Supply of mobile centrifugal aerators

Floating mobile centrifugal aeratorUnlike surface aerators and bottom aeration systems in water tanks, it not only has the ability to push flow in a circular direction, but also has the function of dissolved oxygen in depth; It can stir and oxygenate water bodies and sludge in deep waters, significantly enhancing the biological treatment capacity.

Floating mobile centrifugal aeratorworking principle

On the basis of the original NQXB, single-sided intake has been changed to double-sided or center intake, and a floating ring (made of stainless steel or fiberglass) has been added to the upper part of the intake pipe. The floating ring, intake pipe, and aerator are connected as a whole. As shown in the figure, the floating ring relies on the buoyancy of water to suspend the aerator in the water. The floating ring is pulled by three steel wire ropes, and the other end of the steel wire rope is fixed to the edge of the pool or fixed with three anchor points in the pond. During installation, place the aerator and floating ring into the water as a whole, and drag them to the designated area with steel wire ropes. Then fix the other end of the three steel wire ropes in three different directions at the edge of the pond. For ponds with larger water surfaces, three anchor points can be set up for positioning. During maintenance, simply untie the steel wire rope fixed at the edge of the pool, pull the equipment back to the edge of the pool and lift it out of the water.

The upper end of the intake pipe is the air intake port, located above the water surface, and the lower end is connected to the mixing chamber. After the power is turned on, due to the rotation of the impeller, high-speed water flows out from the impeller outlet, forming negative pressure through the mixing chamber. Therefore, air is sucked in and mixed with sewage, and the mixed liquid flows out from the outlet, completing the oxygenation of the sewage.

Technical features:

1. The Revolution of Inflatable and Blended Mixing Technology

The FPQ aerator mixer is an addition of a stirring device to the original aerator, which significantly improves the oxygenation capacity and performance of the equipment.

2. High performance composite impeller

The hydraulic performance of the composite impeller is designed using computers and simulated working conditions. The entire impeller is cast in one go and has a relatively stable blade shape. Through dynamic balance testing, the efficient performance and smooth operation of the composite impeller are ensured.

3. The unity of nitrification and denitrification

During the nitrification process, the blower and motor are simultaneously turned on, and the airflow and thrust direction are *. The shearing impeller cuts into small bubbles, which are carried by the strong water flow generated by the mixing impeller, and the nitrification process is completed under the action of aerobic organisms.

In denitrification, only the motor is turned on and no air is injected into the water. The denitrification process is completed under the action of anaerobic and facultative microorganisms. Nitrification and denitrification are integrated, which is the organic unity of aeration machinery and stirring machinery.
