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.
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.
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.
注意事項。
matters needing attention.
1.沼氣脫硫設備應由專人看管，沼氣管道上的所有閥門需要由專人進行調節(jié)。
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.沼氣脫硫設備附近應做到良好通風，以防設備附近沼氣聚積。
2. Good ventilation shall be provided near the biogas desulfurization equipment to prevent biogas accumulation near the equipment.
3.沼氣脫硫設備附近嚴禁動用明火。
3. Open fire is prohibited near the biogas desulfurization equipment.
4.沼氣脫硫設備長期停用應將沼氣管上的所有手動閥門關閉。
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.定期檢查沼氣管道上所有閥門的密閉性，防止發(fā)生沼氣泄漏事故。
5. Regularly check the tightness of all valves on the biogas pipeline to prevent biogas leakage accidents.
