Problems solved by technology
[0004] Affected by factors such as temperature changes, oil in and out of the oil tank, a large amount of oil and gas will be generated between the storage medium and the double-disk floating roof bottom plate, due to the large local deformation of the floating roof and bottom plate when welding, resulting in oil and gas accumulation When the storage medium in the tank shakes, it will easily cause large fluctuations in the floating roof, which is not conducive to the smooth operation of the floating roof

The invention discloses a double-deck floating roof, and relates to the technical field of oil and gas storage and transportation. The double-deck floating roof comprises a top plate, a bottom plate,a truss structure and an outer side plate, wherein the top plate and the bottom plate are arranged opposite to each other; the truss structure is used for connecting the top plate and the bottom plate; the outer side plate is used for connecting the edge of the top plate and the edge of the bottom plate; both the top plate and the bottom plate are round; and the side face, away from the top plate,of the bottom plate comprises a conical convex surface portion concentric with the bottom plate. During use of the double-deck floating roof, an annular gas storage space is formed among a storage medium, the conical convex surface portion and a tank wall, formed oil gas diffuses into the annular gas storage space, and gas pressure in the annular gas storage space can evenly act on the double-deck floating roof to keep the double-deck floating roof stable, so that floating roof shaking caused by the fact that the oil gas is gathered in a local area is avoided.
Description
technical field [0001] The invention relates to the technical field of oil and gas storage and transportation, in particular to a double-disc floating roof. Background technique [0002] Vertical cylindrical steel floating roof storage tank is the main equipment for storing petroleum products, and occupies an important position in petroleum storage and transportation and petroleum reserves. According to Chinese standards, the volume of a single tank for storing Class A and B liquids is greater than or equal to 5×10 4 m 3 The floating roof storage tank should adopt steel double disc floating roof. [0003] The double-disc floating roof is usually composed of two discs, the top plate and the bottom plate, which are connected by radial brackets. When in use, the double-disk floating roof is installed in the open oil tank as the tank roof. The floating roof can float on the surface of the storage medium and rise and fall with the change of the liquid level. [0004] Affected...
