Description

The utility model relates to devices for collecting oil and oil products and other liquid water-immiscible substances floating on it, and can be used in the oil, petrochemical industries, various industrial plant oil traps, and in order to protect water bodies from pollution by these substances, and It is for the collection and separation of liquids with different specific gravities spreading over the surface of a reservoir.

Known devices for capturing floating pollutants from the surface of the water, containing various bodies, receiving funnels for receiving oil and oil products spreading from the surface of the reservoir, containing various mechanisms for the directed movement of oil and oil products from water surfaces into receiving funnels and taking oil and oil products from them, and feeding them to various containers, sedimentation tanks, and various other stationary treatment gravity separators and devices.

A known method of collecting floating liquids from a mirror of water, for example oil, by drawing in floating bodies of an artificially created vortex funnel and sucking out a mixture of floating liquid and water from it with a pump containing a lot of devices: a housing, a receiving vortex funnel that draws oil located on the surface of the water into a funnel with a screw that is driven by an electric motor through a gearbox and a process automation device to increase the high collection efficiency (RF patent No. 268277).

This method contains a lot of devices, apparatus-intensive, complicated in the housing design, requires up to four electric motors with gears, up to four screw suction systems in the receiving funnels, up to four pumps for pumping oil into the receiving tank, on which the collected oil is transported, up to four rather complex systems automation of the process of collecting oil from a water mirror.

A device for collecting oil and oil products from the surface of the water, comprising a housing made in the form of a cone limiter with a cone to the bottom, inside of which there is a swirler mounted on a shaft inside the housing along its axis, has a special drive, pipeline, pump, floats (RF Patent 1516578 )

This device also contains a lot of devices, hardware-intensive, difficult to construct, require a special drive, gear pump, speed control of the swirl drive.

A known installation for collecting and pumping from a liquid surface a substance that is not miscible with it, floating in the form of a thin film on its surface, which is a platform held by floats and attached by means of an anchor device to the bottom of the reservoir to be cleaned (RF Patent No. 458136). A device for collecting a film of substance and a device for collecting and pumping the collected substance are mounted on the platform.

The device for collecting the film consists of a swirler driven into rotation through a vertical shaft from an electric motor mounted on the platform, a cylindrical cup attached to the platform with rods and having a horizontal bottom partially overlapping its lower section with the possibility of movement in height.

The device for the selection and pumping of the collected substance is made in the form of a suction pipe, the lower end of which is located at the site of the formation of a funnel and connected to a floating reservoir (sedimentation tank) for collecting a substance floating in the form of a thin film by means of a pipeline connected to a pump mounted on the platform.

This device is also quite apparatus-intensive, difficult in design and maintenance, requires adjustment of the horizontal movement of the bottom of the glass, which requires lifting the entire platform together with its anchor devices for attaching the platform to the bottom of the reservoir to be cleaned, require a special drive, pumping (self-priming) pump requires installation and adjusting it to a specific, required performance.

A device for collecting oil from a water surface is known, comprising a float with a conical collector and a suction nozzle installed in it and a closed pipe above it, with holes located obliquely to the horizontal plane and directed into the collector, where compressed air directed to the liquid (water) is supplied and providing movement of light substances, such as oils, into the collection tank and then through the suction pipe into a special storage tank (RF Patent No. 402609).

This device requires an additional stand-alone compressor or a controlled compressed air supply system, because under the influence of air jets, a decrease in water level may form on the outside of the collector, which prevents the absorption of a thin layer of oil products into the collector located above the separation phase, and to eliminate this drawback, the collector must will immerse more in water, which reduces the efficiency of the intake process and the operation of the device, in addition, the device requires a special pump, for example For example, a rather expensive vacuum suction pump entrained in oil and water in a cone-shaped collector can interrupt the operation of many other pumps that supply liquid from the funnel to the required height of the collection tank.

A device for collecting oil products from the surface of the water, we have taken as a prototype (RF Patent 2049202, IPC ЕВВ 15/10 (1995.01)), contains an oil collecting funnel, the lower tapering part of which is connected to a flexible suction pipe, equipped with a lid located above the oil collecting funnel , and vertical guides, the lid is made with a flange, the inner diameter of which is larger than the diameter of the oil collection funnel, and is equipped with an exhaust fan, and the cover and oil collection funnel are installed with the possibility of ver vertical movement and fixation on vertical guides rigidly fixed at the bottom of the reservoir.

Such a device (prototype, RF patent 2049202), before the device we offer, also has its drawbacks.

A prototype device requires a lot of its devices. So you need an exhaust fan with an electric drive, the supply of electricity to it and a control device for its performance. A flexible oil gathering funnel is connected to the suction nozzle of the funnel and to the nozzle of the capacity of the vacuum machine or to the nozzle of a centrifugal self-priming pump, the cost of which is quite large. To regulate, tune, monitor and control the processes of suction of petroleum products when the device is immersed, for example, into fairly deep factory oil traps through the inspection tight window of the fan cover is practically difficult and not convenient. Fixing the funnel and lid on vertical guides when immersing the device, for example, in the same deep factory oil traps or in any other reservoir or in a large capacity not completely filled with liquids, is also difficult and not convenient. In open water bodies, including open oil traps, various pollutants, for example, in the form of sand, earth and others, can get on their surface from the wind from the wind. Once oil and oil products come to the surface, they reduce their fluidity, oil products coagulate and coarsen, picking them up with a prototype device may be difficult or may require reconfiguration. The same thing can be observed when the temperature drops at different times of the year. If there is unrest on the surface of the reservoir or in the same open oil traps, from the wind, as well as during precipitation in the form of rain, snow, hail, the prototype device will also fail in operation of the suction vacuum machines or centrifugal self-priming pumps. In this, as in many other cases, settling tanks or gravitational-inertial separators will also be required to obtain clean, oil-free oil and oil products.

The technical result of the proposed utility model is to simplify the design of the device for collecting petroleum products from the surface of the water, from the surfaces of large tanks, from factory oil traps, as well as reducing the cost of the device, increasing its reliability, simplifying maintenance and tuning.

The technical result is achieved due to the fact that the oil collection funnel is made in the form of a welded submersible nozzle, inside of which a submersible drainage pump with a bottom intake of liquids and an upper outlet of oil products collected from the water surface is installed and fastened. The drainage pump is mounted in the immersion nozzle using wooden spacers and bolted. Performing wooden struts of various lengths, we can install (adjust) the required window of various petroleum products sucked from water surfaces. Bushings are attached to the immersion cup by welding, inside of which there are guides located in the required treatment tank (or, for example, in an oil trap). Installation of the immersion nozzle together with the drain pump installed in it at the required level of the treatment tank or oil trap is carried out using the handle for raising and lowering the immersion nozzle. The required level of immersion of the submersible nozzle with the drainage pump is fixed at the required level using the fastening mechanism located above the surface of the water in the oil traps. Pump performance can be controlled by the amount of voltage supplied to it, thereby taking the required layer of various petroleum products from the water surface due to their surface tension and directing them to the required capacity, sump, or for finer cleaning, directing them to the required gravitational inertial separators

In FIG. 1 presents the proposed device for collecting petroleum products from the surface of the water.

Here: 1 - welded submersible glass; 2 - submersible drainage pump; 3 - persistent laying of a submersible pump; 4 guide bushings; 5 - handle for raising and lowering the submersible glass; 6 - guides of a submersible glass; 7 - mounting guides of the immersion nozzle on a working treatment tank or in an oil trap; 8 - fastening mechanism (nut - wing) of the submersible glass at the required level; 9 - electric power cable submersible drainage pump; 10 - hose outlet suction fluid from the pump and supply fluid to the desired capacity; 11 - wooden struts fixing the pump to the glass; 12 - bolt fastening of wooden struts to a submersible glass and the pump; 13 - water; 14 - oil products.

In the proposed device, the oil collecting funnel is made in the form of a welded submersible nozzle 1, inside of which a submersible drainage pump 2 with a bottom intake of liquids and an upper outlet of oil and oil products collected from the water surface is installed and fastened. A stop gasket 3 is installed between the bottom of the immersion nozzle and the drainage pump 3. To the immersion nozzle 1, sleeves 4, handle 5 are fastened by welding. Inside the sleeves 4 there are guides 6 located and fixed in the required treatment tank (or, for example, in an oil trap). The guides 6 are mounted on the surface of the working treatment tanks or in the oil trap by means of fastening mechanisms 7. Installation of the immersion nozzle 1 at the required level of the treatment tank or oil trap is carried out using the handle 5 for raising and lowering the immersion nozzle. Fixing the required level of immersion of the immersion nozzle 1 with the drain pump 2 at the required level is carried out using the fastening mechanism 8. The power supply to the pump is carried out by an electric cable 9, which has double insulation, the outer shell of which is made of oil-benzo-acid-resistant material. Insulation of the electric cable 9 from water, oils, various petroleum products can be carried out, for example, by passing the electric power cable of the pump through the silicone hose of the required size and its adhesive sealing. The intake of oil products 14 from the surface of the water 13 is carried out from the bottom of the pump and is discharged upward through the pump through its nozzle and hose 10 and can direct them to the required capacity, sump or, for finer cleaning, direct them to the required gravitational-inertial separators. The drainage pump 2 is attached to the immersion nozzle 1 by means of wooden spacers 11 and by bolt fastening 12. Wooden spacers 11 can be made in various sizes: length (B) and width (A). Performing wooden spacers 11 of various lengths (B), we can set (adjust) the required window of liquid sucked from the surfaces by dimensions (L × A), thereby regulating the rate of absorption of oil products 14 from the surface of water 13, by an electric pump 2, from the required levels of water surfaces.

The work of the proposed device for collecting oil from the water surface does not require highly qualified personnel. Using the handle 5, the welded immersion cup with the pump 2 installed in it, assembled, is installed in the reservoir with petroleum products to the required depth and is fixed by the fastening mechanism 8 (nut - lamb). The immersion depth of the upper edge of the immersion nozzle must be such that oil and oil products are trapped and flow into the cavity between the immersion nozzle and the drain pump. Turn on the electric cable 9 for powering the pump 2 in the network. The liquid pumped by the pump 2 is sucked in at its lower part and is fed through a hose 10 to the required capacity for receiving liquids. Tank receiving liquids can be made, for example, in the form of a tank - sump. With a sufficiently large deepening of the upper edge of the immersion nozzle in water, the device can capture oil, oil products and water and direct them for a further sufficiently high degree of separation from each other into various gravitational-inertial separators. whose performance can be quite high.

The performance of pump 2 can be easily controlled by the amount of voltage supplied to it, thereby taking the required layer of various petroleum products from the water surface due to their surface tension and directing them to the required capacity, sedimentation tank or directing them to the required gravitational inertial separators and other cleaners.

The pump, openly located in a submersible glass, allows you to visually observe the movement of the liquid sucked in, the intensity of its intake into the glass and pumping. By connecting it to the exit of a transparent silicone hose 10, you can observe the movement of liquids, connect various devices, flow meters and others to it.

The implementation of such a highly efficient and easy-to-use device for collecting oil products from the water surface was made possible thanks to the emergence of new drainage pumps of this type, including the vertical delivery of various pumped liquids. Pumps are made of stainless steel, reliable in operation, have a low cost. They suck well and pump even slightly flowing and contaminated oil and oil products, capture and pump various pollutants that fall onto the surface of the reservoir in the form of sand, earth, soil, plant leaves, and others. Pumps operate reliably in the summer and winter seasons, and can work even with atmospheric precipitation - rain, snow, hail.

Moving and fixing the immersion nozzle with the pump on the vertical guides 6 allows not only to install them in the reservoir to the required depth, but also to install them above the water level, thereby, if necessary, to clear them of possible large contaminants that fall into them, visible branches, dead fish and others that may affect the quality of the collection of oil and oil products from various water surfaces. This also gives access for quick change or replacement of wooden struts 11 with other required sizes.

The manufacture of such a device does not present any difficulties, special materials are not required, pumps of the type RD-DP400 / 5S, RD-DP750 / 5S, pumps of the "Niro" type and others can be used.
