Title: Carbonation column for sodium hydrogen carbonate prodn. - has perforated trays with drains adjacent vertical pipes
IPC: B01J19/00
Filed: 1976-03-23
Abstract: A carbonisation column for producing a suspension of sodium hydrogen carbonate contg. a solid crystalline phase comprises a series of perforated trays with vertical over-flow pipes passing through them, also a cooler in the lower part of the column. In each reaction chamber, the top of the vertical over-flow pipe is surrounded by a coaxial annular protector plate with an annular gap between them. The region of the tray immediately surrounding the pipe is unperforated and there is a discharge device, esp. an aperture in the pipe wall, at an appreciably lower level than the rim of the pipe, to permit discharge of the suspension together with the solid crystalline phase contained in it. As an alternative to the aperture, there is a separate small vertical drain pipe close to the vertical pipe. Uneven distribution of the solid phase across the tray, and accumulation of crystals, are reduced. Thus maintenance is reduced and a more uniform crystal size is obtd.
