いる。2. Description of the Related Art Conventionally, when a liquid scintillation counter is used, radioactive organic waste liquid is discharged and it is necessary to treat it. However, the radioactive organic waste liquid of the liquid scintillator has various states. That is, when the radioactive sample is lipophilic, a toluene-based or xylene-based liquid scintillator is used, but when it is hydrophilic, a dioxane-based or an emulsifying scintillator containing a surfactant is used, and a tissue-solubilizing agent is also used. There is also an organic waste liquid obtained by decomposing biological samples. As such a treatment apparatus for radioactive organic waste liquid, as shown in FIG. 3, for example, the organic waste liquid H stored in the waste liquid tank 1 having the liquid level gauge 6 is forcibly forced by the metering pump 2 or the like into the combustion chamber 3 An incinerator is used in which the gas is introduced into the inside of the combustion chamber 3 and jetted into the combustion chamber 3 through a nozzle 4 and the gas is burned by a gas burner 5.

いという問題を有している。However, since the incinerator having the above-mentioned configuration is configured to simply store the radioactive organic waste liquid H in the waste liquid tank 1, the radioactive organic waste liquid H is stored during storage. The organic solvent / surfactant, etc. will be in a multi-layered or gelled state and cannot be kept in a uniform state at all times, and there is a possibility of explosion during combustion processing and stable incineration cannot be performed. I have a problem.

問題を有している。Further, since the radioactive organic waste liquid H is introduced into the combustion chamber 3 by jetting from the nozzle 4, the jetting of the nozzle 4 is particularly necessary when the radioactive organic waste liquid H has a high viscosity. The radioactive organic waste liquid H is accumulated in a solidified state at the outlet, which makes it impossible to perform an efficient incineration process, and it takes time to repair it.
