Abstract: A dust solidification system includes: a preduster for sucking dust with a negative pressure generated by a negative pressure generating source, removing solidification-inhibiting substances from the dust, and making the dust with a reduced solidification-inhibiting substance content rate flow toward the source; a dust capturing mechanism for capturing the dust flowing from the preduster and allowing the dust to fall; a storage tank for storing the dust captured by and falling from the capturing mechanism; and a dust solidifying mechanism for solidifying the dust in a forming chamber; and further includes one or more of the following: a dust re-scattering prevention mechanism for preventing re-scattering of the dust falling from the capturing mechanism; a stirring mechanism for stirring the dust loaded into the solidifying mechanism; and an air releasing mechanism for preventing air from entering the forming chamber by releasing air flowing into the storage tank from the solidifying mechanism.
