Dual-use oxygen concentrator from water purifier
GS PAPER III: Science and Technology- developments and their applications and effects in everyday life.
Context: Students of Lords Institute of Engineering & Technology (Autonomous) have developed a dual-use oxygen concentrator from water purifier.
- The final product will cost ₹20,000 with the purifier converted into a full time oxygen concentrator.
How does it work?
- Air is taken from atmosphere, compressed and allowed to pass through silica gel that reduces unwanted rise in temperature apart from removing moisture content.
- This low temperature and moisture-free air is passed through Zeolite (13X) pellets where nitrogen is blocked and oxygen is allowed.
- By blocking nitrogen through these pellets, 85-92% of pure oxygen can be obtained.
- The oxygen is allowed to stay for a calculated moment of time for better flow and then allowed to pass through water by using a humidifier as dry oxygen causes throat issues.
- The flow of oxygen is regulated through a regulator installed at the exit point of concentrator.
- Two exit nozzle points are created so that two patients can use it at a time.
