据介绍，沼气中含有60%以上的甲烷，而汽车天然气甲烷含量在90%以上
It is reported that biogas contains more than 60% methane, while the methane content of automobile natural gas is more than 90%
沼气储气柜在实际使用中将配备安全水封配件，以在储罐超压时为合理的压力释放做准备。发生超压时，气体将通过水封排出，同时会混入大量的水。随着水蒸气的状态，水位将逐渐降低以达到泄压的目的。如果双膜储气柜的风量较大，则会直接喷水，但这会导致保护器无法自行恢复，因此需要手动装满水。
The biogas gas holder will be equipped with safety water seal accessories in actual use to prepare for reasonable pressure release in case of overpressure of the storage tank. In case of overpressure, the gas will be discharged through the water seal and mixed with a large amount of water. With the state of water vapor, the water level will gradually decrease to achieve the purpose of pressure relief. If the air volume of the double membrane gasholder is large, it will spray water directly, but this will cause the protector to not recover by itself, so it needs to be filled with water manually.
一些制造商的沼气储气柜没有特殊的内膜保护系统，而仅使用超压水封进行保护。在正常操作下，外膜可以抵消内膜的压力，但是当外膜出乎意料地发生故障时，或者由于电力系统无法及时提供压力时，内膜会过压，并且超压容易泄漏。如果内膜泄漏，则外膜和外膜将形成混合气体。非常危险因此，气罐的水封通常填充有防冻剂以应对寒冷季节地区。
Some manufacturers do not have special inner membrane protection system for biogas gas storage cabinets, but only use overpressure water seal for protection. Under normal operation, the outer membrane can counteract the pressure of the inner membrane, but when the outer membrane fails unexpectedly or the power system cannot provide pressure in time, the inner membrane will overpressure and the overpressure is easy to leak. If the inner membrane leaks, the outer membrane and the outer membrane will form a gas mixture. Very dangerous, so the water seal of the air tank is usually filled with antifreeze to deal with cold season areas.
1、储气罐的材料选择非常重要。材料的质量决定了整个储气罐的质量和寿命。通常，选择具有强拉伸强度，抗腐蚀，抗紫外线以及耐酸和碱的氟化物材料，并非所有的含氟或涂氟材料都是合适的。必须使用特殊的复合材料以确保使用寿命。通常，使用具有良好的柔韧性，强的拉伸强度，紧凑的复合材料，良好的气密性和防腐性的材料。
1. The material selection of air storage tank is very important. The quality of materials determines the quality and service life of the whole air storage tank. Generally, fluoride materials with strong tensile strength, corrosion resistance, UV resistance and acid and alkali resistance are not suitable for all fluorine-containing or fluorine-coated materials. Special composite materials must be used to ensure service life. Generally, materials with good flexibility, strong tensile strength, compact composites, good air tightness and corrosion resistance are used.
2、材料的抗老化性能很好，但物理性能很差，很容易损坏。不太的人看不到一般性损坏，但是将来使用寿命会受到影响。因此，需要更多的人员来进行制作和安装，并且在制作和安装过程中应使材料的特性更加清晰。高品质只能通过避免容易引起的质量问题来实现。该材料的设计寿命通常为15年。
2, the anti-aging properties of materials are very good, but their physical properties are very poor, so they are easy to damage. Less professional people can't see the general damage, but the service life will be affected in the future. Therefore, more professionals are needed for fabrication and installation, and the characteristics of materials should be clearer in the process of fabrication and installation. High quality can only be achieved by avoiding easily caused quality problems. The design life of this material is usually 15 years.
3、由于双膜气体保持器的正常运行在压力下，因此控制和保护装置在实际工作中尤为重要。特别是当它用作反应器顶部和盖子的集成设备时。一方面，所使用的材料或制造工艺不符合相应的要求，另一方面，这是由于相关保护措施不足所致。因此，在使用时必须使用高精度和可靠的安全保护装置。
3. Since the normal operation of the double film gas holder is under pressure, the control and protection device is particularly important in practical work. Especially when it is used as an integrated device for the top and cover of the reactor. On the one hand, the materials or manufacturing processes used do not meet the corresponding requirements, on the other hand, this is due to the lack of relevant protective measures. Therefore, high-precision and reliable safety protection devices must be used.
4、目前，沼气储气柜有自己的控制方法。它可以自动解决一些问题，从而减轻用户的压力。除了材料，控制和保护设备，制造过程以及维护外，以后的使用也是极大地影响其使用寿命的因素。毕竟，储气柜并不像家用电器那样智能，只要插上电源就可以使用。使用它们时，对用户进行技术培训非常重要。实际上，通过用户的初步判断可以避免许多故障。
4. At present, the biogas gas holder has its own control method. It can automatically solve some problems, so as to reduce the pressure of users. In addition to materials, control and protection equipment, manufacturing process and maintenance, future use is also a factor that greatly affects its service life. After all, the gas conservator is not as smart as household appliances. It can be used as long as the power is plugged in. When using them, technical training for users is very important. In fact, many faults can be avoided through the user's preliminary judgment.
