本发明涉及一种新型光催化空气消毒机,属于空气消毒设备技术领域。
背景技术
现有的空气消毒机主要包括臭氧空气消毒机、紫外线空气消毒机、等离子空气消毒机和光触媒空气消毒机;其中,臭氧空气消毒机是通过高能离子把氧气离解成氧原子,氧原子再和氧分子结合形成臭氧;臭氧能够将浮游于空气中的霉菌孢子、细菌及其他引起异味的细菌氧化分解,完全消除霉菌,且由于臭氧属于气体,对于杀除细菌无孔不入,食品行业应用比较广泛;但臭氧的气味强烈刺激人的呼吸道,造成咽喉肿痛、胸闷咳嗽,易引发支气管炎和肺气肿,因此需要定时用量度臭氧的仪表来监测浓度;紫外线空气消毒机是通过紫外线对细菌、病毒等微生物的照射,以破坏其机体内DNA(去氧核糖核酸)的结构,使其立即死亡或丧失繁殖能力;其能耗低、运行费用低;自动化程度高;维护简便,具有无二次污染的特点;但由于紫外线能够穿透细胞使其死亡,因此用紫外线消毒时要注意不能直接照射到人的皮肤,尤其是人的眼睛;当空气中灰尘太多,灯管容易积污垢膜,需要定时清理,否则因抑制紫外线的透射,影响消毒效果;等离子空气消毒机可以同时产生正离子与负离子,在空气中进行正负电荷中和的瞬间产生巨大的能量释放,从而导致其周围细菌结构的改变或者能量的转换,从而致使细菌死亡,实现其杀菌的作用;其杀菌快速彻底,对空气中自然菌杀菌率30分钟达到100%,对大肠杆菌、金黄色葡萄球菌、白色念珠菌40分钟内达到99%以上;不需更换滤网,定时清洁即可;但此类空气消毒机的集成室表面若开始累积微粒时,滤净效果会快速的大幅降低,需要经常保养;集成板脏污时,会发出噼啪的响声,容易损坏;且此过滤方式会产生臭氧,对人体呼吸器官有刺激性;光触媒空气消毒机其光触媒在光的照射下,会产生类似光合作用的光催化反应,产生出氧化能力极强的自由氢氧基和活性氧,具有很强的光氧化还原功能,可氧化分解各种有机化合物和部分无机物,能破坏细菌的细胞膜和固化病毒的蛋白质,可杀灭细菌和分解有机污染物,把有机污染物分解成无污染的水(H2O)和二氧化碳(CO2);光触媒技术可除去空气中的细菌、病毒等,对部分挥发性有机化合物起到分解的作用;由于其环保、安全特点,目前被众多空气消毒机厂家选用;但其可能把其他化合物分解成有害物质,如酒精能分解成有害的甲醛,必须在特定波长的紫外光激发下才能起效;另外,传统的光触媒采用平板结构,受到粘合剂的影响,其吸附面积小,除菌除臭能力较差。因此,为了解决以上问题,亟待设计一种新型光催化空气消毒机。
