PURPOSE:To capture the mist of a molten salt and to reutilize the same in a molten salt tank by providing perforated plates and rotary scraping vanes in multiple stages on the inside of a ventilation duct with a cooling jacket in the upper part of a molten salt tank and disposing a cyclone on the down stream side of the duct. CONSTITUTION:A steel material 10 is passed through the inside of a molten salt tank 20 in which a molten salt is bubbled in a bubbling header 30 to recover heat. The scattering mist of the molten salt is sucked by a blower 120 in this stage and is passed through a ventilation duct 70 to ventilate the inside of said tank. Since the duct 70 is cooled by a cooling jacket 60, the mist colliding against the duct 70 is cooled and sticks to the inside wall of the duct. The hole 81 parts of perforated plates 80 are disposed zigzag and therefore off most of the mist sticks to the plates 80 and is scraped off by the rotation of scraping vanes 70. The scraped mist is conveyed by the air gushing from the holes 81. The particles captured in a cyclone 110 and separated from the air fall into the tank 20 and are reutilized. |
