沼气脱硫安全生产注意事项

2022-09-19

沼气是一种混合可燃气体，一般情况下，沼气的主要成分是甲烷和二氧化碳。此外，还有少量的氢、一氧化碳、氮、硫化氢等气体。甲烷含量占50%至70%，二氧化碳约占30%至40%左右。硫化氢含量在4000-5000ppm。

Biogas is a kind of mixed combustible gas. Generally, the main components of biogas are methane and carbon dioxide. In addition, there are a small amount of hydrogen, carbon monoxide, nitrogen, hydrogen sulfide and other gases. Methane accounts for 50% to 70%, and carbon dioxide accounts for about 30% to 40%. The hydrogen sulfide content is 4000-5000ppm.

1、沼气的爆炸性

1. Explosiveness of biogas

一般可燃气体都易与空气形成爆炸混合物，遇到明火就会爆炸，造成设备和人身事故。在使用沼气时，输送、贮存等沼气设施要求有较好的密封性及防爆措施。

Generally, combustible gas is easy to form explosive mixture with air, and will explode when encountering open fire, causing equipment and personal accidents. When biogas is used, transmission, storage and other biogas facilities are required to have good sealing and explosion-proof measures.

2、沼气的毒性

2. Toxicity of biogas

密闭空间中所含甲烷浓度高，使氧气含量下降，就会使人发生窒息，严重者会导致死亡。若空气中的甲烷含量达到25--30%时就会使人发生头痛、头晕、恶心、注意力不集中、动作不协调、乏力、四肢发软等症状。若空气中甲烷含量超过45-50%以上时就会因严重缺氧而出现呼吸困难、心动过速、昏迷以致窒息而死亡。

The high concentration of methane in the confined space will reduce the oxygen content, which will lead to asphyxia and death in serious cases. If the methane content in the air reaches 25-30%, people will suffer from headache, dizziness, nausea, inattention, uncoordinated movement, fatigue, limb weakness and other symptoms. If the methane content in the air exceeds 45-50%, it will cause dyspnea, tachycardia, coma and asphyxia due to severe hypoxia.

注意事项。

matters needing attention.

1.沼气脱硫设备应由专人看管，沼气管道上的所有阀门需要由专人进行调节。

1. The biogas desulfurization equipment shall be watched by a specially assigned person, and all valves on the biogas pipeline shall be adjusted by a specially assigned person.

2.沼气脱硫设备附近应做到良好通风，以防设备附近沼气聚积。

2. Good ventilation shall be provided near the biogas desulfurization equipment to prevent biogas accumulation near the equipment.

3.沼气脱硫设备附近严禁动用明火。

3. Open fire is prohibited near the biogas desulfurization equipment.

4.沼气脱硫设备长期停用应将沼气管上的所有手动阀门关闭。

4. When the biogas desulfurization equipment is out of service for a long time, all manual valves on the biogas pipe shall be closed.

5.定期检查沼气管道上所有阀门的密闭性，防止发生沼气泄漏事故。

5. Regularly check the tightness of all valves on the biogas pipeline to prevent biogas leakage accidents.
