Device for cleaning oil tank pneumatic energy

The utility model relates to a device for cleaning oil tank pneumatic energy, which is characterized in that the device comprises multi-channel of annular pipelines (4) which are fixedly arranged on the bottom portion of an oil tank through an overhead mode, the multi-channel of annular pipelines are respectively communicated with gas transmission pipelines (6) through communication pipe fittings, and a plurality of nozzles (5) whose spouts toward the bottom of the tank are arranged around the bottoms of the annular pipelines. The device for cleaning oil tank pneumatic energy not only can save the man power and material resources of cleaning the bottom portion of the oil tank, greatly increases the cleaning work efficiency, can reduce the oxygen concentration in the tank through the mode of injecting inert gas to the tank from a lower nozzle, achieves the controlled atmosphere reserve of low oxygen or oxygen lack, reduces the oil oxidation, and guarantees the safety of oil storage.
