沼气湿法脱硫主要设备有哪些?性能怎么样?

1.沼气经湿法脱硫塔处理后,应布气均匀,出口处应设置硫化氢在线监测仪,精确显示硫化氢浓度,脱硫后硫化氢含量控制在100ppm以下。

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.脱硫贫液经由脱硫塔顶部设置的喷淋布液装置进入塔顶,沼气由塔底进入塔体,沼气与脱硫液在塔内及调料层间充分接触,沼气中的硫化氢被脱硫液完全吸收,吸收硫化氢后的脱硫富液进入富液槽,,脱硫后的沼气脱硫后的沼气由脱硫塔
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.富液槽:脱离富液流入富液槽,富液在槽内短时缓存熟化。富液槽内设置水封器,对沼气与循环系统进行分离
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.再生槽:反应槽,槽内设置喷射器,脱硫富液进行析硫反应,经过尾管流进浮选筒,在浮选筒进一步氧化再生。为溶液的再生和硫泡沫的分离做准备。
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.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 buffer, 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.
