沼氣發(fā)電工程
Biogas Power Generation Project
沼氣發(fā)電工程是集環(huán)保和節(jié)能于一體的能源綜合利用工程。它是利用工業(yè)、農(nóng)業(yè)或城鎮(zhèn)生活中的大量有機廢棄物（例如禽畜養(yǎng)殖場糞污，酒廠、食品廠等各種加工廠的有機廢棄物，餐廚垃圾、城市垃圾和污水等），經(jīng)厭氧發(fā)酵處理產(chǎn)生的沼氣，驅(qū)動沼氣發(fā)電機組發(fā)電上國家電網(wǎng)或工廠自用，也可用于溫室種植供熱。另外沼氣也可供工業(yè)與民用燃?xì)?，沼液作為液態(tài)有機肥，沼渣加工成固態(tài)有機肥，可以為農(nóng)作物種植提供肥料。
Biogas power generation system is an energy saving and environmental friendly system. It’s to use industrial waste (organic waste in winery,food factory and etc.),agricultural waste(farm animal waste) or municipal domestic waste(restaurant waste,kitchen waste,urban waste and etc.) to produce biogas by anaerobic fermentation. Power generated by biogas engine may be connected to grid or self consumed. Waste heat from biogas engine may be used in production of biogas(anaerobic fermentation),greenhouse heating, industrial heat supply or civil heat supply. Besides, biogas may also be used as industrial fuel gas or civil fuel gas. Biogas liquid is used as liquid organic fertilizer. Biogas residue may be processed to solid organic fertilizer used in agriculture.
沼氣發(fā)電技術(shù)本身提供的是清潔能源，不僅解決了沼氣工程中的環(huán)境問題、消耗了大量廢棄物、保護了環(huán)境、減少了溫室氣體的排放，而且變廢為寶，產(chǎn)生了大量的熱能和電能，符合能源再循環(huán)利用的環(huán)保理念，同時也帶來巨大的經(jīng)濟效益。沼氣發(fā)電具有創(chuàng)效、節(jié)能、安全和環(huán)保等特點，是一種分布廣泛且廉價額分布式能源。
沼氣發(fā)電在發(fā)達國家已受到廣泛重視和積極推廣。生物質(zhì)能發(fā)電并網(wǎng)在西歐一些國家占能源總量的10%左右。
Organic wastes are converted to heat and electricity in the biogas power generating system. Biogas power generating system is a clean,efficient,economic and safe power generating system. It’s valued and widely spread in developed countries. In some west European countries, grid power generated by biogas accounts for about 10% of the total amount of energy.

沼氣熱電聯(lián)產(chǎn)工藝流程
Biogas Cogeneration Process
禽畜養(yǎng)殖糞污，酒廠、食品廠等各種加工廠的有機廢棄物，廚余垃圾，秸稈、菜葉、草、樹葉等農(nóng)業(yè)廢棄物，經(jīng)處理后進行厭氧發(fā)酵，產(chǎn)生沼氣，電熱聯(lián)產(chǎn)。電能可上網(wǎng)銷售，余熱可為工業(yè)與居民供熱，也可用于溫室種植供熱。另外沼氣也可供工業(yè)與民用燃?xì)?，沼液作為液態(tài)有機肥，沼渣加工成固態(tài)有機肥，可以為農(nóng)作物種植提供肥料或銷售。
There are various waste that can be used as raw materials for producing biogas, such as agricultural wastes, kitchen garbage, and other organic wastes from livestock farms, breweries and food-processing plants. After proper pretreatment and anaerobic digestion, these organic wastes can be transfer into biogas, and then into electricity. Then power can be sold, while waste heat can be used for heating. Also, biogas can be used as fuel, while slurry can be used for liquid fertilizer, and solid biogas residual for solid fertilizers.
