Description

一种高负荷厌氧系统内高效撬装式三相分离器 技术领域
本发明涉及厌氧装备领域，特别是涉及一种高负荷厌氧系统内高效撬装式三相分离器系统。
背景技术
三相分离器用于高浓度的污水处理UASB或IC等厌氧反应器中。在处理各种有机废水时，反应器内一般情况下均能形成厌氧颗粒污泥，而厌氧颗粒污泥不仅具有良好的沉降性能，而且有较高的产甲烷活性。由于厌氧反应器设有三相分离器，使得反应器内的污泥不易流失，所以反应器内能维持很高的生物量，平均浓度能达到80g/L左右；同时沼气聚集于三相分离器顶部，通过气管排出。正是由于三相分离器的存在，才能保障高浓度有机废水经过厌氧反应器预处理后，有机物得到大量去除，COD大幅度下降
三相分离器同时具有两个功能：收集反应室产生的沼气和使分离器内的悬浮物有效沉降。传统三相分离器其工作原理是：反应器内含有大量的气泡的三相混合流上升至分离器底部，碰到反射板，气体折流而上，与固液相分离集中到气室排放。固液混合液进入分离器，在沉淀区分离，澄清液通过溢流堰排出。失去气泡搅动作用的污泥发生絮凝、沉降和浓缩，然后沿斜壁下滑，通过污泥回流口返回反应区。由于沉淀区内液体无气泡，污泥回流口以上的混合液比重大于反应器内液体比重，使浓缩后的污泥能够返回反应区，由此实现固液气的三相分离。
三相分离器要实现良好的分离效果，应该满足以下条件：
①、水和污泥的混合物进入沉淀区之前，气泡必须分离；
②、污泥在沉淀器中的停留时间要短，避免在沉淀区中产气；
③、沉淀区内表面负荷采用较小值，使污泥有效沉降；
综上所述，现有的三相分离器普遍存在停留时间短与低表面负荷的矛盾，两者难以兼顾，最终造成三相分离器泥水分离不清，出水悬浮物浓度高，难以达到设计要求，且对后续生化处理过程存在干扰。
为克服传统三相分离器的不足，借鉴内置式沉淀池和侧向流斜板沉淀池的特点，在传统三相分离器的沉淀区域引入倒V型斜板，大幅度减小三相分离器的体积，提高厌氧反应区的占比和厌氧污泥的充满度，从而提高厌氧池的容积利用率，提高厌氧负荷，减 小反应池的容积。
同时由于三相分离器结构复杂，现场施工难度高，容易造成安装质量低，因此提出撬装式倒V型三相分离器，通过三相分离器的撬装化简化现场安装工序，缩短施工周期，提高安装质量。

矩形框架与第一框架21固定连接，矩形框架中的支撑柱均沿竖直设置，相临的支撑柱上对称的开设有凹槽，用于将第一倒V型板251的两个连接板卡接在凹槽中。且支撑柱上的凹槽为多个，且于支撑多层第一倒V型板251。第一倒V型板251的层间距离为50～100mm。
矩形框架中设置多根支撑柱，用于支撑多行第一倒V型板251，每行第一倒V型板251均沿泥水混合液流动方向设置。每行第一倒V型板251的间距形成斜板间污泥沉淀通道，斜板间污泥沉淀通道宽度为20-50mm。
每两个倒V型板支架252之间为一列第一倒V型板251，倒V型沉淀区25平行设置有多个倒V型板支架252和多列第一倒V型板251，在第二倒V型板13上，每个倒V型板支架252下方对应位置，均设置有沼气排放口14。防止沼气在在第一倒V型板251下方聚集。
所以，通过设置多个倒V型板支架252、倒V型板支架252中设置多个支撑柱、以及支撑柱上设置多个凹槽，每两个相对设置的凹槽中放置一个第一倒V型板251，则形成多列多行多层的第一倒V型板251结构。
与出水配水区26相临的倒V型板支架252为末端倒V型板支架，所述末端倒V型板支架的支撑柱的宽度大于其它倒V型板支架252的支撑板的宽度。以便在出水配水区26产生较急的水流。
安装过程中本发明的三相分离器与水平面成1°倾角，以便于沉淀区进行排气。
