Fines removal apparatus installed on radioactive liquid waste granulat

A fines removal apparatus installed on a radioactive liquid waste granulator, the apparatus comprising:

• a body unit fastened to an outlet provided on the radioactive liquid waste granulator and configured to receive granulated radioactive waste by an operation of a first opening/closing valve provided at one side of the outlet, the radioactive liquid waste granulator being configured to manufacture concentrated liquid waste by evaporating moisture in radioactive liquid waste and to manufacture granulated radioactive waste by drying the concentrated liquid waste;
• an air supply unit provided on one side of the body unit and configured to spray air to the supplied granulated radioactive waste at regular periods, thereby scattering and separating fines contained in the granulated radioactive waste;
• a reprocessing unit provided in a vacuum state on an opposite side of the body unit and configured to allow the scattered fines to be transferred to the radioactive waste granulator along a transfer pipe by vacuum pressure when a second opening/closing valve provided on one side of the body unit is operated;
• an air supply pipe provided in a width direction inside the body unit and formed with a plurality of air supply nozzles in a circumferential direction along the width direction;
• and
• an air supply part connected to the air supply pipe and configured to supply air to the inside of the body unit through the air supply pipe;
• and
• an air chamber provided between the air supply pipe and the air supply part and configured to collect the supplied air.
