Problems solved by technology

The disadvantage is that it is very difficult to manufacture a super-large prestressed reinforced concrete cylindrical tank, even if it is made by welding three to four arc sections; It is very difficult to bear the force
At present, the domestic design and production technology is still in the initial stage of trial production
At the same time, the above-mentioned storage tanks are all non-pressure storage tanks and cannot bear any internal pressure, which requires strict monitoring and control of the refrigeration system, so the energy consumption of the refrigeration system is very high
With the increase of market demand, LNG storage tanks are getting bigger and bigger, and the internal requirements must have a certain pressure, so the above design and production are difficult to meet the requirements

Embodiment Construction

[0012] exist figure 1 Among them, the material layer (1) includes a layer on the bottom surface, which is an inner coating or an inner coating layer, the inner coating is leak-proof, anti-freeze cracking, and anti-corrosion paint, and the inner coating layer is low-temperature nickel steel, stainless steel, ceramics or low-temperature resistant The plastic board can also be composed of an inner coating and an inner layer. This stress-bearing layer is a rectangular or rectangular LNG tank of prestressed reinforced concrete in the inner layer, and it is best to adopt small pieces of ceramics as the material layer (1). The prestressed reinforced concrete layer (2) of the force-bearing layer can include a bottom surface and vertical four walls that are all straight plates, and the overall fabrication and processing are very easy. The prestressed reinforced concrete beam frame (4) can be manufactured together with the prestressed reinforced concrete layer (2). The prestressed rei...

Abstract

Design and manufacturing of an ultra-large rectangular or oblong-shaped LNG storage tank are characterized in that the cross section of a tank body of the LNG storage tank is rectangular or in the shape of an oblong, a stressed layer of the tank wall is made of pre-stressed reinforced concrete in a blocked mode or in an integrated mode, longitudinal, transverse and vertical three-direction pre-stressed reinforced concrete beam frames are arranged in the wall of the tank, a top cover of the tank is in the shape of a one-way arc face or a flat top or a slope, and the top cover of the tank is supported on stand columns. A heat-preserving layer is arranged on an outer layer or an inner layer, or both the inner layer and the outer layer are respectively provided with a heat-preserving layer. A material containing layer is an inner coating layer or an inner adhering layer, or the material containing layer is composed of both the inner coating layer and the inner adhering layer, the inner coating layer is made of anti-leakage, anti-frost crack and anti-corrosion coating, the inner adhering layer is made of low-temperature nickel steel, stainless steel, ceramic or low-temperature-resistant plastic boards, and therefore the high-difficulty design and the high-difficulty manufacturing of the ultra-large LNG tank are converted into design and manufacturing of a large conventional pre-stressed reinforced concrete building, successful and rich experience is achieved in both the design and the manufacturing of the large conventional pre-stressed reinforced concrete building by people, people only need to pay attention to selection and utilization of ultra-low-temperature materials, and the design can guarantee that pressure in a 200000m<3>-400000m<3> LNG storage tank can reach 3mpa. The cost for the design and the manufacturing is several times smaller than that of an existing LNG storage tank, and stress, stability, anti-disaster performance and borne inner pressure of the designed and manufactured LNG storage tank are several times higher than those of the LNG storage tank in existing design.

Description

Technical field [0001] The patent of the invention relates to the design and manufacture of a rectangular or rectangular super-large LNG storage tank, which belongs to the field of petrochemical low-temperature liquefied natural gas LNG storage tanks, and is widely applicable to the storage of chemical low-temperature liquids. Background technique [0002] At present, it is known that large-scale liquefied natural gas storage tanks (LNG) in the petrochemical industry, no matter single-capacity, double-capacity or full-capacity, are usually cylindrical, with a spherical top cover, an inner wall lined with an insulating layer, and the innermost layer is Metal container, the outermost layer is a prestressed reinforced concrete tank. The advantages of this structure are: it is made at room temperature, and when working at -165°C, it can ensure that the steel bar is under tension and the concrete is evenly compressed at the same time, so that the concrete will not shrink and crac...
