<P>PROBLEM TO BE SOLVED: To provide a method for purifying the inside of a pressure-resistant container for blasting treatment in a short time after blasting treatment. <P>SOLUTION: The method includes: a step of setting an explosive 1 for purification for decomposing a part of a residue remaining in the pressure-resistant container 10, and a solid separating material 2 which collides with a substance adhered to an inner wall surface 32a of the pressure-resistant container 10, to separate the adhered substance from the inner wall surface 32a of the pressure-resistant container 10, in the pressure-resistant container 10; and a step of blasting the explosive 1 blasts in the pressure-resistant container 10 to decompose a part of the residue remaining in the pressure-resistant container 10, and dispersing the separating material 2 into a plurality of granular materials by the blast, while scattering the granular materials to collide with the inner wall surface 32a in the pressure-resistant container 10, for removing the adhered substance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
