PURPOSE:To improve the denitration effect, by means of a microwave-permeable covering vessel containing a sealed substance having a high specific inductive capacity provided on the bottom side of a dish-like vessel, containing a solution to be trated, and heatable from the bottom thereof. CONSTITUTION:The titled apparatus consisting of a metallic dish-like vessel 113 containing a solution 104 to be treated, a covering vessel 114, a substance 116 having a high specific inductive capacity, a safety valve 120 and a microwave generator 112. The above-mentioned covering vessel 114 is a microwave-permeable vessel forming a closed space 115 in the bottom of the metallic dish-like vessel 113, and the above-mentioned substnace 116 is sealed up in the space 115. The safety valve 120 is operated when the pressure of the closed space 115 reaches at the set pressure. The microwave generator 112 irradiates the solution 104 contained in the metallic dish-like vessel 113 with microwaves from above. The metallic dish-like vessel 113 is heated also from the bottom thereof by the above-mentioned apparatus, and the heat insulating effect is further obtained. Thus, the denitration effect is improved. |
