Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas coolers using vortex tubes have insufficient cooling effects due to compressed air absorbing ambient heat during transportation, leading to increased temperature and reduced efficiency, and additional cooling units consume more energy without effectively lowering the cooling temperature.
Innovation Solution
A modular reflux sampler with a condenser container and vortex tube system where the compressed air duct passes through the condenser, pre-cooling the air before it enters the vortex tube, and the cold air nozzle cools the gas pipeline, with a spirally wound duct increasing contact area for enhanced cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If compressed air is transported through a normal-temperature gas supply pipeline to the vortex tube, then the vortex tube can receive sufficient compressed air for cooling, but the compressed air absorbs ambient heat during transportation causing temperature increase and reduced cooling effect
Solution Approach 1:
The compressed air duct is pre-cooled by the cold air from the vortex tube before the compressed air enters the duct. This preliminary cooling action reduces the temperature of the compressed air before it absorbs ambient heat during transportation, thereby maintaining lower temperature throughout the supply process while ensuring sufficient compressed air reaches the vortex tube.
2Temperature
If additional cooling units are added to cool the compressed air before it enters the vortex tube, then the compressed air temperature can be reduced, but energy consumption increases
Solution Approach 1:
The system uses the cold air generated by the vortex tube itself to pre-cool the compressed air duct. This self-service approach eliminates the need for external cooling units, reducing energy consumption while effectively lowering the compressed air temperature before it enters the vortex tube.
Solution Approach 2:
The cold air from the vortex tube acts as an intermediary cooling medium that transfers coldness to the compressed air duct. This intermediary approach provides efficient cooling without requiring additional energy-consuming cooling equipment.
3Speed
If the number of vortex tubes is increased to provide more cold air, then the cooling speed can be accelerated, but the cooling temperature cannot be reduced sufficiently
Solution Approach 1:
Instead of increasing the number of vortex tubes, the invention pre-cools the compressed air duct using cold air from the vortex tube before the compressed air enters. This preliminary action ensures that even with the same number of vortex tubes, the cooling temperature is sufficiently reduced because the compressed air starts at a lower temperature.
