Abstract

The invention discloses a membrane isolating type oil storage and transportation device, comprising a casing, an oil inlet pipe, an oil outlet pipe and a breathing hole, wherein the casing is internally provided with a membrane the volume of which is larger than that of the casing, the top part of the membrane is partially fixed on the top part of the casing, the rest part of the membrane is separated from the casing, and the inner layer of the membrane is communicated with the breathing hole and isolates the inner cavity of the casing from air; and the oil inlet pipe and the oil outlet pipe are arranged on the top part or the bottom part of the casing, are communicated with the inner cavity of the casing and are all provided with a valve and a quick connector respectively, and the top part of the casing is provided with a safety valve. The membrane isolates storage objects from air, thus eliminating breather loss, protecting environment, reducing oil oxidization, avoiding water from being mixed with oil, removing oil steam mixed with air so as to improve safety of storage and transportation, and reducing risks of fire and explosion occurrence. Due to the flexible structure, the invention is favor of resisting external force influence such as impact and the like, is suitable for transformation of vertical and horizontal oil tanks, vertical oil tank and standby reservoir, wherein the transformation is simple and feasible, has the advantages of environment protection, safety and energy conservation, and can eliminate the majority of current oil steam pollution after being 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...
