|Applicants:||XI'AN JIAOTONG UNIVERSITY
|Title:||SYSTEM AND METHOD FOR DRY CENTRIFUGAL GRANULATION OF HIGH_TEMPERATURE LIQUID SLAG AND EXHAUST HEAT RECOVERY|
A system and a method for the dry centrifugal granulation of high temperature liquid slag and exhaust heat recovery. The system comprises a liquid slag drainage system, a liquid slag buffering system, a liquid slag granulation and heat exchange system, a slag particle conveying system and an exhaust heat recovery system; the liquid slag drainage system comprises a slag groove (1), a baffle and a slag outlet (2); the liquid slag buffering system is composed of one or more independent slag containers, the slag container comprising structures such as a bag body (3), a bag cover (4), a slag pipe (5), and a stopper rod (6); the liquid slag granulation and heat exchange system is composed of one or more independent granulation and heat exchange systems which are arranged side by side in one or multiple rows, each granulation and heat exchange system being composed of a granulation bin (7), a centrifugal granulator (8), a movable bed (9) and a slag discharge device; the slag particle conveying system comprises a temperature-resistant conveyor belt (14) and a buffering material bin; the exhaust heat recovery system comprises a primary dust collector (15), an exhaust heat boiler (16), a secondary dust collector (17), an exhaust draught fan (18) and a chimney (19) which are connected in sequence.
