Abstract
A wiper assembly is provided for cleaning the reactor tubes of an ultraviolet-light reactor. The wiper assembly is positioned inside a reactor chamber of the ultraviolet-light reactor. The wiper assembly includes a wiper that has a circular opening sufficiently large to accommodate a reactor tube. A wiper blade is formed on the wiper circumferential of the opening and being deflected such that when the reactor tube is positioned through the opening, the blade engages the outer surface of the reactor tube. The wiper is formed of a plastic material. The wiper is connected to a platform positioned within the reactor chamber. The platform supports the wiper in the reactor chamber such that the reactor tube extends through the opening in the wiper. According to one aspect of the invention, at least one rod is connected to the platform. The rod extends out of the reactor chamber. The rod can be moved from outside the reactor chamber for mechanically reciprocating the platform along the length of the reactor tube in the chamber, whereby, the wiper blade slides along the outer surface of the reactor tube to wipe off at least some of the fouling that may have accumulated on the outer surfac…
