在能源越來越緊張,環(huán)保要求越來越高的形勢下,沼氣應(yīng)用對豐厚和完善能源構(gòu)造,緩解能源供需不均衡,進步可再生資源應(yīng)用率,減少不可再生能源耗費,防止廢棄物形成環(huán)境污染,降低工業(yè)、農(nóng)牧業(yè)、養(yǎng)殖業(yè)生成本錢,提升副產(chǎn)品應(yīng)用價值有實在的意義。因而,沼氣和沼氣相關(guān)技術(shù)(比如沼氣脫硫)開展需求留意以下幾點:
In the situation of more and more panic of energy and higher request for environmental protection, the application of biogas is of great 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, preventing waste from forming environmental pollution, reducing the cost of industrial, agricultural and animal husbandry, and raising the value of by-products. Therefore, we should pay attention to the following points in developing biogas technology:
(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(yīng)用和物質(zhì)循環(huán)應(yīng)用,既產(chǎn)生節(jié)能減排的公益性又帶來環(huán)境效益,政府應(yīng)加大財政補貼和扶持力度,給予一些優(yōu)惠政策,鼓舞開展;增強沼氣工程新技術(shù)和新設(shè)備研發(fā),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(yīng)用的小型沼氣應(yīng)用技術(shù)開發(fā);綜合應(yīng)用技術(shù)開發(fā),展開沼氣提純技術(shù),可使沼氣注入自然氣網(wǎng)用做燃料,或替代汽油、柴油用于車輛,完成沼氣利
(1) Improving the policy of encouraging renewable energy, aiming at the multi-level application of energy and material recycling in biogas engineering, which not only brings the public benefits of energy saving and emission reduction, but also brings environmental benefits, the government should increase financial subsidies and support, give some preferential policies to encourage the development, enhance the research and development of new technologies and equipment of biogas engineering, improve efficiency and reduce project cost. Especially the development of small-scale biogas application technology suitable for comprehensive application in remote areas and isolated islands; the development of comprehensive application technology 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 complete biogas benefits.
(2)沼氣發(fā)電和用于燃料電池,是有效應(yīng)用沼氣資源的新途徑,具有很大的開展?jié)摿?;沼氣用高端化,進步能源效益。
(2) Biogas power generation and fuel cell is a new way to effectively use biogas resources, which has great potential for development; high-end biogas is used to improve energy efficiency.
(3)對多原料高濃度結(jié)合發(fā)酵技術(shù)研討,保證產(chǎn)氣原料充足,進步安裝產(chǎn)氣率。沼氣工程向集中化、大型化的方向開展,進步工程經(jīng)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)推行沼氣鄉(xiāng)村開展,前景非常寬廣;完善和合理規(guī)劃養(yǎng)殖與種植產(chǎn)業(yè)規(guī)劃,完成資源綜合均衡應(yīng)用,減少保送本錢,進步效益。
(4) Promoting biogas rural development has broad prospects; perfecting and rationally planning the breeding and planting industry planning, completing the comprehensive and balanced application of resources, reducing the cost of delivery, and improving efficiency.
(5)沼氣脫硫技術(shù)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(huán)應(yīng)用。
(5) 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.
