Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing moisture from compressed air, such as freeze dryers and adsorption dryers, are inefficient and require large spaces, as they either leave residual moisture or necessitate pre-cooling and large area coverage.
Innovation Solution
A drying and filtering device integrating refrigerating and adsorption drying tubes on a shared base, where pre-cooled airflow is directed through adsorption drying tubes for efficient moisture removal, with alternating groups of tubes for adsorption and regeneration to enhance efficiency and reduce overall device volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a freeze dryer is used to remove moisture from compressed air, then the moisture is condensed into liquid water, but the drying dew point temperature must be above zero to prevent pipeline blockage, resulting in incomplete moisture removal
Solution Approach 1:
The patent combines the freeze dryer and adsorption dryer into a single integrated system where the freeze dryer performs preliminary cooling and condensation, and the adsorption dryer completes the drying process. This merging allows the system to achieve complete moisture removal while maintaining manageable temperature levels throughout the process.
Solution Approach 2:
The freeze dryer performs preliminary cooling and condensation of moisture before the air enters the adsorption dryer. This preliminary action removes the bulk of the moisture, making the subsequent adsorption process more efficient and allowing the system to achieve complete drying without requiring the entire system to operate at extremely low temperatures.
2Reliability
If an adsorption dryer is used to fully dry compressed air, then complete moisture removal is achieved, but a pre-freeze dryer is required to cool the compressed air first, covering a large area
Solution Approach 1:
The patent merges the freeze dryer and adsorption dryer into a compact integrated unit with shared structural components, such as a common shell and coordinated internal arrangements. This merging significantly reduces the total area occupied compared to having separate pre-freeze dryer and adsorption dryer units.
Solution Approach 2:
The design nests the refrigerating tube and adsorption drying tubes within a shared bearing base structure. The refrigerating tube is positioned centrally with adsorption drying tubes arranged around it, creating a nested configuration that maximizes space utilization and minimizes the overall device footprint.
3Reliability
If separate pre-freeze dryer and adsorption dryer are arranged on the pipeline path, then moisture removal is achieved, but the device volume is large
Solution Approach 1:
The patent combines both drying functions into a single integrated device with unified structural support (shared bearing base), reducing the total volume compared to separate units connected in series on the pipeline.
Solution Approach 2:
The refrigerating tube and adsorption drying tubes are nested within the same bearing base structure, with components arranged concentrically and vertically to minimize the overall volume of the dryer system while maintaining functional effectiveness.
