Method for cleaning an outer surface and use of a multi-jet rotating head in the cleaning method

摘要

The invention relates to a method for cleaning an outer surface (1) arranged at the bottom of a tank (3), a vessel or similar, comprising the steps of:
€¢ generating and supplying a pressurized cleaning fluid by means of a production source (2) of pressurized cleaning fluid, the fluid pressure being between 3 and 12 bar;
€¢ conveying the cleaning fluid opposite the said outer surface (1) of the tank (3) by circulating the fluid in a pipe network (4) arranged below the tank (3);
€¢ cleaning the outer surface (1) of the tank (3) by means of a plurality of rotating jets of cleaning fluid, the said plurality of jets being generated by at least one multi-jet rotating head (10) connected to the pipe network (4).
