Abstract

A closed cleaning device for an oil reservoir comprises an oil tank to-be-cleaned, the oil reservoir, a craft valve island, a pressurizing pump, and a vacuum heat exchange oil-water separator, wherein pollution discharge pipes are mounted at both the bottoms of the oil tank to-be-cleaned and the oil reservoir; valves are mounted on the pollution discharge pipes; a vacuum pipe, a steam pipe, an oil outlet pipe, a liquid level meter, a separator outlet pipe and a separator inlet pipe, which are provided with valves, are mounted on the vacuum heat exchange oil-water separator respectively; the pollution discharge pipe at the bottom of the oil tank to-be-cleaned is connected with the craft valve island through a pipeline; the craft valve island is connected with a cleaning machine through a pipeline mounted with a valve; the pollution discharge pipe of the oil reservoir is connected with the craft valve island through a pipeline. The closed cleaning device has the advantages that the cleaning technology is simple; the device is connected with the pipelines to form a sealed circulating system; on-site fuel gas leakage is avoided; the size, manufacture cost and energy consumption are reduced; the safety is greatly improved; the transportation is convenient.

Description

technical field [0001] The invention relates to a decontamination process for an oil storage tank, in particular to a closed cleaning process and equipment for an oil storage tank. Background technique [0002] With the increase of domestic refined oil and crude oil stocks, the construction and use of oil storage tanks have also increased rapidly. In addition, the sulfur content of crude oil is increasing year by year, and the corrosion of oil storage tanks is intensified, which shortens the maintenance cycle of oil storage tanks. Due to the uncontrollability of the safety of manual cleaning of oil storage tanks, relevant state departments have banned manual cleaning of oil storage tanks, and vigorously advocated mechanical cleaning of oil storage tanks. However, the existing domestic mechanical cleaning oil storage tank equipment is all imported from abroad or domestic imitation, which is not only expensive, but also bulky, which brings great inconvenience to transportati...
