摘要:目前,由吸附性材料制成的防雾霾纱窗具有不易更换、一次使用性的缺点,因而难以满足在长时间内的高质量防雾霾需求。由此本文设计了一种基于电路控制的防雾霾窗,它能够阻止雾霾中的有害颗粒物质进入室内,又不妨碍使新鲜空气进入室内,提高室内的空气质量。该防雾霾窗结构的设计简单方便,易于实现。它通过电路控制模块在三层窗户网之间制造足够强的外电场,使雾霾粒子受力,作用于粒子的运动,从而达到阻隔雾霾粒子的目的。此外,在防雾霾窗的设计上增加了防雾霾窗的自我保护能力,使用户的安全得到保证。

Abstract: Nowadays, the smog-proof screen made of an adsorbent material has the characteristics of being disposable and difficult to replace, and it is difficult to meet the long-term high-quality anti-smog requirement. Therefore, a circuit-controlled defogging window is designed, which can prevent harmful particles in the smog from entering the room without hindering the entry of fresh air into the room and improving the indoor air quality. The design of the anti-smog window structure is simple and convenient, and is easy to implement. It uses the circuit control module to create a strong external electric field between the three-layer window nets, so that the smog particles are forced to act on the particles to achieve the purpose of blocking the smog particles. In addition, the self-protection ability of the anti-smog window is added to the design of the anti-smog window, which ensures the safety of the user.

Key words: circuit control; anti-fog window; air quality; electric field; self-protection;

1 研究背景和意義

如今,中国不少地区将雾并入霾一起作为灾害性天气现象进行预警预报,统称为“雾霾天气”。雾霾,是雾和霾的组合词。一般情况下,相对湿度介于80%-90%时,由大气混浊视野模糊导致能见度恶化的现象是霾和雾的混合物共同造成的,但其主要成分是霾。霾粒子的分布比较均匀,而且雾霾粒子的尺度比较小,从0.001微米到10微米不等,平均直径大约在1-2微米左右,肉眼看不到空中飘浮的颗粒物[1]。所以无处不在的,带着有害物质的雾霾空气会轻松进入室内,降低室内空气质量,对人体产生危害。比如雾霾中混有大量这些有毒有害的小颗粒,会随着空气进入人的呼吸道和肺部,对人的身体健康带来威胁,轻者会引进气管炎、肺炎等疾病,重者会导致更加严重的疾病。……
