As disclosed in Japanese Patent Publication No. 16384, a bag-shaped filter member made of a combustible material is sandwiched between respective sandwiching bars of a grid frame for attaching a filter member made of a combustible material, and a rivet or the like is synthesized. The edge of the bag-shaped filter member is screwed into the crosspiece by a resin screw fixing tool and fastened and fixed,
Further, in order to protect the filter member mounting lattice frame, the metal attachment rear frame is covered from behind the filter member mounting lattice frame, and the metal attachment front frame is formed from the front. The metal attachment was fitted so as to cover the outer periphery of the rear frame. The above-described nuclear bag filter has the above configuration, and all of the bag-shaped filter member, the filter-member-attached lattice-shaped frame, and the synthetic resin screw fixing member, excluding the metal attachment front frame and the rear frame. It could be incinerated. Therefore, when these were incinerated, the capacity after incineration could be significantly reduced, and the storage efficiency of radioactive waste in a disposal drum was significantly improved, which was excellent.

目的とする。It is desirable that the grid frame for attaching the filter member can be reused or reused. However, since the bag-shaped filter member is fastened and fixed to the filter member-attached lattice frame by a synthetic resin screw fastener such as a rivet, when the nuclear bag filter is disassembled, the filter member is attached. In some cases, a part of the filter member remains on the grid frame for use. Since there is a possibility that radioactive dust is attached to the bag-shaped filter member, the filter member-attaching grid frame in which the bag-shaped filter member remains cannot be reused or reused, and is incinerated. I had no choice. Therefore, the present invention facilitates separation of the bag-shaped filter member and the filter member mounting lattice frame of the nuclear bag filter, and enables the filter member mounting lattice frame to be reused or reused. It is an object of the present invention to provide a nuclear bag filter.
