一种高效空气杀菌消毒的装置 技术领域
本发明涉及一种空气杀菌消毒装置，尤其涉及一种改进其净化结构 提高杀菌效率的空气杀菌消毒装置。 背景技术
随着我国 "非典" 的发生， 人们对空气净化和杀菌消毒的要求愈来 愈高，然而，现有技术中的空气净化技术实际上一直是无法令人满意的， 即使是现在较为发达国家的空气杀菌消毒装置， 其持久、 高效的维持空 气杀菌效率都是难以 4故到的。 目前的空调系统中， 尤其是中央空调， 一 旦使用一段时间， 经检测就会发现， 病菌会在风管内沉积和生长并成为 新的污染源。
现有技术中的空气杀菌消毒装置， 不少场所使用的是高压静电除尘 除菌空气消毒器原理， 如图 1所示的， 其在一定的空气流动通道内， 先 后设置有一电暈放电层 110， 和一高压静电集尘层 120, 所述电晕放电 层 110中间设置有多条放电丝， 当将电流接通后， 该层内产生电晕， 使 经过该层的尘埃等颗粒物带电，其作用就是使经过的颗粒变成带电的离 子。 所述高压静电集尘层 120也是由多层构成， 层与层之间有空气通过 的缝隙， 并有高压静电加在该高压静电集尘层 120上， 这样在经过前一 层后形成的带电离子， 即尘埃颗粒等经过本层时就会被吸附到该高压静 电集尘层 120上， 从而达到集尘除尘、 除菌、 空气杀菌消毒的效果。 同 时，在所述电晕放电层 110进行离子化时会产生一些射线和微量活性氧， 以及在所述高压静电集尘层 120吸附带电颗粒时产生的电流可以用来对 尘埃颗粒中的病菌进行杀灭， 但其杀灭效率是不高的， 试验发现， 现有 技术的高压静电集尘层上积聚了大量的细菌、 病毒颗粒， 细菌、 病毒并 没有因为有高电压等因素存在而死亡， 二次开机时， 上述病菌和病毒颗 粒仍会从杀菌消毒装置中飞出， 因此， 现有技术中的空气杀菌消毒装置 主要的作用在于集尘而不是灭菌， 其本身也是潜在的污染源。 因此， 现有技术存有缺陷， 而有待于进行技术改进和发展。 发明内容
本发明的目的在于提供一种高效空气杀菌消毒的装置，通过增加紫 外光源， 进行对高压静电集尘层上积聚的颗粒进行集中照射杀灭病菌， 并对高压静电集尘层间的流动空气中的颗粒中的病菌进行杀灭， 能够高 效地进行空气杀菌消毒。
本发明的技术方案如下：
一种高效空气杀菌消毒的装置，其包括依次设置在空气流动通道内 的至少一层电暈放电层及至少一层高压静电集尘层，所述电晕放电层使 经过的颗粒带电， 所述高压静电集尘层用于吸附各带电颗粒， 所述装置 还包括至少一紫外光源， 设置在所述空气流动通道内， 其中， 所述紫外 光源靠近所述高压静电集尘层设置， 用于照射在所述高压静电集尘层 上。
所述的装置， 其中， 所述紫外光源设置在所述高压静电集尘层的下 游方向， 并集中照射在所述高压静电集尘层上。
所述的装置， 其中， 所述紫外光源设置在所述高压静电集尘层的上 游方向， 并集中照射在所述高压静电集尘层上。
所述的装置， 其中， 所述紫外光源还设置在所述高压静电集尘层的 上、 下游两侧， 并同时集中照射在所述高压静电集尘层上。
所述的装置， 其中， 所述电晕放电层、 高压静电集尘层以及所述紫 外光源组成一基本单元，所述装置在所述空气流动通道内依次设置有多 个基本单元。
所述的装置， 其中， 所述装置还设置有一有害气体吸附分解层在所 述各基本单元后的下游位置。
所述的装置， 其中， 所述装置还包括一风机， 用于增加所述空气流 动通道内的空气流动驱动力。
所述的装置， 其中， 所述装置还包括一屏蔽外壳， 将所述各基本单 元纳置在所述空气流动通道内， 防止有害射线的辐射泄漏。 所述的装置， 其中， 所述紫外光源与所述高压静电集尘层的距离为
0 ~ 3厘米。
本发明所提供的一种高效空气杀菌消毒的装置， 由于采用了紫外光 源， 利用紫外光源在所述高压静电集尘层上进行集中照射， 实现了快速 高效的空气杀菌消毒功能， 并能长时间地维持高效率的空气杀菌消毒。 附图说明
以下结合附图， 通过对本发明的较佳实施例的详细描述， 将使本发 明的技术方案及其有益效果显而易见。
附图中，
图 1是现有技术的空气杀菌消毒装置的原理示意图；
图 2为本发明的一种高效空气杀菌消毒的装置的较佳实施例的示意 图；
图 3 为本发明的一种高效空气杀菌消毒的另一较佳实施例的示意 图；
图 4为本发明的一种高效空气杀菌消毒的装置的再一较佳实施例的 示意图。 具体实施方式
下文， 将详细描述本发明。
本发明的一种高效空气杀菌消毒的装置， 如图 2和图 3所示的， 其 基本原理是相同的， 都是在一电晕放电层 210和一高压静电集尘层 220 后， 在所述高压静电集尘层 220附近再设置有一紫外光源 230， 该紫外 光源 230用于照射杀灭病菌，较好的是在所述高压静电集尘层 220下游 方向、 上游方向或在上下游方向设置该紫外光源 230, 上下游方向的设 置如图 4所示的， 这样， 在所述高压静电集尘层 220集尘的过程中， 将 病菌也集中在该高压静电集尘层上了，然后用该紫外光源 230进行集中 照射即可， 因此可提高杀灭效率。 所述电暈放电层 210、 高压静电集尘 层 O以及紫外光源 230的设置方式可以有多种，但应设置在一空气流 动通道内； 所述紫外光源与所述高压静电集尘层的距离可以在 0 ~ 3厘 米之间， 即可以非常贴近所述高压静电集尘层， 也可以稍离， 但不能太 远。 图中箭头所示， 为空气的流动方向。
在该空气流动通道内， 利用紫外光源 230进行高效长久杀菌， 并且 依较好的方式，将该紫外光源 230设置在所述高压静电集尘层 220的下 游方向、 上游方向或上下游方向， 这样就更能对集中在该高压静电集尘 层 220上的病菌进行杀灭，这种主动灭菌的方式显然比现有技术中更能 抑制病菌在该高压静电集尘层 220上的聚集和滋生， 因此能更有效的长 久保持经过的空气中的细菌病毒被杀灭。
本发明的所述高效空气杀菌消毒的装置，其可以将所述电晕放电层 210、 高压静电集尘层 220以及所述紫外光源 230依次放置形成一基本 单元， 进行模块化设置； 为增加杀菌效率， 可以设置多层基本单元， 如 图 3所示的， 这可以设置在风管中并且要求杀菌效果更高的情况下， 因 其空间较大。如图 2或图 3所示的，本发明的高效空气杀菌消毒的装置， 可以设置在一较长的空间内， 如进风风管内或出风风管内， 本发明的高 效空气杀菌消毒的装置， 在被模块化设置后， 可以做成较薄的模块体， 这样的应用范围将更宽， 例如， 可用于空调设备的进、 出风口， 壁挂式 或窗口式空气杀菌消毒装置等等，该杀菌消毒装置相比现有技术具有明 显且持久的杀菌功能。 图中所述电晕放电层 210、 所述高压静电集尘层 220为双区式结构， 但在外观上可以合二为一， 成为单区式结构。
本发明的高效空气杀菌消毒的装置，在所述基本单元的下游位置还 可以设置一有害气体吸附分解层 240, 该有害气体吸附分解层 240可以 由活性炭构成， 用于对一定量的有害气体进行吸附和分解。 另外， 如果 该空气流动通道内的空气流动不畅时， 就需要增加一风扇 250， 进行气 压驱动， 使其中的空气能按图示箭头方向流动。
由于本发明的高效空气杀菌消毒的装置中有所述电暈放电层 210、 所述高压静电集尘层 220和所述紫外光源 230， 因此， 其空气流动通道 或基本单元的外壳应采用一定的屏蔽壳， 以防止电磁波、射线对人体的 伤害。 所有本领域普通技术人员应该理解的是， 所述紫外光源可以是灯 管或灯泡， 其所发出的紫外线一般为 uv- (：。
本发明的所述高效空气杀菌消毒的装置，对高压静电集尘层间流动 空气中没有捕获到集尘层上的带菌颗粒， 由于电场力的作用， 使颗粒的 运行速度减' ft, 由于增加了紫外光源， 可以对颗粒中的细菌、 病毒受紫 外线照射时间延长， 从而可以对颗粒物中的病菌能更好的杀灭， 如此通 过电晕放电层、 高压静电集尘层以及紫外光源后， 病菌杀灭效率提高了 数倍至数十倍， 能够在数秒至数十秒内将集尘层的病菌杀灭， 克服了只 集尘不灭菌的缺陷， 只要能捕获到集尘层上的颗粒即可完全杀灭， 从而 在第二次开机时飞出的带菌颗粒大大减少，解决了现有技术的杀菌消毒 装置本身成为污染源的问题。
以下是在空气环境中，采用图 1所示现有技术和图 2所示本发明的 试验对比结果：
一、 开机 30 分钟后分别对现有技术和本发明集尘层的带菌颗粒 数目检测结果比较表
Figure imgf000007_0001
检测条件及计数方法： 温度 20°C- 25。C,相对湿度 50%- 60%, 高压静电集尘层上 电压为 8000V- 10000V, 分别从高压静电集尘层采样， 放入采样亚中， 然后， 在恒温 箱中 37 °C培养 48h, 计数。
由此可以看出， 现有技术中普遍认为由电晕放电层和高压静电集尘 层组成的空气杀菌消毒装置能够杀菌的认识是错误的，本发明杀灭的效 率明显提高。
二、 第二次开机（同时， 同风速， 同采样亚等条件）， 对飞出的带菌 颗粒检测结果比较表
Figure imgf000007_0002
检测条件及计数方法： 风速 2m/s , 温度 20°C- 25 °C ,相对湿度 50%°C- 60%, 高压 静电集尘层上电压为 8000V-10000V，在出风口等距离 10cm的位置，用同样大小的采 样 J 分别采样，釆样 5min, 然后在恒温箱中 37°C培养 48h,计数。 由此可以看出， 从现有技术的杀菌消毒装置中飞出的带菌颗粒数目 比同样试验条件下的空气中的带菌颗粒数目还要多， 因此证明它是一个 潜在的污染源， 本发明则很好地解决了这个问题。
室内空气循环测试结果， 本发明的杀菌效率〉 99. 9999°/»，此为空气杀 菌消毒装置的国家标准。
此外， 本发明的特点在于结构筒单， 实用， 维护方便， 维护费用低。 应当指出的是，本发明的高效空气杀菌消毒的装置上述具体说明仅仅是 具体的实施例， 对本领域'普通技术人员来说， 可以根据本发明的技术方 案及其构思进行其他等同改变或替换， 而所有这些改变或替换都应属于 本发明所附权利要求的保护范围。
