奶牛养殖场的节能新路径！沼气脱硫+提纯，变废为宝提效又省钱

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

　　近几年奶价波动较大，不少大型奶牛养殖场都在琢磨着怎么降本增效。其中，把养殖过程中产生的大量牛粪“变废为宝”，通过沼气脱硫、提纯技术实现沼气资源化利用，成了越来越多养殖场的选择。就像我们服务的一家大型奶牛养殖场，两年前就安装了沼气脱硫、脱水、加压设备，近期又新上了两台大型沼气发电机，还专门整改了沼气管路，就是要最大化利用沼气发电，降低用电成本。今天就给大家科普，奶牛养殖场为啥要做沼气脱硫+提纯，这项技术又是如何实现节能提效的。

　　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.

　　先说说奶牛养殖场的核心痛点：一头奶牛每天会产生大量牛粪，这些牛粪如果处理不当，不仅会污染环境，还会产生高额的处理成本。而另一方面，养殖场的照明、挤奶设备、通风降温等都需要大量电力，电费也是一笔不小的开支。在奶价不理想的情况下，这两笔成本让不少养殖场压力山大。而沼气技术的出现，刚好打通了“废弃物处理”和“能源供应”的闭环，其中脱硫和提纯更是让沼气能稳定高效利用的关键。

　　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.

　　可能有朋友会问，直接用牛粪产的沼气发电不行吗？还真不行。刚从沼气池里出来的沼气，含有大量硫化氢等杂质，硫化氢是强腐蚀性气体，如果直接通入发电机，用不了多久就会腐蚀设备核心部件，导致发电机频繁故障，反而增加维修成本。这也是为啥那家奶牛养殖场两年前就先安装了沼气脱硫设备--脱硫是沼气利用的“第一道门槛”，通过专业设备去除沼气中的硫化氢，才能避免后续设备被腐蚀，保障发电系统稳定运行。

　　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.

　　光有脱硫还不够，要让沼气发电效率更高、用途更广泛，就离不开沼气提纯技术。简单来说，沼气脱硫是“除隐患”，而提纯是“提品质”。未经提纯的沼气，除了硫化氢，还含有大量二氧化碳，甲烷纯度较低，燃烧效率不高，发电功率也不稳定。而通过提纯技术，可以去除沼气中的二氧化碳等惰性气体，大幅提升甲烷纯度，让沼气的燃烧效率更高，产生的电能更多。对奶牛养殖场来说，提纯后的沼气发电效率提升，就能更好地满足场内用电需求，甚至多余电力还能并网销售，进一步增加收益。

　　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.

　　从实际应用流程来看，奶牛养殖场的沼气利用是个系统工程：先收集牛粪进行厌氧发酵产生沼气，沼气先经过脱硫、脱水、加压预处理--脱硫去除硫化氢，脱水减少水分对设备的影响，加压保障气体稳定输送；再通过提纯技术提升甲烷纯度，最后通入沼气发电机发电，供给场内各类设备使用。我们服务的那家养殖场，这次整改沼气管路、优化脱硫设备和发电机安装位置，就是为了让整个流程更顺畅，提升沼气利用效率。

　　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.

　　沼气脱硫+提纯技术给奶牛养殖场带来的好处可不止节能省钱。一方面，解决了牛粪污染问题，发酵后的沼渣、沼液还能作为有机肥料用于农田，实现“养殖-沼气-种植”的循环农业模式，进一步降低种植成本；另一方面，自主发电能减少养殖场对电网电力的依赖，哪怕遇到停电等突发情况，也能保障养殖设备正常运转，避免因设备停运影响奶牛养殖。就像那家养殖场，新上两台大型沼气发电机后，预计能大幅覆盖场内用电需求，电费成本能降低不少，在奶价波动的大环境下，相当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.

　　这里要给大家理清一个关键认知：沼气提纯不是可有可无的附加环节，而是提升沼气利用价值的核心。很多养殖场初期只做了脱硫处理，发现沼气发电效率不高、设备还是容易出问题，就是因为忽略了提纯。经过提纯的沼气，不仅发电效率高，还能根据需求进一步加工成生物天然气，用于更广泛的场景，比如供暖、汽车燃料等，让沼气的经济价值最大化。

　　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.

　　可能有小型养殖场会觉得，这套技术投入太高，自己用不起。其实对大型奶牛养殖场来说，前期投入虽然不低，但回报周期并不长。以我们服务的客户为例，随着沼气利用效率的提升，电费成本大幅降低，再加上废弃物处理成本的节省，用不了多久就能收回投入。而且现在有不少相关的环保补贴政策，也能减轻养殖场的投入压力。

　　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.

　　总结下来，奶牛养殖场采用沼气脱硫+提纯技术，是一条“变废为宝、节能提效”的好路子。它不仅解决了牛粪污染和用电成本高两大痛点，还能实现循环农业发展，提升养殖场的抗风险能力。随着环保要求越来越高、降本增效需求越来越迫切，这项技术会成为更多大型奶牛养殖场的选择。如果你的养殖场也面临类似的成本压力，不妨关注一下沼气脱硫和提纯技术，或许能找到新的节能增收路径。

　　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.
