Gas Supply Filter Heating to Prevent Deliquescence Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas supply devices and container refrigeration systems face difficulties due to increased pressure loss and salt damage from deliquescence in humid environments, which hinder air passage through filters.
Innovation Solution
Incorporating a heating unit that heats the gas flowing into the filter when salt and humidity levels exceed certain thresholds, along with a salt amount detection unit and humidity detection unit, to prevent deliquescence and maintain filter efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter is used in a humid environment with salt particles, then the filter can remove particles from the air, but the pressure loss increases due to deliquescence
Solution Approach 1:
The heating unit pre-heats the air before it reaches the filter to prevent deliquescence from occurring. By raising the temperature above the deliquescence point, the filter remains dry and maintains low pressure loss throughout operation.
Solution Approach 2:
The system changes the temperature parameter of the air stream to prevent deliquescence. The heating unit raises the air temperature above the deliquescence temperature, fundamentally altering the physical state conditions to prevent moisture absorption and pressure loss.
2Reliability
If the heating unit continuously heats the gas, then deliquescence is prevented, but energy consumption increases
Solution Approach 1:
The control unit receives input from the humidity sensor and pressure loss sensor to determine when heating is necessary. The system activates the heating unit only when humidity exceeds a threshold or pressure loss indicates deliquescence, optimizing energy usage while maintaining filter performance.
Solution Approach 2:
The heating system transitions from a static continuous operation to a dynamic conditional operation. The heating unit's activation state changes based on real-time environmental conditions and filter performance metrics, allowing the system to adapt energy consumption to actual needs.
