Cleaning system for heat exchanger tube inner surfaces
The patent US12011805B2 describes a sophisticated cleaning system designed for the inner surfaces of tubes in heat exchangers. The system comprises two primary cleaning devices, each equipped with cleaning heads that facilitate the supply of cleaning fluid and blasting media into the tubes during a cleaning cycle. This process is part of a closed-loop flow path that includes a reclaimer, which collects and separates debris from the blasting media for disposal, while allowing the reclaimed media to be reused in the cleaning process. A controller plays a crucial role in this system by determining delivery parameters based on specific characteristics of the tubes, such as material composition, diameter, and wall thickness, ensuring an efficient and tailored cleaning operation.
Additionally, the system features motorized tools that can move along the tubesheets, allowing for the cleaning of multiple tubes simultaneously or sequentially. The cleaning fluid often includes pressurized gas, and the system is designed to establish a fluid-tight seal between the cleaning heads and the tubes to optimize the cleaning cycle. The controller is also responsible for adjusting parameters like pressure and flow rate based on the tool's position relative to the tubesheet, enhancing the precision of the cleaning process. Overall, this innovative cleaning system aims to improve the maintenance and efficiency of heat exchangers by providing a reliable method for cleaning tube interiors.
