipe 1. At the top of pipe 1, a branch pipe 10 with valve 11 is installed on its cylindrical surface to pump bulk oil. The float 2 is mounted so that it can move along the axis of the pipe 1. The device is installed vertically in the pond, ensuring that the float 2 moves the upper end of the pipe 1 with the level of the liquid in the pond. During agitations, the fluid level inside pipe 1 decreases, valve 3 opens, and the upper layers of the liquid contaminated with oil merge into pipe 1, from where it is periodically pumped out through valve 10c with valve 11.

Description

The invention relates to environmental protection, in particular to the cleaning of surfaces of water bodies from oil and oil products.

The purpose of the invention is to expand the functionality of the device by using it to collect oil from the surface of the water during agitation.

FIG. 1 shows the device, a general view; figure 2 - the location of the valve, plow shop and the upper cut of the pipeline relative to the surface of the water; Fig. 3 valve in the closed position; Fig.4 valve in the open position; Fig. 5 shows a kinematic diagram of the operation of the device.

A device for vertically moving a liquid inside a pipeline located in a reservoir includes a vertical pipe 1, a float 2 for holding pipe 1 in a reservoir in a vertical position and installing an upper end of the pipe on the surface of the reservoir, inlet valve 3 mounted on the end wall of pipeline 1.

Float 2 (Fig. 1.2) is placed on pipeline-1, covering it, and installed below the level of the reservoir. The exhaust valve 3 (fig; 3,4) is equipped with limiting pins 4, a rubber sealing ring 5, guide pins 6, passed with a gap through the holes 7 of the stopper 6, having a channel 9 for the passage of the collected liquid. The pipeline 1 is also equipped with a drain pipe 10 with a valve 11.

The device works as follows. The device is installed vertically in a pond where it is necessary to provide a selection of oil and petroleum products from the surface of the reservoir into pipe 1. In the absence of waves, the WATER level inside pipe 1 corresponds to the level of the calm sea surface, and the upper end of pipe 1 is through float 2 which is made moving through conduit 1 to provide operation of the device in media with different densities, is installed on the surface of a reservoir under a film of oil. The upper cut of the pipeline 1 by means of the float 2 tracks the surface waves, as a result of which the device makes oscillatory movements in the vertical direction.

Under agitation, when the upper end of the pipeline 1 is on the crest of the surface wave and the fluid in the pipeline moves down, the inlet valve 3 opens and under its own weight drops down, supported by pins 4 into the stop valve

washer 8, thereby providing a liquid runoff with a film of oil from the surface of the reservoir through the gap between valve 3 and lock washer 8 and channel 9 into the interior of pipeline 1. At that moment, when the upper end of pipeline 1 is between the tops of the waves (in the hollow), the liquid in pipe 1 moves upward and presses valve 3 against rubber seal 5,

the return of fluid from the pipeline to the outside is prevented. In the case described, a disc valve is used. Other intake valve designs are also possible, providing

low hydrodynamic resistance to the flow of fluid that moves upwards and closes the valve.

The process of liquid flow with a film of oil and oil products inside the pipeline

lasts all the time while the upper cut of conduit 1 is within the wave apex. Extraction of the oil accumulated in pipeline 1 is produced through a drain connection with a valve, for example

type saddle-ball, by known methods (not shown), for example, by connecting to a drain pipe 10 with a valve 11 pump with a tank located on the vessel (in case of installation of the device in an open pond near marine sanitary platforms), or by draining oil from pipeline 1 into the well-trap and pumping it out of the last gas-lift method (if the device is installed in a network of branched stations, where the approach of ships with a pump and tank is impossible). A drainage nozzle with a valve is located in the upper part of the pipeline for the convenience of connecting it to a pump with a tank or to

well trapped. The oil is drained into the well trap when the valve is opened at the drain connection automatically through the water flow from the reservoir to the pipeline.
