Description

Technical Field

[0001] This utility model relates to the field of desulfurization equipment technology, and in particular to an integrated biological desulfurization, degassing and sedimentation device. Background Technology

[0002] With increasingly stringent environmental protection requirements, flue gas desulfurization technology has been widely applied. Biological desulfurization, as an emerging technology, has attracted attention due to its low operating cost and environmental friendliness. Current biological desulfurization technology involves sending the desulfurization liquid, which absorbs hydrogen sulfide in the desulfurization tower, to a bioreactor for thorough aeration. The resulting sulfur slurry is first sent to a degassing tank to remove excess air, and then to a settling tank to separate elemental sulfur. The desulfurization liquid containing elemental sulfur is then returned to the desulfurization tower for reuse. In this existing technology, the sulfur slurry needs to pass through two devices—a degassing tank and a settling tank—before being separated into desulfurization liquid for reuse. This results in a large footprint for the biological desulfurization system, high manufacturing and transportation costs, cumbersome on-site installation and construction, and relatively troublesome maintenance.
