Embodiment 1

[0019] A cylindrical vacuum insulation board-insulated cryogenic liquid storage and transportation tank, which is composed of a C1.2 steel inner tank, a vacuum insulation board wrapped around the inner tank, a thin polyurethane foam layer and a stainless steel outer tank, wherein the inner , The thickness of the outer tank is 5mm, and the thickness of the vacuum insulation board wrapped around the inner tank is 40mm. Among them, polyetheramine modified epoxy resin is glued between the inner tank and the vacuum insulation board, and the thickness of the polyurethane foam filled between the vacuum insulation board and the outer tank is 30 mm. The tank body has excellent thermal insulation performance, has the advantages of safety, light weight, environmental protection, intelligence, large capacity, and long life. It can store cryogenic liquids, improve the use efficiency of liquefied natural gas, etc., and reduce the inflation frequency of ships.

Embodiment 2

[0021] A cryogenic liquid storage and transportation tank insulated by a spherical vacuum insulation panel, which is composed of a stainless steel inner tank, a vacuum insulation material layer wound on the surface of the inner tank, a thin layer of polyurethane foam and a carbon fiber reinforced resin matrix composite material shell, wherein, in the thickness The opening neck of the inner tank is sprayed with 2mm, and the outer surface of the inner tank is tightly covered with a bag-shaped packaging film material with thermoplastic polyimide. The composite film material encapsulates the wound inner tank as a whole and vacuumizes it, and obtains a vacuum insulation material layer with a thickness of 35mm outside the inner tank. On the outside of the vacuum insulation layer is a polyurethane foam layer with a thickness of 20mm and a carbon fiber reinforced epoxy resin matrix composite shell with a thickness of 5mm. The tank body has excellent thermal insulation performance, has...

Embodiment 3

[0023] A cryogenic liquid storage and transportation tank with frustum-shaped vacuum insulation panels, which is composed of a C1.2 steel inner tank, a vacuum insulation material layer wound on the surface of the inner tank, a thin polyurethane foam layer and a glass fiber reinforced resin-based composite material shell , wherein the thickness of the inner tank is 4mm, and a Teflon annular plastic layer with a thickness of 20mm is sprayed on the opening neck of the inner tank, and thermoplastic polyimide is tightly laminated and wound with 40 layers of glass wool core material and aluminum foil below the neck, Vacuumize the bag-shaped composite film material and heat seal with the annular Teflon layer to obtain a vacuum insulation material layer with a thickness of 30mm outside the inner tank. Outside the vacuum insulation layer is a polyurethane foam layer with a thickness of 15mm and a glass fiber reinforced epoxy resin based composite shell with a thickness of 7mm. The tank...

Abstract

A cryogenic liquid storage and transportation tank adopts a double-wall interlayer structure, which is characterized in that the tank body is formed by compound connection of multi-layer materials, and the order from the inside to the outside is an inner tank, a middle composite cold-preservation layer and an outer tank. The thickness of the inner tank is 2-10mm, and the material is low alloy steel. The thickness of the outer tank is 2-15mm, and the material is stainless steel, aluminum alloy or carbon fiber reinforced resin-based composite material. The middle composite cold insulation layer is composed of a vacuum insulation material layer and a thin polyurethane foam layer. The vacuum insulation material layer is an ultra-thin glass wool core material packaged with a film material or a vacuum layer in which an ultra-thin glass wool core material and aluminum foil are alternately laminated, and the bag-shaped packaging film material is used for annular vacuum packaging. The storage and transportation tank is light in weight, large in capacity, non-polluting, and has a wide range of applications; compared with traditional storage tanks, it has the advantages of safety, light weight, environmental protection, intelligence, cryogenic cooling, large capacity, and long life, and can store liquefied natural gas Etc., improve service efficiency, reduce the inflation frequency of steamer.

Description

technical field [0001] The invention relates to a liquid storage and transportation tank, in particular to a cryogenic liquid storage and transportation tank insulated by a vacuum insulation board. Background technique [0002] Ships such as freighters and passenger ships release a large amount of PM2.5 due to the burning of diesel. PM2.5 refers to particulate matter in the ambient air with an aerodynamic equivalent diameter of 2.5 microns or less, also known as particulate matter that can enter the lungs. After being inhaled, it will directly enter the human body. Bronchus, which interferes with gas exchange in the lungs, contributing to diseases including asthma, bronchitis and cardiovascular disease. The main component of natural gas is methane, the molecular formula is CH 4 , the combustion is complete, and the combustion product is only a small amount of CO 2 and H 2 O, is a clean energy with low cost, high heat conversion efficiency and abundant reserves. Because t...
