Document Type and Number:
WIPO Patent Application WO/2021/057365
Kind Code:
A1
Abstract:
Disclosed is a comprehensive system for blast furnace slag removal and transport and a slag bath toxic water vapor pollution treatment, the system comprising a slag flushing unit (1), a slag and water separation unit (2), a slag conveying unit (3), and a water storage unit (4), wherein the slag flushing unit (1) comprises a slag flushing trench; the slag and water separation unit (2) comprises a slag and water separation portion (9); the slag conveying unit (3) comprises a slag conveying portion (10); the water storage unit (4) comprises a clean water storage portion (11); the slag flushing trench is connected to the slag and water separation portion (9); the slag and water separation portion (9) is respectively connected to the slag conveying portion (10) and the clean water storage portion (11); the slag and water separation portion (9) transfers separated slag to the slag conveying portion (10); the slag and water separation portion (9) transfers separated water to the clean water storage portion (11) after the water flows through a blind ditch; the clean water storage portion (11) is connected to the slag flushing trench by means of a trench; and the clean water storage portion (11) is provided with a blocking unit (5), and the blocking unit (5) prevents the toxic water vapor in the clean water storage portion (11) from being evaporated into the atmospheric environment.
