Impeller aerator

Working principle of 1.5KW impeller aerator


The main performance indicators of the aerator are defined as aeration capacity and power efficiency. Aeration capacity refers to the amount of oxygen added by an aerator to the water body per hour, in kilograms per hour; power efficiency refers to the amount of oxygen added to a water consumed by one aerator, in kilograms per kilowatt-hour. . For example, a 1.5 kW waterwheel aerator has a power efficiency of 1.7 kg / kWh, which means that the machine consumes 1 kWh of electricity and can add 1.7 kg of oxygen to the water body.


Although aerators are used more and more widely in aquaculture production, some fisheries practitioners still do not understand its working principle, types and functions, and they appear blind and arbitrary in actual operation. It is necessary to understand how it works first, so that you can master its use in practice. As we all know, the purpose of using an aerator is to increase dissolved oxygen to the water body, which involves the solubility and dissolution rate of oxygen. Solubility includes three factors: water temperature, water salt content, and oxygen partial pressure; dissolution rate includes three factors: the degree of unsaturation of dissolved oxygen, the contact area and mode of water-gas, and the state of water movement. Among them, the water temperature and the salt content of water are a stable state of the water body, and generally cannot be changed. The degree of unsaturation of dissolved oxygen is a factor we want to change, and it is also a current state of the water body. Therefore, in order to increase oxygen to water, three factors, such as the partial pressure of oxygen, the contact area and method of water-gas, and the state of water movement, must be changed directly or indirectly. In response to this situation, the measures taken when designing the aerator are:


1) Agitate the water body with mechanical parts to promote convection exchange and interface update;


2) Disperse the water into fine mist droplets and spray it into the gas phase to increase the contact area of water and gas;


3) Inhale through negative pressure to disperse the gas into micro-bubbles and press it into water.


Various types of aerators are designed and manufactured based on these principles, and they either take one measure to promote the dissolution of oxygen, or take two or more measures.
