FIELD: pulp-and-paper and chemical industry.
SUBSTANCE: method involves preparing mixture of wet fibrous pulp and gaseous transportation agent; feeding resultant mixture into tubular reactor; feeding mean concentration fibrous semi-finished product into elevated tank and mechanically fluidizing for imparting fluidity upstream of pump impeller; feeding into pressing chamber for condensing to high concentration by squeezing and removing liquid; dispersing into fibers; providing fluidizing by mixing with transportation agent; pumping out to further processing station. Apparatus has elevated tank for receiving of fibrous semi-finished product, built-in screw with feeding coils; mechanical liquefier, pump impeller for pumping out of liquefied pulp into pressing chamber equipped with barometric tube for discharge of squeezed liquid and vacuum tube for removal of non-condensed gases. Dehydrating part of screw is mounted within pressing chamber. Apparatus is further provided with pulp mass plug, disperser, mixing chamber, and transportation pipeline. All functional mechanisms are mounted on single shaft which is fixed on pin of drive electric engine.
EFFECT: increased efficiency of process.
