Description
技术领域
本实用新型涉及可燃气体发生装置，尤其是一种球形沼气罐装置。
背景技术
目前我国农村所用的沼气池一般埋在地下，砖混结构，容积大，采用水料混合的湿法发酵，产气慢，气压不稳定，混凝土结构易造成漏气漏水，冬天气温低时难以正常产气，建沼气池及维修费用成本高，安装使用麻烦，出渣困难，需经常加料，不定时地对池内的原料进行搅拌才能正常产气，由于是固定建于地下，费工费力，不易普及推广；另一种类型是球形沼气罐，它由上罐体、下罐体、密封组合安装，外接储气罐和太阳能集热装置，罐体采用玻璃钢材料制作。上罐体设有进料口、出气管，该罐强度高、重量轻、耐腐蚀、不易漏气、使用方便，但其总体造价较高，上、下罐体密封后连接不牢固，下罐体底部为球形，稳定性差。
发明内容
本实用新型的目的是提供一种保温效果好、产气量大，连接牢固，造价低的球形沼气罐装置。
所述球形沼气罐装置包括上罐体1、下罐体2、出气管道3与上罐体1密封连接的出气管道3上串联设置有安全阀4、控制阀5，其特征是：上、下罐体1、2外侧分别复合有保温层6，在保温层6外侧涂有吸热层7。上罐体1和下罐体2分别设置有连接法兰盘8，法兰盘通过螺栓固定连接。下罐体2下部制成一圆截面平面9。
本实用新型的有益效果是：1、上下罐体外侧不仅复合有保温层，而且在保温层外侧还涂有吸热层，具有较好的保温效果，罐体可直接放置于地面上使用，罐内适用于湿法或干法发酵技术，罐内发酵温度有明显提高，产气量大，干法发酵每次投单一草料可产气持续6个月左右；2、上、下罐体密封后，还采用法兰盘固定连接，机械强度大大提高；3、下罐体底部为一圆截面平面，稳定性更强；4、结构简单、制作成本低，安装运输方便，适用于中小城镇，广大农村家庭使用。
附图说明
图1是本实用新型结构示意图，
图中：1-上罐体，2-下罐体，3-出气管道，4-安全阀，5-控制阀，6-保温层，7-吸热层，8-法兰盘，9-圆截面平面。
具体实施方式
下面结合附图对本实用新型进一步说明：如图1中，所述球形沼气罐装置，包括上罐体1、下罐体2、出气管道3与上罐体1密封连接的出气管道3上串联设置有安全阀4、控制阀5，其特征是：上、下罐体1、2外侧分别复合有保温层6，在保温层6外侧涂有吸热层7。上罐体1和下罐体2分别设置有连接法兰盘8，法兰盘通过螺栓固定连接。下罐体2下部制成一圆截面平面9。
罐体可用玻璃钢或其它材料制成，罐体外侧复合的保温层的厚度可根据南北地区不同选择，安装时，上下罐体密封后，用螺栓连接法兰盘。本实用新型球形沼气罐装置的使用方法与普通球形罐基本相同。
