Description

一种低温存储装置用锚固板 技术领域
本发明涉及一种低温存储装置用锚固板。
 背景技术
无论是天然气液化工厂，还是LNG接收终端，LNG储罐的投资均占有较高的比重，尤其是在LNG接收终端中，储罐的投资约占其总投资的30～40％，可见LNG储罐是整个LNG产业链中的一个非常重要组成部分。LNG储罐用来储存-162℃的超低温LNG(液化天然气)液体，为了使得储罐内液体处于超低温状态，储罐罐壁、罐底、罐顶均要安装布置保温材料。由于新型自支撑式LNG储罐复合结构内罐的外肋片结构，传统的内侧弹性毡、外侧膨胀珍珠岩罐壁保温方案存在材料松散、沉降变形、长期保温性能不稳定，寿命较低等方面的问题。现有的储罐主要为单容罐、双容罐以及全容罐：单容罐通常为立式平底园筒形储罐，由内罐和外罐组成。内罐材质为耐低温的不锈钢，用以储存低温的LNG，外罐一般由碳素钢制作,主要用于固定和保护维持内罐低温下工作的隔热层，但不能容纳LNG。当储罐出现事故，储存LNG的内罐泄漏时，LNG将损坏外罐，向更大区域漫延，造成更大的危害。为此单容罐必须设置围堰，按规范要求，工程设计中，单容罐需要较大的安全防护间距，占地面积较大。在储罐底部和侧壁都有接管，工程施工中易因施工质量欠缺留下气、液泄漏隐患。相对而言，泄漏可能性较高，强度较低，安全性能较差。由于单容罐的安全性较其他形式罐的安全性低，近年来在大型LNG生产厂已较少使用。双容罐的储罐的设计压力与单容罐相同（均较低），也需要设置返回气压缩机。双容罐的投资略高于单容罐，约为单容罐投资的110%，其施工周期也较单容罐略长。双容罐和全容罐比较，有差不多的投资和交付周期，但安全水平较低，现有储罐设计比较陈旧，也不被选用。另外全容罐虽然安全性较好、占地面积少，但是其结构较为复杂，施工工期较长，建设成本较高。常规的大型低温储罐是由金属内罐、混凝土外罐以及内外罐之间的保温层构成。在罐体底部，自下而上依次由混凝外罐金属底板、混凝土层、泡沫玻璃层、混凝土层、二次底板、预应力混凝土层、内罐金属底板构成；罐壁部分，自外而内，依次由混凝土外罐、外罐金属衬板、泡沫玻璃层、热角保护壁板、珍珠岩保温层、弹性毡保温层、金属内罐等结构构成，整个结构非常复杂，其安装施工过程繁杂且要求极高，每一步施工都必须在现场依次完成，从而导致现场施工质量要求高，质量控制难，施工周期长。在罐体的底部，金属内罐和外罐底板之间还有二次底板，罐壁部分，金属内罐和外罐之间有热角保护，金属内罐、二次底板、热角保护一般都是采用的是1-2厘米厚的低温钢，造价非常昂贵，施工焊接要求非常高。整个内罐和二次底板都是一个平整的整体，且热角保护与金属外罐和二次底板焊接成一个密封的整体。以一个16万立方的LNG储罐为例，其内罐直径80多米，开车运行时，会有近200℃的温度变化，不同结构层都会产生不同程度的收缩，内罐会有约25厘米的收缩，内罐是一个平整的整体，收缩会在不同层之间产生位移，相互之间的作用力非常大，一旦造成破坏，就会对保温效果产生影响，造成运行成本高，甚至会有安全问题。
 技术问题
为了克服已有大型低温储罐的结构复杂、安装施工过程繁杂且要求极高、成本较高的不足，本发明提供了一种简化结构、安装施工过程较为简便、成本较低的低温存储装置用锚固板。

所述内、外绝热层的厚度与对应的内、外保温结构层厚度一致，所述外绝热层的尺寸大于内绝热层，外保温结构层尺寸小于内保温结构层，从而使保温结构层与锚固板密缝拼接时形成错缝结构。
所述第二防护板表面呈内凹“十”形结构，所述的金属固定件呈”十”字形，所述金属固定件对应嵌入所述第二防护板的凹槽中并向内保温结构层延伸；所述金属固定件为耐低温金属材质，第二防护板为防火隔热材料，或局部填充固定有防火隔热材料，防火隔热材料位于与之接触的金属内罐焊接缝的正下方。
所述外绝热层由第四防护板和绝热材料组成，所述第四防护板为高强度板材。
所述外绝热层、渗漏防护结构和内绝热层通过通过胶粘剂黏结、刚性连接件贯穿紧固黏结或紧固与黏结组合进行。
进一步，所述外绝热层、渗漏防护结构和内绝热层通过刚性连接件贯穿紧固黏结，所述刚性连接件的空隙采用软质保温棒密缝填充。
