Description

TECHNICAL FIELD

[0001] The utility model relates to the field of water surface cleaning, especially to water surface oil cleaning ship. BACKGROUND

[0002] In recent years, with the acceleration of urbanization, people's requirements for water environment are getting higher and higher. When encountering heavy rainfall, mixed water containing kitchen grease, ground sediment pollutants and oil pollution in pipe network can easily break through the carrying capacity of sewage treatment facilities and directly enter the urban inland river through the flood discharge channel. After such grease-rich sewage enters open water, it will form a large area of surface oil film pollution, not only damaging the water ecological environment, but also seriously affecting the life quality of residents along the coast due to its continuous emission of odor. The current conventional emergency treatment means mainly adopts two ways of chemical dispersant decomposition or oil-absorbing material collection: the former can temporarily eliminate visual pollution, but will cause secondary pollution of water body and accelerate the dissolution and diffusion of oil materials; the latter can realize physical recovery of pollutants, but has problems of large consumption of adsorption medium, low efficiency of manual salvage and high operation cost. Especially in the special operation environment of narrow urban river, there is still a lack of related equipment that can independently complete oil collection. Therefore, how to design an oil collection equipment that does not cause secondary pollution of chemical agents, has low cost and high salvage efficiency has become a technical problem to be solved at present.

A first bin partition plate is arranged between the second oil treatment bin and the oil storage bin. The oil extraction device comprises an oil extraction pump, a first water inlet pipe and a first water outlet pipe. One end of the first water inlet pipe is in communication with the water surface of the second oil treatment bin, and the other end is connected with the oil extraction pump. One end of the first water outlet pipe is in communication with the oil extraction pump, and the other end is in communication with the oil storage bin. The collection port, the first oil treatment bin, the second oil treatment bin and the oil storage bin are sequentially arranged on the ship body.

[0004] Thus, the sewage with oil stains enters the first oil stain treatment bin through the collecting port, the primary concentrated oil stain sewage floating on the upper layer of the first oil stain treatment bin enters the second oil stain treatment bin through the oil spill board, and the secondary concentrated oil stain sewage floating on the upper layer of the second oil stain treatment bin is extracted to the oil stain storage bin through the oil stain extraction pump and the first water outlet pipe. Since the density of oil is smaller than that of water, the oil stains float on the surface of water, and through two-stage screening, the secondary concentrated oil stain sewage in the oil stain storage bin has a higher oil content and can be concentrated for treatment. The whole process adopts a pure physical method to concentrate oil stains, does not pollute the environment due to chemical agents, does not use high-cost adsorption consumables, and can remove the surface oil stains in an environmentally friendly, efficient and low-cost manner.
