レーター下部に設置されている。 The microwave heating oven 1 is constructed of a stainless steel container in order to prevent microwaves from escaping to the outside and to isolate the atmosphere from the outside. A dripping device 2 is installed for dispensing as drops. Further, microwaves from the microwave oscillator 4 are irradiated into the oven 1 through a waveguide 3 connected to the oven 1. The dropped solution is heated by microwaves and an upward air current is generated in the oven, so this is prevented and a downward air current is maintained, and the pressure is reduced from the bottom of the oven as a mechanism to exhaust the gas generated during the heating and denitration process of the solution. Suction. A cyclone separator 5 is installed at the bottom of the oven to collect oxide powder generated by heating and denitrifying the solution, and this is connected to the exhaust blower 7 for vacuum suction.
and are connected by an exhaust pipe 6. Further, a powder container 8 for temporarily storing the oxide powder collected by the cyclone separator is installed below the cyclone separator.
