Then, the vapor A is cooled from the flow path 4 through each metal pipe 5 and separated into a gas G and a condensed liquid W, and is flown to the outflow pipe 22 through the flow path 4 of the lower header 3.

Then, the gas G and the liquid W are
The gas G passes through the circulation path 54 by the blower 53 and is returned to the heating tank 52 again. The liquid W is temporarily stored in the water tank 58 and gradually discharged.

In the capacitor 1, the upper header 2 and the lower header 3 are formed of rubber, and the mounting holes 6 are formed.
Is formed, and the metal pipes 5 are press-fitted into the mounting holes 6, so that the rubber headers 2, 3 and the stainless steel metal pipes 5 are exposed to the steam A of the strong acid at the joints. Therefore, the joint does not corrode.
