Problems solved by technology

However, it is rarely used in internal floating roof storage tanks, mainly because the size of the welded steel plate (1500mm) is larger than the size of the storage tank manhole (600mm). It is welded, and it cannot be replaced without destroying the storage tank, and maintenance is also difficult, so the application of the steel floating plate inside the floating roof storage tank is limited, and the steel floating plate needs to be heated during maintenance, which is easy cause an accident
[0011] The fully liquid-wetted steel floating plate mainly adopts single/double plate compartment floating plate welded by steel plate. The weight of the floating plate itself is relatively heavy, and there will be the following problems: when the floating plate shakes violently

Abstract

The invention provides a novel all-liquid floating disc and an implementation method thereof, the floating disc is good in sealing performance, can be suitable for an inner floating roof storage tankand an outer floating roof storage tank, and does not need to open a chamber of the tank body during construction so as to be convenient to install. The novel all-liquid floating disc comprises a floating plate main body immersed in and suspended in a liquid level, and is of a composite multi-layer structure, wherein the multi-layer structure comprises a bottom layer composite layer, a middle supporting layer, a top layer composite layer, and a surface paint layer; the bottom layer composite layer is made of an electrostatic conduction material, the glass fiber reinforced plastic and the high-strength resin are compounded on site in the storage tank to form electric conduction, corrosion resistance and a first-layer structure with the preset strength; the middle supporting layer is overlapped and covered above the bottom-layer composite layer, the middle supporting layer is a second-layer structure formed by a floating plate main body material on site in a storage tank; the top layercomposite layer and the top layer composite layer are overlapped and covered above the middle supporting layer, and is made of a conductive material, a glass fiber reinforced plastic and a high-strength resin in field in a storage tank, corrosion resistance and a third-layer structure with the preset strength; and the surface paint layer covers the upper surface of the top-layer composite layer.

Description

technical field [0001] The invention relates to the sealing technology of an oil storage tank, in particular to a novel fully liquid-contacted floating plate and a realization method thereof. Background technique [0002] Oil storage tank sealing technology, especially the floating plate sealing technology of floating roof oil storage tanks, is the key technology for oil storage. The existing floating disc overall sealing technology includes the following types: [0003] 1) Non-full liquid contact floating plate. [0004] The floating plate floats on the medium in the storage tank through multiple buoys, so there is a gas space between the floating plate and the medium, and the oil will volatilize into this space, and then pass through the space through the floating plate manhole or connecting parts. The components volatilize outward, causing leakage and volatilization, and the leakage area is the entire exposed oil surface, and the volatilization amount is large, so its s...
