<p><P>PROBLEM TO BE SOLVED: To provide a discharging system of discharging remaining liquid in a pipe while suppressing the amount of the remaining liquid to be treated as waste liquid. <P>SOLUTION: The discharging system 1 for discharging the remaining liquid in the pipe 9 from the interior of the pipe 9 includes: a circulation path 10 through which an ice water slurry as the mixture of ice and water circulates; a circulation pump 12 which circulates the ice water slurry in the circulation path 10; an ice water slurry concentrator 11 which is disposed in the circulation path 10, extracts water included in the ice water slurry circulating in the circulation path 10 using a filter, puts out the extracted water to the outside of the system of the circulation path 10 and, thereby, concentrates the ice water slurry in the circulation path 10; a sending path 14 through which the ice water slurry in the circulation path 10 concentrated by the ice water slurry concentrator 11, is fed into the pipe 9; and a discharge means 16 which force-feeds the ice water slurry concentrated by the ice water slurry concentrator 11 by sending the liquid into the pipe 9 and, as the result, discharges the remaining liquid. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
