Oil fields, refineries and chemical plants in the petrochemical industry all have a large number of oil tanks, and a large part of the bottoms of the oil tanks can deposit a certain amount of water. Before entering the next working procedure, the water at the bottom of the oil tank must be removed completely to ensure normal production and qualified product quality. The general dewatering operation is to drain the water at the bottom of the oil tank by means of a dewatering device, and the drained water not only contains a certain amount of oil which is not completely separated, but also contains a great amount of toxic and harmful gases such as hydrogen sulfide and sulfur dioxide. The traditional dehydration mode is to remove water at the bottom of the oil tank, discharge the water into a dehydration tank and convey the water to a sewage treatment plant through an underground sewage pipeline.
However, the dewatering mode has the following disadvantages: firstly, a large amount of toxic and harmful gases contained in the sewage volatilize into the air to pollute the air, and particularly when the content of hydrogen sulfide in the sewage is high, the life safety of operators is threatened; secondly, once leakage occurs in the underground sewage pipeline, soil and underground water can be polluted, and irreparable pollution is caused in a short period; thirdly, when the operator fails in dehydration or the dehydrator fails in dehydration, a large amount of medium stored in the oil tank leaks out of the tank, so that the environment is polluted, and huge potential safety hazards are caused.
