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.
