Description
所属技术领域
本发明涉及一种寒冷地区沼气池增保温方法,特别涉及一种利用地暖管(或其它暖水管)循环热水加温,从而使沼气池增温的方法。属于沼气池增保温技术领域。适合畜禽粪便、农作物秸秆产沼气等的综合利用,属环境工程所需增保温设备装置。
背景技术
沼气作为一种新型的再生能源,是对生物质能的有效利用,但目前没有得到很好的推广。现有的传统沼气池不能很好的解决高寒地区沼气的冬季生产问题,占地面积大,成本高、利用率低、发酵不完全,一年只有半年好用,对粪污的处理不彻底、不迅速,使得人们对沼气池失去信心不愿意建池。料液发酵产沼气最佳温度为35-55℃,此时效率是较高的,而北方大部分地区大部分时间达不到上述要求,造成沼气生产效率低下,资源浪费严重,综合效益不高。从长远来看沼气池的增保温问题,已经成为制约我国北方地区尤其寒冷地区沼气发展的重要因素之一。
发明内容
本发明涉及一种寒冷地区沼气池增保温方法,特别涉及一种利用地暖管(或其它暖水管)循环热水加温,从而使沼气池增温的方法。它是由三部分构成,一是:沼气池建在地下(深度可根据当地冻土层厚度决定),四周用防水卷材做防水处理;二是:在此基础上使用发泡水泥、EPS聚苯板(或聚氨酯建筑保温材料)做保温层处理;三是:在做好防水保温的基础上利用地暖管(或其它暖水管)循环热水加温,从而使沼气池增温。具体方法为:对传统沼气池(包括砖砌、砖混、全混凝土结构沼气池及软体沼气池防护墙)将地暖管砌入混凝土内(具体施工可参照有关地暖工程相关标准,对底部施工可使用钢筋混凝土),地暖管(或其它暖水管)可在沼气池的底部及四周,也可整个沼气池网状结构铺设地暖盘管(或其它暖水管)然后砌入混凝土中;对软体沼气池可先在其底部及四周将铺设好的地暖管(或其它暖水管)砌入混凝土中,然后在其上面放入软体沼气池。为了更好的实现对沼气池的增保温及高效率的生产沼气,本发明提供了一种寒冷地区沼气池增保温方法,特别涉及一种利用地暖管(或其它暖水管)循环热水加温,从而使沼气池增温的方法。它有保温隔热层,可以利用太阳能、生物质能以及其它能源对地暖管(或其它暖水管)循环水集热加温,也可安装自动恒温控制系统,实现恒温高效产沼气。本发明可实现:1、寒冷地区沼气池的增温保温,冬季也能高效产沼气;2、系统中的发酵液可实现温控发酵;3、有利于寒冷地区沼气新能源事业的推广;4、解决了寒冷地区冬季畜禽粪便废水的处理。
本发明具有结构新颖,实用性强,操作方便运行高效等优点,适应于大、中、小型沼气池的增保温,特别适合广大北方寒冷农牧区。
