Solution Overview
Problem
Current oil spill cleanup methods, such as using emulsifying agents and oil absorbent fabrics, face inefficiencies and secondary pollution issues, and existing equipment like oil skimmers collect excessive water, reducing oil collection efficiency and leading to sludge accumulation problems.
Innovation Solution
A rotating type foreign substance collection equipment featuring a screw body with a spiral wing and a separation membrane that allows water to penetrate while trapping oil, utilizing a porous, hydrophilic separation membrane and a storage system to enhance oil collection efficiency and prevent sludge accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional oil skimmer is used to collect oil, then oil can be collected from the water surface, but a larger amount of water is collected along with the oil, resulting in low oil collection efficiency
Solution Approach 1:
The patent employs a screw type oil collection component with porous characteristics that allows water to pass through while retaining oil on the surface. The porous structure enables selective permeation based on fluid properties, allowing the system to collect oil efficiently while discharging water through the separation membrane, thereby resolving the contradiction between oil collection efficiency and water collection amount
Solution Approach 2:
The separation membrane is applied specifically to the screw type oil collection component, creating a localized separation function. The membrane's selective permeability properties are concentrated at the critical interface where oil-water separation occurs, allowing water to pass through while oil is collected, thus improving oil collection efficiency without excessive water collection
2Reliability
If an abrasion resistant packing member is fitted to the screw outer peripheral surface to prevent direct contact with the water filter, then the water filter is protected from abrasion, but sludge accumulates between the packing member and the water filter, causing increased maintenance costs and reduced treatment efficiency
Solution Approach 1:
The patent removes the packing member component entirely from the screw type oil collection component design. By eliminating the packing member, the source of sludge accumulation is removed, while the screw component directly contacts the water-filtering system in a controlled manner that prevents filter damage, thus resolving the contradiction between filter protection and treatment efficiency
Solution Approach 2:
The screw type oil collection component is designed to perform both oil collection and water filtration functions without requiring additional protective packing members. The component's own structure provides the necessary protection and separation functions, preventing sludge accumulation while maintaining filter durability and treatment efficiency
