　　哈喽，家人们好啊！快过年了，很多做沼气、生物脱硫相关的朋友，还在琢磨设备的连接和使用问题——毕竟过年期间设备也不能停，要是连接不当、接口搞不清，出现堵塞、漏水漏汽的情况，既耽误生产，还得费心维修，影响过年心情。今天就继续给大家做知识分享，不聊复杂术语，纯实操干货，重点讲一讲生物脱硫中，脱水罐和脱硫罐的连接方式，还有各个接口的实用功能，一步步讲清楚、说明白，看完大家自己就能核对设备连接，轻松避开故障坑。

　　Hello, family! It's almost the Chinese New Year, and many friends who work in biogas and biological desulfurization are still pondering about the connection and use of equipment - after all, equipment cannot be stopped during the Chinese New Year. If the connection is improper, the interface cannot be clarified, and there are blockages, water leaks, and steam leaks, it will not only delay production, but also require costly maintenance, affecting the mood of the Chinese New Year. Today, I will continue to share knowledge with you. Without discussing complex terms, I will focus on practical practical knowledge. I will talk about the connection methods between dehydration tanks and desulfurization tanks in biological desulfurization, as well as the practical functions of each interface. Step by step, I will explain them clearly and clearly. After reading, you can check the equipment connection by yourself and easily avoid the fault pit.

　　先跟大家说个大前提，生物脱硫的核心环节，离不开脱水罐和脱硫罐的配合——沼气先经过脱水罐除水，再进入脱硫罐去除硫化氢，两步到位，才能保证沼气纯度，适配发动机发电等后续使用，而两者的连接方式和接口使用，直接决定了脱硫效果和设备稳定性，大家一定要重点关注。

　　First of all, let me share a major premise with you. The core process of biological desulfurization cannot be separated from the cooperation between the dehydration tank and the desulfurization tank. Biogas first goes through the dehydration tank to remove water, and then enters the desulfurization tank to remove hydrogen sulfide. This two-step process is necessary to ensure the purity of biogas and adapt it to subsequent use such as engine power generation. The connection method and interface use of the two directly determine the desulfurization effect and equipment stability, and everyone must pay close attention to it.

　　咱们先从气体流向和核心连接说起，这是最基础、也最关键的一步，记准流向，就不会接反管道。沼气不管是从黑膜沼气池过来，还是直接从沼气罐出来，第一步都要先进入脱水罐——先脱水，再脱硫，这个顺序千万不能乱，不然沼气里的大量水分会影响脱硫剂效果，还容易导致脱硫罐堵塞、板结。

　　Let's start with the gas flow direction and core connection, which is the most fundamental and crucial step. By accurately recording the flow direction, we will not connect the pipeline in reverse. Whether biogas comes from the black film biogas digester or comes directly from the biogas tank, the first step is to first enter the dehydration tank - dehydration first, followed by desulfurization. This sequence must not be chaotic, otherwise the large amount of water in the biogas will affect the effectiveness of the desulfurizer and easily lead to blockage and compaction of the desulfurization tank.

　　具体来说，脱水罐的水管是从上端接入，水会从这里喷洒下来，而沼气则从另一侧的进气口进入，正常的气体流向是向下走，顺着管道进入后续的脱硫罐。这里给大家标清楚两个关键接口：脱水罐和脱硫罐上都有两个进气口，对应连接管道，确保沼气顺畅流通；而两个罐体的上端，都有专门的出气口，脱硫罐的出气口，就是直接通往发动机的方向，输送经过脱水、脱硫后的干净沼气，保障发动机正常运行。

　　Specifically, the water pipe of the dehydration tank is connected from the upper end, and water will spray down from here, while biogas enters from the inlet on the other side. The normal gas flow direction is downward and enters the subsequent desulfurization tank through the pipeline. Here are two key interfaces clearly marked for everyone: there are two air inlets on both the dehydration tank and the desulfurization tank, which correspond to the connecting pipes to ensure smooth flow of biogas; The upper ends of both tanks have dedicated air outlets. The outlet of the desulfurization tank is directly connected to the direction of the engine, delivering clean biogas that has been dehydrated and desulfurized to ensure the normal operation of the engine.

　　讲完核心连接和流向，再跟大家说说几个容易被忽略，但特别实用的接口和管线，尤其是过年期间设备无人值守，这些接口能帮大家快速判断故障、减少麻烦。首先重点说一下旁通管线，就是我们设备上专门预留的那一条备用管线，平时这个旁通阀是关闭状态，大家不用管它。

　　After discussing the core connections and flow, let me talk about a few interfaces and pipelines that are often overlooked but are particularly practical, especially during the Chinese New Year when the equipment is unmanned. These interfaces can help you quickly diagnose faults and reduce trouble. First of all, let's focus on the bypass pipeline, which is the spare pipeline specially reserved on our equipment. Normally, this bypass valve is in the closed state, so you don't need to worry about it.

　　那旁通管线什么时候用呢？关键时刻能救急！比如过年期间，脱硫罐出现脱硫剂板结、管道阻塞的情况，沼气流通不畅，我们就可以打开旁通阀，通过它来判断故障——如果打开旁通后，气体流通正常，就说明是脱硫罐本身堵了，针对性处理就行，不用盲目拆卸整个设备，省时又省力，避免耽误生产。而且旁通阀平时关闭，能保证所有沼气都经过完整的脱水、脱硫流程，确保进入发动机的沼气成分稳定、纯度达标。

　　When will the bypass pipeline be used? Can provide emergency assistance at critical moments! For example, during the Chinese New Year, if the desulfurizer in the desulfurization tank becomes clogged and the pipeline is blocked, and the biogas flow is not smooth, we can open the bypass valve to determine the fault. If the gas flow is normal after opening the bypass, it means that the desulfurization tank itself is blocked. Targeted treatment is enough, without blindly disassembling the entire equipment, which saves time and effort and avoids delaying production. Moreover, the bypass valve is usually closed to ensure that all biogas undergoes a complete dehydration and desulfurization process, ensuring that the composition of the biogas entering the engine is stable and the purity meets the standard.

　　接下来是罐体上的仪表接口，每一个罐体的顶上，都预留了装正压表的接口，而罐体侧面还留了接负压表的接口，这两个接口都是用来检测设备运行状态的，特别实用。比如如果罐体内出现堵塞，负压表和正压表的数值就会出现异常，我们通过仪表就能快速判断，不用拆开罐体检查，既方便又安全，尤其适合过年期间远程简单排查故障。

　　Next is the instrument interface on the tank body. On the top of each tank body, there is a reserved interface for installing a positive pressure gauge, and on the side of the tank body, there is also a reserved interface for connecting a negative pressure gauge. Both interfaces are used to detect the operating status of the equipment, which is particularly practical. For example, if there is a blockage inside the tank, the values of the negative pressure gauge and positive pressure gauge will be abnormal. We can quickly judge through the instrument without opening the tank for inspection, which is convenient and safe, especially suitable for remote simple troubleshooting during the Chinese New Year.

　　然后是罐体下端的两个关键接口，大家别搞混了。第一个是放水口，因为沼气里都是饱和湿气，含有大量水分，经过脱水罐后，水分会沉淀在罐体底部，这些水分需要及时排放，不然会影响脱水效果，还可能腐蚀罐体，所以平时要定期检查，及时放水，过年期间可以提前检查排放，避免积水结冰损坏设备。

　　Then there are two key interfaces at the bottom of the tank, don't confuse them. The first one is the water outlet, because biogas is saturated with moisture and contains a large amount of water. After passing through the dehydration tank, the water will settle at the bottom of the tank. These water contents need to be discharged in a timely manner, otherwise it will affect the dehydration effect and may corrode the tank. Therefore, regular inspections should be carried out regularly and water should be drained in a timely manner. During the Chinese New Year, the discharge can be checked in advance to avoid equipment damage caused by water accumulation and freezing.

　　第二个是出料口，这个是脱硫罐专属的接口，位于脱硫罐下端，打开这个接口，就能把里面失效的脱硫剂取出来，方便更换；而脱硫罐的上端，还有一个对应的进料口，新的脱硫剂，就是从这个进料口添加进去的，更换起来很便捷，大家自己就能操作，不用请专业师傅，节省维修成本。

　　The second one is the discharge port, which is a dedicated interface for the desulfurization tank located at the bottom of the tank. By opening this interface, the expired desulfurizer inside can be removed for easy replacement; At the upper end of the desulfurization tank, there is also a corresponding feeding port. The new desulfurizer is added from this feeding port, which is very convenient to replace. Everyone can operate it themselves without hiring a professional technician, saving maintenance costs.

　　这里再跟大家重申几个关键注意点，避免大家用的时候出错：一是气体流向不能反，必须先过脱水罐，再过脱硫罐；二是旁通阀平时一定要关闭，只有故障排查时才能打开，防止未脱硫的沼气直接进入发动机，影响设备寿命；三是定期放水、检查仪表数值，尤其是过年期间，提前做好检查，避免设备出故障。

　　Here we would like to reiterate a few key points to avoid mistakes when using: firstly, the gas flow direction cannot be reversed, it must first pass through the dehydration tank and then the desulfurization tank; Secondly, the bypass valve must be closed regularly and can only be opened during troubleshooting to prevent undissolved biogas from directly entering the engine and affecting equipment life; The third is to regularly release water and check instrument values, especially during the Chinese New Year period, to conduct inspections in advance and avoid equipment malfunctions.

　　可能有人会问，这套连接方式，适合所有生物脱硫场景吗？其实不管是小型黑膜沼气池，还是中型沼气生产项目，这套脱水罐+脱硫罐的连接方式都适用，接口设计合理，操作简单，实用性很强，而且适配发动机发电，刚好满足大家的生产需求，过年期间正常使用完全没问题。

　　Some people may ask, is this connection method suitable for all biological desulfurization scenarios? In fact, whether it is a small black film biogas digester or a medium-sized biogas production project, the connection method of this dehydration tank+desulfurization tank is applicable. The interface design is reasonable, the operation is simple, the practicality is strong, and it is suitable for engine power generation, which just meets everyone's production needs. It can be used normally during the Chinese New Year without any problems.
