工作原理深度解析?

Deep analysis of working principle

沼氣發(fā)電機組的運作基于內(nèi)燃機原理，巧妙地利用沼氣作為燃料來產(chǎn)生電能。其核心工作流程如下：首先，經(jīng)過預(yù)處理的沼氣被輸送至儲氣罐，確保穩(wěn)定的氣源供應(yīng)。從儲氣罐輸出的沼氣，通過管道進入混合器，在混合器中與適量的空氣充分混合，形成可燃混合氣。此混合氣的空燃比至關(guān)重要，需根據(jù)沼氣的成分和發(fā)電機組的運行工況進行精準調(diào)節(jié)，以保障高效燃燒。?

The operation of biogas generators is based on the principle of internal combustion engines, cleverly utilizing biogas as fuel to generate electricity. The core workflow is as follows: Firstly, the pre treated biogas is transported to the gas storage tank to ensure a stable gas supply. The biogas output from the gas storage tank enters the mixer through the pipeline and is fully mixed with an appropriate amount of air in the mixer to form a combustible mixture. The air-fuel ratio of this mixture is crucial and needs to be accurately adjusted according to the composition of biogas and the operating conditions of the generator set to ensure efficient combustion. ?

形成的可燃混合氣隨后進入發(fā)動機的燃燒室。在燃燒室內(nèi)，混合氣通過火花塞點火（部分機型采用壓燃方式），瞬間劇烈燃燒，釋放出大量的熱能，使燃燒室內(nèi)的氣體溫度和壓力急劇升高。高溫高壓的氣體膨脹推動活塞做往復(fù)直線運動，通過連桿將活塞的直線運動轉(zhuǎn)化為曲軸的旋轉(zhuǎn)運動，從而將沼氣的化學(xué)能轉(zhuǎn)化為機械能。?

The formed combustible mixture then enters the combustion chamber of the engine. In the combustion chamber, the mixture is ignited by a spark plug (some models use compression ignition), instantly and violently burning, releasing a large amount of heat energy, causing the gas temperature and pressure in the combustion chamber to rise sharply. The expansion of high-temperature and high-pressure gas drives the piston to make reciprocating linear motion, which is converted into the rotational motion of the crankshaft through the connecting rod, thereby converting the chemical energy of biogas into mechanical energy. ?

曲軸的旋轉(zhuǎn)運動通過聯(lián)軸器傳遞至發(fā)電機。發(fā)電機內(nèi)部的電磁感應(yīng)裝置在曲軸的帶動下，將機械能轉(zhuǎn)化為電能輸出。在發(fā)電過程中，控制系統(tǒng)實時監(jiān)測發(fā)電機組的各項運行參數(shù)，如電壓、頻率、轉(zhuǎn)速、油溫、油壓等，并根據(jù)預(yù)設(shè)值自動調(diào)整進氣量、點火時間等關(guān)鍵參數(shù)，確保發(fā)電機組穩(wěn)定、高效運行，輸出符合標準的電能。?

The rotational motion of the crankshaft is transmitted to the generator through a coupling. The electromagnetic induction device inside the generator converts mechanical energy into electrical energy output under the drive of the crankshaft. During the power generation process, the control system monitors various operating parameters of the generator set in real time, such as voltage, frequency, speed, oil temperature, oil pressure, etc., and automatically adjusts key parameters such as air intake and ignition time according to preset values to ensure stable and efficient operation of the generator set and output electrical energy that meets standards. ?

顯著技術(shù)優(yōu)勢彰顯?

Significant technological advantages are highlighted

沼氣發(fā)電機組具有顯著的環(huán)保效益。沼氣作為一種清潔能源，主要成分是甲烷，燃燒時產(chǎn)生的污染物相較于傳統(tǒng)化石能源大幅減少。與煤炭發(fā)電相比，沼氣發(fā)電幾乎不產(chǎn)生二氧化硫、煙塵等污染物，氮氧化物的排放也能通過先進的尾氣處理技術(shù)控制在較低水平，有效降低了對大氣環(huán)境的污染。同時，沼氣的產(chǎn)生來源于有機廢棄物，如畜禽糞便、農(nóng)作物秸稈、工業(yè)有機廢水等，通過對這些廢棄物進行厭氧發(fā)酵產(chǎn)生沼氣并用于發(fā)電，既實現(xiàn)了廢棄物的資源化利用，減少了廢棄物對環(huán)境的污染，又緩解了能源短缺問題，具有良好的生態(tài)環(huán)境效益。?

Biogas generator sets have significant environmental benefits. Biogas, as a clean energy source, is mainly composed of methane, and the pollutants generated during combustion are significantly reduced compared to traditional fossil fuels. Compared with coal-fired power generation, biogas power generation produces almost no pollutants such as sulfur dioxide and smoke, and the emission of nitrogen oxides can also be controlled at a lower level through advanced tail gas treatment technology, effectively reducing pollution to the atmospheric environment. At the same time, the generation of biogas comes from organic waste such as livestock manure, crop straw, industrial organic wastewater, etc. By anaerobically fermenting these wastes to produce biogas and using it for power generation, it not only realizes the resource utilization of waste, reduces the pollution of waste to the environment, but also alleviates the problem of energy shortage, and has good ecological and environmental benefits. ?
