Hybrid Submersible Mixing Aerator
product picture
Features
1. Unique mixing chamber design, with large amount of inhaled air, good mixing effect, high oxygen utilization rate, large service area and good aeration effect.
2. The air-water mixture is discharged from the air mixing chamber at a special angle, which can make the water flow spiral to the horizontal direction and then move upward. It has a stirring effect while aeration, and can effectively prevent the settlement of suspended solids.
3. The machine body sinks into the water and operates without noise. A silencer can be added to the outlet surface of the air intake pipe to enhance the silencer effect.
4. Simple and compact structure, high-quality mechanical seal, long-term operation without trouble.
5. Relying on self-weight positioning and integrated hoisting design, it is easy to install and flexible in layout. It can achieve rapid hoisting without the need for drainage and without interrupting process operation.
Working Principle
The impeller of this equipment is directly connected to the main shaft of the motor, and the motor drives the impeller to rotate. The pressurized air supplied by the blower is sent to the impeller through the movable air duct. It is crushed into tiny bubbles under the high speed of the impeller. The bubbles and the surrounding water are strongly mixed and radiate in a wave-shaped curve under the action of the rotor. The stator channel can ensure that the water-gas mixture is evenly distributed in the aeration tanks with different shapes and structures. At the same time, the strong floc flow generated by the rotor ensures the ideal oxygen transfer effect and continuously promotes the mixing of water, air and activated sludge in the tank. Biochemical effect, thereby achieving rapid decontamination effect. Due to the high-speed rotation of the impeller, centrifugal force is generated. Under the action of centrifugal force, a negative pressure is formed around the impeller, thereby generating self-suction force. This reduces the equipment's air supply pressure requirements for the blower, which can usually be equal to the water depth, significantly reducing power consumption compared to traditional equipment.
The submersible aerator is mainly composed of a reduction motor, air inlet, air duct, base assembly, conical impeller, air supply system, electronic control system, etc.
Technical Data
The hybrid mixing aerator is suitable for industrial wastewater treatment with various pollution loads and aerobic aeration engineering design applications. It can function in a water depth range of 4 meters to 20 meters. The motor power is 5.5-22KW. The cover shell is made of stainless steel. in petrochemical wastewater treatment, some special materials are usually selected.
