Description

一种保温沼气罐
技术领域:
本实用新型涉及一种收集、发酵气体装置,特别是一种保温沼气罐。
背景技术:
沼气由于可将农业废气的秸秆变为清洁能源和有机肥料,尤其在农村正在普及和推广。现行推广使用的沼气池为地埋式水泥池,这种地埋式方式虽然具有一定的保温作用,但由于设置有进、出料口,在北方的冬季,气温低产气不足,严重影响沼气池使用效果。专利号为200520024209.8的一种长效保温沼气罐,为了解决此问题,采取了罐体加保温层并在罐体外的下部设置加热管等措施,虽然有改善,然而由于罐体有补充进料口和溢流口,仍然受环境温度的影响,尽管可用加热的办法克服,但需消耗能量且结构复杂造价较高。
发明内容:
本实用新型的目的是提供一种保温沼气罐,这种沼气罐在寒冷季节仍能正常产生沼气,且结构简单不需消耗热能。本实用新型的技术方案是,一种保温沼气罐,包括有罐体和保温层,其特征在于:罐体顶部设有一个进出料口,法兰密封盖与上述进出料口的法兰密封连接,法兰密封盖上设有出气管与沼气设备连接。所述保温层为聚氨酯发泡层或者珍珠岩层。法兰密封盖上还设有安全阀。所述罐体为分体式密封连接结构。本实用新型与现有技术比较具有保温性能好,在寒冷季节能正常产气且结构简单价格较低的优点。
附图说明:
附图是本实用新型保温沼气罐局部剖面的主视图。
具体实施方式:
结合附图对本实用新型作详细说明,这种沼气罐为球形罐体1,罐体由内层2和外层4以及中间的保温3构成,内层和外层可用玻璃钢制作,保温层可以是聚氨酯发泡层,也可在内外层间填充珍珠岩或者其他保温材料。由于此沼气罐在地面上使用,罐体的形状也可以是具有美感的植物形、动物形或者其他形状。为了便于制作、运输和安装,罐体为分体结构,组装时,将其对好后用玻璃胶粘接而成。在罐体的顶部设有一投料和出料口,法兰盖5通过螺栓与罐体口法兰密封连接,法兰盖上设有出气管6与用沼气设备连接,法兰盖上也可设置安全阀用来防止罐内沼气超压。

Claims (4)

1、一种保温沼气罐,包括有罐体和保温层,其特征在于:罐体顶部设有一个进出料口,法兰密封盖与上述进出料口的法兰密封连接,法兰密封盖上设有出气管与沼气设备连接。
2、如权利要求1所述的一种保温沼气罐,其特征在于:所述保温层为聚氨酯发泡层或者珍珠岩层。
3、如权利要求1所述的一种保温沼气罐,其特征在于:法兰密封盖上还设有安全阀。
4、如权利要求1所述的一种保温沼气罐,其特征在于:所述罐体为分体式密封连接结构。
