  • 本站编辑:杭州萧山升达防腐设备厂发布日期:2019.09.10

 卧式油罐是储存油品的容器,它是石油库的主要设备。适用于储存工业或民用设施中常用的燃料油及各种石油化工原料。储油罐按材质可分金属油罐和非金属油罐;按所处位置可分地下油罐、半地下油罐和地上油罐;按安装形式可分立式、卧式;按形状可分圆柱形、方箱形和球形。

 
Horizontal tank is the container for storing oil products, and it is the main equipment of oil depot. It is suitable for storing fuel oil and various petrochemical raw materials commonly used in industry or civil facilities. Oil storage tanks can be divided into metal tanks and non-metal tanks according to their materials, underground tanks, semi-underground tanks and above-ground tanks according to their s, separate and horizontal tanks according to their installation forms, and cylindrical, square and spherical tanks according to their shapes.
 
 
 
卧式储油罐存放比较容易。压力:常压;温度:-25℃~180℃;介质:燃料油(石油化工原料等)
 
Horizontal tanks are easier to store. Pressure: atmospheric pressure; temperature: - 25 ~180 C; medium: fuel oil (petrochemical raw materials, etc.)
 
 
 
卧式储油罐的构造要严格。
 
Horizontal tanks should be constructed strictly.
 
 
 
焊接,严格按图纸、方案和焊接工艺指导书施工;充分发挥质保体系的作用,确保质保体系的正常运行;严禁使用无产品合格证和材质证明书的焊接材料。当对材料有怀疑时,应进行化验,以确定是否可用。第二尤其要防腐储油罐的外表面防腐设计应符合国家现行标准《钢质管道及储罐腐蚀控制工程设计规范》的有关规定,并应采用不低于加强级的防腐绝缘保护层;储油罐的内壁防腐措施应根据罐内贮存介质确定。
 
Welding shall be carried out strictly in accordance with drawings, schemes and welding process instructions; the role of the quality assurance system shall be brought into full play to ensure the normal operation of the quality assurance system; and the use of welding materials without product qualification certificates and material certificates shall be strictly prohibited. When there is doubt about the material, a test should be carried out to determine whether it is available. Secondly, the external surface anticorrosion design of anti-corrosive oil storage tanks should conform to the relevant provisions of the current national standard "Code for Design of Corrosion Control Engineering for Steel Pipelines and Storage Tanks", and should adopt an anti-corrosive and insulating protective layer lower than the reinforced level; the anti-corrosive measures for the inner wall of oil storage tanks should be determined according to the storage medium in tanks.
 
 
 
按用途分
 
By use
 
 
 
a、地上油罐地上油罐指的是油罐基础高于或等于相邻区域最低标高的油罐,或油罐埋没深度小于本身高度一半的油罐。地上油罐是目前炼油企业常见的一类油罐,它易于建造,便于管理和维修,但蒸发损耗大,着火危险性较大。
 
A. The above-ground tank refers to a tank whose foundation is higher than or equal to the lowest elevation in the adjacent area, or a tank whose buried depth is less than half of its own height. Above-ground tank is a common type of oil tank in oil refining enterprises. It is easy to build, easy to manage and maintain, but it has high evaporation loss and high fire risk.
 
 
 
b、埋地油罐地下油罐指的是罐内最高油面液位低于相邻区域的最低标高0.2m,且罐顶上覆土厚度不小于0.5m的油罐。这类油罐损耗低,着火的危险性小。
 
B. Underground oil tank of buried oil tank refers to oil tank whose highest oil level is lower than the lowest elevation of 0.2m in adjacent area, and whose top soil thickness is not less than 0.5m. This kind of tank has low loss and low risk of fire.
 
 
 
c、半地下油罐半地下油罐指的是油罐埋没深度超过罐高的一半,油罐内最高油面液位比相邻区域最低标高不高出2m的油罐。
 
C. Semi-underground oil tank and semi-underground oil tank refer to the oil tank whose buried depth is more than half of the height of the tank. The highest oil level in the tank is not higher than the lowest elevation in the adjacent area by 2 m.
 
 
 
常见的金属油罐形状,一般是立式圆柱形、卧式圆柱形、球形等几种。立式圆柱形油罐根据顶的结构又可分为桁架顶罐、无力矩顶罐、梁柱式顶罐、拱顶式罐、套顶罐和浮顶罐等,其中最常用的是拱顶罐和浮顶罐。拱顶罐结构比较简单,常用来储存原料油、成品油和芳烃产品。浮顶罐又分内浮顶罐和外浮顶罐两种,罐内有钢浮顶浮在油面上,随着油面升降。浮顶不仅降低了油品的消耗,而且减少了发生火灾的危险性和对大气的污染。
 
Common shapes of metal tanks are usually vertical, horizontal and spherical. The vertical cylindrical tank can be divided into truss roof tank, moment-free roof tank, beam-column roof tank, vault roof tank, sleeve roof tank and floating roof tank according to the structure of the roof. The most commonly used are vault roof tank and floating roof tank. The structure of vault tank is relatively simple, and it is often used to store raw oil, refined oil and aromatic hydrocarbon products. Floating roof tank is divided into inner floating roof tank and outer floating roof tank. There are steel floating roof floating on the oil surface in the tank, which rises and falls with the oil surface. Floating roof not only reduces oil consumption, but also reduces the risk of fire and air pollution.
 
 
 
尤其是内浮顶罐,蒸发损耗较小,可以减少空气对油品的氧化,保证储存油品的质量,对消防比较有利。目前内浮顶罐在国内外被广泛用于储存易挥发的轻质油品,是一种被应用的储油罐。
 
Especially for the inner floating roof tank, the evaporation loss is small, which can reduce the oxidation of air to oil, ensure the quality of stored oil, and is more favorable for fire protection. At present, the inner floating roof tank is widely used to store volatile light oil at home and abroad, which is a kind of oil storage tank.
