AI Technical Summary

Problems solved by technology

Manholes, oil inlets and outlets, vent holes, and oil measuring holes are all set on the oil tank. There is always a gas space on the oil surface in the tank. Since the stored products are easy to volatilize, the capacity of the storage tank is relatively small, and the stored products in the tank enter and exit frequently. According to some field experience, when the temperature is 20 degrees and the atmospheric pressure is normal, 1 kg of gasoline vapor will be discharged into the atmosphere for every cubic meter of gasoline. If the temperature is higher than 20 degrees, more oil vapor will be discharged into the atmosphere. ; At the same time, if the oil tank wall is damaged, the outflow of oil can easily lead to the danger of fire
As a result, the volatilization loss of stored products is serious, polluting the environment, and increasing the risk of fire and explosion

Embodiment 1

[0020] Embodiment 1: (the cross-section of the outer and inner walls of the oil tank is rectangular, and the oil inlet and outlet pipes are arranged at the upper end of the tank body)

[0021] This embodiment 1 includes that the oil tank is composed of an outer wall cylinder 1, an outer wall flat cover 4, an inner wall cylinder 2, and an inner wall flat cover 5. The cross sections of the outer wall cylinder 1 and the inner wall cylinder 2 are both rectangular, and the outer and inner wall cylinders A reinforcement ring 3 is provided in the interlayer.

[0022] It is welded on the top of the tank with air vent 6, manhole 7, oil inlet pipe 8, oil outlet pipe 9 and oil measuring hole 10. There are 2 ventilation holes 6, so that the upper space of the inner floating roof can convect gas, and good ventilation conditions are arranged to prevent oil and gas from accumulating to the limit of explosion here. A floating inner floating roof 11 with a rectangular cross-section floating i...

Embodiment 2

[0023] Embodiment 2: (the cross-section of the double-wall cylinder of the oil tank is square, and the oil inlet and outlet pipes are arranged at the lower end of the tank body)

[0024] The oil tank of this embodiment 2 is composed of an outer wall cylinder 1, an outer wall flat cover 4, an inner wall cylinder 2, and an inner wall flat cover 5. The cross sections of the outer wall cylinder 1 and the inner wall cylinder 2 are both square, and the inner floating roof 11 It is a pontoon type made of aluminum plate with a square cross-section. The oil inlet pipe 8 and the oil outlet pipe 9 are arranged at the lower end of the tank body. The height of the pillar 14 is higher than the height between the bottom of the tank and the oil outlet 9.

[0025] Other structures are with embodiment 1.

Abstract

The invention discloses a horizontal double-walled double-rectangular cylindrical internal floating roof oil tank, which comprises: a tank body, a flat cover, a ventilation hole, a manhole, an oil measuring hole, an oil inlet pipe and an oil outlet pipe. The tank body is composed of outer and inner double walls, the cross sections of which are rectangular or square, and an inner floating roof is floating inside the inner wall. The lower surface of the inner floating roof has inherent pillars. An electrostatic discharge device is installed between the inner floating roof and the tank body, a soft sealing device is installed around the inner floating roof, the manhole is welded on the tank roof, and the oil inlet pipe and the oil outlet pipe are arranged at the upper end of the tank body or at the lower end of the tank body. The invention can save energy, reduce the loss of oil products, and reduce the loss of oil products by 95% compared with ordinary horizontal oil tanks; it is safe to use and reduces the risk of fire and explosion; protects the environment; and weakens the corrosion of oil products on the tank body ; Since the evaporation of the oil is greatly reduced, the quality of the oil is also guaranteed, and the structure is simple, practical and effective.

Description

technical field [0001] The present invention relates to an oil tank, in particular to an atmospheric pressure horizontal storage tank used in oil depots, gas stations, automobile oil tank cars, railway oil tank cars and other storage or transportation bulk volatile liquid oil products and chemical products . Background technique [0002] Horizontal oil tanks are often used in small distribution oil depots, rural oil depots, military field oil depots or enterprise-affiliated oil depots, gas stations, and tank parts of tank trucks. The current horizontal oil tanks are basically horizontal cylindrical steel oil tanks . Manholes, oil inlets and outlets, vent holes, and oil measuring holes are all set on the oil tank, and there is always a gas space on the oil surface in the tank. Since the stored products are easy to volatilize, the capacity of the storage tank is relatively small, and the stored products in the tank enter and exit frequently. According to some field experienc...
