Description

气液固分离器、气液分离器及其电浆除硫脱硝设备
本申请要求申请日为2014年4月9日的中国专利申请CN201410140278.9的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明涉及工业废气净化领域，特别涉及一种气液固分离器、气液分离器及其电浆除硫脱硝设备。
背景技术
硫化物与氮氧化物的排放是造成大气污染及酸雨不断加剧的主要原因。据国家统计，燃煤电厂的二氧化硫排放量约占二氧化硫总排放量的50％。因此，对硫化物与氮氧化物排放的控制关系到节能减排目标的实现。
为了脱硫脱硝，工业上依然采用传统的湿法石灰石-石膏法烟气脱硫技术(CA-WFGD)和氨选择性催化还原法(NH3-SCR)，两种工艺联合使用可实现同时脱硫脱硝，但两个系统简单叠加造成工艺流程和系统复杂，占用面积大，投资和运行成本高，难以大规模推广应用。在湿法烟气脱硫脱硝的过程中，NOX中含有90％的以上难溶于水的NO，NO在室温(25℃)下的亨利常数仅为1.94×10-8mol/L·Pa，比SO2低三个数量级，仅通过调控pH和温度的方法难以显著提高NO在液相的溶解度，因此严重制约着脱硫脱硝的效率。
为了解决上述技术问题，申请公布号CN101940871A的中国专利公开了一种基于光化学高级氧化的同时脱硫脱硝系统，请结合图1予以理解，该脱硫脱硝系统1包括燃烧器11、静电除尘器12、换热器13、喷淋器14、雾化喷嘴15、紫外灯16、循环泵17、自添液塔18、分离塔19和烟囱110。(本申请要引用该文献的全文。)
使用时，通过自添液塔18的进气管111输入H2O2溶液，利用紫外灯16激发的紫外光激发分解H2O2，产生具有强氧化性的羟基自由基(OH-)，进而氧化脱除烟气中的NOX与SO2，反应产物为可资源化利用的硫酸与硝酸溶液，添加氨水后即可生成农业肥料。
为了保证辐射光功率，上述脱硫脱硝系统1需要设置多根紫外灯16，一方面会在喷淋器14内形成风阻，需要多个循环泵17抽送气体；另一方面存在光电转换效率和吸收效率低的问题，即电能转化成光能会有能量的损失，光能在穿透含有大量颗粒物的灰黑 烟气被H2O2吸收时，又存在光能衰减和吸收不完全的问题。经过光电转换损耗和吸收时的光能衰减，电能的实际利用率仍较低，并且难以提高。
此外，在热电厂燃煤过程中，采用不同种类和品质的煤炭(例如褐煤、烟煤或煤粉)以及不同的燃烧条件(是否过氧气燃烧和燃烧温度高低)会产生不同中心粒径的烟灰颗粒。
因此，对不同粒径烟灰颗粒的筛选也成为脱硫脱硝领域中面临的技术难题。经过对现有市场调查，发现市场销售的气液分离器不能够依据热电厂燃煤状况筛选不同中心粒径的烟灰颗粒。
发明内容

另外，该第一气固分离器4上设置有具有换热器的第一控温设备，该换热器为表面式换热器或直接接触式换热器，以便降低烟道废气的温度。

本实施例的电浆除硫脱硝设备的结构如下：
请结合图9予以理解，本实施例的电浆除硫脱硝设备包括一个供氨系统、如上所述的气液固分离器3、如上所述的第一气固分离器4、如上所述的气液分离器5以及如上所述的反应罐8，该电浆除硫脱硝设备还包括一个纳米电浆6、一个第一介质电浆7、一个 第二气固分离器9和一个烟囱90，该气液固分离器3、该第一气固分离器4、该气液分离器5，该纳米电浆6、该第一介质电浆7、该反应罐8、该第二气固分离器9和该烟囱90依次相互连通，该供氨系统与该反应罐8相互连通，以便向该反应罐8内通入氨气。图9仅示意性地给出了燃煤电厂锅炉2，实际上的锅炉2体积较为庞大。图10给出了第一气固分离器4与气液固分离器3和气液分离器5的管道连接结构。
请再次结合图9予以理解，具体上，该供氨系统包括一个氨气源10和第二介质电浆20，该氨气源10可以为氨气瓶或合成氨气的装置，该第二介质电浆20用于使得氨气分子吸附电荷，并且将吸附有电荷的氨气分子供应至该反应罐8内。
该纳米电浆6的两侧均设置有恒温控制系统并且形成夹持该纳米电浆6的结构，该第一介质电浆7的两侧均设置有恒温控制系统70并且形成夹持该第一介质电浆7的结构，夹层结构在庞大的电浆系统中的采用，使得升温速度加快并且控温更加精确，便于将反应温度维持在65℃至70℃范围内，提高了电离效率。
上述四个恒温控制系统结构相同，故仅以第二恒温控制系统60为例讲解，请结合图11予以理解，实际制作时，第二恒温控制系统60包括一个通风罩61、一个鼓风机62和一个温度控制箱63。
该通风罩61由一个转接管611、一个渐扩管612和一个矩形的转接头613组成，该转接头613均包括一个环形的通气隙，通气隙包括依次相互连通的一个上通气环道614、一个中通气环道615和一个下通气环道616，该通气隙用于循环加热气体。该下通气环道616的进气口、该鼓风机62、该温度控制箱63和该上通气环道614的排气口依次相互连通。
请结合图12予以理解，该温度控制箱63包括有一个具有保温层的外壳661，该外壳661内设置有一个电阻丝式加热器663，该保温层内设置有温度传感器662，该鼓风机62用于向该外壳661的内腔体抽送气体。
本实施例的气液固分离器和电浆除硫脱硝设备的工作原理如下：
请结合图9予以理解，使用时，锅炉废气依次流经该气液固分离器3、该第一气固分离器4、该气液分离器5，该纳米电浆6、该第一介质电浆7、该反应罐8、该第二气固分离器9和该烟囱90而排放至外界环境。
在该气液固分离器3内，对锅炉废气中的水分和烟灰颗粒进行初次过滤，表1给出了气液固分离器3对不同粒径颗粒的捕获效率。
表1、灰尘颗粒捕获效率

10.0 40.3

40.0 99.82
80.0 100
由上表1的数据可知：该气液固分离器3对粒径为10微米以上的灰尘颗粒静电除尘效果明显。
在该第一气固分离器4内，对锅炉废气中的水分和烟灰颗粒进行再次过滤，该第一气固分离器4(亦称为不锈钢网过滤器)采用2.5微米的不锈钢过滤网作为滤芯，取得了较高的分离效果，不锈钢网过滤器经设计可以每天反冲洗，不怕热，每半年保养一次，节能省电，彻底解决PM2.5不达标问题，表2给出了第一气固分离器4对不同粒径颗粒的捕获效率。
表2、灰尘颗粒捕获效率
粒径<um 分离效率％
2.5 57.75
4.0 97
6.0 99.19
10.0 100
23 100
30.0 100
40.0 100
80.0 100
由上表2的数据可知：该第一气固分离器4对粒径为2.5微米以上的灰尘颗粒静电除尘效果明显。
工业实施结果表明，依据该气液固分离器3和该第一气固分离器4对不同粒径灰尘 颗粒的处理优势，通过级联该气液固分离器3和该第一气固分离器4，粒径大于10um的颗粒分离率几乎达到100％，粒径大于2.5um的颗粒分离率达到80％以上，双重过滤处理方式能够将烟灰颗粒的含量控制在PM2.5的排放标准(低于0.075毫克/立方米)范围内。
因此，经过气液固分离器3和第一气固分离器4双重除尘处理后的废气体，在粉尘含量方面，完全能够满足苏州旺德科技有限公司生产的纳米电浆和第一介质电浆对相对湿度(RH)不能高于65％的要求，因此不会对电浆造成损坏。
另外，该第一气固分离器4中换热器还能够将锅炉废气(100℃至200℃)降温至45℃至80℃，以避免气体温度过高会对该纳米电浆6和该第一介质电浆7造成损伤，以及影响除硫脱硝的效率(除硫、脱硝热化学反应对温度要求严格)。
在该气液分离器5内，请同时结合图3予以理解，含有水汽的锅炉废气依次通过该进气口551、该旋流风道后、该内过滤桶52的腔体后，由该排气口552排出，由于该进气口551的轴线偏离该壳体55的轴心，因此锅炉废气会在该旋流风道内形成涡流，水汽凝结成水珠并在离心力的作用下甩向该壳体55的内壁面，在打开排水阀57后可以将积水放掉，干燥的锅炉废气透过该滤芯，并经该排气口552排出。
该挡流板531起到反射流体的作用，将从该进气口流入的气体阻挡向该引流板532，以便使得该引流板532引导该气体螺旋运动并撞向该滤芯的底部。虽然进气口551和排气口552均设置于该壳体55的上部，然而经过挡流板531和引流板532的协同作用后，锅炉废气能够在滤芯的轴向上得到均布，因此滤芯的过滤功能得以有效地使用。
使用引流板532螺旋导流的另一个好处是，气流不仅受到径向的离心力，而且还受到轴向的引导力，使得水汽快速凝结成水珠并斜向下均匀地甩向壳体55的内壁面，避免了仅仅甩向壳体55的内壁面的上部，而导致受冲击力不均的问题(噪音过大)。
依据热电厂燃煤状况的不同，可以相对地旋转该内过滤桶52和该外过滤桶53，以便改变过滤孔的有效面积，进而对不同中心粒径的液滴精细筛选。实验发现，在热电厂使用褐煤时，可以将滤孔的有效半径设置在10微米至15微米，在旋流速度大于25米/秒的条件下，可以去除废气中85％以上的水分。旋流速度的提升可以使用该内过滤桶内的旋流器，并且要确保该些旋流器的旋转方向与该引流板的引流方向相同。
请结合图6予以理解，碟形的集液过滤器上阵列的集液过滤孔能够汇集积液，并将烟灰颗粒收集于碟形腔体内，避免了直接将锅炉积液排放至外界环境引发水质污染，由排水阀57排放的达标的积水。
请结合图11予以理解，在该通风罩61内，混合气体通过转接管611甩向渐扩管612， 以便实现气体均布，该些通气隙用于循环加热气体，通过下通气环道616、中通气环道615和上通气环道614的依次加热，可以将混合气体的温度维持在65℃至70℃。该鼓风机62用于给加热气体提供循环动力，以便于维持加热气体的旋转。该电阻丝式加热器663用于电加热循环气体，以便将加热气体的温度维持在70℃。本实施例给出了电阻丝式加热器663，实际生产时，还可以采用气体换热器或水加热器。
请结合图9予以理解，在该纳米电浆6和该第一介质电浆7内，脱硫和脱硝过程的主要化学反应为：
H2O+e→H++OH-
O2+e→2O-
O2+O-→O3
O+H2O→OH-+OH-
H+O2→HO2 3-
经过纳米电浆6和第一介质电浆7的高压放电反应，产生大量的O-、O3、OH-、HO2 3-自由基。
SO2+O-→SO3
SO3+H2O→H2SO4
SO2+OH-→HSO3 -
HSO3 -+OH-→H2SO4
同理，还会产生硝酸，请结合图9予以理解，该氨气源10和该第二介质电浆20能够将吸附有电荷的氨气分子供应至该反应罐8内。该氨气源10的排气管道上设置有流量阀，能够调节氨气的注入流量接近化学反应的计量，在该反应罐8内发生以下化学反应：
H2SO4+2NH3→(NH4)2SO4
HNO3+NH3→NH4NO3
为了测试NOX的浓度、SO2的浓度、锅炉废气流量、电浆电压对NOX脱除率、SO2脱除率和能耗的影响，因此进行了除硫脱硝实验：
实验时控制锅炉废气流量为40L/H，改变纳米电浆6和第一介质电浆7的总功率(电压控制在36KV)，实验结果如图13所示，通过实验可知，NOX和SO2的脱除率和能耗并非为线性关系，在煤化工企业内，电功率控制在50W就可以去除90％以上的NOX和SO2，此时平均能耗仅为1.25W/L，另外还可以将电浆电压调高至100KV至150KV以便获得更好的脱硫脱硝效果。
本实施例的气液固分离器和电浆除硫脱硝设备具有以下技术效果：
第一、本发明的气液固分离器能够依据燃煤状况筛选不同中心粒径的烟灰颗粒，具体上，依据热电厂燃煤状况的不同，可以相对地旋转该内过滤桶34和该外过滤桶36，以便改变过滤孔的有效面积，进而对不同中心粒径的液滴精细筛选。
第二、旋流风道利用原有流体的动能，旋转离心水分，旋流风速可以通过第一压力表和第二压力表37测量，由于该进气口设置于该壳体的下部，该排气口设置于该壳体的上部，在旋流的过程中，水珠和烟道废气在该外过滤桶36的中部分离，水珠在重力和离心力的作用下斜向下甩向该壳体35的内壁面，并沿着该壳体35的内壁面汇聚到该壳体的底部，烟道废气旋流上升并且依次透过该外过滤桶36、该内过滤桶34和该烧结过滤器33，该外过滤桶36和该内过滤桶34形成的过滤孔，能够对液滴精细筛选，该烧结过滤器能够吸附烟道废气中的烟灰颗粒，实现对烟灰颗粒的粗过滤。
第三、能够正反轮换过滤烟灰颗粒，请结合图7予以理解，在第一时间，打开该第一进气管道410和该第一排气管道420上的阀门，关闭该第二进气管道430和该第二排气管道440上的阀门，使得烟道废气沿着第一方向吹向该过滤芯子41；在第二时间，关闭该第一进气管道410和该第一排气管道420上的阀门，打开该第二进气管道430和该第二排气管道440上的阀门，使得烟道废气沿着第二方向吹向该过滤芯子41。正反轮换过滤烟灰颗粒的优点在于，沿着第一方向吹向并且嵌入该过滤芯子41的折叠拐角处的烟灰颗粒，在第二方向的风力作用下，被吹出且重新过滤，经过正反方向交互轮回过滤，避免了烟灰颗粒嵌入折叠拐角形成结垢的问题。
第四、过滤效果优异且能够自动检测，请继续结合图7予以理解，鉴于该过滤芯子的相邻两个折叠层的夹角为5°至15°，烟道废气能够有效地吹向相邻两个折叠层之间的夹缝，并且具有垂直于折叠层的分力，便于烟灰颗粒的分离，过滤后的烟灰颗粒落入烟灰暂存腔45；由于烟灰暂存腔45分为两个并列的烟灰暂存区域，在正反轮换过滤烟灰颗粒的工况下，两个烟灰暂存区域的煤灰量基本保持相等，若存在煤灰量相差较大的情况，则可以判断煤灰过滤通道出现故障。
第五、混合均匀且合成反应充分，该些导流板能够阻挡流体和改变流向，使得流体均匀混合，另外还延长了气体路径，以便于合成反应充分进行，化肥颗粒合成后会沿着倾斜设置的导流板滚落并掉入该颗粒暂存腔88，在使用聚氨基甲酸酯涂层或聚四氟乙烯涂层后发现，化肥颗粒不会吸附或粘连于反应腔体和反应罐的内壁面。
第六、升温速度快且控温精确，该纳米电浆的两侧和该第一介质电浆的两侧均设置 有恒温控制系统，恒温控制系统设置于两侧，纳米电浆和第一介质电浆夹设于中间，形成夹层结构，升温速度快且控温精确，便于将反应温度维持在65℃至70℃的范围。
第七、该电浆除硫脱硝设备不仅能源利用效率高而且除硫脱硝效率强。鉴于该纳米电浆电压和该第一介质电浆能够产生10KV-200KV的高压电，电浆内部的高压电极能够瞬间将油烟废气中的分子电离成游离状态的离子，因而能源利用效率高而且除硫脱硝效率强，电浆内部的触媒涂层能够引导该些游离状态的离子发生化学反应，因此没有臭氧产生，另外，能耗仅为其它除硫脱硝设备的几十分之一至百分之一。
第八、该电浆除硫脱硝设备采用模块化堆叠设计，具有体积较小、结构紧凑和扩展能力强的优点，例如，多个第一介质电浆能够横向堆叠成第一介质电浆单元，多个第一介质电浆单元横向堆叠成第一介质电浆模组，多个第一介质电浆模组纵向堆叠成电浆除硫脱硝设备，因此具有体积较小、结构紧凑和扩展能力强的优点。
第九、多层绝缘且防止漏电，每一第一介质电浆的外表面采用聚氯乙烯材料进行绝缘，在第一介质电浆横向堆叠成第一介质电浆单元后，每一第一介质电浆单元的外表面采用聚氯乙烯材料进行绝缘，在第一介质电浆单元横向堆叠成第一介质电浆模组后，每一第一介质电浆模组的外表面采用聚氯乙烯材料进行绝缘，因此多层绝缘，能够防止电浆外漏，达到省电和安全的目的。
虽然以上描述了本发明的具体实施方式，但是本领域的技术人员应当理解，这些仅是举例说明，在不背离本发明的原理和实质的前提下，可以对这些实施方式做出多种变更或修改。因此，本发明的保护范围由所附权利要求书限定。
