Abstract
A high pressure cleaner comprises a cleaning device (10) and an effluent recovery device (12). The cleaning device (10) is mainly constituted by a cleaning head (20) having a central chamber (44) into which a nozzle (26) sprays a high pressure cleaning liquid, the effluents being recovered in a peripheral chamber (46) connected to a decanter (54) of the recovery device (12). The actual decanter (54) is connected to an exhauster (72) across a liquid-gas separator (60) and filters (70). The liquid phase of the effluents is periodically recovered by a tube (80) immersed in the decanter (54) and connected to a hydroejector (82). The solid phase of the effluents is held back by a filter (92) surrounding the tube (80).
