どがその一例である。 In recent years, with advances in tracer technology for radioactive isotopes (hereinafter referred to as RI), tracer experiments using soft β nuclides such as 3H and 14C have become more frequent in a wide range of research fields in the natural sciences. . For example, in order to evaluate the safety of pharmaceuticals, experiments are conducted in which compounds labeled with 3 H, 14 C, etc. are administered to living organisms, and the fate of the drugs in the living body is investigated by understanding their distribution and metabolic status. This is an example.

止法の両法の規制を受けるのである。 The amount of RI used in these studies is usually extremely small, and liquid scintillation counting devices are generally used to measure it. Since a liquid scintillator prepared by dissolving naphthalene, etc. as a fluorescent agent in a solvent is used, a trace amount of
A large amount of liquid scintillator waste containing RI is generated at each business site, but since toluene and xylene used as solvents are classified as dangerous substances under the Fire Service Act, they cannot be stored in excess of a certain amount. Moreover, since the liquid scintillator waste liquid contains RI, albeit in a small amount, it is ``contaminated with radioactive isotopes'' as defined in the Disaster Prevention Act. It is subject to both laws.

であつた。 The liquid scintillator waste liquid used to be collected in bulk by the Japan Isotope Association and outsourced to the Japan Atomic Energy Research Institute for treatment. As a result, collection has been halted and the amount of stockpiled at each business site has increased significantly. Various studies are being conducted on how to dispose of it, and one of them is a method to directly incinerate waste liquid from liquid scintillators. However, many of the waste liquids contain a large amount of water, and direct combustion requires large-scale combustion equipment and full-time engineers, making it impossible to process at each business site. Moreover, even in the case of intensive treatment, as mentioned above, the waste liquid is
Since it is an organic solvent containing RI, considerable care is required in terms of equipment, technology, and handling in order to safely transport it, so it cannot be said to be a desirable treatment method. Therefore, recently, the waste liquid of liquid scintillator is subjected to aeration distillation.
A method of separating the distillation residue, which contains most of the RI, and the distillation fraction, which consists of an organic solvent and water, which contain a small amount of RI, and then treating each separately has been considered. According to this method, the distillation residue that contains most of the RI in the waste liquid does not contain organic solvents, so it is treated by solidification or other means to remove a trace amount of RI.
The distillate, which consists of an organic solvent containing RI and water, can be combusted so that the RI concentration in the exhaust gas falls below the legal concentration and the smoke concentration falls below the JIS standard. However, it is extremely difficult for conventional incinerators to burn the distillate safely and reliably.

き起すのである。 In other words, in conventional equipment, the waste liquid to be incinerated remains in the piping connecting the waste liquid tank and the incineration section even after the treatment is completed, so as the incineration process continues, the piping and accessories such as the pump become more contaminated with RI. As a result, operations essential to the operation and maintenance of the equipment, such as periodic inspections, troubleshooting, and parts replacement, become extremely dangerous, and the naphthalene used as a fluorescent agent in the accumulated waste liquid is leaked into the piping. By precipitating and crystallizing, the pipes and pumps become clogged, increasing the number of inspections and repairs.Furthermore, corrosive solvents such as ethanolamine in the waste liquid that accumulates in the pipes gradually clog the pipes and pumps. This eventually causes a hole and causes a serious problem of radioactive waste leakage.

できない。 The above problem can be solved by electrically controlling the pump using a float sensor that detects the amount of waste liquid in the waste liquid tank, so that no waste liquid remains in the waste liquid tank or in the piping. This can be solved to some extent by incinerating every drop of water, but
If the sensitivity of the float sensor is set so that it operates only when the waste liquid is completely exhausted, the air drawn into the pipe when there is little waste liquid remaining will form bubbles and block the pipe, causing combustion to stop. If the incineration process is controlled electrically, it is possible to prevent some waste liquid from remaining in the waste liquid tank or piping. It is not possible.

A nozzle 15 connected to the supply pipe 3 and an igniter 16 are housed in the tip part 14a, and the blower motor 13 is operated to introduce the required amount of air through the air supply pipe 14, and the burner pump is activated. 4 is activated to eject ignition oil etc. from the nozzle 15 and to spark the igniter 16 by the ignition transformer 17, the ignition oil etc. is burned in the incinerator and exhaust gas is discharged to the outside through the exhaust pipe 18. This is how it has become.

According to the signals output from the float sensors 5 and 6, the burner pump 4, solenoid valves 7 and 8, blower motor 13, and ignition transformer 1
7 to operate the device of the present invention as shown in FIG.

である。 That is, at the time of ignition, the ignition oil tank 1
It is detected whether kerosene is contained in the tank 2 and organic solvent waste liquid to be incinerated is contained in the waste liquid tank 2. If so, the solenoid valve 7 is opened and the burner pump 4 is activated. , the blower motor 13 and the ignition transformer 17 are also provided with output to burn only kerosene. This is because if the incinerator 12 spews out organic solvent waste and ignites it while the incinerator 12 is still at a low temperature, an explosion or incomplete combustion may occur. This is to prevent explosion accidents and incomplete combustion by combusting the organic solvent waste liquid after the combustion.

い。 Next, when the temperature switch 20 detects that the temperature inside the incinerator 12 has risen sufficiently, the solenoid valve 7
The solenoid valve 7 is left open for a while to incinerate the kerosene and waste liquid at the same time, and then the solenoid valve 7 is closed. The transition to the incineration mode is controlled by the output of the temperature switch 20 using the solenoid valves 7 and 8.
may be operated at the same time to instantly switch between kerosene and waste liquid, but from the perspective of interrupting combustion and preventing explosion accidents, the object spouted into the incinerator 12 may gradually change from kerosene to waste liquid. It is preferable to do so.

より決定するものとする。 On the other hand, when the float sensor 6 in the waste liquid tank 2 detects that most of the waste liquid has been incinerated, the control unit 19 opens the solenoid valve 7 while leaving the solenoid valve 8 as it is, and simultaneously incinerates the kerosene and waste liquid for a while. After that, the solenoid valve 7 is closed and the transition is made to the end, and the time during which both the solenoid valves 7 and 8 are open is such that when the float sensor 6 is activated, there is no space below the float sensor 6 or inside the pipe 10. The capacity of the waste liquid tank 2, the length of the piping 10, etc. shall be determined so that the remaining waste liquid is sufficient to be incinerated, and the time during which only the solenoid valve 7 is open and the kerosene is burned shall be determined. This is also determined based on the length of the piping 3, etc., so that it is sufficient to wash the waste liquid that accumulates and adheres to the piping 3, burner pump 4, nozzle 15, etc. during the incineration process.

することができるのである。 In the apparatus of the present invention, since the control unit 19 performs the control as described above at the end of the incineration process, there is no possibility that the organic solvent waste liquid will accumulate in the supply pipe 3 midway. Not only that, but since it is cleaned with kerosene, there is no risk that the piping, burner pump 4, etc. will be contaminated with RI, or that the solute will crystallize and clog the piping, etc. Also, from the time of incineration to the end, the float sensor 6
However, the transition is made by outputting a signal indicating that the waste liquid has been almost completely incinerated, and at this point there is still waste liquid remaining below the float sensor 6 and in the pipe 10. can be incinerated by keeping both electromagnetic valves 7 and 8 open for a certain period of time, and in the end, according to the apparatus of the present invention, it is possible to completely incinerate the waste liquid without leaving a single drop.
上記のように本発明装置を制御する制御部の構

When it is detected that kerosene is stored in the ignition oil tank 1 and waste liquid is stored in the waste liquid tank 2, the relays 23 and 24 are energized and their contacts S2
3. Since S24 is closed, the operation switch 25
When the blower motor 13 starts rotating, the flame detection circuit 28 connected to the flame sensor 21, the pre-purge timer circuit 29, and the ignition circuit 3 are connected to the flame sensor 21 by the transformer 26 and the DC power supply circuit 27.
After the blower motor 13 completes the pre-purge, the pre-purge timer circuit 29 energizes the relay 31, which closes the corresponding contact S31 to operate the burner pump 4 and open the solenoid valve 7, causing the ignition oil to flow. The kerosene in the tank 1 is jetted out from the nozzle, and at this point the ignition circuit 30
When the relay 32 is energized, the corresponding contact S32 is closed, the ignition transformer 17 is operated, the igniter 16 is sparked, and the kerosene starts to burn, and the device of the present invention is ready to ignite.
