阿尔胡斯附近的哈梅尔的沼气植物现在可以将其最新水箱视为丹麦最大的甘油坦克。它在由持久的不锈钢制成的完全绝缘的消化器中含有4.500m³甘油。
The tank
The project is part of an existing biogas plant with a power of two Megawatt. The diameter of the new biogas tank is 25 m with a height of almost 9 m. It is constructed with stainless steel shell plates in a segment-like design. At the height of almost 9 m, seven rings of the shell plates are necessary. The lower five rings are made from stainless steel 1.4462 and the upper two rings from stainless steel 1.4571 to prevent from corrosion。
The roof
消化器上有一个不锈钢屋顶，上央支撑。外环由内部和外部拧紧的元件组成，连接到储罐的顶部，而内环则呈更高。因此，下降10°。屋顶设计用于绝缘和覆层。它通过两个检查开口完成。
The accessories
配备了加热系统和完整的绝缘材料，它具有消化器的基本配件。此外，丹麦最大的甘油罐有两个燃气密度的墙壁衬套，两个带梯子的工作平台和三名不锈钢的强大潜水运动搅拌器。
The substance glycerin
发酵过程的基础是甘油，pH值在3,5到8之间。这是生物柴油生产中的废物。甘油的密度为1,3 kg/L，加热至52°。甘油被认为是发酵过程中最有价值的输入，因为细菌几乎转化了所有甘油。因此，几乎没有发酵残基。玉米和甘油的输出之间的比较说明了甘油的能量值。一般指导水平说，一吨玉米的产量为200-250立方米，而甘油的产量为1.000立方米。
The construction
The most crucial part of the project was the construction phase due to the enormous size of the tank. After the assembly of the first ring including the roof, the whole digester was electrically lifted up. 37 pillars were used to lift up the first ring and another four we needed to lift up the central support as well. Then the second ring was assembled and the tank was lifted several times until the seventh ring was constructed.
The reason why
It was a simple decision explains the plant owner. We have decided for stainless steel because it is the most durable material in terms of corrosion. And the decision for Stallkamp was easy as well. With the experienced and reliable distribution partner Biogas Teknik A/S, we knew that this project would going to be a success.
