The exhaust fan 4 and the exhaust pipe 6 draw away the air inside the purification chamber 19, creating a negative pressure inside the purification chamber 19. Through the negative pressure and the exhaust pipe 17, the gas inside the cyclone separator 14 is drawn away, thus creating a negative pressure inside the cyclone separator 14. This, in turn, creates a negative pressure inside the dust removal pipe 11 and the dust removal hood 9. After the steam dust is drawn away by the negative pressure, it is transported to the inside of the cyclone separator 14, where the steam dust is dispersed. The dust is centrifuged and separated. The heavier dust falls into the discharge pipe 5, while the separated gas is transported to the purification chamber 19 through the exhaust pipe 17.
