本申请要求于2020年12月25日提交中国国家知识产权局的申请号为202011558450.4、名称为“一种采用液氢预冷的液氢储氢型加氢装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及加氢装置，尤其涉及一种采用液氢预冷的液氢储氢型加氢装置。
背景技术
随着全球温室效应问题的日益突出以及各国对氢能源开发利用的鼓励，越来越多的氢燃料电池汽车投入市场。加氢装置之于燃料电池汽车，犹如加油站之于传统燃油汽车、充电站之于纯电动汽车，是支撑燃料电池汽车产业发展必不可少的基石。
加氢站的核心是如何快速、安全的实现氢燃料加注。目前，不管是35MPa的铝内胆储氢气瓶还是70MPa的塑料内胆储氢气瓶，其耐压部分均靠气瓶外层缠绕的碳纤维层承担。然而不管是进口碳纤维还是国产碳纤维，最高使用温度均为85℃，而为了满足氢燃料电池车的商业化要求，需要保证车载高压储氢气瓶在5～10分钟内完成足量的氢气加注，但是高压氢气快速加注过程中会带来温升效应，因而高压氢气的加氢速度受到限制；此外充装完成时，如果车载高压储氢气瓶内部氢气温度过高，车载高压储氢气瓶虽能达到充装目标压力，但其加注质量也可能仍达不到额定重量。因此为了满足加氢站的商业化运营要求，提高高压氢气加注速率，需要对加氢机进行预冷。目前常规的加氢站均为加氢机配备相应的冷水机组来对加氢机进行预冷，但采用配备相应的冷水机组的方式的成本较高。

各第二高压储氢瓶47、各第二中压储氢瓶46的额定工作压力为90MPa，初始充装氢气压力为87.5±2.5MPa。为提升储氢瓶氢气取气率，采用二级加注工艺。二级加注高压蓄能器共包含九个储氢瓶，根据第二顺序控制盘的控制逻辑分成中压和高压两组并联连接，其中六个第二中压储氢瓶46并联构成第二中压储氢组，三个第二高压储氢瓶47并联构成第二高压储氢组。所有九个储氢瓶初始压力均为87.5±2.5MPa，加注方法可以为：
①二级加注高压蓄能器补气：当二级加注高压蓄能器的各第二中压储氢瓶46和各第二高压储氢瓶47的压力均达到87.5±2.5MPa时停止补气。
②中压储氢瓶组一级取气加注:二级加注高压蓄能器完成补气后，当首次进行70MPa高压氢气加注时，通过加氢站控制系统启动第二中压顺序控制阀组40从第二中压储氢瓶组取气给氢燃料电池车加氢至70MPa。完成首次加注后的第二中压储氢瓶组氢气压力将小于第二高压储氢瓶组内氢气压力。后续进行加注时仍先通过加氢站控制系统启动第二中压顺序控制阀组40从第二中压储氢瓶组取气加注，直至第二中压储氢瓶组与70MPa压差≤2MPa，无法通过一级取气加注实现70MPa加氢需求。
③第二中压储氢瓶组与第二高压储氢瓶组多级取气加注:当第二中压储氢瓶组与70MPa压差≤2MPa时，再次进行加注时先通过加氢站控制系统启动第二中压顺序控制阀组40从第二中压储氢瓶组取气加注，直至第二中压储氢瓶组与车载储氢气瓶的压差≤2MPa时关闭第二中压顺序控制阀组40，启动第二高压顺序控制阀组41从第二高压储氢瓶组取气加注，直至车载储氢气瓶压力达到70MPa。当第二中压储氢瓶组和第二高压储氢瓶组均与70MPa压差均≤2MPa时，再次进行二级加注高压蓄能器补气。
本方案通过设置第二中压储氢瓶组和第二高压储氢瓶组实现多级取气加注，从而最大限度提升第二中压储氢瓶组内氢气利用率，有效降低氢气使用成本，提高加氢站经济性。
