APPARATUS FOR OBTAINING GRANULATED PRODUCTS Russian patent published in 1996 - IPC

FIELD: chemical engineering. SUBSTANCE: apparatus for product granulation has vertical cylindrical housing, gas-distributing grate, coaxial vertical gas-feed branch pipe fixed in it, branch pipe for gas feed under grate, tangential gas-feed branch pipe mounted in upper part of housing, pulverizer for spraying pulp or melt placed inside vertical gas-feed branch pipe whose upper face end is disposed above gas-distributing grate at the level of height of boiling layer, axial gas-exhaust branch pipe connected in upper part of housing and equipped with tapered hopper having cylindrical shell on its end and internal cone, branch pipe for feeding dispersed material and branch pipe for granule unloading. Gas-distributing grate is equipped with coaxially disposed tapered cones. Internal cone is fixed on vertical gas-feed branch pipe. External cone is fastened on gas-distributing grate. The face end of external tapered cone is disposed below the face end vertical gas-feed branch pipe. Branch pipe for feeding the dispersed material is mounted in upper part of housing above lower edge of tangential gas-feed branch pipe. The face end of cylindrical shell is disposed below the face end of internal cone. EFFECT: enhanced quality of granulated products obtained by spraying the solution or melt onto suspended layer of dispersible material, enhanced efficiency. 1 cl, 1 dwg
