Description
技术领域 technical field
本实用新型属于秸秆沼气池处理装置领域，特别是一种大型秸秆沼气池的防结壳装置。The utility model belongs to the field of processing devices for straw biogas pools, in particular to an anti-crust device for large straw biogas pools.
背景技术 Background technique
当前推广使用的秸秆沼气池是在沼液中直接投入秸秆，然后在无氧条件下发酵产气，但是在使用的过程中，秸秆会从沼液中飘浮起来，在沼气池的上部形成一层小透气的硬壳，这样大量秸秆结壳的结果会造成沼气池产出的沼气不能被正常收集使用，影响沼气池的正常运行。The currently promoted straw biogas digesters put straw directly into the biogas slurry, and then ferment and produce gas under anaerobic conditions. Small air-permeable hard shell, such a large amount of straw crusting will cause the biogas produced by the biogas digester to be unable to be collected and used normally, affecting the normal operation of the biogas digester.
