一、密封沼气池活动盖的简便方法有的农户在使用沼气的过程中,往往因封不住活动盖而造成沼气池漏气,影响正常婕用。我们在实践中摸索到一种密封沼气池活动盖的简便方法(适用于按国标GB4750—84建造的平饭式活动盖,见图1),即使在池内压力1000毫米水柱(即9807帕斯卡)的情况下,也不会漏气。其方法如下:1.密封材料沼气池活动盖的常用密封材料有粘土、白干泥、水泥、石灰等。先将不含砂的于粘土锤碎,筛去粗粒和杂物,按1∶1—15的配比(重量比),将水泥与粘土干拌均匀后,分成大、小两堆料,再加水拌和,将小堆料拌成泥浆状,将大堆料拌
A simple way to seal the cover of biogas activities Some farmers in the process of using biogas, biofuges are often leaked due to cover activities can not cover, affecting the normal Jie use. In practice, we found a simple way to seal the cover of biogas digesters (applicable to the flat-type movable lid constructed according to national standard GB4750-84, see Figure 1). Even at a pressure of 1000 mm of water (9807 Pascal) Case, it will not leak. The method is as follows: 1. Sealing material Commonly used sealing materials for digester cover clay, white dry mud, cement, lime and so on. The first non-sand clay crushed, sieved to the coarse particles and debris, according to the ratio of 1: 1-15 (weight ratio), the cement and clay dry mix evenly, divided into large and small two stacks, Add water to mix, the small pile mix muddy, will be a lot of material mix
