1. After the biogas is treated by the wet desulfurization tower, it shall be evenly distributed. The outlet shall be equipped with an online hydrogen sulfide monitor to accurately display the concentration of hydrogen sulfide. The content of hydrogen sulfide after desulfurization shall be controlled below 100ppm.
2. Desulfurization lean liquid enters the tower top through the spray liquid distribution device set at the top of the desulfurization tower, and the biogas enters the tower body from the bottom of the tower. The biogas and desulfurization liquid are fully contacted in the tower and between the feeding layers. Hydrogen sulfide in the biogas is completely absorbed by the desulfurization liquid, and the desulfurization rich liquid after absorbing hydrogen sulfide enters the rich liquid tank. The biogas after desulfurization is desulfurized by the desulfurization tower
3. Rich liquid tank: the rich liquid is separated from the rich liquid and flows into the rich liquid tank, where the rich liquid is buffered for ripening for a short time. A water seal device is set in the rich liquid tank to separate the biogas from the circulating system
4. Regeneration tank: reaction tank, in which an ejector is set, the desulfurization rich liquid conducts sulfur separation reaction, flows into the flotation cylinder through the tail pipe, and is further oxidized and regenerated in the flotation cylinder. Prepare for solution regeneration and sulfur foam separation.
5.貧液槽：再生后的脫硫液流入貧液槽緩存，由脫硫泵打入脫硫塔內進行脫硫反應。
5. Lean liquid tank: the regenerated desulfurization liquid flows into the lean liquid tank buffer, and is pumped into the desulfurization tower by the desulfurization pump for desulfurization reaction.
6.泡沫槽：儲存硫泡沫，供后續硫處理系統使用。
6. foam tank: store sulfur foam for subsequent sulfur treatment system.
