PROBLEM TO BE SOLVED: To reduce the regeneration cost of an ion exchange resin by packing an ion exchange resin cylinder, wherein a cylinder body and a lid are clamped, with an ion exchange resin housed in a housing bag. SOLUTION: An ion exchange resin cylinder is constituted of a cylinder body 20 and an upper lid 22 and the cylinder body 20 of the ion exchange resin cylinder is packed with an ion exchange resin 6 housed in a mesh like housing bag 24 made of polyproplylene. A female screw 20a is formed at the upper part of the cylinder body 20 and a male screw 22a is formed to the upper lid 22 to mutually fit and clamp the cylinder body 20 and the upper lid 22 of the ion exchange resin cylinder by the male and female screw 22a, 20a. By this constitution, the regeneration cost of the ion exchange resin 6 and be reduced and a recycle coolant can be inexpensively supplied. |
