Description

一种拼接式的保温沼气罐
所属技术领域：
本发明是一种拼接式的保温沼气罐，沼气罐由上下罐体拼接而成，罐体由内层、保温层及外层组成。
背景技术：
沼气是国家大力扶持的新能源产业，沼气对解决农村日常能源问题，环境保护问题起着至关重要的作用，发展农村沼气是我国的长期基本国策。
沼气的生成需要一定的环境条件，沼气生成需要在一定的温度、密闭、厌氧、潮湿、酸碱度适中的环境中，尤其是温度是沼气生成的关键条件。目前国内广的北方地区和一部分南方地区，冬天寒冷，滴水成冰，很多地区一到冬天沼气罐无法产气，甚至冻结。这为沼气的普及和使用造成了极大的困难。另外，沼气池的工业化生产和安装运输也一直是难题。
本发明为一种拼接式的保温沼气罐，解决了上述问题。在保温层的问题上，为保证保温效果，保温层要具有良好的隔热保温性能，同时保温层和内层、外层一样须具有良好的抗渗、防水特性；保温层还承受沼气罐罐体及罐内料浆的巨大压强。这些要求保温材料要具有良好的保温性能、相当的抗压强度和防渗、抗水特性，为达到上述要求，本方明采用无机发泡材料作为罐体的保温材料。采用拼接式罐体和无机发泡材料有利于工业化生产，便于运输安装，大幅降低了成本、生产难度和对环境的污染。
发明内容：
本发明为一种拼接式的保温沼气罐，这种沼气罐具有良好的保温性能、结构强度、防渗抗水特性，可在低温下产气，且结构及制造工艺简单、成本低，利于工业化生产。
本发明为解决其技术问题所采用的技术方案是：一种带保温层的沼气罐，沼气罐分为上下罐体，上下罐体采用预置法兰盘螺栓连接及胶接，上罐体顶端预置进出料口，进出料口顶端预埋螺母，密封盖与进出料口采用螺栓连接，密封盖设有气嘴及泄压模块。罐体分为内层、温层和外层。本发明为一种拼接式的保温沼气罐。
附图说明：
附图为本发明结构及位置关系示意图，图1为局部剖面主视图。
附图1中，1.气嘴及泄压模块，2、密封盖，3、上罐体，4、下罐体，5、内层，6、保温材料层，7、外层。
具体实施方式：
下面结合说明书附图对实施例加以详述。本发明为球形或圆柱形罐体，由上罐体(2)和下罐体(3)拼接而成，上下罐体采用预置法兰盘螺栓连接及胶接，上罐体设进出料口，保证进出料方便；进出料口与密封盖采用螺栓紧固连接，保证罐体的密封性；密封盖设有气嘴及泄压模块(1)，保证对外供气和罐体内沼气压力不超过安全范围；罐体分为内层(5)、保温层(6)、外层(7)，保证罐体的保温、结构强度、抗水防渗的性能；其中内层和外层为纤维增强复合材料或无机材料，保温层为无机发泡保温材料。密封盖结构与罐体相同也分为内层、保温层和外层，保证罐体的保温性能。
本发明是保证低温下产生沼气的拼接式保温沼气罐，本发明便于工业化生产、便于运输、安装及维护，而且使用简便，便于操作。
本发明的有益效果：
1、保证了低温下沼气的连续生成与供气，为北方及南方低温地区沼气的普及打开了新的方向。
2、保证了沼气罐工业化生产的可行性，降低了生产成本，方便了安装、运输，便于维护。
