Purge Device with Internal State Detection for Gas Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional purge devices face challenges in appropriately purging containers with varying gas loads, leading to inefficient use of purge gas, as the supply amount is often insufficient for containers with sufficient gas loads and excessive for those with insufficient loads, resulting in wasted gas.
Innovation Solution
A purge device equipped with an internal state detector that assesses the container's state before purging, using exhaust gas composition analysis to determine optimal purge conditions, including flow rate and supply time, ensuring tailored purging for each container, thereby reducing waste and optimizing gas usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the supply amount of purge gas is set to be small with reference to a container that is carried in with sufficient loading of the purge gas, then the waste of purge gas is reduced, but the effect of purging on a container that is carried in with insufficient loading of the purge gas becomes insufficient
Solution Approach 1:
The system performs preliminary detection of the container's internal state (oxygen concentration, moisture content) before the purging process. Based on this preliminary information, the purging conditions are predetermined and optimized for each container's actual state, avoiding both over-purging and under-purging.
Solution Approach 2:
The system uses sensors to detect the internal state of containers and feeds this information back to the control device. The control device adjusts the purging parameters (flow rate, supply time) based on this feedback, creating a closed-loop control system that optimizes purge gas usage while ensuring effective purging.
2Reliability
If the supply amount of the purge gas in the current purging is set to be large with reference to a container that is carried in with insufficient loading of the purge gas, then the purging effect is sufficient, but the amount of wasted purge gas is larger than that of a container that is carried in with sufficient loading of the purge gas
Solution Approach 1:
The system applies different purging conditions to different containers based on their individual internal states. Each container receives a customized purging regimen (different flow rates, supply times) tailored to its specific oxygen concentration and moisture content, rather than applying a uniform purging strategy to all containers.
Solution Approach 2:
The system dynamically changes the purging parameters (flow rate, supply time, pressure) based on the detected internal state of each container. The control device adjusts these parameters in real-time to match the actual purging needs, optimizing both effectiveness and efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for precise control of the purging process, ensuring effective gas utilization while minimizing waste, by determining purge conditions based on real-time container state detection, thus providing efficient and cost-effective purging.
Implementation Method 1
the internal state detector may detect the internal state of the container based on a composition of an exhaust gas that is discharged from the container when the purge gas is supplied to the container
Implementation Method 2
the internal state detector may detect a concentration of moisture or oxygen in the exhaust gas, and may detect the internal state of the container based on a detection result of the concentration

AI summary
A purge device capable of appropriately purging a container while saving purge gas includes a first purge nozzle that supplies a purge gas to a container to be purged, an internal state detector capable of detecting an internal state of the container before a purging process with the first purge nozzle is started, and a purge determiner that determines purge conditions for the container based on a detection result from the internal state detector.
