Description

一种空气净化方法 技术领域
本发明涉及一种空气净化方法。 通过将高楼表面湿化, 即利用众 多并立流水吸附空气中悬浮颗粒物。 吸附有颗粒物并溶解有害气体的 水流下后汇集于位于地面的集水槽, 并通过过滤设备过滤供循环使 用。
背景技术
为了净化空气减少空气中的悬浮颗粒物, 通常采用的方法有铺设 覆盖路面来减少扬尘面积, 对烟尘排放和汽车尾气排放进行治理来减 少污染物的排放量, 利用喷水池、 洒水车、 或人工降雨等手段进行降 尘。 虽然增加植草种树的面积可以有效地净化空气, 但城市发展所导 致的绿地面积减少、 燃料使用量的增加, 使上述各种措施收效甚微。 因此空气的净化主要还是靠天然自净。
林木茂盛的山区, 悬浮颗粒物的产生量少。 既使有从城区被风吹 来的颗粒物, 除了自然的尘降和雨雪净化外, 还有一种自净方式, 就 是利用地势和迎风向的植被, 粉尘易被吸附于潮湿的草木上, 难以再 次腾起。
山区中众多山峰多呈锥状竖立, 其表面又竖立着众多柱状林木。 这种自然形态与风力作用下的动态含尘空气接触。 具有水湿性的吸附 力的林木表面将浮尘沉集。 或者浮尘因水气的浸透作用结团并且重量 增加而落于地表。 由此使污染的空气在一定程度上实现自净。
随着对城市的不断开发, 城中绿地面积逐渐减少, 绿地面积所占 比例降低。 因而树木自净空气的效果减弱。 环境和空气质量日呈恶化。 因此需要提供一种净化空气的措施, 在人类过度利用环境资源的同时 通过采取有效的治理措施而提供改善的生存环境。 而利用众多高楼表 面让其湿^, 就可部分替代众多叶、 草的自净功能, 空中悬浮颗粒物 的尘降藉此实现。
悬浮颗粒物具有漂忽不定性, 水具吸附性, 利用二者的聚合性, 被水吸附的粉尘及溶解于水的有害物质随水流动并通过过滤被收集。 以此除尘, 需要创 ^聚合条件, 就是能像雨雪运动那样使尘物聚合并 下落。 提供相当大量的人造水流依附各楼表面, 提高水与运动浮尘的 相聚几率。 并立水流的运动出现越多, 相聚几率逾大, 对粉尘及有害 物质的吸附及溶解量越大, 净化空气的效果越好。
现今城市高楼林立, 已具备类似山区的地势条件。 若使高楼的表 面具有潮湿特性并结合绿地, 使城市中的高低处均有类似植被面的吸 附功能, 有可能将山区植被净化浮尘的功能移植于各楼表面。 那么城 市的空气净化仿生就可以起到吸附除尘的作用同时减少地面的灰尘扬 起, 即让城市具有类似于山区植被吸附随风飘移的颗粒物功能。
同样如果在各房间内提供大小不一的水流、 水帘或水幕, 则可以 减少由室内排放的悬浮颗粒物浓度, 使空气净化向良性循环的方向发 展。
因此, 需要一种为城市提供吸附悬浮颗粒物净化空气的有效方 法。
发明内容
高楼均为柱状体, 呈竖立存在状态。 让水由上自然向下流动或经 柱状表面流下, 流下的水再收集过滤返回楼顶。 如此环流不断, 柱状 体表面的含水湿性就有着保障。 空气中的悬浮颗粒物不断地被吸附并 流送至过滤处, 实现弱化空气污染的目的。
本发明减少空中悬浮颗粒物的方法, 就是利用水的吸附力、 流动 性来解决如何降低空中悬浮颗粒物的浓度问题。 釆用根据本发明的方 法, 可以改善室内外环境空气, 以有利于人的身心健康。
根据本发明的方法, 将一容器置于楼顶, 在容器底面侧边处设一 或多个出水口, 以便自漏。 室外容器可考虑有敞开形式, 以便收集雨 雪。 在出水口处连接一管道, 管中内置可产生虹吸作用的材质, 并于 管上设置多处分漏孔。 将管道固定于楼顶周边, 使漏出的水依附固体 面下流。 若非依固体面下落, 则漏出的水形成水帘的下落方式。 水附 着固体面向下流动, 则更有利于吸收风搅飘动的悬浮颗粒物, 达到净 化和湿润空气的目的。 最后在低处以一环绕楼体的水槽汇集所有流下 的漏水, 并将水过滤后通过循环装置置于顶处容器内。
根据本发明的方法, 将一容器置于室内高处, 在容器底面侧边处 设一或多个漏水孔, 以便自漏。 在漏水孔处连接一管道, 管中内置可 产生虹吸作用的材质, 并于管上设置多处分漏孔。 将管道布置于室内 高处, 使漏出的水依附固体面向下流动。 若非依固体面下落, 则漏出 的水形成水帘的下落方式。 水附着固体面向下流动, 则更有利于吸收 风搅飘动的悬浮颗粒物, 达到净化和湿润空气的目的。 最后在低处以 集水槽汇集所有流下的漏水, 并将水过滤后通过循环装置置于高处容 器内。
借助根据本发明的方法使人产生身临喷水池或瀑布边呼吸洁净空 气的清爽感觉。 根据本发明的方法有着维持湿化一定室内外表面的功 能。
根据本发明的空气净化的方法特别适合于炎热夏季的下雨前后的 气候条件和冬季室内干燥的空气条件。 在这两种条件下, 空气中的污 物对人的危害最大。 具体实施方式
首先为使楼表面有尽可能大的含水湿性面积, 就应有尽可能多的 水流下落流径, 如同密集水帘一样。 这要求高处应有尽可能多的出水 起点。 将导管环固于楼的顶端。 这里可借用农用滴灌管技术, 或其它 方式实现水尽可能多且微流省电的分水效果。 若采用管内填充化纤或 细沙或海绵条等持久且起虹吸作用的材质方式, 可比滴灌管技术更省 成本。 填充物起均勾各孔水压的作用, 易满足众多孔发生同漏功能。 为使楼顶水重力充分发挥, 环绕管应与水平面倾斜而非与水平面平 行。 每一漏水孔至墙面间应有固体材质相连, 如水泥、 封胶等不易脱 落材质。 保证漏水可沿该连接面过渡到墙面, 依墙而流下。 并且流至 底处的水通过一水槽回收汇流于一水箱内, 此集水槽也应倾斜水平面 固定, 其与墙面固贴侧应密封不漏水。 保证集水全部流入地面水箱内。 在集水箱内外设置滤水装置, 收集灰尘。 并设置压水泵, 将净水返回 楼顶再用。
用于漏水的管道可设置为多个管道, 以便有多股漏水并流。 用于 漏水的管道可形成为水槽水平安装, 以便使水以溢出形式运动下落而 漫成水幕。 漏水管道至集水槽间可培植花草以省人工浇灌, 并且汇集 流水的集水槽内可种植草木。
第一实施例
根据本发明的第一实施例, 提供一种在建筑物的外表面实现净化 空气的方法。 在楼顶表面设置底侧有一出水口的水箱, 该水箱还具备 收集雨雪的功能, 以便省水省电节约能源。 将一具有多处漏水功能的 管道接在出水口上, 并绕楼顶外墙面一周倾斜固定, 使漏水依墙流下。 在楼的底部, 例如地面, 环绕外墙一周倾斜布置一集水槽用于收集流 下的水, 该集水槽连接到有过滤功能的容器上用于过滤收集的水并将 水暂存以便循环使用。
第二实施例
该实施例与第一实施例基本相同, 其不同之处在于将底侧具有多 个出水口的容器置于楼顶。 将多个具有多处漏水功能的管分别接于多 个出水口上。 该多个漏水管绕楼顶外墙倾斜固定。
第三实施例
根据本发明的第三实施例, 提供一种在公共场所的大厅内净化空 气的方法。 在公共场所的大厅内, 在高处布置装水的容器, 连接布置 分漏管道, 并在低处布置集水槽。 使从分漏孔流出的水依墙或贴固体 面流下形成并流形式。 或使从分漏孔流出的水在空间面上形成水帘形 式。 滴下或流动含水面大小、 流径长短视具体条件定。 以此减弱灰尘 向室外输出的程度, 同时亦弱化室内的污染浓度。 可利用过滤循环装 置实现水的循环使用。
第四实施例
采用与第三实施例相同的方法, 在各种房间内的一定的墙和空间 面上实现动态的含水湿性。 以改善室内的空气质量, 使湿度增加、 悬 浮物的浓度降低。 同时亦减弱了对室外空间污染的输出程度。
所述三种实施例可组合使用, 可在一定程度上阻隔和抑制城市空 中悬浮颗粒物的来源。 并可减弱已在空中飘游的浮尘的浓度。 其中所 回收的物质是有价值的可再用物质。
