[0038] 负极片 5和正极片 6的壁厚为 0.1mm~2mm。 本发明中， 负极片 5和正极片 6均采 用壁厚 0.15mm的铝合金薄片， 大大降低了成本， 减轻了重量， 却丝毫不减弱净 化能力， 反而比传统静电集尘装置的除尘效果提高 5%-10<¾以上。
[0039] 在负极片 5和正极片 6的外表面设有氧化钛涂层。 在高压场强的作用下， 可催化
、 分解附着于物体表面的甲醛和 TVOC等有机气体， 起到杀灭微生物、 清除细菌
、 消除臭味及清洁空气的效果。
[0040] 两个相邻的负极片 5和正极片 6的间距为 2.0mm~5mm。 这与传统的静电集尘装 置电极片间距 6mm~8mm相比可以产生相同的电场强度， 同吋可以将施加到本发 明上的电压降低到原来的 50%~60<¾， 解决了工艺复杂的问题， 同吋大大减小了 负极片 5和正极片 6之间的放电电流， 既而大大减弱了放电噪声， 节省了能源， 具有更高的安全性。
[0041] 负极片 5和正极片 6的弧度的弦长与弦高之比为 3~40。 本实施例负极片 5和正极 片 6的弦长为 25mm， 弦高为 1.6mm。 如果弦长与弦高之比为小于 3则风压损失太 大， 不能满足做集尘装置的使用要求。 如果弦长与弦高之比大于 40则不能满足 集尘装置的使用机械强度要求。 在相同宽度的负极片和正极片的条件下， 本实 施例的集尘装置与现有技术相比具有无臭氧、 无放电噪声、 集尘效率高、 容易 清洁等特点。
[0042] 以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发明的 精神和原则之内所作的任何修改、 等同替换和改进等， 均应包含在本发明的保 护范围之内。 本发明的实施方式
