Description

and it was made together with an internal water collector, while the working agent is placed under the oil product and water is used as the working agent.

Moreover, the tank roof is made in the form of a pontoon with a shell, in the center of which is placed a vertical hollow cylinder for discharging the working agent from the tank or sucking it into the tank, and around the perimeter the pontoon is provided with an elastic seal, while the working agent is placed above the oil product working agent used is air.

FIG. 1 shows schematically a reservoir for storing oil and petroleum products, a section; in fig. 2 - storage tank for slightly evaporated oil products -.

The reservoir consists of base 1, which includes cylindrical reinforced concrete shells 2 of large diameter with bottom 2 and bowls 4, which are connected by pipes 5 to form communicating vessels used for storing oil and oil products from the shells of the system. The bottom 6 has an outer annular support flange 7. The cylindrical body 8 has a radial groove 9, an anchor horizontal flange 10 for anchoring the enclosure and sealing it in the outer annular support flange of the bottom, made in the form of a plate-grillage. In the tank placed the separation of the veil 11, also the veil 12 and in the shells. These curtains are designed to prevent the oil product from mixing with the working agent (water or air). .

In one embodiment, the bottom 6 is made of a support shoe 13 in the center, on which a vertical post 14 is supported with an opening 15 in the plane of the bowl of the bottom 16. The rear end is spherical with a recess 17 in the center 18, in which an opening 19 is made, the coating is hermetically connected to the stand. An internal water collector 20 is made on the bottom of the tank, and an external 21. Around the perimeter of the tank. In addition, the tank has a water line 22 connected to the shell bowls and a water line 23 connected to the bowl and passing through its body, a numbered common pump 24 and individual spar fittings 25 and 26 for filling the tank with water, a water supply siphon 27 for self-leveling pressure in the shells, which with its knee reaches the top of the shells, and with its ends connects the bowls of the shells and the outer sump in a plane of its bottom The pipeline 28 is connected to the top of the shells and passes through the bottom, the pipeline 29 is connected from above to

coating. It passes through the Bottom body and inside the rack there is a common pump 30 and individual valves 31 and 32 for filling the tank with oil or petroleum products. A light roof 33 is installed above the recess in the coating, with a support ring 34 with bearing fixers-tables 35 and an annular gasket-seal 36 inside, and the light roof contains a socket 37 for communication with the atmosphere of the space ngsch stand.

The tank works as follows. .

The outdoor water collector is filled with water. The shut-off valves 25 and 26 of the water pipes are alternately opened and the pump 24 is actuated to fill the volume of the basement shells of the reservoir first, and then its cylindrical body, while the separation curtains 38 of the shells and the body 10 float on the water and take the extreme upper position, after which it closes shut-off fittings for water pipelines; shut-off valves 31 and 32 of oil pipelines alternately open and the pump 20 is activated to fill the volume of basement shells and then the volume of cylinders with oil The reservoir hull at the same time as water is discharged (discharged) through water mains 22 and 23. At the same time, the oil product pre-filled areas above the separation curtains 38 with complete air discharge from them, and a part of the water volume is left in the shell cups due to the displacement of water left in shells through the water supply siphon 27 to the external water collector or self-suction in the opposite direction and the cylindrical body of the tank due to the displacement of water from the bottom of the tank when the ambient temperature fluctuates between the levels of o. (level of water column in the rack, corresponding to the level occupied by water at the highest temperature of outdoor air) and L the formation of a gas space in the case of both small tank breaths and large breaths.

Claims (2)

In the second variant, removable roof 39 includes lower carrier 40 and upper anti-atmospheric 41 thin non-metallic shells with a hollow element 42 in the center between them, through which the inner area of the tank with the atmosphere is connected, and the outer ring element 43, the outside of which is made a groove 44, an annular elastic chamber-seal. 45, which is mounted between the groove 46 of the tank body and the grooves of the outer ring member with the rotary sealing body 47 inside to seal the annular joint between the tank body and the removable roof. . The volume of the basement shells and the tank body is completely filled to the design level of oil product storage, and the separation curtains, like the body shells and body, float on the stored oil product, excluding the contact of the stored product with air and the atmosphere thereby evaporating, and the air from the area above the curtains a black hollow element emerges and openings 48 with tunnels 49 in the upper part of the basement shells. When the tank is emptied, the curtains move downward all the time on the surface of the oil product, and the element and openings with tunnels go through the tank through the floors and are in contact with the pontoons 18, excluding the evaporation of the stored oil into the air. The use of the invention provides almost complete elimination of oil product losses due to the absence of air contact with it due to improved sealing with the tank body, elimination of environmental pollution, a significant reduction in metal consumption for roofing, bottom and pontoon reduction of fire hazard, increase in tank capacity due to height it is due to the possibility of transfer to the soil through the shell of the foundation of significant specific pressure. Claims 1. A reservoir for storing petroleum and petroleum products, including a foundation, a bottom, located below groundwater level, a body, and a cover. about t and l. including the fact that, in order to reduce the material intensity and increase the capacity of the tank by increasing its height, pound; The vessel’s reservoir is made of hollow cylindrical reinforced concrete shells interconnected with the source of the working agent and with an oil pipeline, while the bottom of the tank is made in the form of a grillage plate and hermetically connected with the shells, and the casing and each shell are provided with horizontally placed separation curtains dividing the body and the shells into compartments, one of which is filled with petroleum products, and the other with a working agent. 2. The reservoir of claim 1, about tl, which is due to the fact that, in order to reduce the loss of stored oil product from evaporation, it is provided with outer annular and internal water collectors connected by pipelines, and the coating is made spherical with a CIM with a recess in the center in which an aperture is made, with the tank filled with a hollow vertical stand filled with water and expanded in its central part, and the stand is tightly connected to the aperture and made together with an internal water collector, while the working agent is placed under the oil product and water is used as a working agent. 3. The reservoir according to claim 1, characterized in that, in order to reduce the loss of the stored weakly evaporated oil product, the reservoir crank is made in the form of a pontoon having a shell in the center of which is placed a vertical hollow cylinder for discharging the working agent from the reservoir or sucking it into tank, and around the perimeter of the pontoon is equipped with an elastic seal, while the working agent is placed over the oil product and air is used as the working agent.
