Absorption Cell Dust Prevention via Dual-Layer Density Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chemical absorbents for odorous gases face issues such as dust particle generation from low-density absorbents and low odor removal rates due to high-density absorbents' low air diffusion properties, leading to secondary contamination and reduced effectiveness.
Innovation Solution
An absorption cell design featuring a first absorption layer coated with a second, high-density absorption layer to prevent dust particle generation and enhance odor removal, where the second layer includes pore parts for fluid flow and protrusion parts for increased surface area, and a manufacturing method involving a protective layer formed from a low-carbonizing point material to create these features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If low-density chemical absorbents are used, then dust particles are generated, but if high-density chemical absorbents are used, then air diffusion rate decreases
Solution Approach 1:
The absorption cell is divided into multiple absorption layers with different densities. The first absorption layer (lower density) provides high air diffusion rate, while the second absorption layer (higher density) prevents dust particle generation. This segmentation allows each layer to optimize its function without compromising the other.
Solution Approach 2:
Different regions of the absorption cell are assigned different absorbent densities based on local functional requirements. The inner region uses lower density absorbent for rapid air diffusion, while the outer region uses higher density absorbent for dust prevention. This local quality differentiation resolves the contradiction between diffusion rate and dust control.
2Object-affected harmful factors
If high-density chemical absorbents are used, then dust particle generation is reduced, but odor generating substance removal rate decreases
Solution Approach 1:
The absorption cell is divided into multiple absorption layers with different densities. The first absorption layer (lower density) provides high air diffusion rate, while the second absorption layer (higher density) prevents dust particle generation. This segmentation allows each layer to optimize its function without compromising the other.
Solution Approach 2:
The absorption cell uses a composite structure combining different absorbent materials with different densities. The lower density absorbent provides rapid air diffusion and high removal rate, while the higher density absorbent provides dust prevention. The composite structure achieves both high productivity and low dust generation simultaneously.
