        沼氣如何發(fā)電 沼氣發(fā)電機的工作原理

        返回 2024.08.26 來(lái)源:http://m.elmasticar.com 0

          一、沼氣如何發(fā)電

          How does biogas generate electricity?

          1、沼氣脫硫及穩壓、防爆設備:供發(fā)起機運用的沼氣要先通過(guò)脫硫設備,以削減硫化氫對發(fā)起機的腐蝕。

          Biogas desulfurization, voltage stabilization and explosion-proof equipment: The biogas for engine use must first pass through the desulfurization equipment to reduce the corrosion of hydrogen sulfide on the engine.

          2、進(jìn)氣調理體系:在進(jìn)氣總管上,需設置一套準確、活絡(luò )的燃氣混合器,以調理空氣和沼氣的混合份額。

          2. Intake conditioning system: On the intake manifold, a set of accurate and sensitive gas mixer needs to be installed to adjust the mixing ratio of air and biogas.

          3、發(fā)起機焚燒體系:沼氣的焚燒速度慢,關(guān)于本來(lái)運用汽油、柴油已及天然氣的發(fā)起機的焚燒體系要進(jìn)行必定程度的改造,以進(jìn)步焚燒功率,削減后焚燒表象,延伸工作壽數。

          3. Engine combustion system: The combustion speed of biogas is slow. The combustion system of engines that originally used gasoline, diesel and natural gas needs to be reformed to a certain extent to improve combustion efficiency, reduce post-combustion phenomena and extend service life.

          4、調速體系:若沼氣發(fā)電機組獨立工作,即以用電設備為負荷進(jìn)行工作,用電設備的并入和卸載都會(huì )使發(fā)電機的負荷發(fā)生動(dòng)搖。為了保證發(fā)電機組正常工作,沼氣發(fā)起機上的調速體系必不可少。

          4. Speed regulation system: If the biogas generator set works independently, that is, it works with electrical equipment as the load. The parallel connection and unloading of electrical equipment will cause fluctuations in the load of the generator. In order to ensure the normal operation of the generator set, the speed regulation system on the biogas engine is essential.

          5、預熱運用體系:選用預熱運用設備,對發(fā)起機冷卻水和排氣中的熱量進(jìn)行運用,進(jìn)步沼氣的動(dòng)力運用功率。

          5. Preheating and utilization system: Select preheating and utilization equipment to utilize the heat in the engine cooling water and exhaust to improve the power utilization efficiency of biogas.

          6、并網(wǎng)控制體系:首要包含發(fā)電機調壓電路,主動(dòng)準同期并排控制電路,手動(dòng)并排寬和列控制電路,丈量電路,燃氣發(fā)起機及輔佐設備控制電路等。

          6. Grid-connected control system: mainly includes generator voltage regulation circuit, automatic quasi-synchronous parallel control circuit, manual parallel on and off control circuit, measurement circuit, gas engine and auxiliary equipment control circuit, etc.

          二、沼氣發(fā)電的優(yōu)勢

          Advantages of biogas power generation

          1、原料來(lái)源廣泛

          Wide range of raw material sources

          沼氣的主要燃燒成分是甲烷,由產(chǎn)甲烷菌厭氧消化有機物產(chǎn)生。所以只要有機物存在的地方,再配以適合的環(huán)境條件,就會(huì )有甲烷的生成。例如人畜的糞便、有機工業(yè)廢水、垃圾填埋場(chǎng)、農作物秸稈等都可用做沼氣產(chǎn)生的原材料。

          The main combustion component of biogas is methane, which is produced by the anaerobic digestion of organic matter by methanogens. So as long as there is organic matter and suitable environmental conditions, methane will be generated. For example, human and animal manure, organic industrial wastewater, landfills, crop straws, etc. can all be used as raw materials for biogas production.

          2、沼氣為可再生能源

          2. Biogas is a renewable energy source

          用沼氣進(jìn)行發(fā)電,不用擔心會(huì )有枯竭的一天。

          Using biogas for power generation, there is no need to worry about running out one day.

          3、沼氣發(fā)電清潔,污染少

          3. Biogas power generation is clean and causes less pollution

          沼氣中含有少量的硫化物,經(jīng)氣體預處理后硫化物的含量已經(jīng)降到很低的濃度,基本上不會(huì )對環(huán)境造成影響。

          Biogas contains a small amount of sulfide. After gas pretreatment, the content of sulfide has been reduced to a very low concentration and basically will not have an impact on the environment.

          4、沼氣發(fā)電建設規模小,工期短

          4. Biogas power generation has a small construction scale and a short construction period

          建立小型的沼氣發(fā)電站可以在幾周或幾月內實(shí)現,并且可根據需求的發(fā)展隨時(shí)增加和擴建,有利于資金的回收與周轉。

          A small biogas power station can be established within a few weeks or months, and it can be expanded and added at any time according to the development of demand, which is conducive to the recovery and turnover of funds.

          三、沼氣發(fā)電機組優(yōu)缺點(diǎn)

          Advantages and disadvantages of biogas generator sets

          其實(shí)沼氣發(fā)電機組分為兩種,一種是全部使用沼氣的單燃料沼氣發(fā)電機組,另一種是部分使用沼氣的雙燃料沼氣 - 柴油發(fā)電機組。

          In fact, biogas generator sets are divided into two types. One is a single-fuel biogas generator set that uses all biogas, and the other is a dual-fuel biogas-diesel generator set that uses part of biogas.

          單燃料沼氣發(fā)電機組工作原理:將 “空氣沼氣” 的混合物在氣缸內壓縮,用火花塞使其燃燒,通過(guò)活塞的往復運動(dòng)得到動(dòng)力,然后連接發(fā)電機發(fā)電。它具備如下優(yōu)點(diǎn):

          Working principle of single-fuel biogas generator set: Compress the mixture of "air and biogas" in the cylinder, use a spark plug to make it burn, obtain power through the reciprocating motion of the piston, and then connect the generator to generate electricity. It has the following advantages:

          1、不需要輔助燃料油及其供給設備

          No need for auxiliary fuel oil and its supply equipment.

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

          The fuel is a system, and it is simpler in control than a generator set that can burn two kinds of fuels.

          3、發(fā)電機組價(jià)格較低

          The price of the generator set is lower.

          雙燃料沼氣 - 柴油發(fā)電機組工作原理:將 “空氣燃燒氣體” 的混合物在氣缸內壓縮,用點(diǎn)火燃料使其燃燒,通過(guò)活塞的往復運動(dòng)得到動(dòng)力,然后連接發(fā)電機發(fā)電。它具備如下優(yōu)點(diǎn):

          Working principle of dual-fuel biogas-diesel generator set: Compress the mixture of "air and combustion gas" in the cylinder, use ignition fuel to make it burn, obtain power through the reciprocating motion of the piston, and then connect the generator to generate electricity. It has the following advantages:

          1、用液體燃料或氣體燃料都可工作

          It can work with either liquid fuel or gas fuel.

          2、對沼氣的產(chǎn)量和甲烷濃度的變化能夠適應

          It can adapt to changes in biogas production and methane concentration.

          3、如由用氣體燃料轉為用柴油燃料在停止工作,發(fā)電機組內不殘留未燃燒的氣體,因為餓耐腐蝕性好。

          If the gas fuel is changed to diesel fuel and the operation is stopped, there will be no unburned gas remaining in the generator set because of its good corrosion resistance.
