Powder slurry management device for wire saw

The purpose of this invention is to efficiently and effectively recycle dispersion from waste powder slurry of a wire saw through vacuum heating and drying and to ensure the safety of termination of the vacuum heating and drying operation. The solution of the present invention is a powder slurry management device for wire saw that comprises: a vacuum dryer (28) which can introduce waste powder slurry (8) from a wire saw (1) to carry out vacuum suction by a vacuum suction device (45) as well as introduce heating fluid (37) to an external steam cover (35) for heating; and condensers (43, 44) arranged at a vacuum pipeline (13) communicating the vacuum dryer (28) and the vacuum suction device (45) for cooling and liquefying steam (5a) from the vacuum dryer (28); in addition, the powder slurry management device for wire saw comprises: a cooling device (21) capable of converting heating fluid (37) to supply coolant water (20) to the steam cover (35) for cooling the vacuum dryer (28); and an inert gas supply device
