Description

寒冷地区增保温叁层膜式沼气池
所属技术领域
本发明涉及一种寒冷地区增保温叁层膜式沼气池，是一种利用太阳能对循环水集热加温或其它能源对循环水加温，有保温隔热层可实现自动恒温控制高效产沼气的软体沼气池。适合畜禽粪便、农作物秸秆产沼气等的综合利用，属环境工程所需设备装置。
背景技术
贯彻科学发展观，实现人与自然和谐发展，拓展资源再生利用，促进生物质能的科学利用，保护生态环境，努力构建生态绿色和谐家园，优化整合社会资源，推动科技、畜禽养殖事业又好又快发展。党中央、国务院已将大力发展推广沼气工作列入发展规划和新农村建设。
沼气作为一种新型的再生能源，正是一种对生物质能的有效利用，但目前没有得到很好的利用。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、不迅速等缺陷。
发明内容
为了更好的实现对粪污的综合处理，及废弃的有机物进行有效利用，本发明提供了一种寒冷地区增保温叁层膜式沼气池，它利用太阳能对循环水集热加温或其它能源对循环水加温，有保温隔热层，可实现自动恒温控制高效产沼气的软体沼气池。实现本发明的具体技术方案为：一种沼气发生装置，沼气池体有叁层膜构成，以高弹力增强橡塑尼龙布为基材，最外层以保温隔热材料填充，中间层为加热装置：内设扁型可循环加热盘管(内为循环水)，内层与粪污接触表面设计为梯形褶皱，梯形表面为凹凸相间的圆柱小体，为发酵菌床，用于发酵菌着床。沼气池上设有进料管、出料管、循环加热盘管进出口、沼气出气管、温度探头等组成。本发明沼气池可实现工厂化、机械化生产，多道工序各部件集成一体，有利于推广；可实现：1、系统中的发酵液可实现恒温(35℃左右)发酵，温度可实现自动调整控制；2、沼气池内层与粪污接触表面设计为梯形褶皱，梯形表面为凹凸相间的圆柱小体，用于发酵菌着床，为发酵菌提供适宜的环境，从而提高发酵效率、反应速度，提高产气量；3、系统可实现高效率低能耗。本发明为增保温叁层膜式沼气池，内层发酵菌床、中层为循环热水加热装置、外层保温隔热，大幅度降低系统能量损失，从而实现高效率低能耗；4、系统为软体沼气池，发酵的不同阶段压力不同，从而避免了池内结壳，。
本发明结构合理，运行高效，适合广大北方农牧区，可利用本装置对养殖场及人粪便等粪污进行高效发酵处理产生沼气，沼气作为一种新的能源，不仅节约了资源，而且净化了环境，实现可持续发展。

具体实施方式
如图所示的是一种寒冷地区增保温叁层膜式沼气池。沼气池壳体1由叁层膜构成，以高弹力增强橡塑尼龙布为基材，经多道工序合成而成，最外层10以保温隔热材料填充，中间层9为加热装置：内设扁型可循环加热盘管(内为循环热水)，内层8与粪污接触表面设计为梯形褶皱，梯形表面为凹凸相间的圆柱小体，为发酵菌床，用于发酵菌着床。所述的7进料管和2出料管以及5沼气出气管由PVC材料制成，4循环加热盘管进出口材料由市售特种聚氯乙烯材料制成，3温度探头为市售普通探头，本发明沼气池具有耐腐蚀、增保温、高效率、使用寿命长等特点。具体实施方式为：将本发明沼气池安装于地下2.5米处，裸露在外的管道要作保温处理。安装好后，将调整好浓度的粪污通过进料管7打入沼气池壳体1内，打入的料液以不超过发酵液液面6为界限，此时温度探头3显示温度低于35℃，太阳能或其它能源即对循环水加温，热水从盘管进出口4打入壳体膜中层(加热装置)9中进行对料液的循环加热，这时壳体膜外层(保温隔热层)10起到保温降低系统能量损耗的作用，壳体膜内层(发酵菌床)8最先得到热量，立即吸引发酵菌着床发酵从而产生新的能量，通过不断热循环使温度达到35℃，沼气大量生成通过沼气出气管5向用户输送。当料液温度高于系统设定值时，如55℃，温度探头3显示温度，太阳能(或其它能源)热水循环系统自动停止对料液的循环加热。经过发酵后，沼渣、沼液可通过出料管2运出，可用于农业生产。
