Original acid mist and exhaust smoke
Thread Content
Recently, due to issues with the mineral source, there have been fluctuations in the baking process of the furnace. The pressure at the bottom of the furnace varies significantly, which results in an increased generation of acidic mist. As a result, power fluctuations occur, and the concentration of the diluted acid also increases accordingly. Is there smoke coming from the exhaust as well? Let’s discuss the connection between primary acid mist and exhaust smoke. Personally, I don’t think it matters much; the original acid mist is generated, and then it goes through purification processes such as washing, as well as electrostatic mist removal to eliminate the acid mist. The parameters related to the acid mist are within acceptable limits, the absorption rate is satisfactory, and the acid concentration is appropriate. Smoke from the exhaust is related to the original acid mist. But I disagree; high levels of original acid mist are the reason and main cause for exhaust smoke. Please give me some advice
Sulfuric acid production emphasizes stability and continuity in the manufacturing process. Fluctuations in raw materials require adjustments in operations, which leads to an increase in the sulfur trioxide content; this is reflected in an increase in the acidity of the purified dilute acid. Under normal operating conditions of the purification process, this generally does not result in excessive smoke being emitted from the exhaust gases ； As the furnace operation fluctuates, the entire system fluctuates as well; additional operations performed subsequently disrupt the systematic stability ； Or the additional operations are not carried out properly; under the influence of various factors, a slight carelessness can lead to excessive smoke being emitted from the exhaust. Check whether the moisture level at the outlet of the drying tower (if it is a fan located behind the tower, then check the fan’s outlet) fluctuates or exceeds the specified limits; this directly affects the exhaust gases. Heavy smoke from the exhaust is also clearly related to the efficiency of absorption by the dry cleaner; if the absorption is poor, it will show up in the exhaust fumes. The second suction goes without saying. (Other conventional checking methods are omitted here; feel free to offer criticism where applicable.)
Generally, it is due to an excessive moisture content in the flue gas (acid mist), which results in heavy smoke emissions
