Description

Diffuser structure

This creation is about a diffuser, especially a diffuser structure that can destroy bubbles to increase the dissolved oxygen rate in the water and has a non-reversal function.

The air diffuser is a kind of diffuser, which is used to increase the amount of dissolved oxygen in the water to provide the oxygen required by aquatic organisms. It is widely used in sewage, wastewater treatment systems or aquaculture ponds.

The general diffuser is mostly set at the bottom of the pool or sink. After the air is pressurized into the air pipeline by a blower, the air then passes through the diffuser to form bubbles into the water. With the structure of the diffuser, the airflow diffuses to increase the air outlet area, and the airflow passes through the micropores and then enters the water, which can generate finer bubbles to increase the dissolved oxygen rate.

However, before and after the diffuser, when the air flow is stopped, the wastewater and sludge in the water will easily flow back and cause pipeline blockage.

In addition, in the process of gas dispersal, the gas tends to concentrate on the central part of the diffuser, so that the pressure at the center of the diffuser is too high, which may cause damage or the situation that the diffuser is lifted and detached as a whole.

The main purpose of this creation is to provide a diffuser structure with a non-reversal function.
