Off gas film cooler cleaner

PDF Version Also Available for Download.

Description

An apparatus is described for cleaning depositions of particulate matter from the inside of tubular piping while the piping is in use. The apparatus is remotely controlled in order to operate in hazardous environments. A housing containing brush and shaft assemblies is mounted on top of the tubular piping. Pneumatic cylinders provide linear motion. A roller nut bearing provides rotary motion. The combined motion causes the brush assembly to rotate as it travels along the tube dislodging particulate matter. The main application for this invention is to clean the off gas cooler of a radioactive waste vitrification unit.
