油罐是贮运系统的主要工艺设备之一。原油中所含的水份、蜡、胶质、沥青质往往形成固体沉淀物沉入罐底。这种以蜡为主的沉淀物,使油罐的有效容积减少,使用寿命缩短,浪费能源。为了消除罐底沉淀物,目前国内一般采用原始的人工清罐方法,既费时、费力、费能源,又污染环境。如果在原油罐中安装搅 Oil tank is one of the main process equipment for storage and transportation system. Crude oil contained in the water, wax, gum, asphaltenes often form a solid precipitate sink into the tank bottom. This wax-based sediment, the tank to reduce the effective volume, shortened life expectancy, a waste of energy. In order to eliminate the sediment at the bottom of the tank, at present, the original domestic manual tank cleaning method is adopted, which takes time, effort, energy and polluting the environment. If installed in the crude tank stir
