Oil drop catcher of inverted fluidized bed

The invention discloses an oil drop catcher of an inverted fluidized bed. The oil drop catcher comprises a fluidized bed, a liquid charge system, an in-bed packing concentration monitoring system and a gas charge system, wherein the fluidized bed comprises a cylinder body, an in-bed packing support element, an air distributing plate and in-bed packing which is arranged in the in-bed packing support element and the surface of which is covered by an oleophylic coating; by utilizing the characteristic that the density of a solid particle is less than that of a liquid, the in-bed packing moves up and down in a bed and is at a fluidized state in the bed, so that the in-bed packing solid particles and the oil-water mixture are mixed fully, and the in-bed packing of the oleophylic coating adsorbs the oil phase so as to achieve the aim of catching oil drops. The oil drop catcher of the inverted fluidized bed has the advantages of running stability, relatively high safety, simple structure, relatively high separation efficiency, operation simplicity and the like.
