Description

一种液体动力自动搅拌沼气发酵装置
发明名称
一种液体动力自动搅拌沼气发酵装置
技术领域
本发明涉及环境保护与资源再利用领域，具体地涉及到一种液体动力自动搅拌沼气发酵装置。
背景技术
在沼气发酵装置中设置搅拌装置改善发酵过程的传质传热效率，以缩短发酵周期，提高沼气中甲烷的含量和发酵基质的利用率。目前采用的搅拌装置有四类：其一是通过循环水泵对发酵基质进行混合的液体搅拌装置；其二是利用电力驱动的机械搅拌装置；其三是以压缩的沼气作为搅拌动力的气体搅拌装置；其四是利用沼气在特别设计的发酵罐中产生的压力驱动的料液液力自动搅拌装置。
用泵驱动的液体搅拌装置耗电量大、设备可靠性不高且搅拌效果不甚好。机械搅拌装置虽然比较实用，技术也很成熟，但其能耗大、故障率高且维修困难。以压缩沼气为动力的搅拌装置常因压力不足或工艺缺陷等因素产生管道堵塞等故障，而且要用沼气压缩机压缩的沼气进行搅拌，因此能耗高、设备故障率也很高。本发明揭示的液体动力自动搅拌沼气发酵装置就是一种利用沼气在特别设计的发酵罐中产生的压力驱动的发酵液液力自动搅拌装置。该装置结构简单、维护方便、经久耐用、无能耗、传质传热效果良好，从而使沼气发酵过程高效地运行。本发明的内容和发酵罐液力自动搅拌的工作原理
本发明揭示了一种由内、外双罐结构组成的发酵罐。此种发酵罐的内罐高度的一半设置在外罐内部，另一半凸出于外罐之上端。外罐的容积为内罐容积的四到六倍。内罐的下端距离外罐底部约10至100cm，并设置有按流体力学原理设计的导流罩。外罐的上端设置有与内罐的上端连通的管道，并安装有受“可编程逻辑控制器”(以下简称PLC)控制的电磁阀。内罐的上端还设置有沼气和沼液的排放管道。利用该罐的上述特殊结构和对电磁阀的逻辑控制，使发酵过程产生的绝大部分沼气聚集在外罐的上部。当设置在内外罐上端连通管道上的电磁阀处于关闭状态，内罐上端的沼气和沼液排放管道处于开通状态时，聚集在外罐上部的沼气产生压力将外罐中的发酵液从内罐的下端压入内罐，从而实现外罐沼液向内罐的自动注入。当内罐中的发酵液液面上升至设定位置时，用于发酵的新鲜料液从设置在外罐上端的进料口注入。与此同时，发酵后的沼液经设置在内罐上端的沼液排出管道流出。待新鲜料液注入过程结束时，设置在内外罐上端连通管道上的电磁阀自动打开。外罐上端聚集的沼气迅速排入内罐上端，促使内罐上部的沼液迅速下降，并以冲击流的形式从内罐下端排入到外罐底部，从而实现内外罐中沼液的又一次自动交换。当内外罐中的发酵液液面达到同一水平面时，设置在内外罐上端连通管道上的电磁阀自动关闭。发酵过程进入下一个液体动力自动搅拌过程。
