防海生物污染

防止船舶设备进水口及水冷却管道的生物污染。

船舶在海上航行时面临的主要问题之一是生物污染。 一直以来,贻贝、藤壶和其他类型的海洋生物都是导致船员航行效率降低的原因之一。 受到生物污染影响的不仅仅是船体,当生物污染附着船舶表面时,进水口和管道也可能被堵塞。 这将增加燃料消耗或降低需要使用水冷的设备性能。 需要使用水冷的设备包括发动机、发电机、液压油冷却器、泵、空调系统等。 某些情况可以使用防污漆和机械方式清除生物污染物,但在管道内部则需采用阻止海洋生物生长的其他方法。

生物污染处理方法的主要类型的包括:

电解制氯法

电解制氯法是一种通过产生氯气以生成用于防污的次氯酸钠的方法。 钛作为阴极材料,镀铂钛作为阳极。 氯同其他元素在阳极生成次氯酸钠:NaCl + H2O + 能量 > NaOCl + H2

该方法产生大量的氢气必须以安全的方式进行排放。 产生氯气的总量是电流的函数,因此必须保证流量实现冷却。 海水中10ppm的氯即可迅速杀死所有的海洋生物,而1ppm的氯即可实现防污效果。 该系统仅适用于海水环境。

电解系统

电解系统是防止生物污染最常用的系统之一。 电解系统是防止生物污染最常用的系统之一。 海水中的铜离子可以防止海洋生物在管道表面安家和繁殖。 但是在海洋中增加铜不利于生态环境,因此最好选择其他方法。

电解系统通常被称为:

ICAF——外加电流防海生物系统,或:
MGPS——海洋生长保护系统

化学加药

化学加药也是一种常用于阻止管网中的海洋生物生长的方法。 将防污化学药剂添加至海水箱。

超声波系统

超声波系统被认为是防止生物污染最有效的系统之一,可减少高达80%的海洋污染生长。 该系统通过使用超声波发生器,将高频电脉冲发送到位于海底阀箱中的传感器探头。 该系统的另一个优点是不使用有毒化学药剂。
