Description

可利用有机肥发酵热能的沼气发生装置
技术领域
本发明涉及一种可利用有机肥发酵热能的沼气发生装置。
背景技术
近年来，我国沼气事业获得了迅速的发展，特别是在农村地区，由于沼气能源分布广泛，凡是有生物的地方都有可能获得制取沼气的原料，因此沼气是一种取之不尽，用之不竭的再生能源。在我国农村的广大地区修建沼气池，不仅可以解决农村的燃料和照明问题，还可以利用沼气发电作为脱粒、加工食料、饲料和制茶等的动力能源。此外，人、畜的粪便以及各种作物秸杆、杂草等，通过发酵后，既产生了沼气，还可作为肥料，而且由于腐熟程度高使肥效更高，粪便等沼气原料经过发酵后，绝大部分寄生虫卵被杀死，可以改善农村卫生条件，减少疾病的传染。现在，沼气的应用正在各国广大农村推广，沼气能源的开发利用的普及等方面，已经取得了较好的成绩。
沼气发酵是通过微生物的生命活动，对发酵原料中的有机物进行分解，进而产生沼气的过程。微生物的生命活动要求有适宜的环境条件，C/N比、浓度、密封度、温度、酸碱度、氧化还原势及其它各种环境因素对它们都有一定的影响。而在影响沼气发酵的各种因素中，温度的变化对产气量的影响尤为明显，从某种意义上来说，温度是产气的关键。在一定温度范围内，温度越高，产气率越高，产气量越大。一般来说沼气细菌在10～60℃范围内都能进行发酵，但低于20℃后沼气发酵明显减慢，低于10℃发酵停止。我国农村中的沼气池大都在自然温度下进行发酵，发酵温度随气温和季节而变化，一旦到了冬季，特别是在我国的北方地区，沼气池温偏低，导致产气很少甚至不产气，无法达到正常的供气要求。为了提高沼气池温度，使沼气池正常产气，人们也采取了一些措施，如添加温热性粪料，增设风障，秸秆覆盖保温，覆盖塑料大棚等等，但往往保温效果不佳，仍无法达到正常产气的温度要求。
我们知道，有机肥在发酵时会产生大量的热量，而一般情况下，这些发酵热都是直接排出而并没有加以利用，如果能将有机肥发酵热引到沼气池的发酵环境周围，这就能够提高沼气池的温度，从而为沼气发酵提供适宜的温度条件，从而保证沼气池在冬季的正常产气。
发明内容
本发明的目的是提供一种可利用有机肥发酵热能的沼气发生装置，该沼气装置可以利用有机肥发酵热提高沼气池温度，以保证沼气池的正常产气。
本发明的目的是这样实现的：这种可利用有机肥发酵热能的沼气发生装置，包括设于地下的沼气池，所述沼气池上方设置有有机肥发酵室。
本发明的显著特点是将沼气池建造在有机肥堆料发酵室内，利用有机肥发酵产生的热能来提高环境温度，以满足沼气池正常产气的温度要求，减小了季节变化对沼气池发酵的影响。
此外，本发明的大棚式或房屋式有机肥堆包发酵室不仅发酵效果好，而且结构简单，造价低，包袋生产成本低，运输方便，进一步提高了该沼气装置的实际使用效果和经济性。
附图说明
图1是本发明实施例的构造示意图。
图2是图1的A-A剖视图。
具体实施方式
本发明的可利用有机肥发酵热能的沼气发生装置，包括设于地下的沼气池1，所述沼气池1上方设置有有机肥堆料发酵室2。
上述有机肥堆料发酵室2为大棚式或房屋式有机肥堆包发酵室，所述大棚式或房屋式有机肥堆包发酵室内设有堆包架3，所述堆包架3上间隔放置有装满有机肥发酵原料的包袋4，所述包袋4为可透气包装袋。
为了排出雾气，上述有机肥堆料发酵室2的上侧设有排风管道5和抽风机6。
上述沼气池1的进料口7和水压间8均设于有机肥堆料发酵室2内。
有机肥物料经过搅拌混合达到有机肥的制造要求，装入可透气的包装袋，用推车运输到大棚发酵间，叠加在悬空的(可通气)的木架或预制板上，当发酵温度上升到60-70度左右，发酵间雾气比较大，开启发酵间上侧的抽风机，多余的雾气经排风管道排出，从而保证有机肥的正常堆肥制造。
