Abstract
In order to clean a surface (A) located in a hostile medium, use is made of a bush hammer (34) mounted on a remotely controlled vehicle (32). The waste produced by the bush hammer (34) is directly collected by a collecting pipe (12) connected to an exhauster (14). Cyclone separators (22, 24), an electostatic filter (26) and absolute filters (28, 30) arranged in this order on the collecting pipe recover the waste in decreasing size order. The cyclone separators are mounted on two compartments (76, 78) formed in a vessel (80) and each equipped with devices (90, 92, 100, 102, 106, 108) making it possible to inject into the compartments a waste treatment product and to recover the same after filtering. A container (120) is also placed beneath the electrostatic filter (26).
