Abstract

本实用新型公开了一种用于小型沼气罐的沼气储存循环装置，其特征是，它是在沼气罐上端的出气管上安装单向出气阀、安全排气阀、集水器、储气囊和三通，三通的一个口连接炉灶，三通的另一个口连接循环泵，循环泵出口连接到沼气罐底部。本实用新型的优点是：罐内气压大时，由气囊储存多余液体，在单向阀的作用下不会再向罐内反充，大于一定压力时才从安全排气阀少量排出，通过循环泵使气囊气体从罐底进入，实现气体自动搅拌，防止原料结壳，形成沼气周而复始的良好循环。

Description

用于小型沼气罐的沼气储存循环装置
技术领域
本实用新型涉及一种沼气罐利用装置，尤其涉及10m3以下的小沼气罐。
背景技术
目前，传统沼气罐存在着以下不足，当沼气充足时往往导致料液在高压气体压力下流出池外，必须及时排气才能解决，排气不及时容易涨坏沼气池，排出的气体又是影响大气环境的有害气体。另外，现有的沼气罐内容易结垢。
发明内容
本实用新型的目的在于克服现有小型沼气罐存在的不足之处，提供一种结构简单的沼气循环装置。
为了达到上述目的，本实用新型采用的技术方案是：在沼气罐上端的出气管上安装单向出气阀、安全排气阀、集水器、储气囊和三通，三通的一个口连接炉灶，三通的另一个口连接循环泵，循环泵出口连接到沼气罐底部。
本实用新型的优点是：
罐内气压大时，由气囊储存多余液体，在单向阀的作用下不会再向罐内反充，大于一定压力时才从安全排气阀少量排出，通过循环泵使气囊气体从罐底进入，实现气体自动搅拌，防止原料结壳，形成沼气周而复始的良好循环。
附图说明
图例是本实用新型结构示意图。
图中：1-沼气罐，2-单向出气阀，3-安全排气阀，4-集水器，5-储气囊，6-三通，7-炉灶，8-循环泵。
具体实施方式
下面结合附图对本实用新型的实施作进一步详细概述。
由图1可知，本实用新型是在沼气罐1上端的出气管上安装单向出气阀2，单向出气阀2连接安全排气阀3，通过集水器4通向储气囊5，再利用三通6连通炉灶7，三通6的另一出口通过循环泵8气体又循环到沼气罐1内。
本实用新型在管道最低处安装集水器4，在炉灶燃烧时，沼气供炉灶，在不燃烧时，沼气又循环到沼气罐内，能够促使料液流动，防止结壳，使料液分布均匀，增强微生物与原料的接触，使其活性增强，提高产气量，提高原料的利用率和能量的转换效率。该沼气装置平均提高产气量20％以上，有效利用沼气提高10％以上。
