Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas purification apparatuses face challenges in compact design and efficient removal of sulfur oxides and other impurities due to contamination of gas purification agents by impurities like soot dust, which reduces reaction efficiency and complicates reutilization of the agents.
Innovation Solution
A compact gas purification apparatus design where both the filter portion for removing impurities and the gas purification agent are housed in a single unit, with the gas purification agent positioned downstream of the filter to minimize contamination and facilitate separate retrieval of used agents and impurities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the gas purification agent is injected into exhaust gas containing soot dust, then the apparatus can be compact with both filtration and purification in one housing, but the gas purification agent becomes contaminated with soot dust, reducing reaction efficiency
Solution Approach 1:
The internal space of the housing is divided into a first space for filtration and a second space for gas purification, separated by a partition wall with communication holes. This segmentation allows the gas purification agent to contact only purified gas while maintaining a compact single-housing structure.
Solution Approach 2:
The partition wall with communication holes acts as an intermediary structure that allows purified gas to pass from the first space to the second space, enabling the gas purification agent to receive clean gas without direct contact with soot dust in the upstream exhaust.
2Ease of operation
If dust removal and gas purification are carried out in separate housings, then the gas purification agent remains clean for easy reutilization, but the size of the apparatus increases
Solution Approach 1:
The filtration function and gas purification function are merged into a single housing, with the partition wall enabling functional separation. This allows the gas purification agent to be easily retrieved and reutilized while maintaining a compact apparatus size.
Solution Approach 2:
The partition wall with communication holes creates a nested spatial arrangement where the second space (gas purification) is positioned downstream within the same housing, allowing efficient use of space while maintaining functional independence for agent retrieval.
3Productivity
If the gas purification agent is disposed downstream of the filter portion, then contamination is reduced and reaction efficiency improves, but the apparatus design becomes more complex
Solution Approach 1:
The partition wall is provided with communication holes at specific locations to allow purified gas to reach the gas purification agent. This localized structural feature enables efficient gas purification while maintaining overall design simplicity.

AI summary
A gas purification apparatus includes: a housing to which a gas is introduced; a filter portion for removing an impure substance in the gas from the gas, the filter portion being disposed inside the housing; and a gas purification agent for removing a removal target substance in the gas from the gas, the gas purification agent being disposed, inside the housing, on the filter potion or in a space at a downstream side of the filter portion with respect to a flow of the gas.
