Description

料液循环流化发酵装置
技术领域
本发明属于沼气能源领域，具体涉及一种料液循环流化发酵装置。
背景技术
发酵生产沼气是一项实用工程技术，利用厌氧发酵，处理农牧业废弃物、生活污水、生产废水等，同时产生优质清洁的生物质能源——沼气（主要成分为甲烷），兼具环保、能源、节能减排等多方面效益。但传统的沼气工程采用静态发酵工艺，发酵效率低下，产气率和污染物去除率都不高，严重制约产业发展。近年来，动态发酵技术得到一定程度的推广，并逐渐成为沼气工程的主流工艺形式。但现有动态发酵装置对流场形态的设计缺乏优化，发酵料液没有形成完整的循环流化通路，导致料液流化效率低下，物料混合不够均匀，有效发酵容积小。搅拌流场不均衡，容易使发酵原料形成底部堆积或顶部结壳，导致酸化等不良现象，发酵效率低下。一些较差的流场设计还容易造成物料的堵塞，损坏设备。
发明内容
本发明的目的是为了克服现有沼气动态发酵装置流场形态的设计缺乏优化，发酵原料形成底部堆积或顶部结壳，导致发酵效率低下的缺陷，为人们提供一种发酵效率高，消耗动力少，不易堵塞的料液循环流化发酵装置。
本发明的目的是通过下述技术方案来实现的。
本发明的料液循环流化发酵装置，其特征在于所述料液循环流化发酵装置由发酵罐1和水泵7组成，发酵罐1上部为储气间2，储气间2下面为发酵间3；发酵罐1顶部设置有导气管11和带密封塞9的进料口8；发酵罐1底部设置有水泵出水口6，水泵出水口6与水泵7连接，水泵7进水口与循环管4连接；循环管进口5设置在发酵间3上部的四周；发酵罐1下侧部设置有检修口10。
本发明在发酵罐四周设置循环管，通过水泵实现料液循环流化。其工作过程如下：
初始发酵料液从顶部进料口进入发酵罐，料液漫过循环管高度，留下小部分空间作为储气间。然后启动水泵，使发酵料液从循环管进口沿循环管进入水泵，从水泵出水口以设定速度进入发酵间，形成竖直向上的水流。发酵料液再从循环管流出，回到水泵的入口，通过水泵重新进入发酵间，形成一个闭式循环系统。该循环系统在内部形成流化，打破静态发酵，极大地提高了发酵料液的混合均匀性，大幅度提高了产气率并避免了料液结壳、堵塞等问题。
综上所述，本发明克服了现有沼气动态发酵装置流场形态的设计缺乏优化，发酵原料形成底部堆积或顶部结壳，导致发酵效率低下的缺陷，提供的料液循环流化发酵装置发酵效率高，消耗动力少，不易堵塞。
