Abstract
本发明涉及一种用于存储气态介质,例如氢气或天然气的设备(1),包括存储管路(20),至少一个罐容器(6)连接到所述存储管路(20)上。此外,在所述存储管路(20)中布置有至少一个通风装置(15),用于引入气态介质、尤其是空气。
Description
技术领域
本发明涉及一种用于存储气态介质,例如氢气或天然气的设备。在使用氢气时,该设备应用于具有燃料电池驱动器的车辆或具有氢燃烧器作为驱动器的车辆。
背景技术
在移动应用中,压力气体通常储存在单个压力气体罐或多个压力气体容器或压力气体瓶中。为安全起见,必须在任何时候确保罐或瓶的密封性。因此,使用安全电磁阀用于安全地关闭压力气体容器,该安全电磁阀在无电流状态下关闭,使得即使在故障情况下也可靠地避免气体逸出。
由公开文献DE 10 2017 004 451 A1已知一种用于压力气体的存储装置,该存储装置具有多个压力气体容器,这些压力气体容器分别通过罐阀和管路元件连接到一个共同的收集体积上。收集体积,也可以称为“轨”减少了管道费事。
存储装置构造得越封闭,则例如会在车辆底部形成空腔,在该空腔中可能形成临界的氢浓度。
发明内容
相比之下,根据本发明的设备的优点在于,提供一种结构简单且节约成本的用于存储气态介质的设备,该设备具有主动的通风装置,从而使安全相关的可点燃的气体浓度最小化。
为此,用于存储气态介质,例如氢气或天然气的设备具有存储管路,至少一个罐容器连接到存储管路上。此外,至少一个用于引入气态介质、尤其空气的通风装置布置在存储管路中。
因此,可以以结构简单的方式防止,在设备上可能形成安全临界的氢浓度,这导致设备损坏或甚至爆裂。
在第一个有利的扩展方案中,通风装置包括阶梯形入口区域、扩散区域和锥形出口区域。有利地,扩散区域通过通道至少间接地与至少一个罐容器连接。因此,可以特别优选地实施气态介质的流动。尤其,气态介质的引导基于文丘里喷嘴的原理实现。
在本发明的另一构型中有利地设置,通风装置为了引入气态介质、尤其是空气而包括循环鼓风机。有利地,气态介质、尤其是空气能够通过循环鼓风机从周围环境吸入并且能够借助通风装置流过用于储存气态介质的装置。
所描述的设备优选地适用于燃料电池系统,以存储运行燃料电池的氢气。有利地,具有通风装置的根据本发明的设备具有以下优点:当吸入空气的一部分例如为了燃料电池中的冷燃烧而通过所述设备被引导,则不需要用于另外的风扇和附件、用于设备的另一主动通风装置的额外的能量或成本。
此外,所描述的用于存储氢气以运行燃料电池的设备也有利地适用于燃料电池运行的车辆。
此外,所描述的用于存储氢气的设备也有利地适用于氢动力车辆,即在具有氢燃烧器作为驱动器的车辆中。
附图说明
在附图中示出根据本发明的用于存储气态介质、尤其是氢气或天然气的设备的实施例。附图示出了:
图1:根据本发明的设备的实施例的简化示意图,该设备具有用于引入气体介质的通风装置,
图2:图1的用于引入气态介质的通风装置的纵截面。
具体实施方式
图1以简化示意图示出根据本发明的用于存储气态介质,例如氢气或天然气的设备1的实施例。
设备1具有存储管路20和多个具有纵轴线30的罐容器6。存储管路20具有存储管路壳体2,在该存储管路壳体中可以布置有另外的结构部件72,例如阀。
存储管路20与消耗装置系统70,例如燃料电池系统的阳极区域流体连接。存储在罐容器6中的气态介质,例如氢气通过存储管路20分配到相应的消耗装置系统70中并且给消耗装置系统提供气态介质。
在对罐容器6充注的情况下,存储管路20与外部加注站71连接并且因此提供必要的气态介质。
存储管路20和罐容器6形成设备1的流体密封的连接装置90,因为它们例如相互拧紧并且因此彼此固定。
此外,用于引入气态介质、尤其是空气的通风装置15布置在存储管路20中。在另外的的实施方式中,多个通风装置15在存储管路20中布置在罐容器6上。
此外,在每个罐容器6上布置有截止阀(在此未示出),以便将来自罐容器6的气态介质流通过存储管路20朝消耗装置系统70的方向引导。此外,截止阀可以在紧急情况下截止各罐容器6,从而使气态介质保险在罐容器6中并且不能向外流出。
除截止阀外,在用于存储气态介质的设备1中还存在能够热激活的阀,以便确保在加热作用的情况下,例如通过火灾触发时安全地导出气态介质。
图2以纵截面示出图1的通风装置15。通风装置15包括阶梯状入口区域12、扩散区域16和锥形出口区域13。在此,扩散区域16通过通道14至少间接地与罐容器6连接。即通道14通到存储管路20中,该存储管路又通到罐容器6的颈部区域中。在另外的实施方式中,每个罐容器6在颈部区域中具有通风装置15,其中,通道14直接通到罐容器6的颈部区域中。为了最优的交换效果,气态介质通过通风装置15的引导在此基于文丘里喷嘴的原理。
根据设备1中的空气控制方案和所需的空气交换,流速、横截面可以如此适配并且设备如此与相应的临界位置,例如空腔连接,使得始终低于临界气体浓度。
此外,通风装置15还包括循环鼓风机11,通过该循环鼓风机11从周围环境中吸入气态介质,并且借助通风装置15,使气态介质流过用于存储气态介质的设备1以及消耗装置系统70。
因此,设备1例如可以借助通风装置15用来自作为消耗装置系统70的燃料电池系统的周围环境的新鲜空气冲洗。此外,通过用于为燃料电池系统提供氢的设备1的接头,也能够使新鲜空气充满燃料电池系统。在此,除在燃料电池系统中已经存在的气流机械以外,空气还可以被供应给燃料电池系统的燃料电池的阴极入口区域,并且因此可以作为反正需要的吸入空气的一部分,用于燃料电池中的冷燃烧。
除了燃料电池运行的车辆外,用于储存气体介质的设备1例如也可以用于在具有氢燃烧器作为驱动器的车辆中的氢存储。
用于储存气态介质的设备1也可以在基于天然气的车辆中用于储存天然气。
