Description

In known storage tanks for petroleum products, both underground and surface types, consisting of a reinforced concrete hull with an inner iron sheath, the space between the reinforced concrete hull and the iron sheath is usually filled with water in order to equalize the external pressure n of the inner pressure on the metal sheath, and under the layer stored petroleum products are also arranged for water at the bottom of the tank.

When supplying oil tanks with such water bypas, there is, however, the task of reducing to a minimum the possibility of mixing oil products with water in the tank when the tank is filled with oil or when it is released.

According to the invention, a perforated iron pipe vertically mounted above the water jacket is used in such an oil storage tank.

The drawing shows a schematic of the proposed device.

The tank 1 itself is made of concrete, reinforced concrete, or stone with gunned inside surface. When concreting or laying the tank, metal pins 2 are placed into the concrete. After removing the formwork, spacer sleeves 3 of the appropriate length are put on the pins 2 to create an interstitial space. Then, the pasted pins 2 hang the prepared metal sheets 4 and weld them. Sheets can be welded to the joint, overlapped or with a lining, depending on the fit of the sheets and the convenience of work. The protruding ends of the pins 2 are trimmed and brewed.

Thus, the inner surface of the tank is obtained lined with iron sheet.

The bottom 5 of the tank, also made of sheet iron, is placed on the concrete pad 6 (slab). Facing the walls attached to the walls of a reinforced concrete or stone tank with the help of pins 2 and bushings 3 creates an interstitial space 7 of the desired size, in the order of 1-5 cm.

Under the metal bottom 5 of the reservoir, when the concrete is wetted, 9 is made into which metal w, infrared 8 (hydraulic buffer) of the required volume is inserted.

On metallic chic 8 (hydraulic buffer), pipe 10 is placed with a height equal to the height of tank 1.

The walls of the standing pipe 10 along the entire height, with the exception of the first meter from the bottom, are provided with round visors.

The holes of the vertically standing pipe 10 are located at a distance of about 1 m from the bottom with the aim that the suspended particles precipitated during the sedimentation of oil product were placed at the bottom of the tank and did not penetrate into the hydraulic buffer.

The hydropower buffer 8 with a tube AND of the corresponding diameter is connected to the interstitial space 7 and a valve 12 is placed on it. The hydraulic buffer 8 is also connected to the pipe 13 with a space 14 between the metal bottom 5 and the cushion blanket 6. On the pipe 13 there is a valve 15, which It is always closed and opens only when you want to check the tightness of the bottom 5 metal obo, yuchki.

Next to the reservoir 1, from the outside of it, a viewing well is made, in which a pipe is supplied from the water supply system to the inter-sectional space and a water-glass is placed. When the tank is empty, water is poured into the interstitial space 7 through the supply valve in the manhole until it fills the hydraulic buffer 8 and begins to overflow through the openings of the vertical pipe 10. After that, the tank is ready to receive oil.

The petroleum product flowing into the tank with beats at any speed and in any quantity smoothly passes through the orifices of the pipe 10 into the tank and creates hydrostatic pressure in the hydraulic system 8. As the level of petroleum product in the tank increases, water from the hydraulic buffer 8 will be squeezed out and flow into the interstitial space 7 .

When emptying the tank from the oil product, also at any speed and in any quantity, the vortex movements do not spread to the oil product in the pipe 10, and since this position is the column:: (the liquid in the pipe 10 will be slightly higher than the liquid level in the tank .

This oil product PZ of the vertically standing pipe 10 will flow freely through the holes.

Thus, any movement of the petroleum product with water is excluded.

Inspection hatches (manholes), breather valves, gauging devices, and the like, the equipment tank is supplied as usual.

Such a tank is reliable during operation and, at the same time, makes it possible to check and detect (adhesions of cracks in the metal lining).

Checking the tightness of the seams is done as follows: to check the bottom when the tank is empty, the valve 12 on the pipe 11 connecting the hydraulic buffer 8 with the interfacular space 7 is closed, and the valve 15 on the pipe 13 connecting the hydraulic buffer 8 with the space 14 opens.

In the hydraulic buffer 8, water or kerosene is poured and held at the required pressure. Water or kerosene, penetrating the space 14 between the concrete pad 6 and the metal bottom. 5 and being under pressure, will seep into cracks, if any, in the metal floor.

Water or kerosene is removed from the hydraulic buffer 8 with a manual pump.

To check the density of the side walls, when the tank is empty, the valve 12 on the pipe 11 connecting the hydraulic buffer 8 to the interwall space 7 is closed, and the valve 15 on the pipe 13 closing its connection with the space 14, and the hydraulic buffer 8 is filled with water. Kerosene is poured into the interstitial space 7 to a height of about one meter, after which the valve 12 on the pipe 11 connecting the hydraulic buffer 8 to the inter-step space 7 is opened. Thereafter, water is gradually poured into the tank, which, as it passes through the hydraulic buffer 8 into the interstitial space-7, gradually raises a layer of kerosene, which leaks out

in the existing cracks of the metal cladding. The cracks detected in this manner are noted and then repaired.

The hydraulic buffer is made of sheet iron in the shape of a parallelepiped or cylinder, no more than one meter high.

The top cover 16 of the hydraulic buffer 8 is sloped. A slope is attached thereto so that during the filling and emptying operations in the hydraulic buffer 8, no air or oil is retained.

The subject matter of the invention.

A tank for storing petroleum products, consisting of an outer stone or reinforced concrete body and inner iron shell with the possibility of filling the space between the walls and the bottom of the body and shell as well as the presence of a water cushion inside the shell under the layer of stored petroleum products, characterized in that In order to calm the movement of the water under the oil products, a perforated iron pipe 10 vertically mounted is attached to the water cushion.
