原油中含有少量的泥砂、水分等杂质,这些杂质沉积在储油罐的底部和附件上,使储油罐的有效容积减少,同时会对罐底板和罐壁板产生腐蚀,造成原油泄漏,存在重大的安全隐患。为了保护罐体、减少能源浪费、防止安全事故的发生,根据规定必须定期对储油罐进行清洗。目前我国绝大部分石化企业采用人工方式清洗储油罐,只有少数几家石化企业应用了储油罐机械清洗技术,储油罐机械清洗技术在我国尚处于应用起步阶段。
Crude oil contains a small amount of sediment, water and other impurities, these impurities deposited on the bottom of the tank and accessories, the effective volume of the tank to reduce, while the tank floor and tank wall will produce corrosion, resulting in leakage of crude oil, there A major security risk. In order to protect the tank, reduce energy waste and prevent accidents, the tank must be cleaned periodically according to regulations. At present, most petrochemical enterprises in our country use artificial way to clean storage tanks. Only a few petrochemical enterprises have applied the mechanical cleaning technology of storage tanks. The mechanical cleaning technology of storage tanks is still in the initial stage of application in our country.
