Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oil-water separation devices are ineffective for handling oily water containing highly viscous oil, as the narrow flow passages lead to functional failures due to oil attachment, and the complexity of tar and particle removal increases the device's structure size.
Innovation Solution
An oil-water separation device with a horizontal flow passage and distinct recovery ports for oil components based on specific gravity, utilizing a cylindrical barrel and concentric members to separate oil from water without narrow passages, and incorporating a refining device with a spray tower and mist separator to handle highly viscous gases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional oil-water separation devices with narrow flow passages are used, then oil separation efficiency is improved, but highly viscous oil attaches to block the flow passage causing functional failure
Solution Approach 1:
The flow passage is divided into multiple sections by partitioning plates, creating a multi-stage separation process. This segmentation allows the oil-water mixture to be processed in stages, preventing viscous oil from blocking the entire passage at once while maintaining effective separation area.
Solution Approach 2:
The invention transitions from horizontal flow passages to vertical flow passages. This dimensional change allows gravity to act more effectively on the viscous oil, preventing it from adhering to and blocking the passage walls, while maintaining sufficient contact time for separation.
2Reliability
If multiple separation stages are added to remove tar and particles, then removal efficiency is improved, but device structure complexity and size increase
Solution Approach 1:
Multiple separation functions (oil-water separation, tar removal, and particle removal) are merged into a single integrated device with partitioning plates that create multiple stages within one structure. This combines several separation processes that would traditionally require separate devices, reducing overall complexity while maintaining high removal efficiency.

AI summary
This oil-water separation device includes: a supply port (3b) for oily water; a flow passage that causes oily water (X4, X7) supplied from the supply port to flow so that a flow component in a horizontal direction is a main flow component; a floated oil recovery port (F) provided above an upper portion of the flow passage and also at a position spaced from a start end of the flow passage; and a settled oil recovery port (T) provided beneath the flow passage. According to the oil-water separation device, it is possible to separate an oil component from oily water that contains an oil component with higher viscosity.
