Closed vehicle-mounted integrated cleaning device for cleaning petrol station oil storage tank

Abstract

The invention discloses a closed vehicle-mounted integrated cleaning device for cleaning a petrol station oil storage tank. The closed vehicle-mounted integrated cleaning device comprises a first detection vehicle, a second detection vehicle, and a cleaning tooling fixed to the oil storage tank, wherein a cleaning unit, a liquid recycling unit, a gas detection unit and a liquid filter unit are integrated on the first detection vehicle; an oil gas recycling unit, an inert gas generation unit and an independent power supply unit are integrated on the second detection vehicle; the cleaning tooling comprises a manhole disc, a liquid suction connection pipe and a cleaning pressing connection pipe; the manhole disc is detachably connected with an oil filling hole in the oil storage tank; the liquid suction connection pipe and the cleaning pressing connection pipe are arranged on the manhole disc; the lower ends of the liquid suction connection pipe and the cleaning pressing connection pipe penetrate through the manhole disc to stretch into the oil storage tank; a spray nozzle is fixedly arranged at the lower end of the cleaning pressing connection pipe; and a nitrogen injection hole, anoil gas detection hole and an oil gas recycling hole are sequentially formed in the manhole disc. According to the closed vehicle-mounted integrated cleaning device, mechanical cleaning is adopted, labor intensity is greatly reduced, personnel safety is guaranteed, and cleaning efficiency of the oil storage tank is improved.

Description

technical field [0001] The invention relates to the technical field of cleaning oil storage tanks in gas stations, in particular to a closed vehicle-mounted integrated cleaning device for cleaning oil storage tanks in gas stations. Background technique [0002] Gas station oil storage tank is a container for storing oil products, and it is the main equipment for refined oil products. 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 oi...

Problems solved by technology

[0005] In the prior art, manual cleaning directly discharges oil and gas into the atmosphere, which is not environmentally friendly, and is likely to cause personnel poisoning and oil tank explosions. Therefore, the use of mechanized cleaning has become a necessary measure to solve these problems

[0006] In view of the manual cleaning in the prior art, the oil and gas are directly discharged into the atmosphere, which is not environmentally friendly, and is likely to cause personnel poisoning and oil tank explosions. At present, no effective solution has been proposed.
