How Oil Water Separator Works ?
Summary
TLDRShips generate waste oil from various sources, which is managed by segregating it into sludge and bilge. Dedicated tanks store this mixture, separating oil and water through heating and centrifugal separators. Onboard Waste Oil Separator (OWS) equipment filters bilge water through multiple stages, ensuring oil content is below 15 PPM for legal discharge. An Oil Content Monitor (OCM) controls the process, directing excess oil to sludge tanks for proper disposal and releasing clean water, protecting the ecosystem.
Takeaways
- 🚢 Ships produce a significant amount of waste oil from various sources, including engine lubrication and fuel consumption.
- 🚫 It is illegal for ships to discharge waste oil overboard, which can result in fines and imprisonment.
- 📦 Waste oil is managed by segregating it into sludge and bilge, stored in dedicated tanks on the ship.
- 🔥 Heating arrangements are used to control the viscosity of oil and separate water from it.
- 💧 Bilge and sludge tanks are designed to handle different oil-water mixtures, with bilge having less oil and sludge having more.
- 🛠️ Machinery leakage is directed to either bilge or sludge tanks, depending on the oil content.
- 🌀 The centrifugal separator is used to further treat fuel, separating additional impurities as sludge and water.
- 🚰 Onboard Wastewater Separation (OWS) equipment filters bilge water through multiple stages of filtration based on densities.
- 🛑 The first filter unit in the OWS uses catch plates and a coalescer to separate oil from the mixture.
- 🔍 The second filter unit ensures the output has less than 15 PPM of oil to meet legal discharge criteria.
- 📊 The oil content monitor (OCM) continuously checks the PPM of oil, and if high, triggers an alarm and directs the mixture to the sludge tank.
Q & A
船只如何处理产生的废油?
-船只通过将废油分离成油渣和舱底水,并在专门的油渣和舱底水储存罐中存放来处理废油。舱底水和油渣是油和水的混合物,不同之处在于舱底水中油的含量较少,而油渣中油的含量较多。
为什么船只不能将废油直接排放到海里?
-直接将废油排放到海里是违法的,可能会导致高额罚款和船员监禁。因此,船只必须合法处理废油,以保护海洋环境。
船上的油水分离器(OWS)是如何工作的?
-油水分离器通过不同的过滤阶段来分离油和水,这些阶段基于它们的密度差异进行设计。OWS由三个部分组成:第一级过滤单元、第二级过滤单元和油含量监测与控制单元。第一级过滤单元通过捕集板和油收集室使油因密度低于水而上升;第二级过滤单元进一步去除油,确保输出少于15ppm以满足法定排放标准;第三级单元包括油含量监测器,如果油含量过高则发出警报,并将油水混合物排入油渣罐中。
船只如何确保废油得到妥善处理?
-船只通过将废油收集并存储在专用的油渣和舱底水储存罐中,然后通过油水分离器进行处理,分离出的油被收集并适当处置,而清洁的水则被释放到环境中。这个过程确保了船只的废油得到适当管理,不会对周围生态系统造成伤害。
船上的废油储存罐有什么特别的设计吗?
-船上的废油储存罐配有加热装置以保持油的粘度在一定限度内,并分离出水。这些罐可以从底部排出沉积的重水,并将其排入舱底水罐。
船只如何处理机械泄漏产生的废油?
-机械泄漏产生的废油根据泄漏混合物中所含油量的不同,被送往舱底水或油渣罐。
船只的废油管理计划包括哪些内容?
-根据MARPOL Annex V的规定,100总吨位及以上的船舶、载客15人或以上的船舶以及每个固定或浮动平台都必须携带垃圾管理计划,其中包括最小化、收集、储存、处理和处置垃圾的书面程序。
船只如何处理食品废物和污水?
-船只必须遵守严格的环境保护规定,特别是针对极地水域的条件,例如北极水域和南极区域。食品废物和污水通常需要在船上进行处理,以减少对海洋环境的污染。
船只的废油记录簿有什么作用?
-根据MARPOL Annex V的规定,所有100总吨位及以上的船舶以及载客15人或以上的船舶必须配备废油记录簿,记录所有处置和焚烧操作。这有助于执行和加强废油管理规定的遵守。
船只的废油是否可以回收利用?
-是的,废油可以回收利用。例如,废食用油可以通过加工转化为生物燃料,这不仅解决了食品安全、污染和能源安全问题,而且还提供了一种三赢的替代方案。
