本发明实施例1中所述净化系统工作过程及原理:
雾霾空气通过加压风机1作用进入送风主管道15中,首先经由水介质净化器2,其能除去直径较小的颗粒物如PM2.5,还能提高空气的湿度,为后续的各种净化处理做准备以便于提高其净化效率。其后进入臭氧净化器4和光触媒净化器5,经由臭氧净化器4和光触媒净化器5来杀灭空气中的细菌、病毒以及各种微生物。雾霾空气经过杀菌后进入多层滤网过滤器10,该多层滤网过滤器10采用了“活性炭-人造纤维-活性炭”的三层过滤模块,能有效地除去雾霾空气中大多数的颗粒物。其后空气通过积尘检测器11,若空气的质量达标则主阀门打开空气由HEPA膜处理后进入下一环节,若空气质量不达标则经由侧阀门12进入回送管7,再次多层滤网过滤器10中处理。经过处理的清洁空气再由新风系统输送到各个房间,其中在输送前可以调节空气的湿度。在所有程序中,当系统不需要工作停止运行时,滤网清洁喷头23将启动开始运行,利用水为介质除去沉积于滤网上的灰尘;而后介质水将流入循环再利用系统中,通过处理后将洁净水输送到主水管中以待系统再次利用。
水介质净化器2的原理:利用循环水直接(或通过填料层)喷淋不饱和空气就可获得降温的效果,水介质净化器2下方设有废水收集槽Ⅰ21,循环水经过水泵送至填料层上部,均匀的喷洒在填料层上,水依靠重力下流并润湿填料;空气由于风机作用穿过填料层并与水进行热湿交换,空气将显热传递给水,温度降低,水蒸发进入空气,空气的含湿量和潜热增加。当蒸发冷却器正常运行时,可以有效的降低空气温度,且颗粒物去除效率也有效提高。润湿的填料对颗粒物的粘着力增大的同时,也削弱了颗粒物再次悬浮的能力。填料吸水后会出现轻微的膨胀。填料的轻微膨胀会增大其接触面积,惯性碰撞和接触阻留作用的去除效果增强。蒸发冷却器中主要运用了惯性碰撞、扩散、接触阻留和沉降的机理来去除雾霾中的颗粒物,以净化空气。当雾霾气体进入水介质净化器时,由水介质净化器2的顶部设有喷头3喷出水以湿润填充物;(其中喷头3以进水管26的水为水源)雾霾空气(此时空气成分为剩余PM2.5、残余粉尘和氧气)通过湿润的填料层时利用惯性碰撞、扩散、接触阻留和沉降的机理能够除去绝大多数PM2.5和残余粉尘,还能提高空气的湿度。
当涂料层中的水和混有杂质的污水从填充物支撑板25渗透下来后,通过倾斜面的作用进入到装置下方的废水收集槽Ⅰ21中,通过水管将部分水会回收置于废水静置室20中,废水静置室20与喷头的进水管26相连接而实现循环利用,其余水则通过集水槽的废水管排出。
杀菌系统的原理:由臭氧净化器4和光触媒净化器5组成,雾霾空气首先经由臭氧净化器4处理后再通过光触媒净化器5净化;关于臭氧净化器4,其是通过放置在其中的高频放电器产生大量的等离子体,高能电子与气体分子碰撞发生物化反应,并激活气体产生多种自由基和臭氧;雾霾空气中含有可吸入颗粒物(PM2.5)、细菌病原体、二氧化硫和氮氧化物以及各种微小粉尘,其中以PM2.5为主要污染物;当雾霾空气进入臭氧净化器4后,通过臭氧的强氧化作用,在低浓度下就能瞬间氧化降解有机气体,从而杀灭病原微生物。因而能够对空气中的有毒气体(如甲醛、氮硫氧化物等)、细菌、病毒起到净化作用。但是臭氧有臭味,虽然在常温常压下不稳定、易分解为氧气;但是仍有部分未分解的臭氧会跟随其余气体进入下一环节中。而光触媒净化是将纳米级的二氧化钛作为光催化剂镀到普通的载体滤网上。在外界紫外线的作用下,光能转变为化学能。由于半导体能带的不连续性,电子和空穴的寿命较长,它们能够在电场作用下或通过扩散的方式运动,与吸附在半导体催化剂粒子表面上的物质发生氧化还原反应,或者被表面晶格缺陷俘获。其产生羟基自由基是一种高活性粒子,能够氧化多种有机物(有害气体、病毒蛋白等)并使之矿化。
多层滤网过滤系统的原理:多层滤网过滤器10采用了“活性炭-人造纤维-活性炭”的三层过滤模块。此处人造纤维选用的是市购方便的空气过滤用合成纤维过滤棉。当气体进入多层滤网过滤器10时,其首先经过“活性炭-人造纤维-活性炭”的三层结构的初效滤网;气体中的臭氧和颗粒较大的粉尘会被吸附或沉积于滤网的表面层,其能够有效吸附杂质和上一环节产生的臭氧;接着气体通过高效滤网,残余的有机物被处理、残余PM2.5被沉积,最终得到洁净空气。在滤网后面设计了高压喷头;当整个系统停止运行时,喷头会从与空气流动方向相反的方向喷水,以此将沉积在滤网上的灰尘(粉尘)打出,从而实现对滤网的清洁;至于清洁所产生的废物,则是由灰尘与水形成的污水一起滴落到下方的废水收集槽Ⅱ24内,后流入循环再利用系统。
在总的系统运行过程中,水介质净化器2、滤网清洁都用到了水这一介质,故此,通过废水收集槽将使用过的水收集沉降于废水静置室20中(杂质密度较大主要沉积在底部,因而上层的水质较好),然后把底层的杂质水通过废水排出管19排出;至于上层清澈、干净的水则用水泵17作动力通过循环水回收管6输送到进水管26完成一个水循环以便继续使用。
积尘检测系统原理:当空气经过积尘检测器11时,可检测出此时空气的质量状况;若空气的质量达标则主阀门打开空气进入调湿环节;若空气质量不达标则经由侧阀门进入另一管道,由HEPA膜处理后进入调湿环节;经过处理的清洁空气再由新风系统输送到各个房间。
