What determines the selection of the inclined tube settler and the SO2 desorption tower in the purification process?
Thread Content
As the title suggests, I’ve looked up a lot of information but couldn’t find any details on this topic
The inclined tube settler is designed based on the principle of shallow tank sedimentation； The degassing tower is designed based on the instability of sulfurous acid, with an operating gas velocity generally ranging from 0.5 to 0.7 m/s.
The settler is selected based on the amount of dilute acid to be treated and the mud content, while the desorption tower is chosen according to the gas flow rate
1# river9901: These two devices are not important; many different types can be used. The choice of such devices is quite arbitrary, and it can be said that the decision is made based on cost-effectiveness
Currently, in both domestic pyrite-based acid production systems and other acid production systems, Shanghai Xien Company’s CN filters are being used to replace traditional inclined tube settlers, whether during system upgrades or in the design of new projects. As for the selection of SO2 desorption towers, it is determined based on the volume of gas in the system.
