Patent number: 9744613Abstract: A flux recovery device that recovers a flux component from a gaseous mixture. The flux recovery device includes a first water spray unit that sprays water into a gaseous mixture containing the flux component, a separation unit that includes an introduction port for introducing the gaseous mixture into which water is sprayed from the first water spray unit, and a second water spray unit that forms a precipitation flow inside of the separation unit. The separation unit uses a swirling flow to separate the flux component from the gaseous mixture. A condensation unit cools water vapor generated in the separation unit to change the water vapor to water droplets, thereby removing the water vapor. Water vapor generated in a separation unit is cooled by a condensation unit, recovered as water droplets, and reused.Type: GrantFiled: June 13, 2014Date of Patent: August 29, 2017Assignee: Senju Metal Industry Co., Ltd.Inventors: Tsutomu Hiyama, Yuta Saito
