Description

The utility model relates to devices for the removal of sludge and can be used when conducting activities to localize oil spills on rivers during the movement of the sludge on the surface and inside the water stream.

Sludge is an intra-sea ice that has surfaced or is brought deep into the stream in the form of clods, carpets, wreaths and ice clusters.

The problem of localization of an oil spill in open water in the presence of sludge and loose accumulations in the transitional aggregate state of water is the protection of summer booms installed to localize oil spills from sludge, the load from which causes damage to them.

The design of summer booms is not designed to work in such conditions, therefore, for successful oil localization during this period, it is necessary to protect them from sludge and snow.

The prior art device for protecting water intakes from ingress of sludge according to the patent for invention RU 2182619 C1 (publ. 05/20/2002, IPC: E02B 5/08, E02B 9/04), which is taken as a prototype.

The device contains a volumetric filter cartridge, consisting of a metal rectangular contour frame with grooves on the inner side, in which watertight filter plastic pipes are tightly installed. The volumetric filter cartridge is located in the guide groove design of the inlet window of the flooded water intake head of the intake.

The disadvantages of this device is the need for stationary installation, the inability to use without additional mounting supports, which requires a lot of time.

The objective of the utility model is to develop a device with a simple construction for delaying sludge, which is installed in front of summer booms upstream of the boundary of the oil spill.

The technical result consists in creating an operatively installed portable device for protection against sludge.

The problem is solved, and the specified technical result is achieved due to the fact that the device for removing the sludge contains a float made of a hermetically sealed metal pipe; mounting loops mounted on the ends of the float; guide tray welded to the float; a retaining mesh, reinforced at the edges with a contour strip and welded to the entire width to the lower generatrix of the float; ballast connected by welding to a holding grid and contour strips; while the float provides the device with positive buoyancy, and the ballast - vertical stability.

In addition, the specified technical result is achieved in special cases of the implementation of the utility model due to the fact that:

- a float made of a DN 200 metal pipe 10 meters long and 2 mm thick provides the device with buoyancy, in which no more than 35% of the volume of the float is immersed in water;

- ballast made of a metal pipe DN 25 with a thickness of 2 mm and a length of 10 meters, filled with concrete;

- a retaining mesh 10 cm high, made of forged steel, has a cellular structure with a cell cross section of 3 × 3 cm;

- cables and coastal anchors can be used as means of fastening.

In FIG. 1 shows a general view of a device for removing sludge; in FIG. 2 - view from the side; in FIG. 3 - section aa; in FIG. 4 - section BB.

In FIG. 1, 2, 3 and 4 positions marked:

1 - a directing tray;

2 - fixing loop;

3 - float;

4 - holding grid;

5 - ballast;

6 - contour strip.

The device for removing the sludge consists of a guide tray 1 made of impact-resistant material, for example, a longitudinally cut length of a steel pipe.

The guide tray 1 is welded to the float 3, which is a hermetically sealed metal pipe. In a particular case, the pipe has a diameter of 200 mm (DN 200), a thickness of 2 mm and a length of 10 meters. The float provides the device with positive buoyancy so that no more than 35% of its volume is immersed in water.

Fixing loops 2 are welded to the ends of the float 3 for fastening the device to the shore using cables.

A mesh mesh 4 is welded to the bottom generatrix of the float along its entire width, made of material that is resistant to stretching and tearing (for example, forged steel). The edges of the retaining wall 4 are reinforced with a contour strip 6 made of steel.

In a particular case, the height of the mesh 4 is 10 cm, the cross section of the cell is 3 × 3 cm (the larger the cross section of the mesh, the lower the load from water and the more sludge allowed).

Ballast 5 is connected to the holding grid 4 and the contour strips 6 by welding.

Ballast 5 provides vertical stability of the device. Its mass is selected depending on a combination of the following parameters: the speed of the river, the installation angle of the device relative to the direction of the river, the cable cross section, the geometric dimensions of the device, the density of the sludge, the performance of extracting the sludge from the surface of the water.

With the initial data of the parameters characteristic of a typical application of the proposed utility model (on the Khor River in the Far East of Russia, in the Lazo Khabarovsk Territory region): flow velocity - 1.7 m / s; installation angle - 16 °; cable section - 15 mm; sludge density - 950 kg / m ³ , sludge extraction performance, providing a residual volume within the surface of the retaining mesh of not more than 4.3 m ³ - the weight of the ballast should be at least 120 kg.

To fulfill this condition, the ballast 5 is made of a metal pipe filled with concrete, the pipe has a diameter of 25 mm (DN 25), a thickness of 2 mm and a length of 10 meters.

The device for draining the sludge is attached by cables to the coastal anchors.

The claimed device for removing sludge works as follows.

The device is delivered to the river bank. On both banks of the river with the help of coastal anchors through loops 2, the device is rigidly attached to the shore. Ballast 5 provides a submerged state of the device. The guide tray 1 and the holding grid 4, due to the location of the device at an acute angle to the river, direct the incoming sludge to the shore, where the latter is removed by specialized equipment. To increase the area of detention of the sludge, several devices can be used interconnected by means of mounting loops 2.

If necessary, the device is disconnected from the coastal anchors and quickly moves to any place on the river surface.

The prototype device for the retention of sludge was designed and manufactured by Transneft Far East, LLC. His tests showed the necessary mobility when localizing an oil spill according to technology for the summer period during the movement of sludge on the surface and inside the water stream.

In the claimed utility model, an operatively installed portable device for discharging sludge is implemented, which is intended to prepare for the implementation of measures for the localization of oil spills. The device can be installed in a short time in front of summer booms upstream of the line of oil spill localization, which allows for unimpeded work on emergency response.
