Oil storage tank robot cleaning system and method

Abstract

The invention discloses an oil storage tank robot cleaning system and method, and belongs to an oil storage tank cleaning process and system. The cleaning process includes the steps of manhole cover opening, oil product transferring, nitrogen replacing, tank entrance of a robot, oil storage tank cleaning, tank exit of the robot, sewage recovering, ventilating, manual checking and manhole cover installing. The cleaning system comprises the cleaning robot, a reeling and unreeling device, a power device, a monitoring device, a sewage recovering device, a gas replacing device and a water feed device. The cleaning system is characterized in that a 180-degree cleaning mode, a linear turning-back path and a fixed point cleaning scheme are adopted in oil storage tank cleaning, and system equipment has the corresponding explosive-proof grade according to the explosiveness and fatalness region where the system equipment is located. The oil storage tank robot cleaning system is convenient to use, reliable in performance, economical, practical and capable of achieving automatic cleaning without tank entrance of staff.

Description

technical field [0001] The invention relates to the field of oil storage tank cleaning, in particular to a robot cleaning system and method for an oil storage tank. Background technique [0002] Utilizing storage tanks for storage is the main way of strategic petroleum reserves. During the long-term storage and transportation of refined oil storage tanks, a small amount of sand, soil, heavy metal salts and other impurities in the refined oil will settle and accumulate at the bottom of the storage tank together with water due to the density difference, forming a black and thick gel Substance, that is, oil storage tank bottom sludge. Impurities and moisture will reduce the quality of refined oil and affect the accuracy of oil product calculation; accelerate the corrosion of oil storage tanks, and in severe cases will cause perforation of the bottom plate, resulting in oil leakage accidents; generate and accumulate static electricity, resulting in static electricity accidents....

AI Technical Summary

Problems solved by technology

Impurities and moisture will reduce the quality of refined oil and affect the accuracy of oil product calculation; accelerate the corrosion of oil storage tanks, and in severe cases will cause perforation of the bottom plate, resulting in oil leakage accidents; generate and accumulate static electricity, resulting in static electricity accidents

In addition, when the oil product is upgraded or replaced with different oil products, the remaining oil in the tank and the newly loaded oil cannot be mixed, and when the oil storage tank leaks or is damaged, it needs to be inspected or hot repaired. Oil storage tanks are cleaned, and oil storage tanks must also be cleaned and repaired regularly according to national regulations
