Description

热交换器、 包括该热交换器的能源回收装置及能源回收系统 技术领域
本发明涉及热交换器、包括该热交换器的能源回收装置及能源回 收系统， 特别涉及一种用于从流体中回收能源的热交换器、 包括该热 交换器的能源回收装置及能源回收系统。 背景技术
在日常生活中， 人们会使用不同洗涤设施进行清洁、 洗涤。 这些 设施包括， 例如， 浴室淋浴器、 洗涤槽、 洗头槽等。 但是， 如果这些 洗涤设施釆用热水作为洗涤介质 ,其所排放废水中通常仍含有大量热 能， 从而造成能源浪费。
一直以来，人们尝试釆用各种方法回收和利用这些白白流失的能 源。 例如， 美国专利 US4,304,292公开了一种放置于浴室的热回收装 置， 参照图 1A和 1B所示， 其热交换器包括由金属管屈曲成螺旋形 的热交换管 114a、 116, 其同心置于开设在基座 100的上表面 102的 螺旋形废水凹坑 104、 106 内， 淋浴产生的废水由地板 124a经通孔 128向下流并沿该螺旋形废水凹坑 104、 106流向中央排放口 108下 面的排水接头 110及排水管 112a, 冷水经水龙头管 56'从入水管 120 流经螺旋形热交换管 114a、 116 , 与热交换管外的废水进行热交换而 升温， 再经出水管 122a导出。 但是， 该热回收装置存在着以下问题
( 1 )热回收效率低：
( a ) 由于废水经单一条凹坑流向排水口， 该凹坑必须有足够空 间以供大量废水通过。 但当用水量少时， 废水量少， 废水只可淹浸热 交换管的底部， 热交换管只可于底部发挥其热交换功能， 故回收效率 有限；
( b ) 当用水量大时， 废水充满着整个凹坑， 但由于热交换管壁 及凹坑周壁的阻力， 大部分废水只于热交换管顶部的空隙以高速流 走， 而未能与热交换管内的冷水进行热交换。 加上水流的层流现象， 高速流走的热水并未有充分与热交换管壁邻近已被冷却的废水混合。 这都引致低回收效率；
( C ) 由于冷水经单一管道流向出口， 热交换管须有相当的内径 以足够供冷水通过。 但热交换只会于管壁进行， 由于管壁的阻力， 热 交换管中心的冷水会以较高速通过而未被充分加热。加上管中水流的 层流现象， 中心的冷水并未与管壁处已被加热的水充分混合， 也引致 低回收效率。
( 2 )须较长时间才可达致最高温度：冷水须要由热交换管的一 端流向另一端才能完成整个热交换过程， 但基于上述原因， 为了增加 热回收量， 该热交换管必须具备相当长度， 故冷水须较长时间才能达 到最高的稳定温度。
( 3 )该热交换管被屈曲盘绕成螺旋形， 但大部分浴室为方形， 故未能尽用浴室地面以作热交换。
( 4 )该热交换装置只适合安放于浴室， 并不适合安放于洗涤槽 等设施。 发明内容

本发明涉及一种热交换器以及包括该热交换器的用于从流体中 回收能源的能源回收装置。 上述流体可以是例如水等的液体， 也可以 是例如蒸汽等。 下面参照附图， 通过仅仅是举例方式描述本发明热交 换器与浴室的淋浴器以及洗涤设施的洗涤槽相结合的实施例。应当理 解， 本发明并不受其限制。
图 2 -图 5示出了本发明热交换器第一实施例的结构， 说明其结 合于浴室的淋浴器的情况。
如图 2 -图 4中所示， 热交换器 1安装于浴室基座 9, 其包括废 水收集器 11、 废水导流件 12及冷水导流件 13。
如图 3和图 4中所示， 废水收集器 11具有开口 111、 废水出口 112、空腔 113及多条半圓形的通道 114。废水导流件 12具有围边 122、 通孔 121、 设于底部的多条半圓形通道 123及平台 124。 冷水导流件 13具有冷水入口 131、 分流腔 132、 多条热交换管 133、 集流腔 134、 温水出口 135及位于热交换管 133内的条状阻流件 136。 条状阻流件 136的表面凸出形成有螺旋状的冷水导流墙 137 , 热交换管 133的外 壁凸出形成有螺旋状的废水导流墙 138。
图 5示出了热交换器 1的装配结构。 废水导流件 12平放于废水 收集器 11的开口 111内， 使废水收集器 11的多条半圓形通道 114与 废水导流件 12底部的多条半圓形通道 123共同形成多条通向废水出 口 112的圓形管道。 冷水导流件 13放置于空腔 113内， 使多条热交 换管 133与多条由上下半圓形通道 114及 123所形成的圓形管道基本 同心， 形成大致均匀的废水环状空间 141 , 包围着多条热交换管 133。 在装配时,废水收集器 11的各半圓形通道 114之间的间隔壁与废水导 流件 12底部的各半圓形通道 123之间的间隔壁相互之间可以留有间 隙,使得形成的各圓形管道互相连通。
使用时，冷水入口 131直接或间接地连接至建筑物的冷水源（图 中未示 ) , 温水出口 135连接至外部的加热器（图中未示 ) , 用以将 从温水出口 135导出的温水加热成为适温水，或者将温水出口 135连 接至浴室的水温及流量调节器（图中未示 ) , 用以使从温水出口 135 导出的温水与来自浴室的热水源（图中未示）的热水混合成为适温 水以供淋浴。 淋浴者站立于平台 124 上淋浴， 淋浴后的废水由平台 124收集后经通孔 121流入腔室 113 , 再流入多个废水环状空间 141 , 然后流向废水出口 112,并从废水收集器 11与浴室基座 9之间的间隙 142流向浴室排水口 91。 与此同时， 冷水从冷水入口 131导入冷水导 流件 13后， 经分流腔 132平行进入多条热交换管 133与条状阻流件 136之间的冷水环状空间 139, 并流向集流腔 134, 期间， 冷水与管 外以相反方向流过的热废水通过热交换管壁进行热交换，并被升温成 为温水。温水于集流腔 134汇集后于温水出口 135接驳至浴室的外部 装置中的加热器或水温及流量调节器（图中未示）以供淋浴。
废水流经废水环状空间 141时受阻于热交换管 133外壁凸出的螺 旋状的废水导流墙 138, —部分会沿螺旋状的废水导流墙 138螺旋前 进； 一部分会于该螺旋状的废水导流墙 138顶部与多条由上、 下半圓 形通道 114及 123所形成的圓形管道内壁之间的间隙 140直线前进， 两种水流互相干扰， 有效破坏废水的层流 (laminar flow), 使废水于前 进时能充分混合并作有效热交换。 此外， 该螺旋状的废水导流墙 138 也增加了热交换管 133的热交换面而增加热交换效率。
冷水流经冷水环状空间 139时， 受阻于从条状阻流件 136表面凸 出的螺旋状的冷水导流墙 137, —部分会沿螺旋状的冷水导流墙 137 螺旋前进， 一部分会于该螺旋状的冷水导流墙 137顶部与热交换管内 壁之间的间隙 142直线前进， 两种水流互相干 4尤， 有效地破坏冷水的 层流， 使冷水于前进时能充分混合并作有效热交换； 此外由于条状阻 流件 136 占据了热交换管中央大部分空间， 管中只残留了少量冷水， 淋浴时热交换器 1 能较快地达到稳定状态,减少调节水温时流失的清 水。
当使用一段时间后， 装置内难免积聚污垢， 影响能源回收效能， 使用者只须移开废水导流件 12就能清理内部污垢， 以保持高能源回 收效率。 使用者甚至可取出冷水导流件 13进行清洗。
上面参照附图清楚说明了本发明热交换器的一种实施例， 但是， 本发明并不受其限制。 例如， 图 4中所示的冷水导流件 13 只有八条 热交换管 133, 但实际上一个一平方米的浴室， 其地面便足以安放具 有数以拾计甚至上百条热交换管的热交换器。 此外， 所示热交换器 1 为一安装于浴室地面的外置件， 但其也可安装于浴缸底部或淋浴器 基座上或者与之构成一体。 此外， 所示热回收装置的热交换管为圓 形， 但为增加热交换面积， 其也可为长方形或多边形结构。
图 6-图 12示出了本发明热交换器第二实施例， 说明其结合于洗 涤设施的洗涤槽的情况。
如图 6中所示， 热交换器 2安装于洗涤槽 8及桌面 7底下， 并以 防水垫 31, 32 及紧固件 33固定。
如图 7和图 8中所示， 热交换器 2包括废水收集器 21、 废水导 流件 22、 冷水导流件 23(参见图 9-图 11)及废水连接器 24。 废水收 集器 21具有开口 211、 空腔 212、 废水出口 213及位于底部的 2个 通孔 214、 215。 废水导流件 22包括底座 223、 多条圓筒 222、 顶盖 221及手柄 224。 其中，圓筒 222由吹塑 (blow moulding)形成， 其内部 具有螺旋状的废水导流墙 225。 废水连接器 24具有空腔 241及废水 出口 242, 废水连接器 24用防水垫 243、 244及旋盖 245、 246固定 于废水收集器 21上。
如图 9至图 11中所示， 冷水导流件 23包括冷水入口 231、 分流 腔 232、 多条一端封闭的热交换管 233、 中空条状阻流件 236、 集流 腔 234及温水出口 235。 该多条热交换管 233的内壁凸出形成有螺旋 状的冷水导流墙 237。
废水导流件 22可拆卸地放置于废水收集器 21的空腔 212内，使 该多条内部有螺旋状的废水导流墙 225的圓筒 222于开口 211与废水 出口 213之间形成多条废水通道， 并且多条热交换管 233与多条内部 有螺旋状的废水导流墙 225的圓筒 222基本同心， 形成大致均勾的废 水环状空间 251 (参照图 12), 包围着多条热交换管 233。
图 12示出了热交换器 2的装配结构。 使用时， 冷水入口 231直 接或间接地连接至建筑物冷水源（图中未示）， 温水出口 235连接至外 部的加热器（图中未示），用以将从温水出口 235导出的温水加热成 为适温水，或者将温水出口 235连接至洗涤槽的水温及水量调节器 (图 中未示)， 用以使从温水出口 235导出的温水与来自洗涤槽热水源（图 中未示）的热水混合成适温水以供洗涤使用。 洗涤时产生的热废水流 经废水收集器开口 211后进入废水导流件 22再流入由该内部有螺旋 状的废水导流墙 225的圓筒 222与热交换管 233之间的废水环状空间 251流向废水出口 213, 进入废水连接件 24的空腔 241再从废水出口 242 连接至建筑物的排水管（图中未示）。 与此同时， 冷水从冷水入口 231导入冷水导流件 23后经分流腔 232平行进入多条热交换管 233 与中空条状阻流件 236之间的冷水环状空间 239向上流动至热交换管 233的封闭端， 再经中空条状阻流件 236中央的管道流向集流腔 234, 期间与热交换管 233 外以相反方向流过的热废水通过热交换管壁进 行热交换， 并被升温成温水。温水于集流腔 234汇集后于温水出口 235 接驳至外部的加热器（图中未示 )加热成为适温水，或者接驳至洗涤 槽的水温及水量调节器（图中未示）与热水混合成适温水以供使用。
废水流经废水环状空间 251时受阻于螺旋筒 222的螺旋状的废水 导流墙 225, —部分会沿螺旋状的废水导流墙 225螺旋前进， 一部分 会沿螺旋状的废水导流墙 225顶部与热交换管 236之间的间隙 252直 线前进， 两种水流互相干扰， 有效地破坏废水的层流， 使废水于前进 时能充分混合， 并作有效热交换。
冷水流经冷水环状空间 239时受阻于热交换管 233内壁的螺旋状 的冷水导流墙 237, —部分会沿螺旋状的冷水导流墙 237 螺旋前进， 一部分会沿该螺旋状的冷水导流墙 237与中空条状阻流件 236之间的 间隙 238直线前进， 两种水流互相干扰有效破坏冷水的层流使冷水前 进时能充分混合并作有效热交换。此外该螺旋状的废水导流墙 237也 增加了热交换管 233的热交换面以增加热交换效率。
为免温水于中空条状阻流件 236中央流向集流腔 234时与中空条 状阻流件 236外未完全被升温的冷水进行不必要的热交换，该中空条 状阻流件 236可用良好热绝缘体如塑胶制造，或由良好绝缘体如中空 的双壁结构形成。
当使用一段时间后， 装置内难免积聚污垢， 影响热回收效能， 使 用者只须拿着手柄 224, 就能把整个废水导流件 22取出， 用清水冲 洗或用长柄圓形小刷子清理螺旋筒 222内的污垢，以保持高热回收效 率。 由于螺旋筒 222 内的螺旋状的废水导流墙 225 包围着热交换管 236, 特别是其最底部的一至两圈螺旋状的废水导流墙部分 255被设 计成紧套着热交换管 233 , 取出废水导流件 22时热交换管 233上的 污垢会一并被刮走， 无须刻意清理。
上面结合附图清楚说明了本发明热交换器的第二种实施例， 但 是， 本发明并不受其限制。 例如图中所示的冷水导流件 23只有 4条 热交换管 236 , 但以现时通用于发廊的洗发槽为例， 其中心去水孔径 约为 85毫米,放置于其内的热交换器 2足可容纳数拾条热交换管 233。 此外所示热交换器为一安装于洗涤槽底部的外置件，但只要稍加改变 其也可安装于浴室或与洗涤槽或浴室构成一体。此外由于该中空条状 阻流件 236占据了热交换管中央大部分空间，管中央只残留了少量冷 水， 使用时该热交换器能较快地达到稳定状态， 减少调节水温时流失 的清水。
图 13-图 17示出了本发明热交换器第三实施例， 说明其结合于洗 涤设施的洗涤槽的情况。
如图 13中所示， 热交换器 4安装于洗涤槽 8及桌面 7底下， 并 以防水垫 32 及紧固件 33固定。
如图 14中所示， 热交换器 4包括废水收集器 41、冷水导流件 43 及废水连接器 44。 废水收集器 41具有开口 411、 空腔 412及废水 出口 413。 废水连接器 44用防水垫 443及旋盖 446固定于废水收集 器 41上。
如图 15及图 16中所示，冷水导流件 43包括冷水入口 431、分流 腔 432、 多条一端封闭的热交换管 433、 多条中空条状阻流件 436、 集流腔 434及温水出口 435。 热交换管 433的一端封闭， 另一端与分 流腔 434连通。 条状阻流件 436为中空， 其内部形成管道， 各条条状 阻流件 436分别置于各条热交换管 433内，与热交换管 433的内壁之 间构成第二流体环状空间 439(见图 17), 条状阻流件 436的中空管道 的一端于邻近热交换管 433的封闭端与第二流体环状空间 439连通， 另一端与分流腔 434连通。 在第二流体环状空间 439内， 与第一或第 二实施例的结构相似，该多条中空条状阻流件 436的外壁或该多条热 交换管 433的内壁可具有螺旋状的冷水导流墙（图中未示）， 以增加 热交换效率。 如图 15及图 16中所示， 各条热交换管 433之间形成有 大致均匀的间隙 437。与第一实施例的结构相似，该多条热交换管 433 的外壁可设有螺旋状导流墙（图中未示）， 以增加热交换效率。
图 17示出了热交换器 4的装配结构。使用时， 冷水入口 431直接 或间接地连接至建筑物冷水源（图中未示）， 温水出口 435连接至外部 的加热器（图中未示），用以将从温水出口 435导出的温水加热成为 适温水， 或者将温水出口 435连接至洗涤槽的水温及水量调节器 (图 中未示),用以使从温水出口 435导出的温水与来自洗涤槽热水源（图中 未示）的热水混合成适温水以供洗涤使用。 洗涤时产生的热废水流经 废水收集器开口 411后进入各热交换管 433之间的大致均匀的间隙 437 ,或进入由多条热交换管 433与废水收集器 41的内壁所形成的大 致均匀的间隙 438 ,流向废水出口 413, 进入废水连接器 44的空腔 441 再从废水出口 442连接至建筑物的排水管（图中未示)。 与此同时， 冷 水从冷水入口 431导入冷水导流件 43后经分流腔 432平行进入多条 热交换管 43与中空条状阻流件 436之间的冷水环状空间 439向上流 动至热交换管 433的封闭端， 再经中空条状阻流件 436中央的管道流 向集流腔 434, 期间与热交换管 433外以相反方向流过的热废水通过 热交换管壁进行热交换， 并被升温成温水。 温水于集流腔 434汇集后 于温水出口 435接驳至外部的加热器（图中未示）加热成为适温水， 或者接驳至洗涤槽的水温及水量调节器（图中未示）与热水混合成 适温水以供使用。
