Description

氧离子发生管 技术领域
本发明涉及一种空气电离技术， 尤其涉及一种在净化空气装置中使用的氧 离子发生技术。 背景技术
现代文明的发展使在城市中生活的人们， 对清新自然的空气的质量的需求 越来越高。在都市楼宇中， 目前是通过改善中央空调的功能来达到集尘、灭菌、 除味等目的， 模仿大自然空气净化的过程。 在大自然生态环境中的自净化功能 是依靠空气中的正负离子 （主要是氧离子） 作用于在空气中的浮尘 （可吸入颗 粒） 、 浮游菌及有机挥发物 （TV0C) 等， 将其带上双极异号电位， 促使其分解 或变异最后降落地面 （大地为零电位） ， 这实际上是一种氧化过程。 在人工空 气净化的领域中常常也是采用空气电离（人工电暈）的办法来达到集尘、灭菌、 除味等目的。
在国内外在楼宇空气净化领域中的空气电离技术通常采用如下方式实现-
1、 采用尖端放电原理使靠近尖端的空气电离， 其正极一般用比较锐利的 针尖（不锈钢针或经特殊加工的钨针）， 负极形式有采用平板、多边孔及圆孔。 由于其针尖端的在高压下氧化的缘故很快就钝化， 表面曲率的减小使电子脱离 金属表面的势垒增大， 要维持其持续的放电只能加高电压， 过高的电压在针尖 端会产生较多的臭氧与形成氮氧化合物， 这对人体的健康与设备的安全都有 害， 因此该方式现在在楼宇空气净化领域中很少有使用；
2、采用导电纤维束端头以虚拟负极的方式放电， 其是前一种方式的变形， 一般用于负离子发生器；
3、 采用细圆金属线的大曲率表面对平板、 多边形柱孔及圆柱孔的内表面 进行放电， 这是从锅炉静电集尘原理微缩演变而成的， 尽管在线电场附近的离 子浓度较大， 因受电场负极的约束机制， 其很难向室内空气中注入大量的正负 离子；
4、 采用细圆金属线的大曲率表面对与其同心的网状圆弧面进行放电， 当 气流从网状圆弧面流经其与细圆金属线的等势场后携带正负离子进入室内空 间， 由于其分别产生的正负离子较难形成寿命较长的氧簇， 因此限制了其使用 的范围；
5、 采用沿面放电带正压引出装置的电离管是国外在楼宇空气净化系统中 的主流产品， 其釆用交流高压的方式能够在一个电场上交替产生正负离子， 其 主要的放电机制是金属薄片上冲制的密集圆孔产生边缘放电， 外置的钢丝网套 加载一定的电压作为离子引出机构， 沿径向空间作发散状态， 该系统采用高频 交流高压的供电方式一般工作在 AC 2500V— 2750V左右， 频率在 28— 32KHz范 围中， 距电离管 5cm处， 其交替产生的正负离子的浓度在 2-3X107CM3。 对比 于国内的一些装置， 其在工作电压方面已经远远低于上述结构 （1一 4) 的电场 系统， 能在同一电场上交替产生正负离子， 并扩散到空间中能够比较容易形成 氧簇， 对于楼宇净化有非常积极的意义。 但是该设备不能在较短的时间产生大 量正负离子， 对于在室内空气质量较差的楼宇环境不能较快达到空气净化的效 果。 如果提高电压， 调制接近 3000V时， 又将会产生较多的臭氧。
由此可见， 上述的气体电离装置均不能同时满足如下要求：
1. 在一个装置 （或器件） 中能够快速产生足够的正负氧离子；
2. 该装置（或器件）在气体电离的过程中尽可能处于较低的电压状况下， 以产生的氮氧化合物和臭氧量为最低；
3. 该装置 （或器件） 在各种空气环境中能正常产生足够的正负氧离子。 发明内容
本发明的目的是提供一种新型的氧离子发生管， 可以使用较低交流电压在 短时间内快速产生足够的正负氧离子， 达到净化空气的目的。
本发明的再一目的是提供一种新型的氧离子发生管， 可以在各种空气环境 中能正常产生足够的正负氧离子， 达到净化空气的目的。
一种氧离子发生管，包括一中空绝缘管，一对放电线圈以及一个感应线圈， 其特征在于， 所述放电线圈由两根平行等距地盘绕在所述中空绝缘管外壁的金 属线构成， 所述感应线圈由一根沿所述中空绝缘管内壁盘绕的金属线构成， 所 述感应线圈与一根放电线圈并联接交流电源负极， 所述另一根放电线圈接交流 电源正极。
本发明的氧离子发生管， 还包括一放置在中空绝缘管内的加热元件。
较佳地， 所述中空绝缘管由工业玻璃或陶瓷材料制成， 在管的外壁上平行 等距设有两条用于分别放置两根放电线圈的金属线的螺旋槽。
较佳地， 所述金属线可为金属裸线。
较佳地， 所述金属线可为窄金属裸带。
较佳地， 所述加热元件置于盘绕在中空绝缘管内壁的感应线圈内侧。
较佳地， 所述加热元件与一湿度感应开关接后接入电源。
较佳地， 发热元件可以是电阻丝。 较佳地， 发热元件也可以是发热陶瓷。
较佳地， 所述湿度感应开关按照对空气湿度的要求设置好启动和关闭的条 件， 控制电加热元件的加电的开启和关闭。
本发明所述的氧离子发生管的工作原理是， 在氧离子发生管接入交流高压 电源后， 在中空绝缘管外壁上平行等距盘绕的一对放电线圈之间， 同时与放置 在中空绝缘管内壁的感应线圈之间均形成电压差， 在一定的电压作用下， 中空 绝缘管外壁上的一对放电线圈金属线两极 （线） 间的气体被电离， 在两极间被 电离气体放电时在放电线圈间形成磁感应电流， 该磁感应电流将切割盘绕在中 空绝缘管内壁的感应线圈， 在感应线圈的中产生感应电流， 在感应电流流至接 地极的过程中， 其将形成一个交变磁场， 当盘绕在中空绝缘管内壁的感应线圈 处于较为稀疏的状态下， 中空绝缘管内感应线圈在径向的磁力线不被抵消， 反 而能影响在放电线圈的正负极中运动的正负离子改变在磁场中的运行方向， 使 其呈发散状， 向空间发散， 较快达到增加空气中带电氧离子的浓度。 正负氧离 子扩散到空间里与小颗粒尘埃、 气溶胶及病菌等有害物质结合， 使其形成较大 颗粒的双极分子团， 迅速沉降到地， 室内空气品质得到优化。
本发明提供的氧离子发生管与现有装置相比， 由于利用放电线圈在电离过 程中产生的磁感应电流感应另一感应线圈， 使感应线圈其产生的另一交变磁场 反作用于在放电线圈的正负极中运行的正负离子， 改变其正负带电离子在磁场 中的运行方向， 使其呈发散状， 所以能较快增加空气中带电离子的浓度， 达到 空气净化的目的。
通常， 在空气湿度较大时， 氧离子管的工作效率比较低。 本发明的氧离子 发生管， 在中空绝缘管内设置一加热元件， 在空气湿度较大时开启中空绝缘管 内的加热元件， 可以为中空绝缘管内部和外壁周围降低空气湿度， 保证氧离子 发生管正常工作。
本发明提供的氧离子发生管的工作原理， 将结合附图作进一步阐述。 附图简述

图 2是图 1中 K点的放大示意图，表示本发明的氧离子发生管工作时交变 磁场的示意图。

参看图 1， 本发明的氧离子发生管， 中空绝缘管 1由工业玻璃或陶瓷材料 制成， 在中空绝缘管 1的外壁上平行等距设有两条螺旋槽， 放电线圈 2和放电 线圈 3平行等距地盘绕在中空绝缘管 1外壁上的螺旋槽中， 裸距导程为 2t外； 感应线圈 4沿中空绝缘管 1的内壁盘绕； 放电线圈 2接交流电源 5的正极 （火 线） , 放电线圈 3与感应线圈 4的一端并联后接交流电源 5的负极 （地线） 。
本实施例中， 放电线圈 2和 3， 以及感应线圈 4的是采用金属线， 也可以 采用窄金属裸带。
在中空绝缘管 1的内部中心位置设置一加热元件 6， 加热元件 6置于盘绕 在中空绝缘管内壁的感应线圈 4的内侧， 加热元件 6与一湿度感应开关 7连接 后接入电源 8。
加热元件 6可以是电阻丝， 也可以是热电陶瓷。
湿度感应开关 7可以按照对空气湿度的要求设置好启动和关闭的条件， 当 空气中湿度较大时， 湿度感应开关 7自动接通， 加热元件 6被接入电源 8开始 加热， 保证氧离子管的在湿度较大的空气中正常工作。
本发明的氧离子发生管的工作原理如图 2所示， 当放电线圈 2接入交流高 压电源正极， 放电线圈 3和感应线圈 4接交流高压电源负极， 放电线圈 2上的 正电压与放电线圈 3之间形成电压差， 在一定的电压下促使在放电线圈 2和放 电线圈 3之间的气体电离， 在放电线圈 2和放电线圈 3形成的两极 （线） 间也 就形成了磁感应电流， 如图 2中所示 I为电流 （离子运动） 方向， 磁感应电流 将正负离子从正极推向负极。 气体电离产生的磁感应电流产生交变的磁场， 该 交变磁场还将感应放置在中空绝缘管内的感应线圈 4, 在感应线圈 4中产生的 感应电流在流至负极的过程中， 将形成另一个交变磁场， 当感应线圈 4处于较 为稀疏的状态下 （t A = l/2t ) ， 感应线圈 4在径向的磁力线不会被抵消， 而 能影响在中空绝缘管外的放电线圈 2和放电线圈 3的正负极间运行的正负离 子， 会改变带电离子在磁场中的运行方向， 如图 2中 B为垂直于纸面的磁场分 力， 当空间存在另一磁场时， 离子的运动不是简单的在正负极中近似直线的到 达与其极性相反的一极， 离子本身作为带电粒子， 在磁场中带电粒子的运动如 切割磁力线运动时， 其会受到与运动方向 （电流方向） 和与磁力线法向夹角垂 直的力， 因此， 此时的离子不再作直线运动， 而是作圆周运动。 图 2中的 F方 向为离子受到磁场力作用下的运行轨迹， 其呈发散状。
以下是由于磁场引起的扩散过程的简单推导。 如图 3所示， 假定磁场垂直纸面向外^ 那么在垂直方向从左面穿过面积 元 dA的离子是从拉摩半径 II的下面一个圆上某处碰撞而来的； 从右面穿过面 积元 dA的粒子则是从上面一个圆上碰撞而来的。 如果沿任一路程从 dA导碰撞 点的距离为 S， 则从左面来的通量为 -

从右面来的通量为：

其中 S上和 S下分别是下圆和上圆的轨道长度。
假定 n只在 X方向有变化， 则有泰勒级数展开 n(x)，并保留到第二级， 可 得：

对于同在室温及平均自由程， 由于离子质量远比电子质量大的多， 故离子 的扩散系数远比电子横越磁场的扩散系数大， 即0 〉 1)6， 这是因为横越磁场的 扩散是每次碰撞后粒子拉摩圆中心位置的无规改变的结果， 这个偏移量的数量 级与拉摩半径相同， 由于离子的拉摩半径大， 所以它扩散得快。
通过以上阐述， 本发明提供的氧离子发生管与现有装置相比， 由于利用电 离过程中产生的磁感应电流感应另一感应线圈， 使其产生的另一交变磁场， 反 作用于在正负极中运行的正负离子， 改变其带电离子在磁场中的运行方向， 使 其呈发散状， 向空间发散， 所以， 本发明能较快达到增加空气中带电离子的浓 度， 达到空气净化的目的。
如下表（摘自 15031.519P15表 1.6)所示， 从分子结构上看， 由于氧分子 与其它气体分子相比具有较多的电子层数， 且其最外层的二个电子为二个原子 核共有并且不满足最外层的电子数， 因此其最容易被电离， 成为氧离子 O2+或 o2-; 因此必须考虑离子发生器对被电离气体只能施以较低的激发能量。

本发明的氧离子发生管在设计中以较低的电压运行， 因为电压比较低， 所 以氧分子在电场里不能获得更高的能量而导致分子离解， 因此单原子氧产生的 几率较低， 所以形成臭氧、 一氧化氮及氮氧化合物就比较少。
在实际运行测试中， 本发明的氧离子发生管在加电压为 AC1500— 2000V区 间时， 其臭氧的对本底增量小于 0. 015ppm， 这说明工作在较低的能态区间， 离 子管激励气体粒子产生电离以氧气分子为主。
在现场试验中与国际上用于室内空气净化的电离管相比较，管直径为其 50
% , 工作电压为其 65%时， 距电离管外表面同等距离下的测得的离子浓度要高
5- 10倍。
图 4是本发明的氧离子发生管在现场实测氧离子产生的时间曲线图。 从图 4中可以看出， 开机后 5分钟， 室内氧离子迅速提高。 由此可见， 本发明的氧 离子发生管的特殊结构的可以在较短时间内增加空气中带电离子的浓度。
图 5是本发明的氧离子发生管在现场实测对室内可吸入颗粒物净化的时间 曲线图。 从图 5中可以看出， 在 5分钟内就可以将室内空气净化达到标准。
图 6是本发明的氧离子发生管在现场实测降氨时间曲线图， 在干式动物饲 养房内饲养了 126只豚鼠， 关闭送排风系统及门窗 24小时， 由图 6中可以看 出， 在 30分钟内就可以将氨净化达到标准线以下。
综上所述， 本文所提出的氧离子管能够在使用较低电压下， 在较短时间内 产生大量氧离子， 达到净化室内空气及的效果。 同时也不受空气湿度的影响， 在各种空气环境中能正常产生足够的正负氧离子， 达到净化空气的目的。
