Description

利用集气罩实现无动力自动搅拌的沼气发酵罐
技术领域
本实用新型涉及一种发酵罐，尤其涉及一种利用集气罩实现无动力自动搅拌的沼气发酵罐。
背景技术
以往的沼气发酵设备在运行中往往存在物料分布不均匀，发酵状态不好，产气少而且不均匀，容易出现结盖、挂壁等现象。
实用新型内容
为解决上述技术问题本实用新型提供一种利用集气罩实现无动力自动搅拌的沼气发酵罐，目的是使发酵正常进行，产气量高、产气持续性好，气量稳定，消除结盖挂壁现象。
为达上述目的本实用新型利用集气罩实现无动力自动搅拌的沼气发酵罐包括罐壁，在罐壁的上部设有集气罩，集气罩用支架固定在罐壁上。
所述集气罩为伞形气体集气罩。
所述的伞形气体集气罩上部为上排气口。
所述的上排气口顶部设有单向活门。
所述的集气罩与罐壁的距离为10-100cm。
本实用新型的优点效果：在发酵罐内增加一个集气罩，使其在产气过程中使其所产沼气集中从集气罩出口溢出，同时携带发酵液溢出，实现发酵过程中的自动搅拌，利用气体在集气罩中自然上升原理，发酵产生的沼气在通过安装在发酵罐上方的气体集气罩将沼气从集气罩顶端排气口排出，由于沼气通过排气口时有一定的速度，会带出一部分发酵液，使其形成位差，从排气口溢出沿集气罩外沿流向四周沿发酵罐内壁返回集气罩下方，如此反复使罐内发酵液一直处在搅拌中，进而使发酵正常进行，在不用外加动力即可以达到搅拌的目的，原料与微生物充分接触，其中有机物利用充分，污泥排放量显著减少，结盖或活性污泥沉淀失活等不正常发酵现象基本不再出现，结构简单、造价低廉、容易实现，产气效果好，运行平稳，同时又可节约能源，不失是一个一举多得的措施。
附图说明
图1是本实用新型的结构示意图。
图中1、上排气口；2、集气罩；3、单向活门；4、支架；5、罐壁。
具体实施方式
下面结合附图对本实用新型作进一步说明。
如图1所示本实用新型利用集气罩实现无动力自动搅拌的沼气发酵罐，包括罐壁5，在罐壁5的上部设有集气罩2，集气罩2用支架4固定在罐壁5上，集气罩2为伞形气体集气罩，伞形气体集气罩上部为上排气口1，上排气口顶部1设有单向活门3，集气罩4与罐壁的距离为10-100cm。
在发酵时首次加料与集气罩出口平齐后即可实现边产气边搅拌。
