In particular, it relates to waste heat treatment equipment suitable for the treatment of waste containing heavy metals and waste with radioactivity. Any radioactive waste discarded from nuclear power generation facilities, nuclear fuel processing facilities, nuclear fuel reprocessing facilities, and other business facilities that utilize radioisotopes (R, I) is considered to be combustible. Regardless of whether they are flammable or non-flammable, they are harmful to the human body, so combustible items should be reduced in volume by incineration, and non-flammable items should be reduced in volume by means such as compression, crushing, or evaporative concentration. These incinerated ash and compressed materials are prepared for the purpose of detoxification and storage.

た実施例によって詳細に説明することとする。In view of the above-mentioned current situation, the present invention is aimed at disposing of wastes containing heavy metals or radioactive wastes through or without a continuous wall in a waveguide for guiding microwaves. The waveguide in the waste heat treatment equipment, which is made up of a series of heat treatment furnaces, is branched into two from the middle to the tip, and each waveguide is made into a separate waveguide. A waveguide selection switching member in the form of a switchable damper is provided to select which waveguide is used to guide microwaves among the different waveguides. Which of the separate waveguides is installed in the tip of one of the waveguides to airtightly isolate the inside of this waveguide and the inside of the heat treatment section, but it is also removable and can be used for microwave radiation. A microwave transmitting plate that transmits the microwaves is attached, and the continuous wall on the one side of the waveguide or the furnace wall of the heat treatment furnace is connected to an inert gas supply source, and an inert gas is connected to the microwave transmitting plate. The pipe port of the inert gas feed pipe that sprays the active gas and the inert gas fed through this feed pipe as well as the gas generated in the heat treatment furnace are sucked and discharged, and the inside of the heat treatment furnace is The outlet of the discharge pipe connected to a gas suction machine or the like is opened to create a slightly negative pressure, and the continuous wall or heat treatment on the other waveguide side of each of the separate waveguides is performed. The furnace wall of the furnace has a tube opening of an air supply pipe connected to the air supply source, and not only the air introduced by this supply pipe, but also the gas generated in the heating furnace is sucked and discharged, and the heating By making the waste heat treatment equipment open to the outlet of the discharge pipe connected to a gas suction machine, etc. to create a slightly negative pressure inside the furnace, the waste fed into the heat treatment furnace is made to be combustible. In the case of waste, the waste is placed in a heat treatment furnace connected to the waveguide on which the microwave transmission plate is attached inside the tip of the waveguide, and the waveguide selection switching member is The above waveguide is used to introduce microwaves into the heat treatment furnace, and the other waveguide is shut off and closed by a waveguide selection switching member, and an inert gas The surface of the microwave transmitting plate is wiped with an inert gas such as nitrogen gas through the inlet pipe, and the inert gas is fed into the heat treatment furnace while being protected by cooling, and the heat treatment is performed by suction and discharge operations performed through the discharge pipe. If microwaves are introduced into the heat treatment furnace with the inside of the furnace in a slightly negative pressure state, the microwaves will be introduced without reducing the transmittance of the microwave transmission plate.
The combustible waste can be safely dried and carbonized to become char, so at this point we stop introducing microwaves into the heat treatment furnace, and turn off the inert gas to the inert gas feed pipe. The supply of char and the suction/exhaust operation using the exhaust pipe are stopped, the heat treatment furnace containing the char is removed, and the other waveguide is connected to the tip of the waveguide, which is not equipped with a microwave transmission plate, through a continuous wall. Alternatively, the char may be taken out from the heat treatment furnace and attached to the tip of the waveguide to which the other microwave transmission plate is not attached, with or without a continuous wall. At the same time, the waveguide selection switching member is moved to the other side, air is introduced into the heat treatment furnace through the air inlet pipe, and the air is introduced into the heat treatment furnace through the discharge pipe. If the microwave is introduced into the heat treatment furnace through the waveguide that does not reduce the microwave performance in the slightest, the char will be burned and ashed, and this ash will be In the case of non-combustible waste, it is possible to vitrify it only by the latter operation. The basic heat treatment furnace can process two types of waste that are compatible with the composition of waste, and it is also possible to treat waste that contains heavy metals and radioactivity, which have caused various social problems in conventional treatment. In the treatment of waste, it is possible to reduce the volume to a degree that could not be dreamed of with conventional treatment methods of this type. We have made it possible to provide a waste heat treatment equipment that can be safely processed without leaching out harmful substances, which will not be eroded even if immersed in water or seawater. The present invention will be explained in detail below using examples illustrated in a flow sheet format.

なる。Since the waste heat treatment apparatus according to the present invention is configured as described above, when heat-treating the waste, it is possible to treat waste that is flammable, that is, contains volatile substances, or waste that is vaporized by heating. In the case of waste that is likely to generate ``6'' substances, first close one waveguide B side with the door 5 as a waveguide selection switching member, and place it in the retort 10 in the heat treatment furnace 3. The above-mentioned waste is administered, the heat treatment furnace 3 is sealed, and the gas inside the heat treatment furnace 3 is sucked and discharged through an exhaust pipe 8 connected to a suction machine, etc., while an inert gas feed pipe is used to Supply inert gas into the heat treatment furnace 3 while blowing the inert gas toward the microwave transmission plate 6 to create a slightly negative pressure inside the heat treatment furnace 3, and then use the waveguide A side. With the waveguide 1 configured as follows,
Microwaves of about 915 MHz or 2450 MHz generated by a microwave generator are guided to irradiate and heat the waste through the microwave transmission plate 6. Then, the waste is rapidly heated, subjected to rapid drying and carbonization treatment, etc., and the generated water vapor and cracked gas are discharged through the discharge pipe 8 together with the supplied inert gas, and the remainder is sent to the heat treatment furnace. It remains as a so-called char inside.

である。During this treatment work, although the cine active gas is supplied into the heat treatment furnace 3 through the inert gas feed pipe 7, exhaust through the exhaust pipe 8 is constant, and the inside of the heat treatment furnace 3 has a slightly negative pressure. In addition, the inert gas is supplied to the microwave transmission plate 6 which is airtightly mounted inside the tip of the waveguide A so as to wipe it off and protect it from cooling. Immigration Bureau 7
Since the water vapor and decomposition gas generated in the heat treatment furnace 3 will not enter the waveguide A of the waveguide 1, the waveguide 1 will not be corroded. This ensures that the microwave is always guided in a good state without being exposed to solid matter or being resistant to adhesion of solids in the gas.
At the same time, the microwave transmitting plate 6 is not only resistant to the adhesion of solid matter as described above, but also provides good microwave transmission without causing a decrease in microwave transmittance or deterioration due to the high temperature inside the heat treatment furnace 3. This will maintain the transmittance. Furthermore, a remarkable feature is that, as mentioned above, the inside of the heat treatment furnace 3 is always kept under a slightly negative pressure state, and there is no possibility of air being mixed in, so arc discharge and other This means that the danger of explosions caused by this will be eliminated.

には最適の処理の仕方ということができる。Then, air is supplied into the heat treatment furnace 3', and the gas inside the heat treatment furnace 3' is sucked and discharged through the exhaust pipe 15, and the inside of the heat treatment furnace 3' is made to have a slightly negative pressure. The microwave is guided by the waveguide 1, which closes the waveguide A side by rotating the door 5, which is a switching member, and uses the waveguide B side, which is free from any obstructions. When char is irradiated, the char is first oxidized and ashed, and the inorganic substances and ash are further heated to about 1200° or more depending on the melting point of the ash.
When the temperature reaches about 1500℃, these become a glass-like melt, and the remaining components contained in the waste are encapsulated in this melt, so if this is cooled, it becomes a glass-like melt. Therefore, the volume reduction rate of the waste is
It is not highly concentrated compared to conventional methods, and it is not eaten even if it is immersed in rainwater or seawater, so it is suitable for processing waste that contains heavy metals and radioactivity. This can be said to be the optimal method of processing.
