Air-water mixed Jet Aerator diffuser

Product Details

MainStructure

Air-water mixed jet aerator diffuser is mainly composed of seven parts: outer cavity, inner cavity, mixing cavity, outer nozzle, inner nozzle, air inlet and liquid inlet. Both the inner and outer cavities are cavities formed by butting and bonding the upper and lower butterfly shells.

The inner and outer cavities are coaxially sleeved, and the liquid inlet and the air inlet are respectively connected to the inner cavity and the outer cavity along the axial direction.

The inner and outer nozzles are arranged concentrically and uniformly along the circumference of the inner and outer cavity respectively.

The inner cavity is the working medium cavity, the outer cavity is the ejection medium suction cavity, and the inner and outer nozzles are the mixing cavity. The aerator itself does not contain any electromechanical components and transmission components.

The necessary equipment when working is: jet circulation pump and blower.

Material

As a reinforced resin composite material, FRP material has superior anti-corrosion performance, strong plasticity, easy molding. It can be manufactured by hand, easy to make the small batch production, anti-aging, and long service life. It is an important direction in the research field of new materials.

The main material of Air-water mixed jet aerator diffuser is the 189 resin (boat resin) glass fiber reinforced plastic.

Working principle

Aeration and oxygenation

Oxygen in the nozzle

Oxygenation in the horizontal jet zone

Oxygenation in the vertical lifting zone

Oxygenation in secondary turbulent zone

Main technical performance

The technical performance of air-water mixed jet aerator is as follows:

●Working air volume: 800~1200m3/h;

●Oxygen utilization rate: 22.0~28.2%;

●Power efficiency: 4.17~5.36kgO2/KW•h;

●Service life:≥25 years

●Circulating water volume: 420~480m3/h

●Oxygenation capacity: 76.5~89.6kgO2/h

●Service area: 70~90m2; 256m2 (urban sewage)

Installation requirements

In order to easy to install and repair, the Air-water mixed jet aerator adopts an automatic coupling installation method. The installation height of the aerator is 800~1000mm, and the installation is for the nozzle center level.

When the aerator is permanently installed, it must be ensured that the horizontal error of the center of the outer nozzle does not exceed ±1mm.

During the automatic-coupling installation of the aerator, in addition to ensuring that the horizontal error of the outer nozzle center does not exceed ±1mm, it should also ensure that the concentricity error on the automatic -coupling base does not exceed 1mm.
