Description

Technical Field

[0001] The utility model relates to the technical field of comprehensive treatment of ship sewage oil, in particular to a device for producing ship fuel oil by comprehensive utilization of ship sewage oil. Background Art

[0002] At present, the amount of ship sewage oil (including residual oil in the backwash filter of the ship fuel system, oil separator sewage oil, sewage oil cleaned and leaked from the transportation system, sewage oil from the fuel oil tank, etc.) generated in the Beibu Gulf region is large, and there is a lack of effective resource utilization technology. There are certain environmental risks in cross-provincial transfer. Ship oil pollution treatment technology is still in constant innovation and development. Physical and chemical technology and biotechnology are generally used internationally. Physical and chemical technologies such as adsorption, centrifugation and sedimentation can effectively remove oil pollution; biotechnology such as biological adsorption and biodegradation has also been applied. When comprehensively treating and reusing ship sewage, it is first necessary to pre-treat the oil-water separation of the ship's oily wastewater collected by the ship's pollution-cleaning ship, and use mechanical centrifugation to separate the ship sewage oil for disposal.

[0003] In the actual use of the prior art, the collected ship sewage is dumped into the centrifugal barrel inside the corresponding centrifuge, and then the centrifugal barrel is driven by the operation of an external drive motor. The centrifugal effect can separate the various liquids with different densities inside the ship sewage oil. After separation, some impurities and the separated oil body will adhere to the inner wall of the centrifugal barrel. The operator often manually holds the corresponding scraper to separate the adhered oil body and impurities. In this process, the labor consumption required for the operator to clean it is too large, which is time-consuming and laborious. At the same time, it is impossible to simultaneously scrape and remove impurities on both sides of the inner wall of the barrel, which affects the subsequent normal reuse of the centrifugal barrel. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content
