Description

Diffuser structure

The invention relates to a diffuser, in particular to a diffuser structure that can destroy bubbles to increase the dissolved oxygen rate in water and has a non-reversal function.

The diffuser is a kind of diffuser to increase the amount of dissolved oxygen in the water to provide the oxygen required by the 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 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 diffuses the air, when the air flow is stopped, the wastewater and sludge in the water will easily flow back and cause the pipeline to be blocked.

In addition, in the process of gas dispersing, 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, causing damage or the situation that the diffuser is lifted and detached as a whole.
