Arrangement for chemical removal of pipeline deposits - uses chemical agent generating gas with deposits for ejecting loosened material

摘要

The arrangement for pipe system cleaning is used for removing sludge and especially line deposits in boiler pipes. This arrangement is used for cleaning convoluted pipes especially in hot water preparing systems. The arrangement has enclosed tank (15) for holding liquid cleaning agent. The agent outlet is connected to one end of the pipes system. The agent reacts chemically with the deposited material forming pressurised gas. The gas pressure is used for generating ejecting force. The water level arrangement ensures that the agent is introduced intermittently depending on the gas pressure in the pipes system.
