Description

秸秆沼气站
技术领域
本实用新型涉及再生能源设备领域，更具体地说，是涉及一种环保高效的秸秆沼气站。
背景技术
现有的多是利用畜禽粪便生产沼气，这样的沼气生产受粪便和地区的限制很大。长期以来，由于秸秆木质纤维素含量较高、不易被厌氧消化、发酵产气量低以及密度小、体积大、不具有流动性等理化性质，所以秸秆一直都未能大规模用于沼气的生产。
实用新型内容
本实用新型所要解决的技术问题是，克服现有技术中存在的不足，提供一种环保高效的秸秆沼气站。
本实用新型秸秆沼气站，通过下述技术方案予以实现，包括依次连接的原料池、上料罐和发酵罐；所述上料罐通过气体管道分别连接提料储罐和出料储罐，提料储罐设置真空泵，出料储罐设置加压泵；发酵罐顶部通过产气管道连接分离净化装置；设置压缩机的沼气管道分别连接分离净化装置和沼气储罐。
本实用新型所述原料池内设置搅拌机。所述发酵罐内设置加热装置，发酵罐外周设置保温装置。所述发酵罐底部通过液体管路连接至原料池。所述气体管道、产气管道和沼气管道分别设置阀门。
本实用新型可实现秸秆的机械化进、出料，解决了秸秆发酵传热、发酵效率低的问题。本实用新型完全以秸秆为原料生产沼气，使沼气的生产，不再受粪便和地区的限制。厌氧发酵罐是秸秆沼气的核心部分，厌氧发酵罐布料均匀，新进入的料液通过喷淋搅拌的作用很快于发酵罐内的发酵液混合，达到快速、充分接种的作用。本实用新型不仅加速产气率，而且解决了池体结壳、进出料难得问题，产气后的沼液、沼渣可用作有机肥。
附图说明
图1是本实用新型结构示意图。
具体实施方式
下面结合附图对本实用新型做进一步描述。
如图1所示，本实用新型包括依次连接的原料池1、上料罐2和发酵罐3；所述原料池内设置搅拌机4；所述上料罐通过气体管道分别连接提料储罐5和出料储罐6，提料储罐设置真空泵7，出料储罐设置加压泵8；发酵罐顶部通过产气管道连接分离净化装置9；所述发酵罐内设置加热装置，发酵罐外周设置保温装置；所述发酵罐底部通过液体管路连接至原料池；设置压缩机10的沼气管道分别连接分离净化装置和沼气储罐11。所述气体管道、产气管道和沼气管道分别设置阀门。
本实用新型工作原理如下：将粉碎后的秸秆投入原料池，利用发酵罐底部的液体管路将发酵液送至原料池，通过搅拌机搅拌均匀后，打开提料储罐的真空泵将原料液抽提至上料罐，然后关闭真空泵及其管道，打开出料储罐的加压泵，将上料罐中的原料液从发酵罐顶部喷淋洒入，发酵后产生的沼气通过产气管道送至分离净化装置，然后经过沼气管道中的压缩机将沼气加压并储存在沼气储罐中，最后通过减压装置送到用户。
上面所述的实施例仅仅是对本实用新型优选实施方式进行描述，并非对本实用新型的构思和范围进行限定，在不脱离本实用新型设计思想的前提下，本领域中普通工程技术人员对本实用新型的技术方案作出的各种变形和改进，均应属于本实用新型的保护范围。
