具体实施方式
图1为相关技术中的家用空气净化器的结构示意框图，如图1所示，该空气净化器包括穿孔网版空气进口(01)、多层过滤网(02)、杀菌消毒设备及控制系统(03)、过滤风机(04)、净化器面板(05)以及洁净空气排气口(06)，其净化原理采用浓度扩散原理，局部反复循环的方法，将室内已有的空气进行净化，不断降低室内空气中的污染，在密闭条件下，将会造成室内的空气质量指标下降(氧气浓度降低，二氧化碳浓度升高，尽管过程缓慢)的问题。
本方案的适用场景：适应于大气环境质量欠佳地区的居住空间，养老院、保育院及其防止交叉感染要求高的场所。同样适应于名用建筑家庭住宅居住空间。系统配置：一般民用建筑，只配置送风型净化系统，而对于特殊时期、特殊环境的密闭隔离、地下设施，则还要配置排风型净化系统，以及特殊有效吸附不同毒剂类型的过滤吸附材料。
图2为本申请实施例提供的一种送风型动态过滤、静态杀菌消毒空气净化系统的结构示意框图。如图2所示，包括：粉尘过滤面板式进风口1、过滤吸附净化器2、静电驻极装置3、杀菌消毒装置4、抽送风动力装置5、杀菌消毒内部循环装置6、循环残余气体排放装置7、检测控制报警提醒装置8、设备箱体9和排风口10，其中，粉尘过滤面板式进风口和所述过滤吸附净化器相连，所 述静电驻极装置固定于所述过滤吸附净化器内部，所述过滤吸附净化器、所述杀菌消毒装置、所述抽送风动力装置、所述杀菌消毒内部循环装置、所述循环残余气体排放装置和所述检测控制报警提醒装置设置于所述设备箱体内。
粉尘过滤面板式进风口1包括装饰性面板101、插入式进风卡口102以及粗效过滤膜103，用于和进风口104紧密连接、导入空气以及过滤空气中的颗粒粉尘。其中，紧固装置示例性的可以是进口锁紧卡环105以及转动式自密封进气阀106。通过粉尘过滤面板式进风口1，将空气中较大颗粒的粉尘过滤，延长净化器内部高效吸附过滤装置的清洗周期。
过滤吸附净化器2包括组合过滤膜片固定框架、吸附过滤网以及HEPA(High efficiency particulate air Filter，高效空气过滤器)过滤网，所述组合过滤膜片固定框架为抽拉式设置，所述吸附过滤网由超细活性炭纤维织成并涂覆有光触媒催化剂。其中，HEPA过滤网为达到HEPA标准的过滤网，对于0.1微米和0.3微米的有效率达到99.998％，是烟雾、灰尘以及细菌等污染物最有效的过滤媒介，HEPA网的特点是空气可以通过，但细小的微粒却无法通过，其为国际上公认的最高效过滤材料。通过过滤吸附净化器2，有效吸附过滤病毒细菌和微小粉尘颗粒，包含PM2.5微尘，配合杀菌消毒装置经吸附阻隔在过滤膜表面和内部的细菌病毒杀灭，为空间提供洁净清新的空气，方便定期取出清洗，保证空气净化设备正常运行。
静电驻极装置3包括静电驻极机和静电驻极网，所述静电驻极网设置在所述吸附过滤网和所述HEPA过滤网之间，用于对所述吸附过滤网和所述HEPA过滤网的采用驻极体纤维生产的HEPA熔喷布进行静电处理。当熔喷布经过静电驻极装置处理后带有几千伏电压，由于静电的排斥作用使纤维扩散成网状孔洞，纤维间的尺寸远大于粉尘的尺寸，从而形成一种开放式结构。当粉尘经过熔喷过滤材料时，静电作用不仅能有效吸引带电粉尘粒子，而且以静电感应效应捕获极化的中性粒子。材料静电势越高，材料的电荷密度越大，带点电荷越多，静电作用越强。过滤效率增加，过滤阻力降低，纤维表面电荷密度增加，纤网贮存电荷能力也增强)，由此始终高效的过滤吸附气体中的PM2.5微小尘粒和搭载在这些载体上的细菌病毒。
杀菌消毒装置4包括紫外线杀菌消毒装置或臭氧杀菌消毒装置，用于定期 对所述过滤吸附净化器内部的吸附膜片进行杀菌消毒。
杀菌消毒内部循环装置6包括静音循环抽风机601、循环管道602和阀门配件603，用于在启动杀菌消毒运行程序时，关闭所述系统的进出口阀门，启动循环风机。其中，该阀门配件603可以是四瓣式转动密封阀。通过杀菌消毒内部循环装置6，再进入杀菌消毒运行程序时，关闭系统进出口阀门，启动循环风机，间保持系统内部气流高速循环，使得内部臭氧浓度均匀，保证对病毒细菌杀灭和有机废气的分解净化效果，使系统得到有效再生。
循环残余气体排放装置7包括静音排风机701、管道702以及排风口阀门配件703，用于将杀菌消毒后内部残留的空气排出至室外空间。通过循环残余气体排放装置7，将进行杀菌消毒后系统内部残留的气体排出到室外空间，防止系统再次启动吸附过滤净化程序时对室内空气质量的影响。
抽送风动力装置5包括静音强力抽风机和关联配件，用于将室外的空气抽进所述过滤吸附净化器2，以及将净化后的空气通过所述排风口10送回室内空间。通过抽送风动力装置5，将室外的空气抽进净化器，经吸附过滤净化后再通过送风口送到室内空间。
检测控制报警提醒装置8包括电器自控元器件、粉尘颗粒传感器、VOC传感器和阻力传感器，用于显示所述系统的运行状态，发送提醒通知以及接收APP小程序的远程遥控操作。
设备箱体9用于固定粉尘过滤面板式进风口1、过滤吸附净化器2、静电驻极装置3、杀菌消毒装置4、抽送风动力装置5、杀菌消毒内部循环装置6、循环残余气体排放装置7、检测控制报警提醒装置8以及排风口10。
本方案中，如图2所示，室外空气先经过粉尘过滤面板式进风口(粉尘过滤进口卡板)，相当于一级粗效过滤网，空气气流中含有的粉尘，花粉毛发、虫螨、烟雾气溶胶颗粒、部分病菌被过滤阻隔在过滤网上，然后经过进风口进入到净化设备内部，再经过HEPA过滤网，进一步将微小的烟雾气溶胶颗粒，可吸入颗粒物病菌等过滤阻隔在HEPA过滤网上，最后再经过催化光触媒处理后的活性炭纤维制作的吸附过滤网，将气体中的化学异味如甲醛、VOC及更小颗粒的粉尘、病菌捕捉过滤吸附在活性炭过滤网中，同时定时启动静电驻极装置，使得组成催化活性炭过滤网和HEPA过滤网的带有静电驻极的熔喷布，再次经 过静电驻极装置处理后带有几千伏电压，由于静电的排斥作用使纤维扩散成网状孔洞，纤维间的尺寸远大于粉尘的尺寸，从而形成一种开放式结构。当粉尘经过熔喷过滤材料时，静电作用不仅能有效吸引带电粉尘粒子，而且以静电感应效应捕获极化的中性粒子。材料静电势越高，材料的电荷密度越大，带点电荷越多，静电作用越强。过滤效率增加，过滤阻力降低，纤维表面电荷密度增加，纤网贮存电荷能力也增强使其具有更好的静电吸附作用，最大限度将空气中的粉尘及其搭载在这些载体上的细菌病毒吸附过滤净化。运行一定的时间，关闭抽风风机，关闭进出口阀门，启动紫外光催化氧化或臭氧发生器，同时启动杀菌消毒循环风扇，对系统进行杀菌消毒和活性炭吸附过滤网脱附再生，紫外光催化氧化装置可以使得催化触媒获取能量，分解吸附在表面的异味分子，当选择臭氧作为杀菌消毒手段时，臭氧发生器产生的臭氧达到一定的浓度后，在整个系统内部循环，对系统进行杀菌消毒。杀菌消毒工作完毕，启动排空风扇装置，打开自密封循环空气排气阀，将系统内部的残留气体排出到室外，然后关闭循环杀菌消毒系统，需要时再行启动过滤吸附净化运行程序。
本方案提供的送风型动态过滤静态杀菌消毒空气净化系统采用积极地主动送风和正压强制置换方式，主动输送新鲜洁净空气，使得洁净的空气始终充满整个室内空间，挤压空间气流通过门窗缝隙和洗手间厨房排风扇缝隙。而现有的室内空气净化器产品，是采用浓度扩散原理，局部反复循环的方法，将室内已有的空气进行净化，不断降低室内空气中的污染，在密闭条件下，将会造成室内的空气质量指标下降(氧气浓度降低，二氧化碳浓度升高，尽管过程缓慢)，而送风型动态过滤静态杀菌消毒空气净化系统则根本不会产生这样的后果，始终保持室内环境质量水平指标不打任何折扣(氧气浓度和二氧化碳浓度与室外空气中的指标基本保持一致)。
本方案的有益效果、技术特点如下：
通过静电驻极技术，定期为吸附过滤材料补充电荷，使得组成催化活性炭过滤网和HEPA过滤网的带有静电驻极的熔喷布，再次经过静电驻极装置处理后带有几千伏电压，由于静电的排斥作用使纤维扩散成网状孔洞，纤维间的尺寸远大于粉尘的尺寸，从而形成一种开放式结构。当粉尘经过熔喷过滤材料时，静电作用不仅能有效吸引带电粉尘粒子，而且以静电感应效应捕获极化的中性 粒子。材料静电势越高，材料的电荷密度越大，带点电荷越多，静电作用越强。过滤效率增加，过滤阻力降低，纤维表面电荷密度增加，纤网贮存电荷能力也增强使其具有更好的静电吸附作用，最大限度将空气中的粉尘及其搭载在这些载体上的细菌病毒吸附过滤净化。
系统运行时高效地将粉尘、PM2.5微尘、细菌病毒吸附过滤阻隔在吸附过滤层表面和内部微孔中，使其和空气分离，提高室内空间环境质量。也就是说，吸附过滤净化可以长时间连续运行，可以连续不断为室内空间提供信息案洁净的空气。
由于采用静态杀菌消毒方式，整个净化器空间体积很小，所以可以加大杀菌消毒强度，选择臭氧、紫外或微波吸附阻隔在过滤材料表面和内部的细菌病毒有效杀灭。亦即，杀菌消毒时间歇短时间或极短时间运行，这样消耗的电能功率就小，运行费用大大降低。同时还完成了在杀菌消毒过程中对吸附阻隔过滤材料的再生。
集保持过滤材料吸附效率技术装置、吸附过滤阻隔装置和杀菌消毒装置于一体，充分发挥各自独立的作用和相互协同作用。传统的室内空气净化器，基本上配置的是粗效、中效、高效过滤装置和同步杀菌消毒装置，其主要作用是过滤清除气体中的粉尘颗粒、微粒，乃至PM2.5，由于动态过程一定的风速和极其短暂的停留时间，无法有效杀灭气体中的病毒和细菌。而动态过滤净化、静态杀菌消毒空气净化系统则彻底克服了传统室内空气净化器的现有弊端，不仅有效将几乎所有已知的病毒细菌与人群活动空间阻隔，保证空间的安全，彻底防止交叉感，同时又能够彻底杀灭细菌病毒。动态过滤净化、静态杀菌消毒空气净化系统将细菌病毒过滤阻隔与杀菌消毒分开处理，既不过多增加现有系统的设备投入，又解决现有系统的无法解决的问题。
上述送风型动态过滤、静态杀菌消毒空气净化系统的实施例中，所包括的各个单元和模块只是按照功能逻辑进行划分的，但并不局限于上述的划分，只要能够实现相应的功能即可；另外，各功能单元的具体名称也只是为了便于相互区分，并不用于限制本申请实施例的保护范围。
