FIELD: process engineering.
SUBSTANCE: said filling may be used in process of metallurgy and chemistry wherein heated aggressive acid is used. Said filling consists of horizontal plates arranged one above the other on rigid cylindrical spacers provided with flexible element. Said filling allows countercurrent of solid and liquid phases over column height. RH and LH version of alternating plates varies pulp flow direction in horizontal plane through 180° between two pairs. Filling allows adjusting the stay of solids in apparatus to provide for required extraction of solid components into solution.
EFFECT: high mechanical strength and antirust properties.
