Problem
Remote environmental sensing and analysis systems, particularly those with optical elements, are prone to contamination from dust, dirt, and water, which affects data accuracy and can lead to system failure, requiring frequent maintenance and being costly due to inaccessibility.
Innovation Solution
A cleaning element that induces vortex flow in a sample gas stream to separate contaminants, such as dust and water droplets, using materials like metals and plastics, which can be integrated into sample gas analyzers to maintain cleanliness and extend system lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gas analyzer is placed in remote locations for environmental monitoring, then data collection capability is improved, but contamination from dust and water increases
Solution Approach 1:
The cleaning element performs preliminary cleaning of the gas sample by removing dust and water droplets before the sample enters the optical sensing components. This preventive action protects the optical elements from contamination, maintaining measurement accuracy without requiring frequent maintenance of remote deployed units.
2Measurement precision
If optical elements are used in the gas analyzer, then sensing capability is improved, but sensitivity to contaminants increases
Solution Approach 1:
The cleaning element acts as an intermediary component between the contaminated gas sample and the optical sensing elements. It removes harmful contaminants (dust, water droplets) from the gas stream before the cleaned sample reaches the optical components, thereby protecting the sensitive optical elements while maintaining their high sensing capability.
3Reliability
If the system operates for long periods without maintenance, then operational reliability is improved, but contamination accumulation worsens
Solution Approach 1:
The cleaning element operates continuously throughout the system's operational life, providing ongoing removal of contaminants from the gas sample. This continuous cleaning action maintains measurement accuracy and prevents contamination accumulation, enabling the system to operate reliably for extended periods without maintenance intervention.
4Duration of action of stationary object
If cleaning elements are added to the system, then maintenance intervals are prolonged, but device complexity increases
Solution Approach 1:
The cleaning element is designed as a passive, maintenance-free component that automatically removes contaminants from the gas sample using the kinetic energy of the flowing gas itself. The design requires no external power source, moving parts, or complex control systems, thereby extending maintenance intervals without significantly increasing device complexity.

AI summary
In one example, a sample gas analyzer includes a sample cell configured to receive a gas sample, a sample tube including a passageway that is in communication with the sample cell, and an intake portion. A cleaning element is disposed between, and arranged for fluid communication with, the sample tube and the sample cell, and includes a body having a chamber configured to aid in imparting a rotational motion to a fluid stream entering the chamber. The cleaning element also includes an inlet port that is in communication with the chamber and that is configured and arranged for communication with the atmosphere. Finally, the cleaning element includes an outlet port in communication with the chamber and the sample cell.
