Description

一种铁碳微电解反应器 技术领域
本申请涉及废水处理设备的技术领域，特别涉及一种铁碳微电解反应器。
背景技术
随着化工工程的快速发展，社会上产生大量难降解的废水，采用传统的污水处理工艺或者设备，难以处理达标。针对难降解的化工废水，常规采用较多的处理单元有芬顿、铁碳微电解等方法。其中，铁碳微电解法，又称内电解法，是处理高浓度有机废水的一种理想方法，其主要针对有机物浓度大、高毒性、高色度、难生化的废水处理，可大幅度地降低废水的色度和COD，提高B/C比值即提高废水的可生化性，可广泛应用于印染、化工、电镀、制浆造纸、制药、洗毛、农药、酒精等各类工业废水的处理及处理水回用工程。
铁碳微电解是一种电化学方法，通常以零价铁和活性炭分别作为阳极和阴极。在水中，当它们相互接触，阳极释放电子，阴极接受并转移电子，微观上可形成无数的微型原电池，微电解反应也加速了铁电极释放电子。零价铁作为阳极，失去两个电子形成Fe2+(即Fe-2e→Fe2+)，活性炭作为阴极，接受电子并在有氧条件下形成[H]及O〃(即O2++4H++4e→2O〃+4[H])，并表现出较强的氧化还原活性。此外，还原铁粉失去电子与氧形成(如Fe(OH)2+、Fe(OH)2 +等)后并进一步氧化形成良好的氢氧化亚铁(Fe(OH)2)和氢氧化铁(Fe(OH)3)絮凝体，与污染物之间通过共沉淀、吸附和粒子间架桥的组合进行转化去除。
因此，铁碳微电解的电极反应产生强还原性的自由氢基[H]，同时也会产生副产物Fe2+和Fe3+。工业废水含有大量的有机物，主要由C、N、P、S等元素组成，铁碳微电解反应器长期运行后会形成铁的磷氧化物，如Fe3(PO4)2〃8H2O和FePO4〃8H2O，或和S生成FeS，且水中溶有氧气，还会与铁生成Fe2O3和Fe3O4。这些化合物覆盖了填料的表面及部分孔洞，不及时冲刷，形成了钝化膜，阻碍铁碳之间有效的接触面积，影响铁碳之间原电池的作用，使铁碳间的原电池作用减弱，降低铁碳微电解反应对废水的处理效率。随着运行时间的延长，铁碳填料钝化膜越来越致密，板结越来越严重，抑制了[H]的生成，直至电解完全不能进行。由于铁屑的活性太强，如果不能把铁屑隔开就会相互粘接在一起，铁的化合物也会与铁屑连接起来形成块状，从而导致板结和沟流。
由于传统的铁碳微电解反应器，如专利CN212770010U，只是底部曝气且水体流向紊乱不均匀存在死区，填料依然存在容易形成钝化及板结的情形，使微电解原电池作用减弱，极大地影响废水处理效果。长期运行后填料板结严重，沉积在设备底部，还会导致运行中堵塞设备。
发明内容
基于此，有必要提供一种更好地避免填料存在钝化及板结的铁碳微电解反应器。
一种铁碳微电解反应器，包括：
外罐，形成有相连通的收容腔及第一安装孔；
内罐，位于所述收容腔内并与所述外罐连接，所述内罐的外壁与所述外罐的内壁之间形成有环流间隙，所述内罐的两端分别设有第一环流介入面及第二环流介入面，所述内罐形成有避位贯孔，所述避位贯孔至少贯穿于所述第一环流介入面设置；
曝气装置，穿设于所述第一安装孔内并与所述外罐连接，所述曝气装置包括第一曝气机构及第二曝气机构，所述第一曝气机构的曝气侧朝向所述第一环流介入面设置，所述第二曝气机构穿设于所述避位贯孔，且所述第二曝气机构的曝气侧位于所述内罐的内部，所述第一曝气机构的曝气方向与所述第二曝气机构的曝气方向存在预设夹角，以形成有依次循环通过所述第一环流介入面、所述内罐的内腔、所述第二环流介入面及所述环流间隙的曝气环流。

如图1及图3所示，在其中一个实施例中，铁碳微电解反应器10还包括平台护栏1200及护笼1300，平台护栏环绕设置于外罐100的外周壁，平台护栏邻近外罐100的顶部设置，以便使用者观察外罐100内部的反应情况。平台护栏1200形成有安装口802，护笼沿外罐100的外周壁设置，且护笼穿设于安装口，护笼1300内设有爬梯1310，以便使用者通过爬梯进入平台护栏的位置。

如图1所示，在其中一个实施例中，铁碳微电解反应器10还包括PH控制装置1100，PH控制装置1100包括加酸供应机构1110及在线PH计1120，加酸供应机构1110与收容腔102连通，在线PH计1120设于收容腔102内，在线PH计1120用于检测收容腔102内的曝气环流的PH值，加酸供应机构1110用于根据PH值控制加酸量，使反应器内水体稳定控制在一定的PH范围。在本实施例中，加酸供应机构1110包括加酸管1112及加酸泵1114，加酸泵设于加酸管上，加酸泵的控制端及在线PH计的控制端均与控制器电连接，以实现PH值自动调节。当在线PH计测量的PH值高于预设值时，控制器控制加酸泵工作，以对反应器内的PH值进行调节。在线PH计与加酸泵联动，将反应器内水体稳定控制在一定的PH范围。进一步地，加酸供应机构1110还包括设于加酸管上的加药阀1116，加药阀用于控制调节通过加酸管的流量。
与现有技术相比，本申请包括但不仅限于以下优点：
1、本申请的铁碳微电解反应器10，第一曝气机构310的曝气侧朝向第一环流介入面201设置，第二曝气机构320穿设于避位贯孔204，且第二曝气机构320的曝气侧位于内罐200的内部，第一曝气机构310的曝气方向与第二曝气机构320的曝气方向存在预设夹角，以形成有依次循环通过第一环流介入面201、内罐200的内腔、第二环流介入面203及环流间隙202的曝气环流，使反应器内部水体形成较好的环流，进而使废水与填料接触更加充分，可促进反应的进行；
2、上述的铁碳微电解反应器10，控制水体力学，即巧妙控制第一曝气机构310及第二曝气机构320的动作，形成“纵向曝气”、“横向曝气”、“纵、横向曝气”三种模式，如此形成向上水流的作用下，解决了填料钝化及板结问题，如此减少了填料更换难度，提高了铁碳填料的利用率；
3、反应器内部水体形成较好的环流，水体流动混合的速度较快，通过在线PH计与加酸供应机构联动控制，可实现反应器内整体水体PH值能稳定在较为精确的范围内，从而促使反应更好的进行；
4、由于翼环件206环绕于第一环流介入面201设置，避免了曝气头在曝气过程中对内罐外侧的水体造成扰动，从而整 体形成内罐内侧水流向上、内罐外侧水流向下的环流，使翼环件206起到引导曝气环流往第一环流介入面201方向流动的作用，进而使曝气环流更好地作用于第一环流介入面201；
5、泥斗700位于外罐100的内底壁并与外罐100连接，使外罐100的底部更好地聚集淤泥，使淤泥更好地通过排泥过孔组612排出，同时方便引导曝气环流向上流动；
6、出水挡板520位于收容腔102内并与外罐100连接，且出水管510与收容腔102连通的端部朝向出水挡板520设置，出水挡板520与收容腔102的内壁之间围成有缓流道522，缓流道522与出水管510连通，使出水挡板520起到阻挡浮渣的作用，即阻挡了漂浮的杂质进入出水管510，从而堵塞出水管510；同时也阻挡了内罐200顶部的水流直接出水，造成局部短流的现象；
7、曝气立管326位于内罐200之外的部位连接于旋转手柄329，以便通过旋转手柄329带动曝气立管326相对于第二曝气主管322旋转，以便调节第二曝气主管322的曝气方向，操作人员在外罐的外侧即可进行操作，无需人工进入外罐内，操作更加安全，方便简单。
