The working principle of the oxygen concentrator - converting air into oxygen
The oxygen concentrator is a medical device that helps people with low oxygen levels in their blood. They are powered by plugging the device into an electrical outlet or using a battery. If a battery is used, it needs to be plugged into an electrical outlet for charging. Most concentrators also come with an adapter so you can use the device while driving.
The oxygen concentrator compresses the air, purifies it, and then extracts pure oxygen. Air is composed of 80% nitrogen and 20% oxygen. The oxygen concentrator separates nitrogen from the air and provides patients with a high dose of oxygen. It is difficult for us to obtain a certain percentage of oxygen without the help of medical equipment.
The working principle of the oxygen concentrator - converting air into oxygen
First, let's break down the components of the oxygen concentrator, as shown in the figure:
The components that make up the oxygen concentrator are as follows:
Primary and secondary filters: The filters have the ability to filter out impurities in the air
Air compressor: It helps push indoor air into the machine and push it into the molecular sieve bed.
Filter: The filter helps filter out impurities in the air.
Molecular sieve: These sieves have the ability to capture nitrogen.
Switching valve: These valves help switch the compressed air flow between the molecular sieve towers.
Flowmeter: Helps set the flow rate per minute, in liters.
The oxygen concentrator filters the air through a filter. In terms of filter design, domestic oxygen concentrators are mostly designed with 1 or 2-stage filtration systems. Some imported oxygen concentrators can reach a 3-stage filtration system, and a few higher-quality imported oxygen concentrators can reach a 4-stage filtration. Clean air can be obtained through filtration.
Next, the oxygen concentrator uses the adsorption performance of the molecular sieve. Through physical principles and powered by an oil-free compressor, nitrogen and oxygen in the air are separated to finally obtain highly concentrated oxygen.
Using zeolite molecular sieves as adsorbents, oxygen is adsorbed and released from the air using the principle of pressure adsorption and pressure reduction desorption to separate oxygen.
Through the figure, you can see two integrated molecular sieve tanks with an oxygen storage tank in the middle. When this molecular sieve tank is pressurized, 78% of the nitrogen in the air will be adsorbed, and then the separated oxygen enters this oxygen storage tank. When the pressure inside the molecular sieve tank reaches a certain value, the solenoid valve will control the air to enter another molecular sieve tank, then adsorb the nitrogen in the air, and the separated oxygen enters the oxygen storage tank. This is a process of alternating pressurization and oxygen production of the two molecular sieve tanks, constantly storing oxygen in the oxygen storage tank.
Finally, the pipeline of the oxygen storage tank will be linked to the flowmeter and adjusted to the corresponding flow concentration we adapt to. The highly concentrated oxygen will enter our oxygen tube through the oxygen outlet. There will also be a humidification bottle connected to the oxygen outlet. This water bottle is used to humidify overly dry oxygen.
