氢气直接排放大气有那些要求? 比如排放量 高度?
Reply #22020-04-13
本帖最后由 zhanyl628 于 2020-4-13 09:29 编辑 《氢气站设计规范》有如下规定,供参考!12.0.9 氢气放空管,应设阻火器。阻火器应设在管口处。放空管的设置,应符合下列规定:1 应引至室外,放空管管口应高出屋脊1m;2 应有防雨雪侵入和杂物堵塞的措施;3 压力大于0.1 MPa时,阻火器后的管材,应采用不锈钢管。

对 这个明白 就是排放的量有没有要求 或者上限呢

应该是有要求的,比如气速太快静电接地不良的话可能起火。 高度应有避雷装置。 流量过大周围扩散后仍处于爆炸范围的话应加高

氢气非污染物,但为能源。故无所谓的排放限值要求。对空排放,从安全角度考虑,排放速率取决于温度、压力、管内介质及管道材质等因素,在压力不太高的情况下(如0.1~3.0MPa)碳钢取15m/s,不锈钢取25m/s应在安全范围内。

短期试验 PSA不想开 尾部富含氢气气体直接拍大气 但是量有点大 流速没什么问题 考虑会不会空气聚集性风险 不知道有没有这样的要求

必须有阻火器,应该还得有氮气或者蒸汽的应急吹扫

氢气轻气,不会有空气聚集性风险!

室验装置 工期短 回收性价比低
