沼氣發(fā)電機組的未來(lái)發(fā)展前景是如何?
關(guān)于“沼氣”這種新興、清潔的能源,由于它突出具有高能、節能、安全 、環(huán)保等特點(diǎn),因而在未來(lái)它的應用前景是非常廣闊的。我國在沼氣的生產(chǎn)、收集、儲存及利用等方面的技術(shù)和設備也是日益成熟,那么為什么越來(lái)越多人選擇沼氣發(fā)電機組呢,這與它自身的特點(diǎn)是離不開(kāi)的。
As for "biogas", a new and clean energy source, "because it has the characteristics of high energy, energy saving, safety and environmental protection, its application prospect is very broad in the future. In China, the technology and equipment of biogas production, collection, storage and utilization are becoming more and more mature, so why more and more people choose biogas generator set? This is inseparable from its own characteristics.
1、受環(huán)境限 制小。沼氣發(fā)電機組的規模比較小,對場(chǎng)地的要求不高,只要有沼氣產(chǎn)生的地方基本上都可以進(jìn)行發(fā)電。不像水電一定建立在水力資源豐富的地方,而且還要考慮電站對周?chē)?態(tài)環(huán)境的影響;太陽(yáng)能發(fā)電要建在日照時(shí)間長(cháng)且比較偏僻的地方,因為太陽(yáng)能發(fā)電要占用大量的土地,一定考慮項目的經(jīng)濟性
1. Limited by the environment. The scale of biogas generating unit is relatively small, and the requirements for the site are not high. As long as there is biogas generating place, it can basically generate electricity. Unlike hydropower, which must be built in a place rich in hydraulic resources, but also consider the impact of the power station on the surrounding ecological environment; solar power should be built in a place with long sunshine and relatively remote, because solar power takes up a lot of land, and the economy of the project must be considered
2、可再 生,污染少。用沼氣進(jìn)行發(fā)電,不用擔心會(huì )有枯竭的。據統計,至2002年底世界剩余石油探明儲量為1407.04億噸。根據世界已探明的化石能源儲量推算,石油還可使用40~50年,天 然氣還可使用60~70年,煤炭則能維持225年左右??梢?jiàn),說(shuō)明化石能源離我們而去的日子已不遠。而以沼氣為代表的生物質(zhì)能源的壽命幾乎是無(wú)限的,只要太陽(yáng)存在,沼氣也將存在。
2. Renewable, less pollution. Using biogas to generate electricity, there is no need to worry that it will be exhausted one day. According to statistics, by the end of 2002, the world's remaining proven oil reserves were 140.704 billion tons. According to the proven fossil energy reserves in the world, oil can be used for another 40-50 years, natural gas for another 60-70 years, and coal for about 225 years. It can be seen that fossil energy is not far away from us. The life of biomass energy represented by biogas is almost unlimited. As long as the sun exists, biogas will also exist.
3、原料來(lái)源廣泛。沼氣發(fā)電機組的主要燃燒成分是甲烷,由甲烷產(chǎn)生菌厭氧消化有 機物產(chǎn)生。所以只要有 機物存在的地方,再配以適合的環(huán)境條件,就會(huì )有甲烷的生成。例如人畜的糞便、有 機工業(yè)廢水、垃圾填埋場(chǎng)、農作物秸稈等都可用做沼氣產(chǎn)生的原材料。今后隨著(zhù)畜禽養殖業(yè)和工業(yè)企業(yè)的發(fā)展,沼氣的生產(chǎn)量還會(huì )增加。
3. The sources of raw materials are wide. The main combustion component of biogas generator set is methane, which is produced by anaerobic digestion of organic matter by methane producing bacteria. So as long as the organic matter exists in the place, coupled with suitable environmental conditions, there will be methane generation. For example, human and animal manure, organic industrial wastewater, landfill, crop straw and so on can be used as raw materials for biogas production. In the future, with the development of animal husbandry and industrial enterprises, the production of biogas will increase.
