MAH ^Ⓡ(MAH-25, 10 (upwards/downwards))

This product is the oscillation element of the MU Green Reactor and MU Aerator,and has the bubble generation function and strong circulation flow function of the oscillation element.

Refinement of gases (What is an Oscillation Element?)

MU Oscillator is a static mixing device with gas swirling and shearing functions that generate strong spiral. It is attached to the gas injection part and is injected into the liquid from the bottom to the top at high speed (10 m/s or more). Inside the Oscillator, you will see two twisted wings with void at the center in the axis direction.

Two different flows making vibration

Pressurized gas emitted from the injection section at high speed can be divided into two flows in MU Oscillator, like MU Mixer. These are the flow spirals along the wings and the flow going straight through the hole at the center in the axis direction. Oscillation occurs due to two different speeds of the swirling flow and the straight flow.

What is the oscillation phenomenon?

In a word, this oscillation phenomenon is the vibration of gas. This vibration has an effect of accelerating the refinement of gas, and is specifically caused by the following four phenomena.

1. Turbulent vortices are generated and collapsed by high speed jet of pressurized gas into liquid.
2. Since pressurized gas becomes in a state of self-excited vibration, a phenomenon in which an external force that causes vibration increases the vibration width or the vibration continues due to the vibration itself, sound waves of 200-1000 Hz are generated.
3. The pressurized gas is jetted into liquid from the jetting part, and cavitation is generated by pressure drop accompanying the jet.
4. The pressurized gas is divided into a flow which goes straight through the center part of the oscillation element and a flow which turns along the wing body, and shearing force is generated from the difference between the two speeds.
