Description

一种抗震LNG气瓶
技术领域
本发明涉及一种LNG气瓶，尤其是涉及一种抗震LNG气瓶。
背景技术
LNG（Liquefied Natural Gas），即液化天然气的英文缩写。天然气是在气田中自然开采出来的可燃气体，主要由甲烷构成。LNG是通过在常压下气态的天然气冷却至-162℃，使之凝结成液体。天然气液化后可以大大节约储运空间，而且具有热值大、性能高等特点。
LNG汽车是液化天然气汽车的简称。LNG汽车是以低温液态天然气为燃料的新一代天然气汽车，其突出优点是LNG能量密度大(约为CNG的3倍)，汽车续驶里程长，可达400km以上，相对汽车使用柴油、汽油具有显著的经济效益。
LNG汽车和加气站技术的关键在于LNG的储存和运输，因为-162℃的温度对LNG设备有一些特殊要求，因此其技术难度较CNG和LPG都大。但从一些发达国家的应用来看，LNG汽车和加气站技术是完全成熟的。日前，国内LNG加气站的主要设备如低温常压储罐和空温式气化器等，国内生产厂家已掌握了有关核心技术，可大批量生产。
现有技术的LNG气瓶多为钢结构固定，并且内胆与外壳之间也是由钢构件固定连接，钢构件固定连接虽然牢固，但是其抗震性能差，汽车在运动过程中是不断处于震动状态，对于抗震性能要求很高，不然就会降低LNG气瓶的使用寿命，因此一种具有良好抗震性能的LNG气瓶是非常必要的，同时钢构件的LNG气瓶其导热性能强，不利于LNG的储存。
发明内容
本发明所要解决的问题是，针对上述现有技术中的缺点，提出改进方案或者替换方案，尤其是一种提高LNG气瓶的抗震效果和降低LNG气瓶内胆和外壳之间的热能传到的改进或者替换方案。
为解决上述问题，本发明采用的方案如下：一种抗震LNG气瓶，其特征在于，所述抗震LNG气瓶包括内胆和外壳；所述内胆设置在外壳内；所述内胆和外壳之间形成隔热空腔；所述隔热空腔内为真空状态；所述内胆与外壳之间设有减震支撑柱；所述内胆和外壳上设有与减震支撑柱相匹配的凹槽；所述减震支撑柱设置在凹槽内。
进一步，根据上述设计方案所述一种抗震LNG气瓶，其特征在于，所述减震支撑柱均为橡胶注塑结构。
进一步，根据上述设计方案所述一种抗震LNG气瓶，其特征在于，所述内胆内部设有液位感应器。
进一步，根据上述设计方案所述一种抗震LNG气瓶，其特征在于，所述减震支撑柱为蜂巢结构。
本发明的技术效果如下：本设计通过将LNG气瓶的内胆和外壳之间真空设置，同时将现有技术的LNG气瓶的内胆和外壳通过钢构件连接改为减震支撑柱，并且减震支撑柱均是由橡胶注塑而成，不仅提高了LNG气瓶的抗震性能，同时也增强了LNG气瓶的内胆与外壳之间的隔热性能，同时，本申请的LNG气瓶的减震支撑柱设置在凹槽内，防止减震支撑柱因震动而移位。
附图说明
图1为抗震LNG气瓶结构示意图。
图2为蜂巢结构的减震支撑柱。
其中，1为外壳、2为内胆、3为减震支撑柱、4为液位感应器、5为凹槽。
