Abstract

The invention discloses a membrane isolated oil product storage and delivery device, which comprises a shell, an oil inlet pipe, an oil outlet pipe and a breathing opening, wherein the inside of the shell is provided with a membrane of which the capacity is larger than that of the shell; the top of the membrane is locally fixed on the top of the shell; the other part of the membrane is separated from the shell; an inner layer of the membrane is communicated with the breathing opening and isolates an inner cavity of the shell from the air; the oil inlet pipe and the oil outlet pipe are arranged on the top or at the bottom of the shell and communicated with the inner cavity of the shell; both the oil inlet pipe and the oil outlet pipe are provided with a valve and a quick coupling; and the top of the shell is provided with a safety valve. The membrane isolated oil product storage and delivery device uses the membrane to isolate stored products and the air, eliminates breathing loss, protects the environment, reduces oil oxidation, avoids mixing of water and the oil products, eliminates oil vapor mixed with the air to improve the safety of storage and delivery and reduce the hazards of fire disasters and explosion, and is favorable for resisting an external force such as impact due to a flexible structure. Moreover, the membrane isolated oil product storage and delivery device can be used for vertical oil storage tanks, horizontal oil storage tanks, modification of the vertical oil storage tanks, reserve tanks and modification of the reserve tanks, is simple and easy to modify, environment-friendly, safe and energy-saving, and eliminates a large part of current oil vapor pollution when the membrane isolated oil product storage and delivery device is implemented.

Description

Technical field

[0001] The invention relates to a low-pressure, normal-pressure storage and transportation device for oil products, which belongs to the technical field of oil storage and transportation. Background technique

[0002] At present, the transshipment, storage and use of oil products include pipeline transportation, railway tanker and automobile tanker transportation, tanker transportation, oil depot storage tank storage, gas station storage, equipment tank storage and other links. Oil depot storage tanks (vertical tanks) use floating roof technology to reduce breathing loss by more than 90%, but because floating roof technology is difficult to apply to horizontal tanks, horizontal tanks generally have large breathing loss, resulting in oil evaporation Loss, quality decline and environmental pollution, there are fire and explosion safety hazards.

[0003] Let's take gasoline as an example.

[0004] According to the instructions compiled by the Safety and Enviro...
