在能源越來越緊張,環保要求越來越高的形勢下,沼氣利用對豐富和完善能源結構,緩解能源供需不平衡,提高可再生資源利用率,減少不可再生能源消耗,避免廢棄物造成環境污染,降低工業、農牧業、養殖業生成成本,提升副產品利用價值有切實的意義。因此,沼氣脫硫技術發展需要注意以下幾點:
Under the situation of increasing energy shortage and environmental protection requirements, biogas utilization is of practical significance for enriching and improving energy structure, alleviating the imbalance between energy supply and demand, improving the utilization rate of renewable resources, reducing the consumption of non-renewable energy, avoiding environmental pollution caused by waste, reducing the production costs of industry, agriculture and animal husbandry, and raising the utilization value of by-products. Therefore, the development of biogas desulfurization technology needs to pay attention to the following points:
(1)完善可再生能源鼓勵政策,針對沼氣工程的能量多層次應用和物質循環應用,既產生節能減排的公益性又帶來環境效益,政府應加大財政補貼和扶持力度,給予一些優惠政策,鼓舞開展;
(1) To improve the policy of encouraging renewable energy, in view of the multi-level application of energy and material recycling in biogas projects, which not only produces the public benefits of energy conservation and emission reduction, but also brings environmental benefits, the government should increase financial subsidies and support, and give some preferential policies to encourage the development;
(2)增強沼氣工程新技術和新設備研發,進步效率,降低工程本錢。特別是合適偏僻地域和孤島等地綜合應用的小型沼氣應用技術開發;
(2) Enhance the research and development of new technologies and equipment for biogas engineering, improve efficiency and reduce project cost. Especially suitable for the development of small-scale biogas application technology in remote areas and isolated islands.
(3)對多原料高濃度結合發酵技術研討,保證產氣原料充足,進步安裝產氣率。沼氣工程向集中化、大型化的方向開展,進步工程經濟性和能源效率;
(3) Discuss the technology of multi-raw material high concentration combined with fermentation to ensure sufficient raw materials for gas production and improve installation gas production rate. The biogas project should be carried out in the direction of centralization and large-scale, so as to improve the economy and energy efficiency of the project.
(4)沼氣發電和用于燃料電池,是有效應用沼氣資源的新途徑,具有很大的開展潛力;
(4) Biogas power generation and fuel cell are new ways to effectively utilize biogas resources and have great potential for development.
(5)沼氣綜合應用技術開發,展開沼氣提純技術,可使沼氣注入自然氣網用做燃料,或替代汽油、柴油用于車輛,完成沼氣應用高端化,進步能源效益。
(5) The development of comprehensive application technology of biogas and the development of biogas purification technology can make biogas injected into natural gas network as fuel, or replace gasoline and diesel oil for vehicles to achieve high-end application of biogas and improve energy efficiency.
(6)完善和合理規劃養殖與種植產業規劃,完成資源綜合均衡應用,減少保送本錢,進步效益。
(6) Improve and rationally plan the breeding and planting industry planning, complete the comprehensive and balanced application of resources, reduce the cost of delivery, and improve efficiency.
(7)推行沼氣鄉村開展,前景非常寬廣;
(7) Promoting biogas rural development has broad prospects;
(8)沼氣脫硫技術開展相對較成熟,但仍有很多弊端,需進一步完善,防止形成二次污染,完成循環應用。
(8) Biogas desulfurization technology is relatively mature, but there are still many drawbacks, which need to be further improved to prevent secondary pollution and complete the cycle application.
