Description

带太阳能跨季节蓄热设施的沼气池
技术领域
本实用新型涉及带太阳能跨季节蓄热设施的沼气池。
背景技术
沼气池可以提供优质的生物质能沼气，有利于节能减排。但沼气池需要持续提供35℃以上的热能。现有的一种跨季节土壤储存太阳热能系统，通过开挖土壤、在土壤中设置土工布蓄水池、在蓄水池上面设置护板并覆土构成。其造价较高。
发明内容
本实用新型的目的是要提供带太阳能跨季节蓄热设施的沼气池。
本实用新型解决其技术问题所采取的技术方案：用太阳能集热装置、多井土壤换热设施和沼气池，组成一个带太阳能跨季节蓄热设施的沼气池。多井土壤换热设施由一个筒状母井和若干个与母井连接的子井组成。在母井井壁上设置多个子井井口并连接多个子井；子井的封闭端伸入地下。子井含有通向其封闭端的输水管；用子井、输水管、与各输水管连通的输水干道、循环泵、沼气加热装置和太阳能集热装置组成一个水路回路。
本实用新型的有益效果：多井土壤换热设施建造、改造和拆除方便、可以在既有沼气池下的土壤中设置建造；子井井管不容易损坏可靠性高、对环境友好、多井水路回路换热热阻低，其施工费用只有开挖建造的太阳能跨季节蓄热设施的40％。只要伸长子井长度或者增加增加数目就可以扩大蓄热的土壤范围。通过储存太阳能提高了太阳能设施的利用率。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1是一个带太阳能跨季节蓄热设施的沼气池结构示意图。
图中1.土壤；2.母井；3.子井；4.封闭端；5.输水管；6.输水干道；7.循环泵；8.沼气加热装置；9.集热装置；10.水路回路；11.开口端；12.阀门组；13.沼气池。
具体实施方式
图1给出本实用新型的一个实施例。
图1中，在一个置于土壤1中的筒状母井2井壁上设置子多个子井3井口并连接多个子井3，组成一个多井土壤换热设施。子井3封闭端4伸入地下。子井3含有通向其封闭端4的输水管5。用子井3、输水管5、与各输水管5连通的输水干道6、循环泵7、沼气加热装置8和太阳能集热装置9组成一个水路回路10。进入输水管5的水在输水管5开口端11处流出，并从子井3内部与输水管5之间的夹层返回母井2，在返回途中通过子井3井壁与土壤1换热，使土壤1的温度改变。
图1实施例用筒状母井和子井组成的多井土壤换热设施，及其与太阳能集热装置、沼气池一起构成的带太阳能跨季节蓄热设施的沼气池的工作原理：通过切换阀门组12，令太阳能集热装置9串接于水路回路10、沼气加热装置8关断，太阳热能进入土壤1使土壤1升温。实现用土壤储存太阳能。通过切换阀门组12关断太阳能集热装置9、沼气加热装置8接通水路回路10，土壤1中储存的热能通过水路回路10供应沼气池13。
