沼气脱硫的运行维护要达成什么标准?

沼气脱硫是一种简单,,成本相对较低的脱硫方法,也是一种应用更为广泛的脱硫方法。通过干式法从沼气中除去硫化氢的设备的基本原理是O2将硫化氢(H2S)氧化为硫或硫氧??化物的方法,也可以称为干氧化法。填充物放置在内部,填充层包括活性炭,氧化铁等。如今,氧化铁更为常用。气体以低流速从一端的入口进入容器,穿过容器中的填料层,硫化氢(H2S)被氧化成硫或硫氧化合物,并保留在填料层中。净化后的气体从容器另一端的出气口排出。
Biogas desulfurization is a simple, efficient, and relatively low-cost desulfurization method, and it is also a more widely used desulfurization method. The basic principle of equipment for removing hydrogen sulfide from biogas through dry method is that O2 oxidizes hydrogen sulfide (H2S) to sulfur or sulfur oxygen?? The method of chemical synthesis can also be called dry oxidation method. The filling material is placed inside, and the filling layer includes activated carbon, iron oxide, etc. Nowadays, iron oxide is more commonly used. The gas enters the container at a low flow rate from the inlet at one end, passes through the packing layer in the container, and hydrogen sulfide (H2S) is oxidized into sulfur or sulfur oxides, which are retained in the packing layer. The purified gas is discharged from the outlet on the other end of the container.
沼气脱硫的运行和维护应符合下列要求:
The operation and maintenance of biogas desulfurization should meet the following requirements:
沼气脱硫
1、脱水脱硫装置中的冷凝水应定期排放。当室外温度接近0°C时,应每天排放冷凝水,并在排放时防止沼气泄漏。
1. The condensate in the dehydration and desulfurization device should be discharged regularly. When the outdoor temperature approaches 0 ° C, condensate water should be discharged daily and biogas leakage should be prevented during discharge.
2、生物脱硫开始并正常进行后,应定期检查脱硫前后的硫化氢浓度变化,并且硫化氢的去除率应符合后端工艺的要求。当发现脱硫效率大大降低时,应及时补充循环的营养液。塔中的填料应每6-12个月清洁一次。
2. After the start and normal operation of biological desulfurization, the changes in hydrogen sulfide concentration before and after desulfurization should be regularly checked, and the removal rate of hydrogen sulfide should meet the requirements of the back-end process. When it is found that the desulfurization efficiency is greatly reduced, the circulating nutrient solution should be supplemented in a timely manner. The packing in the tower should be cleaned every 6-12 months.
3、应当定期检查干燥脱硫塔前后的硫化氢浓度和沼气压力变化。当不满足设计要求时,应更换脱硫剂或进行脱硫再生。
3. Regularly check the changes in hydrogen sulfide concentration and biogas pressure before and after drying the desulfurization tower. When the design requirements are not met, the desulfurization agent should be replaced or desulfurization regeneration should be carried out.
4、干式脱硫塔的再生应满足以下要求:
4. The regeneration of dry desulfurization tower should meet the following requirements:
1)在塔内使用脱硫剂进行再生时,应关闭沼气的进,出口阀门,并旁路支管和排放阀门管道应打开。
1) When using desulfurizer for regeneration in the tower, the inlet and outlet valves of the biogas should be closed, and the bypass branch pipe and discharge valve pipeline should be opened.
2)当使用在线脱硫器再生时,应根据沼气中的硫化氢含量确定空气混合量和空气流速,塔内温度应低于70℃,且塔内的氧含量脱硫塔出口沼气应小于1%3)脱硫剂应在2?3次再生后及时更换。更换脱硫剂时,操作员应戴防毒面具,房间应通风。
2) When using an online desulfurizer for regeneration, the air mixing amount and air flow rate should be determined based on the hydrogen sulfide content in the biogas. The temperature inside the tower should be less than 70 ℃, and the oxygen content inside the tower. The outlet biogas of the desulfurizer should be less than 1%. The desulfurizer should be at 2? Replace in a timely manner after 3 regenerations. When replacing the desulfurizer, the operator should wear a gas mask and the room should be ventilated.
4)沼气脱硫废脱硫器的处置应符合环境保护要求。
4) The disposal of biogas desulfurization waste desulfurizers should comply with environmental protection requirements.
