Description

technical field

[0001] The present invention relates to the technical field of cleaning equipment for oil storage tanks, in particular to cleaning equipment for the bottom surface of an oil storage tank, and also relates to an oil storage tank including the cleaning equipment for the bottom surface. Background technique

[0002] In the process of crude oil extraction, tiny particles in the oil reservoir, a small amount of mechanical impurities, sand, soil, heavy metal salts, and heavy oily substances such as paraffin and asphalt will naturally sink due to their high specific gravity. When crude oil is stored in the oil storage tank When it accumulates at the bottom of the oil tank, it forms a black and thick gelatinous substance layer, which is the bottom sludge of the oil tank. The sludge at the bottom increases with the continuous storage and transportation time, which seriously affects the storage and transportation production of the oil tank. It must be regularly to clea...
