Integrated Membrane Module for Space-Constrained Liquid Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Systems incorporating separation membrane modules often face space constraints, limiting their occupancy area.
Innovation Solution
A separation membrane module is designed with a container housing both a degassing membrane element and a separation membrane element, where the degassing membrane element is positioned upstream or downstream of the separation membrane element in the flow direction of the liquid to be treated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If separate containers are used for degassing membrane element and separation membrane element, then each element can be independently maintained, but the system occupies more space
Solution Approach 1:
The patent combines the degassing membrane element and separation membrane element into a single integrated container, allowing both membrane elements to coexist in one housing. This merging approach reduces the total number of containers needed while maintaining the functional independence of each membrane element through separate flow paths and chambers within the unified structure.
Solution Approach 2:
The patent employs a nested configuration where the degassing membrane element and separation membrane element are arranged concentrically or in overlapping spatial arrangements within the same container. This nesting strategy maximizes space utilization by placing one membrane element inside or adjacent to the other, thereby reducing the overall footprint while preserving independent functionality.
2Area of stationary object
If multiple membrane elements are integrated in one container, then space is saved, but device complexity increases
Solution Approach 1:
The patent divides the integrated container into distinct functional segments or chambers, each housing a specific membrane element with its own flow inlet and outlet. This segmentation strategy organizes the complex internal structure into manageable, modular sections that are easier to design, manufacture, and maintain, thereby reducing the perceived complexity despite the integrated configuration.
Solution Approach 2:
The patent designs the container and internal components to serve multiple functions simultaneously - the same structural elements provide support, separation, and flow distribution for both membrane elements. This multi-functionality approach reduces the total number of separate components needed, simplifying the overall device while achieving space savings through integration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively reduces the occupied space by integrating both membrane elements within the same container, enhancing space savings and maintainability while maintaining effective treatment performance.
Implementation Method 1
a degassing membrane element that is disposed inside the container and removes a dissolved gas from the liquid
Implementation Method 2
a separation membrane element that is disposed inside the container, is located upstream or downstream of the degassing membrane element in a flow direction of a liquid to be treated, and filters the liquid
