储油罐机械清洗原理

储油罐机械清洗技术是将被清洗储罐底部具有流动性的油品移送至接收油罐，将清洗油供给罐中的油品经加温加压后通过清洗机搅拌、溶解罐内剩余凝固油，经过滤器清除杂质后移送至接收油罐，比较后用温水对储罐内各部位进行循环清洗，以达到罐内动火条件。在清洗过程中持续注人惰性气体至被清洗储罐，从而使其内部氧气浓度始终保持在8VoL%以下，防止爆炸等危险的发生;配备氧气及可燃气体检测装置，时刻监测被清洗储罐内的氧气及可燃气体浓度，确保机械清洗作业安全运行。

Mechanical cleaning technology of oil tank will be cleaning the bottom of the tank is transferred to the mobility of the oil receiving tank, cleaning oil supply tank in oil by heating and pressurizing by cleaning machine stirring and dissolving tank residual oil after solidification, filter to remove impurities after transferred to the receiving tank, at the end of each part of the storage tank for cleaning cycle with warm water, in order to achieve the conditions of hot pot. Continuous injection of inert gas to the tank to be cleaned in the cleaning process, so that the internal oxygen concentration remained below 8VoL%, to prevent the occurrence of explosion danger; equipped with oxygen and combustible gas detection device, time monitoring of cleaning oxygen and combustible gas in the tank concentration, to ensure safe operation of mechanical cleaning.

清洗流程1设备安装

Cleaning process 1 equipment installation

采用轻型管线及阀门快速完成设备的安装及管线的连接，并测试系统整体严密性;

Use light pipeline and valve to quickly complete the installation of the equipment and connection of the pipeline, and test the overall tightness of the system.

2油移送

2 oil transfer

通过移送模块将被清洗油罐中具有流动性的油品移送至接收油罐;

The flow of oil in the oil tank is transferred to the receiving oil tank through the transfer module.

3同种油清洗

3 the same kind of oil cleaning

清洗模块将清洗油供给罐中的油品经加温、加压后，通过设置在被清洗储罐单盘或罐侧壁检修孔上的清洗机对被清洗储罐内部凝固油进行击碎、溶解，使其具有较好的流动性，并通过移送模块过滤后移送至接收油罐;

The cleaning module will clean the oil supply tank in oil by heating and pressurizing, the cleaning machine is arranged in the tank wall of the tank or a single disk access hole on the break, the tank cleaning oil solidification dissolved, which has good fluidity, and through the transfer of the filtered transferred to the receiving module oil tank;

4温水清洗

4 warm water cleaning

由清洗模块对预先加人到油水分离模块中的清水进行加温、加压后，通过清洗机清洗储罐内各部位，利用油水分离模块分离温水清洗循环过程中的油水混合物，分离出来的油品由回收泵移送至接收油罐，分离出来的清水继续进行温水清洗循环作业。

To add to the advance of oil-water separation module in water for heating and pressurizing by cleaning module, through various parts of machine cleaning tank, the oil-water oil-water separation module separation warm water cleaning cycle in the mixture, the separated oil transferred from the pump to the receiving tank recovery, separated water to warm water cleaning cycle homework.

技术优势对比

Comparison of technical advantages

人工清洗储油罐作业人员从罐侧壁检修孔进人储罐内搭梯进行人工擦洗，储罐空间狭小，空气不流通，可燃性气体浓度高，易发生中毒和爆炸事故，施工作业环境恶劣，严重地损害作业人员的身心健康;另一方面，从罐内清除的污油及人工擦洗产生的大量污水造成罐区和周边地区环境的污染，同时较长的清洗周期(平均为二个月)降低了库区的储存调节能力，直接影响库区的正常生产，大量废弃的罐底油还造成资源浪费和环境污染。对比传统的储罐清洗方式，机械清洗技术实现了储罐全过程密闭清洗，具有清洗时间短、健康、安全、罐底油回收率高、社会效益及经济效益显著的特点。

The storage tank operating personnel manual cleaning from the tank wall cleaning ladder manhole Jinren tank, tank space, air circulation, combustible gas concentration is high, prone to poisoning and explosion accidents, the construction work environment is bad, serious harm to the health of workers; on the other hand, a large number of sewage removal from the tank of oil pollution caused by the environment and cleaning the tank and the surrounding area pollution, at the same time cleaning cycle (mean two months) reduced the reservoir storage adjustment ability, directly affect the normal production of the reservoir area, a large number of waste oil tank bottom also caused the waste of resources and environmental pollution. Compared with traditional tank cleaning methods, mechanical cleaning technology achieves closed storage tank cleaning process, which has the characteristics of short cleaning time, health, safety, high recovery rate of tank bottom oil, remarkable social and economic benefits.
