Description

高速离子风自吸式低温等离子体空气净化设备 技术领域
本实用新型涉及低温等离子体空气净化的技术领域，尤其涉及一种高速离子风自吸式低温等离子体空气净化设备。
背景技术
由于室内空间有限而且当前部分城市室外的空气质量不高，室内环境本身没有自然净化能力。室内装潢、空调器的使用以及人们的日常生活不断地向室内排放着有机挥发性气体、固体悬浮颗粒物和气溶胶等有害物质，造成室内空气污染进而危害人的身体健康。室内主要污染物包括粉尘、霉菌，TVOC等甲醛和苯系物，因此随着人们生活水平的提高，室内空气质量问题已经越来越受到人们的关注。
改善室内空气质量的主要方法有：(1)空气过滤方法，由风机、初效、中效、高效(亚高效)过滤器等组成，滤料主要是玻璃纤维、合成纤维、石棉纤维以及由这些纤维制成的滤纸或滤布和有吸附效果的如活性炭等材料，以便对空气中的尘灰及异味进行过滤以净化空气，但是这些多孔滤材会增加空气流动的阻力，而且随着使用时间的延长，其过滤的效果会下降，如不及时进行更换，反而会加重空气的污染，甚至产生二次污染；(2)静电除尘法，通过对循环空气中的尘灰带电，然后利用集尘装置捕集带电的尘灰，达到净化空气的目的，但是这种方法不能够杀灭空气中的细菌以及TVOC等有毒异味气体，而且设置和清洗集成板不便；(3)紫外线杀菌方法，利用紫外线杀灭空气中的病菌，但对空气中的尘灰无能为力，不能够净化空气。(4)低温等离子体净化方法，通过低温等离子体发生器发生的强电离场和气体放电，使空气中的水分子和气体分子电离，经过一系列复杂的激发、离解和电离过程，产生化学性质极其活泼的活性基团，与空气中的污染物发生一系列复杂的氧化还原反应，其中挥发性有机物分子被分解，由此实现空气净化的目的，这 些自由基对于微生物也具有强的灭活作用，在消除有机污染的同时实现了灭菌的目的。同时通过带电粒子对尘灰的非弹性碰撞使其带电并加重被集中收集净化。
等离子体空气净化器主要由高压电源和等离子电离场两大部分组成，目前等离子电离场部分主要有板对板型、线对板型、针对板型及线对桶型等多种结构形式。授权公告号为CN 2688390Y的实用新型专利公开了一种等离子消烟除尘装置，其净化部分由不锈钢管、金属钼丝和正、负电极板构成。其存在的技术问题是：空气净化速度慢，净化效果不理想，需要辅助风机使用。

为了达到上述目的，本实用新型一种高速离子风自吸式低温等离子体空气净化设备，包括释放直流高压电的电源模块、起到支架作用的外壳、产生强电离场的发射极以及吸附各种粒子的集尘极；所述发射极包括一至多根针状导体，所述集尘极上开设有与每根针状导体相适配的圆孔，所述发射极上的一至多根针状导体从电源模块中引出并指向集尘极的圆孔，所述电源模块可拆卸固定在外壳上或与外壳分离布置，所述发射极与集尘极围合作用形成等离子体区域。
其中，所述针状导体由柱状本体和尖头构成，所述柱状本体和尖头为一体成型结构，柱状本体的一端与电源高压电路相连，且另一端为尖头，每个针状导体的尖头均指向集尘极上相对应的圆孔圆心。
其中，所述集尘极与电源模块通过电源模块上引出的导线实现电连接，集尘极上的圆孔以环形阵列方式或者矩形阵列方式排布，所述圆孔的孔径为5-50毫米。
其中，该空气净化设备还包括防止灰尘集结的导气锥，所述导气锥为弧形锥体结构，所述导气锥容置在外壳内，且所述导气锥的尖端部位对准外壳的空气入口。
其中，该空气净化设备还包括外盖，所述外盖设置在外壳的空气入口处， 所述外壳上开设有多个与固定支脚相适配的凹槽位，所述外盖与外壳之间进行可拆卸固定连接。
本实用新型的有益效果是：
与现有技术相比，本实用新型的高速离子风自吸式低温等离子体空气净化设备，电源模块产生高压，连接到发射极，发射极产生的强电离场区域会产生指向集尘极的高速电子，以及在针尖周围产生等离子体区域，高速移动的电子及带电粒子会非弹性碰撞附着在空气中污染物分子和空气中其他颗粒上一起向集尘极移动，而形成风；在灰尘通过发射极产生的等离子体区域的时候，会通过非弹性碰撞吸附上高速移动的电子，因静电力作用，带负电的颗粒就会向集尘极运动而附着在集尘极上，完成空气中颗粒物的净化；TVOC和甲醛，菌类分子，再通过等离子区域的时候，高能电子和等离子区域产生的氧化基团会直接氧化和破坏其分子，使其氧化分解，同时高速高能带电粒子对病毒及菌类细胞具有穿透类破坏效果亦可将其杀灭。
本实用新型结构简单，体积小巧，净化速度快，空气净化效果好，可以不用辅助风机使用；接收极的多孔状金属结构，增大了空气净化接触面积，使得接收极具有较强的吸附能力；采用低温等离子体技术，耗电量低，节能和静音效果显著。
