摘要： PROBLEM TO BE SOLVED: To provide a vacuum degassing unit having a pre-heating apparatus, which is capable of favorably discharging drain built up in the lower part of a dust catcher, even when pre-heating operation of a vacuum degassing tanks is carried out over a long period of time.
SOLUTION: A first discharge pipe 11 is connected to a cylindrical part 4b at the lower part of the dust catcher, and a second discharge pipe 13 is connected to the first discharge pipe 11 via an elbow 12. The elbow 12 has nozzles 21 and 22 for discharging air through valves 15 and 16, respectively. The discharge of air through nozzles 21 and 22 purges the sites that are easily occluded and secures discharge passage for slurry-form drain. This enables smooth discharge of the drain and continuous preheating operation, even when a pre-heating exhaust gas from the vacuum degassing tank is allowed to enter into a gas cooler and produce the drain.
