Embodiment 1

[0028] Such as figure 1 As shown, a high-performance composite material double-walled oil storage tank includes a tank body 1, an operation manhole 2 and an online monitoring well 3 are arranged on the tank body 1, and carbon fiber fabrics are arranged on the inner wall of the inner tank body layer 1-2 Composite formed lining layer 1-1.

[0029] There is a gap between the inner tank layer 1-2 and the outer tank layer 1-4, and an online monitoring structure layer 1-3 formed by glass fiber three-dimensional fabric is arranged in the gap, and the online monitoring structure layer 1-3 is hollow structure.

[0030] The inner tank body layer 1-2 is formed by compounding glass fiber, and the outer tank body layer 1-4 is formed by compounding carbon fiber or / and glass fiber.

[0031] It can be drawn from the above that the tank body 1 of the present invention has a four-layer structure, and the tank body 1 is respectively from the inside to the outside: the first layer is an inner l...

Abstract

The invention discloses a high-performance composite double-wall oil storage tank. The high-performance composite double-wall oil storage tank comprises a tank body, and the tank body is provided with operating manholes and an on-line monitoring well, is of a four-layer structure and sequentially comprises a liner layer formed by carbon fiber fabric composites, an inner tank body layer formed by glass fiber composites, an on-line monitoring structure layer formed by three-dimensional fabric of the glass fibers and an outer tank body layer formed by carbon fiber fabric composites and the glass fiber composites from inside to outside. According to the high-performance composite double-wall oil storage tank, the high-performance carbon fiber fabric is adopted, and therefore the material conductivity is improved, scattering of static electricity is promoted, the static electricity caused by friction between stored oil products and the inner wall is avoided, and potential safety hazards are eliminated; and the carbon fiber fabric and the glass fibers serve as the reinforcing materials, and therefore the ability of the tank to resist corrosion of the oil products is improved, the modulus and the strength of the tank are improved, and the material cost of the tank is effectively lowered.

Description

technical field [0001] The invention belongs to the technical field of composite material oil storage tanks, and in particular relates to a high-performance composite material double-wall oil storage tank and a preparation method thereof. Background technique [0002] With the gradual strengthening of environmental protection awareness and the gradual improvement of relevant laws and regulations, the underground oil storage tanks used in gas stations are being replaced to avoid the risk of secondary pollution of the surrounding soil due to poor corrosion resistance and short service life of existing metal storage tanks. The double-layer composite oil storage tank can effectively avoid the above problems. However, the existing oil storage cylinders made of composite materials have poor electrical conductivity and low modulus. Therefore, it is necessary to design and develop a double-wall oil storage tank with higher mechanical properties that can resist static electricity. ...
