What are the methods for dealing with exhaust gas containing liquid after sodium hydroxide solution absorbs sulfur dioxide?
Thread Content
After using sodium hydroxide solution to absorb sulfur dioxide, the exhaust gas carries liquid with it; this liquid falls within the factory area and dries out, turning white. Does anyone have any good solutions to address this problem?
First, it is necessary to examine the design data of the existing equipment to determine whether there are ways to make improvements； Secondly, a demister with good separation performance is added at the outlet to remove the liquid droplets from the purified gas.
Causes and measures for gas carrying liquid: 1. Excessive gas volume and high flow rate result in poor efficiency of droplet separation. Add washing towers to improve the washing and separation effects. 2. The demister is damaged or has low separation efficiency. Repair the demister or the previous high-efficiency demister. 3. The gas temperature is too high, resulting in poor washing efficiency and preventing effective separation of the liquid droplets. Lower the gas temperature to improve washing efficiency.
