<p>PURPOSE:To improve the recovery rate of the distillate, to facilitate the maintenance and inspection and to reduce the volume of the wastes by using a microwave as the source for heating and evaporating a liq. to be treated. CONSTITUTION:A microwave is irradiated on a liq. to be treated 10 charged in a heating furnace 9 from a microwave oscillator 1 and said liq. 10 is heated, evaporated and distilled. A gas is charged from a gas supply pipe 7 into a gas circulating chamber 30 between partition plates 5a and 5b and circulated to a damage detector 6 from a return pipe 8. The gas pressure in the gas circulating chamber 30 is always measured and the fluctuations of the pressure generated when the partition plates 5a and 5b are damaged are detected. Consequently, the recovery rate of the distillate is improved, the maintenance and inspection are facilitated and the volume of the wastes can be reduced.</p> |
