The working principle and advantages of a single fuel biogas generator set: the mixture of "air biogas" is compressed in a cylinder, burned with a spark plug, and powered by the reciprocating motion of the piston, which is then connected to the generator for power generation No need for auxiliary fuel oil and its supply equipment

② 燃料為一個(gè)系統(tǒng)，在控制方面比可燒兩種燃料的發(fā)電機(jī)組簡(jiǎn)單

② The fuel is a system that is simpler in control than a generator set that can burn two different fuels

③ 發(fā)電機(jī)組價(jià)格較低 雙燃料沼氣-柴油發(fā)電機(jī)組工作原理及優(yōu)點(diǎn)：將“空氣燃燒氣體”的混合物在氣缸內(nèi)壓縮，用點(diǎn)火燃料使其燃燒，通過活塞的往復(fù)運(yùn)動(dòng)得到動(dòng)力，然后連接發(fā)電機(jī)發(fā)電。

③ The working principle and advantages of a dual fuel biogas diesel generator set are as follows: the mixture of "air combustion gas" is compressed in the cylinder, ignited with ignition fuel, and powered by the reciprocating motion of the piston, which is then connected to the generator for power generation.

① 用液體燃料或氣體燃料都可工作

① It can work with both liquid and gas fuels

② 對(duì)沼氣的產(chǎn)量和甲烷濃度的變化能夠適應(yīng)

② Adapt to changes in biogas production and methane concentration

③ 如由用氣體燃料轉(zhuǎn)為用柴油燃料在停止工作，發(fā)電機(jī)組內(nèi)不殘留未燃燒的氣體，

③ If gas fuel is switched to diesel fuel and the generator set stops working, there will be no residual unburned gas inside,

因?yàn)轲I耐腐蝕性好 兩種沼氣發(fā)電機(jī)組缺點(diǎn):工作受到供給的沼氣的數(shù)量和質(zhì)量的影響 ① 用氣體燃料工作時(shí)也需要液體輔助燃料

Due to its good corrosion resistance, two types of biogas generator units have disadvantages: their operation is affected by the quantity and quality of biogas supplied. ① Liquid auxiliary fuel is also required when working with gas fuel

② 需要液體燃料供給設(shè)備 ③ 控制機(jī)構(gòu)稍復(fù)雜 ④ 價(jià)格較單燃料式發(fā)電機(jī)組稍高

② Require liquid fuel supply equipment ③ Control mechanism slightly complex ④ Price slightly higher than single fuel generator sets

沼氣池采用推流式厭氧發(fā)酵工藝，新建9個(gè)地下池，容積為1200立方米。沼氣池需達(dá)到10至25℃的常溫才能產(chǎn)氣，公司通過修建地下池、加厚土層保溫、利用發(fā)電機(jī)熱水和煙氣回收加溫、豬舍消毒水分流等手段，在現(xiàn)處冬季溫度1至3℃的氣候條件下，使沼氣池的溫度達(dá)到19℃以上，已安裝運(yùn)行近一個(gè)月的60千瓦沼氣發(fā)電機(jī)組，每天可發(fā)電6至8個(gè)小時(shí)，解決了冬季因溫度低不產(chǎn)氣發(fā)不了電的技術(shù)難題。到了夏秋兩季每天發(fā)電機(jī)組能發(fā)電10至12個(gè)小時(shí)，年發(fā)電量可達(dá)19萬千瓦/時(shí)，節(jié)省電費(fèi)30多萬元。

The biogas digester adopts a push flow anaerobic fermentation process, and 9 new underground tanks are built with a volume of 1200 cubic meters. The biogas digester needs to reach a normal temperature of 10 to 25 ℃ in order to produce gas. The company has built underground digesters, thickened soil layers for insulation, utilized generator hot water and flue gas recovery for heating, and disinfected pig houses for water flow. Under the current winter minimum temperature of 1 to 3 ℃, the temperature of the biogas digester can reach above 19 ℃. A 60 kW biogas generator set has been installed and operated for nearly a month, and can generate electricity for 6 to 8 hours per day, Solved the technical problem of not being able to generate electricity due to low temperature in winter. In the summer and autumn seasons, the power generation unit can generate 10-12 hours of electricity per day, with an annual power generation capacity of 190000 kilowatts per hour, saving over 300000 yuan in electricity bills.
