Abstract
The pipe system is for receiving and transporting lime sludge from a filter medium in a continuously operating pressurized filter in a causticizing process, where lime sludge is scraped off from the filter medium and falls down into receiving chutes for the lime sludge. Conventional storage tanks for scraped-off lime sludge and their mechanical agitators are thus replaced by a pipe system where the pipe system does not have a mechanical agitator at all but has a flow cross section which maintains a flow rate in the lime sludge so that sedimentation of the lime sludge does not take place from the receiving chute to the feed-out opening of the pipe system.
