Discussion on the causes of ash accumulation in the mixed flue of smelting in Guixi Smelter
The ash in the second series of sulphuric acid horizontal flue in Guixi Smelter is prone to deposition,leading to an increase in system resistance and affecting the long-term operation of the device.After analysis,low flue gas temperature,high air leakage rate and high generation ratio of SO3 make it easy for smelting flue gas to produce condensed acid,which is the main reason for ash deposition.By reasonably increasing the inlet flue gas temperature of the power wave scrubber,controlling the inlet pressure of the power wave scrubber,reducing the generation ratio of SO3 and regularly checking for leaks,the problem of ash accumulation in the flue of the second series of sulphuric acid has been effectively solved.
