1、 Introduction:
A diffuser aerator is a tool used to increase the oxygen content in wastewater during water treatment processes.
The diffuser consists of a toothed aerator head, a toothed perforated diffuser cover, a guide plate, an intake pipe, and a locking nut.
Fiberglass or ABS integral forming, with good corrosion resistance. The serrated diffuser cover is of the inverted umbrella type, with an aeration hole at the center of the umbrella shape, which plays a role in replenishing air and evenly distributing the entire diffuser cover, reducing energy consumption, and evenly dividing the water and gas mixture, reducing the requirement for installation levelness of the aerator. There are downward sloping serrations around the diffuser cover to further cut the bubbles. Air enters from the top and is repeatedly cut to improve oxygen utilization efficiency.
2、 Characteristics:
1. The intense mixing of liquids causes gas to be transported from pipelines to aerators, where it passes throughÆ The inner hole of 25 is cut for the first time as water vapor through a serrated aeration head. After passing through the diffuser and being re cut by the surrounding serrations, it drives the surrounding stationary water to rise. Due to the energy difference, it causes severe mixing of gas-liquid. In addition, due to the distribution of the aerator at the bottom of the pool, the rising bottom bubbles and the falling water flow undergo convection after aeration, which increases the mixing of gas-liquid and accelerates the renewal of the water film at the gas-liquid interface.
2. After two sawtooth cuts and gas-liquid mixing, the diameter of the bubbles decreases, thereby increasing the gas-liquid contact area and facilitating oxygen transfer.
3. The diffusion effect of the diffuser hood causes it to diffuse several bundles of gases into a cylindrical shape, changing the gas distribution state at the bottom of the pool, increasing the gas distribution area, and intensifying the diffusion of bottom bubbles and the mixing of gas-liquid at the bottom, which is more conducive to aeration and oxygenation.
