Document Type and Number:
WIPO Patent Application WO/2024/080182
Kind Code:
A1
Abstract:
The present invention provides a dust collector (31) comprising: a generated gas filter (31A); a cooling hopper (31B); a first discharge valve (31D) disposed on an introduction line (31Ba) of the cooling hopper (31B); a second discharge valve (31E) disposed on a discharge line (31Bc) of the cooling hopper (31B); a pressurizing part (31F) that executes a pressurizing operation to pressurize a recovery container (31Bb) of the cooling hopper (31B); a depressurizing part (31G) that executes a depressurizing operation to depressurize the recovery container (31Bb); and a control unit. The control unit provides control such that the pressurizing operation executed by the pressurizing part (31F) and the depressurizing operation executed by the depressurizing part (31G) are alternately repeatedly with the first discharge valve (31D) and the second discharge valve (31E) placed in a closed state, and then char recovered into the recovery container (31Bb) is discharged from the discharge line (31Bc) with the second discharge valve (31E) placed in an open state.
