具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本发明实施例的组件可以以各种不同的配置来布置和设计。
因此，以下对在附图中提供的本发明的实施例的详细描述并非旨在限制要求保护的本发明的范围，而是仅仅表示本发明的选定实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例一
参见图1、图2、图3和图4，本实施例提出一种防生物污染空气净化***，包括送风***1、水浴净化***2和干燥阻液***3；
水浴净化***2与干燥阻液***3组成阻水透气的闭合空间4，送风***1、水浴净化***2和干燥阻液***3可根据使用环境需求，予以串联式连接或整合；
水浴净化***2产生的液珠微粒，通过闭合空间4内的气流达到干燥阻液***3；
在同一***中，送风***1、水浴净化***2和干燥阻液***3需有至少一个或多个；
在作为空调或中央空气循环***等有外接风源的终端净化器时，根据外接风源的具体情况可只包含水浴净化***2和干燥阻液***3。
本实施方案公开的防生物污染空气净化***通过风机9增压送风、净化液12的液面下横向输气、间断式多阶次分散、阻流板13延时、干燥阻液***3等一系列的综合性技术手段，***性的解决水浴净化***2阻力大、能效比低的问题，使气流在水浴净化***2中过液后依然能保持相当压力，有效透过干燥阻液***3，并利用气流中夹带的液体的冲刷作用，实现表面干燥阻液***3各部件的自清洁；
本发明通过将送风***1、水浴净化***2和干燥阻液***3以串联式连接或整合，使其符合市场需求，并且安全、可靠、高效，同时对物理、化学污染同样具有较好净化效果。
参见图1、图2、图3和图4，送风***1具有可提供一定风压的交流或直流风机9，风机9通过风管5或风道与水浴净化***2相互密封串联，风机9的静压力应≥800Pa，风机9最佳静压可为1200Pa～2500Pa范围，其额定能效比≥2.5m3/w·h，这使得流经送风***1、水浴净化***2和干燥阻液***3中的气流只能串联式的流通，避免没有经过水浴净化***2过滤的气流与经过水浴净化***2过滤的气流相接处，进而影响干燥阻液***3过滤的气流洁净度。
风机9的进风口处具有固定或可拆卸的可重复使用或一次性使用的初效过滤层11，初效过滤层11用于滤除外部环境中的粗颗粒物，避免其进入风机9内，而且将初效过滤层11设置为可重复使用或一次性使用。
参见图1、图2、图3和图4，水浴净化***2具有净化液12、阻流板 13和分散器14，阻流板13的阻流面可为平面式、倾斜式、波浪式、锯齿式，用于延长分散的气相流在液面下的存留时间，阻流板13的中部开设有通孔15，通孔15与风管5相互密封连接，阻流板13的外边缘具有出风口16，当阻流板13在工作状态下，出风口16位于净化液12的液面以下，当阻流板13在未工作状态下，出风口16位于净化液12的液面以上或以下；通孔15的风道轴心位置设有锥形导流罩18，锥形导流罩18与阻流板13之间形成气体通路19；送风***1将气流呈与净化液12的液面垂直或呈一定角度输入净化液12内，通过锥形导流罩18上的气体通路19，气流与液面平行或呈一定角度的方向横向分散，并在分散器14的整个气体通路19中设置多个孔/槽结构，通过分散器14对气流进行破碎并混入净化液12中；阻流板13的平面可与净化液12的液面完全平行，或与液面呈小于90°的正向或反向夹角，通过以分散器14对气流进行非连续的间断式分散，极大的减小了分散过程对气流的损耗，而阻流板13的设置，可有效阻隔出气口气流上浮，气流由阻流板13导引，在液面下以平行与液面或与液面呈一定角度的方向，横向移动，避免了因净化液12的液位设置较浅，气流与液体混合时间不足的缺陷，而且可根据需求任意延长气液混合时长，通过分散器14的应用，使***过水风量损耗≤20％，过水风压保留≥200Pa；
水浴净化***2内各方向的气流与液体混合物，在高速运动过程中，相互间不断循环碰撞，产生大量水珠微粒和负离子，在连续液相流、分散液相流、液珠微粒及负离子的大面积、全方位吸附作用下，空气中的尘埃粒子、VOCs、甲醛以及细菌、病毒等有害物质，均被捕获并驻留在溶液中，从而完成对污染物的净化工作。
分散器14过水风压保留应大于200pa；
未工作条件下，出风口16设计水位深度所产生的压强应不大于风机9额定风压，出风口16设计水位深度可设置为净化液12的液面以下下0cm～6cm范围，或液面以上1cm～液面以下2cm的范围，其最佳设置为液面以下 0cm～2cm范围，这使得出风口16的水压小于风机9的额定风压，便于风机9将气流压入净化液12并过滤后从出风口16排到闭合空间4，便于干燥阻液***3二次过滤。
净化液12中具有聚氨酯泡沫、活性碳颗粒、沸石粉多孔固体材料以片状、块状或球状，浸没于净化液12中，进一步分散气相流，增大接触面积，降低液面波动幅度，均衡腔内气流，减小***振动及噪音。
净化液12具有长效、安全、可再生，广谱杀菌、杀病毒净化液12；
净化液12成分包括但不限于：水、甘油、脂肪醇、脂肪多元醇、脂肪酮、植物油、动物脂肪、聚乙二醇和硅油，并且任选地包含一种或多种独立选择自以下组的添加剂：碱金属盐、聚乙二醇、溶菌酶、亚硫酸氢钠、炭黑、还原糖、维生素C、氧化锌、硝酸银、矿物酸、碳酸氢钠、氢氧化钠、漂白剂、季铵盐、甘油、水凝胶、水溶胶、高吸水剂、EDTA、硅胶、氧化铝、吸水粘土、有机聚合物，淀粉、氨基酸、环葡聚糖、C1-C6单、二或三烷基胺、聚合物胺、洗涤剂、杀菌剂、有机清除剂、香料、空气清新剂、能够降解污染物的微生物、洗涤剂、氨、消毒剂、水生植物、稀土金属催化剂和杀菌剂。

防泼溅过滤层6、冷凝干燥层7和超疏水阻液透气层8相互之间具有连通的液体收集流道，液体收集流道连通水浴净化***2，干燥阻液***3还具有对微粒的中高效过滤特性，可进一步提高对生物污染和物理污染的净化率，通过超疏水阻液透气层8的高效透气不透液特性，全面阻隔***内液体的溢出，提高了***可靠性和安全性，并且同时利用***中液相流的冲刷作用，实现超疏水阻液透气层8的自净化功能，有效避免了超疏水阻液透气层8表面易积尘失效的固有问题。
参见图1、图2、图3和图4，还包括液位保持***20和智能控制***21，液位保持***20具有液位传感器、液体浓度传感器、电动/手动阀门、电动/手动双向泵、冗余储液皿、注水管道、抽水管道、浓缩净化液12和微控制器，通过液位传感器和液体浓度传感器，实时检测水浴净化***2中净化液12液位高度及液体中净化液12浓度，并将监测数据传送至微控制器，由微控制器与标准值进行对比判断，根据判定结果控制阀门及泵进行补水、抽水和补充净化液12的动作，同时，也可提供预警提示，进行人工补液；

一种防生物污染空气净化***的工作原理是，图中箭头方向为气流运动方向，水浴净化***2，综合利用气液两相流中液相对气相杂质的净化性，通过***设计：整体结构设计、特定要求的风机9、多功能高效的净化液12和高效分散器14的共同作用，实现在较高能效比条件下，一次性对污染空气中粉尘微粒、VOCs、甲醛以及细菌、病毒的全面捕捉、净化、灭杀，从根本上解决了有害生物污染二次扩散的可能性；

在本实施例中，通过***性结构设计，整合功能模块、优化风道结构、降低风阻系数，避免不必要的各环节风量损失，在确保生物污染净化效果达到99.99％的前提下，使***能效比达到不低于2.0m3/w·h的实用化要求；
在本实施例中，通过大量试验验证，选配风压适宜的增压风机9。优选的，风机9能效比≥2.5m3/w·h，风压≥800Pa，可在保证***能效比前提下，为***提供具有一定势能的气流，以便更好的克服液体阻力和分散器14阻力；
在本实施例中，通过液面下横向输气，降低气体分散所需液位深度，减小水压阻力，扩大出气面积，确保过水气体仍具有足够渗透干燥阻液***33的气压，使过水风量损失≤20％，过水风压≥200Pa；通过间断式多阶次分散器14的设置，实现在较浅液位和较小风阻条件下的有效气流分散，并使分散气流与液体充分混合；通过具有一定宽度和面积的阻流板13，延长分散气体在液面下的行程和时间，在不显著增加能耗的前提下，提高净 化效率，试验测得净化效率≥98％。

在本实施例中，通过大量材料验证，优选了一种超疏水阻液透气层8(其孔隙直径可选范围：0.5μm～10μm)，作为气流过水后的阻液干燥层，该超疏水阻液透气层8具有超疏水特性，表面均匀分布微孔，既可在不显著降低风量的条件下有效透气，又可有效阻隔水浴净化后产生的大量液珠微粒散溢至空气中，此外，该超疏水阻液透气层8还具有对微粒的中高效过滤特性，可进一步提高对生物污染和物理污染的净化率。
实施例二
参见图1、图2、图3和图4，结合前述实施例一的内容，在本实施例中提出一种防生物污染空气净化***的净化方法：
首先，外部空气通过可重复使用或一次性使用的初效过滤层11，将外部空气进行初过滤，滤除较大尺寸尘埃物之后，外部空气进入风机9内，再通过风机9做功，形成具有一定压强和动能的单向气流进入风管5；
其次，风管5导引增压后的气流，以与净化液12的液面垂直或呈一定角度的方向，进入阻流板13中的进风口，当气流从出风口16高速流出时，被分散器14分散和破碎，使气流与净化液12混合为气液两相流，再通过阻流板13和锥形导流罩18相互之间的气体通路19，使气液两相流以平行于液面或与液面呈一定角度的方向，在液面下向四周横向扩散，延长分散的气液两相流在液面下的存留时间，提高气液混合效率，当水浴净化***2腔体内各方向的气液两相流在高速运动过程中，相互间不断循环碰撞，产生大量水珠微粒和负离子，在连续液相流、分散液相流、液珠微粒及负离 子的大面积、全方位吸附作用下，空气中的尘埃粒子、VOCs、甲醛以及细菌、病毒等有害物质，均被捕获并驻留在溶液中，实现全接触、全吸收；
再次，水浴分散***所净化的气流在较大的闭合空间4的气压作用下，流向干燥阻液***3，通过防泼溅过滤层6阻断水浴净化***2输送气流中所夹带的具有较大动能的大尺寸液珠，截流气流中一部分的较小液珠微粒,通过液体收集流道输送回水浴净化***2；
最后，防泼溅过滤层6过滤后的气流进入冷凝干燥层7，冷凝干燥层7以结露和吸湿的工作方式，截流并吸附气流中剩余的大部分液珠微粒和趋于饱和的水蒸气，通过防泼溅过滤层6及冷凝干燥层7的气流进入超疏水阻液透气层8表面，通过超疏水阻液透气层8过滤的气流排向空气中。
参见图1、图2、图3和图4，结合实施例一和实施例二，为了验证前述各参数和实现的技术效果，通过以下实验得出：
实验一：高效净化生物污染，净化率达99.99％。
空气中的物理、化学和生物污染，均在水浴净化***2内产生的连续液相流、分散液相流、液珠微粒及负离子的大面积、全方位吸附作用下，被捕获并驻留在净化液12内，其中，尘埃粒子等物理污染被净化液12中液体吸附、包裹而沉降，VOCs、甲醛等化学污染被净化液12或水中和、分解，细菌及病毒等生物污染被净化液12中的灭菌剂杀灭，从而同时完成对三种主要污染物的一次性综合净化工作，实现全接触、全吸收的高效净化，生物污染净化率达99.99％。
根据国家相关标准：GB/T 18801-2015《空气净化器》、GB 21551.1-2008《家用和类似用途电器的抗菌、除菌、净化功能通则》、GB 21551.3-2010《家用和类似用途电器的抗菌、除菌、净化功能空气净化器的特殊要求》、GB/T 16293-2010《医药工业洁净室(区)浮游菌的测试方法》，针对一种实施样机，进行了灭菌净化试验，测试方案及测试结果如下。
建立测试模型如下：
试验分为空白组、对照组和试验组，空白组不引入净化器，对照组净化器为一款市售家用型空气净化器，试验组为本发明五种实施样机净化器。实施机主要性能参数如下表1所示：
表1五种实施样机性能参数
对培养皿进行细菌培养七十二小时后，测试结果如下表2所示：
表2实施样机灭菌性能对比测试
注：表2中的实施2(连续运行500h)组，为实施2的耐久性测试组，从测试结果而言，各项性能与初始状态无明显差异，***耐用性得到初步验证。实施2(无干燥阻液***)组，为实施2取消了干燥阻液***3的状态，其灭菌性能仍可达98.35％，说明单独的水浴净化***2同样具有良好的防生物污染效果。
实验二：高效净化物理污染，PM0.3净化率达99％以上。
利用液体对尘埃粒子的吸附特性和超疏水阻液透气层8的表面阻隔过 滤性能，***除有优异的生物污染净化效率外，对物理污染同样具有较好的净化效率。参考国家相关标准：GB/T 18801-2015《空气净化器》,针对表1中的实施样机，进行了尘埃粒子的净化测试试验，测试方案及测试结果如下。
建立测试模型如下：
通过空气尘埃粒子计数器，测量试验环境中单位体积的颗粒物数量，以及经净化***过滤后的空气中单位体积的颗粒物数量，进行比值计算，以此确定各实施机的空气物理污染净化效率。试验分为空白组、对照组和试验组，空白组为环境中污染空气的测试数据，对照组净化器为一款市售家用型空气净化器，试验组为本发明五种实施样机净化器。
测试结果如下表3所示：
表3空气颗粒物净化测试(单位：个/L)
实验三：优化设计各环节风压、风阻，***总体能效比可达2.0m3/w·h。
(1)送风***1：为使输入的气流可压入净化液12的液面下一定深度，并能有效通过分散器14、防泼溅过滤层6、冷凝干燥层7和超疏水阻液透气层8等各环节，送风***1需采用可提高风压的中高压风机9，风机9静压力应≥800Pa，额定能效比≥2.5m3/w·h；
(2)水浴净化***2：为保证气流压入净化液12的液面下有效分散、破碎后，仍有满足***终端需求的风量和风压，用以透过干燥阻液***3，在水浴净化***2中，分散器14设计水位深度所产生的压强应不大于风机9额定风压。优选的，未工作条件下，水位深度可设置为净化液12的液面下0cm～6cm范围，或净化液12的液面上1cm～液面下2cm范围，更优选的，可设置为0cm～2cm范围。
此外，通过分散器14的横向送风设计，有效降低了过水阻力，其过水风量损耗不大于风机9额定风量的20％，过水风压保留大于200pa。
(3)干燥阻液***3：为确保终端输出风量，干燥阻液***3的总体风量损耗应≤15％。防泼溅过滤层6选用可水洗的初效过滤材料，冷凝干燥层7采用减小迎风面和流线型设计，超疏水阻液透气层8可选用孔隙直径在0.5μm～10μm的微孔超疏水膜(如聚偏氟乙烯等)。
参考国家相关标准：GB/T18801-2015《空气净化器》,针对表1中的实施样机，进行了出风量和过水风压测试试验，测试方案及测试结果如下。
建立测试模型如下：
测试实验使用流量计测得净化器的出风处风量，使用气压计测量水浴净化***2与干燥阻液***3形成的闭合空间4的腔内压力值。测试结果如下表4所示：
表4实施样机风量、风压测试

实验四：有效阻止净化液12和液体散逸，降低耗材损耗，阻隔管道污染，可靠保障使用安全。
干燥阻液***3，通过防泼溅过滤层6、冷凝干燥层7和超疏水阻液透气层8共同作用，内容物挥发量≤0.1mg/m3，环境绝对湿度增量≤5％，有效阻隔***内形成的液珠微粒散逸至环境中，确保使用安全性，使室内环境湿度处于适宜区间。并且在作为中央循环***的终端时，可有效阻隔管道污染，避免管道积尘形成二次污染扩散。
对本发明的五种实施样机进行内容物挥发量测试。为方便检测，将净化液12中的净化剂替换为氯化钠，并适当增加溶液浓度，参照标准GB/T1266-2006《化学试剂氯化钠》进行***净化剂(氯化钠替代)挥发量模拟测试，测试方案及测试结果如下。
测试方法：
(1)取净化***正常工作所需纯化水用量，将其与NaCl按一定比例均匀混合；
(2)将混合溶液取样留存后，将5L混合溶液注入水浴净化***2；
(3)启动净化***连续工作，按蒸发量实时定量补充纯化水，并记录；
(4)如此反复，直至净化***蒸发量为初始注入水量的4倍时，关闭净化***；
(5)取出水浴净化***2中剩余溶液，测量该溶液浓度，并与初始留样对比。
因溶菌酶为可食用灭菌剂，其挥发不造成负面影响，故采用溶菌酶灭菌组未列入测试。测试对象为表1中的实施2、3、5，以及实施2(连续运行500h)耐久试验组和实施2(无干燥阻液***3)试验组，测试结果如下表5所示：
表5实施样机内容物挥发量测试
从测试结果可以看出，在具有完整***的四个试验组中，每立方米气体NaCl挥发量均在0.1mg/m3以下，可认为溶出量极低或几乎无溶出，而无干燥阻液***3的试验组挥发量达1.175mg/m3。这表明，本发明干燥阻液***3具有优异的控制内容物溢出性能。
另一方面，本发明所采用的净化抗菌成分本身相对安全，且净化液12浓度均控制在≤1～2‰的范围内，故可确认***内容物挥发量极微小，净化剂耗损量小，安全系数高。
实验五：生物、化学和物理粉尘污染一次性综合高效净化，无分步环节，无利于生物污染滋长的空间死角。
本方案的净化过程在一个整体化的闭合空间4中，附带灭菌剂的气液两相流及高密度水雾，通过动态循环的方式，在扩散作用下，自然充满整个空间，粉尘、VOCs、甲醛、细菌、病毒的吸附和灭菌功能均同时完成，净化功能之间无物理空间阻隔，无净化死角，一次性综合完成所有净化功能，全面规避传统技术存在的风险。
实验六：***内高速气液两相流形成的高密度水雾，对超疏水阻液透气层8具有冲刷效用，实现***自清洁功能，大幅延长***使用寿命。
与常规过滤材料利用有一定厚度的多层细纤维交叠，对空气中尘埃通过范德华力吸附的过滤方式不同，本方案***中的超疏水阻液透气层8主要由超疏水微孔过滤膜构成，通过其自身材料具有的超疏水特性，以及高密度均匀分布的微孔进行表面过滤。因此，污染物只能被阻挡在其过滤层 表面，不会侵入其内部，但当表面污染物累积到一定程度时，将造成其微孔堵塞，性能降低甚至寿终失效。
因此，针对超疏水阻液透气层8所具有的这一表面阻隔功能特点，利用净化液12在内部空间的动态循环过程产生的高密度水雾，对超疏水阻液透气层8内表面形成液体冲洗效果，实现了对阻水层的自清洁作用，从根本上解决了超疏水阻液透气层8表面过滤膜，易积尘形成二次污染的固有缺陷。
实验七：净化液12长效、安全、可再生，广谱杀菌、杀病毒，沉淀分解粉尘及有毒有害物质，净化全过程无异味和有害物质产生。
常规空气净化器杀菌方式一般为高压静电、紫外光照射或光触媒等方式。其中高压静电存在产生臭氧问题，紫外照射存在衰减及无法透射问题，而光触媒则效率过低。
在本方案中，污染物在过滤过程中被净化液12所吸附，物理污染遇水后即刻被液体包容、沉降，化学污染被中和或分解，生物污染被杀灭，所有污染物均实现了无害化处理，因此从根本上阻断了污染物二次扩散的可能性。
实验八：“瀑布效应”产生大量负离子，利于环境污染物沉降，有益人体健康。
众所周知，在自然界中，台风或暴雨的威力迫使雨滴反复相互碰撞，从而随着水滴的进一步***和破碎，产生大量覆盖大面积的超无限小水粒子和负离子，彻底净化大气，这条自然法则常被称为“台风效应”。而本方案中，外部中高压空气通过水浴净化***2，与净化液12形成高速动态循环的气液两相流，气流、水流相互交叠碰撞，在***内部高度还原出微型台风效应，其产生的负离子通过超疏水阻液透气层8与洁净空气混合输送至外部空间，进一步实现了对环境的整体净化。
实验九：***可具有液位保持***20和智能控制***21，有效保证液 位恒定，确保***可靠性，并可根据环境变化实时调整净化程度及风量，节能环保。
充分利用成熟的多种传感器及微处理器控制技术，对内外空气污染浓度、温度、湿度、风量、液位等参数进行实时监控，并按照既定程序进行智能调节。
实验十：与常规过滤器相比，利用水溶液吸附净化，容污量显著提高，使用寿命长，耗材成本低。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
