  • 卧式储油罐应该如何清洁?
  • 本站编辑:杭州萧山升达防腐设备厂发布日期:2020.01.07

 油罐需要专业的而工作人员进行定期的清洁,这样能在很大的程度上保证酒罐内部的洁净,也能够保证新的油品不收污染,但是在清洁的过程中应该注意什么呢?就由卧式储油罐加工厂家来告诉我们吧!

1、原油罐清洗
 
储油罐机械清洗系统是用临时敷设的管道将机械清洗设备与清洗油罐、清洗油供给油罐及接收油罐连接在一起,先将被清洗油罐底部具有流动性的原油移送至其它油罐中,然后用设置在清洗油罐单盘上的清洗机,喷射清洗热油击碎溶解淤渣及凝油,并将其移送至接收油罐中,最后用温水进行循环清洗,同时进行油水分离,最终清除罐内所有污油,以达到罐内动火条件。
 
2、成品油油罐清洗
 
清洗装置集成清洗回收、精密过滤、施工过程中气体检测、罐内注入惰性气体(氮气)所需的膜制氮机几项功能于一体。设备整体成橇,方便运输施工方便。
 
油罐清洗是一项比较危险的罐内作业,这是由于油蒸汽不仅易燃、易爆且有毒。因此,洗罐时必须严格遵守下列安全规定:
 
1、打开人孔,分层检查罐底油料质量,确定存油排除及处理方案;
 
2、进罐人员必须穿戴工作服、工作鞋、工作手套、戴防毒面具。还要带上信号绳和保险带,罐外专人监护,进罐时间不宜太长,一般为15至20min为宜,轮班作业。另外,现场应有医护人员值班;
 
3、清洗残油污水应用扫帚或木制工具,严禁用铁器和钢制工具;
 
4、须采用有效的通风;
 
5、蒸汽法——开始应封闭罐内所有孔盖,待温度达到60至70℃时,再打开盖继续蒸洗,使罐内残油完全溶解为止。
 
油罐的洁净影响到油品质量,未经处理的油罐,将会出现管道堵塞、结垢、腐蚀,油品低质,比如油罐因腐蚀泄漏、原油污染等。石油储罐使用寿命一般较长,使用一段时间后,原油中的杂质将会沉积在罐底和罐壁上面,导致油罐有效容量减少,影响储罐油罐的效率。油罐的长期使用,会产生腐蚀和泄露,如果对油罐检查轻忽,将会给我们带来严重的安全隐患,威胁着周边环境和油罐区的安全。
The oil tank needs to be cleaned regularly by professional staff, so as to ensure the cleanness of the inner part of the wine tank to a large extent, as well as the non pollution of new oil products. But what should be paid attention to in the process of cleaning? Let's know from the manufacturer of horizontal oil storage tank!
 
1. Oil tank cleaning
 
 
 
The mechanical cleaning system of oil storage tank is to connect the mechanical cleaning equipment with the cleaning oil tank, cleaning oil supply oil tank and receiving oil tank with the temporarily laid pipeline. Firstly, the crude oil with liquidity at the bottom of the cleaned oil tank is transferred to other oil tanks, and then the cleaning machine set on the single plate of the cleaning oil tank is used to spray the cleaning hot oil to break up the dissolved sludge and condensate, and transfer it to the joint In the oil collection tank, warm water is used for circulating cleaning, oil-water separation is carried out at the same time, and all the dirty oil in the tank is finally removed to achieve the hot work conditions in the tank.
 
 
 
2. Cleaning of product oil tank
 
 
 
The cleaning device integrates several functions, such as cleaning recovery, precision filtration, gas detection during construction, and membrane nitrogen generator required for injecting inert gas (nitrogen) into the tank. The whole equipment is skid mounted, convenient for transportation and construction.
 
 
 
Tank cleaning is a dangerous operation in tank, because oil vapor is not only flammable, explosive and toxic. Therefore, the following safety regulations must be strictly observed during tank washing:
 
 
 
1. Open the manhole, check the oil quality at the bottom of the tank layer by layer, and determine the oil storage, drainage and treatment scheme;
 
 
 
2. The personnel entering the tank must wear work clothes, work shoes, work gloves and gas masks. Signal rope and safety belt shall also be taken, and special person outside the tank shall be assigned for monitoring. The time of entering the tank shall not be too long, generally 15-20min, and shift operation is preferred. In addition, medical personnel shall be on duty on site;
 
 
 
3. Brooms or wooden tools shall be used for cleaning residual oil and sewage, and iron and steel tools are strictly prohibited;
 
 
 
4. Effective ventilation shall be adopted;
 
 
 
5. Steam method: at the beginning, all the covers in the tank shall be closed. When the temperature reaches 60-70 ℃, the cover shall be opened to continue the steam washing until the residual oil in the tank is completely dissolved.
 
 
 
The cleanness of oil tank affects the quality of oil products. If the oil tank is not treated, the pipeline will be blocked, scaling and corrosion, and the quality of oil products will be low, such as oil tank leakage due to corrosion, crude oil pollution, etc. The service life of oil storage tank is generally long. After a period of use, impurities in crude oil will deposit on the bottom and wall of the tank, which will reduce the effective capacity of the tank and affect the efficiency of the tank. The long-term use of the oil tank will cause corrosion and leakage. If the inspection of the oil tank is ignored, it will bring us serious security risks and threaten the safety of the surrounding environment and the oil tank area.
