Selection of biogas fans for biological desulfurization of biogas
Thread Content
Operation overview: Anaerobic digestion produces biogas (containing hydrogen sulfide, other sulfur ethers, carbon dioxide, etc.). This gas undergoes biological desulfurization washing; the resulting purified biogas contains moisture and a small amount of hydrogen sulfide. It then enters the floating roof tank via a Roots blower (biogas fan). Usage: The biogas fan is made of cast iron; after about 3 years of use, air leakage occurred at the sealing area (oil seal). Upon inspection, it was found that corrosion of the shaft sleeve was to blame for the poor sealing performance of the oil seal. I would like to ask if anyone has any good methods or new types of fans that can eliminate this issue.
There are other types of fans available; I’ll send you a private message
I just sent it; I tried to add you on QQ, but you didn’t accept the request, and then I forgot about it:L
