Description

Tank for hydrocarbon storage

OBJECT OF THE INVENTION

The present invention, as expressed in the statement of this specification, refers to a hydrocarbon storage tank that integrates a characteristic fixed drainage device for extracting the water that accumulates in the lower part of the tank.

By extension, the fixed drainage device is also applicable to any substance other than hydrocarbons that cannot contain either dissolved or suspended water, nor emulsified.

Thus, the objective of the invention is to eliminate the water accumulated at the bottom of the tank by means of the characteristic fixed drainage device incorporated into the tank, so that it is not necessary to use independent equipment to extract the water accumulated at the bottom of the tank. deposit, as conventionally occurs.

BACKGROUND OF THE INVENTION

At present, the water that accumulates in the funds of the hydrocarbon storage tanks is extracted with independent pumping equipment, so that each time it is necessary to extract that water from the bottom of the tank, it is necessary to mount the independent equipment by accessing inside the tank through its mouth or manhole, always trying to find the lowest point of the bottom to extract all the water as much as possible. In sloping deposits it is easier because water tends to accumulate in the lower areas. Currently the elimination of this water is essential, especially with the arrival of new fuels that do not admit its presence to the market.

This operation is quite uncomfortable and entertaining, being sometimes difficult to find the lowest point of the bottom to get the total extraction of wastewater accumulated at the bottom of the tank.

DESCRIPTION OF THE INVENTION

In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a hydrocarbon storage tank comprising a housing that incorporates a manhole that communicates the inside of the housing with the outside of that housing.

It integrates a fixed drainage device of the residual water that accumulates in at least a low area of the bottom of the tank, the fixed drainage device comprising a circuit comprising at least one pipe, one of whose ends reaches the low zone of the bottom of the tank , while an upper end of such a circuit is located outside the tank above it, a terminal connector connecting a device for extracting waste water from the tank, or any other sealing element being fixed on that upper end of the pipe .

An internal section of the pipe of the fixed drainage device is housed inside the housing, this internal section being embedded in a laminar lining that covers the internal face of the tank housing, although it is also possible to arrange the pipe in surface mode, adhered with conventional, mechanical or chemical means.

The pipe of the fixed drain tank passes through an upper through hole of the housing wall, a portion of the fixed drain device pipe fitting tightly in such upper through hole.

The fixed drainage device comprises in a first embodiment a circuit formed by a single pipe whose lower end reaches the lowest area of the tank.

In a second embodiment, the fixed drainage device comprises a circuit formed by two branches that converge in a common section, whose free end integrates the terminal connector, while the lower ends of the two branches reach the lowest areas of the tank.

With the fixed drainage device, it is no longer necessary to have independent equipment to suction the waste water or manual actions, that is, operators that have to be introduced into the tank to suction the waste water through suction hoses.

Next, in order to facilitate a better understanding of this descriptive report and forming an integral part thereof, some figures are attached in which the object of the invention has been shown as an illustrative and non-limiting nature.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1.- Shows a schematic view of the hydrocarbon storage tank that integrates a characteristic fixed drainage device to extract the accumulated residual water at the bottom of such a tank.

Figure 2.- Shows a view similar to the previous one where a second embodiment of the invention is represented.

Figure 3.- Shows a sectional view according to section A-B of the previous figure.

DESCRIPTION OF AN EXAMPLE OF EMBODIMENT OF THE INVENTION

Considering the numbering adopted in the figures, the hydrocarbon storage tank contemplates the following nomenclature used in the description:

1.- Housing 2.- Laminar lining 3.- Man's mouth 4.- Floor 5.- Arcade 6.- Mouth 7.- Circuit 8.- Circuit 8a.- Branch 8b.- Branch 8c.- Common section 9. - Terminal connector 10.- Extraction device 10a.- Front pipe 10b.- Drive pump 10c.- Back pipe 11.- Container 12.- Upper through hole drilling.

The tank comprises a carcass 1 covered by its internal face by means of a laminar lining 2, the carcass 1 incorporating a manhole 3, through which the interior of the tank is accessed, the fuel being introduced and extracted through that mouth of man 3.

The tank is buried under the floor 4, the manhole 3 being located inside a casket 5 that connects at its bottom edge with the shell 1 of the tank, while its upper edge constitutes a mouthpiece 6 flush with the floor 4 and in which attaches an access cover not shown in the figures.

Starting from this premise, the tank integrates a fixed drainage device of the residual water that accumulates at the bottom of the tank, said fixed drainage device comprising a circuit 7-8 according to two different embodiments.

In a first embodiment, circuit 7 comprises a single pipe, an internal part of which is embedded in the sheet lining 2, so that a lower end of said pipe reaches the bottom of the tank, while an upper end of the The pipe has a terminal connector 9 located inside the casing 5 but outside the casing 1, connecting with such a terminal connector 9 an extraction device 10 that has an anterior pipe 10a that plugs into the terminal connector 9, a pump discharge 10b and a back pipe 10c that flows into a container 11 to collect the suctioned wastewater from the bottom of the tank.

In a second embodiment of the invention shown in Figure 2, the circuit 8 of the fixed drain device comprises two branches 8a-8b that converge in a common section 8c, whose free end integrates the terminal connector 9.

In this second embodiment, the two branches 8a-8b, as well as the confluence zone with the common section 8c, are embedded in the laminar lining 2. In both embodiments of the invention the tank is affected by an upper through hole 12

where a portion of circuit 7-8 is tightly adjusted to communicate the inside of the tank with the outside.
