What is a good material for the filter screen at the inlet of the drying tower?
Thread Content
At present, the filter media used in the dryers of our system are mainly G3 filters; however, they need to be replaced after about a week. Additionally, the pressure drop across the demister in the dryers increases rapidly, requiring cleaning every approximately 2 months. I wonder if anyone has any good suggestions?
There is a problem with the system; is it sublimated sulfur or something else on the air distribution plate and the drying defoaming mesh? For the demisting screen in the drying tower, we use metal material.
We produce sulfuric acid from sulfur, and what is filtered is air
Reply to 3# tangbo415: What’s your environment like? How many layers of G3 filter media can be used? Our company, just like yours, has to replace them every 3 months at most, and the costs are very high. How is the structure of your air filter? Could you share that information?
We used only one layer, as the design called for just one layer from the start. There’s too much dust, making it difficult to clean; it needs to be replaced after a short time, and it’s also very expensive. I’m not sure if there are any good alternatives.
Is porous ceramic useful? I’m not sure if it can be used
I don’t know. Is there any relevant information you can share?
Some factories use filter cloths made of synthetic fibers, which can be removed and cleaned.
The filter area can be increased, with one filter in use and another as a backup; they are replaced and cleaned regularly for reuse.
At our factory, sponges are used at the inlet of the fans in the old sulfuric acid system, and the result is quite good
