GRANULATED CALCIUM CHLORIDE MANUFACTURE METHOD Russian patent published in 2004 - IPC

Abstract RU 2243161 C1

FIELD: nonferrous metallurgy.

SUBSTANCE: method consists in that concentrated calcium chloride solution is thermally treated when atomized in fluidized bed, which is created by flue gas flow passed from hearth under gas-distributing grid of furnace. Simultaneously, gas-distributing grid is chilled by introducing air into caisson part of gas-distributing grid to attain temperature difference 100 to 500^оС between flue gas and surface of grid contacting with fluidized bed, whereas temperature difference between this surface of grid and fluidized bed is 100 to 150^оС. Heated gas escaping gas-distributing grid is sent into hearth to form flue gas.

EFFECT: intensified granulation process.
