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。
于本发明的一实施例中的发动机进气除尘系统包括离心分离机构。于本发明一实施例中离心分离机构包括气流转向通道，该气流转向通道能改变气流的流动方向。当含有颗粒物的气体流经气流转向通道时，气体的流动方向将发生改变；而气体中的颗粒物等将在惯性作用下继续沿原方向移动，直至与气流转向通道的侧壁、即离心分离机构的内壁发生碰撞，颗粒 物无法沿原方向继续移动，且在重力作用下向下掉落，这样，颗粒物就从气体中分离出来。

在工作时，在带污染物的气体进入进气除尘电场阳极和进气除尘电场阴极形成的进气电离除尘电场之前，且带污染物的气体通过进气前置电极时，进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进气电离除尘电场时，进气除尘电场阳极给带电的污染物施加吸引力，使污染物向进气除尘电场阳极移动，直至污染物附着在进气除尘电场阳极上。
于本发明一实施例中进气前置电极将电子导入污染物，电子在位于进气前置电极和进气除尘电场阳极之间的污染物之间进行传递，使更多污染物带电。进气前置电极和进气除尘电场阳极之间通过污染物传导电子、并形成电流。
于本发明一实施例中进气前置电极通过与污染物接触的方式使污染物带电。于本发明一 实施例中进气前置电极通过能量波动的方式使污染物带电。于本发明一实施例中进气前置电极通过与污染物接触的方式将电子转移到污染物上，并使污染物带电。于本发明一实施例中进气前置电极通过能量波动的方式将电子转移到污染物上，并使污染物带电。

于本发明一实施例中进气电场装置包括进气流道，进气前置电极位于进气流道中。于本发明一实施例中进气前置电极的截面面积与进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％。进气前置电极的截面面积是指进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进气前置电极带负电势。

于本发明一实施例中进气电场装置入口与分离机构的排气口相连通。
于本发明一实施例中进气电场装置可包括进气除尘电场阴极和进气除尘电场阳极，进气除尘电场阴极与进气除尘电场阳极之间形成电离除尘电场。气体进入电离除尘电场，气体中的氧离子将被电离，并形成大量带有电荷的氧离子，氧离子与气体中粉尘等颗粒物结合，使 得颗粒物荷电，进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进气除尘电场阳极上，以清除掉气体中的颗粒物。

于本发明一实施例中，所述进气除尘电场阴极包括若干阴极棒。于本发明一实施例中，所述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进气除尘电场阳极的形状进行调整，例如，若进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；若进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，进气除尘电场阴极穿设于进气除尘电场阳极内。
于本发明一实施例中，进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进气除尘电场阳极。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，进气除尘电场阳极和进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，进气除尘电场阴极安装在阴极支撑板上，阴极支撑板与进气除尘电场阳极通过进气绝缘机构相连接。所述进气绝缘机构用于实现所述阴极支撑板和所述进气除尘电场阳极之间的绝缘。于本发明一实施例中，进气除尘电场阳极包括第一阳极部和第二阳极部，即所述第一阳极部靠近进气电场装置入口，第二阳极部靠近进气电场装置出口。阴极支撑板和进气绝缘机构在第一阳极部和第二阳极部之间，即进气绝缘机构安装在电离电场中间、或进气除尘电场阴极中间，可以对进气除尘电场阴极起到良好的支撑作用，并对进气 除尘电场阴极起到相对于进气除尘电场阳极的固定作用，使进气除尘电场阴极和进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进气绝缘机构设置在电场流道外、即第二级流道外，以防止或减少气体中的灰尘等聚集在进气绝缘机构上，导致进气绝缘机构击穿或导电。
于本发明一实施例中，进气绝缘机构采用耐高压陶瓷绝缘子，对进气除尘电场阴极和进气除尘电场阳极之间进行绝缘。进气除尘电场阳极也称作一种外壳。
于本发明一实施例中，第一阳极部在气体流动方向上位于阴极支撑板和进气绝缘机构之前，第一阳极部能够除去气体中的水，防止水进入进气绝缘机构，造成进气绝缘机构短路、打火。另外，第一阳级部能够除去气体中相当一部分的灰尘，当气体通过进气绝缘机构时，相当一部分的灰尘已被消除，减少灰尘造成进气绝缘机构短路的可能性。于本发明一实施例中进气绝缘机构包括绝缘瓷柱。第一阳极部的设计，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进气除尘电场阳极和进气除尘电场阴极导通，从而使进气除尘电场阳极的积尘功能失效，故第一阳极部的设计，能有效减少绝缘瓷柱被污染，提高产品的使用时间。在气体流经第二级流道过程中，第一阳极部和进气除尘电场阴极先接触具有污染性的气体，进气绝缘机构后接触气体，达到先除尘后经过进气绝缘机构的目的，减少对进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。所述第一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一阳极部长度占进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，第二阳极部在气体流动方向上位于阴极支撑板和进气绝缘机构之后。第二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气体中的颗粒物，该积尘段是为了增加积尘面积，延长进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，提高除尘效果。预留积尘段作为补充前段积尘使用。于本发明一实施例中，第一阳极部和第二阳极部可使用不同的电源。
于本发明一实施例中，由于进气除尘电场阴极和进气除尘电场阳极之间存在极高电位差，为了防止进气除尘电场阴极和进气除尘电场阳极导通，进气绝缘机构设置在进气除尘电场阴极和进气除尘电场阳极之间的第二级流道之外。因此，进气绝缘机构外悬于进气除尘电场阳极的外侧。于本发明一实施例中进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。可根据进气除尘电场阴极和进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进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，进气绝缘机构包括绝缘部和隔热部。为了使进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进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进气除尘电场阴极和进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。
本发明的进气电场装置的进气除尘电场阴极和进气除尘电场阳极之间形成电离除尘电场。为了减少电离除尘电场发生电场耦合，于本发明一实施例中，减少电场耦合的方法包括如下步骤：选择进气除尘电场阳极的集尘面积与进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进气除尘电场阳极的集尘面积与进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进气除尘电场阳极的集尘面积和相对极小的进气除尘电场阴极的 放电面积，具体选择上述面积比，可以减少进气除尘电场阴极的放电面积，减小吸力，扩大进气除尘电场阳极的集尘面积，扩大吸力，即进气除尘电场阴极和进气除尘电场阳极间产生不对称的电极吸力，使荷电后粉尘落入进气除尘电场阳极的集尘表面，虽极性改变但无法再被进气除尘电场阴极吸走，并减少电场耦合，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％。集尘面积是指进气除尘电场阳极工作面的面积，比如，若进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。放电面积指进气除尘电场阴极工作面的面积，比如，若进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进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。进气除尘电场阳极的长度是指进气除尘电场阳极工作面的一端至另一端的最小长度。进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进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进气除尘电场阳极及进气电场装置具有耐高温特性，并使得进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进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。进气除尘电场阴极的长度是指除尘电场阴极工作面的一端至另一端的最小长度。进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进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进气除尘电场阴极及进气电场装置具有耐高温特性，并使得进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进气除尘电场阳极和进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。进气除尘电场阳极和进气除尘电场阴极之间的距离也称作极间距。极间距具体是指进气除尘电场阳极、进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，并使进气电场装置具有耐高温特性。
于本发明一实施例中，所述除尘电场阴极直径为1-3毫米，所述除尘电场阳极与所述除尘电场阴极的极间距为2.5-139.9毫米；所述除尘电场阳极的积尘面积与所述除尘电场阴极的放电面积的比为1.667：1-1680：1。
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。但是，经过许多大学、研究机构、企业的多年的研究，现有电场除尘装置只能去除约70％的颗粒物，不能满足许多行业的需要。另外，现有技术中的电场除尘装置体积过于庞大。
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。
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。
进气除尘电场阳极和进气除尘电场阴极之间的电离除尘电场也称作第一电场。于本发明一实施例中进气除尘电场阳极和进气除尘电场阴极之间还形成有与第一电场不平行的第二电场。于本发明另一实施例中，所述第二电场与所述电离除尘电场的流道不垂直。第二电场也称作辅助电场，可以通过一个或两个第一辅助电极形成当第二电场由一个第一辅助电极形成时，该第一辅助电极可以放在电离除尘电场的进口或出口，该第一辅助电极可以带负电势、或正电势。其中，当所述第一辅助电极为阴极时，设置在或靠近所述电离除尘电场的进口；所述第一辅助电极与所述进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°。当所述第一辅助电极为阳极时，设置在或靠近所述电离除尘电场的出口；所述第一辅助电极与所述进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°。当第二电场由两个第一辅助电极形成时，其中一个第一辅助电极可以带负电势，另一个第一辅助电极可以带正电势；一个第一辅助电极可以放在电离电场的进口，另一个第一辅助电极放在电离电场的出口。另外，第一辅助电极可以是进气除尘电场阴极或进气除尘电场阳极的一部分，即第一辅助电极可以是由进气除尘电场阴极或进气除尘电场阳极的延伸段构成，此时进气除尘电场阴极和进气除尘电场阳极的长度不一样。第一辅助电极也可以是一个单独的电极，也就是说第一辅助电极可以不是进气除尘电场阴极或进气除尘电场阳极的一部分，此时，第二电场的电压和第一电场的电压不一样，可以根据工作状况单独地控制。
第二电场能给进气除尘电场阳极和进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，使得进气除尘电场阳极和进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。在气体流入电离电场，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进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进气除尘电场阳极且向电离电场的出口移动过程中将与气体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，进而在进气除尘电场阳极的作用下，能将更多的颗粒物收集起来，保证进气电场装置的除尘效率更高。进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。进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％。于本发明一实施例中进气电场装置形成的离子流有利于无动力风扇流体输送、进气增氧、或热量交换等。

实施例16
本实施例中发动机进气系统，包括上述实施例12、实施例13、实施例14或实施例15中的电场装置。欲进入发动机的气体需先流经该电场装置，以利用该电场装置有效地将气体中的粉尘等待处理物质清除掉；随后，经处理后的气体再进入发动机，以保证进入发动机的气体更加干净，所含粉尘等杂质较少；进而保证发动机的工作效率更高，且发动机排放气体中所含污染物更少。该发动机进气系统也称作进气装置。
实施例17
本实施例中电场装置可应用于进气系统，包括除尘电场阴极5081和除尘电场阳极5082分别与直流电源的阴极和阳极电性连接，辅助电极5083与直流电源的阳极电性连接。本实施例中除尘电场阴极5081具有负电势，除尘电场阳极5082和辅助电极5083均具有正电势。
同时，如图13所示，本实施例中辅助电极5083与除尘电场阳极5082固接。在除尘电场阳极5082与直流电源的阳极电性连接后，也实现了辅助电极5083与直流电源的阳极电性连接，且辅助电极5083与除尘电场阳极5082具有相同的正电势。
如图13所示，本实施例中辅助电极5083可沿前后方向延伸，即辅助电极5083的长度方向可与除尘电场阳极5082的长度方向相同。
如图13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13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。

本实施例中电场装置可应用于进气系统，包括除尘电场阴极5081和除尘电场阳极5082分别与直流电源的阴极和阳极电性连接，辅助电极5083与直流电源的阴极电性连接。本实施例中辅助电极5083和除尘电场阴极5081均具有负电势，除尘电场阳极5082具有正电势。
本实施例中辅助电极5083可与除尘电场阴极5081固接。这样，在实现除尘电场阴极5081与直流电源的阴极电性连接后，也实现了辅助电极5083与直流电源的阴极电性连接。同时，本实施例中辅助电极5083沿前后方向延伸。
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也棒状，且辅助电极5083和除尘电场阴极5081构成阴极棒。该阴极棒的前端向前超出除尘电场阳极5082的前端，该阴极棒与除尘电场阳极5082相比向前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的前方。这样，辅助电极5083与除尘电场阳极5082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管状的除尘电场阳极5082，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。
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。
实施例19
如图14所示，本实施例中电场装置可应用于进气系统，辅助电极5083沿左右方向延伸。本实施例中辅助电极5083的长度方向与除尘电场阳极5082和除尘电场阴极5081的长度方向不同。且辅助电极5083具体可与除尘电场阳极5082相垂直。
本实施例中除尘电场阴极5081和除尘电场阳极5082分别与直流电源的阴极和阳极电性连接，辅助电极5083与直流电源的阳极电性连接。本实施例中除尘电场阴极5081具有负电势，除尘电场阳极5082和辅助电极5083均具有正电势。
如图14所示，本实施例中除尘电场阴极5081和除尘电场阳极5082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除尘电场阳极5082和除尘电场阴极5081之间的电场，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。
实施例20
如图15所示，本实施例中电场装置可应用于进气系统，辅助电极5083沿左右方向延伸。本实施例中辅助电极5083的长度方向与除尘电场阳极5082和除尘电场阴极5081的长度方向不同。且辅助电极5083具体可与除尘电场阴极5081相垂直。
本实施例中除尘电场阴极5081和除尘电场阳极5082分别与直流电源的阴极和阳极电性连接，辅助电极5083与直流电源的阴极电性连接。本实施例中除尘电场阴极5081和辅助电极5083均具有负电势，除尘电场阳极5082具有正电势。
如图15所示，本实施例中除尘电场阴极5081和除尘电场阳极5082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的前方。这样，辅助电极 5083与除尘电场阳极5082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除尘电场阳极5082和除尘电场阴极5081之间的电场，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。
实施例21
本实施例中发动机进气装置，包括上述实施例17、18、19、或20中的电场装置。欲进入发动机的气体需先流经该电场装置，以利用该电场装置有效地将气体中的粉尘等待处理物质清除掉；随后，经处理后的气体再进入发动机，以保证进入发动机的气体更加干净，所含粉尘等杂质较少；进而保证发动机的工作效率更高，且发动机排放气体中所含污染物更少。本实施例中发动机进气装置也简称进气装置，电场装置也称作进气电场装置，除尘电场阴极5081也称作进气除尘电场阴极，除尘电场阳极5082也称作进气除尘电场阳极。
实施例22(进气前置电极)
如图16所示，本实施例提供一种进气电场装置，包括依次相通的进气电场装置入口3085、进气流道3086、电场流道3087、及进气电场装置出口3088，进气流道3086中安装有进气前置电极3083，进气前置电极3083的截面面积与进气流道3086的截面面积比为99％～10％，进气电场装置还包括进气除尘电场阴极3081和进气除尘电场阳极3082，电场流道3087位于进气除尘电场阴极3081和进气除尘电场阳极3082之间。本发明进气电场装置的工作原理为：含污染物的气体通过进气电场装置入口3085进入进气流道3086，安装在进气流道3086中的进气前置电极3083将电子传导给部分污染物，部分污染物带电，当污染物由进气流道3086进入电场流道3087后，进气除尘电场阳极3082给已带电的污染物施加吸引力，带电的污染物向进气除尘电场阳极3082移动，直至该部分污染物附着在进气除尘电场阳极3082上，同时，电场流道3087中进气除尘电场阴极3081和进气除尘电场阳极3082之间形成进气电离除尘电场，该进气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进气除尘电场阳极3082施加的吸引力，并最终附着在进气除尘电场阳极3082，从而利用上述进气电场装置使污染物带电效率更高，带电更充分，进而保证进气除尘电场阳 极3082能收集更多的污染物，并保证本发明进气电场装置对污染物的收集效率更高。
进气前置电极3083的截面面积是指进气前置电极3083沿截面上实体部分的面积之和。另外，进气前置电极3083的截面面积与进气流道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16所示，本实施例中进气前置电极3083和进气除尘电场阴极3081均与直流电源的阴极电性连接，进气除尘电场阳极3082与直流电源的阳极电性连接。本实施例中进气前置电极3083和进气除尘电场阴极3081均具有负电势，进气除尘电场阳极3082具有正电势。
如图16所示，本实施例中进气前置电极3083具体可呈网状。这样，当气体流经进气流道3086时，利用进气前置电极3083呈网状的结构特点，便于气体及污染物流过进气前置电极3083，并使气体中污染物与进气前置电极3083接触更加充分，从而使进气前置电极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16所示，本实施例中进气除尘电场阳极3082呈管状，进气除尘电场阴极3081呈棒状，进气除尘电场阴极3081穿设在进气除尘电场阳极3082中。本实施例中进气除尘电场阳极3082和进气除尘电场阴极3081呈非对称结构。当气体流入进气除尘电场阴极3081和进气除尘电场阳极3082之间形的电离电场将使污染物带电，且在进气除尘电场阳极3082施加的吸引力作用下，将带电的污染物收集在进气除尘电场阳极3082的内壁上。
另外，如图16所示，本实施例中进气除尘电场阳极3082和进气除尘电场阴极3081均沿前后方向延伸，进气除尘电场阳极3082的前端沿前后方向上位于进气除尘电场阴极3081的前端的前方。且如图16所示，进气除尘电场阳极3082的后端沿前后方向上位于进气除尘电场阴极3081的后端的后方。本实施例中进气除尘电场阳极3082沿前后方向上的长度更长，使得位于进气除尘电场阳极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16所示，本实施例中进气除尘电场阴极3081和进气除尘电场阳极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，并使得本进气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。本实施例中进气电场装置，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：当气体通过进气电场装置入口3085流入进气流道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进气前置电极3083相接触时，或与进气前置电极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，进气除尘电场阳极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，进气除尘电场阳极3082与进气除尘电场阴极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，进气除尘电场阳极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，并使得本进气电场装置所能收集物质的种类更广泛，且收集能力更强。
本实施例中上述进气除尘电场阴极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。进气前置电极3083和进气除尘电场阳极3082之间通入直流高压，形成导电回路；进气除尘电场阴极3081和进气除尘电场阳极3082之间通入直流高压，形成电离放电电晕电场。本实施例中进气前置电极3083为密集分布的导体。当容易带电的粉尘经过进气前置电极3083时，进气前置电极3083直接将电子给粉尘，粉尘带电，随后被异极的进气除尘电场阳极3082吸附；同时未带电的粉尘经过进气除尘电场阴极3081和进气除尘电场阳极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，并被异极的进气除尘电场阳极3082吸附。
本实施例中进气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，可利用进气除尘电场阴极3081和进气除尘电场阳极3082之间形成的电离放电电晕电场，电离氧，来使污染物荷电，再利用进气除尘电场阳极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，利用进气前置电极3083直接使污染物上电，让污染物充分带电后被进气除尘电场阳极3082吸附。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。
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。
上述实施例仅例示性说明本发明的原理及其功效，而非用于限制本发明。任何熟悉此技术的人士皆可在不违背本发明的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本发明所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本发明的权利要求所涵盖。
