Abstract


With the rapid development of china’s economy, it demands an increasing amount of petroleum and the transportation of petroleum is booming as well. The accident of oil spill that happens frequently leads to quantity of oil leaks into the sea environment and brings catastrophic destroy to local ecological condition. Once the oil spill occurs, an in-time and efficient measures must be taken in order to clean the oil spill. Otherwise, it would make a catastrophic harm to the marine environment and ecological resources. Nowadays, there are physical methods, biological methods and chemical methods to deal with the oil spill in the sea. Among these methods, mechanical recovery method can not only clean the oil and protect the sea environment but also recover the valuable petroleum resource, therefore it becomes the most widely used technology in dealing with the oil spill right now. However,to some extent, the existing mechanical recovery equipments have low capability and poor performance, complicated structure and high requirements of environment, remained to be improved.This thesis bases on the advantages and disadvantages of various oil spill recovery methods. In view of the present difficulty in recovering high viscosity oil spill. This thesis design a new oil spill recovery equipment in order to realize efficient recovery of oil spill with high viscosity. This thesis mainly includes the following work:1. According to the actual working condition of drum oil skimmer, using the Navier-Stokes theorem, This thesis establishes the adhesion of the mathematical model and then lays a theoretical foundation for further improvement and optimization.2. A new type of double-sided drum oil skimmer, initiated in the hope of geting the affecting factors of adhesive thickness and discharge which can be got through mathematical model and the methodology of using Pro-E, Auto-CAD software to build 3D model of the adhesion oil spill recovery facility, are reported here.3. Backed by valve-control-motor hydraulic system working principle, the two-sided drum abandoned oil pot has been designed and select some hydraulic components of hydraulic system, while using power bond graph of hydraulic system model and simulates hydraulic system. The analysis results indicates that the system design can well meet the design requirements.4. The speed control of the designing double-sided drum oil skimmer is researched under Matlab/Simulink environment.According to simulation analysis, the results show that the fuzzy PID control good realized system control requirements.
