Description
—种絮凝装置
技术领域
[0001 ] 本实用新型涉及一种絮凝装置。
背景技术
[0002]目前，轴流式机械搅拌在絮凝搅拌中得到广泛的应用，该搅拌方式主要通过叶轮旋转把动量传给周围的液体，使液流在全池内实现上下流的循环流动，这种全池内上下流循环流动通常被称为主体对流扩散，在通常情况下，该搅拌方式要求叶轮能以较低的能耗提供高的轴向循环流量，但在现有轴流式絮凝搅拌技术中，由于搅拌叶轮的旋转作用，往往在产生轴流的同时形成大量的湍流和涡流，导致搅拌器在运转时叶片产生失速，输入液体的能量消耗在湍流和涡流区域，降低搅拌机搅拌效率，影响絮凝效果。
[0003] 实用新型目的·
[0004] 本实用新型的目的在于提供一种混合均匀的絮凝装置。
[0005] 为了实现上述目的，采用以下技术方案：一种絮凝装置，包括具有进水管和出水管的筒体，其特征在于：所述筒体内设置有上下开口的中心导流筒，搅拌器的带有叶片的旋转轴伸入中心导流筒内，进水管出水口位于中心导流筒底部，加药管的出口位于中心导流筒内叶片下方、进水管出口的上方。
[0006] 作为进一步的优化，为了进一步的稳流，所述中心导流筒内部设有中心稳流板，夕卜部设有与絮凝装置的外部筒体固定衔接的翼板。
[0007] 本实用新型采用中心导流筒，轴流式主流扩撒比例高，涡流扩散比例小，液流对搅拌器的逆向剪切力小，搅拌效率高，絮凝效果好，矾花不易破碎，能节约20°/「30%的搅拌功率。
附图说明
[0008] 图I是本实用新型的结构示意图；
[0009] 图2是图I的A-A剖面图
[0010] 图I中，件I为进水管，件2为中心导流筒，件3为中心稳流板，件4为十字翼板，件5为轴流式搅拌器，件6为加药管，件7为出水管。
具体实施方式
[0011] 如图I和图2所示，液流经进水管I进入絮凝装置中，计量的絮凝剂通过加药管6投加至进水管上部，絮凝剂在轴流式搅拌器5作用下与液流快速均匀混合，同时，轴流式搅拌器产生的提升力将水由下向上提升，液流在中心稳流板3的作用下自下而上轴流通过中心导流筒，到达顶部后流向导流筒外部十字翼板区。在该反应区中水流在十字翼板4的作用下轴流自上而下到达池底，部分水流再在搅拌器的提升作用下进入导流筒，形成良好的上下流循环流态。
[0012] 本实用新型具有液流混合均匀、传质速率快、转化速率高、能耗低、矾花不易破碎等优点。
