There are many types of aerators in China, and impeller aerators are the most used in pond aquaculture. This is because impeller-type aerators have many functions such as water abatement, aeration, mixing, and aeration, and are more suitable for the regulation of water quality requirements in still-water ponds. The oxygenation efficiency is also relatively high.
Various types of impeller-type aerators have different shapes and sizes, but they basically consist of motors, speed reducers, support frames, impellers, and buoys. The impeller-type aerator has the functions of water stirring, aeration, mixing, aeration, etc. These functions are all completed at the same time during the operation of the machine. After starting up, the impeller sucks up the oxygen-depleted water in its lower part and pushes it out again to make the standing water become living water. The water under the impeller is strongly stirred by the blades and the agitating pipe, stimulating the waves on the water surface to form a curtain of water that can be wrapped in air. This not only enlarges the contact surface area at the air-liquid interface, but also thins the double membrane between gas and liquid. , And constantly updated to speed up the dissolution rate of dissolved oxygen in the air. When stirring, the harmful gases (such as hydrogen sulfide, ammonia, methane, sulfur dioxide, etc.) in the water are also desorbed from the water by aeration and discharged into the air. Because the impeller rotates during the process, a negative pressure is formed at the rear of the water mixing pipe, so that air can be sucked into the water through the water pipe, and is immediately stirred into micro-bubbles to enter the pressure zone of the impeller. Therefore, it is also beneficial to speed up the dissolution of oxygen in the air. Improve oxygenation efficiency. As the lower water is constantly being raised and mixed with the surface water, the surface water is continuously updated, and the original surface water is continuously supplemented by gravity. This function of the impeller aerator is excellent because it not only helps to break the vertical uniformity of dissolved oxygen in the pool water, but also gives full play to the oxygenation effect of pond aquatic organisms.
