METHOD FOR REMOVING DEPOSITS AND/OR BIOFILMS IN A PIPE BY MEANS OF MODULATING PRESSURE IMPULSES

摘要

The method involves pressurizing gas or gas mixture in a line with a high pressure by modulating pressure impulses such that mini water blocks are formed in the line. The blocks are driven with a high speed through the line. A pressurized gas supply is directly readjusted with the same or high pressure after temporary lowering of the pressure built by the impulses in the partially emptied line such that other water blocks are formed. The former blocks are impacted by the latter blocks with high speed such that the former blocks obtain supplementary propulsion.
