于本发明一实施例中,电场阴极安装在阴极支撑板上,阴极支撑板与电场阳极通过绝缘机构相连接。所述绝缘机构用于实现所述阴极支撑板和所述电场阳极之间的绝缘。于本发明一实施例中,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电场装置入口,第二阳极部靠近电场装置出口。阴极支撑板和绝缘机构在第一阳极部和第二阳极部之间,即绝缘机构安装在电离电场中间、或电场阴极中间,可以对电场阴极起到良好的支撑作用,并对电场阴极起到相对于电场阳极的固定作用,使电场阴极和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绝缘机构设置在电场流道外、即电场流道外,以防止或减少气体中的灰尘等聚集在绝缘机构上,导致绝缘机构击穿或导电。

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。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电场阳极和电场阴极分别与电源的两个电极电性连接。加载在电场阳极和电场阴极上的电压需选择适当的电压等级,具体选择何种电压等级取决于电场装置的体积、耐温、容尘率等。例如,电压从1kv至50kv;设计时首先考虑耐温条件,极间距与温度的参数:1MM<30度,工作面积大于0.1平方/千立方米/小时,电场长度大于单管内切圆的5倍,控制电场气流流速小于9米/秒。于本发明一实施例中电场阳极由中空阳极管构成、并呈蜂窝状。中空阳极管端口的形状可以为圆形或多边形。于本发明一实施例中 中空阳极管的管内切圆取值范围在5-400mm,对应电压在0.1-120kv之间,中空阳极管对应电流在0.1-30A之间;不同的内切圆对应不同的电晕电压,约为1KV/1MM。

本发明提供的电场装置可应用于气体除尘技术领域例如静电除尘装置,还可作为等离 子发生器(日光灯)、臭氧发生器等任何需要电场参与的装置。
下面以本发明提供的电场装置作为静电除尘装置为例进行实施说明,该静电除尘装置的结构与上述电场装置结构相同:
目前还采用电场装置对含尘气体所包含的颗粒进行除尘净化,其基本原理为,利用高压放电产生等离子,使颗粒带电,然后将带电的颗粒吸附至集尘电极上,实现电场除尘。但是现有静电除尘装置存在占用空间较大、耗能高、处理效率低等问题,
本发明提供的电场装置体积小、能耗低,可应用于气体除尘技术领域,某些实施例可有效脱除气体中颗粒物。
于本发明一实施例中电场装置可包括电场阴极和电场阳极,电场阴极与电场阳极之间形成电离电场。气体进入电离电场,气体中的氧气将被电离,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,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,电场阳极可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,电场阳极和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绝缘机构设置在电场流道外、即电场流道外,以防止或减少气体中的灰尘等聚集在绝缘机构上,导致绝缘机构击穿或导电。
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,防止水进入绝缘机构,造成绝缘机构短路、打火。另外,第一阳级部能够除去气体中相当一部分的灰尘,当气体通过绝缘机构时,相当一部分的灰尘已被消除,减少灰尘造成绝缘机构短路的可能性。于本发明一实施例中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电场阳极和电场阴极导通,从而使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。在气体流经电场流道过程中,第一阳极部和电场阴极先接触具有污染性的气体,绝缘机构后接触气体,达到先除尘后经过绝缘机构的目的,减少对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。
现有工业静电集尘电场由集尘极、放电极组成,电场各极由极板组成,平行排列为电场各极,电极对荷电粉尘有异性吸附力。但荷电为负极性就被正极吸附,荷电为正极性就被负极板吸附。但吸附后,荷电性就出现反转,趋于和极板同性,即正极板上粉尘会再次趋向负极、负极板上粉尘会趋向正极,这种运动和力是反复无休止产生,就形成电场耦合消耗。电场耦合消耗致使静电吸附粘附力弱的颗粒、液雾等出现效率下滑或失效。从而集尘效率低,且能耗较高。
本发明的发明人研究发现,现有电场装置去除效率差、能耗高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,将本发明提供的电场装置应用于静电除尘的情况下,本发明的电场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,现有电场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。
通常静电集尘电场的除尘效率通常较低,且能耗较高。为解决除尘效率低下等问题,现有技术中集尘电场往往选择多段串联,以提高整体集尘效率。此种多电场串联的方式又会导致集尘装置整体占用空间较大,能耗更高,且单电场的除尘效率实质上仍然很低。
于本发明一实施例中,所述电场装置包括与电场阳极和电场阴极之间不平行的辅助电场。
于本发明一实施例中,所述电场装置还包括辅助电场,所述电离电场包括流道,所述辅助电场与所述流道不垂直。
于本发明一实施例中,辅助电场给电场阳极和电场阴极之间带负电荷的氧离子流施加向后的力,使得电场阳极和电场阴极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电离电场的流道,带负电荷的氧离子在向电场阳极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 电场阳极作用下,能将更多的待处理物质收集起来,保证本发明提供的电场装置的除尘效率更高。
电场在应用中,往往会遇到因为氧气含量低而使粉尘荷电不充分,以及粉尘为容易导电物质,荷电后容易失去电子等现象。这些现象直接导致电场集尘失效。为避免这类事情发生,人们普遍认为除尘电场不能应用于氧气稀薄的尾气以及不能荷电成功的低电阻粉尘。比如氧气耗尽的汽车尾气中氧含量极低,最低只有0.3%,几乎无氧可电离,就无法产生氧离子,不能传递电子,粉尘就不能带电。另外对于水雾以及金属粉尘,由于容易带电,也容易失电,使用氧电离后荷电,很快就失效,电场也不能收集这类粉尘。另外,现有技术中静电集尘电场对粉尘等待处理物质的收集效率也较低。
于本发明一实施例中电场装置包括前置电极,该前置电极在电场装置入口与电场阳极和电场阴极形成的电离电场之间。当气体由电场装置入口流经前置电极时,气体中的颗粒物等将带电。
于本发明一实施例中前置电极上设有一个或多个通孔,气体通过所述前置电极上的通孔时,使气体中的颗粒物带电。本发明中当带颗粒物的气体通过前置电极上的通孔时,带颗粒物的气体穿过所述前置电极,提高带颗粒物的气体与前置电极的接触面积,增加带电效率。本发明中前置电极上的通孔为任何允许物质流过前置电极的孔。
于本发明一实施例中,在工作时,在带污染物的气体进入电场阳极和电场阴极形成的电离电场之前,且带颗粒物的气体通过前置电极时,前置电极使气体中的颗粒物带电。当带颗粒物的气体进入电离电场时,电场阳极给带电颗粒物施加吸引力,使所述带电颗粒物向电场阳极移动,直至带电颗粒物附着在电场阳极上。
于本发明一实施例中,所述前置电极将电子导入气体中的颗粒物,电子在位于前置电极和电场阳极之间进行传递,使更多气体中的颗粒物带电。
于本发明一实施例中,所述前置电极和电场阳极之间通过带电颗粒物传导电子、并形成电流。
于本发明一实施例中,所述前置电极通过与气体中的颗粒物接触的方式使气体中颗粒物带电。于本发明一实施例中前置电极通过与气体中的颗粒物接触的方式将电子转移到气体中的颗粒物上,并使气体中的颗粒物带电。
通常静电场耐受气体温度为200℃,超过200℃会引发电场击穿,特别是小型化高效电场,电场长度400毫米、通径300毫米蜂窝管束电场耐受温度为90℃。在90℃以下,这个电场集尘效率达到99%,但温度上升到120℃,电场会出现击穿、出现间歇性失效,引发集尘效率明显下降至50%以下。现有技术解决电场耐高温的方法通常为增大电场阳极和电场阴极的极间距、增大电场阳极和电场阴极的长度,防止电场击穿,而本发明提出减 小电场阳极和电场阴极的长度即缩短电场阳极和电场阴极的长度:电场阳极长度为1-9cm,电场阴极长度为1-9cm,解决电场发生单元及电场装置耐高温的问题,显然,现有技术给出相反的技术启示,本发明克服了技术偏见(增大电场阳极和电场阴极的极间距、增大电场阳极和电场阴极的长度),采用了人们由于技术偏见而舍弃的技术手段,从而解决了本发明要解决的技术问题。
进一步,本发明提出减小电场阳极和电场阴极的长度即缩短电场阳极和电场阴极的长度:电场阳极长度为1-9cm,电场阴极长度为1-9cm,当200℃烟尘进入后,由于停留时间短,活跃分子串联机会少,不能形成击穿电流,同时电场热变形引发极间短路变形量由于短而减小,更不容易引发击穿,电场装置耐受温度能达到500℃甚至大于500℃,且集尘效率高,高达50%,即本申请的电场发生单元和电场装置兼具高的耐受温度和高的集尘效率,与现有技术相比,本申请的技术效果产生“量”的变化,对于本领域技术人员来说,事先无法预测或推理出来,本申请取得了预料不到的技术效果,当发明产生了预料不到的技术效果时,一方面说明发明具有显著的进步,同时也反映出发明的技术方案是非显而易见的。
本发明一些实施例中,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%。

实施例12
本实施例提供的电场装置的结构示意图参见图6。如图6所示,所述电场装置包括电场阴极5081和电场阳极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。本实施例中电场阴极5081具有负电势,电场阳极5082和辅助电极5083均具有正电势。
同时,如图6所示,本实施例中辅助电极5083与电场阳极5082固接。在电场阳极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与电场阳极5082具有相同的正电势。
如图6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的长度方向可与电场阳极5082的长度方向相同。
如图6所示,本实施例中电场阳极5082呈管状,电场阴极5081呈棒状,电场阴极5081穿设在电场阳极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与电场阳极5082构成阳极管5084。阳极管5084的前端与电场阴极5081齐平,阳极管5084的后端向后超出了电场阴极5081的后端,该阳极管5084相比于电场阴极5081向后超出的部分为上述辅助电极5083。即本实施例中电场阳极5082和电场阴极5081的长度相同,电场阳极5082和电场阴极5081在前后方向上位置相对;辅助电极5083位于电场阳极5082和电场阴极5081的后方。这样,辅助电极5083与电场阴极5081之间形成辅助电场。
本实施例提供的电场装置可用于脱除空气中的颗粒物,上述辅助电场给电场阳极5082和电场阴极5081之间带负电荷的氧离子流施加向后的力。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6所示,本实施例中阳极管5084的后端与电场阴极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°。
本实施例中电场阳极5082、辅助电极5083、及电场阴极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。
本实施例中直流电源具体可为直流高压电源。上述电场阴极5081和电场阳极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,电场阴极5081和电场阳极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,形成电场阳极5082和电场阴极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%以上。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。

本实施例中辅助电极可与电场阴极固接。这样,在实现电场阴极与直流电源的阴极电性连接后,也实现了辅助电极与直流电源的阴极电性连接。同时,本实施例中辅助电极沿前后方向延伸。
本实施例中电场阳极呈管状,电场阴极呈棒状,电场阴极穿设在电场阳极中。同时本实施例中上述辅助电极也棒状,且辅助电极和电场阴极构成阴极棒。该阴极棒的前端向前超出电场阳极的前端,该阴极棒与电场阳极相比向前超出的部分为上述辅助电极。即本实施例中电场阳极和电场阴极的长度相同,电场阳极和电场阴极在前后方向上位置相对;辅助电极位于电场阳极和电场阴极的前方。这样,辅助电极与电场阳极之间形成辅助电场, 该辅助电场给电场阳极和电场阴极之间带负电荷的氧离子流施加向后的力,使得电场阳极和电场阴极间带负电荷的氧离子流具有向后的移动速度。
本实施例提供的电场装置可用于脱除空气中的颗粒物,当含有待处理物质的气体由前向后流入管状的电场阳极,带负电荷的氧离子在向电场阳极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,进而在电场阳极作用下,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。

如图7所示,本实施例中电场阴极5081和电场阳极5082在前后方向上位置相对,辅助电极5083位于电场阳极5082和电场阴极5081的后方。这样,辅助电极5083与电场阴极5081之间形成辅助电场,该辅助电场给电场阳极5082和电场阴极5081之间带负电荷的氧离子流施加向后的力。
本实施例提供的电场装置可用于用来脱除空气中的颗粒物,当含有待处理物质的气体由前向后流入电场阳极5082和电场阴极5081之间的电场,带负电荷的氧离子在向电场阳极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15
本实施例中电场装置的结构示意图参见图8。如图8所示,辅助电极5083沿左右方向延伸。本实施例中辅助电极5083的长度方向与电场阳极5082和电场阴极5081的长度方向不同。且辅助电极5083具体可与电场阴极5081相垂直。
本实施例中电场阴极5081和电场阳极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。本实施例中电场阴极5081和辅助电极5083均具有负电势,电场阳极5082具有正电势。
如图8所示,本实施例中电场阴极5081和电场阳极5082在前后方向上位置相对,辅助电极5083位于电场阳极5082和电场阴极5081的前方。这样,辅助电极5083与电场阳极5082之间形成辅助电场,该辅助电场给电场阳极5082和电场阴极5081之间带负电荷的氧离子流施加向后的力,使得电场阳极5082和电场阴极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电场阳极5082和电场阴极5081之间的电场,带负电荷的氧离子在向电场阳极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16
本实施例中电场装置的结构示意图参见图9。如图9所示,该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%,电场装置还包括电场阴极3081和电场阳极3082,电场流道3087位于电场阴极3081和电场阳极3082之间。
本实施例提供的电场装置可用于脱除空气中的颗粒物,含颗粒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将电子传导给部分颗粒物,部分颗粒物带电,当颗粒物由流道3086进入电场流道3087后,电场阳极3082给已带电的颗粒物施加吸引力,带电的颗粒物向电场阳极3082移动,直至该部分带电颗粒物附着在电场阳极3082上,同时,电场流道3087中电场阴极3081和电场阳极3082之间形成电离电场,该电离电场将使另一部分未带电的颗粒物带电,这样另一部分颗粒物在带电后同样会受到电场阳极3082施加的吸引力,并最终附着在电场阳极3082,从而利用上述电场装置使颗粒物带电效率更高,带电更充分,进而保证电场阳极3082能收集更多的颗粒物,并保证本发明电场装置对气体中颗粒物的收集效率更高。
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9所示,本实施例中前置电极3083和电场阴极3081均与直流电源的阴极电性连 接,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和电场阴极3081均具有负电势,电场阳极3082具有正电势。
如图9所示,本实施例中前置电极3083具体可呈网状,即设有若干通孔。这样,当气体流经流道3086时,利用前置电极3083设有通孔的结构特点,便于气体及颗粒物流过前置电极3083,并使气体中颗粒物与前置电极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颗粒物,并使颗粒物的带电效率更高。
如图9所示,本实施例中电场阳极3082呈管状,电场阴极3081呈棒状,电场阴极3081穿设在电场阳极3082中。本实施例中电场阳极3082和电场阴极3081呈非对称结构。当气体流入电场阴极3081和电场阳极3082之间形成的电离电场将使颗粒物带电,且在电场阳极3082施加的吸引力作用下,将带电的颗粒物收集在电场阳极3082的内壁上。
另外,如图9所示,本实施例中电场阳极3082和电场阴极3081均沿前后方向延伸,电场阳极3082的前端沿前后方向上位于电场阴极3081的前端的前方。且如图9所示,电场阳极3082的后端沿前后方向上位于电场阴极3081的后端的后方。本实施例中电场阳极3082沿前后方向上的长度更长,使得位于电场阳极3082内壁上的吸附面面积更大,从而对带有负电势的颗粒物的吸引力更大,并能收集更多的颗粒物。
如图9所示,本实施例中电场阴极3081和电场阳极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颗粒物,并使得本电场装置对颗粒物的收集能力更强,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和电场阳极3082之间通入直流高压,形成导电回路;电场阴极3081和电场阳极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。当容易带电的粉尘等颗粒物经过前置电极3083时,前置电极3083直接将电子给颗粒物,颗粒物带电,随后被异极的电场阳极3082吸附;同时未带电的颗粒物经过电场阴极3081和电场阳极3082形成的电离区,电离区形成的电离氧会把电子荷电给颗粒物,这样颗粒物继续带电,并被异极的电场阳极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,可利用电场阴极3081和电场阳极3082之间形成的电离放电电晕电场,电离氧,来使气体中的颗粒物荷电,再利用电场阳极3082收集颗粒物;而在气体中氧气含量过低、或无氧状态、或颗粒物为导电尘雾等时,利用前置电极3083直接使气体中的颗粒物上电,让气体中的颗粒物充分带电后被电场阳极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低的环境中,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。
