MALODOR REMOVING METHOD AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To remove a malodor generated at the time of thermally melting an asphalt material at a low cost with a simple method and device. SOLUTION: This malodor removing method is for removing a malodor 2a generated at the time of thermally melting an asphalt material 1. In such a case, an asphalt vapor 2 generated at the time of thermally melting the asphalt material 1 is collected and the collected asphalt vapor 2 is sucked into a surfactant solution 3 to make a volatile petroleum component in the asphalt vapor 2 absorbed and is discharged.
