Abstract

带太阳能跨季节蓄热设施和热泵的沼气池，由太阳能集热装置、热泵机组、多井土壤换热设施和沼气池组成，多井土壤换热设施由母井和子井组成，其特征在于含有由子井、输水管、输水干道、循环泵、沼气加热装置、太阳能集热装置和热泵机组组成的水路回路；所述子井含有通向其封闭端的输水管。本实用新型的有益效果：多井土壤换热设施建造和改造方便、可以在既有沼气池下的土壤中设置建造；子井不容易损坏可靠性高、对环境友好、冬季土壤换热设施换热热阻低。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。使用热泵可利用较低温度的土壤蓄热。结合附图给出一个实施例。

Description

带太阳能跨季节蓄热设施和热泵的沼气池
技术领域
本实用新型涉及带太阳能跨季节蓄热设施和热泵的沼气池。
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。
发明内容
本实用新型的目的是要带太阳能跨季节蓄热设施和热泵的沼气池。
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、热泵机组、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和热泵的沼气池。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、输水干道、循环泵、沼气加热装置、太阳能集热装置和热泵机组组成一个水路回路。
本实用新型的有益效果：多井土壤换热设施建造和改造方便、可以在既有沼气池下的土壤中设置建造；子井不容易损坏可靠性高、对环境友好、冬季土壤换热设施换热热阻低。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。使用热泵可利用较低温度的土壤蓄热。
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和热泵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.热泵机组；11.水路回路；12.开口端；13.阀门组；14.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、太阳能集热装置9和热泵机组10组成一个水路回路11。进入输水管5的水在输水管5开口端12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实施例工作原理：通过切换阀门组13，令太阳能集热装置9接通水路回路11、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13关断太阳能集热装置9、接通沼气加热装置8水路回路11，使土壤1中储存的热能通过水路回路10供应沼气池14。当土壤温度过低时，启用热泵机组10提升多井换热设施所提供的热能温度供应沼气池14。
