Abstract

The utility model discloses an oil-containing waste cleaning treatment device suitable for an offshore platform, which comprises a treatment box, the treatment box is a cylindrical box body, the bottom end of the treatment box is provided with a mounting table, the side wall surface of the upper end of the treatment box is provided with connecting pipelines at equal intervals, and liquid containing oil-containing waste is fed into the treatment box through the connecting pipelines; and the oil-containing waste is cleaned and separated. According to the oil-containing waste cleaning treatment device suitable for the offshore platform, the overall occupied area is reduced through the cylindrical structure of the treatment box, meanwhile, through multi-layer arrangement in the treatment box, the treatment difficulty of waste liquid generated after caisson wall plates, bottom plates and the like are subjected to automatic cleaning operation is further lowered, and through separation and recycling treatment of separated oil-containing waste, the oil-containing waste can be recycled. The energy burden of the offshore platform is reduced, the operation cost is reduced, meanwhile, the treatment efficiency of the oil-containing waste is improved, a large amount of waste can be quickly and effectively treated, accumulation of the waste on the offshore platform is reduced, and normal operation of platform operation is guaranteed.
