Problems with sulfur dioxide fans in sulfuric acid plants
Thread Content
Problems with sulfur dioxide fans in sulfuric acid plants: For the fans used to convert sulfur dioxide in sulfuric acid plants, our company originally used two cantilevered fans – one large and one small, with capacities of 900 KW and 1100 KW respectively – but their operation was unstable. In 2017, we replaced one of these fans with a fan equipped with dual supports (900 KW), and its performance was much better. Now we want to upgrade the second fan as well, but due to limited space, this is not possible. As a result, people have suggested using rotary vane fans instead. I wonder if anyone has used rotary vane fans in such applications, and what are the experiences regarding their use and maintenance?
For this power level, the Roots blower isn’t necessarily small either; its noise poses a problem for occupational health.
Are there any specific parameters? Our fans have a very compact design; the factory is in the Czech Republic, so it might be possible to meet the requirements. We have manufactured 1500KW units for Chinalco, but the cost is relatively high

With an air volume of over 70,000, the fan is not considered large. I guess you used domestic fans before; Shenmu now offers both double-suction, double-support and cantilever fans. If possible, use KK&K fans; as a fallback option, Shenggu’s cantilevered fans can be used as well.
