在一些实施例中，强制循环蒸发系统还包括立式设置的输料管60，输料管60设于循环蒸发器20与强制循环泵50之间，输料管60为直管，输料管60沿竖直方向垂直循环蒸发器20及强制循环泵50设置，输料管60的入口与强制循环泵50的出口相连，输料管60的出口与循环蒸发器20的料液进口22相连。可以理解地，循环蒸发器20将热井40内的料液经输料管60输入至循环蒸发器20内。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
