How to use public space aerator accessories correctly is a problem that users are paying more and more attention to. When to open public space aerator accessories? It is recommended that users turn on the phone in the afternoon when it is sunny; turn it on the next morning when it is cloudy; turn it on in the middle of the night when the rain is continuous; remind the user not to turn on the device after sunrise in the morning; not to turn on in the evening; not to turn on during the day on cloudy and rainy days.
The main performance indicators of the aerator accessories in public spaces are specified as aeration capacity and power efficiency. The aeration capacity refers to the amount of oxygen that a public space aerator accessory adds to the water per hour, in kilograms/Hours; power efficiency refers to the consumption of an aerator1The oxygen increase of water in kilowatt-hours, in kilograms/Kilowatt hours. Such as1.5Kilowatt waterwheel aerator, power efficiency is1.7kg/KWh, which means the machine consumes1KWh can increase to the water body1.7Kilograms of oxygen.
Although the accessories of space aerators in public places are more and more widely used in aquaculture production, some fishery practitioners still do not understand its working principle, type and function, and they are blind and random 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 public space aerator accessories is to add dissolved oxygen to the water body, which involves the solubility and dissolution rate of oxygen. Solubility includes water temperature, water salt content, oxygen partial pressure3Factors; the dissolution rate includes the degree of unsaturation of dissolved oxygen, the contact area and method of water and air, and the movement of water3Factors. Among them, the water temperature and the salt content of the water are a kind of stable state of the water body, and generally cannot be changed. The degree of unsaturation of dissolved oxygen is the factor that we want to change, and it is also a current state of the water body. Therefore, in order to increase oxygen to the water body, it is necessary to directly or indirectly change the oxygen partial pressure, the contact area and method of water and air, and the movement of water.3Factors.
In view of this situation, the measures taken when designing the aerator include:
1) Use public space aerator accessories to stir the water body to promote convection exchange and interface update;
2) Disperse water into fine mist droplets and spray them into the gas phase to increase the contact area of water and gas;
3) Inhale through negative pressure to disperse the gas into microbubbles and press them into the water.
Various types of public space aerator accessories are designed and manufactured according to these principles. They either take one measure to promote oxygen dissolution, or take two or more measures.
