除了产气不足,病池的多发症是“三漏气”,即:活动盖板漏气;进、出料管漏气;输气管道漏气和压力损失大。其解决办法简述于下。一、活动盖板漏气原因:目前设计的盖板属逆向力盖板。沼气池产气阶段池中有内压力,产气少压力小,盖板问题不大。但当产气量大时,压力逐渐增大,封盖的泥巴收缩,时间一长,逆向力盖板出现了漏气现象,由小变大。解决的办法:在调查中发现东乡县虎圩乡周家村建池户周若群同志在县农能站协助下,采用顺向力盖板(亦称反盖),从池内往上盖,符合内力内挡,
In addition to the lack of gas production, the morbidity of the sick pool is “triple-leaked”, namely: leaky cover of the movable cover; leakage of gas into and out of the material pipe; large leakage and pressure loss of the gas transmission pipeline. The solution is outlined below. First, the activities cover leak reasons: the current design of the cover is a negative force cover. Biogas production phase of the pool has internal pressure, less gas less pressure, cover little problem. However, when the gas production is large, the pressure gradually increases, the cover of the mud shrank over time, the reverse cover leakage phenomenon, from small to large. The solution: In the survey found that Zhouxiang County, Tiger Township, Dongxiang County, built pool Chihou Zhou Comrades at the county Nongon station with the help of the force of the cover (also known as anti-cover), from the pool to cover, in line with internal forces block,
