APPARATUS FOR REAGENT DISTRIBUTION IN THE FLUIDISED BED Russian patent published in 2022 - IPC C02F5/06 

FIELD: liquid handling.

SUBSTANCE: invention is intended for distributing reagents in the fluidised bed for softening water. Reagent distribution apparatus constitutes a vertical cylindrical column, wherein a distribution system with drainage caps for the input of water for softening is installed in the lower part thereof, and an outlet for collecting softened water is installed in the upper part. An apparatus for reagent distribution with a system for supply thereof is installed above the distribution system with drainage caps. The column is filled with a fluidised bed of a fine-grained material. An output for the spent sand — granules is made above the distribution system with drainage caps. The apparatus for reagent distribution is made movable and detachable and is connected through the top of the column with the reagent supply system via a vertical flexible hose and is supported in the fluidised bed by a cable linked with a lifting apparatus configured to adjust the submersion depth and lift the apparatus for reagent distribution through the top of the column.

EFFECT: lower crystal formation on the surface of the plate of the distribution system with drainage caps for water and on the distribution apparatus for the input of reagents.
