1. After the biogas is treated by the wet desulfurization tower, the gas distribution shall be uniform. The outlet shall be equipped with an online hydrogen sulfide monitor to accurately display the hydrogen sulfide concentration. The hydrogen sulfide content after desulfurization shall be controlled below 100ppm.
2. The desulfurized lean liquid enters the tower top through the spray liquid distribution device set at the top of the desulfurizing tower. The biogas enters the tower body from the bottom of the tower. The biogas and the desulfurizing liquid are fully contacted in the tower and between the dressing layers. The hydrogen sulfide in the biogas is completely absorbed by the desulfurizing liquid. The desulfurized rich liquid after absorbing hydrogen sulfide enters the rich liquid tank. The desulfurized biogas and the desulfurized biogas pass through the desulfurizing tower
3. Rich liquid tank: separated from the rich liquid and flowed into the rich liquid tank. The rich liquid is buffered and matured in the tank for a short time. A water seal is set in the rich liquid tank to separate the biogas from the circulation system
4. Regeneration tank: the reaction tank is equipped with an ejector. The desulfurized rich liquid is subjected to sulfur separation reaction, flows into the flotation cylinder through the tail pipe, and is further oxidized and regenerated in the flotation cylinder. Prepare for regeneration of solution and separation of sulfur foam.
5.贫液槽：再生后的脱硫液流入贫液槽缓存，由脱硫泵打入脱硫塔内进行脱硫反应。
5. Lean liquid tank: the regenerated desulfurization liquid flows into the lean liquid tank for buffering, and is pumped into the desulfurization tower by the desulfurization pump for desulfurization reaction.
6.泡沫槽：储存硫泡沫，供后续硫处理系统使用
6. Foam tank: store sulfur foam for subsequent sulfur treatment system
