以往所建的水压式沼气池,每当池内储气压力稍高时,活动盖与池体间的填料(多为湿粘土)就易遭冲动而漏气;活动盖也容易被掀动。一旦发生这样的情况,除浪费沼气外,有时还造成几日无气用。用户对此伤透脑筋,有的用层层叠叠压石防盖被掀;有的为防活动盖的缝隙填料漏气,索性用水泥浆敷死接口,不惜到换料时以钢钎慢慢凿开。为了解决这一问题,我们对活动盖作了改进。改进后的活动盖在储气达到40—50度时,也不会被掀动。活动盖与池体间的湿粘土严密结合,不易漏气,所以勿需压石或用水泥浆敷死接口,使用中起闭方便。图1是未改进前的活动盖结构,活动盖与池体
The built-in hydraulic biogas pool, whenever the reservoir pressure is slightly higher, the active cover and the pool between the filler (mostly wet clay) is vulnerable to impulse and leakage; removable cover is also easy to tilt. In the event of such a situation, in addition to waste biogas, sometimes also caused a few days without air. Users of this brain-wrestling, and some laminated with pressure stone anti-cover was lifted; some to prevent the activities of the gap filling packing leakage, simply die with cement slurry interface, hesitate to drill slowly chisel open. In order to solve this problem, we made improvements to the activities. Improved activities covered in the storage of gas reached 40-50 degrees, it will not be tilted. Active cover and the pool of wet clay closely integrated, not easy to leak, so do not need to pressure stone or cement mortar dead interface, the use of closed from the convenience.
