Renovation of the exhaust gas scrubber tower
Thread Content
Due to the poor cleaning efficiency of the exhaust gas scrubber in our company, the exhaust gases released pose a serious threat to the environment. Now we have decided to lead the vent pipe to the newly built tank beside it, at a depth of about 100 mm underwater, for another bubbling wash. I wonder how it works? Please analyze it, everyone!
You need to first determine whether the exhaust gas is acidic or alkaline. If it is acidic, it should be absorbed using an alkaline solution; if it is alkaline, an acidic solution should be used for absorption. In the case of organic gases, an organic solvent that can dissolve them must be used, otherwise the absorption effect will be poor! ! ! !
Yes, the ratio in the tank is very important. Tell me about the composition of your smoke gases??
A comprehensive understanding of the composition of exhaust gases is necessary; otherwise, simply using water for absorption will be ineffective； Just imagine, even after the water is absorbed, can’t it still not be discharged up to standard?
The exhaust gas scrubber needs to be modified; adding two trays or a small amount of packing inside it will yield much better results than using a water tank. The structure of the scrubber should be designed to enhance the gas-liquid contact, so that it doesn’t end up functioning as an ineffective tower. In other words, the distribution of gas and liquid needs to be more even. This will definitely improve the quality of the exhaust gas. Do you have any drawings? I can analyze them for you.
Suggestions: 1. Modify the exhaust gas scrubber system: The inlet gas and circulating liquid mix together in a venturi tube before entering the exhaust gas scrubber, at the lower part； A certain amount of graphite rings are placed inside the exhaust gas scrubber tower ； The circulating liquid enters the exhaust gas scrubber again via the middle and upper sections ； Maintain an appropriate concentration of the cleaning solution. ⒉Clean the exhaust gas using an exhaust gas cleaning chemical tank.
