The impeller type aerator is a common aerator that can meet the supply needs of large-area ponds. The depth of oxygen supply can reach 6 meters. It has the functions of increasing oxygen, lifting water, exposing harmful gases, and enhancing water efficiency. . The impeller aerator uses a mechanical method to increase oxygen. The motor drives the water surface impeller to rotate to stir the water surface, thereby increasing the contact area between gas and liquid to achieve the purpose of dissolved oxygen. Next, let’s take a look at the working principle of the impeller aerator with the editor.
The impeller aerator is mainly composed of a motor, a reduction box, a water surface impeller and a float. It uses mechanical methods to increase oxygen. The motor drives the water surface impeller to rotate to stir the water surface, stir the air film and liquid film, and increase the contact between air and liquid. area to expand the concentration gradient of oxygen in water and increase the speed of oxygen transfer and diffusion from air to water.
After the impeller-type aerator is turned on, the impeller sucks up the oxygen-depleted water in the lower part of it, and then pushes it out to the surroundings, turning the stagnant water into living water. The water under the impeller is strongly stirred by the blades and tubes, causing water jumps and waves on the water surface to form a water curtain that can envelop the air. This not only expands the surface area of the gas-liquid interface, but also thins the double membrane between the gas and liquid. And it is constantly updated to promote the dissolution rate of oxygen in the air.
1. Oxygenation
The impeller-type aerator has large power and high efficiency, and can increase oxygen up to more than 1800 grams per kilowatt/hour. When the pool water is enriched with oxygen, it can effectively inhibit the occurrence of bacterial and viral diseases in aquaculture, which is of great significance to increasing aquaculture production and income.
2. Lift water
The impeller-type aerator can lift the bottom water so that it alternates with the surface water, thereby adding oxygen to the lower water. Its oxygenation depth exceeds 2 meters, which is beneficial to breaking the vertical uniformity of dissolved oxygen in the pool water. It can give full play to the oxygenation effect, so it is suitable for high-yield deep-water fish ponds.
3. Exposure to harmful gases
The impeller aerator has a strong aeration function and can effectively remove harmful gases such as ammonia, hydrogen sulfide, methane, carbon monoxide, etc. in the pool water.
4. Water efficiency enhancement
The impeller aerator can also increase the efficiency of freshwater aquaculture water bodies, thereby improving the quality of the aquaculture water bodies. It can quickly relieve the anoxic floating heads of fish and shrimps, break the stratification of the pond water, increase the primary productivity of the pond, increase the breeding density, increase the yield, and reduce the feed cost. coefficient.
