Description

大型连体式沼气发酵装置
技术领域：
本实用新型属于一种沼气装置，特别涉及一种集发酵、储气于一体的大型连体式沼气发酵装置。
背景技术：
沼气作为一种可再生能源，不仅清洁、廉价、卫生而且在发展生态农业及环境保护和综合利用等诸多方面逐渐显示出其独特的优越性，受到人们的高度重视。但是现有的沼气装置存在如下缺陷：1、在沼气池和沼气燃具之间需要连接对沼气进行净化处理和压力调节的设备，如脱硫器、压力表等，安装这些设备需要的管道附件多、占用的空间大、并且操作、管理和维修都不太方便。2、在使用时沼气的压力不稳定，给用户带来不便。3、产气量低，一般在100立方左右。4、发酵池没有保温装置，冬季的产气率更低。5、由于采用混凝土浇筑的整体结构，施工效率低，无法进行工业化大规模制造，从而严重地制约了沼气的普及和推广。
发明内容：
本实用新型的目的就在于克服上述现有技术中存在的不足，而提供一种大型连体式沼气发酵装置，该装置集发酵、储气于一体，结构紧凑、产气量大、沼气压力稳定，且可工业化大规模生产。
本实用新型的技术方案是：一种大型连体式沼气发酵装置，包括进料口、出液口和出渣口，其特征在于：由外壳、安装在外壳内的产气室和套在产气室外的储气浮罩组成；外壳和产气室之间是水层；产气室内装有沼气搅拌装置，储气浮罩底部装有配重块。
上述沼气搅拌装置由主轴、安装在主轴上的搅拌叶片和与主轴连接的电机组成。
上述外壳外部设有保温层和吸热层。
上述储气浮罩上装有放气装置。
本实用新型具有如下的优点和积极效果：
1、由于集发酵、储气于一体，因此结构紧凑、占用的空间小、并且操作、管理和维修方便。
2、由于在外壳和产气室之间是水层，因此可有效地防止产气室内的沼气泄露，使用安全、可靠。
3、当从产气室进入储气浮罩内的沼气逐渐增多时，储气浮罩内的压力逐渐增大，为了防止储气浮罩上升，在储气浮罩的底部装有配重块，使储气浮罩和配重块的重量恒定，保证储气浮罩内的沼气压力稳定。并且本设计还在储气浮罩上装有放气装置，从而可进一步保证沼气压力的稳定和储气浮罩的安全，为用户使用带来方便。
4、由于在外壳外部分别设有保温层和吸热层，因此既可大量地吸收外界的热量，使发酵更加充分，又可进行保温，从而保证冬季的产气量。
5、由于在产气室内装有搅拌装置，因此可使原料充分发酵，提高产气量。
6、本设计由于使用钢材制作，因此可以进行工业化大规模生产，便于沼气的推广使用。
附图说明：
图1是本实用新型的主视图。
图2是本实用新型的剖面图。
具体实施方式：
如图所示：一种大型连体式沼气发酵装置，由外壳1、安装在外壳内的产气室2和套在产气室外的储气浮罩3组成。为了使原料充分发酵，提高产气量，产气室内装有由主轴4、安装在主轴上的搅拌叶片5和与主轴连接的电机6组成的沼气搅拌装置。为了防止产气室内的沼气泄露，在外壳和产气室之间装有水7。为了防止储气浮罩内沼气过多、压力过大，在储气浮罩上底部装有配重块8和放气阀9。为了保证冬季的产气量，在外壳外部设有保温层10和吸热层11。上述储气浮罩的正面设有进料口12、后面设有出液口13和出渣口14，储气浮罩的顶部装有压力表15和放气口16。
