沼氣發(fā)電機(jī)組是必備的機(jī)器，其中Cat?（卡特）CG170系列機(jī)組具有較高的性價(jià)比優(yōu)勢(shì)：

A biogas generator set is an essential machine, among which Cat? The (Carter) CG170 series units have a high cost performance advantage:

高盈利能力：CG170系列機(jī)組發(fā)電效率高達(dá)44.2%。

High profitability: The CG170 series units have a power generation efficiency of up to 44.2%.

高穩(wěn)定性:基于無氣流燃燒和擴(kuò)大機(jī)油箱延長了維護(hù)保養(yǎng)間隔; 每年運(yùn)行時(shí)間高達(dá)8000小時(shí)或以上。

High stability: Based on no airflow combustion and expanding the oil tank, maintenance intervals are extended; The annual running time can reach 8000 hours or more.

最低潤滑油消耗量：潤滑油消耗率約為同等品牌機(jī)組的三分之一。

Minimum lubricating oil consumption: The lubricating oil consumption rate is about one-third of that of units of the same brand.

排放控制：高效清潔的燃燒滿足所有通用排放要求。

Emission control: Efficient and clean combustion meets all universal emission requirements.

氣體預(yù)處理及脫硫系統(tǒng)

Gas pretreatment and desulfurization system

氣體預(yù)處理系統(tǒng)主要包含除濕、過濾和穩(wěn)壓裝置，提供滿足發(fā)動(dòng)機(jī)啟動(dòng)和運(yùn)行的氣體。氣體預(yù)處理系統(tǒng)是沼氣發(fā)電機(jī)組必須配置的設(shè)備。

The gas pretreatment system mainly includes dehumidification, filtration, and stabilization devices, providing gas that meets the requirements of engine start and operation. The gas pretreatment system is a necessary equipment for the biogas generator set.

由于沼氣中通常含有H?S氣體，H?S氣體具有高度腐蝕性，任何發(fā)動(dòng)機(jī)對(duì)H?S均有一定的要求。當(dāng)沼氣中的H?S氣體含量高于發(fā)動(dòng)機(jī)要求時(shí)，一定要進(jìn)行脫硫處理。

Due to the usual presence of H in biogas? S gas, H? S gas has high corrosiveness, and any engine is sensitive to H? S has certain requirements. When H in biogas? When the S gas content exceeds the engine requirements, desulfurization treatment must be carried out.

脫硫方法有兩種：干法脫硫和濕法脫硫。對(duì)于高H?S含量氣體（H?S含量在10000ppm以上）時(shí)，通常采用濕法脫硫。濕法脫硫可以采用不同催化劑：絡(luò)合鐵、PDS等。

There are two types of desulfurization methods: dry desulfurization and wet desulfurization. For high H? Wet desulfurization is usually used for gases with an S-content (H-S content above 10000ppm). Wet desulfurization can use different catalysts such as complex iron and PDS.

脫硝裝置

Denitration device

沼氣發(fā)電機(jī)組是長期運(yùn)行的，且現(xiàn)有的環(huán)保法規(guī)越來越嚴(yán)格（對(duì)NOx的排放要求通常為100mg、80mg，甚至低至35mg。），脫硝裝置成為必備的要素。目前卡特彼勒燃?xì)獍l(fā)電機(jī)組有兩種排放類型：250mg 和 500mg NOx。其工作原理是利用尿素溶液或氨水作為還原劑，在催化劑的作用下將煙氣中的NOx 還原成N2排放在空氣中，減少污染。

Biogas power generation units operate for a long time, and existing environmental regulations are becoming increasingly strict (NOx emission requirements are usually 100mg, 80mg, and even as low as 35mg), making denitrification devices an essential element. At present, Caterpillar gas generators have two types of emissions: 250mg and 500mg NOx. Its working principle is to use urea solution or ammonia water as a reducing agent, under the action of a catalyst, to reduce NOx in the flue gas to N2 and discharge it into the air, reducing pollution.
