Product Description
Rotary mixing coarse bubble aerator is a device for oxygenated
aeration in the form of multi-layer spiral cutting. When the
airflow enters the aerator, it first passes through the two spiral
cutting system and enters the lower multilayer zigzag aeration head
for multi-layer. Cutting makes the bubbles into micro bubbles,
which greatly improves the utilization rate of oxygen, and has the
characteristics of uniform aeration and high oxygenation
efficiency.
Working Principle
After the gas enters the aerator, it begins to rotate and split to
make the gas and liquid mix evenly, forming a continuous gas-liquid
enhanced swirl area. After three times of continuous cutting in the
gas-liquid mixing area, the bubble will start to spread evenly
under the impact of continuous air supply, which will drive the
mixture to rise together, float to the umbrella and carry out
multi-layer shearing and cutting again, so that the bubbles will be
smaller, so as to maintain the uniform and stable operation of the
bubbles for a long time, objectively increasing the contact area of
the gas-liquid, which is conducive to the dispersion of oxygen,
more The contact surface of oxygen and the utilization rate of
oxygen are improved.
Product Advantage
1. Simple structure and easy to install and maintain.
2. High oxygen utilization, stable performance.
3. The air holes are not easy to be blocked, and the sewage is not easy to pour backward.
4. Circular force, uniform force and long service life.
5. The system is inexpensive.
Product Application
It is applicable to the biochemical treatment of industrial
wastewater and urban domestic sewage by activated sludge process,
the aeration device of biological contact oxidation process sewage
treatment and the pre aeration of regulating tank, and widely
applicable to the push flow and mixed aeration tanks of biochemical
treatment.
Package Method
18pcs per master carton.
