Invention Reference Number
A novel ultrasonic cleaning technology offers a non-invasive method to remove particulate buildup from internal surfaces of metal ducts and enclosures. Designed for environments where traditional methods are impractical, this approach enables safer and more efficient maintenance of contaminated or inaccessible systems. The technology minimizes personnel exposure and avoids secondary contamination, supporting improved safety and operational efficiency in nuclear and industrial settings.
Description
This innovation utilizes high-power ultrasonic actuators attached externally to metal structures to induce vibrations that dislodge internal surface deposits. Operating at ultrasonic frequencies, the system delivers energy through structural walls, eliminating the need for mechanical entry or chemical use. This method effectively removes particulate accumulation – including hazardous or radioactive residues – without disrupting operations. Testing has demonstrated significant particle removal from stainless steel ducts and other components under representative conditions. The system is compatible with curved and flat surfaces and can be adapted to a range of geometries. Its externally mounted configuration allows integration into remote or automated cleaning systems, making it particularly suitable for high-radiation, high-contamination, or otherwise hazardous environments.
