沼气发电机组对沼气有什么具体要求

来源:http://www.huannengpower.com   发布于:2017-08-08

沼气是一种混合气体,主要成分是甲烷和二氧化碳。甲烷占45%~70%,二氧化碳占30%一40%,还有少量氢、一氧化碳、硫化氢、氧和氮等气体。由于含有可燃气体甲烷,故沼气可做燃料。沼气是细菌在厌氧条件下分解有机物的一种产物。

Methane is a mixture of methane and carbon dioxide. Methane accounted for 45% to 70%, carbon dioxide accounted for 30%, 40%, there are a small amount of hydrogen, carbon monoxide, hydrogen sulfide, oxygen and nitrogen and other gases. Methane can be used as fuel because of the presence of methane. Biogas is a product of bacteria decomposing organic matter under anaerobic conditions.

如果可燃气体中含硫及氨成分较高,不仅会严重腐蚀火花塞电极,而且会使机油中的酸值增加,腐蚀机组内部零件,同时易于生成沉淀物,增加对发动机的磨损和腐蚀。因为沼渣沼液始终是在密闭的发酵池内发酵沤制的,水溶性很大,养 分损失少,营养元素齐全,肥效高 、质量优。所以沼气发电后的沼渣沼液可做一下如此处理:

If the high content of sulfur and ammonia components of combustible gas, not only serious corrosion of spark plug electrodes, and the acid value of oil increased, corrosion unit internal parts, also easy to produce precipitate, increase of engine wear and corrosion. Because the biogas slurry is always fermentation retting in fermentation tank sealed, water soluble, less nutrient loss, nutrient complete, high efficiency and good quality. So biogas residue slurry to do so after a treatment:

1、作大田作物施肥。可以用作基肥和追肥方法与普通农家肥一样的作用。

1, for field crop fertilization. Can be used as base fertilizer and top dressing method and ordinary farmyard manure effect.

2、作花生施肥。作基肥,一将沼液泼淋于整好的花生地上,再、耕 耙一次。种上花生每亩施30担。二是开好行后,将沼液淋于行沟,再种花生,每亩施20担。

2, peanut fertilization. A fertilizer, biogas slurry pouring in the peanut field, then, a plough. Plant peanuts with 30 loads per mu. Two is to open a good line, the slurry will be poured in the ditch, and then planted peanuts, 20 kg per mu.

3、作瓜菜施肥。瓜菜幼苗时用沼肥,以1/3桶沼液冲2/3桶水淋根部,以后可以直接施用。

3, vegetable fertilization. When the seedlings with vegetables biogas fertilizer, biogas slurry with 1/3 barrels barrels of water rushed 2/3 with roots, later can be used directly.

4、种蘑菇用。用沼渣与基料堆沤种蘑菇,蘑菇产量可提高30%,出菇速度快,菇球均匀,质量好。

4. Use mushrooms. Use of biogas residue and the base material of retting kinds of mushrooms, mushroom yield can be increased by 30%, the mushroom mushroom ball speed, uniform, good quality.

5、作果树施肥。各种果树都可以施沼肥。

5, fertilization for fruit trees. All kinds of fruit trees can be manure.
