技术领域
本申请属于贮存容器领域，具体而言，涉及一种双层储备罐及其漏点检测系统。
背景技术
目前，国内加油站使用的储油罐绝大多数采取地下埋藏的使用环境。罐体材质有钢罐、玻璃钢罐。结构上有单层罐、双层罐。双层罐又有内外罐均为钢罐(s/s)，内罐钢罐、外罐玻璃钢罐(s/f)和内外罐均为玻璃钢罐(f/f)三种。目前在使用的绝大多数仍然是以前投入使用的单层钢罐。由于在地下的埋藏环境，罐体的腐蚀损坏导致漏油，现已发生了很多起漏油事件破坏生态环境的案件。为了降低储油罐的漏油风险，国外已经改用双层结构的储油罐，国内也在近年来提出将单层罐逐步更换为双层罐。然而，双层罐在使用过程中，当内罐发生漏油时，所漏的油在内外罐之间的夹层空隙里，此时，只要外罐罐体上有一个漏油点，就会发生漏油污染环境的事故。并且寻找漏点工作量大，无法确认漏点的位置，给补漏增加了难度。
申请内容
本申请的目的包括提供一种双层储备罐，用做储油罐时能够有效地降低漏油事故的发生概率。
为了实现上述目的，本申请采用的技术方案如下：

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本申请实施例的组件可以以各种不同的配置来布置和设计。因此，以下对在附图中提供的本申请的实施例的详细描述并非旨在限制要求保护的本申请的范围，而是仅仅表示本申请的选定实施例。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。
在本申请的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“前”、“后”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，或者是该申请产品使用时惯常摆放的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
在本申请的描述中，还需要说明的是，除非另有明确的规定和限定，术语“设置”、“连接”应做广义理解，例如，可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
图1示出了本申请提供的双层储备罐的一种剖视图。如图1所示，该双层储备罐100包括内罐体和外罐体，内罐体用于储物如贮备油、气等，外罐体用作安全防护。其中，内罐体的侧壁为双层储备罐100的内壁101，外罐体的侧壁为双层储备罐100的外壁102。内壁101与外壁102之间具有夹层，所述夹层被分割为多个相互独立的密封单元103。每个密封单元103都具有独立的容纳空间。本实施例中，该双层储备罐100可以用作储液罐、储气罐等。
此外，双层储备罐100的内壁101被上述多个相互独立的密封单元103划分为多个第一区域，每个第一区域为一个所述密封单元103的第一侧壁103a。也就是说，上述多个相互独立的密封单元103的第一侧壁103a共同组成双层储备罐100的内壁101。
为了简化双层储备罐100的设计及制作工艺，在本申请的优选实施例中，双层储备罐100的外壁102可以直接作为上述多个独立密封单元103的第二侧壁103b。此时，双层储备罐100的外壁102被上述的多个相互独立的密封单元103划分为多个第二区域，每个第二区域为一个密封单元103的第二侧壁103b。
进一步的，每个密封单元103只具有第一侧壁103a或者只具有第二侧壁103b。即每个密封单元103都是只有第一侧壁103a，然后另外的部分通过其他的结构包裹阻隔，103b从一个面收缩为一个点或一条线；或每个密封单元103都是只有第二侧壁103b，然后另外的部分通过其他的结构包裹阻隔，103a从一个面收缩为一个点或一条线。这样的设定可以使整个密封单元只有在第一侧壁103a泄露、其他的包裹结构泄露、第二侧壁103b三者同时泄露的情况下，才会出现双层储备罐整体泄露。该设置降低了双层储备罐泄露的概率。
进一步的，每个所述密封单元同时具有第一侧壁103a和第二侧壁103b。该结构有利于将双层储备罐的夹层设计的更加结构工整，平衡性良好，便于使用，具有泄露时漏点检测方便的特点。
也就是说，在本申请的优选实施例中，内壁101与外壁102之间的夹层被隔挡部104隔挡为多个相互独立的密封单元103，且相邻两个密封单元103之间互不相通。内壁101被上述多个相互独立的密封单元103划分为多个第一区域，外壁102被上述多个相互独立的密封单元划分为多个第二区域。每个密封单元均包括第一侧壁103a和第二侧壁103b。每个密封单元103的第一侧壁103a为一个第一区域、第二侧壁103b为与该第一区域相对的第二区域。内壁位于夹层一侧被位于夹层的封闭单元隔挡分隔为多个第一侧壁；外壁位于夹层一侧被位于夹层的封闭单元隔挡分隔为多个第二侧壁；此时，上述多个相互独立的密封单元103的第一侧壁103a共同组成双层储备罐100的内壁101；上述多个相互独立的密封单元103的第二侧壁103b共同组成双层储备罐100的外壁102。此外，可以理解的是，除了第一侧壁103a和第二侧壁103b外，密封单元103还包括其他侧壁，这些其他侧壁的具体数量和结构由用于隔挡夹层以形成多个相互独立的密封单元103的隔挡部104决定。
例如，当上述双层储备罐100用作储油罐时，当储备罐的内壁101出现破损点即漏点时，内罐体中存储的油气将发生渗漏或泄漏，渗漏的油气将扩散到该漏点所在的第一区域对应的密封单元103内。此时，即使储备罐的外壁102存在漏点，只要该漏点不位于该密封单元103的第二侧壁103b，渗漏到该密封单元103内的油气就不会泄漏到外部环境中，减少了由于储油罐的泄漏造成的环境污染。也就是说，当有N个密封单元时，仅会在同一个密封单元的第一侧壁103a和第二侧壁103b同时有漏点，才 会发生泄漏事故。
可以理解的是，对于相同容量的双层储备罐100，在可实现的范围内，密封单元103的数量越多，双层储备罐100中的储备物如油、气等泄漏到环境中的概率越低，即双层储备罐100的可靠性越好。例如，双层储备罐100的夹层内设置有50个密封单元103，即使内壁101和外壁102均存在漏点时，发生泄漏的概率可低至1/2500。
需要说明的是，在本申请的其他实施方式中，多个独立密封单元103的侧壁也可以不包括外壁102。
本实施例中，内壁101与外壁102之间的夹层被隔挡部104隔挡为多个相互独立的密封单元103的实施方式有多种。每个密封单元103的结构由隔挡部104的形状以及储备罐的形状决定。具体的，隔挡部104可以根据储备罐的形状以及用户的需要设置。
作为一种实施方式，图2示出了本实施例提供的双层储备罐100的局部夹层中隔挡部104的一种结构示意图。如图2所示，双层储备罐100的夹层内设置有蜂窝状隔挡部1041，所述蜂窝状隔挡部1041用于将夹层划分为多个相互独立的密封单元103。也可以说，蜂窝状隔挡部1041与双层储备罐100的内壁101及外壁102共同构成上述多个相互独立的密封单元103。
作为另一种实施方式，图3示出了本实施例提供的另一种双层储备罐100的局部夹层中隔挡部104的另一种结构示意图。如图3所示，储备罐的夹层内设置有多个横向隔挡部1042和多个纵向隔挡部1043，多个横向隔挡部1042和多个纵向隔挡部1043用于将夹层划分为多个相互独立的密封单元103。也可以说，多个横向隔挡部1042、多个纵向隔挡部1043以及双层储备罐100的内壁101和外壁102共同构成上述多个相互独立的密封单元103。由于双层储备罐100的内壁101和外壁102可以是平面，也可以是曲面。
本实施例中，密封单元103的形状除了上述实施方式外，还可以是其他的形状。例如，密封单元103的形状可以近似于三棱柱，此时，密封单元103的截面形状可以是三角形，密封单元103的第一侧壁103a和第二侧壁103b分别作为该三棱柱的两个底面。同理，由于双层储备罐100的内壁101和外壁102可以是平面，也可以是曲面，因此，当双层储备罐100的内壁101或外壁102为曲面时，密封单元103的形状不是规则的三棱柱。
进一步的，三棱柱状的密封单元103的其中一个棱柱位于内壁，三棱柱状的密封单元的另两个棱柱位于外壁；或，三棱柱状的密封单元103的其中一个棱柱位于外壁，三棱柱状的密封单元的另两个棱柱位于内壁。
这样设计的原理在于：储存的物品只有在第一侧壁、三棱柱的另外两个侧壁中的一个、以及与三棱柱的另外两个侧壁中的一个相对应的第二侧壁三者同时发生泄露才会出现整体的泄露。降低整体泄露的概率。
作为变形，密封单元为四棱锥状。密封单元包括折叠设置或呈锯齿状设置在第一侧壁和第二侧壁之间的隔离板，每个锯齿均与相邻的第一侧壁或第二侧壁密闭连接，即相邻的两个锯齿与第一侧壁之间形成中空的三棱柱、相邻的两个锯齿与第二侧壁之间也形成中空的三棱柱。在中空的三棱柱内设有多个密封隔板，每个密封隔板均为三角形，两个三角形的顶角相连，即两个三角形相连的顶角为四棱锥的顶角，两个三角形、隔离板和第一侧壁之间形成四棱锥；两个三角形、隔离板和第二侧壁之间也形成四棱锥；位于隔离板和第一侧壁之间的多个四棱锥依次设置，共同形成三棱柱。位于隔离板和第二侧壁之间的多个四棱锥依次设置，共同形成三棱柱。为了方便理解，进一步的解释如下：将储备罐表面展开为一个平面，内壁和外壁之间的密封单元就如同三维空间内的层状结构。设X、Y平面与罐表面的展开平面对应，分别在X、Y两个方向在将2个对应的三角形展开在同一个Z空间里，构成的就是一个典型的类似菠萝表面的四棱锥空间结构。把这样的层状结构的密封单元覆盖在内壁与外壁之间，就是一种夹层空间的分隔模式。进一步的，夹层不是三角形的折纸形态，而是正弦波形的弯曲形态，也可以构成一种空间分隔形态。
为了简化工艺，内壁101被上述多个密封单元103所划分为的多个第一区域即所有密封单元103的第一侧壁103a的面积可以相等。当然，每个密封单元103的空间形状也可以相等。可以理解的是，由于储备罐的具体形状以及工艺限制，上述多个第一区域的面积难以做到完全相等，可能会存在细微的差异。例如，外罐的表面积大于内管的表面积，被分为相同数量的第一区域和第二区域，因此，上述“相等”应理解为近似相等。为了进一步实现泄漏信号的监测，以便于相关人员能及时补修，每个密封单元103内均设置有传感器105。需要说明的是，双层储备罐100内的每个密封单元103内均设置有传感器105，图2至图4中仅示意性地在其中一个密封单元103内示出了传感器105。传感器105用于感知和感测所在密封单元103内的泄漏信息，生成泄漏信号输出。例如，当双层储备罐100用作储油罐时，传感器105可以采用气敏传感器，气敏传感器可以检测到油、气的挥发从而生成相应的泄漏信号。通过采集并处理这些传感器105输出的泄漏信号即可以实现储备罐内壁101漏点的检测。
为了进一步提高漏点定位精度和降低罐体泄露污染的概率，上述多个密封单元103的空间形状和容积也可以根据需要做差异化设置。例如，各种不同的罐体发生化学腐蚀、物理破坏的高发位置分布具有各自的规律性，如罐底，油气分界面等位置，可以 按照漏点高发区域密封单元面积小，低发区域密封单元面积大的原则进行设置。在多个密封单元103的空间形状相似的情况下，对于双层储备罐上容易出现漏点的区域，第一区域的划分可以比不容易出现漏点的区域划分得小，即容易出现漏点的区域所划分的第一区域的面积比不宜出现漏点区域的第一区域的面积更小，此时，以该第一区域作为第一侧壁103a的密封单元103的容积也相应更小，能够有效地提高漏点的定位精度，同时，相同表面积上密封单元第一区域变小，对应于密封单元数量的增加，一个密封单元内外侧壁同时出现漏点的概率降低，双层储备罐泄露的概率降低，可靠性提高。
相比于现有的储油罐，本申请实施例提供的双层储备罐100通过在内罐体和外罐体之间的夹层内构筑多个相互独立的密封单元103，此时，双层储备罐100的内壁101被所述多个相互独立的密封单元103划分为多个第一区域，每个第一区域为一个密封单元103的第一侧壁103a，有效地降低了发生泄漏事故的概率，大大提高了双层储备罐100的可靠性。当内壁101和外壁102均存在漏点时，由于内壁101的漏点和外壁102的漏点不属于同一个密封单元103，所以不会导致泄漏事故发生，而此时油气泄露能够被安置在密封单元内的敏感传感器检测到，并且直接给出所对应的泄漏点位置。因此，当本申请实施例提供的双层储备罐100用作储油罐时，能够有效地降低漏油事故的发生概率，及时发现泄露并将泄漏点确定，减少了为寻找漏点耗费的时间成本和经济费用，缩短了维修过程，提高了储油罐的使用和服役时间。
本申请提供了一种双层储备罐的漏点检测系统。请参阅图4，该漏点检测系统10包括控制装置201以及上述第一实施例提供的双层储备罐100。双层储备罐100的每个密封单元103内均设置有传感器105，每个传感器105均与控制装置201电连接。
每个传感器105用于采集该传感器105所在的密封单元103内的泄漏信息，生成泄漏信号发送给控制装置201。本实施例中，具体传感器105的选取可以根据双层储备罐100具体储备物质的泄漏信息决定。例如，当双层储备罐100用作储油罐时，传感器105可以为对应油品的气敏传感器和油敏传感器，泄漏的油气通过漏点进入与该漏点对应的密封单元103时，气敏传感器可以检测密封单元103中油、气的浓度即泄漏信息，将该泄漏信息转换成电信号即泄漏信号发送给控制装置201。
控制装置201用于根据接收到的泄漏信号判断所述双层储备罐100的内壁101是否存在漏点，当所述双层储备罐100的内壁101存在漏点时，根据所述泄漏信号以及预先存储的位置对应表得到所述漏点的位置信息。具体的，控制装置201可以包括处理器和存储器。其中，处理器可以采用具有数据处理功能的芯片，例如，可以采用单片机、DSP、ARM或FPGA等。
其中，位置对应表中包括一一对应的传感器105的身份标识以及该传感器105所在的密封单元103的位置信息。例如，可以预先给每个传感器105均设置有编号，将该编号作为传感器105的身份标识。每个传感器105均对应于一个密封单元103，每个密封单元103的位置信息可以预先标定，然后将传感器105的身份标识与密封单元103的位置信息的对应关系以位置对应表的形式预先存储于控制装置201内。
此外，上述漏点检测系统10还可以包括报警装置202。报警装置202与控制装置201电连接。所述控制装置201还用于当所述双层储备罐100的内壁101存在漏点时，发送报警信息至所述报警装置202。所述报警装置202用于根据所述报警信息记录并发出警报。例如，报警装置202可以为声音报警器、光报警器或声光报警器等。
除了上述实施方式外，报警装置202也可以直接与双层储备罐100的每个密封单元103内设置的传感器105电连接，以发出漏点警报并警示漏点的位置。例如，报警装置202可以包括多个指示灯，每个指示灯与一个传感器105电连接，即每个指示灯对应于一个密封单元103，当某个指示灯被点亮时，则表示该密封单元103的第一侧壁103a存在漏点。当然，传感器105的信号一般较弱，报警装置202还可以包括放大电路，用于将传感器105输出的泄漏信号放大后再输出给指示灯。报警装置202的放大电路输出可以是按照检测到的油气信号强弱进行线性或非线性比例放大的信号，也可以是设置油气浓度阈值后的两值开关信号，可以是模拟信号，也可以是数字信号。
当然，为了使得相关人员能够方便获知漏点的位置信息并及时处理，本实施例提供的双层储备罐100的漏点检测系统10还可以包括显示装置，显示装置与控制装置201电连接。控制装置201得到漏点的位置信息后，发送给显示装置进行显示。
本申请实施例提供的双层储备罐100的漏点检测系统10，通过在上述双层储备罐100的每个密封单元103内设置的用于采集该密封单元103内的泄漏信息的传感器105，并通过控制装置201接收并处理每个传感器105发送的泄漏信号，能够较准确地监测罐体的泄漏状态以及漏点的位置，以便于相关人员能够及时采取补漏措施。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
工业实用性
