奶牛養(yǎng)殖場的節(jié)能新路徑！沼氣脫硫+提純，變廢為寶提效又省錢

　　A new energy-saving path for dairy farms! Biogas desulfurization+purification, turning waste into treasure, improving efficiency and saving money

　　近幾年奶價波動較大，不少大型奶牛養(yǎng)殖場都在琢磨著怎么降本增效。其中，把養(yǎng)殖過程中產(chǎn)生的大量牛糞“變廢為寶”，通過沼氣脫硫、提純技術(shù)實現(xiàn)沼氣資源化利用，成了越來越多養(yǎng)殖場的選擇。就像我們服務(wù)的一家大型奶牛養(yǎng)殖場，兩年前就安裝了沼氣脫硫、脫水、加壓設(shè)備，近期又新上了兩臺大型沼氣發(fā)電機(jī)，還專門整改了沼氣管路，就是要最大化利用沼氣發(fā)電，降低用電成本。今天就給大家科普，奶牛養(yǎng)殖場為啥要做沼氣脫硫+提純，這項技術(shù)又是如何實現(xiàn)節(jié)能提效的。

　　In recent years, milk prices have fluctuated greatly, and many large dairy farms are considering how to reduce costs and increase efficiency. Among them, turning the large amount of cow manure generated during the breeding process into treasure and realizing the resource utilization of biogas through biogas desulfurization and purification technology has become the choice of more and more breeding farms. Just like a large dairy farm we serve, which installed biogas desulfurization, dehydration, and pressurization equipment two years ago. Recently, two new large-scale biogas generators have been installed, and the biogas pipeline has been specially renovated to maximize the use of biogas for power generation and reduce electricity costs. Today we will explain to you why dairy farms need to do biogas desulfurization and purification, and how this technology achieves energy conservation and efficiency improvement.

　　先說說奶牛養(yǎng)殖場的核心痛點：一頭奶牛每天會產(chǎn)生大量牛糞，這些牛糞如果處理不當(dāng)，不僅會污染環(huán)境，還會產(chǎn)生高額的處理成本。而另一方面，養(yǎng)殖場的照明、擠奶設(shè)備、通風(fēng)降溫等都需要大量電力，電費也是一筆不小的開支。在奶價不理想的情況下，這兩筆成本讓不少養(yǎng)殖場壓力山大。而沼氣技術(shù)的出現(xiàn)，剛好打通了“廢棄物處理”和“能源供應(yīng)”的閉環(huán)，其中脫硫和提純更是讓沼氣能穩(wěn)定高效利用的關(guān)鍵。

　　Firstly, let's talk about the core pain point of dairy farms: a cow produces a large amount of cow manure every day. If this manure is not handled properly, it not only pollutes the environment but also incurs high processing costs. On the other hand, lighting, milking equipment, ventilation and cooling in the breeding farm require a large amount of electricity, and electricity bills are also a significant expense. In the context of unfavorable milk prices, these two costs have put a lot of pressure on many farms. The emergence of biogas technology has just opened up the closed loop of "waste treatment" and "energy supply", among which desulfurization and purification are the key to ensuring stable and efficient utilization of biogas.

　　可能有朋友會問，直接用牛糞產(chǎn)的沼氣發(fā)電不行嗎？還真不行。剛從沼氣池里出來的沼氣，含有大量硫化氫等雜質(zhì)，硫化氫是強(qiáng)腐蝕性氣體，如果直接通入發(fā)電機(jī)，用不了多久就會腐蝕設(shè)備核心部件，導(dǎo)致發(fā)電機(jī)頻繁故障，反而增加維修成本。這也是為啥那家奶牛養(yǎng)殖場兩年前就先安裝了沼氣脫硫設(shè)備--脫硫是沼氣利用的“第一道門檻”，通過專業(yè)設(shè)備去除沼氣中的硫化氫，才能避免后續(xù)設(shè)備被腐蝕，保障發(fā)電系統(tǒng)穩(wěn)定運行。

　　Some friends may ask, is it not possible to directly use biogas produced from cow manure to generate electricity? It really doesn't work. The biogas that has just come out of the biogas digester contains a large amount of impurities such as hydrogen sulfide. Hydrogen sulfide is a highly corrosive gas. If it is directly introduced into the generator, it will soon corrode the core components of the equipment, causing frequent generator failures and increasing maintenance costs. That's also why that dairy farm installed biogas desulfurization equipment two years ago - desulfurization is the "first threshold" for biogas utilization. By using professional equipment to remove hydrogen sulfide from biogas, it can avoid subsequent equipment corrosion and ensure stable operation of the power generation system.

　　光有脫硫還不夠，要讓沼氣發(fā)電效率更高、用途更廣泛，就離不開沼氣提純技術(shù)。簡單來說，沼氣脫硫是“除隱患”，而提純是“提品質(zhì)”。未經(jīng)提純的沼氣，除了硫化氫，還含有大量二氧化碳，甲烷純度較低，燃燒效率不高，發(fā)電功率也不穩(wěn)定。而通過提純技術(shù)，可以去除沼氣中的二氧化碳等惰性氣體，大幅提升甲烷純度，讓沼氣的燃燒效率更高，產(chǎn)生的電能更多。對奶牛養(yǎng)殖場來說，提純后的沼氣發(fā)電效率提升，就能更好地滿足場內(nèi)用電需求，甚至多余電力還能并網(wǎng)銷售，進(jìn)一步增加收益。

　　Merely having desulfurization is not enough. To make biogas power generation more efficient and versatile, biogas purification technology is indispensable. Simply put, biogas desulfurization is about "eliminating hidden dangers", while purification is about "improving quality". Unprocessed biogas, in addition to hydrogen sulfide, also contains a large amount of carbon dioxide. Methane has low purity, low combustion efficiency, and unstable power generation. Through purification technology, inert gases such as carbon dioxide can be removed from biogas, greatly improving methane purity and increasing the combustion efficiency of biogas, resulting in more electricity generation. For dairy farms, the improved efficiency of purified biogas power generation can better meet the on-site electricity demand, and even excess electricity can be connected to the grid for sale, further increasing revenue.

　　從實際應(yīng)用流程來看，奶牛養(yǎng)殖場的沼氣利用是個系統(tǒng)工程：先收集牛糞進(jìn)行厭氧發(fā)酵產(chǎn)生沼氣，沼氣先經(jīng)過脫硫、脫水、加壓預(yù)處理--脫硫去除硫化氫，脫水減少水分對設(shè)備的影響，加壓保障氣體穩(wěn)定輸送；再通過提純技術(shù)提升甲烷純度，最后通入沼氣發(fā)電機(jī)發(fā)電，供給場內(nèi)各類設(shè)備使用。我們服務(wù)的那家養(yǎng)殖場，這次整改沼氣管路、優(yōu)化脫硫設(shè)備和發(fā)電機(jī)安裝位置，就是為了讓整個流程更順暢，提升沼氣利用效率。

　　From the perspective of practical application processes, the utilization of biogas in dairy farms is a systematic project: first, cow manure is collected for anaerobic fermentation to produce biogas. The biogas is first subjected to desulfurization, dehydration, and pressure pretreatment - desulfurization removes hydrogen sulfide, dehydration reduces the impact of water on equipment, and pressure ensures stable gas transportation; Further improve the purity of methane through purification technology, and finally feed it into a biogas generator to generate electricity and supply it to various equipment in the field. The livestock farm we serve has undergone a renovation of its biogas pipeline, optimized the installation location of desulfurization equipment and generators, in order to make the entire process smoother and improve the efficiency of biogas utilization.

　　沼氣脫硫+提純技術(shù)給奶牛養(yǎng)殖場帶來的好處可不止節(jié)能省錢。一方面，解決了牛糞污染問題，發(fā)酵后的沼渣、沼液還能作為有機(jī)肥料用于農(nóng)田，實現(xiàn)“養(yǎng)殖-沼氣-種植”的循環(huán)農(nóng)業(yè)模式，進(jìn)一步降低種植成本；另一方面，自主發(fā)電能減少養(yǎng)殖場對電網(wǎng)電力的依賴，哪怕遇到停電等突發(fā)情況，也能保障養(yǎng)殖設(shè)備正常運轉(zhuǎn)，避免因設(shè)備停運影響奶牛養(yǎng)殖。就像那家養(yǎng)殖場，新上兩臺大型沼氣發(fā)電機(jī)后，預(yù)計能大幅覆蓋場內(nèi)用電需求，電費成本能降低不少，在奶價波動的大環(huán)境下，相當(dāng)于多了一份盈利保障。

　　The benefits of biogas desulfurization and purification technology for dairy farms go beyond energy conservation and cost savings. On the one hand, the problem of cow manure pollution has been solved, and the fermented sludge and slurry can also be used as organic fertilizers in farmland, achieving a circular agriculture model of "breeding biogas planting" and further reducing planting costs; On the other hand, independent power generation can reduce the dependence of breeding farms on grid electricity. Even in the event of power outages or other emergencies, it can ensure the normal operation of breeding equipment and avoid the impact of equipment shutdown on dairy farming. Just like that breeding farm, with the addition of two large biogas generators, it is expected to significantly cover the electricity demand within the farm, reducing electricity costs significantly. In the context of fluctuating milk prices, it is equivalent to an additional profit guarantee.

　　這里要給大家理清一個關(guān)鍵認(rèn)知：沼氣提純不是可有可無的附加環(huán)節(jié)，而是提升沼氣利用價值的核心。很多養(yǎng)殖場初期只做了脫硫處理，發(fā)現(xiàn)沼氣發(fā)電效率不高、設(shè)備還是容易出問題，就是因為忽略了提純。經(jīng)過提純的沼氣，不僅發(fā)電效率高，還能根據(jù)需求進(jìn)一步加工成生物天然氣，用于更廣泛的場景，比如供暖、汽車燃料等，讓沼氣的經(jīng)濟(jì)價值最大化。

　　Here we need to clarify a key understanding: biogas purification is not an optional additional step, but the core of enhancing the value of biogas utilization. Many breeding farms only undergo desulfurization treatment in the initial stage, and it is found that the efficiency of biogas power generation is not high and equipment is still prone to problems, which is due to neglecting purification. Purified biogas not only has high power generation efficiency, but can also be further processed into bio natural gas according to demand, which can be used in a wider range of scenarios such as heating, automotive fuel, etc., maximizing the economic value of biogas.

　　可能有小型養(yǎng)殖場會覺得，這套技術(shù)投入太高，自己用不起。其實對大型奶牛養(yǎng)殖場來說，前期投入雖然不低，但回報周期并不長。以我們服務(wù)的客戶為例，隨著沼氣利用效率的提升，電費成本大幅降低，再加上廢棄物處理成本的節(jié)省，用不了多久就能收回投入。而且現(xiàn)在有不少相關(guān)的環(huán)保補(bǔ)貼政策，也能減輕養(yǎng)殖場的投入壓力。

　　Some small farms may feel that this technology requires too much investment and they cannot afford it themselves. In fact, for large dairy farms, although the initial investment is not low, the return period is not long. Taking our clients as an example, with the improvement of biogas utilization efficiency, electricity costs have significantly decreased, and coupled with the savings in waste disposal costs, it will not be long before the investment can be recovered. And now there are many related environmental subsidy policies that can also alleviate the investment pressure on breeding farms.

　　總結(jié)下來，奶牛養(yǎng)殖場采用沼氣脫硫+提純技術(shù)，是一條“變廢為寶、節(jié)能提效”的好路子。它不僅解決了牛糞污染和用電成本高兩大痛點，還能實現(xiàn)循環(huán)農(nóng)業(yè)發(fā)展，提升養(yǎng)殖場的抗風(fēng)險能力。隨著環(huán)保要求越來越高、降本增效需求越來越迫切，這項技術(shù)會成為更多大型奶牛養(yǎng)殖場的選擇。如果你的養(yǎng)殖場也面臨類似的成本壓力，不妨關(guān)注一下沼氣脫硫和提純技術(shù)，或許能找到新的節(jié)能增收路徑。

　　In summary, adopting biogas desulfurization and purification technology in dairy farms is a good way to turn waste into treasure, save energy and improve efficiency. It not only solves the two major pain points of cow manure pollution and high electricity costs, but also realizes the development of circular agriculture and enhances the risk resistance of breeding farms. With the increasing demand for environmental protection and the urgent need to reduce costs and increase efficiency, this technology will become the choice for more large-scale dairy farms. If your farm is also facing similar cost pressures, you may want to pay attention to biogas desulfurization and purification technology, which may find new energy-saving and income increasing paths.
