Description

一种涡旋固液分离器 一种涡旋固液分离器
技术领域
本发明涉及液体或气体的净化处理领域，特别涉及一种涡旋固液分离器。
背景技术
目前固液分离中，多采取阻隔式装置（比如：砂层，滤芯，膜…）等，此类分离装置存在占地多、使用材料多、成本高及能耗高等缺陷。且目前固液分离设备的过滤原理均是截留，其中，截留材料的使用和流体的推动力本身是一对矛盾，因而无法克服上述弊端。
发明内容
本发明为了解决目前固液分离器结构复杂、体积大且成本高等问题，提出了一种 利用流体本身的推动力，在不使用任何滤材的情况下可实现高效过滤的涡旋固液分离器。
本发明技术方案是这样实现的：
一种涡旋固液分离器，包括进水管道； 所述进水管道底部设置有固定叶轮； 所述进水管道下方设置有 漩涡扩散器，所述涡旋扩散器内设置有连通所述进水管道的喇叭状涡流通道；所述喇叭状涡流通道下方 连通有 沉降分离筒体；所述沉降分离筒体的中央位置设置有澄清液出口管，所述澄清液出口管的进口端伸入至所述喇叭状涡流通道的底部，且在所述澄清液出口管的进口端的外部设置有杂质止回板； 所述澄清液出口管的出口端伸出所述沉降分离筒体；所述沉降分离筒体侧壁的底部设置有杂质出口。
进一步，所述固定叶轮具有多个叶片，所述相邻的两个叶片之间的间隙大于杂质的体积，以便杂质可以穿过叶轮并被离心甩出。
进一步，所述叶片相对水平线的倾斜角度优选为 25~35 度，以便增大涡流内杂质的离心速度，使得杂质被有效甩向水流外层。
进一步，喇叭状涡流通道的顶口与底口的直径比例为 1 ： 3~1 ： 5 ，从而有效提高澄清液的纯度。
进一步，所述喇叭状涡流通道的高度与其底口直径的长度比例为 8 ： 1 。
更进一步，还包括控制进水管道内水流速度的流速调节器，所述流速调节器所调节的水流流速与水中杂质的浓度呈正比 ，由此在杂质浓度大的时候，水流速度相应增大可以使得涡旋中的杂质离心速度大，被过滤掉的效率更高。
使用本发明技术方案，将现有固液分离中截留防水改为疏导，通过流体本身的推动力，在不使用任何滤材的情况下，实现高效过滤，从而大大节省成本和能源。
附图说明
图 1 为本发明具体实施例中分离器的外部结构示意图；
图 2 为图 1 中分离器 A-A 截面的剖面结构示意图；
图 3 为本发明具体实施例中分离器的液体流向原理图。
具体实施方式
见图 1 、图 2 及图 3 所示，本发明具体实施例中，一种涡旋固液分离器，包括进水管道 1 ，在进水管道 1 的下方设置有漩涡扩散器 2 ，漩涡扩散器 2 内部具有 喇叭状涡流通道 21 ， 喇叭状涡流通道 21 连通进水管道 1 。在 喇叭状涡流通道 21 的下方 连通有 沉降分离筒体 3 ；其中，在进水管道 1 的底部设置有固定叶轮 11 ；在沉降分离筒体 3 的中央位置设置有澄清液出口管 4 。其中，澄清液出口管 4 的进口端 41 伸入至 喇叭状涡流通道 21 的底部，且在澄清液出口管 4 的进口端 41 的外部设置有杂质止回板 42 ；澄清液出口管 4 的出口端 43 伸出沉降分离筒体 3 ；在沉降分离筒体 3 的侧壁的底部设置有杂质出口 31 。
本发明具体实施例中，固定叶轮 11 优选具有多个叶片 111 ，其中，相邻叶片 111 之间的间隙大于杂质的体积，使得液体中的杂质可以穿过叶片 111 之间的间隙并被离心甩出。其中，叶片 111 相对水平线的倾斜角度优选为 25~35 度，由此增大 涡流产生的效率以及 涡流内杂质 5 的离心速度，使得杂质 5 被有效甩向水流外层。
本发明具体实施例中，喇叭状涡流通道的顶口与底口的直径比例优选为 1 ： 3~1 ： 5 ，并且喇叭状涡流通道 21 的高度与其底口直径的长度比例优选为 8 ： 1 ，以有效提高澄清液的纯度。
本发明具体实施例中，涡旋固液分离器还包括控制进水管道水流速度的流速调节器（附图中未标记），流速调节器所调节的水流流速与液体中杂质的浓度呈正比 。当杂质浓度大的时候，水流速度相应增大，可以增强涡旋中的杂质离心的速度，杂质被过滤掉的效率更高。
见图 3 本发明 液体流向原理图，本发明技术方案的 固液分离器的工作方式为： 含杂质 5 的流体 6 以一定的速度流入进水管 1 并穿过固定叶轮 11 ，固定叶轮 11 使得流体产生漩涡，漩涡夹带固体杂质 5 在喇叭状涡流通道 21 内做离心运动，并使得杂质 5 聚集到水流的外层，当杂质 5 旋转到杂质止回板 42 处时，杂质 5 被杂质止回板 42 挡回并进入 沉降分离筒体 3 内，通过沉降分离筒体 3 侧壁的杂质出口 31 排出 ，而喇叭状涡流通道 21 的水流中央澄清的液体将直接流入澄清液出口管 4 的 进口端 41 ，并最终通过出口端 43 流出。
使用本发明技术方案，通过将现有固液分离中截留防水改为疏导，通过流体本身的推动力，在不使用任何滤材的情况下，实现高效过滤并降低了制造成本。
以上仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内 。
