Marine oil spill recovery device based on air grid

The invention provides a marine oil spill recovery device based on an air grid, and belongs to the field of marine oil spill recovery devices; the marine oil spill recovery device based on the air grid is placed on the sea surface, an air pump, a water pump and an oil pump are placed on a ship, a water suction pump and the air pump are turned on, pressure in an oil cleaning device box body is lowered, the water enters the oil cleaning device box body through an oil water round tube, and high pressure gas passes out from a nozzle through a high pressure pipe, and emulsifier from an emulsifier box is atomized into a circular tube grid. Since the upper end of a round tube is provided with air holes, the gas overflows from the air holes and floats upward with a small density of oil. At the same time, the emulsifier makes the oil become free, and makes bubbles float up to the surface easier. A funnel-type oil cover contacts the oil surface to form a closed space, and then the oil pump pumpsthe floating oil for recycling. The marine oil spill recovery device based on the air grid utilizes the bubble to make the physical method of oil and water layer to separate and recover the oil and water, has the characteristics of green environmental protection, convenient and easy operation, high recovery efficiency, and application prospect is broad.
