Description

发动机尾气处理系统和方法 技术领域
本发明属于环保领域，涉及一种发动机尾气处理系统和方法。
背景技术
现有技术中，通常通过柴油颗粒物过滤器(DPF)来进行颗粒物过滤。其中，DPF以燃烧方式工作，即利用积碳在多孔结构中充分堵塞后升温达到燃点后通过自然或者助燃的方式燃烧。具体地，DPF的工作原理如下：带有颗粒物的进气进入DPF的蜂窝状载体，颗粒物在蜂窝装载体中被拦截，当进气流出DPF时大部分的颗粒物已经被过滤掉。DPF的载体材料主要为堇青石、碳化硅、钛酸铝等，具体可根据实际情况进行选择使用。然而，上述方式存储以下缺陷：
(1)当DPF捕集到一定程度的颗粒物后就需要再生，否则发动机排气背压上升，工作状态恶化，严重影响性能及油耗，更有甚者为堵死DPF导致发动机无法工作。因此，DPF需要定期维护和添加催化剂。即使有定期维护，颗粒物的积聚限制了排气流，因此增加了背压，这会影响发动机性能和燃油消耗。
(2)DPF的除尘效果不稳定，无法满足发动机进气处理的最新过滤要求。
静电除尘是一种气体除尘方法，通常在冶金、化学等工业领域中用以净化气体或回收有用尘粒。现有技术中，由于占用空间较大、系统结构复杂、除尘效果差等问题，无法基于静电除尘对发动机进气颗粒物进行处理。
发动机对环境的污染主要来自发动机的排气产物即发动机尾气，目前对于柴油机尾气净化，常规的技术路线是采用氧化催化剂DOC除去碳氢化合物THC和CO，同时把低价态NO氧化成高价态的NO 2；在DOC之后采用柴油机微粒捕集器DPF对颗粒物PM进行过滤；在柴油机微粒捕集器DPF之后喷射尿素，尿素在排气中分解成氨气NH 3，NH 3在其后的选择性催化剂SCR上和NO 2发生选择性催化还原反应，生成氮气N 2和水。在最后在氨气氧化催化剂ASC上将过量的NH 3氧化成N 2和水，现有技术对发动机尾气的净化需添加大量尿素，且净化效果一般。
发明内容
鉴于以上所述现有技术的缺点，本发明的目的在于提供一种发动机排放处理系统和方法，用于解决现有技术除尘系统需要定期维护以及效果不稳定和需添加大量尿素处理尾气且净化 尾气效果一般中至少一个问题。同时，本发明通过研究发现了现有电离除尘技术中存在的新问题，并通过一系列技术手段来解决，例如，当尾气温度或发动机温度低于一定温度时，发动机尾气中可能含有液体水，本发明在尾气电场装置前安装除水装置，脱除尾气中的液体水，提高电离除尘效果；在高温条件下，通过控制尾气电场装置阳极的集尘面积与阴极的放电面积比、阴极/阳极的长度、极间距以及设置辅助电场等，有效减少电场耦合，并使得尾气电场装置在高温冲击下仍具有高效率的集尘能力。因此，本发明适合在苛刻条件下作业，并保证除尘效率，故从商业角度出发，本发明完全可适用于发动机。
本发明提供一种发动机排放处理系统，包括尾气除尘系统、尾气臭氧净化系统中的至少一个。所述尾气除尘系统包括尾气除尘系统入口、尾气除尘系统出口、尾气电场装置。所述尾气臭氧净化系统包括反应场，用于将臭氧流股与尾气流股混合反应。该发动机排放处理系统能有效地处理发动机排放，使得发动机的排放更加清洁。

具体实施方式
以下由特定的具体实施例说明本发明的实施方式，熟悉此技术的人士可由本说明书所揭露的内容轻易地了解本发明的其他优点及功效。
须知，本说明书所附图式所绘示的结构、比例、大小等，均仅用以配合说明书所揭示的内容，以供熟悉此技术的人士了解与阅读，并非用以限定本发明可实施的限定条件，故不具技术上的实质意义，任何结构的修饰、比例关系的改变或大小的调整，在不影响本发明所能产生的功效及所能达成的目的下，均应仍落在本发明所揭示的技术内容得能涵盖的范围内。同时，本说明书中所引用的如“上”、“下”、“左”、“右”、“中间”及“一”等的用语，亦仅为便于 叙述的明了，而非用以限定本发明可实施的范围，其相对关系的改变或调整，在无实质变更技术内容下，当亦视为本发明可实施的范畴。
根据本发明的一个方面，发动机尾气处理系统，包括尾气除尘系统和尾气臭氧净化系统。
于本发明一实施例中发动机尾气处理系统包括尾气除尘系统。尾气除尘系统与发动机的出口相连通。发动机排放的尾气将流经尾气除尘系统。
于本发明一实施例中，所述尾气除尘系统还包括除水装置，用于在尾气电场装置入口之前去除液体水。
于本发明一实施例中，当尾气温度或发动机温度低于一定温度时，发动机尾气中可能含有液体水，所述除水装置脱除尾气中的液体水。
于本发明一实施例中，所述一定温度在90℃以上、100℃以下。
于本发明一实施例中，所述一定温度在80℃以上、90℃以下。
于本发明一实施例中，所述一定温度为80℃以下。
于本发明一实施例中，所述除水装置为电凝装置。
本领域技术人员没有认识到如下技术问题：在尾气或发动机温度低时，尾气中会有液体水，吸附在尾气除尘电场阴极和尾气除尘电场阳极上，造成尾气电离除尘电场放电不均匀、打火，而本申请的发明人发现此问题，并提出尾气除尘系统设置除水装置，用于在尾气电场装置入口之前去除液体水，液体水具有导电性，会缩短电离距离，导致尾气电离除尘电场放电不均匀，易导致电极击穿。所述除水装置在发动机冷启动时，在尾气进入尾气电场装置入口之前脱除尾气中的水珠即液体水，从而减少尾气中的水珠即液体水，减少尾气电离除尘电场放电不均匀及尾气除尘电场阴极和尾气除尘电场阳极击穿，从而提高电离除尘效率，取得预料不到的技术效果。所述除水装置没有特别的限制，现有技术中能实现去除尾气中的液体水都适用本发明。
于本发明一实施例中，所述尾气除尘系统还包括补氧装置，用于在尾气电离除尘电场之前添加包括氧气的气体，比如空气。

于本发明一实施例中，至少根据尾气颗粒含量决定补氧量。
本领域技术人员没有认识到如下技术问题：在某些情况下，尾气会没有足够的氧气产生足够的氧离子，造成除尘效果不好，即，本领域技术人员没有认识到发动机尾气中的氧气可能不足以支持有效电离，而本申请的发明人发现此问题，并提出本发明尾气除尘系统：包括补氧 装置，可以通过单纯增氧、通入外界空气、通入压缩空气和/或通入臭氧的方式添加氧气，提高进入尾气电离除尘电场尾气含氧量，从而当尾气流经尾气除尘电场阴极和尾气除尘电场阳极之间的尾气电离除尘电场时，增加电离的氧气，使得尾气中更多的粉尘荷电，进而在尾气除尘电场阳极的作用下将更多的荷电的粉尘收集起来，使得尾气电场装置的除尘效率更高，有利于尾气电离除尘电场收集尾气颗粒物，取得预料不到的技术效果，同时还取得新的技术效果：能起到降温的作用，增加电力系统效率，而且，补氧也会提高尾气电离除尘电场臭氧含量，有利于提高尾气电离除尘电场对尾气中有机物进行净化、自洁、脱硝等处理的效率。尾气均风

在工作时，在带污染物的气体进入尾气除尘电场阳极和尾气除尘电场阴极形成的尾气电离除尘电场之前，且带污染物的气体通过尾气前置电极时，尾气前置电极使气体中的污染物带电。当带污染物的气体进入尾气电离除尘电场时，尾气除尘电场阳极给带电的污染物施加吸引力，使污染物向尾气除尘电场阳极移动，直至污染物附着在尾气除尘电场阳极上。

于本发明一实施例中尾气电场装置包括尾气流道，尾气前置电极位于尾气流道中。于本 发明一实施例中尾气前置电极的截面面积与尾气流道的截面面积比为99％～10％、或90～10％、或80～20％、或70～30％、或60～40％、或50％。尾气前置电极的截面面积是指尾气前置电极沿截面上实体部分的面积之和。于本发明一实施例中尾气前置电极带负电势。
于本发明一实施例中当尾气通过尾气电场装置入口流入尾气流道中，尾气中导电性较强的金属粉尘、雾滴、或气溶胶等污染物在与尾气前置电极相接触时，或与尾气前置电极的距离达到一定范围时会直接带负电，随后，全部污染物随气流进入尾气电离除尘电场，尾气除尘电场阳极给已带负电的金属粉尘、雾滴、或气溶胶等施加吸引力，使已带负电的污染物向尾气除尘电场阳极移动，直至该部分污染物附着在尾气除尘电场阳极上，实现将该部分污染物收集起来，同时，尾气除尘电场阳极与尾气除尘电场阴极之间形成的尾气电离除尘电场通过电离气体中的氧获得氧离子，且带负电荷的氧离子在与普通粉尘结合后，使普通粉尘带负电荷，尾气除尘电场阳极给该部分带负电荷的粉尘等污染物施加吸引力，使粉尘等污染物向尾气除尘电场阳极移动，直至该部分污染物附着在尾气除尘电场阳极上，实现将该部分普通粉尘等污染物也收集起来，从而将尾气中导电性较强和导电性较弱的污染物均收集起来，并使得尾气除尘电场阳极能收集尾气中污染物的种类更广泛，且收集能力更强，收集效率更高。
于本发明一实施例中尾气电场装置入口与发动机的出口相连通。
于本发明一实施例中尾气电场装置可包括尾气除尘电场阴极和尾气除尘电场阳极，尾气除尘电场阴极与尾气除尘电场阳极之间形成电离除尘电场。尾气进入电离除尘电场，尾气中的氧离子将被电离，并形成大量带有电荷的氧离子，氧离子与尾气中粉尘等颗粒物结合，使得颗粒物荷电，尾气除尘电场阳极给带负电荷的颗粒物施加吸附力，使得颗粒物被吸附在尾气除尘电场阳极上，以清除掉尾气中的颗粒物。

于本发明一实施例中尾气除尘电场阴极包括若干阴极棒。于本发明一实施例中阴极棒的直径不大于3mm。于本发明一实施例中阴极棒使用容易放电的金属棒或合金棒。阴极棒的形状可以为针状、多角状、毛刺状、螺纹杆状或柱状等。阴极棒的形状可以根据尾气除尘电场 阳极的形状进行调整，例如，若尾气除尘电场阳极的积尘面是平面，则阴极棒的截面需要设计成圆形；若尾气除尘电场阳极的积尘面是圆弧面，则阴极棒需要设计成多面形。
于本发明一实施例中尾气除尘电场阴极穿设于尾气除尘电场阳极内。
于本发明一实施例中尾气除尘电场阳极包括一个或多个并行设置的中空阳极管。当中空阳极管有多个时，全部中空阳极管构成蜂窝状的尾气除尘电场阳极。于本发明一实施例中中空阳极管的截面可呈圆形或多边形。若中空阳极管的截面呈圆形，尾气除尘电场阳极和尾气除尘电场阴极之间能形成均匀电场，中空阳极管的内壁不容易积尘。若中空阳极管的截面为三边形时，中空阳极管的内壁上可以形成3个积尘面，3个远角容尘角，此种结构的中空阳极管的容尘率最高。若中空阳极管的截面为四边形，可以获得4个积尘面，4个容尘角，但拼组结构不稳定。若中空阳极管的截面为六边形，可以形成6个积尘面，6个容尘角，积尘面和容尘率达到平衡。若中空阳极管的截面呈更多边形时，可以获得更多的积尘边，但损失容尘率。于本发明一实施例中中空阳极管的管内切圆直径取值范围为5mm-400mm。
于本发明一实施例中尾气除尘电场阴极安装在阴极支撑板上，阴极支撑板与尾气除尘电场阳极通过尾气绝缘机构相连接。于本发明一实施例中尾气除尘电场阳极包括第三阳极部和第四阳极部，即所述第三阳极部靠近尾气电场装置入口，第四阳极部靠近尾气电场装置出口。阴极支撑板和尾气绝缘机构在第三阳极部和第四阳极部之间，即尾气绝缘机构安装在电离电场中间、或尾气除尘电场阴极中间，可以对尾气除尘电场阴极起到良好的支撑作用，并对尾气除尘电场阴极起到相对于尾气除尘电场阳极的固定作用，使尾气除尘电场阴极和尾气除尘电场阳极之间保持设定的距离。而现有技术中，阴极的支撑点在阴极的端点，难以保持阴极和阳极之间的距离。于本发明一实施例中尾气绝缘机构设置在除尘流道外、即第二级流道外，以防止或减少尾气中的灰尘等聚集在尾气绝缘机构上，导致尾气绝缘机构击穿或导电。
于本发明一实施例中尾气绝缘机构采用耐高压陶瓷绝缘子，对尾气除尘电场阴极和尾气除尘电场阳极之间进行绝缘。尾气除尘电场阳极也称作一种外壳。
于本发明一实施例中第三阳极部在气体流动方向上位于阴极支撑板和尾气绝缘机构之前，第三阳极部能够除去尾气中的水，防止水进入尾气绝缘机构，造成尾气绝缘机构短路、打火。另外，第三阳级部能够除去尾气中相当一部分的灰尘，当尾气通过尾气绝缘机构时，相当一部分的灰尘已被消除，减少灰尘造成尾气绝缘机构短路的可能性。于本发明一实施例中尾气绝缘机构包括绝缘瓷柱。第三阳极部的设计，主要是为了保护绝缘瓷柱不被气体中颗粒物等污染，一旦气体污染绝缘瓷柱将会造成尾气除尘电场阳极和尾气除尘电场阴极导通，从而使尾气除尘电场阳极的积尘功能失效，故第三阳极部的设计，能有效减少绝缘瓷柱被污染，提 高产品的使用时间。在尾气流经第二级流道过程中，第三阳极部和尾气除尘电场阴极先接触具有污染性的气体，尾气绝缘机构后接触气体，达到先除尘后经过尾气绝缘机构的目的，减少对尾气绝缘机构造成的污染，延长清洁维护周期，对应电极使用后绝缘支撑。于本发明一实施例中，所述第三阳极部的长度是足够的长，以清除部分灰尘，减少积累在所述尾气绝缘机构和所述阴极支撑板上的灰尘，减少灰尘造成的电击穿。于本发明一实施例中第三阳极部长度占尾气除尘电场阳极总长度的1/10至1/4、1/4至1/3、1/3至1/2、1/2至2/3、2/3至3/4，或3/4至9/10。
于本发明一实施例中第四阳极部在尾气流动方向上位于阴极支撑板和尾气绝缘机构之后。第四阳极部包括积尘段和预留积尘段。其中，积尘段利用静电吸附尾气中的颗粒物，该积尘段是为了增加积尘面积，延长尾气电场装置的使用时间。预留积尘段能为积尘段提供失效保护。预留积尘段是为了在满足设计除尘要求的前提下，进一步提高积尘面积。预留积尘段作为补充前段积尘使用。于本发明一实施例中预留积尘段和第三阳极部可使用不同的电源。
于本发明一实施例中由于尾气除尘电场阴极和尾气除尘电场阳极之间存在极高电位差，为了防止尾气除尘电场阴极和尾气除尘电场阳极导通，尾气绝缘机构设置在尾气除尘电场阴极和尾气除尘电场阳极之间的第二级流道之外。因此，尾气绝缘机构外悬于尾气除尘电场阳极的外侧。于本发明一实施例中尾气绝缘机构可采用非导体耐温材料，比如陶瓷、玻璃等。于本发明一实施例中，完全密闭无空气的材料绝缘要求绝缘隔离厚度>0.3mm/kv；空气绝缘要求>1.4mm/kv。可根据尾气除尘电场阴极和尾气除尘电场阳极之间的极间距的1.4倍设置绝缘距离。于本发明一实施例中尾气绝缘机构使用陶瓷，表面上釉；不能使用胶粘或有机材料填充连接，耐温大于350摄氏度。
于本发明一实施例中尾气绝缘机构包括绝缘部和隔热部。为了使尾气绝缘机构具有抗污功能，绝缘部的材料采用陶瓷材料或玻璃材料。于本发明一实施例中绝缘部可为伞状串陶瓷柱或玻璃柱，伞内外挂釉。伞状串陶瓷柱或玻璃柱的外缘与尾气除尘电场阳极的距离大于电场距离的1.4倍、即大于极间距的1.4倍。伞状串陶瓷柱或玻璃柱的伞突边间距总和大于伞状串陶瓷柱的绝缘间距的1.4倍。伞状串陶瓷柱或玻璃柱的伞边内深总长大于伞状串陶瓷柱的绝缘距离1.4倍。绝缘部还可为柱状串陶瓷柱或玻璃柱，柱内外挂釉。于本发明一实施例中绝缘部还可呈塔状。
于本发明一实施例中，绝缘部内设置加热棒，当绝缘部周围温度接近露点时，加热棒启动并进行加热。由于使用中绝缘部的内外存在温差，绝缘部的内外、外部容易产生凝露。绝缘部的外表面可能自发或被气体加热产生高温，需要必要的隔离防护，防烫伤。隔热部包括 位于第二绝缘部外部的防护围挡板、脱硝净化反应腔。于本发明一实施例中绝缘部的尾部需要凝露位置同样需要隔热，防止环境以及散热高温加热凝露组件。
于本发明一实施例中尾气电场装置的电源的引出线使用伞状串陶瓷柱或玻璃柱过墙式连接，墙内使用弹性碰头连接阴极支撑板，墙外使用密闭绝缘防护接线帽插拔连接，引出线过墙导体与墙绝缘距离大于伞状串陶瓷柱或玻璃柱的陶瓷绝缘距离。于本发明一实施例中高压部分取消引线，直接安装在端头上，确保安全，高压模块整体外绝缘使用ip68防护，使用介质换热散热。
于本发明一实施例中尾气除尘电场阴极和尾气除尘电场阳极之间采用非对称结构。在对称电场中极性粒子受到一个相同大小而方向相反的作用力，极性粒子在电场中往复运动；在非对称电场中，极性粒子受到两个大小不同的作用力，极性粒子向作用力大的方向移动，可以避免产生耦合。
本发明的尾气电场装置的尾气除尘电场阴极和尾气除尘电场阳极之间形成电离除尘电场。为了减少所述电离除尘电场的电场耦合，于本发明一实施例中，减少电场耦合的方法包括如下步骤：选择尾气除尘电场阳极的集尘面积与尾气除尘电场阴极的放电面积的比，使电场耦合次数≤3。于本发明一实施例中尾气除尘电场阳极的集尘面积与尾气除尘电场阴极的放电面积的比可以为：1.667：1-1680：1；3.334：1-113.34：1；6.67：1-56.67：1；13.34：1-28.33：1。该实施例选择相对大面积的尾气除尘电场阳极的集尘面积和相对极小的尾气除尘电场阴极的放电面积，具体选择上述面积比，可以减少尾气除尘电场阴极的放电面积，减小吸力，扩大尾气除尘电场阳极的集尘面积，扩大吸力，即尾气除尘电场阴极和尾气除尘电场阳极间产生不对称的电极吸力，使荷电后粉尘落入尾气除尘电场阳极的集尘表面，虽极性改变但无法再被尾气除尘电场阴极吸走，减少电场耦合，实现电场耦合次数≤3。即在电场极间距小于150mm时电场耦合次数≤3，电场能耗低，能够减少电场对气溶胶、水雾、油雾、松散光滑颗粒物的耦合消耗，节省电场电能30～50％。集尘面积是指尾气除尘电场阳极工作面的面积，比如，若尾气除尘电场阳极呈中空的正六边形管状，集尘面积即为中空的正六边形管状的内表面积，集尘面积也称作积尘面积。放电面积指尾气除尘电场阴极工作面的面积，比如，若尾气除尘电场阴极呈棒状，放电面积即为棒状的外表面积。
于本发明一实施例中尾气除尘电场阳极的长度可以为10～180mm、10～20mm、20～30mm、60～180mm、30～40mm、40～50mm、50～60mm、60～70mm、70～80mm、80～90mm、90～100mm、100～110mm、110～120mm、120～130mm、130～140mm、140～150mm、150～160mm、160～170mm、170～180mm、60mm、180mm、10mm或30mm。尾气除尘电场阳极的长度是指尾气除尘电场 阳极工作面的一端至另一端的最小长度。尾气除尘电场阳极选择此种长度，可以有效减少电场耦合。
于本发明一实施例中尾气除尘电场阳极的长度可以为10～90mm、15～20mm、20～25mm、25～30mm、30～35mm、35～40mm、40～45mm、45～50mm、50～55mm、55～60mm、60～65mm、65～70mm、70～75mm、75～80mm、80～85mm或85～90mm，此种长度的设计可以使尾气除尘电场阳极及尾气电场装置具有耐高温特性，并使得尾气电场装置在高温冲击下具有高效率的集尘能力。
于本发明一实施例中尾气除尘电场阴极的长度可以为30～180mm、54～176mm、30～40mm、40～50mm、50～54mm、54～60mm、60～70mm、70～80mm、80～90mm、90～100mm、100～110mm、110～120mm、120～130mm、130～140mm、140～150mm、150～160mm、160～170mm、170～176mm、170～180mm、54mm、180mm、或30mm。尾气除尘电场阴极的长度是指尾气除尘电场阴极工作面的一端至另一端的最小长度。尾气除尘电场阴极选择此种长度，可以有效减少电场耦合。
于本发明一实施例中尾气除尘电场阴极的长度可以为10～90mm、15～20mm、20～25mm、25～30mm、30～35mm、35～40mm、40～45mm、45～50mm、50～55mm、55～60mm、60～65mm、65～70mm、70～75mm、75～80mm、80～85mm或85～90mm，此种长度的设计可以使尾气除尘电场阴极及尾气电场装置具有耐高温特性，并使得尾气电场装置在高温冲击下具有高效率的集尘能力。其中，当电场温度为200℃时，对应的集尘效率为99.9％；电场温度为400℃时，对应的集尘效率为90％；当电场温度为500℃时，对应的集尘效率为50％。
于本发明一实施例中尾气除尘电场阳极和尾气除尘电场阴极之间的距离可以为5～30mm、2.5～139.9mm、9.9～139.9mm、2.5～9.9mm、9.9～20mm、20～30mm、30～40mm、40～50mm、50～60mm、60～70mm、70～80mm、80～90mm、90～100mm、100～110mm、110～120mm、120～130mm、130～139.9mm、9.9mm、139.9mm、或2.5mm。尾气除尘电场阳极和尾气除尘电场阴极之间的距离也称作极间距。极间距具体是指尾气除尘电场阳极、尾气除尘电场阴极工作面之间的最小垂直距离。此种极间距的选择可以有效减少电场耦合，并使尾气电场装置具有耐高温特性。
鉴于电离除尘的特有性能，电离除尘可适用去除气体中的颗粒物，例如可用于去除发动机尾气中的颗粒物。但是，经过许多大学、研究机构、企业的多年研究，现有电场除尘装置仍然不适合在车辆中使用。首先，现有技术中的电场除尘装置体积过于庞大，较难安装在车辆中。其次，重要的是，现有技术中电场除尘装置只能去除约70％的颗粒物，不能满足许多国家的排放标准。
本发明的发明人研究发现，现有技术中电场除尘装置的缺点是由电场耦合引起的。本发 明通过减小电场耦合次数，可以显著减小电场除尘装置的尺寸(即体积)。比如，本发明提供的电离除尘装置的尺寸约为现有电离除尘装置尺寸的五分之一。原因是，为了获得可接受的颗粒去除率，现有电离除尘装置中将气体流速设为1m/s左右，而本发明在将气体流速提高到6m/s的情况下，仍能获得较高的颗粒去除率。当处理一给定流量的气体时，随着气体速度的提高，电场除尘装置的尺寸可以减小。
另外，本发明可以显著提高颗粒去除效率。例如，在气体流速为1m/s左右时，现有技术电场除尘装置可以去除发动机排气中大约70％的颗粒物，但是本发明可以去除大约99％的颗粒物，即使在气体流速为6m/s时。因此，本发明可以满足最新的排放标准。
由于发明人发现了电场耦合的作用，并且找到了减少电场耦合次数的方法，本发明获得了上述预料不到的结果。所以，本发明可以用来制造适用于车辆的电场除尘装置。
尾气除尘电场阳极和尾气除尘电场阴极之间的电离除尘电场也称作第三电场。于本发明一实施例中尾气除尘电场阳极和尾气除尘电场阴极之间还形成有与第三电场不平行的第四电场。于本发明另一实施例中，所述第四电场与所述电离除尘电场的流道不垂直。第四电场也称作辅助电场，可以通过一个或两个第二辅助电极形成。当第四电场由一个第二辅助电极形成时，该第二辅助电极可以放在电离电场的进口或出口，该第二辅助电极可以带负电势、或正电势。其中，当所述第二辅助电极为阴极时，设置在或靠近所述电离除尘电场的进口；所述第二辅助电极与所述尾气除尘电场阳极具有夹角α，且0°＜α≤125°、或45°≤α≤125°、或60°≤α≤100°、或α＝90°。当所述第二辅助电极为阳极时，设置在或靠近所述电离除尘电场的出口；所述第二辅助电极与所述尾气除尘电场阴极具有夹角α，且0°＜α≤125°、或45°≤α≤125°、或60°≤α≤100°、或α＝90°。当第四电场由两个第二辅助电极形成时，其中一个第二辅助电极可以带负电势，另一个第二辅助电极可以带正电势；一个第二辅助电极可以放在电离除尘电场的进口，另一个第二辅助电极放在电离除尘电场的出口。另外，第二辅助电极可以是尾气除尘电场阴极或尾气除尘电场阳极的一部分，即第二辅助电极可以是由尾气除尘电场阴极或尾气除尘电场阳极的延伸段构成，此时尾气除尘电场阴极和尾气除尘电场阳极的长度不一样。第二辅助电极也可以是一个单独的电极，也就是说第二辅助电极可以不是尾气除尘电场阴极或尾气除尘电场阳极的一部分，此时，第四电场的电压和第三电场的电压不一样，可以根据工作状况单独地控制。
第四电场能给尾气除尘电场阳极和尾气除尘电场阴极之间带负电荷的氧离子流施加朝向电离电场的出口的力，使得尾气除尘电场阳极和尾气除尘电场阴极之间带负电荷的氧离子流具有向出口的移动速度。在尾气流入电离电场，并向电离电场的出口方向流动过程中，带负 电荷的氧离子也在向尾气除尘电场阳极且向电离电场的出口方向移动，且带负电荷的氧离子在向尾气除尘电场阳极且向电离电场的出口移动过程中将与尾气中的颗粒物等相结合，由于氧离子具有向出口的移动速度，氧离子在与颗粒物相结合时，两者间不会产生较强的碰撞，从而避免因较强碰撞而造成较大的能量消耗，保证氧离子易于与颗粒物相结合，并使得气体中的颗粒物的荷电效率更高，进而在尾气除尘电场阳极的作用下，能将更多的颗粒物收集起来，保证尾气电场装置的除尘效率更高。尾气电场装置对顺离子流方向进入电场的颗粒物的收集率比对逆离子流方向进入电场的颗粒物的收集率提高近一倍，从而提高电场的积尘效率，减少电场电耗。另外，现有技术中集尘电场的除尘效率较低的主要原因也是粉尘进入电场方向与电场内离子流方向相反或垂直交叉，从而导致粉尘与离子流相互冲撞剧烈并产生较大能量消耗，同时也影响荷电效率，进而使现有技术中电场集尘效率下降，且能耗增加。尾气电场装置在收集气体中的粉尘时，气体及粉尘顺离子流方向进入电场，粉尘荷电充分，电场消耗小；单极电场集尘效率会达到99.99％。当尾气及粉尘逆离子流方向进入电场，粉尘荷电不充分，电场电耗也会增加，集尘效率会在40％-75％。于本发明一实施例中尾气电场装置形成的离子流有利于无动力风扇流体输送、增氧、或热量交换等。
随着，尾气除尘电场阳极持续收集尾气中的颗粒物等，颗粒物等在尾气除尘电场阳极上堆积并形成碳黑，且碳黑厚度不断增加，使极间距减小。于本发明一实施例中，待检测到电场电流增加，利用电场反电晕放电现象，配合增高电压，限制入注电流，使发生在积碳位置急剧放电产生大量等离子，这些低温等离子使碳黑中有机成分深度氧化，高分子键断裂，形成小分子二氧化碳和水，完成碳黑清洁。由于空气中的氧气同时参与电离，形成臭氧，臭氧分子团同时扑捉沉积的油污分子团，加速油污分子中碳氢键断裂，使部分油分子碳化，以达到尾气挥发份净化目的。另外，碳黑清洁是利用等离子体来达到常规清洗方法无法达到的效果。等离子体是物质的一种状态，也叫做物质的第四态，并不属于常见的固、液、气三态。对气体施加足够的能量使之离化便成为等离子状态。等离子体的“活性”组分包括：离子、电子、原子、活性基团、激发态的核素(亚稳态)、光子等。于本发明一实施例中，当电场积尘时，所述尾气电场装置检测电场电流，采用以下任一方式实现碳黑清洁：
(1)当电场电流增加到一个给定值，所述尾气电场装置增高电场电压。
(2)当电场电流增加到一个给定值，所述尾气电场装置利用电场反电晕放电现象完成碳黑清洁。
(3)当电场电流增加到一个给定值，所述尾气电场装置利用电场反电晕放电现象，增高电压，限制入注电流，完成碳黑清洁。
(4)当电场电流增加到一个给定值，所述尾气电场装置利用电场反电晕放电现象，增高电压，限制入注电流，使发生在阳极积碳位置的急剧放电产生等离子，所述等离子使碳黑有机成分深度氧化，高分子键断裂，形成小分子二氧化碳和水，完成碳黑清洁。

本领域技术人员基于现有技术认为：臭氧处理发动机尾气中氮氧化物NO X时，氮氧化物NO X被臭氧氧化成高价态氮氧化物如NO 2、N 2O 5和NO 3等，所述高价态氮氧化物还是气体，仍然不能从发动机尾气中脱除，即臭氧处理发动机尾气中氮氧化物NO X无效，但是，本申请人却发现臭氧和尾气中氮氧化物反应产生的高价态氮氧化物并不是最后的产物，高价态氮氧化物会和水反应产生硝酸，硝酸则更容易从发动机尾气中脱除，比如使用电凝和冷凝，该效果对所属技术领域的技术人员来说是预料不到的。该预料不到的技术效果是因为本领域技术人员没有认识到臭氧还会和发动机尾气中的VOC反应产生足够水和高价氮氧化物反应产生硝酸。
用臭氧来处理发动机尾气时，臭氧最优先与挥发性有机化合物VOC反应，被氧化成CO 2和水，然后再与氮氧化合物NO X，被氧化成高价态氮氧化物如NO 2、N 2O 5和NO 3等，最后再与一氧化碳CO反应，被氧化成CO 2，即反应优先顺序为挥发性有机化合物VOC＞氮氧化合物NO X＞一氧化碳CO，而且尾气中有足够的挥发性有机化合物VOC产生足够的水可以充分与高价态氮氧化物反应生成硝酸，因此，用臭氧来处理发动机尾气使得臭氧除NO X效果更好，该效果对所属技术领域的技术人员来说是预料不到的技术效果。
臭氧处理发动机尾气可达到如下脱除效果：氮氧化物NO X脱除效率：60～99.97％；一氧化碳CO脱除效率：1～50％；挥发性有机化合物VOC脱除效率：60～99.97％，对所属技术领域的技术人员来说是预料不到的技术效果。
所述高价态氮氧化物与挥发性有机化合物VOC被氧化得到的水反应得到的硝酸更易脱除且脱除得到的硝酸可回收利用，例如可以通过本发明的电凝装置脱除硝酸、也可以通过现有技术中脱除硝酸的方法例如碱洗脱除硝酸。本发明电凝装置包括第一电极和第二电极，含硝酸水雾流经第一电极时，含硝酸水雾将带电，第二电极给带电的含硝酸水雾施加吸引力，含硝酸水雾向第二电极移动，直至含硝酸水雾附着在第二电极上，然后再进行收集，本发明电凝装置对含硝酸水雾的收集能力更强、收集效率更高。
尾气电离除尘时空气中的氧气参与电离，形成臭氧，尾气电离除尘系统与尾气臭氧净化系统结合后，电离形成的臭氧可用于氧化尾气中的污染物，如氮氧化合物NO X、挥发性有机化合物VOC、一氧化碳CO，即电离形成的臭氧可被臭氧处理NO X用来处理污染物，氧化氮氧化合物NO X的同时还会氧化挥发性有机化合物VOC、一氧化碳CO，节省臭氧处理NO X的臭氧消耗量，而且也不需要再增加除臭氧机构对电离形成的臭氧进行消解，不会造成温室效应，破坏大气中的紫外线，可见，尾气电离除尘装置尾气电场系统与尾气臭氧净化系统结合后，在功能上彼此支持，并取得了新的技术效果：电离形成的臭氧被尾气臭氧净化系统用来处理污染物，节省臭氧处理污染物的臭氧消耗量，而且也不需要再增加除臭氧机构对电离形成的臭氧进行消解，不会造成温室效应，破坏大气中的紫外线，具有突出的实质性特点和显著的进步。

于本发明一实施例中电凝装置的第一电极呈线状，第二电极呈面状。于本发明一实施例中第一电极垂直于第二电极。于本发明一实施例中第一电极和第二电极相平行。于本发明一实施例中第一电极和第二电极均呈面状，且第一电极和第二电极相平行。于本发明一实施例中第一电极采用金属丝网。于本发明一实施例中第一电极呈平面状或球面状。于本发明一实施例中第二电极呈曲面状或球面状。于本发明一实施例中第一电极呈点状、线状、或网状，第二电极呈桶状，第一电极位于第二电极的内部，且第一电极位于第二电极的中心对称轴上。
于本发明一实施例中电凝装置的第一电极与电源的一个电极电性连接；第二电极与电源的另一个电极电性连接。于本发明一实施例中第一电极具体与电源的阴极电性连接，第二电极具体与电源的阳极电性连接。
同时，于本发明一些实施例中电凝装置的第一电极可以具有正电势或负电势；当第一电极具有正电势时，第二电极具有负电势；当第一电极具有负电势时，第二电极具有正电势，第一电极和第二电极均与电源电性连接，具体地第一电极和第二电极可分别与电源的正负极电性连接。该电源的电压称作上电驱动电压，上电驱动电压大小的选择与环境温度、介质温度等有关。例如，电源的上电驱动电压范围可以为5～50KV、10～50KV、5～10KV、10～20KV、20～30KV、30～40KV、或40～50KV，从生物电至空间雾霾治理用电。电源可以是直流电源或交流电源，其上电驱动电压的波形可以是直流波形、正弦波、或调制波形。直流电源作为吸 附的基本应用；正弦波作为移动使用，如正弦波的上电驱动电压作用于第一电极和第二电极之间，所产生的电凝电场将驱动电凝电场中带电的粒子、如雾滴等向第二电极移动；斜波作为拉动使用，根据拉动力度需要调制波形，如非对称电凝电场的两端边缘处，对其中的介质所产生的拉力具有明显的方向性，以驱动电凝电场中的介质沿该方向移动。当电源采用交流电源时，其变频脉冲的范围可以为0.1Hz～5GHz、0.1Hz～1Hz、0.5Hz～10Hz、5Hz～100Hz、50Hz～1KHz、1KHz～100KHz、50KHz～1MHz、1MHz～100MHz、50MHz～1GHz、500MHz～2GHz、或1GHz～5GHz，适用生物体至污染物颗粒的吸附。第一电极可作为导线，在与含硝酸的水雾接触时，直接将正负电子导入含硝酸的水雾，此时含硝酸的水雾本身可作为电极。第一电极可通过能量波动的方法使电子转移到含硝酸的水雾或电极上，这样第一电极就可以不接触含硝酸的水雾。含硝酸的水雾在由第一电极向第二电极移动过程中，将重复得到电子和失去电子；与此同时，大量电子在位于第一电极和第二电极之间的多个含硝酸的水雾之间进行传递，使更多雾滴带电，并最终到达第二电极，从而形成电流，该电流也称作上电驱动电流。上电驱动电流的大小与环境温度、介质温度、电子量、被吸附物质量、逃逸量有关。比如，随电子量增加，可移动的粒子、如雾滴增加，由移动的带电粒子形成的电流会随之增加。单位时间内被吸附的带电物质、如雾滴越多，电流越大。逃逸的雾滴只是带了电，但并未到达第二电极，也就是说未形成有效的电中和，从而在相同的条件下，逃逸的雾滴越多，电流越小。相同的条件下，环境温度越高，气体粒子和雾滴速度越快，其自身的动能也就越高，其自身与第一电极和第二电极碰撞机率就会越大，也越不易被第二电极吸附住，从而产生逃逸，但由于其逃逸是发生在电中和之后，且可能是发生了反复多次的电中和之后，从而相应的增加了电子传导速度，电流也就相应增加。同时，由于环境温度越高，气体分子、雾滴等的动量越高，且越不易被第二电极吸附，即使第二电极吸附后，再次从第二电极逃逸、即电中和之后逃逸的机率也越大，因此在第一电极与第二电极的间距不变的情况下，需要增加上述上电驱动电压，该上电驱动电压的极限为达到空气击穿的效果。另外，介质温度的影响基本与环境温度的影响相当。介质温度越低，需激发介质、如雾滴带电的能量小，且其自身所具有的动能也越小，在同样的电凝电场力作用下，越容易被吸附到第二电极上，从而形成的电流较大。电凝装置对冷态的含硝酸的水雾吸附效果更好。而随介质、如雾滴的浓度增加，带电的介质在与第二电极碰撞之前已与其它介质产生电子传递的机率越大，从而形成有效电中和的机会也会越大，形成的电流也相应地会越大；所以当介质浓度越高时，形成的电流越大。上电驱动电压与介质温度的关系与上电驱动电压与环境温度的关系基本相同。
于本发明一实施例中与第一电极和第二电极相连接的电源的上电驱动电压可小于起始起 晕电压。该起始起晕电压为能使第一电极和第二电极之间产生放电并电离气体的最小电压值。对于不同的气体、及不同的工作环境等，起始起晕电压的大小可能会不相同。但对于本领域技术人员来说，针对确定的气体、及工作环境，所对应的起始起晕电压是确定的。于本发明一实施例中电源的上电驱动电压具体可为0.1-2kv/mm。电源的上电驱动电压小于空气电晕起晕电压。
于本发明一实施例中第一电极和第二电极均沿左右方向延伸，第一电极的左端位于第二电极的左端的左方。
于本发明一实施例中第二电极有两个，第一电极位于两个第二电极之间。
第一电极与第二电极之间的距离可根据两者间的上电驱动电压大小、水雾的流速、以及含硝酸的水雾的带电能力等进行设置。比如，第一电极和第二电极的间距可以为5～50mm、5～10mm、10～20mm、20～30mm、30～40mm、或40～50mm。第一电极和第二电极的间距越大，需要的上电驱动电压越高，以形成足够强大的电凝电场，用于驱动带电的介质快速移向第二电极，以免介质逃逸。同样的条件下，第一电极和第二电极的间距越大，顺着气流方向，越靠近中心位置，物质流速越快；越靠近第二电极的物质的流速越慢；而垂直于气流方向，带电介质粒子、如雾粒，随第一电极和第二电极的间距增加，在没有发生碰撞的情况下，被电凝电场加速的时间越长，因此，物质在接近第二电极之前沿垂直方向的移动速度越大。在同样的条件下，如果上电驱动电压不变，随距离增加，电凝电场强度不断减小，电凝电场中介质带电的能力也就越弱。
第一电极和第二电极构成吸附单元。吸附单元可以有一个或多个，具体数量依据实际需要来确定。在一种实施例中，吸附单元有一个。在另一种实施例中吸附单元有多个，以利用多个吸附单元吸附更多的硝酸液，从而提高收集硝酸液的效率。当吸附单元有多个时，全部吸附单元的分布形式可以根据需要灵活进行调整；全部吸附单元可以是相同的，也可以是不同的。比如，全部吸附单元可沿左右方向、前后方向、斜向或螺旋方向中的一个方向或多个方向进行分布，以满足不同风量的要求。全部吸附单元可以呈矩形阵列分布，也可以呈金字塔状分布。上述各种形状的第一电极和第二电极可以自由组合形成吸附单元。例如，线状的第一电极插入管状的第二电极形成吸附单元，再与线状的第一电极组合，形成新的吸附单元，此时两个线状的第一电极可电连接；新的吸附单元再在左右方向、上下方向、斜向或螺旋方向中的一个方向或多个方向进行分布。再例如，线状的第一电极插入管状的第二电极形成吸附单元，此吸附单元在左右方向、上下方向、斜向或螺旋方向中的一个方向或多个方向进行分布，形成新的吸附单元，该新的吸附单元再与上述各种形状的第一电极进行组合，以形成 新的吸附单元。吸附单元中的第一电极和第二电极之间的距离可以任意调整，以适应不同的工作电压和吸附对象的要求。不同的吸附单元之间可以进行组合。不同的吸附单元可以使用同一电源，也可以使用不同的电源。当使用不同的电源时，各电源的上电驱动电压可以是相同的，也可以是不同的。另外，本电凝装置也可以有多个，且全部电凝装置可以沿左右方向、上下方向、螺旋方向或斜向中的一个方向或多个方向进行分布。
于本发明一实施例中电凝装置还包括电凝壳体，该电凝壳体包括电凝进口、电凝出口及电凝流道，电凝流道的两端分别与电凝进口和电凝出口相连通。于本发明一实施例中电凝进口呈圆形，且电凝进口的直径为300～1000mm、或500mm。于本发明一实施例中电凝出口呈圆形，且电凝出口的直径为300～1000mm、或500mm。于本发明一实施例中电凝壳体包括由电凝进口至电凝出口方向依次分布的第一壳体部、第二壳体部、及第三壳体部，电凝进口位于第一壳体部的一端，电凝出口位于第三壳体部的一端。于本发明一实施例中第一壳体部的轮廓大小由电凝进口至电凝出口方向逐渐增大。于本发明一实施例中第一壳体部呈直管状。于本发明一实施例中第二壳体部呈直管状，且第一电极和第二电极安装在第二壳体部中。于本发明一实施例中第三壳体部的轮廓大小由电凝进口至电凝出口方向逐渐减小。于本发明一实施例中第一壳体部、第二壳体部、及第三壳体部的截面均呈矩形。于本发明一实施例中电凝壳体的材质为不锈钢、铝合金、铁合金、布、海绵、分子筛、活性炭、泡沫铁、或泡沫碳化硅。于本发明一实施例中第一电极通过电凝绝缘件与电凝壳体相连接。于本发明一实施例中电凝绝缘件的材质为绝缘云母。于本发明一实施例中电凝绝缘件呈柱状、或塔状。于本发明一实施例中第一电极上设有呈圆柱形的前连接部，且前连接部与电凝绝缘件固接。于本发明一实施例中第二电极上设有呈圆柱形的后连接部，且后连接部与电凝绝缘件固接。
于本发明一实施例中第一电极位于电凝流道中。于本发明一实施例中第一电极的截面面积与电凝流道的截面面积比为99％～10％、或90～10％、或80～20％、或70～30％、或60～40％、或50％。第一电极的截面面积是指第一电极沿截面上实体部分的面积之和。
在收集含硝酸的水雾过程中，含硝酸的水雾由电凝进口进入电凝壳体，并朝向电凝出口处移动；在含硝酸的水雾朝向电凝出口移动过程中，含硝酸的水雾将经过第一电极，并带电；第二电极将带电的含硝酸的水雾吸附住，以将含硝酸的水雾收集在第二电极上。本发明利用电凝壳体引导尾气及含硝酸的水雾流经第一电极，以利用第一电极使硝酸的水雾带电，并利用第二电极收集硝酸的水雾，从而有效降低由电凝出口处流出的硝酸的水雾。于本发明一些实施例中电凝壳体的材质可以是金属、非金属、导体、非导体、水、各类导电液体、各类多孔材料、或各类泡沫材料等。当电凝壳体的材质为金属时，其材质具体可以是不锈钢、或铝 合金等。当电凝壳体的材质是非金属时，其材质具体可以是布、或海绵等。当电凝壳体的材质是导体时，其材质具体可以是铁合金等。当电凝壳体的材质是非导体时，其表面形成水层水即成为电极，如吸水后的沙层。当电凝壳体的材质为水和各类导电液体时，电凝壳体是静止或流动的。当电凝壳体的材质为各类多孔材料时，其材质具体可以是分子筛或活性炭。当电凝壳体的材质为各类泡沫材料时，其材质具体可以是泡沫铁、泡沫碳化硅等。在一种实施例中第一电极通过电凝绝缘件与电凝壳体固接，电凝绝缘件的材质可以为绝缘云母。同时，在一种实施例中第二电极直接与电凝壳体电连接，此种连接方式使得电凝壳体可以与第二电极具有相同的电势，这样电凝壳体也能吸附带电的含硝酸的水雾，电凝壳体也构成一种第二电极。电凝壳体中设有上述电凝流道，第一电极安装在电凝流道中。
当含硝酸的水雾附着在第二电极后，将形成凝露。于本发明一些实施例中第二电极可沿上下方向延伸，这样堆积在第二电极上的凝露达到一定重量时，将在重力的作用下沿第二电极向下流动，并最终汇集在设定位置或装置中，从而实现对附着在第二电极上的硝酸液的回收。本电凝装置可用于制冷除雾。另外，也可以采用外加电凝电场的方式对附着在第二电极上的物质进行收集。对第二电极上的物质收集方向既可以同气流相同，也可以与气流方向不同。在具体实施时，因为是要充分利用重力作用，使第二电极上的水滴或水层尽快流入收集槽中的；同时会尽量利用气流方向及其作用力，来加速第二电极上水流的速度。因此会根据不同的安装条件，以及绝缘的方便性、经济性和可行性等，尽量达到上述目的，不拘束于特定的方向。
另外，当前已有的静电场荷电理论是利用电晕放电，电离氧气，产生大量的负氧离子，负氧离子和粉尘接触，粉尘荷电，荷电后的粉尘被异极吸附。但当遇到含硝酸的水雾等低比电阻物质时，现有的电场吸附作用几乎没有。因低比电阻物质在得电后容易失电，当移动中的负氧离子使低比电阻物质荷电后，低比电阻物质又将很快失电，而负氧离子只移动一次，导致如含硝酸的水雾等低比电阻物质失电后难以再带电，或此种带电方式大大降低了低比电阻物质带电的几率，使得低比电阻物质整体处于不带电状态，这样异极就难以对低比电阻物质持续施加吸附力，最终导致现有的电场对含硝酸的水雾等低比电阻物质的吸附效率极低。上述电凝装置及电凝方法，不是采用荷电方式让水雾带电，而是直接将电子传递给含硝酸的水雾使其带电，在某个雾滴带电又失电后，新的电子将快速由第一电极、并通过其它雾滴传递到该失电的雾滴上，使得雾滴失电后又能快速得电，大大增加了雾滴带电几率，如次重复，使得雾滴整体处于得电状态，并使得第二电极能持续给雾滴施加吸引力，直至吸附住雾滴，从而保证本电凝装置对含硝酸的水雾的收集效率更高。本发明采用的上述使雾滴带电的方法， 不需要使用电晕线、电晕极、或电晕板等，简化了本电凝装置的整体结构，降低了本电凝装置的制造成本。同时，本发明采用上述上电方式，也使得第一电极上的大量电子，将通过雾滴传递给第二电极，并形成电流。当流经本电凝装置的水雾的浓度越大时，第一电极上的电子更容易通过含硝酸的水雾传递给第二电极，更多的电子将在雾滴间传递，使得第一电极和第二电极之间形成的电流更大，并使得雾滴的带电几率更高，且使本电凝装置对水雾的收集效率更高。

如图17所示，本实施例中除尘电场阳极5082呈管状，除尘电场阴极5081呈棒状，除尘电场阴极5081穿设在除尘电场阳极5082中。同时本实施例中上述辅助电极5083也呈管状，辅助电极5083与除尘电场阳极5082构成阳极管5084。阳极管5084的前端与除尘电场阴极5081齐平，阳极管5084的后端向后超出了除尘电场阴极5081的后端，该阳极管5084相比于除尘电场阴极5081向后超出的部分为上述辅助电极5083。即本实施例中除尘电场阳极5082和除尘电场阴极5081的长度相同，除尘电场阳极5082和除尘电场阴极5081在前后方向上位置相对；辅助电极5083位于除尘电场阳极5082和除尘电场阴极5081的后方。这样，辅助电极5083与除尘电场阴极5081之间形成辅助电场，该辅助电场给除尘电场阳极5082和除尘电场阴极5081之间带负电荷的氧离子流施加向后的力，使得除尘电场阳极5082和除尘电场阴极5081间带负电荷的氧离子流具有向后的移动速度。当含有待处理物质的气体由前向后流入阳极管5084，带负电荷的氧离子在向除尘电场阳极5082且向后移动过程中将与待处理物质相结合，由于氧离子具有向后的移动速度，氧离子在与待处理物质相结合时，两者间不会产生较强的碰撞，从而避免因较强碰撞而造成较大的能量消耗，使得氧离子易于与待处理物质相结合，并使得气体中待处理物质的荷电效率更高，进而在除尘电场阳极5082及阳极管5084的作用下，能将更多的待处理物质收集起来，保证本电场装置的除尘效率更高。
另外，如图9所示，本实施例中阳极管5084的后端与除尘电场阴极5081的后端之间具有夹角α，且0°＜α≤125°、或45°≤α≤125°、或60°≤α≤100°、或α＝90°。
本实施例中除尘电场阳极5082、辅助电极5083、及除尘电场阴极5081构成除尘单元，且该除尘单元有多个，以利用多个除尘单元有效提高本电场装置的除尘效率。
本实施例中上述待处理物质可以是呈颗粒状的粉尘，也可以是其它需处理的杂质。
本实施例中上述气体可以是欲进入发动机的气体，或发动机排出的气体。
本实施例中直流电源具体可为直流高压电源。上述除尘电场阴极5081和除尘电场阳极5082之间形成放电电场，该放电电场是一种静电场。在无上述辅助电极5083的情况下，除尘电场阴极5081和除尘电场阳极5082之间电场中离子流沿垂直于电极方向，且在两电极间折返流动，并导致离子在电极间来回折返消耗。为此，本实施例利用辅助电极5083使电极相对位置错开，形成除尘电场阳极5082和除尘电场阴极5081间相对不平衡，这个不平衡会使电场中离子流发生偏转。本电场装置利用辅助电极5083形成能使离子流具有方向性的电场。 本实施例中上述电场装置也称作一种有加速方向电场装置。本电场装置对顺离子流方向进入电场的颗粒物的收集率比对逆离子流方向进入电场的颗粒物的收集率提高近一倍，从而提高电场积尘效率，减少电场电耗。另外，现有技术中集尘电场的除尘效率较低的主要原因也是粉尘进入电场方向与电场内离子流方向相反或垂直交叉，从而导致粉尘与离子流相互冲撞剧烈并产生较大能量消耗，同时也影响荷电效率，进而使现有技术中电场集尘效率下降，且能耗增加。
本实施例中电场装置在用于收集气体中的粉尘时，气体及粉尘顺离子流方向进入电场，粉尘荷电充分，电场消耗小；单极电场集尘效率会达到99.99％。当气体及粉尘逆离子流方向进入电场，粉尘荷电不充分，电场电耗也会增加，集尘效率会在40％-75％。另外，本实施例中电场装置形成的离子流有利于无动力风扇流体输送、增氧、热量交换等。

本实施例中电凝装置还可以用于处理含有酸雾的工业尾气。当电凝装置用于处理含有酸雾的工业尾气时，本实施例中电凝进口3031与排放工业尾气的口相连通。如图22所示，本实施例中电凝装置的工作原理如下：工业尾气由电凝进口3031流入电凝壳体303，并经电凝出口3032流出；在此过程中，工业尾气将流经第一电极301，当工业尾气中的酸雾与第一电极301接触时，或与第一电极301的距离达到一定值时，第一电极301将电子传递给酸雾，酸雾带电，第二电极302给带电的酸雾施加吸引力，酸雾向第二电极302移动，并附着在第二电极302上；由于酸雾具有易带且易失电特性，某个带电的雾滴在向第二电极302移动过程中又将失电，此时其它带电的雾滴又将快速将电子传递给该失电的雾滴，如此重复，雾滴处于持续带电状态，第二电极302就能持续给雾滴施加吸附力，并使得雾滴附着在第二电极302，从而实现对工业尾气中酸雾的去除，避免酸雾直接排放至大气中，并对大气造成污染。 本实施例中上述第一电极301和第二电极302构成吸附单元。且在吸附单元仅有一个的情况下，本实施例中电凝装置能除去工业尾气中80％的酸雾，大大降低了酸雾的排放量，具有显著的环保效果。

如图52所示，本实施例在上述实施例55的基础上，其介质气化腔30711位于尾气通过腔30712中；且介质腔涡扇组件30722位于介质气化腔30711中，并具体位于介质气化腔30711的后端处；尾气腔涡扇组件30723位于尾气通过腔30712中，并具体位于尾气通过腔30712的后端处。介质腔涡扇组件30722和尾气腔涡扇组件30723均安装在涡扇轴30721上。本实施例中尾气腔涡扇组件30723位于介质腔涡扇组件30722的后方。这样，流经尾气通过腔30712的汽车尾气将直接作用于尾气腔涡扇组件30723，以带动尾气腔涡扇组件30723及涡扇轴30721转动；同时，当汽车尾气流经尾气通过腔30712时，将与介质气化腔30711中的液体进行换热，并使介质气化腔30711中的液体形成蒸气，该蒸气的压力作用于介质腔涡扇组件30722，以带动介质腔涡扇组件30722及涡扇轴30721转动，从而进一步加快推动涡扇轴30721转动；涡扇轴30721转动时将带动与其相连接的发电机转子30732一起转动，进而利用发电单元3073实现发电。另外，介质气化腔30711中的蒸气在向后流经介质腔涡扇组件30722后，将流入介质循环回路3076，并经介质循环回路3076中的冷凝器30761冷凝为液体后，再重新注入介质气化腔30711，以实现换热介质的循环回收利用。尾气通过腔30712中的汽车尾气在流经尾气腔涡扇组件30723后排放至大气。
另外，本实施例中介质气化腔30711的侧壁上设有弯折段307111，该弯折段307111能有效增加介质气化腔30711与尾气通过腔30712的接触面积，即换热面积。本实施例中弯折段307111的截面呈锯齿状。
实施例57
为提高发动机热效率，需要把发动机尾气热能和背压回收换能，达到高效率，特别是混动车辆，既要燃油直接带动发电机，也要尾热高效转换为电能，这样燃油热效率可以提高15％-20％。对于混动车辆来说，在节省燃油同时可以为电池组件充更多的电，燃油转换为电能的效率可以达到70％以上。
具体地，在混动车辆燃油发动机的排气口，安装上述实施例55或实施例56中尾气降温装置，开启燃油发动机，发动机尾气进入尾气通过腔30712，在尾气背压作用下，经尾气腔导流扇307231调整方向，直接推动尾气腔动力扇307232旋转，从而在涡扇轴30721上产生旋转扭矩。由于存在转动惯量介质腔动力扇307222和尾气腔动力扇307232继续旋转时，将产生抽气，使发动机排气处于瞬时负压，这样，发动机排气阻力极低，有利于发动机继续排气并做功。同样燃油供给和输出负载情况下，提升发动机转速3％-5％左右。
发动机排气温度会因为翘片导热集聚在介质气化腔30711，当集聚温度大于水的沸点温度时，将水注入介质气化腔30711，水瞬间汽化，体积急剧膨胀，通过介质腔导流扇导向， 推动介质腔动力扇307222及涡扇轴30721进一步加速旋转，产生更大的转动惯量和转矩。继续提升发动机转速，而燃油并没有增加，负载也没有减轻，获得的额外转速提升10％-15％。在转速因回收背压和温度提升同时，发动机动力输出将增加，根据排气温度差异，提高功率输出13％-20％左右，对于提高燃油经济性、减少发动机体积来说，非常有帮助。
实施例58
本实施例将实施例55或实施例56中的尾气降温装置应用于一台13升柴油发动机上，该柴油发动机尾气温度为650摄氏度，流量约4000立方米/小时，尾气热量约80千瓦左右。同时，本实施例使用水为换热介质，本尾气降温装置可以回收20千瓦电能，可以用于驱动车载电器。因此，本实施例中尾气降温装置既可以提高燃油经济性，还可以把尾气温度降低到露点以下，有利于需要低温环境的静电除尘、湿电除尘及臭氧脱硝尾气净化工艺的实施；同时实现了发动机变扭连续高效制动和强制连续制动。
具体地，本实施例的尾气降温装置直接连接在一台13升柴油发动机的排气口，并通过在本尾气降温装置的出口、即上述尾气通过腔30712的出口连接尾气电场装置、尾气湿电除尘和臭氧脱硝系统，就能够实现尾热发电、尾气降温、发动机制动、除尘、脱硝等。本实施例中尾气降温装置安装在尾气电场装置的前方。
其中，本实施例使用3寸的介质腔动力扇307222和尾气腔动力扇307232，并使用10kw高速直流发电电动机，电池组件采用48v300ah动力电池组，使用发电电动手动切换开关。初始状态时，发动机怠速运转，转速小于750转，发动机输出功率10％左右，通过发动机排气推动尾气腔动力扇307232旋转，转速在2000转左右，实现尾气压力直接换能；尾气腔动力扇307232以及涡扇轴30721的转动惯量使尾气排气瞬时负压；由于尾气腔动力扇307232转动，在排气管道内产生瞬时负压-80kp左右，通过调节发电电流，改变发电功输出，从而调节尾气排放阻力，适应发动机做功工况，获得发电功率0.1-1.2kw。
当带负载30％时，发动机转速上升到1300转，尾气温度连续高于300摄氏度，向介质气化腔30711注入水，尾气温度下降到200摄氏度，产生大量高温高压蒸气，吸收尾气温度同时产生蒸气动力，由于介质腔导流扇和喷口限制，喷到介质腔动力扇上的蒸气压力继续加速推动介质腔动力扇转动，使介质腔动力扇及涡扇轴转动更快，力矩更大，带动发电机高速大扭矩旋转，通过调节发动电流或励磁电流平衡发动做功和排气背压平衡，获得发电量1kw-3kw，通过调节注入水量，适应排气温度变化，达到恒定排气温度目的，从而获得连续排气温度150摄氏度。低温排气有利于后续尾气电场装置回收颗粒物和臭氧脱硝，达到环保目的。
当发动机停止供油时，通过涡扇轴30721拖动发动机压气，发动机压气通过排气管路到 达尾气腔动力扇307232，推动尾气腔动力扇307232，将压力转变为涡扇轴30721旋转动力，在涡扇轴30721上同时安装的发电机，通过调节发电电流，改变通过涡扇的排气量，从而改变排气阻力大小，实现发动机制动和制动力缓释，可以获得3-10kw左右的制动力，同时回收1-5kw的发电量。
当发电机切换到电动制动模式时，发电机瞬间变成电动机，等于驾驶员快速踏下制动踏板。这时发动机压气通过尾气腔动力扇307232，推动尾气腔动力扇307232正向转动。开启电动机，输出反向转动力矩，通过涡扇轴30721传递到介质腔动力扇307222和尾气腔动力扇307232上，形成强烈反推阻力，进一步增加制动效果。大量压气做功将能耗转变为高温气体，使腔体热量蓄积，同时使发动机制动力增加，强制制动。强制制动功率15-30kw。这种制动可以间歇发电，发电功率3-5kw左右。
当使用电动反推制动同时间歇发电时，突然需要紧急制动，可以停止发电，将制动热量产生蒸气用于制动，连续压气制动蓄积热量传递给介质气化腔中的水，介质气化腔中产生的蒸气通过反推涵道，输出到介质腔动力扇307222上，且蒸气反推介质腔动力扇307222，强制介质腔动力扇307222和尾气腔动力扇307232反转，实现强制制动，可产生制动功率30kw以上。
综上所述，本发明的尾气降温装置能够基于汽车尾气实现余热发电，且热能转换效率高，换热介质可循环利用；能够应用于柴油发动机、汽油发动机和燃气发动机等的节能减排领域，使发动机废热得到回收利用，从而提高发动机的经济性；通过高速涡扇抽气产生恒定排气负压，减少了发动机的排气阻力，提了高发动机效率。所以，本发明有效克服了现有技术中的种种缺点而具高度产业利用价值。

实施例61
如图57所示，本实施例提供一种电场装置，包括依次相通的电场装置入口3085、流道3086、电场流道3087、及电场装置出口3088，流道3086中安装有前置电极3083，前置电极3083的截面面积与流道3086的截面面积比为99％～10％，电场装置还包括除尘电场阴极3081和除尘电场阳极3082，电场流道3087位于除尘电场阴极3081和除尘电场阳极3082之间。本实施例中电场装置的工作原理为：含污染物的气体通过电场装置入口3085进入流道3086，安装在流道3086中的前置电极3083将电子传导给部分污染物，部分污染物带电，当污染物由流道3086进入电场流道3087后，除尘电场阳极3082给已带电的污染物施加吸引力，带电的污染物向除尘电场阳极3082移动，直至该部分污染物附着在除尘电场阳极3082上，同时，电场流道3087中除尘电场阴极3081和除尘电场阳极3082之间形成电离除尘电场，该电离除尘电场将使另一部分未带电的污染物带电，这样另一部分污染物在带电后同样会受到除尘电场阳极3082施加的吸引力，并最终附着在除尘电场阳极3082上，从而利用上述电场装置使污染物带电效率更高，带电更充分，进而保证除尘电场阳极3082能收集更多的污染物，并保证本电场装置对污染物的收集效率更高。
前置电极3083的截面面积是指前置电极3083沿截面上实体部分的面积之和。另外，前置电极3083的截面面积与流道3086的截面面积比可以为99％～10％、或90～10％、或80～20％、或70～30％、或60～40％、或50％。
如图57所示，本实施例中前置电极3083和除尘电场阴极3081均与直流电源的阴极电性连接，除尘电场阳极3082与直流电源的阳极电性连接。本实施例中前置电极3083和除尘电场阴极3081均具有负电势，除尘电场阳极3082具有正电势。
如图57所示，本实施例中前置电极3083具体可呈网状。这样，当气体流经流道3086时， 利用前置电极3083呈网状的结构特点，便于气体及污染物流过前置电极3083，并使气体中污染物与前置电极3083接触更加充分，从而使前置电极3083能将电子传导给更多的污染物，并使污染物的带电效率更高。
如图57所示，本实施例中除尘电场阳极3082呈管状，除尘电场阴极3081呈棒状，除尘电场阴极3081穿设在除尘电场阳极3082中。本实施例中除尘电场阳极3082和除尘电场阴极3081呈非对称结构。当气体流入除尘电场阴极3081和除尘电场阳极3082之间形的电离电场将使污染物带电，且在除尘电场阳极3082施加的吸引力作用下，将带电的污染物收集在除尘电场阳极3082的内壁上。
另外，如图57所示，本实施例中除尘电场阳极3082和除尘电场阴极3081均沿前后方向延伸，除尘电场阳极3082的前端沿前后方向上位于除尘电场阴极3081的前端的前方。且如图57所示，除尘电场阳极3082的后端沿前后方向上位于除尘电场阴极3081的后端的后方。本实施例中除尘电场阳极3082沿前后方向上的长度更长，使得位于除尘电场阳极3082内壁上的吸附面面积更大，从而对带有负电势的污染物的吸引力更大，并能收集更多的污染物。
如图57所示，本实施例中除尘电场阴极3081和除尘电场阳极3082构成电离单元，电离单元有多个，以利用多个电离单元收集更多的污染物，并使得本电场装置对污染物的收集能力更强，且收集效率更高。
本实施例中上述污染物包括导电性较弱的普通粉尘等、及导电性较强的金属粉尘、雾滴、气溶胶等。本实施例中电场装置，对气体中导电性较弱的普通粉尘，及导电性较强的污染物的收集过程为：当气体通过电场装置入口3085流入流道3086中，气体中导电性较强的金属粉尘、雾滴、或气溶胶等污染物在与前置电极3083相接触时，或与前置电极3083的距离达到一定范围时会直接带负电，随后，全部污染物随气流进入电场流道3087，除尘电场阳极3082给已带负电的金属粉尘、雾滴、或气溶胶等施加吸引力，并将该部分污染物收集起来，同时，除尘电场阳极3082与除尘电场阴极3081形成电离电场，该电离电场通过电离气体中的氧获得氧离子，且带负电荷的氧离子在与普通粉尘结合后，使普通粉尘带负电荷，除尘电场阳极3082给该部分带负电荷的粉尘施加吸引力，并将该部分污染物收集起来，从而将气体中导电性较强和导电性较弱的污染物均收集起来，并使得本电场装置所能收集物质的种类更广泛，且收集能力更强。
本实施例中上述除尘电场阴极3081也称作电晕荷电电极。上述直流电源具体为直流高压电源。前置电极3083和除尘电场阳极3082之间通入直流高压，形成导电回路；除尘电场阴极3081和除尘电场阳极3082之间通入直流高压，形成电离放电电晕电场。本实施例中前置 电极3083为密集分布的导体。当容易带电的粉尘经过前置电极3083时，前置电极3083直接将电子给粉尘，粉尘带电，随后被异极的除尘电场阳极3082吸附；同时未带电的粉尘经过除尘电场阴极3081和除尘电场阳极3082形成的电离区，电离区形成的电离氧会把电子荷电给粉尘，这样粉尘继续带电，并被异极的除尘电场阳极3082吸附。
本实施例中电场装置能形成两种及两种以上的上电方式。比如，在气体中氧气充足情况下，可利用除尘电场阴极3081和除尘电场阳极3082之间形成的电离放电电晕电场，电离氧，来使污染物荷电，再利用除尘电场阳极3082收集污染物；而在气体中氧气含量过低、或无氧状态、或污染物为导电尘雾等时，利用前置电极3083直接使污染物上电，让污染物充分带电后被除尘电场阳极3082吸附。本电场装置让电场可以收集各类粉尘同时，也可以应用在各种含氧量尾气环境中，扩大了集尘电场治理粉尘应用范围，提高了集尘效率。本实施例采用上述两种带电方式的电场，可以同时收集容易荷电的高阻值粉尘以及容易上电的低阻值金属粉尘、气溶胶、液雾等。两种上电方式同时使用，电场适用范围扩大。
本实施例中电场装置可应用于进气除尘系统和尾气除尘系统中。当本实施例中电场装置应用于进气除尘系统中时，该电场装置也称作进气电场装置，前置电极3083也称作进气前置电极，除尘电场阳极3082也称作进气除尘电场阳极，除尘电场阴极3081也称作进气除尘电场阴极，流道3086也称作进气流道。当本实施例中电场装置应用于尾气除尘系统中时，该电场装置也称作尾气电场装置，前置电极3083也称作尾气前置电极，除尘电场阳极3082也称作尾气除尘电场阳极，除尘电场阴极3081也称作尾气除尘电场阴极，流道3086也称作尾气流道。
综上所述，本发明有效克服了现有技术中的种种缺点而具高度产业利用价值。
