ultrasonification for 100l scale

The ultrasonic processing reactor or ultrasonification for 100l scale is primarily applied in pilot-scale amplification and industrial production across fields such as chemical engineering, pharmaceuticals, food, and biological extraction. Its core function is to achieve efficient dispersion, extraction, reaction, or homogenization of materials through the cavitation effect of ultrasonic waves.

Working principle: Industrial amplification application of cavitation effect
The core of a 100L ultrasonic reactor or ultrasonification for 100l scale is the ultrasonic cavitation effect, which converts sound energy into mechanical energy through high-frequency vibration, driving the "generation expansion collapse" cycle of liquid microbubbles, creating an extreme physical and chemical environment, and promoting the reaction process
Cavitation bubble collapse: Ultrasonic waves at 20-40kHz form micrometer sized bubbles in liquid. When the bubbles collapse instantly, local high temperatures (5000K+), high pressures (1000atm+), and strong shear forces are generated, breaking down the activation energy barrier of the reaction and accelerating molecular collisions and bond breaking/recombination.
Micro jet and mixing enhancement: The micro jet generated by bubble collapse (with a velocity of up to 200m/s) impacts the reaction system, achieving molecular level mixing and eliminating mass/heat transfer limitations, especially suitable for high viscosity, multiphase (liquid-liquid/liquid-solid) reaction systems.
Free radical generation: The cavitation process breaks down water molecules/solvent molecules, producing a large number of hydroxyl radicals (· OH) and hydrogen radicals (· H) that participate in oxidation, degradation, polymerization, and other reactions, enhancing reaction selectivity.

Core structure: Suitable for industrial design of 100L scale
The ultrasonification for 100l scale is an integrated device consisting of a reaction vessel, an ultrasonic generation system, and an auxiliary control unit. Its core structure is as follows:

-Sealing: Dual mechanical seal+PTFE gasket, suitable for a working pressure of 20 bar, to prevent medium leakage.
2. Ultrasonic generator system: 1-3kW power (suitable for 100L scale), frequency 20-40kHz (low-frequency strong cavitation) or 40-80kHz (high-frequency fine dispersion);
-Transducer: made of titanium alloy/lead zirconate titanate (PZT) material, embedded in the bottom or side wall of the tank, converting electrical energy into mechanical vibration (adjustable amplitude of 0.1-100 μ m);
