In aquaculture production, aerator suppliers are using more and more widely, but some fishermen do not understand its working principle at present, in actual operation, it is blind and arbitrary. Therefore, we must first understand its working principle in order to grasp its usage in practice.
The purpose of the aerator supplier is to add dissolved oxygen to the water. This involves two aspects of oxygen solubility and dissolution rate. The former includes three factors: water temperature, water salinity and oxygen partial pressure. The latter includes three factors: the degree of unsaturation of dissolved oxygen, the contact area and method of water vapor, and the state of water movement.
A stable state of water in which the water temperature and the salt content of the water. Therefore, in order to increase oxygen to the water body, it is necessary to directly or indirectly change the three factors of oxygen partial pressure, water-gas contact area and method, and water movement status. For this kind of situation, certain measures need to be taken when designing. Let's take a look at it together!
1. The aerator supplier uses mechanical parts to stir the water to promote flow exchange and interface update.
2. Disperse the water into fine mist droplets and spray the gas phase to increase the contact area of water vapor.
3. Inhale under negative pressure, disperse the gas into micro-bubbles, and then press it into the water.
Suppliers of various types of aerators are designed and manufactured based on these principles. They either take one measure to promote oxygen dissolution, or take two or more measures.
