　　VOCs volatile gas recovery equipment must see! How long can the membrane structure last? One article explains it thoroughly

　　做VOCs挥发气回收相关的朋友们，不管是加油站、储油库，还是各类涉及油气挥发的场所，大家在选VOCs挥发气回收设备时，肯定都有一个共同的疑问：设备里的膜到底能用多久？毕竟膜是设备的核心部件，它的使用寿命，直接关系到设备的使用成本和运营效率，今天就不绕弯子，实打实地跟大家唠唠这件事，把膜结构的使用寿命、优势，还有和老款设备的区别，一条条讲透彻，不用死记硬背，听完你就全懂了。

　　For friends who are engaged in VOCs volatile gas recovery, whether it is gas stations, oil storage tanks, or various places involving oil and gas volatilization, when choosing VOCs volatile gas recovery equipment, everyone must have a common question: how long can the membrane in the equipment last? After all, the membrane is the core component of the equipment, and its service life is directly related to the equipment's operating cost and efficiency. Today, let's not go around the bush and talk to everyone about this matter in person. We will explain the service life, advantages, and differences between the membrane structure and the old equipment one by one, without rote memorization. After listening, you will understand everything.

　　首先跟大家回顾一下，以前咱们用的三次VOCs挥发气回收设备，大多是碳吸附式的，也就是大家常说的碳吸附设备。说实话，这种老款设备，用起来真的有不少麻烦，最头疼的就是废碳处理的问题——处理完VOCs挥发气后，会产生大量废碳，这些废碳属于固废，后续得专门花钱、费心去处理，不仅增加了运营成本，一旦处理不当，还可能造成二次污染。

　　Firstly, let me review with you that most of the three VOCs volatile gas recovery equipment we used in the past were carbon adsorption devices, which are commonly referred to as carbon adsorption equipment. To be honest, using these old devices can be quite troublesome, and the biggest headache is the issue of waste carbon treatment - after treating VOCs volatile gases, a large amount of waste carbon will be generated, which belongs to solid waste and requires special money and effort to be spent on subsequent treatment. This not only increases operating costs, but also may cause secondary pollution if not handled properly.

　　更让人操心的是，碳吸附设备的处理效果还不稳定，排放出来的气体经常达不到环保标准，稍微不注意，就会面临环保检查不合格、罚款的风险。尤其是现在国家对VOCs排放的要求越来越严，碳吸附设备的这些短板，越来越难满足合规运营的需求，所以现在大部分VOCs挥发气回收设备，都换成了膜结构的，慢慢淘汰了碳吸附式的老设备。

　　What is even more concerning is that the treatment effect of carbon adsorption equipment is still unstable, and the emitted gases often do not meet environmental standards. If not taken seriously, there is a risk of environmental inspection failure and fines. Especially now that the country's requirements for VOCs emissions are becoming increasingly strict, the shortcomings of carbon adsorption equipment are becoming increasingly difficult to meet the needs of compliant operation. Therefore, most VOCs volatile gas recovery equipment has been replaced with membrane structures, gradually phasing out old carbon adsorption equipment.

　　很多朋友刚接触膜结构的VOCs挥发气回收设备，最关心的还是核心问题：这个膜到底能用多久？会不会用个一两年就坏了，还得花钱更换？今天就给大家吃一颗定心丸，膜结构的设备，使用寿命远比大家想象的长，而且只要正常运行，基本不会损坏。

　　Many friends who are new to VOCs volatile gas recovery equipment with membrane structures are most concerned about the core issue: how long can this membrane last? Will it break after one or two years of use and require money to replace? Today, I will give you a reassurance pill. Membrane structured equipment has a much longer service life than you imagine, and as long as it operates normally, it will not be damaged.

　　从理论实验上来说，膜结构的核心优势的就是，它在过滤、分离VOCs挥发气分子的时候，油气分子只是透过膜进行分离、液化，并不会对膜的结构造成任何损伤或者损坏。简单来说，就是膜在工作过程中，不会有磨损、消耗，只要设备正常运行，没有人为损坏或者极端故障，这个膜是可以一直使用的，不存在“用久了就失效”的问题。

　　In theoretical experiments, the core advantage of membrane structure is that when filtering and separating VOCs volatile gas molecules, oil and gas molecules only pass through the membrane for separation and liquefaction, without causing any damage or destruction to the membrane structure. Simply put, the membrane will not wear or consume during operation. As long as the equipment is running normally and there is no human damage or extreme malfunction, the membrane can be used continuously without the problem of "failure after prolonged use".

　　光说理论可能大家还不放心，给大家说一个我们实际运营中的真实数据，更有说服力。我们最早安装的一批膜结构VOCs挥发气回收设备，到现在已经稳定运行了8年半的时间，期间没有更换过膜部件，而且设备处理后排放出来的油气，依然能达到国家环保标准，完全合格，没有出现过排放超标的情况。

　　Just talking about theory may not make you feel at ease. It would be more convincing to provide you with real data from our actual operations. The first batch of membrane structure VOCs volatile gas recovery equipment we installed has been running stably for 8 and a half years, during which the membrane components have not been replaced. Moreover, the oil and gas discharged after equipment treatment still meet the national environmental protection standards, fully qualified, and there have been no cases of excessive emissions.

　　这就足以说明，膜结构的VOCs挥发气回收设备，膜的使用寿命确实很长，不是我们夸大其词，而是经过实际检验的。可能有朋友会问，为什么膜能用到这么久？其实核心还是膜的材质和技术，现在膜结构设备采用的高分子分离膜，材质耐用、抗腐蚀，而且工作原理简单，不需要承受高强度的磨损，自然使用寿命就长。

　　This is sufficient to demonstrate that the membrane structure of VOCs volatile gas recovery equipment has a long service life, which is not an exaggeration, but has been tested in practice. Some friends may ask, why can the membrane be used for so long? In fact, the core is still the material and technology of the membrane. The polymer separation membrane used in membrane structure equipment is durable, corrosion-resistant, and has a simple working principle. It does not need to withstand high-intensity wear and tear, and has a long natural service life.

　　这里也跟大家补充一句，膜结构设备的使用寿命长，不仅能减少膜部件更换的成本，还能减少设备停机维修的时间，让VOCs挥发气回收工作持续稳定运行，不用频繁停工检修，间接节省了运营成本。这也是为什么现在越来越多的场所，都愿意换成膜结构的VOCs挥发气回收设备，比碳吸附设备省心、省钱太多。

　　Here I would also like to add that membrane structure equipment has a long service life, which not only reduces the cost of membrane component replacement, but also reduces the time for equipment shutdown and maintenance, allowing the VOCs volatile gas recovery work to operate continuously and stably without frequent shutdown and maintenance, indirectly saving operating costs. That's also why more and more places are willing to switch to membrane structure VOCs volatile gas recovery equipment, which is much more worry free and cost-effective than carbon adsorption equipment.

　　可能还有朋友会担心，膜用久了，处理效果会不会下降？其实大家完全不用操心，只要定期对设备做简单的检查和维护，比如清理设备管道、检查压力是否正常，膜的过滤、分离效果就不会下降，依然能稳定达到环保排放要求。而且膜结构设备的维护特别简单，不用专人负责，定期做基础检查就可以，大大节省了人力成本。

　　Perhaps some friends are worried that the treatment effect may decrease after using the film for a long time? In fact, everyone doesn't need to worry at all. As long as the equipment is regularly inspected and maintained, such as cleaning the equipment pipelines and checking whether the pressure is normal, the filtration and separation efficiency of the membrane will not decrease, and it can still stably meet environmental emission requirements. Moreover, the maintenance of membrane structure equipment is particularly simple, without the need for dedicated personnel. Regular basic inspections are sufficient, greatly saving labor costs.

　　再跟大家对比一下碳吸附设备和膜结构设备的使用寿命，就更能看出差距了。碳吸附设备的活性炭，一般用个1-2年就需要更换，不仅更换成本高，还得耽误设备运行；而膜结构设备的膜，使用寿命能达到8-10年甚至更久，只要正常使用，基本不用更换，长期下来，能节省一大笔设备维护和部件更换的费用。

　　By comparing the service life of carbon adsorption equipment and membrane structure equipment with everyone else, we can better see the gap. Activated carbon for carbon adsorption equipment usually needs to be replaced after 1-2 years, which not only incurs high replacement costs but also delays equipment operation; The membrane of membrane structure equipment can have a service life of 8-10 years or even longer. As long as it is used normally, it does not need to be replaced. In the long run, it can save a lot of equipment maintenance and component replacement costs.

　　总结一下，大家在选VOCs挥发气回收设备时，不用再担心膜的使用寿命问题。膜结构设备的膜，理论上可以长期使用，不会因处理VOCs挥发气分子而损坏，实际应用中，使用8年以上依然能达标运行是很常见的。而且相比传统的碳吸附设备，膜结构设备不仅使用寿命长，还能杜绝二次污染、确保排放达标、维护简单，不管是从环保合规角度，还是从运营成本角度，都是更靠谱的选择。

　　To summarize, when choosing VOCs volatile gas recovery equipment, there is no need to worry about the lifespan of the membrane. The membrane of membrane structure equipment can theoretically be used for a long time without being damaged due to the treatment of VOCs volatile gas molecules. In practical applications, it is common for it to operate at standard for more than 8 years. Moreover, compared to traditional carbon adsorption equipment, membrane structure equipment not only has a longer service life, but also eliminates secondary pollution, ensures emission standards, and is easy to maintain. Whether from the perspective of environmental compliance or operating costs, it is a more reliable choice.

　　现在国家对VOCs排放的要求越来越严，选对VOCs挥发气回收设备，既能顺利通过环保检查，又能省成本、少麻烦。膜结构设备凭借使用寿命长、处理效果稳定、维护简单等优势，已经成为主流选择。通过今天的讲解，相信大家已经搞懂了膜结构VOCs挥发气回收设备的使用寿命问题，也知道该怎么选择合适的设备了，你学会了吗？

　　Nowadays, the country's requirements for VOCs emissions are becoming increasingly strict. Choosing the right VOCs volatile gas recovery equipment can not only pass environmental inspections smoothly, but also save costs and reduce trouble. Membrane structure equipment has become the mainstream choice due to its long service life, stable treatment effect, and simple maintenance.
