The principle of using oxygen concentrators in the aquaculture industry mainly includes the following aspects:
Working principle of oxygen concentrator
Aquaculture oxygen concentrators mainly use air separation technology to separate oxygen from the air and inject it into aquaculture water to increase the oxygen content in the water. The specific process is as follows:
Air compression: The oxygen generator compresses air into a high-pressure state through a compressor.
Cooling liquefaction: The condenser cools the compressed air into a liquid state, separating moisture and oxygen from the air.
Oxygen separation: The evaporator heats the cooled air again to separate oxygen from the liquid state. Finally, the oxygen separator separates oxygen from its gaseous state and injects it into the aquaculture water.
Application scenarios and advantages of oxygen concentrators
Oxygen concentrators are suitable for various aquaculture farms, household fish ponds, ornamental fish farms, and other places. Its advantages include:
High efficiency: able to provide sufficient oxygen for aquatic organisms in a short period of time, promoting growth and health.
Energy saving and environmental protection: By using efficient compressors and turbines, energy consumption is reduced and no pollution is generated during operation.
High purity oxygen: The oxygen produced by the oxygen concentrator has high purity, which helps to improve the growth rate and survival rate of aquatic organisms.
Intelligent control: Some oxygen concentrators are equipped with intelligent control systems that can automatically adjust the amount of oxygen produced based on real-time monitoring data of water quality, ensuring that the water is rich in sufficient oxygen.
Principle and advantages and disadvantages of aerator
The aerator mainly increases the oxygen content in water through physical and biological functions. Its working principle includes:
Physical agitation: By stirring the water with an impeller, the contact area between the water and air is increased, thereby improving the rate of oxygen dissolution.
Biological function: The aerator can eliminate harmful gases in water, improve water quality conditions, and promote water convection and exchange.
The advantages of an aerator include:
Lifting and stirring: Enhance the alternation between bottom water and surface water, and increase the dissolved oxygen content of bottom water.
Exposure to harmful gases: It can effectively expose harmful gases such as ammonia, hydrogen sulfide, etc. in water bodies.
Disadvantages include:
Dependent on electricity: must be used under electrified conditions, not suitable for remote areas.
Limited oxygenation range: The oxygenation area is limited to a certain range and is suitable for smaller water bodies
