沼氣發(fā)動機主要有兩種利用沼氣具體形式，一種是驅(qū)動發(fā)電機發(fā)電，向廠內(nèi)供電或送入市電網(wǎng)，供電器用電；另一種是直接驅(qū)動鼓風機，節(jié)省電能。而沼氣發(fā)動機本身的熱量可向污泥厭氧中溫消化供余熱。下面沼氣發(fā)電機組廠家為您講說。

The biogas engine mainly uses biogas in two specific forms: one is to drive the generator to generate electricity, supply power to the plant or the municipal power grid, and the power supply device uses electricity; The other is to directly drive the blower to save electric energy. The heat of biogas engine can provide waste heat for anaerobic mesophilic digestion of sludge. Next, the manufacturer of biogas generator sets will tell you.

①這兩種利用沼氣的形式各有優(yōu)勢。前一種（發(fā)電機）的優(yōu)點較后一種（直接驅(qū)動鼓風機）運行靈活，可隨時發(fā)電供廠內(nèi)電器使用。

① The two forms of biogas utilization have their own advantages. The former (generator) has the advantages of flexible operation compared with the latter (directly driven blower), and can generate power at any time for the use of electrical appliances in the plant.

②兩種形式的機械效率不同。沼氣發(fā)動機的機械效率一般在20%～30%之間，當采用沼氣發(fā)電形式時，沼氣中的能量只有15%～23%轉(zhuǎn)化成了有效的機械能。當采用發(fā)動機直接驅(qū)動鼓風機時，其有效機械能為沼氣能量的20%～30%，相對沼氣發(fā)電機效率要高一些。

② The mechanical efficiency of the two forms is different. The mechanical efficiency of biogas engine is generally 20%~30%. When biogas power generation is adopted, only 15%~23% of the energy in biogas is converted into effective mechanical energy. When the engine is used to directly drive the blower, its effective mechanical energy is 20%~30% of the biogas energy, which is higher than the biogas generator efficiency.

③對于沼氣發(fā)動機來說，沼氣中的能量除20%～30%轉(zhuǎn)化成了機械能外，還有約30%以熱量的形式轉(zhuǎn)化到冷卻水中，30%以熱量的形式隨煙氣帶走，還剩10%為機體本身熱損耗和震動損耗，也就是說沼氣能量中約60%轉(zhuǎn)化成了熱量。

③ For biogas engines, in addition to 20%~30% of the energy in biogas is converted into mechanical energy, about 30% of the energy in biogas is converted into cooling water in the form of heat, 30% is taken away with flue gas in the form of heat, and 10% is the heat loss and vibration loss of the body itself, that is, about 60% of the energy in biogas is converted into heat.

④在實際生產(chǎn)中，通過有效的熱交換，30%的沼氣能量以90%的轉(zhuǎn)化率轉(zhuǎn)換到冷卻水中。另外30%的沼氣能量以65%的轉(zhuǎn)化率被回收用于加熱污泥，兩項共計利用率達47%～56%，即沼氣中能量的47%～56%被回收用于污泥加熱。綜合沼氣發(fā)動機所耗能量，沼氣能量的實際總利用率為67%～86%。

④ In actual production, 30% of biogas energy is converted to cooling water at 90% conversion rate through effective heat exchange. In addition, 30% of the biogas energy is recycled for heating sludge with a conversion rate of 65%. The total utilization rate of the two items is 47%~56%, that is, 47%~56% of the energy in the biogas is recycled for heating sludge. Considering the energy consumption of biogas engine, the actual total utilization rate of biogas energy is 67%~86%.

此外構成沼氣發(fā)電系統(tǒng)的主要設備有沼氣發(fā)電機組、發(fā)電機和熱回收裝置。沼氣經(jīng)脫硫器由貯氣罐供給燃氣發(fā)電機組，從而驅(qū)動與沼氣內(nèi)燃機相連接的發(fā)電機而產(chǎn)生電力。沼氣發(fā)電機組排出的冷卻水和廢氣中的熱量通過熱回收裝置進行回收后，作為沼氣發(fā)生器的加溫熱源。關注我們http://www.a7716.cn帶你了解更多內(nèi)容！

In addition, the main equipment constituting the biogas power generation system includes biogas generator set, generator and heat recovery device. The biogas is supplied to the gas generator set by the gas storage tank through the desulfurizer to drive the generator connected to the biogas internal combustion engine to generate electricity. The heat in the cooling water and waste gas discharged from the biogas generator set is recycled by the heat recovery device and used as the heating source of the biogas generator.
