Uniform and dense underwater centrifugal aerator QXB3.0 Keppel

Uniform and dense underwater centrifugal aerator QXB3.0 Keppel

The QXB3.0 biochemical anoxic tank disc centrifugal aerator has effective water circulation due to water jet *, which cuts the air into a large number of tiny bubbles. Greatly increasing its surface area, and due to the slow rise of bubbles, a large amount of oxygen in the air dissolves in water, making the power efficiency of this machine superior to other types of aerators.

Purpose:Uniform and dense underwater centrifugal aerator QXB3.0 Keppel

The QXB3.0 submerged centrifugal aerator is used for aeration tanks, aeration sedimentation tanks, pre aeration tanks, aerobic nitrification tanks, aeration and oxygenation mixing in various biochemical treatment processes of sewage treatment projects, as well as oxygenation in aquaculture ponds.

Construction and working process

The QXB3.0 submerged centrifugal aerator consists of a submersible sewage pump, a mixing chamber, a base, an intake pipe, and a muffler. The upper end of the intake pipe is the air suction 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 through the mixing chamber, forming negative pressure. Therefore, air is sucked in and mixed with liquid, and the mixed liquid flows out from the peripheral outlet, completing the oxygenation of the liquid.

principle

The QXB3.0 submerged centrifugal aerator is directly driven by a motor and an impeller. The centrifugal force generated by the rotation of the impeller is used to discharge the surrounding water and form a low-pressure zone for sucking in water flow. At the same time, a vacuum is created at the inlet of the impeller to suck in air. In the mixing chamber, air and water are fully mixed to form a uniform air-water mixture, which is quickly discharged under the action of centrifugal force. Due to the water jet *, effective water circulation is created, causing the air to be sheared into a large number of tiny bubbles. Greatly increasing its surface area, and due to the slow rise of bubbles, a large amount of oxygen in the air dissolves in water, making the power efficiency of this machine superior to other types of aerators.

feature

1. Advantageous mixing chamber design, high intake air volume, good mixing effect, and high oxygen utilization rate;

2. The air-water mixture is discharged from the mixing chamber at a special angle, which can make the water flow in a spiral shape towards the horizontal direction and then upwards, while also having a stirring effect during aeration;

3. The body sinks into the water and runs without noise. The water outlet of the intake pipe can be equipped with a xiao sound sensor to enhance the noise reduction effect.
