为什么会出现负压?产生负压的原因是:第一,大量出料时速度太快,使池内压力突然下降。第二,沼气池的气箱不漏气,但发酵间或进出料间的中、下部漏水较严重,而造成负压。为什么有的沼气池气压表水柱较高,但燃烧不久火力便迅速减弱,甚至熄火?气压表水住位置的高
Why negative pressure occurs? Negative pressure is due to the reasons: First, a large number of discharge speed too fast, so that a sudden pressure drop in the pool. Second, the digester gas box does not leak, but between the fermentation room or between the material in the lower part of the more serious leakage, resulting in negative pressure. Why some of the digester barometer water column higher, but soon after the fire burned rapidly weakened, or even turn off? Barometer water table location high
