Background
The biological desulfurization is a novel biogas desulfurization method which takes desulfurization bacteria such as thiobacillus denitrificans and thiobacillus thiooxidans as main microbial flora and oxidizes hydrogen sulfide absorbed in alkali liquor into elemental sulfur.
The oxidation reactor is a key link in a biological desulfurization process, and mainly plays a role in carrying out biological oxidation treatment on absorption liquid flowing out of a methane absorption purification tower, oxidizing hydrogen sulfide and ionization products thereof in the absorption liquid into elemental sulfur under the action of desulfurization bacteria, and converting hydrogen ions in the desulfurization liquid into hydroxyl ions through redox electron transfer in the process, so that the alkalinity of the desulfurization liquid is recovered, and the next round of absorption desulfurization work is repeatedly carried out.
The desulfurization solution can generate a large amount of suspended sulfur after passing through the oxidation reactor, and the suspended sulfur has small particle size and is relatively stable in the solution, thereby causing great difficulty in the removal work. At present, a by-pass sulfur precipitator is generally adopted for removing sulfur, but in the method, the by-pass flow is low, so that the precipitation treatment capacity is limited, and the integral suspension sulfur removal effect on the desulfurization solution is poor. In this case, since a large amount of suspended sulfur enters the absorption tower together with the desulfurization solution, aggregation and accumulation are easily formed on the surface of the packing, thereby changing the flow condition of the absorption solution on the surface of the packing and deteriorating the desulfurization performance.
