一种浮顶油罐的电荷释放装置
本技术涉及一种浮顶油罐组件,具体涉及一种浮顶油罐的电荷释放装置,属于浮顶油罐
技术介绍
浮顶油罐的火灾事故80%以上是雷击、静电导致的火灾;浮顶储罐浮顶与罐壁之间的静电荷和雷电流泄放主要方式有三种,一是通过浮梯连接油罐的罐壁和浮盘,二是在浮梯侧设置2根25mm2软铜复铰线,三是通过浮盘周围每隔3米安装的静电导触片与罐壁保持接触这三种方式;浮顶油罐浮顶在上下运行过程中内侧会沾上一层原油,将罐内壁的金属表面覆盖,使导触片与罐壁金属部位实际上不接触,或者有少量接触,存在较大的电阻,从而在相当程度上失去导电荷的作用,给油罐的安全运行到来隐患;根据《GB15599-2009石油与石油设施雷电安全规范》要求,浮顶金属油罐宜采用有效地、可靠的连接方式将浮顶与罐体沿罐周做均布的电气连接,连接点沿罐壁周长的间距不应大于30m;在美国API标准中,对于外浮顶储罐的静电接地,浮盘和罐壁之间需用适当数量的旁路导体作直接的电气连接;包括接点的每个导体两端的大电阻为0.03Ω,在浮盘所有升降状态时旁路导体必须保持小长度;旁路导体的平行间距不得大于30米储罐圆周,至少需要两条;现有的浮顶油罐其电荷释放装置容易出现连接不可靠,目前现有的此类装置结构较复杂,弹簧钢带卷盘和导电带卷盘分开设置,在长时间的运行过程中容易出现转动不灵活、卡阻、导电带脱离轨道的现象;再就是重量偏重,安装困难,在某些极端情况下可能会造成脱落,给油罐的安全运行造成隐患。
