RU2507359C2 - Reservoir with protective wall - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: reservoir with a protective wall comprises the main inner reservoir designed for storage of a product, including a wall, a bottom, a roof and a protective wall with an attached additional bottom. Between the wall of the main inner reservoir and the protective wall in the bottom part of the space between them there is a device of spatial links installed and fixed to walls, comprising stiffening rings, radial and vertical spacers and diagonal links.

EFFECT: increased stiffness of a reservoir.

Description

The invention relates to vertical cylindrical tanks for storing oil and oil products.

Known vertical cylindrical reservoirs for storing petroleum products, consisting of a main internal reservoir intended for storing a product, including a wall, bottom, roof, and a protective wall with an additional bottom attached to it (see, for example, a Vertical steel cylindrical tank with a protective wall, Catalog OJSC Kurgan chemical engineering plant “Kurganhimmash”, p. 12, http://khm.zaural.ru/download/katalogi-dlya-skachivaniya-tehnicheskie/oborudovame-magistralnyh-truboprovodov.pdf; Vertical steel welded tank with a protective Tenko, Catalog ZAO "AP Saratov plant tank metal structures», http://www.rmk.ru/rus/products.php?id=2#2); patent RU 59674, IPC E04H 7/00, publication date 12/27/2006; patent RU 37748, IPC E04H 7/00, publication date 05/10/2004.

The disadvantage of analogues is the lack of rigidity of the interstitial space of the reservoir in seismic regions.

The closest analogue is known to be a tank with a protective wall, consisting of a main internal tank designed to store the product, including a wall, bottom, roof, and a protective wall with an additional bottom attached to it (see, for example, the description of the tank with a protective wall in the STO standard -CA-03-002-2009 “Rules for the design, manufacture and installation of vertical cylindrical tanks for oil and oil products”, p. 193, Fig. A.17.1).

The disadvantage of the closest analogue is the lack of rigidity of the inter-wall space of the reservoir in seismic areas, causing the possibility of overturning of the main reservoir and requiring its anchoring during construction. However, the anchoring of the main reservoir leads to a violation of the tightness of the protective bottom in the interwall space under seismic impact and in some cases under strong seismic impact may not be sufficient to ensure the rigidity of the interwall space of the reservoir.

The technical result is to increase the rigidity of the inter-wall space of the tank with a protective wall and increase the stability of the tank in seismic areas.

The essence of the technical solution lies in the fact that the tank with a protective wall consists of a main internal tank designed to store the product, including a wall, bottom, roof, and a protective wall with an additional bottom attached to it, and differs from the closest analogue in that between the wall the main internal reservoir and the protective wall in the lower part of the space between them are installed and attached to the walls of the spatial connection device, consisting of stiffening rings, radial and vertical spacers and diagonal ties.

The essence of the technical solution is illustrated by drawings, which depict:

figure 1 is a view of the tank in plan;

figure 2 is a view of the tank in section aa;

figure 3 is a view And the device of spatial relationships in the interwall space.

The tank with a protective wall comprises a wall 1, a bottom 2 and a roof 3 of the main inner tank, a protective wall 4 and an additional bottom 5 attached to it (Figs. 1, 2).

In the inter-wall space between the wall 1 and the protective wall 4, a spatial connection device 6 (Fig. 1) is installed and attached to the walls 1 and 4, consisting of stiffening rings 7 and 11, vertical struts 8 on the wall 1 and the protective wall 4, horizontal struts 9 and diagonal ties 10 (figures 1, 2 and 3). Rigidity rings 7 and 11 can be attached to the walls 1 and 4 by welding. The vertical struts 8 on the wall 1 and the protective wall 4 can be attached to the walls 1 and 4 by welding. Horizontal struts 9 can be attached to stiffening rings 7 and 11 by welding or bolted joints. Diagonal ties 10 can be attached to stiffening rings 7 and 11, to vertical struts 8 and between each other by welding or bolted joints. Each ring of stiffness 7 and 11 can be made of separate at least two parts (for example, two half rings or four quarters of the ring) by welding or bolting. The installation of all the above mentioned details of the spatial communication device 6 should be carried out in a tank on the territory of the Russian Federation in accordance with the standard STO-SA-03-002-2009 “Rules for the design, manufacture and installation of vertical cylindrical tanks for oil and oil products”.

The use of the claimed tank with a protective wall increases the stability of the tank from tipping over, because the area of its rigid support on the base increases by increasing the rigidity of the inter-wall space of the tank with a protective wall, allows you to refuse to install anchors on the main tank, and in some cases, if necessary, allows you to transfer the anchoring to the protective wall of the tank.
