Three-layer oil tank

Abstract

The invention discloses a three-layer oil tank, comprising a tank wall. The three-layer oil tank is characterized in that the tank wall comprises, from outside to inside, an outer-layer tank wall, an inner coating formed on an inner surface of the outer-layer tank wall, a first three-dimensional fabric layer formed on the inner coating and having an interlayer space, a second three-dimensional fabric layer formed on the first three-dimensional fabric layer, a glass fiber reinforced plastic layer formed on the second three-dimensional fabric layer, an anti-leakage layer formed on the glass fiber reinforced plastic layer and a conducting layer formed on the anti-leakage layer. The three-layer oil tank of the present invention has two layers of interlayer spaces; transformation into the three-layer wall storage tank is performed on the basis of an existing single-layer wall storage tank, and an installation space thus is provided for the installation of a leakage monitoring system; further, the strength of the oil tank is also improved, and even though the outer wall is corroded completely, the oil tank still can be used continuously.

Description

technical field [0001] The invention relates to a three-layer oil tank, which belongs to the field of gas station safety and environmental protection equipment. Background technique [0002] At present, most of the underground oil tanks used in gas stations in my country are steel single-layer tanks. After long-term use, leakage may occur due to internal water corrosion and external soil corrosion. The leaked oil will cause damage to groundwater and soil. Pollution endangers human water safety. Therefore, controlling the leakage of underground oil tanks and preventing pollution is an important content of environmental protection. In developed countries such as Europe and the United States, the leakage control of underground oil tanks has long been listed as a national environmental protection law. [0003] In my country, after oil and gas recovery is listed as a national mandatory standard requirement to achieve air quality control, the "Gas Station Leakage Pollution Contro...

AI Technical Summary

Problems solved by technology

Among these control methods, the liquid level meter method is a low-level leak detection method, because once a leak is detected, the underground environment has actually been polluted; the anti-seepage pool method and the oil tank replacement method can achieve a better environment. control, but the cost is expensive, the project volume is large, and the business must be closed during the construction period, resulting in joint business losses
