Ultrasound-assisted transesterification reactions for biodies

Ultrasound-assisted transesterification reactions for biodiesel production
Application of Ultrasound Vibrating Bar in Scale Prevention
We take heat exchanger as an example. Ultrasound vibrating rod is usually installed at the inlet of heat exchanger. Flange connection and control valve are used to control the vibration rod. It can stop the production of ultrasonic equipment in maintenance and maintenance. The main principle is that in the process of ultrasonic transmission, due to resonance transmission and energy generation, the molecule of scale, water and metal heat exchanger obtains energy in the process of vibration, while the water in the heat exchanger tube generates vibration and intense collision while obtaining energy, which makes the unstable water molecule containing various inorganic salts produce innumerable. Cavitation bubbles (cavitation) form cavitation chambers for water molecules. When these bubbles expand rapidly and close suddenly, they produce a local impact of thousands of atmospheric pressure, a high-speed jet with a velocity of 400 km/h and a high energy of more than 5000 K. These energies destroy the combination of positive and negative ions with acid radicals, destroy the conditions for scale formation, and thus achieve scale prevention.
