Stationary cleaning device for cleaning cooling surface of e.g. air condensation system for condensing excess steam from turbine system in chemical industry, has tubing moved from nozzle fitting into shaft and directly contacting shaft wall

摘要

The device has a tubing (6) guided in a region of the device and moved in a shaft of the device. The shaft is partially extended over a trajectory of a nozzle fitting carriage (2). The tubing lies in the shaft in a U-shape. A part of the tubing immovably lies in the shaft so that the tubing is moved from a nozzle fitting into the shaft during forward and return motions of the nozzle fitting carriage. The tubing directly contacts a shaft wall. The nozzle fitting is connected with the tubing as a supply line for liquid cleaning agent i.e. water.
