物の減容化処理を提供するものである。 Granular ion exchange resins, powdered ion exchange resins for precoat filters, and precoat materials such as various cellulose materials (hereinafter collectively referred to as ``ion exchange resins, etc.'') are used for general water treatment and radioactive waste liquid treatment. . Since there is currently no suitable method for reducing the volume of used ion exchange resins, they are stored as they are, and an increase in the amount of them stored has become a problem. The present invention involves repeatedly heating and dehydrating waste such as ion exchange resin using microwaves, storing the waste in a movable container, and irradiating the waste with microwaves to reduce the volume. The present invention provides an effective waste volume reduction treatment characterized in that exhaust gas treatment is also performed using microwaves.

塵等の発生は公害の原因となり望ましくない。 Conventionally, when radioactive metal product waste or incineration ash is mainly composed of metal oxides, direct melting technology using microwave irradiation has been developed, taking advantage of the property that the treated material is a dielectric material. Generally, when processing radioactive waste, the generation of dust during the process is undesirable as it causes pollution.

もつていることが必要であり、廃棄物の含水率は
廃棄物の性状によつて適宜決定さるべきである。 In order to facilitate transportation, the waste such as ion exchange resin according to the present invention is extracted from the water treatment system in the form of a water slurry, but it is subjected to operations such as concentration, dehydration, drying, etc. It is desirable to remove most of the free water by drying, but if the material is difficult to scatter even when extremely dried, such as granular ion exchange resin, drying is performed as a pretreatment to remove the powdered ion exchange resin. If the moisture content is too low, it is necessary for the waste to have an appropriate moisture content, and the moisture content of the waste should be determined as appropriate depending on the nature of the waste. It is.

廃棄物を追加し再度マイクロ波を照射し減容化す
る。 After the waste has been reduced in volume, an appropriate amount of waste is added to the container again and the container is irradiated with microwaves again to reduce the volume.
本発明はこの操作をくり返し行うことによつて
多量の廃棄物を減容化し、小容量の容器に収容す

とが出来る。 Note that when storing waste in a container, it is desirable to measure the container before and after the container is stored so that a preset amount of waste is reduced in volume and stored in one container. In this case, if the level of waste in the container is measured using a level meter such as a capacitive level meter or an optical level meter, the waste can be disposed of even if there is a change in the volume reduction rate of the waste due to microwave irradiation. Adding objects to containers can be performed safely.

Glass forming agents such as CaO, SiO 2 , B 2 O 3 and PbO, asphalt or plastic are suitable, and it is desirable to add these substances and solidify them at the final stage of the volume reduction operation. If the solidifying agent is added to solidify the contents as a whole in this manner, handling after the volume reduction process becomes extremely easy.
以下本発明の一具体例を図面を用いて説明す
る。 A specific example of the present invention will be described below with reference to the drawings.
第１図は本発明の工程図である。 FIG. 1 is a process diagram of the present invention.
以下その工程に従つて説明する。 The process will be explained below.
１は廃棄物調整槽でイオン交換樹脂（粒状及び
粉末状）、繊維質プリコート材（ソルカフロツク、
KCフロツク等）が貯留槽から水ポンプ等を用い
て移送される。この場合対象物の種類により濃度
が異なるため一たん廃棄物調整槽に受け入れる。 1 is a waste adjustment tank that contains ion exchange resin (granular and powdered), fibrous precoat material (Solka Flock,
KC flocs, etc.) are transferred from the storage tank using a water pump, etc. In this case, since the concentration differs depending on the type of object, it is temporarily accepted into the waste adjustment tank.
２は沈降濃縮槽で廃棄物調整系に送られた物の

ある。濃縮物は重力脱水装置に送られる。 2 is a sedimentation concentration tank where there may be a large amount of excess moisture in the material sent to the waste adjustment system, and there are cases where the target waste is dispersed. In this case, if necessary, a coagulation aid or the like is added to coagulate and concentrate the dispersed waste. The supernatant water can be taken out by opening the valve attached to the sedimentation concentration tank. The concentrate is sent to a gravity dehydrator.
３は回分式重力脱水槽で対象廃棄物は水分（自

続し、対象とする試料の定量処理が可能なような
措置がとれるようにする。 3 is a batch type gravity dehydration tank, and since the target waste contains a lot of water (free water), it is inefficient to directly heat and incinerate it with microwaves, so it is necessary to remove as much free water as possible in advance. This dehydration system uses a perforated plate made of gold or steel inside the container to remove free water using gravity. The outlet of the container is connected to a device capable of quantitative supply, such as a rotary valve 5, so that measures can be taken to enable quantitative processing of the target sample.

はロータリーバルブ10等の機器を用いる。 Step 4 installs a drying system to remove water before incinerating the sample from which free water has been removed by gravity on a drying conveyor. The drying method is by microwave irradiation. As an example, the material to be dried is placed on a belt conveyor 4, etc., and passed through the microwave irradiation zone 4, during which vibrations of the contained molecules (internal molecular motion) are generated.
This generates heat and causes drying. Since the dielectric constant of water molecules is high, the heat generation efficiency is high. The dried sample is sent to the sample silo 8. From the sample silo, for example, the sample is sent to the sample rotating table 11 by a bucket conveyor 9. Note that a device such as a rotary valve 10 is used to introduce the sample into the sample rotating table.

行う。 FIG. 2 is an elevational view and a plan view of the sample rotating table 11. First, a new crucible to be used as a container is charged at position 11-1.A measuring device such as a load cell is installed at this position so that the weight of the charged material can be measured. The position 11-3 is a reserve, and the position 11-4 is a microwave irradiation position. Rather than directly irradiating at this position, the crucible containing waste is transferred to the microwave incinerator using a remote transfer device such as a manipulator. 11-2 after moving and completing irradiation incineration
Return to position 11-4, reinject the waste, return to position 11-4, and perform microwave treatment again in the same manner as the previous procedure.

合は遠隔操作で処理出来るようにする。 The position 11-5 is the position where the solid agent is introduced, and if waste such as ion exchange resin is incinerated using microwaves and a residue remains, it is thought that it will be solidified in the final stage. Suitable solid agents for this purpose include, for example, asphalt, thermoplastics, and also glass-forming agents such as substances that solidify after melting in the microwave, such as CaO, SiO 2 , B 2 O 3 , PbO, etc. , these solid agents are supplied from the solid agent supply tank 12 at the position 11-5. When the microwave incineration of the waste is completed and the injection of the solid agent is completed to form a solid waste, the crucible is taken out at the position 11-6. In the case of radioactive materials, it will be possible to dispose of them remotely.

The manipulator 13 is used to place the incinerator into the incinerator.In the case of a microwave incinerator, the waveguide for introducing microwaves at the top must be fixed, so the furnace itself is placed on a mechanism that moves it up and down, and the bottom part is lowered to place the crucible in the incinerator. After charging, raise the furnace to the top again to secure it.

It includes two steps: heating and dehydration, and 2) heating and incineration. During this step, the resin decomposes and generates amines, which are constituent factors of molecules. Some of these amines have a bad odor, and if they are released into the atmosphere as they are, they may cause bad odor pollution. Also, since the water-containing substance is heated, the water evaporates. For this reason, a cooler and condenser are installed in the exhaust gas system to remove moisture, and then the exhaust gas is passed through an off-gas treatment device. This off-gas treatment device sends microwaves generated by a microwave generator to a plasma generation torch to generate high-temperature plasma, and passes the off-gas through this plasma to heat and burn odor molecules and decompose them. . Since the exhaust gas contains fine particulate dust, it is removed through a filter system that combines coarse filters and high-performance filters.
