一个沼气池不产气了,是怎么回事呢?追究它的原因,除发酵条件(温度、PH值、C/N)不当,输气管道和开关漏气外,主要是沼气池的漏气漏水。沼气池气密性的好坏是决定产气速度和贮气能力的关键,也是沼气事业能否推广的关键。为此,认真研究提高沼气池气密性的各种技术措施,势在必行。常见故障人们常把沼气池的壳体比喻成外胎,而把粉刷密封层比喻成内胎。壳体强度不够或粉刷层密封性能不好,均会出现渗漏而造成故障。病态池漏气漏水常见部位见图1。造成病态池的原因,主要是:(1)施工方面的原因,池基选择不当;施工工艺不符合要求,如水灰比不当;搅捣不实;养护不良;回填土不密实,粉刷质量差,压抹不实,各层间粘合不牢造成翘壳等。(2)材料方面的原因,建池材料质量不符合要求,配料不合理等。
A digester does not produce gas, what is going on? Investigate it for reasons, in addition to the fermentation conditions (temperature, PH value, C / N) improper, gas leaks and gas pipelines, the main gas pool leakage Leakage. Biogas digester air tightness is the key to determine the gas production rate and gas storage capacity, but also the key to whether the promotion of biogas projects. For this reason, it is imperative to seriously study various technical measures to improve the airtightness of digesters. Common faults People often metaphor of digesters hull shell, and the painted seal compared to the inner tube. Insufficient shell strength or paint layer sealing performance is not good, there will be leakage and cause failure. Sick pool leaking common parts shown in Figure 1. The causes of the pathological pool are mainly: (1) construction reasons, improper choice of pond base; construction technology does not meet the requirements, such as improper water-cement; stir up false; poor maintenance; backfill soil is not solid, poor quality paint, Unpredictable, non-binding between the layers resulting in Alice and so on. (2) The reason of material, the quality of built pool material does not meet the requirements, the ingredients are not reasonable and so on.
