よく用いられている。 When cleaning large, complex-shaped equipment that handles liquid metals such as sodium, primary cleaning (rough cleaning) and secondary cleaning are usually used to remove sodium adhering to the surface and clevis of the equipment. A cleaning process of next cleaning (finish cleaning) is adopted. As a primary cleaning method, there are cleaning methods such as an aqueous cleaning method, an alcohol cleaning method, and a vacuum distillation method, but the cleaning method using water is often used due to economical efficiency and cleaning efficiency.

る。 In this cleaning method, water vapor is transferred to a steam generator 5,
N 2 gas is supplied from the N 2 gas supply device 4 to the mixer 3 to form a mixture with a required moisture content, and then enters the cleaning tank 1 from the mixture supply system 6 . The mixture rises in the cleaning tank, and the sodium adhering to the object to be cleaned reacts with the water vapor, removing the sodium. Excess water vapor and N 2 gas mixture that do not participate in the reaction are discharged into the atmosphere from the exhaust system 8. in this way,
Since the air mixture sent into the cleaning tank is released into the atmosphere, large sodium equipment consumes a large amount of N 2 gas, and the longer the cleaning time, the more the consumption will increase.

This invention relates to an apparatus in which the exhaust system in the apparatus shown in FIG. 1 is connected to an inert gas supply system, and the released air-fuel mixture is removed and returned to the inert gas supply system for reuse.

It has a supply device 5, an exhaust pipe 8 connected to the upper part of the cleaning container 1, a gas separator 10 connected to the exhaust pipe 8, and a gas circulation path 9 connecting the gas separator 10 and the mixer 3. This invention relates to a liquid metal deposit cleaning device.

構造になつている。 Taking a case where sodium equipment is used as the object to be cleaned 2 and N 2 gas is used as the inert gas, the mixture of N 2 gas and water vapor (or water mist gas) mixed in the mixer 3 is as follows. , enters the cleaning tank 1 through the air-fuel mixture supply pipe 6 and rises to the object to be cleaned 2.
Sodium adhering to the gas reacts with water vapor (or water mist in the case of water mist gas), and the sodium is removed. The reaction product H 2 gas and the excess mixture gas are exhausted from the exhaust pipe 8, but enter the condenser 10, where water in the mixture is removed, and the N 2 gas further passes through the circulation pipe 9. A blower 11 installed in the middle allows the N 2 gas to enter the N 2 supply pipe again and be reused, so that the N 2 gas can be recycled and used.

用できる。 Generally, the air-fuel mixture used for cleaning is released into the atmosphere as is. However, in the present invention, only the N2 gas that is dehumidified by passing the exhaust gas mixture through the condenser can be reused via the gas circulation pipe. By recycling N 2 gas in this way, the amount of N 2 gas used can be minimized, resulting in significant savings in N 2 gas. H 2 gas, a reaction product of sodium and water vapor contained in the exhaust gas mixture, is exhausted from the exhaust pipe 8, and at this time, some N 2 gas is also exhausted. In addition, in this invention, as an inert gas,
Although N 2 gas is shown as an example, it can also be applied to Ar gas, etc.
